SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--Arsenal Biosciences, Inc. (ArsenalBio), a privately held, clinical stage, programmable cell therapy company engineering advanced CAR T cell therapies for solid tumors, today announced that the first patient has been dosed with AB-1015 in a Phase 1, first-in-human clinical trial for patients with ovarian cancer that is resistant to platinum-based regimens. AB-1015 is ArsenalBio’s first internally discovered T cell medicine to enter clinical development and uses synthetic DNA programming to overcome tumor defenses, increase potency, and target ovarian cancer cells without harming normal tissues.

“The initiation of this first-in-platform trial marks the beginning of a new chapter in the story of cell therapy and will enable ArsenalBio to validate our Integrated Circuit T (ICT) cell technology in humans,” said Ken Drazan, M.D., ArsenalBio’s co-founder and Chief Executive Officer. “To date, first generation T cell-based technologies have failed to drive deep and durable responses in solid tumors, leaving a large unmet need for effective immunotherapies across many types of solid tumor cancers. We hope this study succeeds in identifying a safe and therapeutic dose to further study in larger patient cohorts; thereby demonstrating the utility of our technology platform and the benefit of our pipeline of potential medicines.”

Dr. Drazan will provide a business overview and update inclusive of information about the clinical trial during the company’s upcoming presentation on January 10th at the 41st Annual J.P. Morgan Healthcare Conference.

The Phase 1 trial (NCT05617755) is a multi-center, dose escalation trial that will evaluate the safety of AB-1015 in patients with platinum-resistant ovarian cancer. The goal of the study is to determine the maximum tolerated dose of AB-1015, which is administered intravenously via a single infusion following completion of lymphodepleting chemotherapy. The study is expected to enroll up to 60 patients in the United States.

“Immunotherapy offers great promise for ovarian cancer patients who have already failed or relapsed following treatment with platinum-based chemotherapies because it uses the patient’s own immune cells to kill cancer cells,” said Susie Jun, M.D., Ph.D., ArsenalBio’s Chief Medical Officer. “Following our AB-1015 study, we plan to initiate subsequent clinical studies to explore the use of our ICT cell technology in other solid tumor cancers with high unmet medical need including kidney and prostate cancers.”

AB-1015 is an ICT cell therapy engineered to treat ovarian cancer. The foundational manufacturing technique is precise and specific CRISPR insertion of a large synthetic double-stranded DNA cassette into a novel Chromosome 11 safe harbor site. The cassette encodes several features: a synthetic logic gate designed to optimize how the ICT cells target tumors and avoid normal tissues by requiring the co-expression of two distinct antigens within ovarian cancer; and a module containing synthetic short hairpin RNAs designed to pharmacologically modulate gene expression thus enabling enhanced T cell function in the tumor microenvironment.
