This is a single-arm, open label, multi-center clinical study to evaluate the safety, tolerability and immunogenicity HPV16 targeted mRNA therapeutic vaccine (NWRD09) in HPV16 related cervical high-grade squamous intraepithelial lesions (HSlL).
This study is divided into three dose groups. Each patient will be administered NWRD09 by intramuscular injection at week 0,2,4 and12. The Maximum Tolerated Dose of NWRD09 will be determined by the classical 3+3 dose escalation schedule. The number of patients will be ranged from 9 to 18. The subjects shall continue to receive safety follow-up until 28 days after the third administration. Colposcopy and biopsy were performed at week 24. This study will select 1-2 dose levels for subject expansion based on the dose escalation phase, to further evaluate the safety, tolerability, immunogenicity, and efficacy of NWRD09 in HPV16 related cervical HSIL patients.

RECRUITINGSafety
All adverse events (AE) will be determined based on the rate and severity grade of events, including incidence and severity of serious adverse events (SAE) (according to NCI-CTCAE Standard version 5.0 of common Terms for Adverse Events).
Time frame: To week 24
Dose-limiting toxicity (DLT)
It would be determined based on the rate and severity grade of events or abnormalities through evaluating systemic or local adverse events, clinical laboratory test results, vital signs that is definitely, probably, or possibly related to the test drug occurring within 28 days of the third dosing will be classified as DLT during dosing climb.
Time frame: Within 28 days of the third dosing
Immunogenicity
Immunologic reactogenicity by measuring HPV16 specific T cell response (IFN-γ ELISPOT) and anti HPV16 antibodies (ELISA) in blood samples
Time frame: Week 4、8、16、24、48
Histopathology outcome and HPV Viral clearance
Number of subjects with virologically-proven clearance of HPV 16 and number of subjects with histopathological regression of cervical lesions to CIN 1 or normal
Time frame: Week 24.
The recommended phase II dose (RP2D)
The recommended phase II dose (RP2D) was selected on the basis of tolerability during the safety expansion.
Time frame: Week 24
