Poseida Therapeutics

Poseida Therapeutics is a privately held, biopharmaceutical company based in San Diego California. It leverages proprietary non-viral, gene engineering technologies to create therapeutics for illnesses with high unmet medical needs. The company is developing a wholly-owned pipeline of autologous and allogenic CAR-T product candidates, initially focused on the treatment of hematological malignancies and other solid tumors.

Poseida's leading product candidate is P-BCMA-101, an autologous CAR-T product that targets B cell maturation antigen, or BCMA, which is expressed on multiple myeloma cells. In December 2018, the company announced positive results from its first cohort of ongoing Phase 1 clinical trial. Poseida's second autologous product is P-PSMA-101, targeting cells that express prostate-specific membrane antigen, which is expressed on most prostate cancer cells. The product is being developed to treat patients with castrate-resistance prostate cancer, or CRPC, a solid tumor indication, with Phase 1 clinical trials planned in the second half of 2019.

Under the allogenic category, Poseida has P-BCMA-ALL01 and P-MUC1C-101. Derived from healthy donors, P-BCMA-ALL01 is designed to have the same inherent properties and functions of P-BCMA-101, but with the benefits of scale and administration efficiency that come from an allogenic product. The company plans to file an IND and begin Phase 1 clinical trials by late 2019 or early 2020. As for P-MUC1C-101, the product is in late-stage pre-clinical development for multiple solid tumor indications with plans for Phase 1 clinical trials in 2020.

In January 2019, Poseida Therapeutics filed documents for an IPO of $115 million.
