OBJECTIVES: To describe participant, site personnel (SP) and sponsor perspectives regarding their experiences with a decentralized clinical trial (DCT).
METHODS: COURAGE-ALS was a 48-week, double-blind, randomized, phase III, hybrid DCT of reldesemtiv versus placebo for ALS. Fifty participants completed semi-structured interviews at Week ∼22; the majority provided feedback on DCT features. Subsequently, a planned interim analysis led to termination of COURAGE-ALS for futility; 486 participants were randomized and dosed. SP completed an online survey focusing on operational aspects of the hybrid design.
RESULTS: RVs influenced the decision to pursue the trial in 13/31 participants. Remotely performing forced vital capacity (FVC) was a concern for 17/43 (40%). Survey response rate for SP was 41% (141/344). The trial was viewed as less time/labour for the site versus a traditional design by 52/136 (38%) of SP. Twenty percent (25/125) agreed their participants liked doing remote FVC assessments; 6% (7/109) of SP reported no challenges in obtaining FVC remotely. Technological problems were commonly reported by SP (71/109, 65%). Biospecimen collection and Revised Amyotrophic Lateral Sclerosis Functional Rating Scale done at in-clinic visits (ICVs) and return visits (RVs) had similar completion rates, FVCs were missed more often at RVs than ICVs (completion rates 82% vs. 96%, p < 0.001).
CONCLUSIONS AND RELEVANCE: Participants and SP viewed RVs favorably, despite common technical challenges. RV FVC assessments were more likely to be missed. COURAGE-ALS demonstrated that an interventional hybrid DCT is feasible in ALS but limitations remain that will need to be considered when designing future DCTs.
