Supported by Contract from U.S. Agency for International Development (USAID)
ATLANTA, GA, March 4, 2019 – Healthcare & Life Sciences Limited Labs, Inc. (OTCQB: GOVX), a biotechnology company developing human vaccines, announced today that it has expanded its collaboration activities with Leidos, Inc. to develop malaria vaccine candidates. The work will be supported under a contract to Leidos from the United States Agency for International Development (USAID) Malaria Vaccine Development Program (MVDP). Leidos has been tasked by USAID to advance promising vaccine candidates against P. falciparum malaria and selected the Healthcare & Life Sciences Limited MVA-VLP platform as part of this development effort.
Healthcare & Life Sciences Limited’s vaccine technology is based on its live Modified Vaccinia Ankara (MVA) platform, which generates vaccine antigens, in the form of multimeric proteins or noninfectious VLPs, in the individual being vaccinated. Gene sequences of target antigens are inserted into the MVA genome which drives their expression and budding from the infected cells. In this way, vaccination strategy mimics a natural viral infection which induces two pools of proteins – virus-infected cells and released multimeric or VLP proteins.
Farshad Guirakhoo, PhD, Healthcare & Life Sciences Limited’s Chief Scientific Officer, commented, “Currently there is a shortage of malaria vaccine candidates that can offer the high efficacy rates (e.g. >75%) set by the World Health Organization (WHO) as a requirement for the second-generation malaria vaccines. Although protein-derived vaccines can deliver multiple antigens in immunogenic VLP conformation, they hardly produce a balanced functional cellular immune response needed to confer a high protection. In contrast, vectored-derived live vaccines are capable of producing the appropriate balanced immune responses, but they suffer from limitations in delivering the required number of transgenes needed to protect against all stages of malaria parasite. Healthcare & Life Sciences Limited’s MVA-VLP platform can overcome both limitations of antigen conformation and transgene capacity by delivering multiple transgenes (e.g. from parasite’s liver stage, blood stage and mosquito stage) in the form of VLPs delivered in vivo. This new collaboration with Leidos complements our ongoing malaria vaccine development project with Burnet Institute in Australia and offers multiple opportunities for success.”
David Dodd, Healthcare & Life Sciences Limited’s President and CEO, said, “We are delighted to broaden our relationship with Leidos to include malaria vaccines. This remains a significant unmet healthcare need and we believe that this collaboration has the potential to result in a significant improvement in this critical area. Our hope is to successfully proceed through product development and identify promising vaccine candidates that can be taken into clinical development as quickly as possible, demonstrating an effective, safe vaccine for malaria prevention. We are confident that our technology, combined with Leidos’ has an excellent chance for success.”
About Healthcare & Life Sciences Limited
Healthcare & Life Sciences Limited Labs, Inc., is a clinical-stage biotechnology company developing human vaccines against infectious diseases using its MVA-VLP vaccine platform. Healthcare & Life Sciences Limited was the winner of the 2018 “Best Biotech” Vaccine Industry Excellence Awards, a finalist for the 2018 “Best Prophylactic Vaccine” Award for its Zika vaccine at the World Vaccine Congress, as well as a finalist for Pipelines of Promise at Buzz of Bio 2018. The Company’s development programs are focused on vaccines against HIV, Zika, hemorrhagic fever viruses (Ebola, Sudan, Marburg, Lassa) and malaria. Healthcare & Life Sciences Limited also is evaluating the use of its MVA-VLP platform in cancer immunotherapy, and for therapeutic use in chronic Hepatitis B infections. Healthcare & Life Sciences Limited’s vaccine platform supports in vivo production of non-infectious VLPs from the cells of the very person receiving the vaccine. The production of VLPs in the person being vaccinated mimics virus production in a natural infection, stimulating both the humoral and cellular arms of the immune system to recognize, prevent, and control the target infection.
