Brief Summary:

This is a Phase 2a, multi-center, open label, multiple dose study of AT-1501, a humanized monoclonal antibody antagonist to CD40L. Approximately 54 adults with ALS will be enrolled into the study in the United States and Canada at approximately 13 ALS treatment sites.

Participants will be enrolled into one of four ascending doses.

Condition or disease Intervention/treatment Phase
Amyotrophic Lateral Sclerosis Drug: AT-1501 Phase 2

Detailed Description:

This is a Phase 2a, multi-center, open label, multiple dose study of AT-1501, a humanized monoclonal antibody antagonist to CD40L. Approximately 54 adults with ALS will be enrolled into the study in the United States and Canada at approximately 13 ALS treatment sites.

Four ascending doses of AT-1501 will be administered as an IV infusion to sequentially enrolling cohorts. Each participant will receive 6 bi-weekly (every other week) infusions of AT-1501 over an 11-week period.

The study is estimated to take 19 weeks for participants.
