The FDA recently approved Papzimeos (zopapogene imadenovec-drba), a new therapy from Precigen Inc., for the treatment of adults with recurrent respiratory papillomatosis (RRP). This marks the first and only approved therapy available for the rare condition.
RRP is a debilitating and sometimes life-threatening disease caused by chronic infection with HPV types 6 or 11. The infection leads to recurrent benign tumors, or papillomas, within the respiratory tract. While typically noncancerous, papillomas consist of abnormal epithelial cell growths that can obstruct airways and require repeated surgical interventions.
RRP affects an estimated 27,000 adults in the United States, highlighting the unmet need for effective treatment options. Until now, patients have relied primarily on repeated surgical procedures to manage symptoms.
According to Precigen, Papzimeos published a defined dosing schedule: patients receive treatment on day one, followed by another dose at week two, and then once every four weeks thereafter. The therapy is supplied as a frozen suspension for subcutaneous injection. Prescribing information states that the therapy be rapidly thawed and immediately administered. Given the complexity of the disease, need for close monitoring, and preparation & handling, administration will take place in a specialist’s office.
Precigen has announced a list price of $115,000 per vial, totaling approximately $460,000 for the first twelve-week course of treatment.
Distribution and logistics details have not yet been disclosed.
