Collaboration to leverage Poseida’s non-viral piggyBac® DNA Modification System, Cas-CLOVER™ Site-Specific Gene Editing System, biodegradable DNA and RNA nanoparticle delivery technology and other proprietary genetic engineering platforms

Collaboration to initially include up to six liver- and hematopoietic stem cell (HSC)- directed indications with an option to add two additional programs

In addition to an upfront payment, Poseida is eligible to receive preclinical, development and commercial milestone payments plus tiered royalties into the double digits

SAN DIEGO, CA, USA I October 12, 2021 I 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 that it has entered into a research collaboration and exclusive license agreement with Takeda Pharmaceutical Company Limited (“Takeda”) to utilize Poseida’s piggyBac, Cas-CLOVER, biodegradable DNA and RNA nanoparticle delivery technology and other 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.

“We are excited to partner with Takeda, a global biopharmaceutical leader whose commitment to the development of novel therapies for rare diseases complements our innovative platform technologies and robust gene therapy pipeline,” said Eric Ostertag, M.D., Ph.D., Chief Executive Officer of Poseida. “Our technologies offer highly efficient gene delivery, fully integrated non-viral genome insertion and ultra-precise site-specific gene editing. Together with Takeda, we look forward to developing potential cures for a number of genetic diseases with high unmet need.”

Under the terms of the agreement, the parties will collaborate to initially develop up to six in vivo gene therapy programs utilizing Poseida’s novel technology platforms including piggyBac, Cas-CLOVER and biodegradable nanoparticle technology, as well as certain emerging technologies.  Takeda also has an option to add two additional programs to the collaboration and is obligated to provide funding for all collaboration program R&D costs.

Poseida will receive an upfront payment of $45 million and preclinical milestones that together could potentially exceed $125 million in the aggregate, if milestones for six programs are achieved. Poseida is also eligible to receive future clinical development, regulatory, and commercial milestone payments with a total potential value over the course of the partnership of up to $2.7 billion if milestones for all six programs are achieved, and up to $3.6 billion if the milestones related to the two optional programs are also achieved. Poseida will lead research activities up to candidate selection, after which Takeda will assume responsibility for further development and commercialization.

“Poseida’s differentiated platform technologies show great promise in developing non-viral in vivo gene therapies using their novel genetic engineering and delivery technologies that complement our existing collaborations,” said Takeda Rare Diseases Drug Discovery Unit Head, Madhu Natarajan. “This partnership reinforces Takeda’s commitment to investing in next-generation gene therapy approaches that have the potential to deliver functional cures to patients with rare genetic and hematologic diseases. We look forward to partnering with Poseida where we can apply our broad development capabilities to help progress several early stage preclinical programs.”
