NCT ID: NCT06343779 Recruiting - Clinical trials for Hereditary Angioedema

Study of Oral Deucrictibant Soft Capsule for On-Demand Treatment of Angioedema Attacks in Adolescents and Adults With Hereditary Angioedema

RAPIDe-3
Start date: February 26, 2024
Phase: Phase 3
Study type: Interventional

This is a Phase 3, multicenter, randomized, double-blind, placebo-controlled, 2-period, 2-treatment cross-over study to evaluate the efficacy and safety of orally administered deucrictibant compared to placebo for the on-demand treatment of HAE attacks, including non-severe laryngeal attacks, in participants ≥12 to ≤75 years of age with HAE type 1 or type 2 (HAE-1/2), a proportion of whom are using long-term prophylactic medication for HAE.

NCT ID: NCT06210698 Not yet recruiting - Urticaria Clinical Trials

Angioedema Biomarker Research Study

Start date: January 15, 2024
Phase:
Study type: Observational

This clinical trial aims to evaluate and compare novel and commercially available diagnostic assays through blood tests for the differential diagnosis and comprehensive assessment of patients experiencing recurrent angioedema attacks, including both urticarial and non-urticarial angioedema. The primary objective is to assess the efficiency of novel diagnostic assays, both individually and in combination, in comparison to currently available commercial tests. The ultimate goal is to establish the feasibility of developing an affordable and accurate laboratory test capable of diagnosing the diverse etiological manifestations of angioedema.

NCT ID: NCT05396105 Recruiting - Clinical trials for Hereditary Angioedema

Extension Study of Oral PHA-022121 for Acute Treatment of Angioedema Attacks in Patients With Hereditary Angioedema

RAPIDe-2
Start date: December 28, 2022
Phase: Phase 2/Phase 3
Study type: Interventional

This study evaluates the safety and efficacy of long-term on-demand treatment with orally administered deucrictibant for acute hereditary angioedema (HAE) attacks, including laryngeal attacks, in patients with HAE due to C1-esterase inhibitor (C1-INH) deficiency (type I/II). The study will enroll patients from Study PHA022121-C201 (NCT04618211) who elect to participate in this extension study and meet the eligibility requirements.

NCT ID: NCT05047185 Active, not recruiting - Clinical trials for Hereditary Angioedema

Dose-ranging Study of Oral PHA-022121 for Prophylaxis Against Angioedema Attacks in Patients With Hereditary Angioedema Type I or Type II

HAE CHAPTER-1
Start date: April 19, 2022
Phase: Phase 2
Study type: Interventional

This study evaluates the safety and efficacy of PHA-022121 administered orally for prophylaxis against angioedema attacks in patients with hereditary angioedema (HAE). The study consists of 2 parts, with patients completing participation in Part 1 prior to initiation of treatment in Part 2. Part 1 of the study has 3 parallel arms and approximately 30 patients will be equally randomized to one of two dose regimens of PHA-022121 or matching placebo. Patients will continue to the single open-label arm in Part 2 of the study after completion of Part 1. The screening period is up to 8 weeks and the treatment periods are 12 weeks (Part 1) and 30 months (Part 2) in duration.

NCT ID: NCT04618211 Completed - Clinical trials for Hereditary Angioedema

Dose-ranging Study of Oral PHA-022121 for Acute Treatment of Angioedema Attacks in Patients With Hereditary Angioedema

RAPIDe-1
Start date: February 3, 2021
Phase: Phase 2
Study type: Interventional

This study evaluates the efficacy of orally administered deucrictibant for the acute treatment of attacks in patients with hereditary angioedema (HAE). Eligible subjects are randomized to one of three single doses of deucrictibant and placebo. The study will compare symptom relief (skin pain, skin swelling, abdominal pain) during HAE attacks and safety of each dose of deucrictibant with placebo.
