ObjectiveTo determine whether rituximab is safe and potentially beneficial, warranting further investigation in an efficacy trial for acetylcholine receptor antibody-positive generalized MG (AChR-Ab+ gMG).MethodsThe B-Cell Targeted Treatment in MG (BeatMG) study was a randomized, double-blind, placebo-controlled, multicenter phase-2 trial that utilized a futility design. Individuals 21-90 years of age, with AChR-Ab+ gMG (MG Foundation of America Class II-IV) and receiving prednisone ≥15 mg/day were eligible. The primary outcome was a measure of steroid-sparing effect, defined as the proportion achieving ≥75% reduction in mean daily prednisone dose in the 4-weeks prior to week 52 and with clinical improvement or no significant worsening as compared to the 4-week period prior to randomization. The co-primary outcome was safety. Secondary outcomes included MG-specific clinical assessments. Fifty-two individuals were randomized (1:1) to either a two-cycle rituximab/placebo regimen, with follow-up through 52-weeks.ResultsOf the 52 participants included, mean (±SD) age at enrollment was 55.1 (±17.1) years; 23 (44.2%) were female, and 31 (59.6%) were MGFA Class II. The mean (±SD) baseline prednisone dose was 22.1 (±9.7) mg/day. The primary steroid-sparing outcome was achieved in 60% of those on rituximab vs. 56% on placebo. The study reached its futility endpoint (p=0.03) suggesting that the pre-defined clinically meaningful improvement of 30% due to rituximab over placebo was unlikely to be achieved in a subsequent, larger trial. No safety issues identified.ConclusionsWhile rituximab was safe and well-tolerated, these results suggest that there is a low probability of observing the defined clinically meaningful steroid-sparing effect over a 12-month period in a phase-3 trial of mild-moderately symptomatic AChR-Ab+ gMG.Classification of evidenceThis study provides Class I evidence that for mild-to-moderate AChR-Ab+ gMG, compared with placebo, rituximab is safe but unlikely to reduce steroid use by an absolute difference of at least 30% at 1 year.Trial registrationClinicalTrials.gov Identifier: NCT02110706.

ObjectiveTo determine whether ibudilast has an effect on brain volume and new lesions in progressive forms of multiple sclerosis (MS).MethodsA randomized, placebo-controlled, blinded study evaluated ibudilast at a dose of up to 100 mg over 96 weeks in primary and secondary progressive MS. In this secondary analysis of a previously reported trial, secondary and tertiary endpoints included gray matter atrophy, new or enlarging T2 lesions as measured every 24 weeks, and new T1 hypointensities at 96 weeks. Whole brain atrophy measured by structural image evaluation, using normalization, of atrophy (SIENA) was a sensitivity analysis.ResultsA total of 129 participants were assigned to ibudilast and 126 to placebo. New or enlarging T2 lesions were observed in 37.2% on ibudilast and 29.0% on placebo (p = 0.82). New T1 hypointense lesions at 96 weeks were observed in 33.3% on ibudilast and 23.5% on placebo (p = 0.11). Gray matter atrophy was reduced by 35% for those on ibudilast vs placebo (p = 0.038). Progression of whole brain atrophy by SIENA was slowed by 20% in the ibudilast group compared with placebo (p = 0.08).ConclusionIbudilast treatment was associated with a reduction in gray matter atrophy. Ibudilast treatment was not associated with a reduction in new or enlarging T2 lesions or new T1 lesions. An effect on brain volume contributes to prior data that ibudilast appears to affect markers associated with neurodegenerative processes, but not inflammatory processes.Classification of evidenceThis study provides Class II evidence that for people with MS, ibudilast does not significantly reduce new or enlarging T2 lesions or new T1 lesions.

