Safety of Engensis in Participants With Amyotrophic Lateral Sclerosis
NCT04632225 · View on ClinicalTrials.gov ↗
Study 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.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04632225
The ClinicalTrials.gov registry entry for NCT04632225 describes a study currently listed as completed. It is categorized as Phase 2, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 18 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Helixmith Co., which has 3 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Amyotrophic Lateral Sclerosis appearing as the primary indexed condition, and to 2 interventions — of which Placebo is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04632225 reports 5 study locations spanning 5 distinct geographic areas — top geographies include Arizona, Illinois, Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
