Filter by: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).
The purpose of this study is to determine the long-term safety, tolerability and pharmacokinetics of givosiran (ALN-AS1) in AIP patients who completed study ALN-AS1-001 (NCT02452372).
Cycle Pharmaceuticals Ltd. (Cycle) is developing an oral tablet formulation of Chlorpromazine Hydrochloride and intends to conduct bioequivalence trials to demonstrate its similarity to the RLD. The aim of this pilot study is to investigate intrasubject variability in the bioavailability of Chlorpromazine Hydrochloride 25 mg sugar coated tablets. Cycle aims to demonstrate that Chlorpromazine Hydrochloride has a shallow dose response curve and a wide safety margin. This will then allow for the modification of bioequivalence acceptance criteria in future pivotal studies which will reduce the number of participants required whilst still maintaining assurance of safety and efficacy. Pilot Subjects (n): 20 Periods: 2 (2xR) Dosing: Single-dose Strength: 25 mg Test Product: N/A Reference: USL PHARMA Chlorpromazine Hydrochloride Analytes (in plasma): Chlorpromazine; 7-Hydroxychlorpromazine Bioequivalence based on 90% CI (Cmax, AUC): Standard; 80.00 - 125.00%
The purpose of this study is to evaluate the safety and tolerability of givosiran (ALN-AS1) in AIP patients as well as to characterize pharmacokinetics (PK) and pharmacodynamics (PD) of ALN-AS1 in AIP patients.
This is a Phase I trial aimed to determine the safety of the investigational gene therapy product (rAAV2/5-PBGD) for the treatment of Acute Intermittent Porphyria (AIP). Up to eight patients fulfilling the eligibility criteria will participate in this multicentre, open label, single dose, dose-ranging Phase I clinical trial. The enrolled patients will be followed up to assess the safety profile of the investigational gene therapy product and to establish the maximum therapeutic safe dose to be administered in future confirmatory/pivotal clinical trial(s). In addition, the biological and clinical response to the treatment with rAAV2/5-PBGD in AIP patients will be assessed. A complete evaluation of the clinical (symptoms and quality of life assessment) and laboratory (blood and urine) data will be performed.
This is an observational prospective study that will allow evaluating the clinical and laboratory parameters evolution of at least eight patients with AIP. This study will allow establishing a baseline for the evaluation of the eight patients that are planned to be included in a gene therapy clinical trial (AAVPBGD-AIP-001) for the AIP treatment using a rAAV5-AAT-cohPBGD expression. Patients fulfilling the study inclusion criteria will undergo a clinical and laboratory evaluation for a minimum of 6 months (with one inclusion visit, one final visit and at least two visits of follow up) up to a maximum of 24 months until their inclusion in the subsequent clinical trial. A complete evaluation of the clinical (symptoms and quality of life assessment) and laboratory (blood and urine) data will be collected.
A multi-centre, double-blind, randomized, placebo controlled, parallel group trial, investigating the efficacy and safety of Porphozym (recombinant human porphobilinogen deaminase)in the treatment of acute attacks in AIP.
