A Phase I Safty and Immunogenicity Study of SCT1000 in Healthy Women Aged 18 to 45 Years

September 14, 2021 updated by: Sinocelltech Ltd.

A Randomized, Double-Blind, Controlled (Positive and Placebo) Phase I Clinical Trial to Estimate Safty and Immunogenicity of the SCT1000 in Healthy Women Aged 18 to 45 Years

A phase 1 random, double blind, positive and placebo control trail was conducted in 120 healthy women in the arm A: 18-26 years old and Arm B: 27-45 years old. The 40 subjects to be inoculated with low, middle, and high dose vaccinefirst in sequence if there was no safety issue. In each dose group SCT1000 : placebo: positive =3:1:1.Two arms can be recruited at the same time. If the DSMB assessment shows that the adverse events of a certain dose group meet the criteria of suspension / termination, the dose group will be suspended / terminated, and the vaccination of this dose group or higher dose group will not be carried out, and the study of other dose groups will continue. If this happens at a low dose, the study will be suspended / terminated.

Study Overview

Detailed Description

Arm A: 18-26 years old. Random, double blind, Gardasil®9 positive control and placebo control was conducted in 120 healthy women in the arm. The first group was 40 subjects to be inoculated with low dose vaccine; After the first low dose group was completed, the safety observation was conducted 7 days after the first dose was completed. If there was no need to suspend / terminate the study, 40 subjects in the group were continued to receive the medium dose vaccine; After the first dose group was completed, the safety observation was 7 days after the first dose was completed. If there was no need to suspend / terminate the test, 40 subjects in the group were inoculated with high dose group. In each dose group SCT1000 : placebo: Gardasil® 9=3:1:1.Arm B: 27-45 years old. Random, double blind, Gardasil® positive control and placebo control was conducted in 120 healthy women in the arm. The first group was 40 subjects to be inoculated with low dose vaccine; After the first dose of the low dose group was completed, the safety observation was conducted 7 days after the first dose was completed. If there was no need to suspend / terminate the study, 40 subjects in the group were continued to be inoculated in the medium dose vaccine; After the first dose group was completed, the safety observation was 7 days after the first dose was completed. If there was no need to suspend / terminate the test, 40 subjects in the group were inoculated with high dose group. SCT1000 in each dose group: placebo: Gardasil® =3:1:1.Two arms can be recruited at the same time. If the DSMB assessment shows that the adverse events of a certain dose group meet the criteria of suspension / termination, the dose group will be suspended / terminated, and the vaccination of this dose group or higher dose group will not be carried out, and the study of other dose groups will continue. If this happens at a low dose, the study will be suspended / terminated.
