The participants' perspective on facioscapulohumeral muscular dystrophy trials in The Netherlands - A qualitative study.

BACKGROUND

Facioscapulohumeral muscular dystrophy (FSHD) is a hereditary muscle disease without an available cure. The first trials with potentially disease-modifying therapies have started, including a phase ll open-label study and a phase lll double-blind randomized placebo-controlled trial assessing the safety and efficacy of losmapimod. Having a more in-depth understanding of the patient's experience of these trials will further enhance the design and recruitment of future trials.

OBJECTIVE

To explore the motivation, expectations, concerns, and experiences of FSHD patients in the first clinical trials in the Netherlands resulting in recommendations for future trials.

METHODS

Semi-structured interviews with participants of phase II and III losmapimod trials were conducted. The interview guide was based on previous conducted literature reviews and consultation of a patient representative. Participants were selected through convenience sampling. Four main themes were discussed: motivation for participation, expectations regarding study drug and trial visits, trial participation experience, and recommendations for future trials. The interviews were transcribed, anonymized, and analyzed using Atlas.ti version 23.1.1 using a deductive approach.

RESULTS

Thirteen participants were interviewed; six phase II participants and seven phase III participants. The primary motivations to participate concerned altruistic motives, contribute to science or improve their own health status. The participants had realistic expectations of the effect of the study drug before trial participation. Overall, participants were positive about their trial participation. Specifically, the personal and transparent communication within a trusting and dedicated trial team was appreciated. The phase III participants reported a higher than expected psychological burden on participating in a placebo-controlled trial. Recommendations consisted of more frequent updates on the overall progress and results of the trials.

CONCLUSIONS

This study presents the participants' perspective on FSHD trials, providing important key findings for future clinical trial design, study site practices and patient education.
