Fully non-viral approach to genetic medicine employs differentiated gene delivery, gene editing and gene insertion technology
Progressing two fully non-viral programs in rare disease with significant unmet patient need
Virtual R&D Day featuring academic experts and Poseida's leadership and scientific teams to be held today at 10:00am ET / 7:00am PT
"Poseida is forging ahead with a renewed focus on our genetic medicine portfolio. Our system of proprietary, non-viral tools used individually or together has the capacity to treat rare genetic diseases as well as address much more prevalent diseases," said Kristin Yarema, Ph.D., President & Chief Executive Officer of Poseida Therapeutics. "In the short-term, we are laser-focused on progressing our two lead non-viral candidates within areas of significant opportunity: P-KLKB1-101 for Hereditary Angioedema, and P-FVIII-101, which utilizes our fully non-viral stable gene insertion technique to treat Hemophilia A, a condition affecting approximately 30,000 adults and children in the
"Poseida has developed a broad suite of fully non-viral, differentiated genetic engineering technologies, including stable, potentially site-specific insertion of whole genes, high-fidelity gene editing, and strength in delivery systems including lipid nanoparticles," said Blair Madison, Ph.D., Chief Scientific Officer of Gene Therapy at Poseida Therapeutics. "We believe this uniquely positions us in the industry to deliver on the hope and promise of genetic medicines and bring much-needed therapies to patients in need."
The event will highlight the Company's proprietary genetic engineering and delivery platform, including its non-viral gene insertion and gene editing programs. External expert speakers will include:
- Marc Riedl, M.D., M.S., Professor of Medicine and Clinical Director of the
U.S. HAEA Angioedema Center at University ofCalifornia ,San Diego ; and - Steven W. Pipe, M.D., Professor of Pediatrics and Pathology, University of
Michigan
Key Gene Therapy R&D Day Topics and Highlights
Gene Therapy Programs
The Company will present advancements in fully non-viral liver-directed gene therapies highlighting the potential for functional cures across commercially viable indications.
- P-KLKB1-101 is the Company's lead liver-directed investigational gene therapy program for the treatment of hereditary angioedema (HAE), a rare, inherited disorder which results in the swelling of the limbs, intestinal tract, and airways which can be both debilitating and life-threatening. The Company will share data highlighting durable disease correction and high fidelity in pre-clinical studies using the Company's enhanced editing technology, Cas-CLOVERTM.
- P-FVIII-101, the Company's second non-viral gene therapy program, is a liver-directed investigational in vivo gene therapy for the treatment of Hemophilia A, a hereditary disorder caused by a deficiency in Factor VIII (FVIII) production resulting in excessive bleeding occurring either spontaneously or due to trauma. The Company will share data demonstrating durability and restoration of FVIII deficiency to near-normal levels in adult mouse models.
Technology Innovation in Gene Therapy
The Company will highlight significant advancements in its emerging platform technologies.
- Site-specific Super piggyBac® is a single enzyme fusion system for site-specific integration, executing clean DNA gene insertion without double strand breaks, unintended mutations, or the need for DNA repair. The Company will announce that the current molecular evolution of its platform yields a 30-fold improvement of DNA expression and efficient targeted cargo integration at single- and multi-copy sites. These data support the potential for the Company's non-viral insertion technology as an efficient and safe approach to achieve sustained DNA integration and expression to remediate disease.
- Cas-CLOVER is a proprietary high-fidelity nuclease for enabling clean site-specific gene editing that is engineered for high specificity. The Company will present data confirming and validating the benefits and advantages of Cas-CLOVER in multiple applications and disease areas.
- Novel Lipids and DNA Delivery: The Company is leveraging proprietary lipids notable for their low immunogenicity, dose titration potential, and ability to be manufactured at scale and favorable cost. The Company has achieved multiple breakthroughs in its delivery technology, including novel lipids for in vivo delivery of its technology as well as innovations enabling improved in vivo non-viral DNA delivery.
