Score reproducibility is an important measurement property of fit-for-purpose patient-reported outcome (PRO) measures. It is commonly assessed via test-retest reliability, and best evaluated with a stable participant sample, which can be challenging to identify in diseases with highly variable symptoms. To provide empirical evidence comparing the retrospective (patient global impression of change [PGIC]) and current state (patient global impression of severity [PGIS]) approaches to identifying a stable subgroup for test-retest analyses, 3 PRO Consortium working groups collected data using both items as anchor measures.The PGIS was completed on Day 1 and Day 8 + 3 for the depression and non-small cell lung cancer (NSCLC) studies, and daily for the asthma study and compared between Day 3 and 10. The PGIC was completed on the final day in each study. Scores were compared using an intraclass correlation coefficient (ICC) for participants who reported "no change" between timepoints for each anchor.ICCs using the PGIS "no change" group were higher for depression (0.84 vs. 0.74), nighttime asthma (0.95 vs. 0.53) and daytime asthma (0.86 vs. 0.68) compared to the PGIC "no change" group. ICCs were similar for NSCLC (PGIS: 0.87; PGIC: 0.85).When considering anchor measures to identify a stable subgroup for test-retest reliability analyses, current state anchors perform better than retrospective anchors. Researchers should carefully consider the type of anchor selected, the time period covered, and should ensure anchor content is consistent with the target measure concept, as well as inclusion of both current and retrospective anchor measures.

ObjectiveSLE and lupus nephritis (LN) have significant impacts on the health-related quality of life of patients living with the condition, which are important to capture from the patient’s perspective using patient-reported outcomes (PROs). The objectives of this study were to evaluate the content validity of PROs commonly used in SLE and LN (36-Item Short Form Health Survey (SF-36), Functional Assessment of Chronic Illness Therapy–Fatigue (FACIT-F) and Lupus Quality of Life (LupusQoL), as well as novel PRO symptom severity items measuring skin rash, joint pain, joint stiffness and swelling of the legs and/or feet, in both populations.MethodsQualitative, semi-structured, cognitive interviews were conducted with 48 participants (SLE=28, LN=20). Understanding and relevance of symptom and impact PRO concepts from existing PROs were assessed, alongside novel PRO symptom severity items with different recall periods (24 hours vs 7 days) and response scales (Numerical Rating Scale (NRS) vs Verbal Rating Scale). Interviews were conducted in multiple rounds to allow for modifications to the novel PRO items. Analysis of verbatim interview transcripts was performed.ResultsSymptom and impact concepts assessed by the SF-36, FACIT-F, and LupusQoL were well understood by both participants with SLE and LN (≥90.0%), with most considered relevant by over half of the participants asked (≥51.9%). All participants asked (100%) understood the novel PRO symptom severity items, and the majority (≥90.0%) considered the symptoms relevant. Minor modifications to the novel PRO items were made between rounds to improve clarity based on participant feedback. The selected 7-day recall period and NRS in the final iteration of the PRO items were understood and relevant. No differences in interview findings between the SLE and LN samples were identified.ConclusionsFindings provide evidence of content validity for concepts assessed by the SF-36, FACIT-F, LupusQoL and the novel PRO symptom severity items, supporting use of these PROs to comprehensively assess disease impact in future SLE and LN clinical trials.

