| | SAN DIEGO, Nov. 9, 2021 /PRNewswire/ -- Poseida Therapeutics, Inc. (Nasdaq: PSTX), a clinical-stage biopharmaceutical company utilizing proprietary genetic engineering platform technologies to create cell and gene therapeutics with the capacity to cure, today announced program updates and financial results for the third quarter ended September 30, 2021. “The last quarter saw continued progress as Poseida reached multiple key strategic milestones including FDA clearance of our first fully allogeneic CAR-T IND for P-BCMA-ALLO1, the presentation of strong CAR-T data in a solid tumor indication with our P-PSMA-101 program and, shortly after the quarter, the announcement of a strategic collaboration with Takeda focused on non-viral in vivo gene therapy programs utilizing our platform technologies,” said Eric Ostertag, M.D., Ph.D., Chief Executive Officer of Poseida. “The initiation of our P-BCMA-ALLO1 clinical trial represents the beginning of a long-planned strategic transition to what we believe is the ‘holy grail’ of cell therapy for oncology, a fully allogeneic CAR-T with a fully humanized heavy chain BCMA binder and a high percentage of TSCM cells which we believe are the key to success,” continued Ostertag. “While we believe the P-BCMA-101 autologous program has competitive advantages and would be approvable, one long-term strategic benefit of that program has been to inform our highly-differentiated allogeneic approach. With the P-BCMA-ALLO1 clinical program now underway and with very high confidence in our allogeneic platform, we will begin a planned wind down of P-BCMA-101.” Program Updates BCMA Program
P-BCMA-ALLO1, the Company’s first fully allogeneic CAR-T product candidate, is in development for the treatment of relapsed/refractory multiple myeloma. In August of 2021, the U.S. Food and Drug Administration (FDA) cleared the Investigational New Drug (IND) application for P-BCMA-ALLO1. The IND clearance and the start-up of the Phase 1 clinical trial mark the beginning of the Company’s strategic shift toward focusing on P-BCMA-ALLO1 rather than the autologous P-BCMA-101 program. While data in the autologous trial showed meaningful responses and a favorable safety profile, the Company’s strategic focus has long been on allogeneic CAR-T therapies, leveraging the learnings of the autologous CAR-T program to provide benefits beyond those of autologous CAR-T, including a more desirable off-the-shelf product profile for future commercialization while maintaining the tolerability advantage of our autologous product candidate. P-BCMA-ALLO1 has the potential to deliver up to hundreds of doses per manufacturing run, thereby dramatically reducing both clinical trial costs and ultimately commercial product cost compared to the autologous P-BCMA-101 program. PSMA Program
P-PSMA-101 is a solid tumor autologous CAR-T product candidate being developed to treat patients with metastatic castrate-resistant prostate cancer (mCRPC) currently in an ongoing Phase 1 dose escalation trial. In August of 2021, the Company presented preliminary data at the 6th Annual CAR-TCR Summit virtual meeting that demonstrated meaningful patient responses while maintaining a favorable safety and tolerability profile with modest overall rates of CRS and no neurotoxicity observed at low doses. An additional update on the P-PSMA-101 program is expected in the first half of 2022. MUC1-C Program
P-MUC1C-ALLO1 is an allogeneic CAR-T product candidate in preclinical development with the potential to treat a wide range of solid tumors, including breast and ovarian cancers. P-MUC1C-ALLO1 is proceeding, with an anticipated IND filing and initiation of a Phase 1 clinical trial by the end of 2021. Liver-Directed Gene Therapy Program
P-OTC-101 is the Company’s first liver-directed gene therapy program for the in vivo treatment of urea cycle disease caused by congenital mutations in the ornithine transcarbamylase (OTC) gene, a condition characterized by high unmet medical need. The Company is currently evaluating whether to modify the P-OTC-101 program to move to the fully non-viral nanoparticle delivery system. The Company will update expected timing on program advancement once that evaluation is complete. Other Operational Updates and Upcoming Events Gene Therapy Research Collaboration with Takeda
In October of 2021, the Company entered into a collaboration and license agreement with Takeda Pharmaceuticals USA, Inc. to utilize Poseida’s proprietary genetic engineering platforms for the research and development of up to eight gene therapies. The collaboration will focus on developing non-viral in vivo gene therapy programs, including Poseida’s Hemophilia A program. The Company will receive an upfront payment of $45.0 million, of which $5.0 million is for prepaid research. Per the agreement, Takeda will fund all ongoing partnered program research performed by Poseida. The collaboration may utilize all of Poseida’s novel genetic engineering platform technologies, including the piggyBac® DNA Modification System for gene addition, the Cas-CLOVER™ Site-specific Gene Editing System for ultra-precise gene editing, biodegradable nanoparticle technologies for gene delivery and other emerging technologies. Poseida will lead research activities up to candidate selection, after which Takeda will assume responsibility for further development and commercialization. GMP Facility
In the third quarter, the Company completed qualification and commenced GMP activity in its internal pilot manufacturing plant. The pilot plant is designed to support and speed the development of allogeneic product candidates including manufacturing clinical material for early-stage trials. The first product candidate to be produced out of the pilot plant will be P-MUC1C-ALLO1. Society for Immunotherapy of Cancer (SITC) 36th Annual Meeting
The Company will give two virtual poster presentations at the upcoming SITC Annual Meeting, being held in Washington, D.C., and virtually November 10-14, 2021. The full abstracts were made available on the SITC website earlier today, with presentations taking place on November 12, 2021. 63rd American Society of Hematology (ASH) Annual Meeting and Exposition
The Company will present data from the Company’s differentiated P-BCMA-101 autologous CAR-T program including how it has informed the P-BCMA-ALLO1 allogeneic CAR-T program in a poster publication at the ASH Annual Meeting on Monday, December 13, 2021: Session Name: 704. Cellular Immunotherapies: Clinical: Poster III
Presentation Time: 6:00 PM - 8:00 PM Eastern time
Location: Georgia World Congress Center, Hall B5 Financial Results for the Third Quarter 2021 Research and Development Expenses
Research and development expenses were $32.5 million for the third quarter ended September 30, 2021, compared to $27.0 million for the same period in 2020. For the nine months ended September 30, 2021, research and development expenses were $97.6 million, compared to $75.6 million for the same period in 2020. The increase was primarily due to increased stock-based compensation expense, headcount, external costs related to our preclinical programs and clinical stage programs, including the ongoing enrollment and manufacturing associated with our P-BCMA-101, P-BCMA-ALLO1 and P-PSMA-101 clinical trials, and internal costs related to facilities development. General and Administrative Expenses
General and administrative expenses were $9.1 million for the third quarter ended September 30, 2021, compared to $6.5 million for the same period in 2020. General and administrative expenses were $26.3 million for the nine months ended September 30, 2021, compared to $15.6 million for the same period in 2020. The increase was primarily due to increased stock-based compensation expense, headcount, insurance costs and professional fees. Net Loss
Net loss was $42.4 million and $126.4 million for the three and nine months ended September 30, 2021, respectively, and $34.4 million and $93.6 million for the three and nine months ended September 30, 2020, respectively. Cash Position
As of September 30, 2021, our cash and cash equivalents balance was $197.8 million. About Poseida Therapeutics, Inc.
