Recommended Supplies and Materials
Receipt of PAPZIMEOS
PAPZIMEOS is provided as a sterile, frozen suspension that has been aseptically filled into single-dose vials fitted with a rubber stopper and aluminum flip-cap seal. Each vial is sealed inside a pouch, which is placed in the carton along with a Package Insert. The PAPZIMEOS carton is shipped frozen at ≤ -60°C [≤ -76°F] in an insulated shipping box containing dry ice. On receipt, the PAPZIMEOS carton must be stored in a freezer at ≤ -60°C [≤ -76°F].
Preparation of PAPZIMEOS for Injection
DO NOT hold PAPZIMEOS at room temperature for more than 60 minutes after thawing.
DO NOT store thawed PAPZIMEOS vials or filled syringes in a refrigerator, freezer, or on dry ice.
Treat any PAPZIMEOS spills with a virucidal agent (such as sodium hypochlorite with 0.5% active chlorine or 6% hydrogen peroxide) for 15 minutes. Dispose of any unused product or waste materials as per facility biohazard waste disposal procedure.
Administer PAPZIMEOS via subcutaneous injection with the following procedures:
PAPZIMEOS is supplied as a slightly opalescent to opalescent, colorless suspension for subcutaneous injection with a concentration of 5×1011 PU/mL. Each single-dose vial delivers a minimum extractable volume of 1 mL [see How Supplied/Storage and Handling (16)].
Injection-site reactions have occurred with PAPZIMEOS injection. Monitor patients for local site reactions for at least 30 minutes after the initial treatment and manage accordingly.
Thrombotic events may occur following administration of adenoviral vector-based therapies including PAPZIMEOS due to the potential to induce prothrombotic antibody development. Monitor patients for signs and symptoms of thrombotic events and treat events according to clinical practice.
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The safety data described in this section reflects exposure to PAPZIMEOS in one clinical study (Study PRGN-2012-201). A total of 38 adults with recurrent respiratory papillomatosis received a PAPZIMEOS dose of either 1×1011 PU (n=3), or 5×1011 PU (n=35) per injection on Days 1, 15, 43, and 85 [see Clinical Studies (14)]. The most common adverse reactions (incidence ≥5%) are summarized in Table 2.

Risk Summary
There are no available data with PAPZIMEOS in pregnant women. Animal reproductive and developmental toxicity studies have not been conducted with PAPZIMEOS. In the PRGN-2012-201 study, one patient reported pregnancy at 6 months following completion of treatment with PAPZIMEOS. The patient delivered at 40 weeks without any reported birth complications or neonatal concerns.
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
Risk Summary
There is no information available on the presence of PAPZIMEOS in human milk, the effects on the breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for PAPZIMEOS and any potential adverse effects on the breastfed child from PAPZIMEOS or from the underlying maternal condition.
The safety and effectiveness of PAPZIMEOS have not been established in pediatric patients.
There were 9 patients (24%) 65 years of age and older and 1 patient (3%) 75 years of age and older in Study PRGN-2012-201. Clinical studies of PAPZIMEOS did not include sufficient numbers of patients 65 years of age and older to determine whether they respond differently from younger patients.
PAPZIMEOS (zopapogene imadenovec-drba) is a non-replicating adenoviral vector-based immunotherapy designed to express a fusion antigen comprising selected regions of human papillomavirus (HPV) types 6 and 11 proteins.
PAPZIMEOS has a concentration of 5×1011 PU/mL. Each single-dose vial contains a minimum extractable volume of 1 mL and the following excipients: Tris base (10 mM), sodium chloride (75 mM), magnesium chloride hexahydrate (1 mM), polysorbate 80 (0.019 mM), and trehalose dihydrate (146 mM).
PAPZIMEOS is a sterile, slightly opalescent to opalescent colorless suspension.
The product contains no preservatives.
PAPZIMEOS is a non-replicating adenoviral vector-based immunotherapy designed to express a fusion antigen of selected regions of human papillomavirus (HPV) proteins expressed in HPV 6- and HPV 11-infected cells. PAPZIMEOS is designed to generate an immune response directed against HPV 6 and HPV 11 proteins in patients with recurrent respiratory papillomatosis.
The pharmacodynamic effect of PAPZIMEOS was evaluated in Study PRGN-2012-201 [see Clinical Studies (14)]. In 28 patients evaluated at completion of treatment, the induction of HPV 6- and HPV 11-specific T cell responses in RRP patients, was higher in RRP patients demonstrating a clinical response to treatment, i.e. reduction in or elimination of the requirement for surgical debulking during the 12 months following completion of treatment, with mean fold-change from baseline of 164.9 versus 5.1 (p<0.018). This difference persisted at 12 weeks post-treatment, with mean fold-change of 61.5 in responders versus 11.5 in non-responders.
The efficacy of PAPZIMEOS was evaluated in an open-label, single-arm study in adults with recurrent respiratory papillomatosis (PRGN-2012-201; NCT04724980). The study enrolled adults who had histological and clinically diagnosed recurrent respiratory papillomatosis and had 3 or more debulking procedures to remove laryngotracheal papillomas in the 12 months prior to treatment with PAPZIMEOS.
A total of 38 patients received subcutaneous injections of PAPZIMEOS on days 1, 15, 43, and 85. Prior to initiation of treatment with PAPZIMEOS (Day 1), patients underwent a standard-of-care surgical debulking procedure to remove laryngotracheal papillomas. Physicians also had the option to remove any visible papillomas during the treatment interval. Of the 38 patients, 3 patients were treated with PAPZIMEOS at a dose of 1×1011 particle units (PU) per injection. Thirty-five patients were treated at a dose of 5×1011 PU per injection and were included in the efficacy evaluation.
The demographic characteristics of the population were as follows: the median age was 50 years (range 20 to 88 years), 15 patients (39%) were female, 33 patients (87%) were White, 1 patient (3%) was Asian, 1 patient (3%) was African American, 1 patient (3%) was of “other” race, 2 patients (5%) were of unknown race, and 32 patients (84%) were non-Hispanic or Latino. The mean (SD) BMI was 28 (6) kg/m2. The median number of baseline surgical procedures performed in the 12 months prior to treatment was 4 (range 3 to 10). This included the protocol mandated debulking surgery on Day 1 to establish minimal residual disease.
The primary efficacy endpoint was the percentage of patients with a complete response to PAPZIMEOS treatment, defined as no requirement for surgical intervention in the 12 months after treatment.
At a dose of 5×1011 PU per injection, 18 out of 35 patients achieved a complete response at 12 months resulting in a complete response rate of 51% [95% confidence interval (CI) 34 to 69%]. Of the 18 patients with a complete response in the ongoing study, 15 demonstrated continued complete response at 24 months yielding a complete response rate of 43% (95% CI 26 to 61%) at 2 years for the 35 patients in the efficacy population.
At a dose of 1×1011 PU per injection, no patient (0 out of 3) achieved a complete response.
