Official title
Phase 2/3, Randomized, Double-Blind, Placebo-Controlled, Multi-Center, 24-Week Study With Additional 24-Week Blinded Active Extension to Evaluate the Safety and Efficacy of COYA 302 for the Treatment of Amyotrophic Lateral Sclerosis (ALS)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The ALSTARS trial will be conducted across 20-25 sites in the US and Canada, and will evaluate the safety and efficacy of an investigational treatment called COYA 302 for adults with Amyotrophic Lateral Sclerosis (ALS). COYA 302 is an investigational and proprietary biologic combination therapy with a dual immunomodulatory mechanism of action intended to enhance the anti-inflammatory function of regulatory T cells (Tregs) and suppress the inflammation produced by activated monocytes and macrophages. It is comprised of low dose interleukin-2 (LD IL-2) and DRL\_AB (a biosimilar candidate for abatacept). Participants will be randomly assigned to receive one of 2 regimens of COYA 302 or placebo (an inactive substance) in a 1:1:1 ratio for 24 weeks in the double-blind (DB) period. Those who complete this part of the study will be eligible to receive one of the two regimens of COYA 302 for an additional 24 weeks in a blinded active extension phase (EXT). The study will assess changes in disease progression using established ALS clinical outcome measures, including the ALS Functional Rating Scale-Revised (ALSFRS-R), neurofilament (NfL), maximal inspiratory pressure (MIP), slow vital capacity (SVC), and neurological assessments. Additional objectives include evaluation of biomarkers and safety through routine clinical assessments and adverse event monitoring.
