What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

The goal of this clinical trial is to evaluate whether low-dose colchicine can slow disease progression in patients with amyotrophic lateral sclerosis (ALS), a progressive and fatal neurodegenerative disorder affecting motor neurons. The study is designed to answer whether patients receiving colchicine show a slower decline in functional status, as measured by the ALS Functional Rating Scale-Revised (ALSFRS-R), over a 30-week double-blind treatment period compared to patients receiving placebo. Additional questions include whether colchicine has an effect on respiratory function, disability progression, quality of life, and overall survival. Researchers will compare participants receiving colchicine at a dose of 0.005 mg/kg/day with those receiving placebo, both in addition to standard-of-care therapy with riluzole, to assess potential differences in disease progression. Participants will be randomly assigned in a 2:1 ratio to colchicine or placebo. They will take the assigned study medication for 30 weeks during a double-blind phase and then continue into a 36-week open-label extension phase, during which all participants will receive colchicine while remaining blinded to their initial treatment assignment. Throughout the study, participants will undergo regular clinical evaluations, including assessments of motor and respiratory function, functional disability, and quality of life, for a total follow-up period of up to 66 weeks. Blood samples will also be collected to investigate biological markers of neurodegeneration and inflammation.

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.
