The primary endpoint of the study was the change of the VAS-3 (3-symptom composite visual analogue scale) score from pre-treatment to 4 hours post-treatment. The VAS-3 was calculated as the mean of the VAS scores of the 3 major HAE symptoms: skin swelling, skin pain, and abdominal pain. The VAS scores of the 3 major HAE symptoms (skin swelling, skin pain, and abdominal pain) could range between 0 (No swelling/No pain) and 100 (Extreme swelling/Excruciating pain)

Frequently asked questions about Deucrictibant

What is Deucrictibant used for?

Deucrictibant is an investigational oral small molecule being developed for hereditary angioedema (HAE) and acquired angioedema due to C1-inhibitor deficiency (AAE-C1-INH). It is studied for both acute treatment of angioedema attacks and prophylaxis to prevent attacks. The drug is in Phase 3 clinical development and has not been approved by the FDA.

How does Deucrictibant work?

Deucrictibant is a small molecule that targets the bradykinin B2 receptor. By blocking this receptor, it is designed to reduce the swelling and pain associated with angioedema attacks. The drug is being evaluated in clinical trials for its efficacy and safety in treating and preventing angioedema episodes.

Who is developing Deucrictibant?

Deucrictibant is being developed by Pharvaris N.V., a biopharmaceutical company traded on the NASDAQ under the ticker PHVS. Pharvaris is focused on developing oral therapies for rare diseases, with Deucrictibant being a lead candidate for hereditary angioedema and related conditions.

What phase is Deucrictibant in?

Deucrictibant is currently in Phase 3 clinical development. It has completed Phase 2 trials for acute treatment and prophylaxis of hereditary angioedema, and a Phase 3 trial is recruiting for acquired angioedema due to C1-inhibitor deficiency. The drug is investigational and not yet approved by regulatory authorities.

What clinical trials is Deucrictibant in?

Deucrictibant has been studied in several clinical trials. Completed Phase 2 trials include NCT04618211 for acute treatment of HAE attacks and NCT05047185 for prophylaxis in HAE. An extension study NCT05396105 is enrolling by invitation. A Phase 3 trial NCT07266805 is recruiting for AAE-C1-INH, testing both prophylaxis and on-demand treatment.

Is Deucrictibant the same as PHA-022121?

Yes, Deucrictibant is also known as PHA-022121. Clinical trials for the drug have used the name PHA-022121 in their titles, such as the dose-ranging studies for acute treatment and prophylaxis of hereditary angioedema. The drug is now referred to as Deucrictibant in later-stage development.
