Nimbus Therapeutics Presents In Vivo Data Showing Single-Agent and Combination Activity of HPK1 Inhibitor

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Nimbus Therapeutics, a biotechnology company designing breakthrough medicines through structure-based drug discovery and development, today announced the presentation of data from the company’s HPK1 inhibitor program in a poster at the AACR Annual Meeting held virtually April 10-15, 2021.

Newly disclosed data show that Nimbus’ small-molecule HPK1 inhibitor, NMBS-2, demonstrates significant tumor growth inhibition as a single agent and in combination with anti-PD1 in multiple mouse syngeneic tumor models. In combination with anti-PD1, NMBS-2 restored cytokine secretion from exhausted human T cells and induced robust tumor growth inhibition in the CT-26 model. Furthermore, animals treated with NMBS-2 and anti-PD1 showed complete rejection of subsequently reintroduced CT-26 tumor cells, suggesting the establishment of a robust and durable immune memory.

“Building on our promising findings to date demonstrating the anti-tumor immune activity of NMBS-2, these latest data provide a compelling picture of its potential clinical utility in a range of tumor types — both as a single agent and as a combination therapy with anti-PD1 treatment,” said Peter Tummino, Ph.D., Chief Scientific Officer of Nimbus. “We’re rapidly progressing IND-enabling studies of NMBS-2 now with plans to initiate first-in-human studies in the second half of 2021.”
