Background: Osteoarthritis (OA) is typically associated with pain, but many patients are not treated.Methods: This point in time study explored factors associated with treatment status, using logistic regression of data from the Adelphi OA Disease Specific Programme conducted in the United States. Patients' treatment status was based on physician-reported, current: 1) prescription medication for OA vs. none; and 2) physician treatment (prescription medication and/or recommendation for specified nonpharmacologic treatment for OA [physical or occupational therapy, acupuncture, transcutaneous electrical nerve stimulation, or cognitive behavior therapy/psychotherapy]) vs. self-management (no prescription medication or specified nonpharmacologic treatment).Results: The 841 patients (including 57.0% knee OA, 31.9% hip OA) reported mild (45.4%) or moderate or severe (54.6%) average pain intensity over the last week. The majority were prescribed medication and/or recommended specified nonpharmacologic treatment; 218 were not prescription-medicated and 122 were self-managed. Bivariate analyses showed less severe patient-reported pain intensity and physician-rated OA severity, fewer joints affected by OA, lower proportion of joints affected by knee OA, better health status, lower body mass index, and lower ratings for cardiovascular and gastrointestinal risks, for those not prescribed medication (vs. prescription-medicated). Multivariate analyses confirmed factors significantly (p < 0.05) associated with prescription medication included (odds ratio): physician-rated current moderate OA severity (vs. mild, 2.03), patient-reported moderate OA severity 6 months ago (vs. mild, 1.71), knee OA (vs. not, 1.81), physician-recommended (0.28) and patient-reported (0.43) over-the-counter medication use (vs. not), prior surgery for OA (vs. not, 0.37); uncertain income was also significant. Factors significantly (p < 0.05) associated with physician treatment included (odds ratio): physician-recommended nonpharmacologic therapy requiring no/minimal medical supervision (vs. not, 2.21), physician-rated current moderate OA severity (vs. mild, 2.04), patient-reported over-the-counter medication use (vs. not, 0.26); uncertain time since diagnosis was also significant. Patient-reported pain intensity and most demographic factors were not significant in either model.Conclusions: Approximately 1 in 4 patients were not prescribed medication and 1 in 7 were self-managed, although many were using over-the-counter medications or nonpharmacologic therapies requiring no/minimal medical supervision. Multiple factors were significantly associated with treatment status, including OA severity and over-the-counter medication, but not pain intensity or most demographics. [ABSTRACT FROM AUTHOR]

ABSTRACT Introduction. The Sexual Function Questionnaire (SFQ) is a self-report outcome measure of female sexual function. It has recently been refined to create a 28-item version (SFQ28) including the addition of a new arousal-cognitive domain. Aim. This study aimed to validate the SFQ28 in female sexual arousal disorder (FSAD) and hypoactive sexual desire disorder (HSDD) populations and to develop a screening cut-score for the arousal-cognitive domain. Methods. Women with FSAD (n = 222) and HSDD (n = 114) and 303 women without female sexual dysfunction (FSD) completed the SFQ28, the Female Sexual Distress Scale (FSDS), and the Sexual Quality of Life-Female (SQOL-F) at a clinic visit. Retests were performed within FSD groups only (FSAD: n = 92, HSDD: n = 183), using postal questionnaires 7-14 days later. The optimal cut-score for the arousal-cognitive domain was based on diagnostic tests of sensitivity and specificity from a receiver operating characteristic curve. Main Outcome Measures. Psychometric analyses. Results. The factor analysis confirmed the domain structure of the SFQ28. The SFQ28 demonstrated excellent internal consistency, test retest reliability and known groups validity, and good convergent validity with the FSDS and SQOL-F for all domains except pain. The sensitivity/specificity analysis determined a screening cut-score of 5 for the arousal-cognitive domain. Conclusion. Given the replication of the psychometric data and the cut-scores for each domain, the SFQ28 is a robust measure that can be used in women with either FSAD or HSDD.

Introduction: Satisfaction with medications prescribed for osteoarthritis (OA) varies; this study aimed to determine the factors associated with satisfaction in US patients and their physicians. Methods: This point-in-time study used the Adelphi OA Disease Specific Programme (physicians identified from public lists reported on nine consecutive patients diagnosed with OA [any joint]: physicians and patients completed questionnaires). Patient's demographic, clinical, and treatment characteristics associated with patient-reported and physician-rated overall satisfaction with, and expectations of effectiveness of, medication for OA were assessed using multivariate linear regression. Results: Responses from 572 patients (mean age 64.9 years, 60.5% female) currently prescribed medication for OA and 153 physicians (81 primary care, 35 rheumatologists, 37 orthopedic surgeons) were analyzed. Pain intensity was moderate or severe for 59.4% of patients. Greater patient-reported overall satisfaction with medication was significantly associated with (standardized beta, 95% confidence interval) exercise (0.12, 0.03–0.20), comorbid other musculoskeletal or painful conditions (vs none) (0.15, 0.06–0.24), and physicians' report that the best control had been achieved (0.12, 0.03–0.20); lack of efficacy was among factors associated with worse satisfaction. Greater patient-reported expectation of effectiveness was significantly associated with exercise (0.12, 0.03–0.21) and the most troublesome joint not being a knee, hip, or their back (0.08, 0.01–0.14). Greater physician-rated overall satisfaction with medication was significantly associated with their report that the best control had been achieved (0.18, 0.11–0.26), the most troublesome joint being a knee (0.08, 0.01–0.14), comorbid other musculoskeletal or painful conditions (0.07, 0.01–0.12), obesity (0.06, 0.00–0.11), and female patients (0.06, 0.00–0.11); lack of efficacy and adverse events/tolerability issues were among factors associated with worse satisfaction. For physicians, their report that the best control had been achieved (0.19, 0.11–0.27), the most troublesome joint being a knee (0.08, 0.00–0.15), improving (vs stable) OA (0.15, 0.07–0.24), and uncertain duration of OA (0.11, 0.02–0.21) were associated with greater perception that the medication was meeting patients' efficacy expectations. Conclusion: Although efficacy was strongly associated with both patients' and physicians' satisfaction with medication, other factors were also important, including exercise (for patients), tolerability (for physicians), and knee OA (for physicians).

Introduction: Atopic dermatitis (AD) severity was measured in two phase 3 US studies of crisaborole ointment, 2%, in patients aged ≥ 2 years using the Investigator's Static Global Assessment (ISGA), an FDA-recommended scale. Eczema Area and Severity Index (EASI) is a validated scale used globally to assess AD severity in clinical trials. The objective of this study is to aid interpretability of ISGA by translating ISGA scores to EASI scores. Methods: ISGA was mapped to EASI using published EASI severity strata by Chopra et al. and Leshem et al. and pooled data from phase 3 trials CrisADe CORE 1 and CORE 2, which evaluated crisaborole in patients aged ≥ 2 years with mild-to-moderate AD (crisaborole, n = 1016; vehicle, n = 506). Least squares mean (LSM) percentage change from baseline (%CFB) in EASI and proportion of patients with 50%, 75%, and 90% improvement (EASI-50, EASI-75, and EASI-90, respectively) on day 29 were computed for mapped EASI. The relationship between changes in ISGA and changes in EASI was assessed using data from three abrocitinib trials. Results: ISGA was mapped to EASI using 70,000 random simulations. LSM (standard error) for %CFB in mapped EASI at day 29 (crisaborole versus vehicle) was −26.3% (17) versus 45.2% (35) (P = 0.0671) using Chopra strata and −43.1% (4.6) versus −5.2% (8.4) (P < 0.0001) using Leshem strata. EASI-50, EASI-75, and EASI-90 rates were 72.1% versus 57.6%, 63.0% versus 47.8%, and 55.0% versus 40.1%, respectively, using Chopra strata (P < 0.0001 for each difference). These rates were 68.8% versus 54.0%, 54.8% versus 40.5%, and 38.9% versus 27.2%, respectively (P < 0.0001 for each difference) using Leshem strata. Mean two-point improvement in ISGA was comparable to EASI-90. Conclusion: Mapped EASI results were consistent with ISGA results in crisaborole phase 3 trials. Simulation methodologies yielded consistent results and may aid in interpretability of ISGA across clinical studies. Trial Registration: ClinicalTrials.gov identifier: NCT02118766, NCT02118792.

