Anixa Biosciences Treats Sixth Patient in its Ovarian Cancer CAR-T Trial

Anixa Biosciences (NASDAQ:ANIX), Inc. (ANIX), a biotechnology company focused on the treatment and prevention of cancer, today announced that it has treated the sixth patient in the ongoing Phase 1 clinical trial of its novel chimeric antigen receptor T-cell (CAR-T) therapy for ovarian cancer. This patient is expected to be the last patient in the second dosage cohort. If there continue to be no adverse effects experienced by the second cohort participants, enrollment of the third dosage cohort may commence within the next month. The study is being conducted through a research partnership with Moffitt Cancer Center.

Anixa's FSHR-mediated CAR-T technology, also known as chimeric endocrine receptor T-cell (CER-T), differs from traditional CAR-T therapy by targeting the follicle-stimulating hormone receptor (FSHR), which research indicates is exclusively expressed on ovarian cells, including the vasculature of tumors. The first-in-human trial (NCT05316129) is enrolling female adult patients with recurrent/progressing ovarian cancer who have progressed on at least two prior therapies. The study is designed to evaluate safety and identify the maximum tolerated dose, while monitoring efficacy.

Safety was previously confirmed in the first three-patient cohort. The fourth through sixth patients, enrolled in the second cohort of the Phase 1 clinical trial, received triple the dose of CAR-T cells compared with the dose of the first cohort, with no dose-limiting toxicities observed.

Following the requisite wait time, of one month after dosing, enabling confirmation that it is safe to escalate, the trial will immediately begin enrolling patients in the third dose cohort, which will be at a ten times higher dose than the initial dosage.

Dr. Amit Kumar, Chairman and CEO of Anixa Biosciences, stated, "We are highly encouraged by the favorable safety profile observed thus far in both the first and second patient cohorts, and are eager to evaluate a higher dose in the next cohort. We are particularly encouraged by a notable response in one of the patients in the first cohort, even though the dosage was considered a subtherapeutic level. Our aim is to maintain a positive safety profile as we escalate dosing, with the goal of demonstrating additional objective evidence of efficacy. Unlike conventional CAR-T cell therapies, which have achieved amazing results in various hematological cancers, they have not been effective in solid tumors. In contrast, we believe Anixa's novel technology has the potential to make CAR-T effective in ovarian cancer and perhaps across multiple solid tumor types. Our unique and highly targeted CER-T approach targets the FSHR, which is exclusively expressed on ovarian cells. A potential dual mechanism of action is operating with our therapy targeting tumor vasculature by starving or shrinking the tumor from the inside out, as well as direct targeting of ovarian cells."

Dr. Kumar continued, "We believe that intraperitoneal (IP) delivery may also be a significant advantage of our therapy, as it allows direct trafficking of the CAR-T cells to the tumor sites, which helps to minimize side effects such as cytokine release syndrome (CRS). We believe this method of delivery not only enhances the targeting of the tumor but also improves the overall safety profile of the treatment. We expect that IP delivery may enable us to use dosages that are much higher than possible with intravenous delivery."
