Study of a Group B Streptococcus Vaccine in Pregnant Women Living With HIV and in Pregnant Women Who do Not Have HIV

Group B Streptococcal Infection Clinical Trial

Official title: A Multi-centre Study to Evaluate the Safety, Tolerability and Immunogenicity of Two Doses of a Group B Streptococcus Vaccine (GBS-NN/NN2) in Women Who Are Pregnant and Living With HIV and Women Who Are Pregnant and do Not Have HIV

Status Completed

Clinical Trial Summary

A randomised, placebo-controlled, double-blind study to evaluate the safety, tolerability and immunogenicity of the GBS-NN/NN2 (Recombinant protein vaccine against Group B Streptococcus) vaccine in women living with HIV and women without HIV,and their newborn babies from vaccination up to delivery/birth. Mothers and babies will be followed up for 6 months post-delivery.

Clinical Trial Description

100 women who are pregnant and living with HIV will randomly receive two 0.5 mL (millilitre) intramuscular injections of GBS-NN/NN2 vaccine (60 women) or placebo (15 women).

100 women who are pregnant and do not have HIV will randomly receive two 0.5 mL intramuscular injections of GBS-NN/NN2 vaccine (60 women) or placebo (15 women).

Participants will be screened at 24 to 28 weeks gestation (Days -14 to Day -1) and the groups will be dosed in parallel. The first dose of vaccine or placebo will be administered at Day 0 and the second dose will be administered 28±2 days later. Delivery is anticipated to be approximately 10 to 14 weeks after the first dose of vaccine.

For the analysis of the immune response, the placebo groups will be combined. For safety, the placebo groups will be analysed separately and will be combined for comparison with the potential vaccine groups. ;