Background The lower-risk (low and intermediate-1 risk based on IPSS) myelodysplastic syndrome (MDS) has a negative impact on patients’ health-related quality of life (HRQoL). Patient Reported Outcomes (PROs) instruments, which are used to collect patients’ HRQoL data, should have established content validity in the target population to ensure that the instrument is comprehensive and comprehensible. The present study was conducted to evaluate the content validity of the Quality of Life in Myelodysplasia Scale (QUALMS) and the Functional Assessment of Cancer Therapy-Anemia (FACT-An) PRO instruments in patients with lower-risk MDS. Methods In this cross-sectional, qualitative study, 16 patients aged ≥18 years with lower-risk MDS, who were RBC transfusion dependent, literate and fluent in US-English were interviewed. Interviews were semi-structured comprising of two parts: concept elicitation (CE) explored symptoms and impacts important to patients, and cognitive debriefing (CD) assessed understanding and relevance of the QUALMS and FACT-An. A conceptual model was developed, which was used to map the concepts that emerged during CE onto the QUALMS and FACT-An to assess concept coverage and suitability of the instruments. Results The median age of participants was 67.5 years (range: 51–91), with half being female (n = 8). Nine (56.2%) participants had intermediate-1-risk MDS and 10 (62.5%) were relapsed or refractory to erythropoiesis-stimulating agent treatment. Fatigue/tiredness (100.0%), shortness of breath (87.5%), weakness (81.2%), and low energy (75.0%) were reported most commonly and were the most bothersome symptoms as well. Of seven high-level HRQoL domains identified, activities of daily living (n = 16, 100.0%), physical functioning (n = 15, 93.8%), emotional wellbeing (n = 13, 81.3%), social functioning (n = 12, 75.0%), sleep disturbance (n = 9, 56.3%), and impact on work (n = 9, 56.3%) were the most commonly reported. For CD, the QUALMS and FACT-An were found to be mostly relevant and very well understood; response options were easy to use, and recall period was appropriate. Conclusion Both QUALMS and FACT-An demonstrated a strong face and content validity in patients with lower-risk MDS, suggesting that these instruments are appropriate for assessing HRQoL in this population.

Expectations relating to treatment and survival, and factors influencing treatment decisions are not well understood in adult patients with acute myeloid leukemia. This study analyzed combined findings from a targeted literature review with patient-reported information shared on YouTube to further understand patient perspectives in hematologic cancers and, in particular, acute myeloid leukemia. The targeted literature review included articles concerning patient (aged ≥ 18 years) experiences or perspectives in acute myeloid leukemia or other hematologic cancers. YouTube video selection criteria included patients (aged ≥ 60 years) with self-reported acute myeloid leukemia. In total, 26 articles (13 acute myeloid leukemia–specific and 14 other hematologic cancers, with one relevant to both populations) and 28 videos pertaining to ten unique patients/caregivers were identified. Key concepts reported by patients included the perceived value of survival for achieving personal and/or life milestones, the emotional/psychological distress of their diagnosis, and the uncertainties about life expectancy/prognosis. Effective therapies that could potentially delay progression and extend life were of great importance to patients; however, these were considered in terms of quality-of-life impact and disruption to daily life. Many patients expressed concerns regarding the lack of treatment options, the possibility of side effects, and how their diagnosis and treatment would affect relationships, daily lives, and ability to complete certain tasks. Both data sources yielded valuable and rich information on the patient experience and perceptions of hematologic cancers, in particular for acute myeloid leukemia, and its treatments. Further understanding of these insights could aid discussions between clinicians, patients, and their caregivers regarding treatment decisions, highlight outcomes of importance to patients in clinical studies, and ultimately, inform patient-focused drug development and evaluation.

