HOUSTON and SINGAPORE, May 31, 2021 /PRNewswire/ -- Hummingbird Bioscience, an innovative clinical-stage biotech company focused on developing precision therapies against hard-to-drug targets today announced that its abstract reporting pre-clinical results from its V-domain immunoglobulin suppressor of T cell activation (VISTA) antibody, HMBD-002, has been selected for publication at the American Society of Clinical Oncology (ASCO) Annual Meeting, to be held June 4-8, 2021.
The abstract reports pre-clinical studies that demonstrate HMBD-002's ability to induce an effective anti-tumor immune response, both as a monotherapy and in combination with the checkpoint inhibitor pembrolizumab in multiple syngeneic and humanized xenograft models.
HMBD-002 is the only IgG4 isotype anti-VISTA antibody currently in development for the treatment of cancers with VISTA-mediated immune suppression, including triple negative breast cancer and non-small cell lung cancer. The Phase 1 clinical trial for HMBD-002 is anticipated to commence later this year.
The full abstract is now available on ASCO's Meeting Library: https://meetinglibrary.asco.org/record/200356/abstract
Details of the publication are as follows:

About HMBD-002
HMBD-002 is a unique anti-VISTA neutralizing antibody, and the only IgG4 isotype anti-VISTA antibody currently in development. It was engineered to bind to VISTA at a specific site that is predicted to be essential for ligand-binding and function, thus inhibiting VISTA and neutralizing its immunosuppressive activity without depleting VISTA expressing cells that play many important roles in the immune system.
Pre-clinical studies have shown that HMBD-002 as a monotherapy inhibits tumor growth and significantly prolongs survival, with no observed toxicity. It has also shown synergy when used in combination with anti-PD-1 therapy.
HMBD-002 is being developed for multiple cancers that have strong evidence of VISTA mediated suppression both as a monotherapy and in combination with PD-1 inhibitor.
Hummingbird's first-in-class anti-VISTA therapeutic antibody is advancing to clinical trials with support from a US$13.1 million product development grant from the Cancer Prevention and Research Institute of Texas (CPRIT).