Introduction: Most patient-reported outcome (PRO) instruments that measure atopic dermatitis (AD) symptoms do not have sufficient documented evidence of content validity to satisfy regulatory agency guidance for inclusion in product-labelling claims in the USA or Europe. The objective of this study was to develop a PRO instrument in accordance with regulatory agency guidance to assess daily AD symptoms during the course of therapy and to establish its content validity and psychometric properties.The Pruritus and Symptoms Assessment for Atopic Dermatitis (PSAAD) daily diary was developed based on qualitative interviews with US adolescents and adults with mild-to-severe AD. Content validity, test–retest reliability, internal consistency reliability, clinically important difference, clinically important responder, convergent validity, and known-group validity were evaluated using correlational and regression methods from phase 2b data from US adults with moderate-to-severe AD who were treated with abrocitinib.Patient interviews conducted with US adolescents and adults with mild-to-severe AD identified 11 relevant symptoms (itch, dryness, redness, flaking, discolouration, pain, bleeding, cracking, bumps, swelling, and weeping/oozing) for inclusion in the PSAAD instrument. All PSAAD psychometric parameters were acceptable based on phase 2b data from US adults with moderate-to-severe AD. Convergent validity and known-group validity were confirmed by significant correlations between PSAAD and six other PRO measures (r = 0.24–0.91, all p ≤ 0.01) and Dermatology Life Quality Index category (p ≤ 0.0001), respectively.Evidence supports the PSAAD instrument validity, reliability, responsiveness and definitions of clinically important changes/differences for adults with moderate-to-severe AD.Methods: Most patient-reported outcome (PRO) instruments that measure atopic dermatitis (AD) symptoms do not have sufficient documented evidence of content validity to satisfy regulatory agency guidance for inclusion in product-labelling claims in the USA or Europe.

Background/Objectives: Crisaborole ointment, 2%, is a nonsteroidal phosphodiesterase 4 inhibitor for the treatment of mild‐to‐moderate atopic dermatitis (AD). This pooled post hoc analysis of two phase 3 trials (NCT02118766, NCT02118792) assessed improvement and time to improvement in Investigator's Static Global Assessment (ISGA) and Severity of Pruritus Scale (SPS) outcomes in pediatric patients with mild‐to‐moderate AD. Methods: Patients aged ≥2 years were randomly assigned 2:1 to receive twice‐daily crisaborole or vehicle for 28 days. Patients aged 2‐17 years were pooled for this analysis. Proportions of patients and time to achieving ISGA success (clear [0] or almost clear [1] with ≥2‐grade improvement from baseline), ISGA clear/almost clear, ≥1‐grade improvement in ISGA, SPS success (SPS score ≤1 with ≥1‐grade improvement), or ≥1‐grade improvement in SPS score were analyzed and stratified by baseline ISGA. Results: At first postbaseline assessment (day 8), significantly higher proportions of crisaborole‐ than vehicle‐treated patients achieved ISGA success, ISGA clear/almost clear, ≥1‐grade ISGA improvement, SPS success, or ≥1‐grade improvement in SPS regardless of baseline ISGA. Differences were significantly greater over time for all outcomes for patients with moderate baseline ISGA and numerically greater for those with mild baseline ISGA. Median times to ISGA and SPS outcomes were shorter for crisaborole versus vehicle. Conclusion: Improvement in ISGA and SPS outcomes were observed with crisaborole in pediatric patients with mild‐to‐moderate baseline AD. [ABSTRACT FROM AUTHOR]

Atopic dermatitis (AD) is a chronic inflammatory skin disease associated with itch, eczematous lesions and impaired quality of life (QoL). Although the frequency of skin pain in AD is often underestimated, it is associated with a substantial health burden, similar to itch and is known to contribute to sleep disruption and mood disturbance. Abrocitinib is an oral, once-daily, selective Janus kinase-1 inhibitor approved for the treatment of moderate-to-severe AD. In phase 3 clinical trials JADE MONO-1 (NCT03349060) and JADE MONO-2 (NCT03575871), abrocitinib demonstrated rapid relief from itch and skin pain, as well as meaningful improvements in QoL compared with placebo. The interrelationships between abrocitinib treatment and improvements in itch, skin pain and QoL have not yet been investigated. This mediation analysis aimed to characterize the effect of abrocitinib treatment via itch and skin pain on dermatology-specific QoL in patients with AD. Data from JADE MONO-1 and JADE MONO-2 were pooled in this analysis. Adult patients with moderate-to-severe AD received abrocitinib (200 or 100 mg) as monotherapy or placebo for 12 weeks. Three separate models were evaluated whereby QoL was assessed using the Dermatology Life Quality Index (DLQI) score, and itch and skin pain were assessed via the Pruritus and Symptoms Assessment for Atopic Dermatitis (PSAAD) items #1 (How itchy was your skin over the past 24 h?) and #2 (How painful was your skin over the past 24 h?), respectively. The cross-sectional mediation model (CSMM) was run separately at weeks 2, 4, 8 and 12 using all available data at each timepoint. The longitudinal mediation model (LMM), which does not assume independence among measurements of itch, skin pain and DLQI at each timepoint, estimated relationships using all available data from all weeks simultaneously. Based on the results of the CSMM and LMM, a pseudosteady-state model, in which the relationship among variables was assumed to be the same across timepoints, was applied. Effects with P<0.05 were considered statistically significant. In the CSMM, the indirect effect of abrocitinib on DLQI mediated via itch was considered approximately stable (24–30%) for the first 8 weeks before increasing at week 12 (42%), while the indirect effect mediated via skin pain was considered approximately stable from week 2 to week 12 (33–41%). In the LMM, the indirect effect of abrocitinib treatment on DLQI mediated via both itch and skin pain was considered approximately stable from week 2 to week 12 (17–26% and 42–48%, respectively). The cross-sectional and longitudinal models were generally consistent and indicated a pseudo-steady-state period between weeks 2 and 12. Using the pseudo-steady-state model, the direct effect of abrocitinib on DLQI was estimated to be 34.8% (P<0.0001), and the indirect effects mediated via itch and skin pain were estimated to be 19.5% and 45.8%, respectively (P≤0.0001 for both). Improvements in dermatology-specific QoL with abrocitinib are mostly mediated indirectly via a reduction in skin pain and less so by relief of itch. These findings warrant further research to examine to what extent patients consider itch and skin pain as separate concepts in terms of their impact on dermatology-specific QoL.