Background The Endometriosis Symptom Diary (ESD) and Endometriosis Impact Scale (EIS) are patient-reported outcome measures developed to evaluate efficacy in clinical trials and clinical practice. The ESD is a daily electronic diary assessing symptom severity; the EIS is a weekly electronic diary assessing symptom impact. This study explored the importance of symptoms (ESD items) and impacts (EIS domains), perspectives on scoring algorithms, and clinically important difference (CID) thresholds to inform clinical trial score interpretation. Methods Endometriosis patients in Germany (n = 8) and the US (n = 17), and expert clinicians (n = 4) in Germany, the US, Spain, and Finland participated in semi-structured qualitative interviews comprising structured tasks. Interview transcripts were analyzed using thematic analysis techniques. Results Quality and severity of endometriosis-associated pelvic pain varied considerably among patients; some experienced pelvic pain daily, others during menstrual bleeding (dysmenorrhea) only. Patients and clinicians ranked “worst pelvic pain” as the most meaningful pain concept assessed by the ESD, followed by constant and short-term pelvic pain. Preferences for summarizing daily pain scores over the 28-day menstrual cycle depended on individuals’ experience of pain: patients experiencing pain daily preferred scores summarizing data for all 28 days; patients primarily experiencing pain during selected days, and their treating clinicians preferred scores based on the most severe pain days. Initial CID exploration for the “worst pelvic pain” 0–10 numerical rating scale (0–10 NRS) revealed that, for most patients, a 2- or 3-point reduction was considered meaningful, depending on baseline severity. Patients and clinicians ranked “emotional well-being” and “limitations in physical activities” as the most important EIS domains. Conclusions This study informs the use of the ESD and EIS as clinically relevant measures of endometriosis symptoms and their impact. Findings from the ESD highlight the importance of individual-patient assessment of pain experience and identify “worst pelvic pain” as the most meaningful symptom assessed. Aggregating scores over the 28-day menstrual cycle may inform meaningful endpoints for clinical trials. Diverse EIS concepts (e.g. impact on emotional well-being and physical activities) are meaningful to patients and clinicians, emphasizing the importance of evaluating the impact on both to comprehensively assess treatment efficacy and decisions. Trial registration Not applicable. Qualitative, non-interventional study; registration not required.

Background: Long-chain fatty acid oxidation disorders (LC-FAOD) are a group of rare autosomal-recessive genetic disorders characterized by metabolic deficiencies in which the body is unable to convert long-chain fatty acids into energy. To date, however, there is limited understanding of the patient experience of LC-FAOD. Methods: The symptoms, observable signs, and quality of life (QoL) impacts associated with LC-FAOD were explored via a focus group ( n = 8) and semi-structured interviews ( n = 6) with patients and caregivers of patients with LC-FAOD, and interviews ( n = 4) with expert clinicians. Data were analyzed via thematic analysis and summarized in a conceptual model. Results: Participants reported a wide range of signs and symptoms associated with LC-FAOD, broadly categorized as musculoskeletal, endocrine/nutritional/metabolic, neurological, gastrointestinal/digestive, sensory, cardiovascular, respiratory, urological, and constitutional. LC-FAOD were reported to have a significant impact on various aspects of patients’ lives including physical functioning, participation in daily activities, emotional/psychological wellbeing, and social functioning. Lifestyle modifications (such as diet and exercise restrictions) were necessary because of the condition. Symptoms were typically episodic in presentation often arising or exacerbated during catabolic conditions such as prolonged exercise, fasting, physiological stress, and illness/infection. Symptoms were also commonly reported to lead to emergency room visits, hospitalization, and clinical complications. Conclusion: LC-FAOD have a considerable impact on patients’ lives. There is a high degree of concordance in the signs, symptoms, and impacts of LC-FAOD reported by patients, caregivers, and clinicians; however, there were many symptoms and impacts that were only reported by patients and caregivers, thus demonstrating that insights from patient/caregiver experience data are integral for informing medical product development and facilitating patient-centered care.

Objectives To qualitatively explore patient experiences of severe, recurrent, bilateral nasal polyps (NP). Methods A targeted literature review of published qualitative studies and online blogs describing patient experiences of NP was conducted. Semistructured concept elicitation interviews were conducted in the United States and Germany with participants ≥18 years with severe, recurrent, bilateral NP to explore their symptom experience and impacts on health-related quality of life (HRQoL; NCT03221192 ). A subset of 10 participants reported symptoms and impacts using a smartphone or tablet application (app) over a 10-day period. Results A paucity of qualitative evidence regarding patient experience of NP was identified from the literature or blog review. Twenty-seven participant interviews were conducted. Thirty-six symptoms were identified, including 7 primary symptoms (nasal congestion [n = 27 of 27], breathing difficulties [n = 27 of 27], postnasal drip [n = 25 of 27], runny nose [n = 24 of 27], head/facial pressure [n = 23 of 27], loss of smell [n = 23 of 27], loss of taste [n = 22 of 27]) and 29 secondary symptoms (the most common were mucus/catarrh and nose bleeds [both n = 20 of 27]). Most symptoms were reported to vary both within and between days. Sixty impacts of severe NP were reported, including impacts on sleep (n = 22 of 27), physical functioning (n = 21 of 27), activities of daily living (n = 21 of 27), emotional well-being (n = 27 of 27), treatment (n = 23 of 27), social life (n = 26 of 27), and work (n = 19 of 27). Symptoms/impacts reported using the app were consistent with interview findings, although new symptoms were identified (ear pain, throat pain, nasal scabs, and nasal burning). These results supported the development of a conceptual model outlining concepts related to symptoms, impacts, and treatment of NP. Conclusions Severe, recurrent, bilateral NP are associated with a range of symptoms that have significant detrimental impact on HRQoL.

