People with amyotrophic lateral sclerosis, or ALS, often need wheelchairs to move safely. But a large study found that getting these devices depends heavily on where you live. In this trial, some participants already used manual wheelchairs, while others started new ones during the study. The data showed that those with worse scores on a standard function test were less likely to have these devices available to them. This gap in access makes it hard to compare how well different treatments work across the country. The study looked at how often people used these aids and noticed clear differences between regions in the United States, Canada, Europe, and Australia. These disparities suggest that where a person lives can change their daily reality more than the medicine they take. The trial itself was designed to test a drug called reldesemtiv against a placebo. However, researchers stopped the study early because it did not show the hoped-for benefits for the patients. This decision highlights the urgent need to address unequal access to mobility tools before they can be fairly used to measure treatment success.

This Phase 3 randomized clinical trial enrolled 482 participants with amyotrophic lateral sclerosis (ALS) across 83 sites in the United States, Canada, Europe, and Australia. Participants received reeldesemtiv or placebo for a planned total of 48 weeks, comprising 24 weeks of randomization followed by 24 weeks of active drug treatment. The trial terminated early due to futility before completing the planned follow-up period.
Analysis of device use indicated that 166 (34.4%) of 482 participants used baseline durable medical equipment (DME). Among the 276 participants completing visits through Week 24, 130 (47.1%) initiated new DME items. Manual wheelchairs were the most used items at baseline, with 89 items recorded, followed by 47 items initiated during the trial for a total of 188 new items.
The study found no impact of treatment assignment on DME use. Baseline DME use and initiation of new items were associated with lower ALS Functional Rating Scale-Revised scores and worse quality of life. The trial did not report adverse events, serious adverse events, discontinuations, or tolerability data. Regional disparities in DME access were noted as a limitation.
