A significant step for developing our PD-1-Enhanced DNA Vaccine against HIV/AIDS
HONG KONG, Feb. 16, 2023 /PRNewswire/ -- Immuno Cure BioTech, a clinical stage biotechnology group based in the Hong Kong Science Park specialising in PD-1-Enhanced DNA vaccines and immunotherapies, announced the kicking off of the Phase I Clinical Trial of ICVAX, a therapeutic vaccine against HIV/AIDS, at The National Clinical Research Center for Infectious Diseases at The Third People's Hospital of Shenzhen.
HIV-1 is the causative agent of AIDS. To date, HIV-1 continues to spread, leading to over 38 million people living with the virus and over 40 million deaths worldwide by 2021. Since the life-long antiretroviral treatment ("ART") neither cures HIV/AIDS nor fully restores immune function, it is critical to discover an effective immunotherapy of potentiating host immunity to achieve a functional cure, a state of suppressed viremia below detection limit for a prolonged period in HIV-infected patients without receiving ART. Scientists at HKU-AIDS Institute have invented the PD-1-Enhanced DNA vaccine platform, which has been exclusively licensed to Immuno Cure on a worldwide basis. The innovation of this platform is based on soluble PD-1-linked antigen targeting to dendritic cells for inducing enhanced host immune responses especially CD8+ T-cells, which is the major immune surveillance force for eliminating HIV-1 infected cells. ICVAX is developed by Immuno Cure in collaboration with HKU-AIDS Institute, aiming to induce broadly reactive polyfunctional viral-specific T cells to achieve functional cure in HIV/AIDS.
The trial is designed as a randomized, double-blinded, placebo-controlled, dose-escalation study to evaluate the safety and immunogenicity of ICVAX in stable HIV/AIDS patients under antiretroviral therapy. By the end of the study, an optimal vaccine regimen that is both safe and immunogenic in stable HIV patients will be identified for subsequent clinical trials in the future.
Immuno Cure has been granted ΗΚ$8 million funding for this clinical trial under the Clinical Translational Catalyst Program ("CTC Program") of the Institute for Translational Research ("ITR") of the Hong Kong Science Park.
In addition to ICVAX, Immuno Cure currently has another PD-1-Enhanced DNA vaccine, called ICCOV, in preparation for advancement to Phase 2 clinical trial for the fight against COVID-19.
Dr JIN Xia, CEO of Immuno Cure said, "Initiation of this phase 1 clinical trial is supported by promising preclinical study results and safety evaluation that demonstrated the antiviral activity of this first-in-class therapeutic vaccine designed and developed specifically against HIV. We are extremely impressed by the professionalism of the National Clinical Research Center at The Third People's Hospital of Shenzhen. I am optimistic in the outcome of this trial and eager to proceed to the next phase soon."
Professor CHEN Zhiwei, Director of AIDS Institute at the University of Hong Kong and the Principal Scientific Advisor of Immuno Cure said, "HIV has been a major public health challenge for more than four decades. With support from Theme-based Research Scheme, our vaccine platform has demonstrated safety and potent efficacy in non-human primates. I am excited to kick off this clinical trial, which will benefit patients immediately and help us assess whether the excellent preclinical data can be translated into human, laying solid foundation for vaccine development towards HIV-1 functional cure."
Dr Percy CHENG, Chairman of Immuno Cure concludes, "We are privileged to be partnering with HKU-AIDS Institute and ITR of the Hong Kong Science Park and grateful for the CTC Program funding in support of this translational process. We also treasure the funding support from ITF since 2018 during the early stage of the development of ICVAX. We would also like to express our special thanks to our volunteers in advance for their selfless contributions, without whom we would not be able to carry out this exciting clinical trial."
