PG - 100731 LID - 10.1016/j.lanwpc.2023.100731 [doi] LID - 100731 AB - BACKGROUND: A safe and highly efficacious Escherichia coli (E. coli)-produced HPV 16/18 bivalent vaccine has been prequalified by the World Health Organization. Here, we conducted a single-center, open-label, dose-escalation phase 1 clinical trial to evaluate the safety and immunogenicity of the second-generation nonavalent HPV 6/11/16/18/31/33/45/52/58 vaccine. METHOD: Twenty-four eligible volunteers aged 18-45 years were enrolled in January 2019 in Dongtai, China and received 0.5 mL (135 mug) or 1.0 mL (270 mug) of the candidate vaccine with a 0/1/6-month dose-escalation schedule. Local and systemic adverse events (AEs) occurring within 30 days after each vaccination and serious adverse events (SAEs) occurring within 7 months were recorded. Blood samples from each participant were collected before and 2 days after the first and third vaccinations to determine changes in laboratory parameters. Serum IgG and neutralizing antibody (nAb) levels against each HPV type at month 7 were analyzed (ClinicalTrials.gov: NCT03813940). FINDINGS: The incidences of total AEs in the 135 mug and 270 mug groups were 66.7% and 83.3%, respectively. All AEs were mild or moderate, and no SAEs were reported. No clinically significant changes were found in paired blood indices before or after any of the vaccinations. All the participants in the per-protocol set except for two who failed to seroconvert for HPV 11 or 58 in the 135 mug group seroconverted at month 7 for both IgG and nAbs. INTERPRETATION: The candidate E. coli-produced 9vHPV vaccine has been preliminarily proven to be well tolerated and immunogenic, which encourages further studies in large cohorts with a wider age range.
