Allogeneic, TSCM-rich dual CAR-T
for the treatment of hematologic malignancies, including multiple
myeloma

million milestone payment to Poseida, extending cash runway

DIEGO, Oct. 17, 2024 /PRNewswire/ -- Poseida
Therapeutics, Inc. (Nasdaq: PSTX), a clinical-stage allogeneic cell
therapy and genetic medicines company advancing differentiated
non-viral treatments for patients with cancer, autoimmune, and rare
diseases, today announced the nomination of a new development
candidate under its collaboration with Roche. The nomination
triggered a $15 million milestone
payment from Roche to Poseida.
The new candidate is an allogeneic, dual CAR-T therapy targeting
known antigens expressed in hematologic malignancies, including
multiple myeloma. The large capacity of Poseida's non-viral
transposon-based DNA delivery system enables the insertion of genes
for two full length chimeric antigen receptors (CARs) into T stem
cell memory cells (TSCM).
"The nomination of a new development candidate builds on our
collaboration with Roche and highlights the unique potential of our
proprietary non-viral genetic engineering toolkit to create
differentiated, TSCM-rich allogeneic CAR-T therapies
targeting one or more antigens," said Kristin Yarema, Ph.D., president and chief
executive officer of Poseida Therapeutics. "Multiple myeloma
is a common and incurable blood cancer with significant room for
potent, safe and accessible novel agents to expand use across lines
of therapy and sites of care. With compelling preclinical data
supporting the target combination of this dual CAR-T, we look
forward to advancing this program towards the clinic as a part of
the collaboration. We also look forward to providing updates on our
CAR-T programs and earlier-stage pipeline at Poseida's upcoming
Cell Therapy R&D Day."
Poseida and Roche now have three programs under their
collaboration, which was established in August 2022 to develop allogeneic CAR-T therapies
directed to hematologic malignancies. The lead collaboration
program, P-BCMA-ALLO1, is an allogeneic CAR-T therapy targeting
BCMA that has received Regenerative Medicine Advanced Therapy
(RMAT) designation for adult patients with relapsed/refractory
multiple myeloma after three or more prior lines of therapies.
Poseida is currently enrolling patients in a Phase 1b portion of the clinical trial. The second
program, P-CD19CD20-ALLO1, is an allogeneic dual CAR-T candidate in
Phase 1 development for B-cell malignancies.
Dr. Yarema added, "Based on P-BCMA-ALLO1's promising
differentiated safety and efficacy results established with the
recent interim Phase 1 data presented at the IMS Annual
Meeting in September and in collaboration with Roche, we look
forward to continued patient enrollment in the Phase 1b trial. The new allogeneic dual CAR-T therapy
candidate announced today will leverage the same proprietary
Poseida GMP manufacturing platform that was used to create and
advance P-BCMA-ALLO1."
Poseida Cell Therapy R&D Day
The Company plans to
host its Cell Therapy R&D Day on November 14th, 2024, featuring
presentations from management and top scientists. The event will
highlight the Company's progress across its clinical-stage and
earlier-stage pipeline of differentiated allogeneic CAR-T therapies
in oncology and autoimmune disease.
The virtual event and access to the live webcast will be
available through the following registration link:
https://wsw.com/webcast/cc/pstx7/1467684. Registration for this
virtual event and access to a replay of the live webcast will also
be available on the Investors & Media section of
www.poseida.com. A replay of the webcast will be available for
approximately 90 days following the presentation.
Cash Position
As of June
30, 2024, the Company's cash, cash equivalents and
short-term investments balance was $237.8
million. With the $15 million
milestone from Roche's nomination of a new development candidate,
the Company expects that its cash, cash equivalents and short-term
investments together with other remaining near-term milestones and
other payments from Roche will be sufficient to fund operations
into early 2026. Potential additional anticipated progress and
payments under the Roche Collaboration Agreement and/or potential
additional business development could further extend the cash
runway.
