Study Endpoints

Primary Endpoints

Percentage of Participants With at Least One Treatment-Emergent Adverse Events (TEAEs) and Serious TEAEs
From first dose of study drug through 30 days following the last dose (approximately up to Week 13)

An adverse event (AE) was defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. SAEs were any untoward medical occurrence that at any dose: resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, resulted in congenital anomaly or birth defect, or was considered an important medical event. TEAEs were defined for this trial as any AEs that occurred following Day 0 following administration of study drug (IM + EP), until 30 days following the last dose. TEAEs included both serious and non-serious TEAEs.

Secondary Endpoints

Change in Number of Recurrent Respiratory Papillomatosis (RRP) Surgical Interventions in One Year Following Day 0, Compared to One Year Prior to Day 0
Up to Week 52
Percentage of Participants by Percent Reduction in RRP Surgical Interventions Post Baseline Compared to Prior Year
Up to Week 52
