Precigen PGEN, a commercial-stage company specializing in innovative precision medicines, is making steady progress with strong commercial performance from its sole marketed drug Papzimeos (zopapogene imadenovec-drba). As the first and only FDA-approved therapy for adults with recurrent respiratory papillomatosis (RRP), Papzimeos provides Precigen with a differentiated commercial position and a potentially durable revenue base.
Year to date, PGEN shares have surged 71.3% compared with the industry’s 7.1% growth.

Papzimeos Is Driving Rapid Revenue Growth
Papzimeos has demonstrated strong early commercial momentum since its launch in August 2025. In the second quarter of 2026, the company recorded product revenues of $53.3 million, more than doubling sequentially. For the first six months of 2026, the product generated $75.1 million of revenues.
Notably, the rapid revenue ramp translated into quarterly profitability, with Precigen reporting $20.1 million in net income in the second quarter compared with a $26.6 million net loss in the year-ago quarter. Rising patient hub enrollment and expanding adoption across major medical centers and community practices indicate that the product is gaining traction beyond the initial launch phase.
Market Exclusivity Provides Revenue Protection for PGEN
Papzimeos benefits from seven years of FDA market exclusivity through Aug. 14, 2032. Combined with its first-in-class position and lack of an approved competing therapy for adult RRP, this protection gives Precigen an opportunity to establish a durable commercial franchise before potential competitors enter the market.
International Expansion Adds Long-Term Upside for PGEN
Precigen is pursuing additional growth opportunities outside the United States. The company’s marketing authorization application submitted to the European Medicines Agency in November 2025 is currently under review. Approval in Europe could provide another source of revenue growth. A redosing study is also underway, which could expand the product’s long-term treatment opportunity if supported by clinical results.
PRGN-2009 Provides Pipeline Optionality for PGEN
Beyond Papzimeos, Precigen retains pipeline potential through its AdenoVerse platform. PRGN-2009 is an investigational AdenoVerse immunotherapy being developed to activate the immune system and target HPV-associated cancers. The candidate is currently being evaluated in phase II clinical studies in patients with newly diagnosed HPV-associated oropharyngeal cancer. In parallel, Precigen is conducting a multicenter phase II study evaluating PRGN-2009 in combination with Merck & Co’s MRK Keytruda (pembrolizumab) in patients with recurrent or metastatic cervical cancer. Keytruda, MRK’s blockbuster drug, is approved for several types of cancers globally.
Although the candidate remains at the clinical stage and carries development risk, its progress could provide an additional source of long-term value and further validate Precigen’s HPV-focused technology. The company plans to provide an update on the broader AdenoVerse portfolio, including PRGN-2009, by the end of 2026.
