About this trial
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.
Eligibility criteria
Qualifiers
Sporadic or familial ALS, diagnosed as clinically probable, lab-supported probable, or definite ALS according to the revised El Escorial criteria
Male or female participants aged 18 to 80
Time since onset of ALS symptoms ≤28 months from Screening.
ALSFRS-R total score ≥35 at Screening
Disqualifiers
Any clinically significant and/or unstable medical (including active systemic infections requiring treatment), surgical, or psychiatric condition or laboratory abnormality other than ALS, in the judgement of the Investigator.
Active suicidality (e.g., any suicide attempts within the past 12 months or any current suicidal intent, including a plan, as assessed by the C-SSRS, score of "YES" on questions 4 or 5; and/or based on clinical evaluation by the Investigator).
Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) levels greater than 3 times the upper limit of normal (ULN).
Significant renal impairment as determined by estimated glomerular filtration rate (eGFR) of <60 mL/min.
