VISTA a Potential New Immuno-Oncology Target in Acute Myeloid Leukemia
(ASH 2023)
- "Kineta has developed a fully human monoclonal antibody targeting VISTA, KVA12123, currently evaluated in a Phase 1/2 clinical trial alone and in combination with pembrolizumab in cancer patients with advanced solid tumors...Therefore, we have tested in vivo, in a Kasumi-3 AML disseminated tumor model, the efficacy of our antibody alone or in combination with standard of care therapy, cytarabine and doxorubicin...5mg/kg Dox by IV injections) was initiated in indicated groups for 5 cycles, before starting treatment with KVA12 for the rest of the study...Our data showed that KVA12123 and KVA12402 as single agents and in combination with chemotherapy reduced Kasumi-3 tumor load in the blood, spleen and bone marrow within the groups and significantly improved survival when compared to IgG1 control groups. These data all together indicate that anti-VISTA targeted therapy should be evaluated in myeloproliferative disorders like AML alone or in combination with standard of care."
