UTRECHT, The Netherlands and CAMBRIDGE, Mass., Dec. 02, 2021 (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 the publication of the abstract highlighting interim data, as of a July 14, 2021 cutoff, from the phase 1/2 trial of bispecific antibody MCLA-145 in patients with solid tumors. The e-poster will be presented at the ESMO Immuno-Oncology (ESMO IO) Congress 2021 being held December 8-11, 2021 in Geneva, Switzerland.

Presentation Details:

Title: Phase I Dose Escalation Study of MCLA-145, a Bispecific Antibody Targeting CD137 and PD-L1 in Solid Tumors
Poster #: 136P

The e-poster will be available on the virtual platform, in the e-poster section as of Monday, December 6 at 6:00 am ET and on-site at the e-Poster stations starting on Wednesday, December 8. The poster will also be available on the Merus website.

The phase 1, open-label, single-agent clinical trial of MCLA-145 is ongoing. The trial consists of a dose escalation phase, followed by a planned dose expansion phase. MCLA-145 is the first drug candidate co-developed under Merus’ global collaboration and license agreement with Incyte, which permits the development and commercialization of up to 11 bispecific and monospecific antibodies from the Merus Biclonics® platform. Merus retains full rights to develop and commercialize MCLA-145, if approved, in the United States; and Incyte holds full rights to develop and commercialize MCLA-145 outside the United States.

About MCLA-145
Discovered through an unbiased functional screening of multiple immunomodulatory target combinations, MCLA-145 is a Biclonics® T-cell agonist that binds with high affinity and specificity to human PD-L1 and CD137 in preclinical models. The unique immunostimulatory profile of MCLA-145 derives from the potential to potently activate immune effector cells in the context of the tumor microenvironment while simultaneously blocking inhibitory signals in the same immune cell population.
