Safety of Engensis in Participants With Amyotrophic Lateral Sclerosis

Summary

The purpose of this study was to evaluate the safety of intramuscular administration of Engensis in Participants with Amyotrophic Lateral Sclerosis as compared to Placebo. Safety will be assessed by incidences of treatment-emergent adverse events, treatment-emergent serious adverse events, injection site reactions and other adverse events of special interest, and the clinically significant laboratory values after injections of Engensis compared to Placebo. Exploratory endpoints include assessment of muscle function using the Revised Amyotrophic Lateral Sclerosis Functional Rating Scale subscores for Fine and Gross Motor Function; muscle strength by quantitative testing using handheld dynamometry and the Accurate Test of Limb Isometric Strength where available; quality of life using the Amyotrophic Lateral Sclerosis Assessment Questionnaire-40; patient global impression of change, clinical global impression of change, and clinical global impression of severity; and evaluation of lung function using Slow Vital Capacity. Muscle biopsies will be performed during the study for future biomarker analyses.