Atopic dermatitis (AD) is a chronic inflammatory skin disorder characterized by intense itch, skin pain and impaired quality of life. Skin pain is a common and bothersome symptom of AD and increases in prevalence and intensity with worsening disease severity. Abrocitinib is an oral, once-daily, selective Janus kinase-1 inhibitor approved for the treatment of moderate-to-severe AD. Abrocitinib treatment resulted in improvements in skin clearance as well as rapid itch reduction in patients with moderate-to-severe AD across multiple phase 3 studies. Work productivity loss and activity impairment were assessed in the phase 3 JADE MONO-2 (NCT03575871) trial, with greater improvements being associated with abrocitinib treatment compared with placebo. The mechanism(s) through which abrocitinib reduces work productivity loss and activity impairment are unclear. To describe the interrelationships among abrocitinib treatment, itch, skin pain, and work productivity and activity impairment using a mediation modelling analysis in patients with AD. Data from adult patients treated with abrocitinib monotherapy (200 or 100 mg) or placebo in JADE MONO-2 were included in this analysis. As separate outcomes, work productivity loss and activity impairment (outcome variables) were measured by the Work Productivity and Activity Impairment Questionnaire: Atopic Dermatitis version 2.0 (WPAI-AD 2.0). Itch and skin pain (mediator variables) were evaluated using the Pruritus and Symptoms Assessment for Atopic Dermatitis (PSAAD) item #1 (How itchy was your skin over the past 24 h?) and item #2 (How painful was your skin over the past 24 h?), respectively. Mediation modelling was conducted independently for work productivity loss and activity impairment. All available data at week 12 were used in the modelling. Effects with P<0.05 were considered statistically significant. The direct effects of abrocitinib were estimated to be 7.3% (P=0.779) and 17.5% (P=0.258) on work productivity loss and activity impairment, respectively. The indirect effects of abrocitinib treatment on work productivity loss and, separately, on activity impairment mediated via itch were estimated to be 50.6% (P=0.017) and 20.9% (P=0.062), respectively, and via skin, pain were estimated to be 42.1% and 61.5%, respectively, (P<0.05 for both). The indirect effect of abrocitinib treatment on work productivity loss is mediated approximately equally through the reduction in itch severity and skin pain. The effect of abrocitinib treatment on activity impairment is mostly mediated indirectly through the reduction of skin pain, along with a smaller indirect contribution from the reduction in itch. These findings support further research into the extent that patients consider itch and skin pain as separate concepts in terms of their impact on work productivity. [ABSTRACT FROM AUTHOR]

Background: The Functional Assessment of Cancer Therapy-Kidney Symptom Index Disease-Related Symptoms (FKSI-DRS) is important to gauge clinical benefit in metastatic renal cell carcinoma (mRCC).Objectives: To estimate important difference (ID) in FKSI-DRS scores that is considered to be meaningful when comparing treatment effect between groups, using mRCC trial data.Methods: Data were derived from two pivotal phase III mRCC trials comparing sunitinib versus interferon alfa (N = 750) in first-line mRCC, and axitinib versus sorafenib (N = 723) in second-line mRCC. The change from baseline in FKSI-DRS score was examined as a function of a set of anchors using the repeated-measures model. Several anchors were evaluated: FKSI item "I am bothered by side effects of treatment," EuroQol five-dimensional questionnaire utility score, and adverse events.Results: When the "I am bothered by side effects of treatment" score was used as an anchor, the ID ranged between 1.2 and 1.3 points. When change in the EuroQol five-dimensional questionnaire utility score was used as an anchor, the FKSI-DRS ID ranged between 0.62 and 0.63 points. Selecting the adverse events that corresponded to a maximum worsening in the FKSI-DRS score in either trial, the ID ranged between 0.62 and 0.74 points.Conclusions: Among patients undergoing treatment for mRCC, between-group differences in FKSI-DRS scores as low as 1 point might be meaningful.

Introduction. In a previous paper using mediation modeling, the direct and indirect effects of sildenafil on erection maintenance were demonstrated. Objective. In an extension of this previous work, the historical psychosocial paradigm of ED, which focuses on performance anxiety, is tested by using mediation modeling to define the relationship of the physiological aspects (hardness and maintenance) and the associated psychosocial aspects (confidence, sexual relationship satisfaction, and performance anxiety) of ED. Methods. Statistical mediation analysis using the following outcomes from a double-blind placebo-controlled trial of fixed-dose sildenafil 100 mg or 50 mg: Erection Hardness Score; the 15-item International Index of Erectile Function (IIEF), including item 4 (frequency of erection maintenance after penetration) and item 5 (difficulty of erection maintenance to intercourse completion); the Self-Esteem And Relationship questionnaire; and the question, “Do you feel anxious about your next attempt at sexual intercourse?” Main Outcome Measures. Estimated percentages of direct and indirect effects of sildenafil on psychosocial aspects of ED (95% confidence intervals). Results. The model estimated that erection hardness mediated 43.7% (29.3%, 62.4%) of the effect of treatment onto confidence and 45.9% (32.2%, 61.8%) of the effect of treatment onto sexual relationship satisfaction, and that erection maintenance (using IIEF item 4 as a proxy) mediated 23.0% (10.1%, 39.1%) and 22.4% (10.1%, 36.5%), respectively. Similar results were obtained when IIEF item 5 was used as the proxy for measurement of maintenance. Of all possible paths to performance anxiety, only that from treatment via confidence was statistically significant, mediating an estimated 88.6% (55.5%, 146.2%; item 4 model) or 74.9% (47.0%, 121.0%; item 5 model) of the effect of treatment onto anxiety. The direct path to anxiety from treatment was not statistically significant. Conclusions. In men treated with sildenafil for ED, performance anxiety might be ameliorated by improved confidence. Improved confidence might be mainly mediated via increased erection hardness. Althof SE, Berner MM, Goldstein I, Claes HIM, Cappelleri JC, Bushmakin AG, Symonds T, and Schnetzler G.

Introduction. Erectile dysfunction (ED) is defined as the inability to attain and/or maintain penile erection sufficient for satisfactory sexual performance. Although intuitively related, the link between erection hardness and erection maintenance has not been formally established and quantified. Aim. To understand the components of erection maintenance through statistical modeling. Methods. Data from a double-blind placebo-controlled trial of fixed-dose sildenafil (100 or 50 mg, 8 weeks) with open-label extension of flexible-dose sildenafil (100 and 50 mg, 4 weeks) were analyzed. Erection maintenance was assessed with item 4 (how often erection was maintained) or item 5 (difficulty in maintaining erection) of the International Index of Erectile Function (IIEF). Erection hardness was assessed with the Erection Hardness Score. Main Outcome Measures. Longitudinal modeling estimated mean treatment differences averaged over the double-blind phase for sildenafil 100 mg vs. placebo and 50 mg vs. placebo. Statistical mediation analysis was applied to partition the effect of sildenafil (pooled into one treatment group) on erection maintenance directly and indirectly through erection hardness. Results. Longitudinal mean differences for sildenafil 100 and 50 mg vs. placebo were high ( P < 0.0001 for each), with large standardized effect sizes (>0.8). Mediation modeling showed that sildenafil treatment affected maintenance directly as well as indirectly via erection hardness, when measured by IIEF item 4 (direct effect, 44.6%; indirect effect, 55.4%) or IIEF item 5 (direct effect, 56.9%; indirect effect, 43.1%). Conclusions. Sildenafil treatment significantly improved erection maintenance, a physiologic requirement for satisfactory sexual performance. According to our model, only approximately half of the effect of sildenafil on erection maintenance was estimated to be driven through direct effects. Rather, the effect of sildenafil on erection maintenance seems to be substantially driven by erection hardness. Therefore, achievement of optimal initial erection hardness appears to be an important treatment goal for enhancing erection maintenance and achieving successful ED treatment.