Introduction Recent studies suggest that docetaxel plus androgen deprivation therapy can prolong survival among men with metastatic hormone-sensitive prostate cancer (mHSPC). However, as a cytotoxic therapy, there is a need to understand the experiences of men with mHSPC receiving docetaxel and their carers in a real-world setting. Methods During phase 1, semi-structured qualitative interviews were conducted with men with mHSPC (n = 31) and their carers (n = 14) in Europe to elicit in-depth data concerning their experiences with docetaxel. Eighteen men were also asked to record their experiences in a diary for 7 days. During phase 2, men with mHSPC (n = 161) and carers of men with mHSPC (n = 135) completed an online survey comprising self-report questionnaires including the Cancer Therapy Satisfaction Questionnaire, Brief Fatigue Inventory, Functional Assessment of Cancer Therapy-Prostate, EuroQol-5-Dimensions and the Burden Scale for Family Caregivers (carers only). Results At the outset of therapy, men reported a willingness to take docetaxel to prolong their life, despite being fearful of the potential side effects and impacts on their daily lives. Patient and carer experiences were generally consistent with pre-treatment expectations. However, variations in individual experiences and their ability to tolerate side effects were evident. Fatigue emerged as a prominent symptom with the majority (n = 98, 60.9%) of men reporting experiencing moderate-severe fatigue in the past 24 h. Participant ratings of fatigue were strongly correlated with health-related quality of life (r = − 0.82). Nausea, diarrhoea and sore mouth were also among the most bothersome symptoms for participants. Conclusions Findings from this study highlight that real-world experience of docetaxel may differ from that observed in clinical trials and that care must be taken to ensure that treatment options are tailored to the needs of individual patients to promote not only how long patients survive but also the quality of that survival.

Clinical studies have demonstrated the benefits of abiraterone acetate + prednisone (AAP) and enzalutamide (ENZ) in significantly improving survival among metastatic castration-resistant prostate cancer (mCRPC) patients. However, evidence regarding patient's real-world experience, particularly with respect to fatigue, treatment satisfaction and health-related quality of life (HRQoL) is limited. Interviews were initially conducted with patients (n = 38) and carers (n = 12) to elicit qualitative data regarding their experiences. Findings informed the design of a quantitative, multinational online survey of mCRPC patients (n = 152) receiving AAP or ENZ. Participants completed validated questionnaires assessing fatigue (Brief Fatigue Inventory), treatment satisfaction (Cancer Therapy Satisfaction Questionnaire) and HRQoL (EuroQol-5-Dimensions). Results indicated that patients were generally satisfied with these therapies, more specifically with reductions in prostate-specific antigen levels and extended survival. Fatigue was commonly linked to poor HRQoL and responses indicated that significantly fewer patients in the AAP group reported feeling usually tired or fatigued in the last week compared to the ENZ group (33% vs. 55%, p = 0.006 respectively). Findings highlight the benefit of AAP and ENZ in promoting the "quality" of extended survival. That fatigue was lower among patients receiving AAP may be important for informing treatment decisions. Further research is needed to gain deeper insights.

