All healthy participants who received investigational mosaic-based vaccine regimen in Phase 1/2a APPROACH study showed HIV-1 immune responses at 52 weeks
In parallel study in non-human primates (NHPs), the same vaccine regimen afforded 67% protection against HIV-like virus
Mosaic-based vaccine regimen designed as ‘global vaccine’ to prevent wide variety of HIV subtypes responsible for worldwide pandemic
NEW BRUNSWICK, N.J., 6 July 2018 –Johnson & Johnson today announced that The Lancet has published key early-stage data regarding an investigational mosaic-based preventive vaccine regimen against HIV-1 infection that is in development at its Janssen Pharmaceutical Companies. In the Phase 1/2a APPROACH study, based on the data generated, the vaccine regimen was safe and well-tolerated and elicited a robust HIV antibody response in all healthy volunteers receiving active vaccine. Additionally, in a parallel study in non-human primates (NHPs), the most immunogenic mosaic-based vaccine regimen in humans demonstrated similar immune responses in NHPs and afforded 67% protection against an HIV-like virus.
The Lancet paper provides the first detailed analysis of topline results presented by Janssen at the 9th IAS Conference on HIV Science (IAS 2017) in July 2017, and supports the recent advancement of the mosaic-based vaccine regimen into its first large-scale efficacy study.
“These are promising but still early-stage results. At 52 weeks, we observed that the mosaic-based vaccine regimen induced robust and comparable immune responses to HIV in humans and in nonhuman primates, and the vaccine protected against infection with an HIV-like virus in nonhuman primates,” said Professor Dan Barouch, Harvard Medical School, Director of the Center for Virology and Vaccine Research at Beth Israel Deaconess Medical Center and a lead author of The Lancet paper.
Janssen’s investigational mosaic-based vaccine regimen contains immunogens created using genes from different viral subtypes responsible for HIV infections worldwide.
“The progress made in the last thirty years in the fight against HIV is remarkable, yet HIV still persists as a global health threat affecting millions,” said Paul Stoffels, M.D., Vice Chairman of the Executive Committee and Chief Scientific Officer, Johnson & Johnson. “The genetic diversity inherent in HIV brings many challenges, but we are committed to developing a ‘global vaccine’ effective against the multiple strains of the virus. Our quest is to develop a vaccine that would put an end to the worldwide pandemic for good.”
In addition to the results reported in The Lancet, the first long-term immunological data from the APPROACH study will be presented in an oral presentation at the 22nd International AIDS Conference (AIDS 2018) on Tuesday, July 24, 2018 in Amsterdam, The Netherlands.
Based on results from APPROACH and other early-stage studies, in November 2017 Janssen and its global partners initiated the first efficacy study for a mosaic-based vaccine regimen. The Phase 2b trial, HVTN 705/HPX2008 (also known as ‘Imbokodo’), aims to enroll 2,600 young women aged 18-35 in five sub-Saharan African countries to see whether the vaccine is safe and able to reduce HIV infection in this at-risk population. Participants are now enrolling at clinical research sites in South Africa, Zimbabwe and Malawi. The study has been cleared to start in Zambia, and regulatory approval is pending in Mozambique. Results from HVTN 705/ HPX2008 are expected in 2021.
“The HVTN 705/HPX2008 trial is built on a partnership with our global communities, Janssen and other stakeholders who are committed to finding an effective HIV vaccine. The imperative, if we are successful, is to then make sure that the effective HIV vaccine can be taken to scale and is accessible”, says Larry Corey, M.D., Principal Investigator of the HVTN, virologist and faculty member at Fred Hutchinson Cancer Research Center.
Although great progress has been made in the fight against HIV/AIDS, a safe and effective vaccine will likely be required to truly end the HIV pandemic. In 2016, nearly 37 million people were living with HIV globally, 1.8 million people were newly infected with HIV, and 1 million people died of AIDS.[i]
About the APPROACH and NHP Bridging Studies
APPROACH (HIV-V-A004/NCT02315703) is a Phase 1/2a study in 393 healthy HIV-uninfected adults in the U.S., Rwanda, Uganda, South Africa and Thailand. It is evaluating the safety, tolerability and immunogenicity of various mosaic-based vaccine regimens for HIV-1. These vaccine regimens contain two prime doses (weeks 0 and 12) of the mosaic viral vector Ad26.Mos.HIV, utilizing Janssen’s AdVac® technology based on adenovirus serotype 26 (Ad26), followed by two boosts (weeks 24 and 48) of either Ad26.Mos.HIV, MVA-Mosaic and/or different doses of the soluble protein Clade C gp140 adjuvanted with aluminum phosphate. By first priming and then boosting the immune system, the goal is to produce a strong and long-lasting immune response to HIV.
At 52 weeks, four weeks after the last vaccine dose, all vaccine regimens evaluated in APPROACH were safe and generally well-tolerated. Additionally, all regimens elicited robust humoral and cellular HIV-1 immune responses. The most immunogenic regimen in humans comprised mosaic Ad26 as the prime, and Ad26+gp140 as the boost. It elicited Env-specific binding antibody responses, antibody-dependent cellular phagocytosis responses, and T-cell responses in 100%, 80% and 83% of recipients, respectively. In a parallel bridging study in NHPs (n=72), the same Ad26/Ad26+gp140 vaccine regimen induced a similar magnitude, durability, and phenotype of immune responses, and afforded 67% protection against acquisition of infection with simian-human immunodeficiency virus (SHIV).
Janssen’s partners on the APPROACH study included Beth Israel Deaconess Medical Center (BIDMC), Harvard Medical School; the United States Military HIV Research Program (MHRP) at the Walter Reed Army Institute of Research (WRAIR), with the Henry M. Jackson Foundation for the Advancement of Military Medicine (HJF); the National Institute of Allergy and Infectious Diseases (NIAID), part of the US National Institutes of Health (NIH); the Ragon Institute of Massachusetts General Hospital, MIT and Harvard; the International AIDS Vaccine Initiative (IAVI); and the HIV Vaccine Trials Network (HVTN).
Since 2005, Janssen Vaccines & Prevention B.V. has been participating in the NIH-supported Integrated Preclinical/Clinical AIDS Vaccine Development (IPCAVD) program under grants AI066305, AI078526 and AI096040.