Background: Pruritus is a common, bothersome symptom for patients with mild-to-moderate plaque psoriasis (PsO), yet no validated scale assesses it in this patient population. We aimed to validate the Peak Pruritus-Numerical Rating Scale (PP-NRS) using data from a Phase 2b study investigating the efficacy of brepocitinib in patients with mild-to-moderate chronic PsO., Methods: Patients completed the PP-NRS daily from baseline for the first 2 weeks after the dose administration and subsequently only on visit days. Test-retest reliability (intraclass correlation coefficient [ICC]), construct validity (known group validity and convergent validity), ability to detect change, and meaningful within-patient change (MWPC) were evaluated using correlation and regression analyses., Results: The PP-NRS demonstrated acceptable test-retest reliability (ICC: 0.86-0.89). Known-group evidence demonstrated that PP-NRS scores could discriminate between different degrees of disease severity. Convergent validity was supported by significant correlation coefficients between the PP-NRS and Patient Global Assessment (PtGA), Dermatology Life Quality Index, and Psoriasis Symptom Inventory, which generally exceeded 0.50. The ability to detect change was evidenced by an approximately linear relationship between changes in PP-NRS and Physician Global Assessment or PtGA of psoriasis scores. The value of 2.8 was determined as the MWPC for the PP-NRS., Conclusions: PP-NRS is a reliable, practical test for assessing pruritus in mild-to-moderate PsO clinical trials., Gov Identifier: NCT03850483., (© 2024 The Author(s).

Background: Tofacitinib is an oral Janus kinase inhibitor for treatment of ankylosing spondylitis (AS). Time to improvement in core domains of AS was estimated in tofacitinib-treated patients with AS., Methods: This post hoc analysis used phase 3 trial data from patients with AS receiving tofacitinib 5 mg twice daily or placebo to week (W)16; all patients received open-label tofacitinib W16-48., Outcomes: nocturnal pain; total back pain; fatigue, spinal pain, peripheral joint pain/swelling, enthesitis, and morning stiffness (Bath AS Disease Activity Index [BASDAI] questions 1-6); BASDAI total score; AS Disease Activity Score (ASDAS). Median time to improvement events was estimated using non-parametric Kaplan-Meier models. Improvement events were defined as initial (first post-baseline observation) and continued (sustained for 2 consecutive visits) ≥ 30% and ≥ 50% improvement in back/nocturnal pain or BASDAI questions/total scores, or ASDAS improvement ≥ 1.1 and ≥ 2.0 points., Results: 269 patients (tofacitinib: n = 133; placebo-to-tofacitinib: n = 136) were assessed. Median time to improvement was shorter, and more patients experienced improvements with tofacitinib vs. placebo-to-tofacitinib; differences observed from W2 (first post-baseline assessment). Median time to initial (continued) ≥ 30% pain improvement was 4 (4-8) weeks for tofacitinib vs. 24 (24) weeks for placebo-to-tofacitinib (8 [8] weeks post-switch). Median time to initial (continued) ≥ 50% improvement of pain, peripheral joint pain/swelling and enthesitis, morning stiffness, BASDAI total score, and fatigue was 8-24 (12-40) weeks with tofacitinib vs. 24-32 weeks (32 weeks-not estimable [NE]) with placebo-to-tofacitinib. Median time to initial (continued) ASDAS improvement ≥ 1.1 points was 4 (8) weeks for tofacitinib vs. 24 (24) weeks for placebo-to-tofacitinib, and NE for improvement ≥ 2.0 points with either treatment., Conclusions: Improvements in AS core domains occurred more rapidly with tofacitinib vs. placebo-to-tofacitinib. Half of tofacitinib-treated patients with AS will likely experience improvements ≥ 30% in pain and ≥ 1.1 points in ASDAS during month (M)1, ≥ 50% improvement in nocturnal pain and enthesitis by M2, and in morning stiffness by M3. Results show that initiating tofacitinib as soon as possible is associated with quicker improvements in AS core domains vs. delaying treatment., Trial Registration: ClinicalTrials.gov, NCT03502616, 11 April 2018., (© 2024.

Background: To illustrate how (standardised) effect sizes (ES) vary based on calculation method and to provide considerations for improved reporting., Methods: Data from three trials of tanezumab in subjects with osteoarthritis were analyzed. ES of tanezumab versus comparator for WOMAC Pain (outcome) was defined as least squares difference between means (mixed model for repeated measures analysis) divided by a pooled standard deviation (SD) of outcome scores. Three approaches to computing the SD were evaluated: Baseline (the pooled SD of WOMAC Pain values at baseline [pooled across treatments]); Endpoint (the pooled SD of these values at the time primary endpoints were assessed); and Median (the median pooled SD of these values based on the pooled SDs across available timepoints). Bootstrap analyses were used to compute 95% confidence intervals (CI)., Results: ES (95% CI) of tanezumab 2.5 mg based on Baseline, Endpoint, and Median SDs in one study were - 0.416 (- 0.796, - 0.060), - 0.195 (- 0.371, - 0.028), and - 0.196 (- 0.373, - 0.028), respectively; negative values indicate pain improvement. This pattern of ES differences (largest with Baseline SD, smallest with Endpoint SD, Median SD similar to Endpoint SD) was consistent across all studies and doses of tanezumab., Conclusion: Differences in ES affect interpretation of treatment effect. Therefore, we advocate clearly reporting individual elements of ES in addition to its overall calculation. This is particularly important when ES estimates are used to determine sample sizes for clinical trials, as larger ES will lead to smaller sample sizes and potentially underpowered studies., Trial Registration: Clinicaltrials.gov NCT02697773, NCT02709486, and NCT02528188., (© 2024.

Objective: We examined the relationships of work productivity and activity impairment with key patient-reported outcomes (PROs) assessing pain, disease activity, and health-related quality of life (HRQoL) in patients with ankylosing spondylitis (AS)., Methods: This post hoc analysis pooled available data from baseline to end of the double-blind phase of phase 2 and 3 placebo-controlled tofacitinib trials in patients with active AS. A repeated-measures longitudinal model assessed the relationships (linear or nonlinear) between Work Productivity and Activity Impairment questionnaire in Spondyloarthritis (WPAI:SpA) domains (absenteeism, activity impairment, presenteeism, and productivity loss) as outcomes and key PROs (total back pain, nocturnal spinal pain, Patient Global Assessment of Disease Activity, AS Quality of Life, EuroQol 5-Dimension 3-Level [EQ-5D-3L], and EQ-5D Visual Analog Scale [EQ-5D-VAS]) as predictors., Results: Data from 330 to 475 patients were available, depending on the analysis. Relationships between WPAI:SpA domains and PROs were approximately linear. The worst PRO scores were associated with a decline in patients' work capacity (measured by activity impairment, presenteeism, and productivity loss [>65%]); the best scores were associated with improvements in WPAI:SpA domains (8%-23%). Incremental PRO improvements were associated with improvement of activity impairment, presenteeism, and productivity loss. Relationships between absenteeism and PROs were the weakest, owing to absenteeism being low in the study population., Conclusion: Evidence of linear relationships between work productivity and activity impairment with patient-reported pain, disease activity, and HRQoL was observed. Interventions to control pain and disease activity and improve HRQoL are therefore likely to improve work productivity and reduce activity impairment in patients with AS., (© 2023 Pfizer Inc and The Authors.

