Hold Lifted on Pharvaris Angioedema Drug
FDA has lifted a clinical hold on a Pharvaris deucrictibant clinical trial for the on-demand treatment of hereditary angioedema (HAE) attacks. There still remains a hold on a separate trial for the drug’s prophylactic treatment of HAE, which the company says it will address when it submits data from its 26-week nonclinical study by the end of the year. Pharvaris says it plans to request an end-of-Phase 2 meeting with the agency soon, and it is preparing for RAPIDe-3, a global Phase 3 study of deucrictibant for the on-demand treatment of HAE.
HAE is a rare inherited disorder where fluids accumulate outside of the blood vessels, blocking the normal flow of blood or lymphatic fluid and causing rapid swelling of tissues in the hands, feet, limbs, face, intestinal tract, or airway.
Deucrictibant is said to utilize the same mechanism of action as Takeda’s Firazyr (icatibant), which Pharvaris says is the leading therapy for on-demand treatment of HAE. “Data from single- and multiple-ascending-dose Phase 1 studies in healthy volunteers demonstrate rapid exposure and predictable linear pharmacokinetics at doses up to 50 mg,” it says. “Quantitative modeling indicates that single oral doses of [deucrictibant] will maintain pharmacologically active drug levels for a substantially longer time than 30 mg of subcutaneous icatibant.”
