Treatment With Mycophenolate and Cyclophosphamide Leads to Clinically Meaningful Improvements in Patient-Reported Outcomes in Scleroderma Lung Disease: Results of Scleroderma Lung Study II.

ABSTRACT: OBJECTIVE:Our objective was to determine if treatment with cyclophosphamide (CYC) and mycophenolate mofetil (MMF) improves patient-reported outcomes (PROs) among patients with systemic sclerosis-related interstitial lung disease (SSc-ILD). METHODS:This study examined PROs in patients with SSc-ILD (N = 142) who participated in the Scleroderma Lung Study II, a randomized controlled trial comparing MMF for 2 years with oral CYC for 1 year followed by 1 year of a placebo. Joint models were created to evaluate the course of PROs over 2 years. The difference in PRO scores from baseline to 24 months was measured, and the percentage of patients meeting the minimum clinically important difference (MCID) was calculated. Correlations between PROs and SSc-ILD disease severity measures were also examined. RESULTS:Treatment with CYC and MMF led to improvements in several PROs with no between-treatment differences. Scores for the Transitional Dyspnea Index (TDI) and St. George's Respiratory Questionnaire (SGRQ) improved significantly over 2 years, and 29%/24% and 28%/25% of participants in the CYC/MMF groups met or exceeded the MCID estimates for TDI and SGRQ, respectively. At baseline, the forced vital capacity (FVC) percentage predicted (FVC%-predicted) did not correlate with the Baseline Dyspnea Index or SGRQ. However, improvements in the FVC%-predicted were weakly associated with improvements in dyspnea (assessed by the TDI) and SGRQ scores. CONCLUSION:Treatment with CYC and MMF improved overall health-related quality of life in patients with SSc-ILD. The relationship between PRO measures and the FVC was relatively weak, suggesting that PROs provide complementary information about treatment efficacy not captured by changes in the FVC alone in this patient population.

Project description:12 months of oral cyclophosphamide has been shown to alter the progression of scleroderma-related interstitial lung disease when compared with placebo. However, toxicity was a concern and without continued treatment the efficacy disappeared by 24 months. We hypothesised that a 2 year course of mycophenolate mofetil would be safer, better tolerated, and produce longer lasting improvements than cyclophosphamide.This randomised, double-blind, parallel group trial enrolled patients from 14 US medical centres with scleroderma-related interstitial lung disease meeting defined dyspnoea, pulmonary function, and high-resolution CT (HRCT) criteria. The data coordinating centre at the University of California, Los Angeles (UCLA, CA, USA), randomly assigned patients using a double-blind, double-dummy, centre-blocked design to receive either mycophenolate mofetil (target dose 1500 mg twice daily) for 24 months or oral cyclophosphamide (target dose 2·0 mg/kg per day) for 12 months followed by placebo for 12 months. Drugs were given in matching 250 mg gel capsules. The primary endpoint, change in forced vital capacity as a percentage of the predicted normal value (FVC %) over the course of 24 months, was assessed in a modified intention-to-treat analysis using an inferential joint model combining a mixed-effects model for longitudinal outcomes and a survival model to handle non-ignorable missing data. The study was registered with ClinicalTrials.gov, number NCT00883129.Between Sept 28, 2009, and Jan 14, 2013, 142 patients were randomly assigned to either mycophenolate mofetil (n=69) or cyclophosphamide (n=73). 126 patients (mycophenolate mofetil [n=63] and cyclophosphamide [n=63]) with acceptable baseline HRCT studies and at least one outcome measure were included in the primary analysis. The adjusted % predicted FVC improved from baseline to 24 months by 2·19 in the mycophenolate mofetil group (95% CI 0·53-3·84) and 2·88 in the cyclophosphamide group (1·19-4·58). The course of the % FVC did not differ significantly between the two treatment groups based on the prespecified primary analysis using a joint model (p=0·24), indicating that the trial was negative for the primary endpoint. However, in a post-hoc analysis of the primary endpoint, the within-treatment change from baseline to 24 months derived from the joint model showed that the % FVC improved significantly in both the mycophenolate mofetil and cyclophosphamide groups. 16 (11%) patients died (five [7%] mycophenolate mofetil and 11 [15%] cyclophosphamide), with most due to progressive interstitial lung disease. Leucopenia (30 patients vs four patients) and thrombocytopenia (four vs zero) occurred more often in patients given cyclophosphamide than mycophenolate mofetil. Fewer patients on mycophenolate mofetil than on cyclophosphamide prematurely withdrew from study drug (20 vs 32) or met prespecified criteria for treatment failure (zero vs two). The time to stopping treatment was shorter in the cyclophosphamide group (p=0·019).Treatment of scleroderma-related interstitial lung disease with mycophenolate mofetil for 2 years or cyclophosphamide for 1 year both resulted in significant improvements in prespecified measures of lung function over the 2 year course of the study. Although mycophenolate mofetil was better tolerated and associated with less toxicity, the hypothesis that it would have greater efficacy at 24 months than cyclophosphamide was not confirmed. These findings support the potential clinical effectiveness of both cyclophosphamide and mycophenolate mofetil for progressive scleroderma-related interstitial lung disease, and the present preference for mycophenolate mofetil because of its better tolerability and toxicity profile.National Heart, Lung and Blood Institute, National Institutes of Health; with drug supply provided by Hoffmann-La Roche and Genentech.