Objectives: The FDA recommends the use of anchor-based methods and empirical cumulative distribution function (eCDF) curves to establish a meaningful within-patient change (MWPC) for a clinical outcome assessment (COA). In practice, the estimates obtained from model-based methods and eCDF curves may not closely align, although an anchor is used with both. To help interpret their results, we investigated and compared these approaches., Methods: Both repeated measures model (RMM) and eCDF approaches were used to estimate an MWPC on a target COA. We used both real-life (ClinicalTrials.gov: NCT02697773) and simulated data sets that included 688 patients with up to six visits per patient, target COA (range 0 to 10), and an anchor measure on patient global assessment of osteoarthritis from 1 (very good) to 5 (very poor). Ninety-five percent confidence intervals for the MWPC were calculated by the bootstrap method., Results: The distribution of the COA score changes affected the degree of concordance between RMM and eCDF estimates. The COA score changes from simulated normally distributed data led to greater concordance between the two approaches than did COA score changes from the actual clinical data. The confidence intervals of MWPC estimate based on eCDF methods were much wider than that by RMM methods, and the point estimate of eCDF methods varied noticeably across visits., Conclusions: Our data explored the differences of model-based methods over eCDF approaches, finding that the former integrates more information across a diverse range of COA and anchor scores and provides more precise estimates for the MWPC.

Background: Tofacitinib is an oral small molecule Janus kinase inhibitor for the treatment of ulcerative colitis [UC]. We evaluated the relationship between Mayo/Inflammatory Bowel Disease Questionnaire [IBDQ] scores and Work Productivity and Activity Impairment-UC [WPAI-UC] components in patients with UC., Methods: All available pooled data from three Phase 3 tofacitinib studies [OCTAVE Induction 1 and 2 and OCTAVE Sustain] were included. Relationships were estimated using repeated measures regression models with Mayo score/subscores or IBDQ total/domain scores as a separate anchor predictor and WPAI-UC components as the outcome., Results: Evidence for linear relationships was confirmed between Mayo/IBDQ scores and WPAI-UC components. Robust relationships between total Mayo score/IBDQ total score and WPAI-UC presenteeism, work productivity loss, and activity impairment were observed; relationships with absenteeism were weak. Total Mayo scores of 0 and 12 corresponded, on average, to WPAI-UC component scores of < 15% and ≥ 60%, respectively, and IBDQ total scores of 224 and 32 corresponded, on average, to WPAI-UC component scores of < 6% and ≥ 90%, respectively. Presenteeism, work productivity loss, and activity impairment [all 0-100%], respectively, improved on average by 14.7, 13.6, and 16.4 percentage points for every 3-point improvement in total Mayo score, and by 8.1, 7.9, and 8.8 percentage points for every 16-point improvement in IBDQ total score., Conclusion: Robust relationships between Mayo/IBDQ scores with WPAI-UC presenteeism, work productivity loss, and activity impairment suggest that patient productivity and non-work activities are strongly associated with disease activity and HRQoL. The weak relationships with absenteeism suggest that patients attend work regardless of their disease activity/poor HRQoL.

Objectives: To better understand the relationships among treatment, pain, and physical function (PF)., Methods: Data were collected from 2 published randomized clinical trials of osteoarthritis patients who received tanezumab or a placebo. PF was measured by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) PF domain. Pain (WOMAC pain domain) was a mediator of the effect of treatment on PF. A set of mediation models were investigated. Variables were treatment (tanezumab vs placebo), WOMAC pain domain, and WOMAC PF domain. Cross-sectional mediation models were assessed separately at different weeks. Longitudinal mediation models used data from all weeks simultaneously. Results could identify a steady-state period., Results: The cross-sectional and longitudinal mediation models showed a stable indirect effect of treatment through the pain on PF across time, indicating that a pseudo-steady-state model was appropriate. Therefore, the longitudinal steady-state mediation models were used with all available data assuming relationships among variables in the model being the same at all time points; results showed that the indirect effect of the treatment on PF was 77.8% in study 1 (NCT02697773) and 74.1% in study 2 (NCT02709486), both P <0.0001, whereas the direct effect was 22.2% for study 1 ( P = 0.0003) and 25.9% for study 2 ( P = 0.0019)., Discussion: At least 75% of the treatment effect of tanezumab on physical functioning can be explained by the improvements in pain. However, tanezumab had an additional effect on physical functioning (~25%) that, was independent of improvements in pain. Such independent effects are of considerable interest and require further research to determine their mechanisms., (Copyright © 2023 The Author(s). Published by Wolters Kluwer Health, Inc.)

Background: Patients with ulcerative colitis (UC) often report impaired health-related quality of life (HRQoL). Tofacitinib is an oral small molecule Janus kinase inhibitor for the treatment of UC. In addition to previous demonstrations of improved clinical measures (e.g., Mayo score), tofacitinib has been shown to improve HRQoL in patients with UC. This analysis explored the interrelationships among tofacitinib treatment, HRQoL, and disease activity (measured using Mayo subscores) using mediation modeling., Methods: Data were collected from two 8-week induction studies (OCTAVE Induction 1 and 2) in patients with moderate to severe UC treated with tofacitinib or placebo. Two mediation models were specified. First, Mayo subscores were mediators between the binary treatment variable (tofacitinib vs. placebo) and the eight Short Form-36 Health Survey (SF-36) domain scores as outcomes. Second, the four Inflammatory Bowel Disease Questionnaire (IBDQ) domain scores served as outcomes. Both models used data collected at week 8., Results: Overall, 1,073 and 1,079 patients were included in the SF-36- and IBDQ-based models, respectively. For all SF-36 domains, improvements in Mayo subscores were estimated to explain 65.6% (bodily pain) to 92.9% (mental health) of the total treatment effect on SF-36 domain scores (all p < 0.05). For all IBDQ domains, improvements in Mayo subscores explained 71.6% (systemic symptoms) to 84.7% (emotional function) of the total treatment effect (all p < 0.05)., Conclusion: Mayo scores and Mayo subscores are significant but incomplete contributors to tofacitinib's effect on HRQoL in patients with moderate to severe UC., Clinicaltrials: gov: NCT01465763; NCT01458951., (© 2023 The Author(s).

Background: The Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) scale has demonstrated good internal consistency and responsiveness to changes in clinical status among patients with ankylosing spondylitis (AS). We aimed to further evaluate the psychometric properties of the FACIT-F scale in adult patients with AS., Methods: Measurement properties of the FACIT-F scale were evaluated using data from tofacitinib phase 2/3 (NCT01786668/NCT03502616) studies in adult patients with active AS., Results: Second-order confirmatory factor modeling supported the measurement structure of the FACIT-F scale (Bentler's comparative fit index ≥ 0.91), and FACIT-F demonstrated excellent internal consistency (Cronbach's coefficient α ≥ 0.88) and test-retest reliability (Intraclass Correlation Coefficient ≥ 0.75). Correlation coefficients between FACIT-F and other patient-reported outcomes generally exceeded 0.40, supporting convergent validity. Meaningful within-patient change was estimated as 3.1-6.3 for FACIT-F total score, and 1.4-2.8 and 1.7-3.6 for FACIT-F Experience and Impact domain scores, respectively. Large (effect size ≥ 1.17 standard deviation units), statistically significant differences in FACIT-F domain/total scores between 'no disease activity' (Patient Global Assessment of Disease Activity [PtGA] = 0) and 'very active disease' (PtGA = 10) patient groups supported known-groups validity. Ability to detect change was evidenced by an approximately linear relationship between changes in FACIT-F and PtGA scores., Conclusions: FACIT-F is a reliable and valid measure for evaluating fatigue in adult patients with active AS., Trial Registration: ClinicalTrials.gov; NCT01786668 (registered 6 February 2013, https://clinicaltrials.gov/ct2/show/NCT01786668 ) and NCT03502616 (registered 11 April 2018, https://clinicaltrials.gov/ct2/show/NCT03502616 )., (© 2022.

