Lentiviral FVIII Gene Therapy for Hemophilia A
This study is a Phase I trial using an advanced lentiviral vector to deliver a functional gene for human clotting factor VIII into patients with hemophilia A, to evaluate the safety and efficacy of infusion of lentiviral gene modified autologous stem cells in patients.
Inclusion: Able to provide informed consent and comply with requirements of the study; Males ≥2 years with confirmed diagnosis of hemophilia A (endogenous factor VIII ≤2 IU/dL or ≤2% of normal); A minimum average of 4 bleeding events per year requiring episodic treatment of factor VIII infusions or prophylactic factor VIII infusions; No measurable factor VIII inhibitor as assessed by the central laboratory and have no prior history of inhibitors to factor VIII protein; Agree to use reliable barrier contraception until 3 consecutive samples are negative for vector sequences.
Exclusion: Evidence of active hepatitis B or C and currently on antiviral therapy; Participated in a gene transfer trial within the last 6 months or in a clinical trial with an investigational drug within the last 12 weeks; History of inhibitor against factor VIII; Any evidence of active infection or any immunosuppressive disorder; Significant liver dysfunction as defined by abnormal alanine transaminase, bilirubin and alkaline phosphatase; Have serological evidence of HIV-1 or HIV-2 with CD4 counts ≤200/mm3 (subjects who are HIV+ and stable with CD4 count >200/mm3 and undetectable viral load are eligible to enroll); Unable or unwilling to comply with study assessments.
