Fast Track Granted for Pancreatic Cancer Drug
FDA has granted Theriva Biologics a fast-track designation for its lead clinical candidate VCN-01 in combination with gemcitabine and nab-paclitaxel to improve progression-free survival and overall survival in patients with metastatic pancreatic adenocarcinoma.
VCN-01 is described by the company as a systemically administered oncolytic adenovirus designed to “selectively and aggressively replicate within tumor cells and degrade the tumor stroma that serves as a significant physical and immunosuppressive barrier to cancer treatment. This unique mode of action enables VCN-01 to exert multiple antitumor effects by (i) selectively infecting and lysing tumor cells; (ii) enhancing the access and perfusion of co-administered chemotherapy products; and (iii) increasing tumor immunogenicity and exposing the tumor to the patient’s immune system and co-administered immunotherapy products.”
Theriva says the therapy has been administered to over 80 patients in Phase 1 and investigator-sponsored clinical trials of different cancers, including pancreatic ductal adenocarcinoma (PDAC) in combination with chemotherapy, head and neck squamous cell carcinoma (with an immune checkpoint inhibitor), ovarian cancer (with CAR-T cell therapy), colorectal cancer, and retinoblastoma (by intravitreal injection).
Currently, VCN-01 is being evaluated in VIRAGE, a multinational Phase 2b clinical study, in combination with standard-of-care chemotherapy (gemcitabine/nab-paclitaxel) as a first-line therapy for patients with PDAC. Previously, the agency granted an orphan drug designation to VCN-01 for treating PDAC.