Objectives: Evaluate relationships between changes in dermatologic assessments and quality of life (QoL) measures; quantify dermatologic symptom severity impacts on QoL in patients with psoriatic arthritis (PsA) treated with tofacitinib., Methods: Data were from two phase III studies; patients received tofacitinib 5 or 10 mg twice daily (BID), adalimumab 40 mg every other week, or placebo advancing to tofacitinib 5 or 10 mg BID at Month 3. Repeated measures longitudinal models assessed relationships between dermatologic assessments (predictors) Itch Severity Item (ISI), Physician's Global Assessment of Psoriasis (PGA-PsO), and Patient's Global Joint and Skin Assessment-Visual Analog Scale-Psoriasis question (PGJS-VAS-PsO), and QoL measures (outcomes) Dermatology Life Quality Index (DLQI) and Short Form-36 Health Survey Version 2 (SF-36v2). Models included one predictor and one outcome., Results: Direct, approximately linear relationships existed between predictors and outcomes. ISI/PGA-PsO/PGJS-VAS-PsO improvements from baseline of ≥3/≥2/≥40-mm VAS corresponded with clinically meaningful DLQI improvements; improvements from baseline of ≥4/≥3/≥40-mm VAS generally corresponded with clinically meaningful improvements across component scores and all SF-36v2 domains., Conclusions: Substantial links exist between dermatologic symptoms and QoL in patients with PsA, potentially informing patient-centered care and research. Rheumatologists should be aware of dermatologic manifestations and QoL impacts in patients with PsA., Clinicaltrials.gov: NCT01877668; NCT01882439.

Objective: To define meaningful within-patient change (MWPC) in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)., Methods: Data were analyzed separately from 3 phase III clinical trials (ClinicalTrials.gov: NCT02697773, NCT02709486, NCT02528188) of tanezumab, a novel treatment intended for the relief of signs and symptoms of moderate-to-severe osteoarthritis (OA), administered subcutaneously every 8 weeks. Patients with moderate-to-severe OA of the hip or knee completed the WOMAC and patient global assessment of OA (PGA-OA) at regular timepoints. A repeated measures longitudinal model with change in WOMAC Pain, Physical Function, or Stiffness domain score as the outcome and change in PGA-OA as the anchor was used to establish MWPC for WOMAC domains., Results: In the 3 studies, there were 688, 844, and 2948 subjects available for analyses, respectively. Analysis showed that a linear relationship between changes in WOMAC domains and changes in PGA-OA was supported and justified. Moreover, the relationships between these changes were very similar for 2 trials and close for the third. The estimated MWPC for the 3 WOMAC domains were from 0.84-1.16 (0-10 numerical rating scale) and from 12.50-16.23%, depending on study and domain, that corresponded to a 1-category change on PGA-OA. For a 2-category change those values were from 1.68-2.31 and from 25.01-32.46%, respectively., Conclusion: These results establish MWPCs for WOMAC domains, at the individual patient level, for patients with moderate-to-severe OA of the hip or knee.

Background: Several pharmaceutical treatments for chronic pain caused by osteoarthritis (OA) and chronic low back pain (CLBP) are available or currently under development, each associated with different adverse events (AEs) and efficacy profiles. It is therefore important to understand what trade-offs patients are willing to make when choosing between treatments., Methods: A discrete-choice experiment (DCE) was conducted with 437 adults with chronic pain caused by OA and/or CLBP. Respondents were presented with a series of scenarios and asked to choose between pairs of hypothetical treatments, each defined by six attributes: level of symptom control; risks of heart attack, rapidly progressive osteoarthritis and dependency; frequency and mode of administration and cost. Attributes were based on known profiles of oral nonsteroidal anti-inflammatory drugs, opioids and injected nerve growth factor inhibitors, the last of which were under clinical development at the time of the study. Data were analysed using a latent class (LC) model to explore preference heterogeneity., Results: Overall, respondents considered improving symptom control and reducing risk of physical dependency to be the most important attributes. The LC analysis identified four participant classes: an 'efficacy-focused' class (33.7%), a 'cost-averse' class (29.4%), a 'physical-dependence-averse' class (19.6%) and a 'needle-averse' class (17.3%). Subgroup membership was incompletely predicted by participant age and their responses to comprehension questions., Conclusions: Preference heterogeneity across respondents indicates a need for a personalized approach to offering treatment options. Symptom improvement, cost, physical dependence and route of administration might be important to different patients., Significance: Multiple treatment options that differ substantially in terms of efficacy and adverse events are available for the management of chronic pain. With a growing emphasis on a patient-centred care model that incorporates patients' priorities and values into treatment decisions, there is a need to understand how individuals with chronic musculoskeletal pain balance the benefits and risks of treatment and how treatment priorities vary among individuals. This study was designed to identify patient preferences for different characteristics of treatments for the management of chronic pain and to investigate how preferences differ among respondents., (© 2021 Pfizer Inc.

Background: Moderate-to-severe atopic dermatitis (AD) is inadequately controlled with current treatments for many patients. Abrocitinib is an oral Janus kinase 1 selective inhibitor under investigation for the treatment of AD., Objective: The aim of the study was to evaluate patient-reported outcomes in a phase 2b study of abrocitinib in adults with moderate-to-severe AD inadequately controlled by topical therapy (NCT02780167)., Methods: Patients (N = 267) were randomly assigned 1:1:1:1:1 to 12-week, once-daily abrocitinib (200, 100, 30, 10 mg) or placebo. Patient-reported outcomes included pruritus numeric rating scale (average), Patient Global Assessment, Patient-Oriented Eczema Measure, Pruritus and Symptoms Assessment for AD, Dermatology Life Quality Index, and Hospital Anxiety and Depression Scale (HADS)., Results: Abrocitinib 200 or 100 mg resulted in significantly greater improvements from baseline versus placebo in peak pruritus numeric rating scale (by days 2 and 3, respectively), Patient-Oriented Eczema Measure, Pruritus and Symptoms Assessment for AD, Dermatology Life Quality Index, and HADS (200 mg only, by week 1 or 2), and proportions of the patients with Patient Global Assessment clear/almost clear with 2-point or greater improvement (by weeks 1 and 4, respectively) that continued through week 12 (except HADS)., Conclusions: Abrocitinib treatment resulted in rapid (2 days to 2 weeks) and persistent improvements in AD symptoms and impacts in moderate-to-severe disease., (Copyright © 2021 American Contact Dermatitis Society.