The primary objective of this review is to develop a conceptual model for Crohn's disease (CD) outlining the disease burden for patients, healthcare systems and wider society, as reported in the scientific literature. A search was conducted using MEDLINE, PsycINFO, EconLit, Health Economic Evaluation Database and Centre for Reviews and Dissemination databases. Patient-reported outcome (PRO) measures widely used in CD were reviewed according to the US FDA PRO Guidance for Industry. The resulting conceptual model highlights the characterization of CD by gastrointestinal disturbances, extra-intestinal and systemic symptoms. These symptoms impact physical functioning, ability to complete daily activities, emotional wellbeing, social functioning, sexual functioning and ability to work. Gaps in conceptual coverage and evidence of reliability and validity for some PRO measures were noted. Review findings also highlight the substantial direct and indirect costs associated with CD. Evidence from the literature confirms the substantial burden of CD to patients and wider society; however, future research is still needed to further understand burden from the perspective of patients and to accurately understand the economic burden of disease. Challenges with existing PRO measures also suggest the need for future research to refine or develop new measures.

Background Patient-reported outcome (PRO) instruments are important tools for monitoring disease activity and response to treatment in clinical trials and clinical practice. In recent years, there have been movements away from traditional pen-and-paper PROs towards electronic administration. When using electronic PROs (ePROs), evidence that respondents complete ePROs in a similar way to their paper counterparts provides assurance that the two modes of administration are comparable or equivalent. The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 item (EORTC QLQ-C30) and associated disease-specific modules are among the most widely used PROs in oncology. Although studies have evaluated the comparability and equivalence of electronic and original paper versions of the EORTC QLQ-C30, no such studies have been conducted to date for the head and neck cancer specific module (EORTC QLQ-H&N35). Objective This study aimed to qualitatively assess the comparability of paper and electronic versions of the EORTC QLQ-H&N35. Methods Ten head and neck cancer patients in the United States underwent structured cognitive debriefing and usability interviews. An open randomized crossover design was used in which participants completed the two modes of administration allocated in a randomized order. Using a “think-aloud” process, participants were asked to speak their thoughts aloud while completing the EORTC QLQ-H&N35. They were thoroughly debriefed on their responses to determine consistency in interpretation and cognitive process when completing the instrument in both paper and electronic format. Results Participants reported that the EORTC QLQ-H&N35 demonstrated excellent qualitative comparability between modes of administration. The proportion of noncomparable responses (ie, where the thought process used by participants for selecting responses appeared to be different) observed in the study was low (11/350 response pairs [35 items x 10 participants]; 3.1%). Evidence of noncomparability was observed for 9 of the 35 items of the EORTC QLQ-H&N35 and in no more than 2 participants per item. In addition, there were no apparent differences in level of comparability between individual participants or between modes of administration. Conclusions Mode of administration does not affect participants’ response to, or interpretation of, items in the EORTC QLQ-H&N35. The findings from this study add to the existing evidence supporting the use of electronic versions of the EORTC instruments when migrated to electronic platforms according to best practice guidelines.

Background Herpes zoster (HZ) is a painful condition that can have a substantial negative impact on patients’ lives. However, UK-specific data on the debilitating impact of HZ, in terms of patients’ experience of pain and impairments in Health-Related Quality of Life (HRQoL) are limited. The Zoster Quality of Life (ZQOL) study, a large-scale UK cross-sectional study, was conducted to quantify the burden of HZ in UK patients. Methods A total of 229 HZ patients aged 50 years or over were recruited from primary and secondary/tertiary care centres throughout the UK. Patients completed a battery of validated questionnaires, including the Zoster Brief Pain Inventory (ZBPI), the Medical Outcomes Study Short-Form 36 (SF-36) and the EuroQol-5 Dimensions (EQ-5D) on initial presentation to the doctor and again 7–14 days later. At follow-up patients also completed the Treatment Satisfaction with Medication (TSQM) questionnaire. Where available, mean questionnaire scores in the HZ population were compared to scores for age-matched norms to investigate the burden associated with HZ. Results Pain was prominent among patients, with 57.9% at the initial study visit reporting pain in the preceding 24 hours at levels typically considered to have a significant impact on HRQoL (i.e. ZBPI worst pain ≥ 5). This was reflected in SF-36 and EQ-5D scores that were significantly lower for patients when compared to age-matched norms (p

