Официальное название

Randomised, Double-blind, Placebo-controlled Phase 1 Dose-escalation Study of FluBHPVE6E7 in HPV16-infected Women with NILM, ASC-US, LSIL or Low-grade CIN

Обзор

BS-02 is a randomised, double-blind, placebo-controlled, phase 1 dose escalation study to assess the safety, tolerability and immunogenicity of FluBHPVE6E7, in women infected with HPV-16. with cervical cytological evaluation negative for intraepithelial lesion or malignancy (NILM), atypical squamous cells of undetermined significance (ASC-US), low grade squamous intraepithelial lesion (LSIL), or low-grade cervical intraepithelial neoplasia (CIN1).

Подробное описание

FluBHPVE6E7 is an influenza virus vector that was modified on several levels to be used as an immunotherapeutic agent against human papillomavirus (HPV) infections, and precancers and cancers induced by HPV.

Study BS-02 investigates the safety, tolerability and immunogenicity of FluBHPVE6E7 in HPV-16 infected women.

FluBHPVE6E7 is administered three times at two dose levels. The first dose is administered into the cervix, subsequent doses are administered intramuscularly.

  Intracervical administration for first dose followed by intramuscular administration for subsequent doses at recommended dose level and determined schedule
• Препарат Placebo