Background and Aims: Tofacitinib is an oral, small molecule Janus kinase [JAK] inhibitor that is being investigated for ulcerative colitis [UC]. We evaluated health-related quality of life [HRQoL] in tofacitinib UC Phase 3 studies., Methods: Patients ≥ 18 years old in OCTAVE Induction 1 [N = 598] and 2 [N = 541] with moderately to severely active UC were randomised [1:4] to placebo or tofacitinib 10 mg twice daily [BID] for 8 weeks. Subsequently, OCTAVE Sustain re-randomised [1:1:1] clinical responders [N = 593] from induction studies to placebo, tofacitinib 5 mg BID, or 10 mg BID, for 52 weeks. Inflammatory Bowel Disease Questionnaire [IBDQ] and SF-36v2® Health Survey [SF-36v2] assessed HRQoL., Results: In OCTAVE Induction 1 and 2, mean changes from baseline IBDQ were greater with tofacitinib 10 mg BID at Week 8 [28.9 and 31.5] versus placebo [15.4 and 17.2; p < 0.0001]; mean changes from baseline SF-36v2 Physical and Mental Component Summaries [PCS/MCS] were also greater with 10 mg BID [PCS: 6.8 and 6.8; MCS: 6.8 and 7.6] versus placebo [PCS: 2.5 and 4.6; MCS: 3.5 and 4.4; p < 0.01]. In OCTAVE Sustain atWeek 52, changes in IBDQ were maintained with tofacitinib 5 mg [-1.3] and 10 mg BID [0.6], and larger with placebo [-20.2; p < 0.0001]. Changes in SF-36v2 PCS/MCS were also maintained with 5 mg [PCS: 0.0; MCS: -1.0] and 10 mg BID [PCS: 0.3; MCS: 0.1] versus placebo [PCS: -5.2; MCS: -6.7; p < 0.0001] at Week 52 in OCTAVE Sustain., Conclusions: Tofacitinib 10 mg BID induction therapy significantly improved HRQoL versus placebo at Week 8. Improvements were maintained through 52 weeks' maintenance therapy with tofacitinib 5 mg and 10 mg BID., Clinicaltrials.gov Registration Numbers: NCT01465763, NCT01458951 and NCT01458574., (© European Crohn’s and Colitis Organisation (ECCO) 2017.)

Objective: To evaluate the impact of baseline hot flush frequency and severity on time to symptom improvement during treatment with conjugated estrogens/bazedoxifene (CE/BZA)., Methods: Data were pooled through week 12 from two randomized placebo-controlled trials (SMART-1 and SMART-2) of nonhysterectomized postmenopausal women with hot flushes treated with CE 0.45 mg/BZA 20 mg or CE 0.625 mg/BZA 20 mg. Time to transient and stable improvement (≥ 50% reduction in hot flush frequency/severity) was estimated using nonparametric models., Results: Transient improvement in hot flush frequency occurred earlier in women treated with CE 0.45 mg/BZA 20 mg with less frequent versus more frequent baseline hot flushes per day: median time to transient improvement was 2, 7, and 11 days for women with < 3, 3 to < 8, and ≥ 8 hot flushes per day at baseline, respectively (P = 0.0009). Transient improvement in severity occurred earlier for women with less severe versus more severe baseline hot flushes: median time to transient improvement was 2, 6, and 16 days for women with mild, moderate, and severe hot flushes at baseline, respectively (P < 0.0001). Stable improvement typically occurred 2 to 3 days after the transient event and was less influenced by baseline status. A similar pattern was observed with CE 0.625 mg/BZA 20 mg treatment, though improvement occurred a few days earlier than with CE 0.45 mg/BZA 20 mg., Conclusion: Women with more frequent/severe hot flushes take longer to achieve transient improvements with CE/BZA and should be encouraged to continue treatment, as it may take longer than a few weeks to achieve significant improvement.

Introduction: The 33-item Overactive Bladder questionnaire (OAB-q; 1-week recall version) has been psychometrically validated in middle-aged, generally healthy patients with overactive bladder. The present analysis was conducted to determine the psychometric validity of the OAB-q in medically complex elderly patients., Methods: OAB-q structure was evaluated using a second-order confirmatory factor analysis (CFA) model with five domains and one aggregated domain, using pooled data from two clinical trials (786 observations) for urgency urinary incontinence (UUI). Psychometric validity was evaluated with CFA, Cronbach coefficient α (CCA) for reliability, Spearman correlations for convergent validity, differences in OAB-q scores in relation to UUI severity and Patient Perception of Bladder Condition (PPBC) scores for known-groups validity, and effect size (ES) of differences in mean scores of OAB-q domains over time for treatment responsiveness., Results: Participants were predominantly female (82.2%) and white (85.9%); mean age was 75.0 years. The second-order CFA was confirmed with a Bentler's comparative fit index of 0.90, t values for path coefficients of >1.96, and standardized path coefficients of >0.40. OAB-q domains demonstrated good internal consistency (CCA >0.7). Convergent validity was supported by moderate correlations (0.4-0.7) between OAB-q domain and PPBC scores. Significant differences in OAB-q domain scores between groups with different symptom severity established known-groups validity. Significant changes in mean OAB-q scores from baseline to week 12 with moderate-to-large ES (0.50-0.80) demonstrated treatment responsiveness., Conclusions: The OAB-q demonstrates reliability, concurrent and discriminant validity, and responsiveness to treatment. The evidence shows that the OAB-q is psychometrically sound for use in medically complex elderly patients with overactive bladder.

Objective: In studies of the menopausal therapy, conjugated estrogens/bazedoxifene, breast pain and vaginal bleeding rates were comparable to placebo and lower than conjugated estrogens/medroxyprogesterone acetate (MPA). This post hoc analysis determined median time to occurrence of these events., Methods: Participants in phase 3 conjugated estrogens/bazedoxifene trials recorded breast pain and vaginal bleeding in daily diaries. Median time to first incident was determined in women taking conjugated estrogens 0.45 mg/bazedoxifene 20 mg, conjugated estrogens 0.625 mg/bazedoxifene 20 mg, placebo, and conjugated estrogens 0.45 mg/MPA 1.5 mg (active control in Selective estrogens, Menopause, And Response to Therapy [SMART]-5 trial). We included on-treatment data (12 weeks-2 years) in healthy postmenopausal women (SMART-1), those seeking treatment for menopausal symptoms (SMART-5), and those with moderate/severe vasomotor symptoms (SMART-2). Analyses were performed using SAS Proc Lifetest., Results: With conjugated estrogens/MPA as comparator, median time to breast pain was 299 days for conjugated estrogens/MPA, 353 for placebo, and more than 365 (median not reached) for conjugated estrogens 0.45 mg/bazedoxifene 20 mg and conjugated estrogens 0.625 mg/bazedoxifene 20 mg. Median time to vaginal bleeding was 314, 341, 357, and 362 days, respectively. Breast pain and vaginal bleeding survival curves were not significantly different for conjugated estrogens/bazedoxifene and placebo in any study, but were (P < 0.0001) when conjugated estrogens/MPA was added to the sample in SMART-5., Conclusions: The time course of breast pain and vaginal bleeding with conjugated estrogens/bazedoxifene was similar to that of placebo during treatment for up to 2 years. Events occurred significantly earlier with conjugated estrogens/MPA versus conjugated estrogens/bazedoxifene or placebo.

Objective: This post hoc analysis estimates time to transient and stable reductions in hot flush frequency in postmenopausal women using conjugated estrogens/bazedoxifene., Methods: In the 12-week Selective estrogens, Menopause, And Response to Therapy (SMART)-2 trial of conjugated estrogens/bazedoxifene 0.45 mg/20 mg and 0.625 mg/20 mg, women with at least seven moderate/severe hot flushes per day or 50 per week at screening recorded frequency of moderate/severe hot flushes in diaries. Nonparametric models and SAS Proc Lifetest were used to estimate median times to various degrees of transient reductions (first day with improvement) and stable reductions (first day with improvement maintained through study's end) in hot flush frequency., Results: Treatment produced transient hot flush reductions of 40% to 100% and stable reductions of 30% to 100% significantly faster than placebo. Median time to a transient 50% reduction was 8 days for conjugated estrogens/bazedoxifene 0.45 mg/20 mg, 9.5 for 0.625 mg/20 mg, and 10 for placebo; median time to a stable 50% reduction was 9, 10, and 38 days. Median time to a transient 90% reduction was 32 and 22.5 days for 0.45 mg/20 mg and 0.625 mg/20 mg, and median time to a stable 90% reduction was 83 and 29 days, respectively; median times to transient/stable 90% reductions were not reached during the 12-week study in the placebo group., Conclusions: Although not all women using conjugated estrogens/bazedoxifene achieve permanent elimination of hot flushes, the frequency is likely to be substantially reduced during the first week to month. Women can expect approximately 50% reduction in hot flush frequency after about 8 to 10 days, and sustained improvement with continued treatment.

