Detailed Description
The main objective is to explore the immunogenicity of HPV therapeutic DNA vaccine NWRD08.The secondary objective was to observe the safety of NWRD08 in cervical patients who were positive for HPV16 and/or HPV18, and to initially explore the efficacy of NWRD08.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: lose dose,high dose Four dose groups were set up: dose group 1, a single dose of 2mg, administered at week 0, 4 and 12, three times in total; Dose group 2, a single dose of 6mg, respectively at the 0, 4, 12 weeks, a total of 3 times; Dose group 3, a single dose of 2mg, was given at the 0, 2, 4, 12 weeks, a total of 4 times; Dose group 4, with a single dose of 6mg, was given 4 times at week 0, 2, 4 and 12, respectively. There were 3 subjects in each group. Climb from the low dose group to the high dose group. |
Biological: NWRD08
Subjects in dose group 1 and 2 were intramuscularly injected with NWRD08 at week 0, week 4 and week 12 by electric pulse gene delivery instrument, respectively. Subjects in dose group 3 and 4 were intramuscularly injected NWRD08 at week 0, week 2, week 4 and week 12 by electric pulse gene delivery instrument, respectively.

Outcome Measures
Primary Outcome Measures
- HPV 16/18 E6E7 specific immune response in peripheral blood after vaccination compared to before vaccination. [Week36]
Analysis of immunogenicity data included the level, type, subtype, and time and duration of specific humoral and cellular immune responses in peripheral blood before and after vaccination.
Secondary Outcome Measures
- Adverse Events (AEs) [End of study]
Adverse Events (AEs), adverse events according to type, frequency, severity [according to the Classification Scale of Adverse Events in Clinical Trials for Preventive Vaccines issued by the Center for Drug Evaluation (CDE) of the National Medical Products Administration in 2019], occurrence time, and severity. And whether it's related to treatment.
- proportion of patients with HPV virus clearance [Week 36]
Proportion of patients with negative HPV16/18 DNA and E6E7 mRNA.
- proportion of patients with regression of cervical lesions [Week 36]
HSIL patients 36 weeks group / 18 DNA and E6E7 mRNA overcast and histological ratio dropped below CIN1 and patients; HSIL patients 36 weeks group / 18 DNA and E6E7 mRNA overcast and histological the proportion of patients with squamous intraepithelial lesions; LSIL patients 18 DNA and 36 weeks group/E6E7 mRNA overcast and cytology squamous intraepithelial lesions;
