– Petosemtamab in combination with pembrolizumab interim data presented at 2024 ASCO® demonstrated robust 67% response rate among 24 evaluable patients
– First patients dosed in phase 3 trial evaluating petosemtamab monotherapy in 2/3L HNSCC, phase 2 trial evaluating petosemtamab in combination with standard chemotherapy in 2L mCRC, and phase 2 trial evaluating MCLA-129 in combination with chemotherapy in 2L+ EGFRm NSCLC
– Based on the Company’s current operating plan, existing cash, cash equivalents, including successful public offering raising $460M gross proceeds, and marketable securities expected to fund Merus’ operations into 2028
UTRECHT, The Netherlands and CAMBRIDGE, Mass., Aug. 01, 2024 (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 financial results for the second quarter and provided a business update.
“Petosemtamab has already demonstrated potential for best in class efficacy with a favorable safety profile in both 1L and 2L+ HNSCC, major areas of unmet medical need. I’m also looking forward to evaluating petosemtamab in mCRC, another potential important opportunity,” said Bill Lundberg, M.D., President, Chief Executive Officer of Merus. “With the addition of Dr. Fabian Zohren as CMO and the recent successful equity financing raising $460M gross proceeds, we are well positioned for our ambitious phase 3 trial plans for petosemtamab in HNSCC and beyond.”
Petosemtamab (MCLA-158: EGFR x LGR5 Biclonics®): Solid Tumors
LiGeR-HN2 phase 3 trial in 2/3L head and neck squamous cell carcinoma (HNSCC) enrolling and LiGeR-HN1 phase 3 trial in 1L HNSCC planned to initiate by year end 2024; phase 2 trial in 2L metastatic colorectal cancer (mCRC) enrolling; clinical data update on 2L+ HNSCC planned for late fourth quarter of 2024
Merus has confirmed through feedback with the U.S. Food and Drug Administration (FDA) that petosemtamab 1500 mg every two weeks is appropriate for further development in HNSCC as monotherapy, and in combination with pembrolizumab.
Merus provided an interim clinical update on petosemtamab with pembrolizumab in 1L HNSCC at the 2024 American Society of Clinical Oncology® (ASCO®) Annual Meeting, demonstrating a 67% response rate among 24 evaluable patients. The oral presentation was detailed in our press release, Merus’ Petosemtamab in Combination with Pembrolizumab Interim Data Demonstrates Robust Response Rate and Favorable Safety Profile in 1L r/m (recurrent/metastatic) HNSCC (May 28, 2024). Merus plans to initiate LiGeR-HN1, a phase 3 trial evaluating petosemtamab in combination with pembrolizumab in 1L HNSCC by year end 2024.
Merus provided an interim clinical update on petosemtamab monotherapy in 2L+ HNSCC at the American Association of Cancer Research® (AACR®) Annual Meeting 2023, demonstrating a 37% response rate among 43 evaluable patients. The oral presentation was detailed in our press release Merus’ Petosemtamab Interim Data Demonstrates Clinically Meaningful Activity in Previously Treated Head and Neck Squamous Cell Carcinoma (HNSCC) (April 17, 2023). Merus plans to provide updated efficacy, durability and safety data of this cohort along with clinical data from the dose optimization cohort evaluating petosemtamab monotherapy 1500 or 1100 mg dose levels in 2L+ HNSCC in late fourth quarter of 2024.
Merus announced the first patient was dosed in LiGeR-HN2, a phase 3 trial evaluating the efficacy and safety of petosemtamab in 2/3L HNSCC compared to standard of care. In this trial, patients will be randomized to petosemtamab monotherapy or investigator’s choice of single agent chemotherapy or cetuximab. This was detailed in our press release, Merus Announces First Patient Dosed in LiGeR-HN2, a Phase 3 Trial Evaluating Petosemtamab in 2/3L r/m HNSCC - Merus (July 24, 2024).
The FDA has granted Breakthrough Therapy Designation (BTD) for petosemtamab for the treatment of patients with recurrent or metastatic HNSCC whose disease has progressed following treatment with platinum based chemotherapy and an anti-programmed cell death receptor-1 (PD-1) or anti-programmed death ligand 1 (PD-L1) antibody. This designation was detailed in our press release, Petosemtamab granted Breakthrough Therapy Designation by the U.S. FDA (May 13, 2024).
Merus believes a randomized registration trial in HNSCC with an overall response rate endpoint could potentially support accelerated approval and the overall survival results from the same study could potentially verify its clinical benefit to support regular approval.
Merus announced the first patient was dosed in the phase 2 open-label trial evaluating the safety and preliminary antitumor activity of petosemtamab with FOLFIRI in 2L mCRC. Trial design was detailed in our press release Merus Announces First Patient Dosed in Phase 2 Trial of Petosemtamab in 2L CRC (July 8, 2024).
Zenocutuzumab (Zeno or MCLA-128: HER2 x HER3 Biclonics®): NRG1 fusion-positive (NRG1+) lung, pancreatic and other solid tumors
Zeno BLA for treatment of NRG1+ non-small cell lung cancer (NSCLC) and pancreatic cancer (PDAC) accepted for priority review by the FDA
The FDA has accepted for priority review a Biologics License Application (BLA) for the bispecific antibody zenocutuzumab (Zeno) in patients with NRG1+ NSCLC and PDAC cancer. This acceptance was detailed in our press release Merus Announces U.S. FDA Acceptance and Priority Review of Biologics License Application for Zeno for the Treatment of NRG1+ NSCLC and PDAC (May 6, 2024).
Merus believes that obtaining a commercialization partnership agreement is an important step in bringing Zeno to patients with NRG1+ cancer, if approved.
MCLA-129 (EGFR x c-MET Biclonics®): Solid Tumors
Investigation of MCLA-129 is ongoing in METex14 NSCLC; phase 2 trial in combination with chemotherapy in 2L+ EGFR mutant (EGFRm) NSCLC enrolling
At 2024 ASCO® Merus presented efficacy and safety data of MCLA-129, in NSCLC with c-MET exon 14 skipping mutations (METex14). This poster presentation was detailed in our press release Merus’ MCLA-129 Demonstrates Promising Single-Agent Efficiency in METex14 NSCLC in Poster Presentation at the 2024 ASCO® Annual Meeting (June 3, 2024).
The first patients were dosed in the phase 2 trial evaluating MCLA-129 in combination with chemotherapy in 2L+ EGFRm NSCLC, with a cohort receiving MCLA-129 and paclitaxel and carboplatin, and another cohort receiving MCLA-129 and docetaxel. We also remain interested in partnering MCLA-129 to sufficiently resource the development of MCLA-129 and the potential benefit it may have for patients.
MCLA-129 is subject to a collaboration and license agreement with Betta Pharmaceuticals Co. Ltd. (Betta), which permits Betta to develop MCLA-129 and potentially commercialize exclusively in China, while Merus retains global rights outside of China.
MCLA-145 (CD137 x PD-L1 Biclonics®): Solid Tumors
Investigation continues of the phase 1 trial of MCLA-145 in combination with pembrolizumab
Interim clinical data on MCLA-145 monotherapy and in combination with pembrolizumab in patients with advanced/metastatic solid tumors were presented at 2024 ASCO®. The oral presentation was detailed in our press release Merus Presents Interim Data on MCLA-145 Monotherapy and in Combination with Pembrolizumab at the 2024 ASCO® Annual Meeting (June 2, 2024).