Introduction: Patient-reported outcomes are a valuable tool used to gauge treatment satisfaction in different conditions, including erectile dysfunction (ED)., Aim: To use person-item maps to quantify barriers to improvement of treatment satisfaction in men with ED., Methods: Men 18 to 65 years old with documented ED received sildenafil 50 mg, sildenafil 100 mg, or placebo for 8 weeks in a double-blinded manner. Post hoc analyses were conducted on Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) data (11 items rating treatment satisfaction; each item score range = 0-4)., Main Outcome Measures: Person-item maps were developed based on Rasch models. To quantify barriers to improvement of treatment satisfaction, responses to the 11 items of the EDITS questionnaire were dichotomized to indicate improvement (responses of 3 or 4 were combined to a score of 1) vs no change or worsening (responses of 0, 1, or 2 were combined to a score of 0)., Results: Analyses were conducted using data from 278 men who completed the EDITS questionnaire at the end of double-blinded treatment. The person-item map indicated that EDITS item 4 (ease of use of treatment) was the easiest barrier to overcome, whereas the most difficult barrier to improvement of treatment satisfaction was EDITS item 2 (degree to which treatment met expectations). Most men in the sildenafil 100-mg group endorsed most EDITS items, consistent with substantial improvement. The sildenafil 50-mg group was similar, but with smaller frequencies for endorsing improvement of the more difficult EDITS items. In contrast, men receiving placebo endorsed mainly the easiest EDITS items, with only a small number of men endorsing the difficult items., Conclusion: A person-item map is a useful means for quantifying barriers to improvement of treatment satisfaction represented by EDITS items in patients with ED., (Copyright © 2016 International Society for Sexual Medicine.

Objective: The aim of the study was to examine whether physicians who are better informed about large, published hormone therapy (HT) trials (eg, the Women's Health Initiative) are more likely to prescribe HT for menopausal symptoms., Methods: US obstetricians/gynecologists and primary care physicians completed a 15- to 20-minute Internet-based survey. Knowledge was assessed via nine true-false statements about HT trials (range: 0-9). Prescribing practices were assessed via six case studies with a seven-point response scale of "extremely unlikely" to "extremely likely" in relation to treatment options (range: 6-42). The primary analysis examined the correlation between HT trial knowledge and likelihood of prescribing HT. Secondary analyses gauged knowledge and prescribing practices based on practice type, sex, and years in practice., Results: Among 501 physicians who completed the survey (representing 10.7% of those invited; median age: 51.0 y; female: 26.9%; obstetricians/gynecologists: 49.9%; median 19.0 y in practice), HT knowledge (mean [SD] 3.8 [2.3]), and prescribing (mean [SD] 24.5 [5.6]) exhibited a statistically significant, moderate positive correlation (0.30; 95% CI, 0.21-0.37; P < 0.0001). Obstetricians/gynecologists were significantly (P < 0.0001) more knowledgeable and more likely to prescribe HT than primary care physicians. Male physicians were more likely (P < 0.05) to prescribe HT but not more knowledgeable about it than female physicians. Knowledge (but not likelihood of prescribing) significantly increased as a function of years in practice., Conclusions: Physicians who are more knowledgeable about large, published HT trials are more likely to prescribe HT for menopausal symptoms.

Objective: Compare the efficacy of bazedoxifene with oral bisphosphonates for reduction of vertebral fracture risk in postmenopausal osteoporotic (PMO) women and in higher-risk patients based on evidence from randomized controlled trials (RCTs)., Methods: Eight RCTs assessing vertebral fracture risk reduction with oral bisphosphonates (n = 7) or bazedoxifene (n = 1) were identified by a systematic literature review. Individual study results were pooled in a network meta-analysis (NMA) to indirectly compare treatment effects for overall PMO women and a higher-risk subgroup (FRAX ≥ 20%). Three sets of NMA analyses were conducted: aggregate data (AD) from the bisphosphonate RCTs and bazedoxifene RCT for the full population or the FRAX ≥20% subgroup (NMA AD); bisphosphonate AD and bazedoxifene AD from each FRAX subgroup adjusted for baseline risk (NMA AD meta-regression); and bisphosphonate AD and bazedoxifene individual patient data (IPD) adjusted for baseline risk/FRAX (NMA AD/IPD meta-regression)., Results: For the overall population, bisphosphonates had lower fracture risks versus bazedoxifene although there is considerable uncertainty in supporting one intervention over another. The relative risk reduction (RRR) for bazedoxifene was -0.23 (95% CrI: -1.11, 0.27) versus ibandronate, -0.17 (-0.76, 0.22) versus alendronate, and -0.06 (-0.62, 0.30) versus risedronate. RESULTS from the meta-regression analyses were similar. For the FRAX ≥20% population, estimated fracture rates with bazedoxifene were lower than with bisphosphonates, but again the uncertainty limits strong interpretation. The RRR for bazedoxifene was 0.51 (-0.31, 0.83) versus ibandronate, 0.53 (-0.18, 0.83) versus alendronate, and 0.57 (-0.07, 0.85) versus risedronate. The meta-regression analyses showed comparable findings., Conclusion: The analyses only considered vertebral fractures for oral bisphosphonates versus bazedoxifene, and IPD was available only for bazedoxifene. In light of this, bazedoxifene is comparable to bisphosphonates in the overall PMO population and at least as effective as bisphosphonates for preventing vertebral fractures among higher-risk PMO patients. The findings suggest bazedoxifene performs better in higher-risk PMO than in the overall PMO.

Purpose: To introduce an application of area-under-the-curve (AUC) that can enrich interpretation of response analysis and illustrate this method on sleep quality scores in patients with fibromyalgia., Methods: Data were from a 14-week, randomized trial conducted in 750 patients with fibromyalgia treated with placebo or pregabalin (300, 450, or 600 mg/day); sleep quality was assessed daily by the patient using an 11-point numeric rating scale., Results: Response profiles were implemented for responders who improved (or stayed the same) numerically in sleep quality scores from baseline to week 14 and, separately, for non-responders who worsened (numerically less favorable scores at week 14). Differences between pregabalin and placebo were assessed using an AUC analysis. Improvement in sleep quality was significantly better with pregabalin and can be interpreted as if pregabalin responders improved by 10.8% (300 mg), 14.7% (450 mg), and 19.0% (600 mg) above the placebo responders. Conversely, decrement in sleep quality was worse with placebo and can be interpreted as if placebo non-responders worsened by 3.6% (300 mg), 2.9% (450 mg), and 3.9% (600 mg) over pregabalin non-responders., Conclusions: The application of an AUC analysis to response profiles for responders and non-responders can enrich the interpretation of sleep quality scores in patients with fibromyalgia. The method can be applied more generally to facilitate and enhance the interpretation of treatment differences on outcomes.
