enGene Holdings Inc. is a holding company. The Company, through its subsidiary, enGene Inc., is engaged in developing non-viral gene therapies based on localized delivery of nucleic acid payloads to mucosal tissues. The Company’s proprietary dually derived chitosan (DDX) platform has a high degree of payload flexibility, including DNA and various forms of RNA with broad tissue and disease application. In preclinical animal and in vitro models, the Company’s DDX technology has been demonstrated to effectively induce expression of therapeutic genes following delivery to the lung, gastrointestinal tract, and urinary tract, and its lead product detalimogene voraplasmid (EG-70) is being developed for the treatment of bacillus calmette-guerin (BCG)-resistant non-muscle invasive bladder cancer (NMIBC) with carcinoma in situ (CIS). EG-70 is a novel non-viral gene therapy designed to elicit a local immune response following the delivery to the bladder urothelium.
