Current protocol of a research phase I clinical trial of full-length dystrophin plasmid DNA in Duchenne/Becker muscular dystrophies. Part II: clinical protocol.
A phase I open clinical study on gene therapy in Duchenne and Becker muscular dystrophy, without direct individual benefit for the patient, is being performed at the Pitié-Salpêtrière Hospital, Paris. The aims of this project are: (a) to determine the tolerance and the safety of the intramuscular administration of dystrophin cDNA and (b) to study the quality of the gene transfer in vivo in human patients affected by Duchenne and Becker muscular dystrophy. This clinical trial is conducted sequentially and includes three cohorts of three patients each. Patients must be at least 15 years of age. Diagnosis of Duchenne and Becker muscular dystrophy was confirmed by molecular analysis of the dystrophin gene and for each patient the abnormal expression of dystrophin was confirmed, in skeletal muscle, with antibodies directed against the deleted part of the dystrophin. This phase I study is scheduled to be completed by the end of 2002.
