GERMANTOWN, Md., Sept. 21, 2026 /PRNewswire/ -- Precigen, Inc. (Nasdaq: PGEN), a commercial-stage biopharmaceutical company specializing in the advancement of innovative precision medicines to improve the lives of patients, today announced that the United States Food and Drug Administration (FDA) granted platform technology designation to the AdenoVerse® immunotherapeutic platform, which is used in the company's first commercial product, PAPZIMEOS®. The designation reflects the adaptability and potential of the platform to address a broad range of indications, including HPV-positive malignancies such as head and neck, cervical, anal, vulvar and vaginal cancers, as well as other diseases that may be targeted by future AdenoVerse-based product candidates.
FDA platform technology designation creates a pathway to leverage data generated for the development of PAPZIMEOS to potentially accelerate development of future AdenoVerse programs by utilizing existing manufacturing and preclinical knowledge to support future marketing applications and reduce duplication of development work. Platform technology designation provides opportunities for early FDA engagement, the ability to receive timely advice by having additional engagement with the FDA during development, and consideration of prior FDA manufacturing inspections for future applications.
To qualify for the platform technology designation, a platform must already be used in an FDA-approved product and the available evidence must demonstrate that it is well characterized, reproducible and has the potential to be adaptable across multiple products without compromising quality, manufacturing or safety. In granting this designation, the FDA determined that the AdenoVerse platform can be applied consistently across multiple products and is reasonably likely to generate meaningful efficiencies to the development or manufacturing process, and to the regulatory review process.
"This designation has the potential to accelerate the development of Precigen's broader AdenoVerse portfolio by allowing us to build on the technology established through PAPZIMEOS, which was approved by the FDA in August 2025. We expect the near-term impact will be especially meaningful for PRGN-2009 across multiple HPV-associated cancers, including cervical cancer and oropharyngeal squamous cell carcinoma. Importantly, the potential extends beyond PRGN-2009 to future AdenoVerse candidates such as those targeting additional cancers and other diseases," said Helen Sabzevari, PhD, President and CEO of Precigen. "We thank the FDA for recognizing the potential of the AdenoVerse platform. This designation will enable us to leverage prior data and engage with the FDA earlier and more frequently, creating opportunities to reduce duplicative work and bring greater speed, efficiency and predictability to the development of future AdenoVerse therapies."
AdenoVerse® Clinical Portfolio
Precigen's AdenoVerse portfolio includes a Phase 2 study of PRGN-2009 in combination with pembrolizumab in newly diagnosed patients with HPV-associated oropharyngeal squamous cell carcinoma (NCT05996523) and a Phase 2 study of PRGN-2009 in combination with pembrolizumab in patients with recurrent or metastatic cervical cancer (NCT06157151). The portfolio also includes PAPZIMEOS® (zopapogene imadenovec-drba; formerly PRGN-2012), which is the first FDA-approved therapy for the treatment of adults with recurrent respiratory papillomatosis (RRP). An open-label study evaluating the efficacy of redosing PAPZIMEOS in adults with RRP is currently enrolling (NCT06538480).
