The purpose of this study is to evaluate how well LY4256984 is tolerated and what side effects may occur in participants with sporadic amyotrophic lateral sclerosis (ALS). The study drug will be administered intrathecally (IT) into the spine. Blood tests will be performed to check how much LY4256984 gets into the bloodstream and how long it takes the body to eliminate it.
Phase 1 trials primarily test safety and dosing in a small number of participants (typically 20–100). Results do not yet speak to efficacy. FDA approval is typically many years away from this stage.
Currently recruiting: the trial is enrolling patients. A data readout is not expected until after enrollment closes and the follow-up period is complete.
Eli Lilly and Company (LLY) is the sponsoring company for this trial. BiotechSign currently grades this company C (54/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
