MCLA-129 in combination with chemotherapy in 2L+ EGFRm NSCLC planned to initiate 1Q24

UTRECHT, The Netherlands and CAMBRIDGE, Mass., Dec. 02, 2023 (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 updated interim clinical data on MCLA-129 from ongoing expansion cohorts in non-small cell lung cancer (NSCLC) and in previously treated head and neck squamous cell carcinoma (HNSCC) were presented at the European Society for Medical Oncology (ESMO) Asia Congress 2023.

“MCLA-129 is a very active drug in EGFRm NSCLC and we’re planning a focused investment to evaluate MCLA-129 in combination with chemotherapy, which we expect to start early in 2024,” said Bill Lundberg M.D., President, Chief Executive Officer of Merus. “We are in a fortunate position to have a strong balance sheet. We also recognize the importance of being responsible with our resources to maintain financial strength, as we plan to initiate a phase 3 trial of petosemtamab in 2L+ HNSCC by mid-2024.”  

The reported data are from three expansion cohorts in the open label trial evaluating MCLA-129 in combination with osimertinib, a third generation EGFR TKI, in treatment-naïve EGFR mutant (m) NSCLC (1L) and in EGFRm NSCLC that has progressed on osimertinib (2L+), as well as MCLA-129 monotherapy in previously treated HNSCC.

Efficacy and safety of MCLA-129, an EGFR x c-MET bispecific antibody, combined with osimertinib, as first-line therapy or after progression on osimertinib in non-small cell lung cancer (NSCLC)

    • Treatment emergent adverse events (TEAEs) led to discontinuations in 14 (23%) pts
    • Treatment related interstitial lung disease (ILD)/pneumonitis in 13 pts (22%), four were G1, two were G2, four were G3, and three were G5

About MCLA-129
MCLA-129 is an antibody-dependent cellular cytotoxicity-enhanced Biclonics® that is designed to inhibit the EGFR and c-MET signaling pathways in solid tumors. Preclinical data have shown that MCLA-129 can effectively treat TKI-resistant NSCLC in xenograft models of cancer. MCLA-129 is designed to have two complementary mechanisms of action: blocking growth and survival pathways to stop tumor expansion and recruitment and enhancement of immune effector cells to eliminate the tumor.