SRX246 is a vasopressin (AVP) 1a receptor antagonist that crosses the blood-brain barrier. It reduced impulsive aggression, fear, depression and anxiety in animal models, blocked the actions of intranasal AVP on aggression/fear circuits in an experimental medicine fMRI study and demonstrated excellent safety in Phase 1 multiple-ascending dose clinical trials. The present study was a 3-arm, multicenter, randomized, placebo-controlled, double-blind, 12-week, dose escalation study of SRX246 in early symptomatic Huntingtons disease (HD) patients with irritability. Our goal was to determine whether SRX246 was safe and well tolerated in these HD patients given its potential use for the treatment of problematic neuropsychiatric symptoms. Participants were randomized to receive placebo or to escalate to 120 mg twice daily or 160 mg twice daily doses of SRX246. Assessments included standard safety tests, the Unified Huntingtons Disease Rating Scale (UHDRS), and exploratory measures of problem behaviors. The groups had comparable demographics, features of HD and baseline irritability. Eighty-two out of 106 subjects randomized completed the trial on their assigned dose of drug. One-sided exact-method confidence interval tests were used to reject the null hypothesis of inferior tolerability or safety for each dose group vs. placebo. Apathy and suicidality were not affected by SRX246. Most adverse events in the active arms were considered unlikely to be related to SRX246. The compound was safe and well tolerated in HD patients and can be moved forward as a candidate to treat irritability and aggression.

IMPORTANCE: One major advantage of developing large, federally funded networks for clinical research in neurology is the ability to have a trial-ready network that can efficiently conduct scientifically rigorous projects to improve the health of people with neurologic disorders. OBSERVATIONS: National Institute of Neurological Disorders and Stroke Network for Excellence in Neuroscience Clinical Trials (NeuroNEXT) was established in 2011 and renewed in 2018 with the goal of being an efficient network to test between 5 and 7 promising new agents in phase II clinical trials. A clinical coordinating center, data coordinating center, and 25 sites were competitively chosen. Common infrastructure was developed to accelerate timelines for clinical trials, including central institutional review board (a first for the National Institute of Neurological Disorders and Stroke), master clinical trial agreements, the use of common data elements, and experienced research sites and coordination centers. During the first 7 years, the network exceeded the goal of conducting 5 to 7 studies, with 9 funded. High interest was evident by receipt of 148 initial applications for potential studies in various neurologic disorders. Across the first 8 studies (the ninth study was funded at end of initial funding period), the central institutional review board approved the initial protocol in a mean (SD) of 59 (21) days, and additional sites were added a mean (SD) of 22 (18) days after submission. The median time from central institutional review board approval to first site activation was 47.5 days (mean, 102.1; range, 1-282) and from first site activation to first participant consent was 27 days (mean, 37.5; range, 0-96). The median time for database readiness was 3.5 months (mean, 4.0; range, 0-8) from funding receipt. In the 4 completed studies, enrollment met or exceeded expectations with 96% overall data accuracy across all sites. Nine peer-reviewed manuscripts were published, and 22 oral presentations or posters and 9 invited presentations were given at regional, national, and international meetings. CONCLUSIONS AND RELEVANCE: NeuroNEXT initiated 8 studies, successfully enrolled participants at or ahead of schedule, collected high-quality data, published primary results in high-impact journals, and provided mentorship, expert statistical, and trial management support to several new investigators. Partnerships were successfully created between government, academia, industry, foundations, and patient advocacy groups. Clinical trial consortia can efficiently and successfully address a range of important neurologic research and therapeutic questions.

