Summary

This Phase 3 trial tests an oral drug called deucrictibant in adults with acquired angioedema due to C1 inhibitor deficiency, a rare condition causing sudden, painful swelling attacks. The study has three parts: one to see if a daily extended-release tablet can prevent attacks, another to test an immediate-release capsule for on-demand treatment, and an open-label part for long-term safety. About 32 participants will be enrolled to compare the drug against placebo.

What this could lead to

If successful, this could provide a new oral option to prevent and treat swelling attacks in people with acquired angioedema, reducing the need for emergency care.

What could go wrong

This is a small Phase 3 trial with only 32 participants, so results may not apply to everyone. The drug may not work better than placebo, and side effects are still being studied.