Treatment of iron overload using deferoxamine (DFO) is associated with significant deficits in patients' health-related quality of life (HRQOL) and low treatment satisfaction. The current article presents patient-reported HRQOL, satisfaction, adherence, and persistence data fromβ-thalassemia (n=274) and myelodysplastic syndrome (MDS) patients (n=168) patients participating in the Evaluation of Patients' Iron Chelation with Exjade (EPIC) study (NCT00171821); a large-scale 1-year, phase IIIb study investigating the efficacy and safety of the once-daily oral iron chelator, deferasirox. HRQOL and satisfaction, adherence, and persistence to iron chelation therapy (ICT) data were collected at baseline and end of study using the Medical Outcomes Short-Form 36-item Health Survey (SF-36v2) and the Satisfaction with ICT Questionnaire (SICT). Compared to age-matched norms,β-thalassemia and MDS patients reported lower SF-36 domain scores at baseline. Low levels of treatment satisfaction, adherence, and persistence were also observed. HRQOL improved following treatment with deferasirox, particularly amongβ-thalassemia patients. Furthermore, patients reported high levels of satisfaction with deferasirox at end of study and greater ICT adherence, and persistence. Findings suggest deferasirox improves HRQOL, treatment satisfaction, adherence, and persistence with ICT inβ-thalassemia and MDS patients. Improving such outcomes is an important long-term goal for patients with iron overload.

Background Post-herpetic neuralgia (PHN) is the most common complication of herpes zoster (shingles). As a chronic condition, PHN can have a substantial adverse impact on patients’ lives. However, UK-specific data concerning the burden of PHN on individual patients, healthcare systems and wider society, are lacking. As the first UK-wide cross-sectional study of its kind, The Zoster Quality of Life (ZQOL) study was designed to address these concerns. Methods Patients (n = 152) with a confirmed diagnosis of PHN (defined as pain persisting ≥ 3 months following rash onset) and aged ≥50 years were recruited from primary and secondary/tertiary care centres throughout the UK. All patients completed validated questionnaires, including the Zoster Brief Pain Inventory (ZBPI), the Medical Outcomes Study Short-Form 36 (SF-36), the EuroQol-5 Dimensions (EQ-5D) and the Treatment Satisfaction with Medication (TSQM) questionnaire. Where available, mean patient population scores on these questionnaires were compared to scores derived from age-matched normative samples to quantify the burden associated with PHN. Results Despite numerous consultations with healthcare professionals and receiving multiple medications for the management of their PHN, the majority of patients reported being in pain ‘most of the time’ or ‘all of the time’. A total of 59.9% (n = 91) of all PHN patients reported pain in the preceding 24 hours to assessment at levels (ZBPI worst pain ≥ 5) typically considered to have a significant impact on Health Related Quality of Life (HRQoL). Accordingly, scores for SF-36 and EQ-5D indicated significant deficits in HRQoL among PHN patients compared to age-matched norms (p

