Zydus, an innovation-led global healthcare provider and IDRI, a Seattle-based non-profit research and product development organisation are collaborating on the production and clinical development of IDRI’s visceral leishmaniasis (VL) vaccine candidate, designed to prevent the deadly parasitic disease.
Known as Kala-Azar in India, VL is transmitted by the bite of an infected sand fly. There are over 500,000 new VL cases and 50,000 associated deaths each year. VL is the most severe form of leishmaniasis, affecting vital organs, and, if left untreated, the disease can be fatal. A vaccine is considered essential to control and eliminate the disease.
Zydus and IDRI will collaborate to conduct clinical development activities in India with the goal of developing, registering and marketing this vaccine candidate for the prevention of VL, which will achieve the objective of global access – that is, ensuring the vaccine is affordable and accessible to all people in need. Conducting trials in India, where there are real-life situations of disease exposure, is critical to determining the effectiveness of IDRI’s VL vaccine candidate and ensuring it is approved and available within endemic countries.
IDRI’s VL vaccine candidate, LEISH-F3+GLA-SE, is the product of more than 20 years of research and development supported by the US National Institutes of Health (NIH) and the Bill & Melinda Gates Foundation.
The defined, purified, recombinant vaccine comprises two fused Leishmania parasite proteins and an adjuvant to stimulate a protective immune response against the parasite. After completion of a Phase 1 clinical trial of 36 US adult volunteers to test safety and immunogenicity, the vaccine was shown to be safe and to induce potent immune responses in healthy volunteers.
Speaking on the development, Pankaj R Patel, Chairman and Managing Director, Zydus group said, “Zydus has always been committed to working with partners and collaborating to bridge unmet healthcare needs. By partnering with IDRI on this important mission, we will be taking an all important step to eradicate visceral leishmaniasis which is a huge healthcare burden.”
