Jubilant Therapeutics Presents Preclinical Data at the American Association for Cancer Research, Reveals Unique Dual-Action Anti-Cancer Mechanism Underscoring First-in-Class Pipeline Asset in Hematological Tumors

Publisher: The Insight Partners

Jubilant Therapeutics Inc., a biopharmaceutical company advancing small molecule modulators to address unmet medical needs in oncology and autoimmune diseases, today announced that preclinical data of dual LSD1 and HDAC6 inhibitor JBI-802, will be presented in a poster session at the American Association for Cancer Research (AACR) 2020 Virtual Annual Meeting II. The preclinical data demonstrated that JBI-802 has strong efficacy in multiple in vivo cancer models mediated by LSD1 and HDAC6 inhibition, while demonstrating excellent selectivity against other HDACs and superior in vivo efficacy compared to single agents targeting LSD1 or HDAC6.

"We are excited to reveal these new data from our study of JBI-802 whose first-in-class dual mechanism of action targets the overexpression of two proteins, while exhibiting a favorable tolerability profile," said Syed Kazmi, President and Chief Executive Officer of Jubilant Therapeutics Inc. "These data support the additional development of this novel dual epigenetic inhibitor as a potential therapeutic agent for genetically-defined cancers."

Key highlights from the study which examined anti-proliferative activity of JBI-802 on select acute myeloid leukemia (AML), chronic lymphocytic leukemia, small cell lung cancer, sarcoma and multiple myeloma cell lines as compared to single agents, include the following:

• JBI-802 demonstrated strong tumor growth inhibition in erythroleukemia and multiple other hematological tumors as compared to single agents;
• Syngeneic models showed single agent activity with unique mechanism of action and that JBI-802 can be combined with checkpoint inhibitors safely in this mouse model; and
• The molecule showed a favorable tolerability profile at efficacious doses.

JBI-802 is currently being evaluated in IND-enabling studies for the treatment of AML and other solid tumors and first-in-human clinical studies are expected in 1H 2021.
