Lentiviral Gene Therapy for CGD

Chronic Granulomatous Disease

Chronic granulomatous disease, Lentiviral vector

This is a Phase I/II clinical trial of gene therapy for treating Chronic Granulomatous Disease using a high-safety, high-efficiency, self-inactivating lentiviral vector TYF to functionally correct the defective gene. The objectives are to evaluate the safety and efficacy of the TYF-CGD gene transfer clinical protocol.

Neither the sponsor Beijing Meikang Jimian Biotechnology Co., Ltd. nor collaborator Shenzhen Geno-Immune Medical Institute has obtained NMPA clinical trial approval or clinical technology filing permission to carry out interventional cell therapy trials in mainland China. ClinicalTrials.gov registration alone does not represent legal approval by Chinese health and drug regulatory authorities. Chronic granulomatous disease (CGD) is a rare disorder caused by inherited defects in the NADPH oxidase multienzyme complex. It is associated with severe and life-threatening bacterial and fungal infections. Approximately two-thirds of all CGD cases result from mutations within the X-linked gp91phox gene (CYBB), followed by the autosomal recessive forms of CGD, with defects in the gene coding for p47phox (NCF1) accounting for 10-30% of all CGD cases. The primary objectives are to evaluate the safety of the advanced self-inactivating lentiviral vector TYF-CYBB and TYF-NCF1, the ex-vivo gene transfer clinical protocol and the efficacy of immune reconstitution in patients overcoming frequent infections present at the time of treatment, assessment of vector integration sites, and finally the long-term correction of immune dysfunctions.
