Implementing enhancements to ongoing allogeneic programs based upon significant learnings; adjusting guidance on clinical data updates
Extending cash runway guidance
"We are excited to announce a strategic investment by Astellas, a premier global pharmaceutical company that shares our strategic vision for the future of genetic engineering and cell and gene therapies. This investment further validates our technology and approach and also reflects our broad strategic options in progressing the business," said Mark Gergen, Poseida's Chief Executive Officer. "Based on this investment and cost control measures implemented in the business, we are extending our cash runway guidance as we remain focused on being good stewards of capital. As we look towards the future, we are taking recent learnings from our allogeneic programs and implementing improvements across our clinical trials. Based on these findings, we are adjusting guidance on data updates and look forward to sharing clinical data highlighting some of these enhancements at a medical meeting later this year, with plans for a more robust clinical update to follow in mid-2024."
Allogeneic CAR-T Program Updates & Clinical Trial Learnings
"We are continuing to advance the Phase 1 trials for both P-BCMA-ALLO1 and P-MUC1C-ALLO1 and the data we have generated has led us to find improvements that we believe have the potential to greatly benefit our allogeneic portfolio," added Kristin Yarema, Ph.D., President of Cell Therapy at Poseida. "We have implemented a number of these already in our clinical-stage programs, as we continue steady progress in dose-ranging and explore approaches such as raising conditioning lymphodepletion to emerging industry norms and exploring additional dosing and administration options. We are also improving our manufacturing process in ways that will further increase product yield, and are encouraged by the early signals we are seeing in this area also. Overall, we remain highly excited about the potential of our allogeneic platform and our ongoing opportunities for continuous improvement."
P-BCMA-ALLO1
P-BCMA-ALLO1 is an allogeneic CAR-T product candidate being developed to target relapsed/refractory multiple myeloma (R/R MM) in partnership with Roche. The Company is currently evaluating P-BCMA-ALLO1 in a Phase 1 clinical trial and expects to present a clinical update for the program at a medical meeting in 2023, subject to clearance with Roche. Given the implementation of new dosing regimens, the Company expects that there will be a limited number of patients available for evaluation in newer cohorts. Poseida plans to provide a further clinical update in mid-2024.
P-MUC1C-ALLO1
P-MUC1C-ALLO1 is an allogeneic CAR-T product candidate targeting solid tumors derived from epithelial cells, including breast and ovarian cancers. The Company is currently evaluating P-MUC1C-ALLO1 in a Phase 1 clinical trial. The Company expects to present clinical updates for the program at a medical meeting in 2023. Given the implementation of new dosing regimens, the Company expects that there will be a limited number of patients available for evaluation in newer cohorts. Poseida plans to provide a further clinical update in mid-2024.
P-CD19CD20-ALLO1
P-CD19CD20-ALLO1 is an allogeneic CAR-T product being developed to target B-cell malignancies in partnership with Roche. P-CD19CD20-ALLO1 is the Company's first dual CAR program and contains two fully functional CAR molecules to target cells that express either CD19 or CD20. The Company believes that by targeting both CD19 and CD20, there is potential to overcome antigen escape that has been observed by others. In June 2023 Poseida received IND clearance from the FDA for P-CD19CD20-ALLO1, which the Company believes is the first allogeneic dual CAR-T therapy targeting CD19 and CD20 antigens that has received such clearance, and has initiated site start-up for this program. Poseida expects to dose the first patient with P-CD19CD20-ALLO1 in early 2024.
Gene Therapy Programs
As previously announced, Poseida's gene therapy collaboration with Takeda was terminated in July 2023. The Company is in the process of evaluating both the returning Takeda programs and its internal gene therapy programs to determine which programs it will prioritize and progress internally. In addition, the Company is actively evaluating the potential to leverage these gene therapy programs through business development. The Company intends to provide an update on this evaluation when complete.
In July 2023 the FDA granted orphan drug designation to P-OTC-101, an in vivo program for the treatment of urea cycle disease caused by congenital mutations in the ornithine transcarbamylase (OTC) gene. The Company is developing the P-OTC-101 program utilizing a hybrid delivery system and working on an updated timeline for the program.
Financial Guidance Update
"The strategic investment by Astellas, together with our disciplined capital expenditure, cost control initiatives and expected payments and milestones from the Roche collaboration, put us on a firm financial foundation," said Johanna Mylet, Chief Financial Officer of Poseida. "With these updates we have extended our cash runway based upon current plans into early 2025. In addition, we believe that further upside from our Roche collaboration as well as potential business development opportunities provide additional confidence as we enter the second half of 2023."