BACKGROUND/AIMS: Recruitment and retention of research participants are challenging and critical components of successful clinical trials and natural history studies. Infants with spinal muscular atrophy (SMA) have been a particularly challenging population to study due to their fragile and complex medical issues, poor prognosis and, until 2016, a lack of effective therapies. Recruitment of healthy infants into clinical trials and natural history studies is also challenging and sometimes assumed to not be feasible. METHODS: In 2011, our group initiated a two-year, longitudinal natural history study of infants with SMA and healthy infant controls to provide data to assist in the analysis and interpretation of planned clinical trials in infants with SMA. The recruitment goal was to enroll 27 infants less than 6 months of age with SMA and 27 age-matched healthy infants within the two-year enrollment period. A detailed recruitment and retention plan was developed for this purpose. In addition, a survey was administered to participant families to understand the determinants of participation in the study. RESULTS: All healthy infants were recruited within the studys first year and 26 SMA infants were recruited within the two-year recruitment period. Thirty-eight participant families responded to the recruitment determinants survey. Nearly half of respondents (18/38, 48%) reported that they first heard of the study from their physician or neurologist. The most common reason to decide to enroll their infant (22/38, 58%) and to remain in the study (28/38, 74%) was their understanding of the importance of the study. Thematic recruitment tools such as a study brochure, video on social media, and presentations at advocacy meetings were reported to positively influence the decision to enroll. CONCLUSIONS: A proactive, thematic and inclusive recruitment and retention plan that effectively communicates the rationale of a clinical study and partners with patients, advocacy groups and the local communities can effectively recruit participants in vulnerable populations. Recommendations for the proactive integration of recruitment and retention plans into clinical trial protocol development are provided.

BackgroundThere are limited treatments for progressive multiple sclerosis. Ibudilast inhibits several cyclic nucleotide phosphodiesterases, macrophage migration inhibitory factor, and toll-like receptor 4 and can cross the blood-brain barrier, with potential salutary effects in progressive multiple sclerosis.MethodsWe enrolled patients with primary or secondary progressive multiple sclerosis in a phase 2 randomized trial of oral ibudilast (≤100 mg daily) or placebo for 96 weeks. The primary efficacy end point was the rate of brain atrophy, as measured by the brain parenchymal fraction (brain size relative to the volume of the outer surface contour of the brain). Major secondary end points included the change in the pyramidal tracts on diffusion tensor imaging, the magnetization transfer ratio in normal-appearing brain tissue, the thickness of the retinal nerve-fiber layer, and cortical atrophy, all measures of tissue damage in multiple sclerosis.ResultsOf 255 patients who underwent randomization, 129 were assigned to ibudilast and 126 to placebo. A total of 53% of the patients in the ibudilast group and 52% of those in the placebo group had primary progressive disease; the others had secondary progressive disease. The rate of change in the brain parenchymal fraction was -0.0010 per year with ibudilast and -0.0019 per year with placebo (difference, 0.0009; 95% confidence interval, 0.00004 to 0.0017; P=0.04), which represents approximately 2.5 ml less brain-tissue loss with ibudilast over a period of 96 weeks. Adverse events with ibudilast included gastrointestinal symptoms, headache, and depression.ConclusionsIn a phase 2 trial involving patients with progressive multiple sclerosis, ibudilast was associated with slower progression of brain atrophy than placebo but was associated with higher rates of gastrointestinal side effects, headache, and depression.

OBJECTIVE: Infantile-onset spinal muscular atrophy (SMA) is the most common genetic cause of infant mortality, typically resulting in death preceding age 2. Clinical trials in this population require an understanding of disease progression and identification of meaningful biomarkers to hasten therapeutic development and predict outcomes. METHODS: A longitudinal, multicenter, prospective natural history study enrolled 26 SMA infants and 27 control infants aged

