Hemophilia A Clinical Trial
Official title:
A Phase 2a Study of Ataluren (PTC124) as an Oral Treatment for Nonsense-Mutation-Mediated Hemophilia A and B
Hemophilia A (HA) and hemophilia B (HB) are inherited bleeding disorders caused by mutations in the gene for factor VIII (FVIII) and factor IX (FIX), respectively. These proteins are essential for blood clotting. The lack of FVIII/FIX can produce bleeding episodes that cause damage of the bone, muscles, joints, and tissues. A specific type of mutation, called a nonsense (premature stop codon) mutation, is the cause of the disease in approximately 10-30% of participants with hemophilia and results in severe manifestations. Ataluren (PTC124) is an orally delivered, investigational drug that acts to overcome the effects of the premature stop codon, potentially enabling the production of functional FVIII/FIX. This study is a Phase 2a trial evaluating the safety and efficacy of ataluren in participants with HA or HB due to a nonsense mutation. The main purpose of this study is to understand whether ataluren can safely increase FVIII/FIX activity levels.
In this study, participants with hemophilia A or hemophilia B due to a nonsense mutation were treated with an investigational drug called ataluren (PTC124). Evaluation procedures to determine if a participant qualifies for the study was performed within 14 days prior to the start of treatment. Eligible participants who elected to enroll in the study then participated in a 28-day treatment period. Within the 28-day period, ataluren (PTC124) treatment was to be taken for 2 cycles of 14 days each 3 times per day with meals at a dose level of 5, 5, 10 milligrams/kilograms (mg/kg) in the first cycle and a dose level of 20, 20, 40 mg/kg in the second cycle. After the first 14-day cycle, study doses were changed to 10 mg/kg (morning), 10 mg/kg (midday), and 20 mg/kg (evening) and the doses were administered for 1 cycle only. Then, there was an interval of approximately 14 days without treatment. During the study, ataluren (PTC124) efficacy, safety, and pharmacokinetics were evaluated periodically with measurement of FVIII/FIX activity and inhibitor levels, other blood tests, and urinalysis. ;