Project description:BackgroundWalking impairment is a hallmark of multiple sclerosis (MS). It affects > 90% of individuals over time, reducing independence and negatively impacting health-related quality of life, productivity, and daily activities. Walking impairment is consistently reported as one of the most distressing impairments by individuals with MS. Prolonged-release (PR)-fampridine previously has been shown to improve objectively measured walking speed in walking-impaired adults with MS. The impact of PR-fampridine from the perspective of the individual with MS warrants full and detailed examination.ObjectiveThe objective of this study was to evaluate whether PR-fampridine has a clinically meaningful effect on self-reported walking ability in walking-impaired participants with MS.MethodsENHANCE was a phase III, randomized, double-blind, placebo-controlled study of PR-fampridine 10 mg twice daily in walking-impaired individuals age 18-70 years with either relapsing or progressive forms of MS and an Expanded Disability Status Scale (EDSS) score of 4.0-7.0 at screening. Participants were stratified by EDSS score (≤ 6.0 or 6.5-7.0) at randomization to ensure a balanced level of disability in the treatment groups. The primary endpoint was the proportion of participants with a mean improvement in the 12-item Multiple Sclerosis Walking Scale (MSWS-12) score exceeding the predefined threshold for clinically meaningful improvement (≥ 8 points) over 24 weeks. Secondary endpoints included the proportion with ≥ 15% improvement in Timed Up and Go (TUG) speed, and mean changes in Multiple Sclerosis Impact Scale physical impact subscale (MSIS-29 PHYS), Berg Balance Scale (BBS), and ABILHAND scores over 24 weeks.ResultsIn total, 636 participants with MS were randomized (PR-fampridine, n = 317; placebo, n = 319; modified intention-to-treat sample: PR-fampridine, n = 315; placebo, n = 318). At baseline in the PR-fampridine and placebo groups, 46% and 51% had a progressive form of MS, median [range] EDSS scores were 6.0 [4.0-7.0] and 5.5 [4.0-7.0], mean [range] MSWS-12 scores were 63.6 [0-100] and 65.4 [0-100], and mean [range] TUG speed was 0.38 [0.0-1.0] and 0.38 [0.0-1.2] feet/s, respectively. A significantly higher percentage of PR-fampridine-treated participants (136/315 [43.2%]) had clinically meaningful improvement in MSWS-12 score over 24 weeks versus placebo (107/318 [33.6%]; odds ratio 1.61 [95% confidence interval 1.15-2.26]; p = 0.006). For PR-fampridine versus placebo, significantly more participants had a ≥ 15% improvement in TUG speed, and there was significantly greater mean improvement in MSIS-29 PHYS score (p < 0.05); numerical improvements that were not statistically significant were observed in BBS/ABILHAND. Adverse events that were more common in the PR-fampridine group than placebo group (difference ≥ 3%) by Medical Dictionary for Regulatory Activities (MedDRA®) Preferred Term were urinary tract infection and insomnia. There were no seizures reported.ConclusionsPR-fampridine treatment resulted in sustained, clinically meaningful improvements over 24 weeks in self-reported walking and functional ability in walking-disabled participants with MS.