OBJECTIVE: This study prospectively assessed putative promising biomarkers for use in assessing infants with spinal muscular atrophy (SMA). METHODS: This prospective, multi-center natural history study targeted the enrollment of SMA infants and healthy control infants less than 6 months of age. Recruitment occurred at 14 centers within the NINDS National Network for Excellence in Neuroscience Clinical Trials (NeuroNEXT) Network. Infant motor function scales and putative electrophysiological, protein and molecular biomarkers were assessed at baseline and subsequent visits. RESULTS: Enrollment began November, 2012 and ended September, 2014 with 26 SMA infants and 27 healthy infants enrolled. Baseline demographic characteristics of the SMA and control infant cohorts aligned well. Motor function as assessed by the Test for Infant Motor Performance Items (TIMPSI) and the Childrens Hospital of Philadelphia Infant Test of Neuromuscular Disorders (CHOP-INTEND) revealed significant differences between the SMA and control infants at baseline. Ulnar compound muscle action potential amplitude (CMAP) in SMA infants (1.4 ± 2.2 mV) was significantly reduced compared to controls (5.5 ± 2.0 mV). Electrical impedance myography (EIM) high-frequency reactance slope (Ohms/MHz) was significantly higher in SMA infants than controls SMA infants had lower survival motor neuron (SMN) mRNA levels in blood than controls, and several serum protein analytes were altered between cohorts. INTERPRETATION: By the time infants were recruited and presented for the baseline visit, SMA infants had reduced motor function compared to controls. Ulnar CMAP, EIM, blood SMN mRNA levels, and serum protein analytes were able to distinguish between cohorts at the enrollment visit.

ImportanceWe observed a significant correlation between cerebrospinal fluid (CSF) levels of tau proteins and α-synuclein, but not β-amyloid 1-42 (Aβ1-42), and lower concentration of CSF biomarkers, as compared with healthy controls, in a cohort of entirely untreated patients with Parkinson disease (PD) at the earliest stage of the disease studied so far.ObjectiveTo evaluate the baseline characteristics and relationship to clinical features of CSF biomarkers (Aβ1-42, total tau [T-tau], tau phosphorylated at threonine 181 [P-tau181], and α-synuclein) in drug-naive patients with early PD and demographically matched healthy controls enrolled in the Parkinson's Progression Markers Initiative (PPMI) study.Design, setting, and participantsCross-sectional study of the initial 102 research volunteers (63 patients with PD and 39 healthy controls) of the PPMI cohort.Main outcomes and measuresThe CSF biomarkers were measured by INNO-BIA AlzBio3 immunoassay (Aβ1-42, T-tau, and P-tau181; Innogenetics Inc) or by enzyme-linked immunosorbent assay (α-synuclein). Clinical features including diagnosis, demographic characteristics, motor, neuropsychiatric, and cognitive assessments, and DaTscan were systematically assessed according to the PPMI study protocol.ResultsSlightly, but significantly, lower levels of Aβ1-42, T-tau, P-tau181, α-synuclein, and T-tau/Aβ1-42 were seen in subjects with PD compared with healthy controls but with a marked overlap between groups. Using multivariate regression analysis, we found that lower Aβ1-42 and P-tau181 levels were associated with PD diagnosis and that decreased CSF T-tau and α-synuclein were associated with increased motor severity. Notably, when we classified patients with PD by their motor phenotypes, lower CSF Aβ1-42 and P-tau181 concentrations were associated with the postural instability-gait disturbance-dominant phenotype but not with the tremor-dominant or intermediate phenotype. Finally, we found a significant correlation of the levels of α-synuclein with the levels of T-tau and P-tau181.Conclusions and relevanceIn this first report of CSF biomarkers in PPMI study subjects,we found that measures of CSF Aβ1-42, T-tau, P-tau181, and α-synuclein have prognostic and diagnostic potential in early-stage PD. Further investigations using the entire PPMI cohort will test the predictive performance of CSF biomarkers for PD progression

