PGEN’s PAPZIMEOS Approval Drives Early Adoption as New RRP Therapy Gains Ground

Rapid FDA Approval of PAPZIMEOS Spurs Uptake in Underserved RRP Market

Precigen (NASDAQ:PGEN) is seeing early commercial momentum after the FDA granted full approval for PAPZIMEOS in August 2025—the first and only therapy approved for adults with recurrent respiratory papillomatosis (RRP). With a broad label, PAPZIMEOS marks a milestone for a rare disease that, until now, has only been managed through repeated surgeries.

Within months of approval, PAPZIMEOS is shipping nationwide. More than 100 adult RRP patients have already been enrolled in the PAPZIMEOS Patient Hub, with additional patient identification surging via major institutions. Over 90% of target institutions have engaged with Precigen’s newly deployed sales team, reflecting substantial prescriber and institutional interest in this newly available therapy.

Clinical Results Show Durable Responses—Reducing Surgeries for RRP Patients

Pivotal trial data revealed ongoing, durable complete responses among treated patients. Notably, 83% of complete responders showed sustained remission at a median of 36 months without additional interventions. Rates of reduced surgical burden were also impressive, with the need for surgery falling in 86% of patients in year one, 91% in year two, and 95% by year three. Importantly, no new safety events emerged in long-term follow-up, bolstering confidence in the drug’s risk profile.

Payer Coverage and Market Access Accelerate Launch Success

PAPZIMEOS quickly achieved significant market access, with over 100 million privately insured lives now covered, alongside Medicare and Medicaid inclusion. Such swift payer adoption highlights both the clinical demand and anticipated impact of PAPZIMEOS on healthcare systems managing RRP’s burdensome cycle of repeat interventions and high resource utilization.

Financials: Higher Non-Cash Expenses, but Cash Runway to Break-Even

Despite the early revenue uptick from PAPZIMEOS and increased licensing revenues, Q3 net loss deepened to $325.34 million, largely due to non-cash charges—especially a one-time $179 million deemed dividend and a $111.5 million fair value adjustment to warrant liabilities. Operational expenses rose, driven by launch-related investments and R&D. On the bright side, Precigen’s $123.6 million in cash and investments, coupled with a $100 million credit facility tranche received in September, is expected to support operations through the critical commercialization phase until break-even.

Market Outlook: First-Mover Advantage in a High-Need Segment

With around 27,000 adults in the US affected by RRP and no alternative therapies available, PAPZIMEOS is positioned as the new standard of care. Beyond early patient uptake and durable clinical data, payer access and broad label approval provide a platform for expansion—including a recent European submission to the EMA.

Key Takeaway: Precigen’s Strong Launch Momentum Balances Heavy Investment

Precigen’s aggressive push into the RRP space is underpinned by breakthrough clinical results and robust early demand. While near-term losses reflect substantial investment and accounting charges rather than core operational trends, the launch trajectory, strong payer access, and a healthy cash runway all underscore the strategic value of PAPZIMEOS in a field desperate for innovation.

As commercialization efforts continue, investors and industry observers may want to monitor PAPZIMEOS’s market adoption rates, insurance coverage progression, and updates on EU regulatory outcomes—each of which could further transform Precigen’s growth profile over the coming quarters.
