This is a first-in-humans gene therapy study for subjects diagnosed with severe hemophilia A. A one time infusion of the gene therapy product (BAX888) will be given with the hope of eliminating or reducing the need for prophylactic and/or on-demand use of FVIII concentrate therapy. Up to 10 subjects will be enrolled study-wide with up to two subjects enrolled at MUSC. This study will require weekly visits to the study clinic after initial infusion for the first 15 weeks followed by monthly visits for the first year. Compensation will be provided.
Patients with hereditary blood clotting protein deficiencies of Factor VIII (diagnosis of Hemophilia A) and FIX deficiency (diagnosis of Hemophilia B) will be asked to donate a blood sample to test new reagents from Stago to replace the ones currently used in our laboratory to measure the levels of these clotting factors in plasma. In part one of the study sample once drawn and processed will be immediately have levels of either FVIII or Factor IX measured and then the assay repeated hourly for the next 5 hours to assess sample stability (reproducibility). The purpose of this part of the study is validate the sample stability at room temperature known from the literature described in CLSL guideline. In part two of the study, aliquots of the same samples will be frozen at both -20C and -80C. The -20C samples will be thawed at day 7, 15 and 17 and the Factor VIII and Factor IX assays repeated. The -80C samples will be thawed at days 15, 30 and 32 and the assays repeated. The purpose of this part of the study is to validate the sample stability after freezing at -20C and -80C known from the literature and recognized by CLSI.
This trial is a first-in-human clinical trial with subcutaneous injections of turoctocog alfa pegol (N8-GP). You must be male, age 12 or older with a diagnosis of hemophilia A to participate. The purpose of the trial is to investigate the potential effect of N8-GP
on prevention of bleeds in previously treated patients with severe hemophilia A. This study would require approximately 10 visits to the research clinic over 5 months. Compensation will be provided for time and travel.
The purpose of this research trial is to find out how effective a new Factor VIII (FVIII) product called N8-GP is in prevention and treatment of bleeding episodes, and to find out if there are any unwanted effects related to its use.