Objective: Examine preventive medication adherence among youth with migraine.Methods: Adherence (self-report, pill count, and blood serum drug levels) was assessed as an ancillary study that utilized data from 328 CHAMP Study participants (ages 8-17). CHAMP was a multisite trial of preventive medications. Participants completed a prospective headache diary during a six-month active treatment period during which youth took amitriptyline, topiramate, or placebo pill twice daily. Self-reported medication adherence was collected via daily diary. At monthly study visits, pill count measures were captured. At trial month 3 (trial midpoint) and 6 (end of active trial), blood serum drug levels were obtained. Self-report and pill count adherence percentages were calculated for the active trial period, at each monthly study visit, and in the days prior to participants' mid-trial blood draw. Percentages of nonzero drug levels were calculated to assess blood serum drug level data. Adherence measures were compared and assessed in context of several sociodemographic factors. Multiple regression analyses investigated medication adherence as a predictor of headache outcomes.Results: Self-report and pill count adherence rates were high (over 90%) and sustained over the course of the trial period. Serum drug level adherence rates were somewhat lower and decreased significantly (from 84% to 76%) across the trial period [t (198) = 3.23, p = .001]. Adherence measures did not predict headache days at trial end; trial midpoint serum drug levels predicted headache-related disability.Conclusions: Youth with migraine can demonstrate and sustain relatively high levels of medication adherence over the course of a clinical trial.

Objectives. Older adults may experience weight changes upon retirement for a number of reasons, such as being less physically active; having less structured meal times; and consuming food in response to losing personal identity, the potential for social interactions, or the sense of accomplishment derived from working. The purpose of this study was to determine whether retirement was associated with either weight gain or weight loss. Methods. We used the 1994-2002 Health and Retirement Study to determine whether retirement between biennial interviews was associated with weight change, separately for men (n = 1,966) and women (n = 1,759). We defined weight change as a 5% increase or decrease in body mass index between interviews. Results. We did not find a significant association between retirement and weight change among men. Women who retired were more likely to gain weight than women who continued to work at least 20 hr per week (odds ratio [OR] = 1.24, 95% confidence interval [CI] = 1.04-1.48). We found a significant relationship between retirement and weight gain only for women who were normal weight upon retiring (OR = 1.30, 95% CI = 1.01-1.69) and who retired from blue-collar jobs (OR = 1.58, 95% CI = 1.13-2.21). Discussion. Public health interventions may be indicated for women, particularly those working in blue-collar occupations, in order to prevent weight gain upon retirement. Key Words: Weight Retirement--Longitudinal research--Aging.

Objectives. The purpose of this study was to clarify the direction of the relationship between changes in depressive symptoms and changes in weight in older adults. Methods. The sample included a prospective cohort of individuals aged 53-63 (n = 9,130) enrolled in the Health and Retirement Study. We used separate cross-lagged models for men and women in order to study the impact of weight change on subsequent increases in depressive symptoms 2 years later and vice versa. Results. Weight gain did not lead to increased depressive symptoms, ,and weight loss preceded increased depressive symptoms only in unadjusted models among men (odds ratio [OR] = 1.26, 95% confidence interval [CI] = 1.04-1.53). Increased depressive symptoms were not predictive of subsequent weight loss, but they were predictive of subsequent weight gain in unadjusted models only (men: OR = 1.24, 95% CI = 1.00-1.54; women: OR = 1.12, 95% CI = 1.00-1.26). In adjusted models, baseline depressive symptoms predicted both weight loss and weight gain among both men and women. Increase in functional limitations and medical conditions were significant predictors of both weight loss and weight gain. Baseline functional limitations also predicted increased depressive symptoms. Discussion. Based on our findings, it is apparent that researchers need to examine the pathways between changes in weight and increases in depressive symptoms in the context of functional limitations and medical comorbidity.

Background: We developed a remote cardiovascular risk service (CVRS) managed by clinical pharmacists to support primary care teams. The purpose of this study was to examine whether the CVRS could improve guideline adherence in primary care clinics with diverse geographic and patient characteristics. Methods: This study was a cluster‐randomized trial initiated in 20 primary care clinics across the United States. Clinics were stratified as a high or low minority and then randomized to receive the intervention or maintain usual care for 12 months. The primary outcome was adherence to relevant The Guideline Advantage (TGA) criteria met. TGA is a compilation of criteria from practice guidelines intended to improve the quality of primary care. Post‐hoc outcomes included changes in individual TGA measures. Results: A total of 401 study subjects were included in the analysis. Mean TGA scores remained the same in the intervention group (n = 193, 0.72) and slightly decreased in the usual care group (n = 208, 0.67‐0.66) over the 12‐month study period. There was no significant difference between the mean TGA scores in the intervention and usual care groups for the overall population at 12 months (0.72 vs 0.66, respectively, P =.10). For under‐represented minority subjects, there was no significant difference between TGA scores at 12 months (n = 186; 0.70 vs 0.67, respectively, P =.50). In a post‐hoc analysis of subjects uncontrolled at baseline, there was a significant improvement in systolic BP at 12 months in the intervention group vs usual care (model‐based difference of −8.03 mmHg, P =.03). Conclusions: Improvements in individual TGA measures were limited, in part, due to higher‐than‐expected baseline TGA scores. Future studies of this model should focus on patients with uncontrolled conditions at high risk for cardiovascular events.