Abstract 2486 Poster Board II-463 Introduction: Iron chelation therapy (ICT) is essential in removing excess iron deposited in body organs, ultimately preventing organ failure and extending the lives of patients (pts) with transfusion-dependent hematological disorders such as β-thalassemia. Conventional ICT (deferoxamine, Desferal®, DFO) requires a burdensome regimen (subcutaneous delivery 5–7 times a week) that has been shown to negatively impact pts' health-related quality of life (HRQL) and adherence to therapy. Adherence to ICT affects survival and therefore a well-tolerated and effective ICT regimen is required. The once-daily oral chelator, deferasirox (Exjade®) offers 24-hour ICT, 7 days a week and is potentially less burdensome to pts. Methods: As part of a larger single-arm, multicenter, open-label trial investigating the efficacy and safety of deferasirox (EPIC study), 217 β-thalassemia pts >16 years of age were included in this subanalysis. Findings reported here investigate differences in satisfaction, adherence and HRQoL following treatment with deferasirox, in β-thalassemia patients with prior experience of DFO monotherapy, or DFO in combination with deferiprone (Ferriprox®, L1). All pts were asked at baseline and week 52 (end of study [EOS]) to complete the 19-item Satisfaction with ICT questionnaire (SICT) and the 36-item Short Form health survey (SF-36). Mean change scores between baseline and EOS on the four domains of the SICT (Perceived Effectiveness of ICT, Side Effects of ICT, Acceptance of ICT, and Burden of ICT) and the eight domains (Physical Functioning, Role-Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role-Emotional, and Mental Health) and two summary scores (Physical and Mental Component Scores) of the SF-36 were calculated for patients who completed the respective instruments at both timepoints. Higher scores on the SICT and SF-36 represent greater HRQL, satisfaction with, and adherence to treatment. Adherence to deferasirox was assessed by two SICT items asking pts how often they thought about stopping their ICT, and how often they took their ICT exactly as directed by their doctor. Results: 217 β-thalassemia pts were recruited (mean age 30.6 ± 7.7); 42.9% (n = 93) male, 57.1% (n = 124) female. Of 216 pts with prior history of ICT, 62.0% (n=134) had prior DFO monotherapy and 37.0% (n=80) had prior DFO in combination with L1 (2 patients had prior LI monotherapy; not included in this analysis due to the small patient number). SICT and SF-36 mean-change domain scores were based on patients who completed questionnaires at baseline and EOS (SICT: 105 DFO and 46 DFO+L1 pts; SF-36: 90 DFO and 42 DFO+L1 pts). Significant improvements (p Conclusions: β-thalassemia pts with prior history of ICT (DFO monotherapy or DFO+L1) demonstrated improved satisfaction and adherence to ICT following treatment with deferasirox. Improvements in HRQL were also observed and were generally greater in pts previously treated with DFO monotherapy compared with pts who previously received DFO+L1 combination therapy.

Introduction: Iron chelation therapy (ICT) is essential in removing excess iron deposited in body organs, ultimately preventing organ failure and extending the lives of patients (pts) with transfusion-dependent hematological disorders such as β-thalassemia and myelodysplastic syndromes (MDS). As a life-long treatment, traditional ICT (deferoxamine, Desferal®, DFO) is based on a burdensome regimen (subcutaneous delivery 5–7 times a week) that has been shown to negatively impact on pts’ health-related quality of life (HRQoL). The oral chelator deferasirox (Exjade®) is less burdensome to pts offering 24-hour ICT, 7 days a week. Methods: This substudy was part of a single arm, multicenter, 1-year open-label trial (the EPIC study) to investigate the efficacy/safety of deferasirox. The first 558 pts with a variety of hematological disorders were recruited. These pts came from sites in seven countries: Australia, Belgium, France, Germany, UK, Greece, and Italy. Treatment-naïve pts and those having previously received ICT (DFO or deferiprone [Ferriprox®] exclusively, or combined) participated (n=558). Pts were asked at baseline, week 4 and week 52 (end of study [EOS]) to complete the 36-item Short Form health survey (SF-36). The SF-36 is a self-administered questionnaire and measures eight HRQoL domains: physical functioning; role-physical; bodily pain; general health; vitality; social functioning; role-emotional; and mental health. Mean change in SF-36 domain scores were calculated for all pts who had completed data at baseline and week 4, as well all those with completed data at baseline and EOS. All domains are scored so that higher scores indicate a better QoL. Results: Overall, the mean age of the 558 pts (274 β-thalassemia, 168 MDS, 50 sickle cell disease and 66 other anemias) recruited to take part in this substudy was 40.8 years (SD=22.58); 51.5% of patients (n=289) were male and 48.5% (n=272) were female. Within this sample, 337 pts aged ≥16 years completed the SF-36 at baseline, 322 at week 4 and 277 at EOS. Mean domain scores for pts at baseline, week 4 and EOS are presented in Table 1. With the exception of role-emotional (mean=0.78, SD=40.56), mean change in SF-36 domain scores significantly improved (P Table 1.
