Phase 2 trial tests new asthma drug amlitelimab in adults with moderate-to-severe asthma

Plain Language Summary
What this means for you:
An early trial tested a new asthma drug, but results aren't available yet. More research is needed.

A recent clinical trial tested a new potential asthma treatment called amlitelimab. The study involved 437 adults from around the world who have moderate-to-severe asthma. Researchers wanted to see if adding amlitelimab to their current asthma medications could help reduce severe asthma attacks over 48 weeks. They tested different doses of the drug against a placebo, which is a treatment with no active medicine.

This was a Phase 2 trial, which means it's an early-stage study designed mainly to test different doses and gather initial information. The trial has been completed, but the specific results about whether amlitelimab actually reduced asthma attacks or caused any side effects have not been made public yet.

Because this is an early study and we don't have the results, it's important to understand that amlitelimab is still experimental. The drug's sponsor, Sanofi, conducted the research. Readers should know that many drugs tested in Phase 2 trials don't end up being approved or available for patients.

For now, the main takeaway is that research continues on new asthma treatments, but we need to wait for the actual study results to understand if amlitelimab might be helpful and safe for people with asthma.

Status: COMPLETED | Phase: PHASE2 Condition(s): Asthma Intervention(s): Amlitelimab (DRUG), Placebo (DRUG) This was a parallel, Phase 2, global, multicenter, randomized, double-blind, placebo-controlled, dose-ranging, four-arms study for treatment. The purpose of this study was to assess the efficacy, safety, and tolerability of add-on therapy with amlitelimab in adult participants with moderate-to-severe asthma. Study details include: * The study duration (per participant) was up to approximately 76 weeks for participants not going into LTS study and will be up to approximately 64 weeks for participants going into LTS study. * The randomized treatment duration was up to approximately 60 weeks. * The scheduled number of visits was 13. Primary Outcome(s): Annualized Rate of Severe Asthma Exacerbation Events Over 48 Weeks Enrollment: 437 (ACTUAL) Lead Sponsor: Sanofi Start: 2022-06-30 | Primary Completion: 2024-10-11 Results posted: 2026-03-30