Project description:Allogeneic hematopoietic cell transplantation (HCT) cures many patients, but often with the risk of late effects and impaired quality of life. The value of quantifying patient-reported outcomes (PROs) is increasingly being recognized, but the routine collection of PROs is uncommon. This study evaluated the feasibility of prospective PRO collection by an outcome registry at multiple time points from unselected HCT patients undergoing transplantation at centers contributing clinical data to the Center for International Blood and Marrow Transplant Research (CIBMTR), and then it correlated the PRO data with clinical and demographic data.The Functional Assessment of Cancer Therapy-Bone Marrow Transplant (FACT-BMT), 36-Item Short Form Health Survey (SF-36), and Pediatric Quality of Life Inventory measures were administered before HCT, on day 100, and at 6 and 12 months. Patients were recruited by the transplant center, but posttransplant PRO collection was managed centrally by the CIBMTR.There were 580 eligible patients, and 390 (67%) enrolled. Feasibility was shown by high time-specific retention rates (176 of 238 at 1 year or 74%) and participant satisfaction. Factors associated with higher response rates were an age?>?50 years (odds ratio [OR], 1.58; 95% confidence interval [CI], 1.03-2.41; P?=?.0355), white race (OR, 4.61; 95% CI, 2.66-7.99; P?<?.0001), and being married (OR, 2.28; 95% CI, 1.42-3.65; P?=?.0006) for adults and a higher family income for children (OR, 4.99; 95% CI, 2.12-11.75; P?=?.0002). Importantly, pre-HCT PRO scores independently predicted survival after adjustments for patient-, disease-, and transplant-related factors. The adjusted probabilities of 1-year survival were 56%, 67%, 75%, and 76% by increasing quartiles of the pre-HCT FACT-BMT score and 58%, 72%, 62%, and 82% by increasing quartiles of the pre-HCT SF-36 physical component score.A hybrid model of local consent for centralized PRO collection is feasible, and pretransplant PROs provide critical prognostic information for HCT outcomes.

Project description:ObjectiveTo compare mycophenolate mofetil (MMF) with placebo for the treatment of systemic sclerosis (SSc)-related interstitial lung disease (ILD).MethodsWe included participants enrolled in the placebo arm of Scleroderma Lung Study (SLS) I and the MMF arm of SLS II. SLS I randomized participants to receive either oral cyclophosphamide (CYC) or placebo for 1 year, while SLS II randomized participants to receive either MMF for 2 years or oral CYC for 1 year followed by 1 year of placebo. Eligibility criteria for SLS I and SLS II were nearly identical. The primary outcome was % predicted forced vital capacity (FVC), and key secondary outcomes included % predicted diffusing capacity for carbon monoxide (DLco), the modified Rodnan skin thickness score (MRSS), and dyspnea. Joint models were created to evaluate the treatment effect on the course of these outcomes over 2 years.ResultsAt baseline, the MMF-treated group in SLS II (n = 69) and the placebo-treated group in SLS I (n = 79) had similar percentages of men and women and similar disease duration, SSc subtype, extent of skin disease, and % predicted FVC. MMF-treated patients in SLS II were slightly older (mean ± SD age 52.6 ± 9.7 years versus 48.1 ± 12.4 years; P = 0.0152) and had higher % predicted DLco (mean ± SD 54.0 ± 11.1 versus 46.2 ± 13.3; P = 0.0002) than placebo-treated patients in SLS I. After adjustment for baseline disease severity, treatment with MMF in comparison with placebo was associated with improved % predicted FVC (P < 0.0001), % predicted DLco (P < 0.0001), MRSS (P < 0.0001), and dyspnea (P = 0.0112) over 2 years.ConclusionAlthough there are inherent limitations in comparing participants from different trials, treatment with MMF was associated with improvements in physiologic outcomes and dyspnea compared with placebo, even after accounting for baseline disease severity. These results further substantiate the use of MMF for the treatment of SSc-related ILD.