Background: The SPRINT-MS trial demonstrated benefit of ibudilast on brain atrophy over 96 weeks in progressive multiple sclerosis (MS). Optical coherence tomography (OCT) was performed in all trial participants. Objective: Report the OCT results of the SPRINT-MS trial. Methods: OCT was obtained at baseline and every 6 months using spectral domain OCT and analyzed by an OCT reading center. Change in each OCT outcome measure by treatment group was estimated using linear mixed models. Results: Change in pRNFL thickness was +0.0424 uM/year (95% confidence interval (CI): −0.3091 to 0.3939) for ibudilast versus −0.2630 uM (95% CI: −0.5973 to 0.0714) for placebo (n = 244, p = 0.22). Macular volume change was −0.00503 mm3/year (−0.02693 to 0.01688) with ibudilast versus −0.03659 mm3/year (−0.05824 to −0.01494) for placebo in the Spectralis cohort (n = 61, p = 0.044). For the Cirrus cohort, macular volume change was −0.00040 mm3/year (−0.02167, 0.020866) with ibudilast compared to −0.02083 mm3/year (−0.04134 to −0.00033) for placebo (n = 183, p = 0.1734). Ganglion cell-inner plexiform layer thickness change, available from Cirrus, was −0.4893 uM/year (−0.9132, −0.0654) with ibudilast versus −0.9587 uM/year (−1.3677, −0.5498) with placebo (n = 183, p = 0.12). Conclusion: Retinal thinning in MS may be attenuated by ibudilast. Sample size estimates suggest OCT can be a viable outcome measure in progressive MS trials if a therapy has a large treatment effect.

Objective: Determine whether a treatment effect of ibudilast on brain atrophy rate differs between participants with primary (PPMS) and secondary (SPMS) progressive multiple sclerosis. Background: Progressive forms of MS are both associated with continuous disability progression. Whether PPMS and SPMS differ in treatment response remains unknown. Design/Methods: SPRINT‐MS was a randomized, placebo‐controlled 96‐week phase 2 trial in both PPMS (n = 134) and SPMS (n = 121) patients. The effect of PPMS and SPMS phenotype on the rate of change of brain atrophy measured by brain parenchymal fraction (BPF) was examined by fitting a three‐way interaction linear‐mixed model. Adjustment for differences in baseline demographics, disease measures, and brain size was explored. Results: Analysis showed that there was a three‐way interaction between the time, treatment effect, and disease phenotype (P < 0.06). After further inspection, the overall treatment effect was primarily driven by patients with PPMS (P < 0.01), and not by patients with SPMS (P = 0.97). This difference may have been due to faster brain atrophy progression seen in the PPMS placebo group compared to SPMS placebo (P < 0.02). Although backward selection (P < 0.05) retained age, T2 lesion volume, RNFL, and longitudinal diffusivity as significant baseline covariates in the linear‐mixed model, the adjusted overall treatment effect was still driven by PPMS (P < 0.01). Interpretation: The previously reported overall treatment effect of ibudilast on worsening of brain atrophy in progressive MS appears to be driven by patients with PPMS that may be, in part, because of the faster atrophy progression rates seen in the placebo‐treated group.
