Safety and Effects of Using Prime-boost HIVIS DNA and MVA-CMDR Vaccine Regimens With or Without Toll-like Receptor 4 Agonist on HIV Reservoirs in Perinatally HIV Infected Children and Youth (HVRRICANE)

Phase I, Proof of Concept, Open-Label, Randomized Clinical Trial to Evaluate the Safety and Effects of Using Prime-boost HIVIS DNA and MVA-CMDR Vaccine Regimens With or Without Toll-like Receptor 4 Agonist on HIV Reservoirs in Perinatally HIV Infected Children and Youth

Phase I, Proof of Concept, Open-Label, Randomized Clinical Trial to Evaluate the Safety and Effects of Using Prime-boost HIVIS DNA and MVA-CMDR Vaccine Regimens with or without Toll-like Receptor 4 Agonist on HIV Reservoirs in Perinatally HIV Infected Children and Youth

Study Overview

Detailed Description

HIVIS DNA and MVA-CMDR vaccines induce immune responses important for clearing infected cells: broad HIV-specific CD8+ cytotoxic T cells, potent antibodydependent cellular cytotoxicity (ADCC), and binding antibody (Ab) and neutralizing antibody (NAb). The study include early treated children because of their healthy immunity and small HIV reservoirs. Giving licensed vaccine, Cervarix®, against human papilloma virus (HPV) that contains toll-like receptor (TLR) 4 agonist with HIVIS DNA could increase DNA antigen loading on dendritic cells and promote adaptive immune responses to the HIV vaccine.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Arm 1 (n=10): HIVIS DNA / MVA-CMDR

Arm 1 (n=10) will receive 1500 micrograms (0.5ml) HIVIS DNA IM by needle-free injection at weeks 0 and 4 followed by intramuscular (IM) needle injection of 1 X 108 IU/mL (1ml) MVA-CMDR at weeks 24 and 36 in the same arm as HIVIS DNA.

Participants who have been randomized to receive HIVIS DNA and MVA-CMDR alone (ARM 1) will be administered Cervarix after week 72, the last study follow-up visit, if required.

HIVIS DNA IM by needle-free injection at weeks 0 and 4 followed by intramuscular (IM) needle injection of 1 X 108 IU/mL (1ml) MVA-CMDR at weeks 24 and 36 in the same arm as HIVIS DNA.
Experimental: Arm 2 (n=10): HIVIS DNA + Cervarix/ / MVA-CMDR
Arm 2 (n=10) will receive 0.5 ml of Cervarix IM by needle injection followed by 1500 micrograms (0.5ml) per injection of HIVIS DNA IM by a needle-free injection device in the skin above (proximal to) the Cervarix injection (within 1.5 cm). They will receive 1 X 108 IU/mL (1ml) MVA-CMDR IM by needle injection at weeks 24 and 36 in the same arm as HIVIS DNA. They will also receive 0.5 ml Cervarix at the time of the first MVACMDR injection in the opposite arm from the MVA injection at week 24.
