COMBAT-ALS Trial Summary

This trial is testing a potential ALS treatment. It will last 18 months and compare the drug to a placebo.

Who is the study for?
This trial is for adults aged 18-80 with ALS diagnosed within the last 18 months. Participants must have a certain level of lung function and be able to swallow pills, without severe liver issues or psychiatric disorders that could interfere with assessments. They shouldn't be on high-dose Vitamin B12 injections or involved in other studies recently.Check my eligibility
What is being tested?
The study tests MN-166 against a placebo over 12 months to see if it's effective and safe for ALS patients, followed by everyone getting MN-166 for another six months. It's randomized (participants are put into groups by chance) and double-blind (neither participants nor researchers know who gets what treatment).See study design
What are the potential side effects?
While specific side effects aren't listed here, common ones may include gastrointestinal symptoms like nausea or diarrhea, potential allergic reactions, or changes in liver enzymes which will be monitored throughout the trial.
