Summary

Researchers are testing whether low-dose colchicine, an anti-inflammatory drug, can slow the decline in function caused by ALS. The trial enrolls 87 adults with ALS who already take riluzole, the standard treatment. Participants receive colchicine or a placebo for 30 weeks, then everyone receives colchicine for another 36 weeks. The main measure is how much the ALS Functional Rating Scale-Revised score changes over time.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
low-dose colchicine, an anti-inflammatory drug, added to standard riluzole therapy
What this could lead to
If it works, low-dose colchicine could become an add-on pill that helps slow ALS progression alongside riluzole.
What could go wrong
This is a mid-stage trial with 87 participants, so any benefit may be small or may not hold up in larger studies. Colchicine can cause stomach upset and, rarely, muscle or blood problems.

Inclusion Criteria: * Patient age strictly between 18 and 80 years at the time of screening. * Definitively established diagnosis of ALS (sporadic or familial) matching standardized clinical consensus parameters. * Stable background regimen of European gold-standard Riluzole therapy maintained at a fixed dose of 100 mg/day for a minimum of 1 month prior to baseline randomization. * BMI\>17.5 Kg/m2 * Sufficient respiratory capability, verified by an upright Forced Vital Capacity (FVC) \>= 70% of predicted normal values at screening (highest value of three sequential tests). * Patient must display full cognitive and communicative capacity to provide written, personally signed Independent Ethics Committee-approved Informed Consent prior to initiation of any protocolized procedures. * Use of highly effective contraception both for males and females Exclusion Criteria: * Concurrent participation or treatment within any other interventional or drug-based clinical trial. * Clinically significant hepatic impairment (defined as baseline serum transaminases AST or ALT exceeding 3x Upper Limit of Normal \[ULN\], or total bilirubin exceeding 2x ULN). * Severe renal insufficiency, documented bone marrow suppression, or significant hematological abnormalities. * Known hypersensitivity or systemic intolerance to colchicine or any of the manufacturing excipients (lactose, sucrose, magnesium stearate, arabic gum). * Pregnancy, active lactation, or unwillingness of fertile male/female subjects to strictly comply with highly effective double-barrier contraception regimens throughout the study and for 100 days post-final dose.
