NCT ID: NCT03547297 Terminated - Clinical trials for Acute Hepatic Porphyria

INSIGHT-AHP: A Study to Characterize the Prevalence of Acute Hepatic Porphyria (AHP) in Patients With Clinical Presentation and History Consistent With AHP

Start date: May 29, 2018
Phase:
Study type: Observational

This study will use specific diagnostic tests on a group of patients who are experiencing symptoms typical of acute hepatic porphyria (AHP) to determine how many have the condition, and to potentially help improve the diagnostic process for patients in the future.

NCT ID: NCT03338816 Completed - Clinical trials for Acute Intermittent Porphyria

ENVISION: A Study to Evaluate the Efficacy and Safety of Givosiran (ALN-AS1) in Patients With Acute Hepatic Porphyrias (AHP)

Start date: November 16, 2017
Phase: Phase 3
Study type: Interventional

The purpose of this study is to evaluate the effect of subcutaneous givosiran (ALN-AS1), compared to placebo, on the rate of porphyria attacks in patients with Acute Hepatic Porphyrias (AHP).

NCT ID: NCT01568554 Completed - Clinical trials for Acute Intermittent Porphyria (AIP)

Clinical Diagnosis of Acute Porphyria

Start date: December 2011
Phase:
Study type: Observational

The purpose of this study is to test whether a focused questionnaire and laboratory tests can better define risk factors associated with possible genetic porphyria. The investigators hypothesize that the genetic carrier state of acute porphyria is distinctive enough that the Genetic Carrier Profile the investigators devise through this study will be useful in identifying carriers of genetic porphyria among the large population with undiagnosed abdominal pain.
