UTRECHT, The Netherlands and CAMBRIDGE, Mass., Nov. 09, 2020 (GLOBE NEWSWIRE) -- Merus N.V. (Nasdaq: MRUS) (“Merus”, “the Company”, “we”, or “our”), a clinical-stage oncology company developing innovative, full-length multispecific antibodies (Biclonics® and Triclonics™), today announced that preclinical data from its MCLA-145 program will be presented at the Society for Immunotherapy of Cancer (SITC) annual meeting being held virtually on November 1015, 2020.

“We look forward to sharing data on MCLA-145, our clinical stage Biclonics® bispecific antibody directed at CD137 on T cells and PD-L1 on cancer cells,” said Andrew Joe, M.D., Chief Medical Officer of Merus. “MCLA-145 is the most advanced program in our collaboration with Incyte. In preclinical studies, MCLA-145 demonstrates potent anti-tumor effect and does not appear to exhibit the safety liabilities that have been observed with other potent CD137 agonists.”

MCLA-145 is currently being evaluated in a Phase 1 open-label, multicenter dose escalation study, including a safety dose expansion phase, in patients with solid tumors. MCLA-145 is the first drug candidate co-developed under Merus’ global collaboration and license agreement with Incyte Corporation, which permits the development and commercialization of up to 11 bispecific and monospecific antibodies from our Biclonics® platform. Merus retains full rights to develop and commercialize MCLA-145, if approved, in the United States, and Incyte is responsible for its development and commercialization outside the United States.
