UTRECHT, The Netherlands and CAMBRIDGE, Mass., Feb. 28, 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 fourth quarter and full year and provided a business update.
“2024 is poised to be a transformational year for Merus. For petosemtamab, we plan to start a phase 3 registration trial in 2L+ HNSCC in mid-2024. In the first-line setting, we plan to provide initial data on the combination with pembrolizumab in the second quarter and are preparing for a potential first-line phase 3 trial. This year, we also plan to evaluate petosemtamab in 2L colorectal cancer,” said Bill Lundberg, M.D., President, Chief Executive Officer of Merus. “Additionally, for Zeno we are preparing our first potential BLA submissions in NRG1+ lung and NRG1+ pancreatic cancer. We are also excited by continued enhancements to our productive Multiclonics® platforms, which serve as our engine to develop innovative antibodies both for our own pipeline and for our collaborators.”
Petosemtamab (MCLA-158: EGFR x LGR5 Biclonics®): Solid Tumors
Phase 3 registration trial in 2L+ head & neck squamous cell carcinoma (HNSCC) on track to initiate mid-2024; dose comparison of petosemtamab monotherapy 1100 vs 1500 mg in previously treated (2L+) HNSCC ongoing; evaluation in combination with pembrolizumab as first-line (1L) therapy ongoing; planned initiation of 2L colorectal cancer (CRC) cohort in 2024
Merus plans to initiate a phase 3 clinical trial in mid-2024 to evaluate petosemtamab monotherapy in 2L+ HNSCC. In the planned trial, patients will be randomized to petosemtamab monotherapy or investigators’ choice of single agent chemotherapy or cetuximab. Merus believes a randomized registration trial in HNSCC with an overall response rate (ORR) endpoint could potentially support accelerated approval and the overall survival (OS) results from the same study could potentially verify its clinical benefit to support regular approval.
Merus continues to evaluate approximately 40 patients treated with petosemtamab monotherapy at either 1100 or 1500 mg dose levels to confirm a suitable dose for future potential phase 3 trials. Merus plans to share clinical data from this cohort in the second half of 2024.
Merus also continues to evaluate patients with untreated advanced PD-L1+ HNSCC treated with petosemtamab 1500 mg in combination with pembrolizumab. Initial safety data from this single arm cohort may support the initiation of a 1L phase 3 trial with this combination. Among the initial patients dosed in the 1L combination cohort, the safety profile has been observed to be generally favorable. Merus plans to report initial interim efficacy and safety data from this cohort in the second quarter of 2024.
At the American Association of Cancer Research (AACR) Annual Meeting 2023, Merus provided interim data on 49 2L+ HNSCC patients that were treated with petosemtamab at the recommended phase 2 dose of 1500 mg intravenous every two weeks. 43 patients were evaluable for efficacy. As of a February 1, 2023 data cutoff date, the ORR was 37.2% by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 per investigator assessment. Petosemtamab continued to demonstrate a manageable safety profile. Merus plans to provide updated efficacy, durability and safety data of this cohort in the second half of 2024.
The U.S. Food & Drug Administration (FDA) has granted Fast Track Designation (FTD) 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 protein 1 (anti-PD-1) antibody. FTD is designed to facilitate the development and expedite the review of drugs to treat serious conditions and fill unmet medical needs.
In 2024, Merus is planning to initiate the evaluation of petosemtamab monotherapy in 2L CRC.
Zenocutuzumab (Zeno or MCLA-128: HER2 x HER3 Biclonics®): NRG1 fusion-positive (NRG1+) lung, pancreatic and other solid tumors
Sufficient clinical data expected in 1H24 to support potential BLA submissions in NRG1+ non-small cell lung cancer (NSCLC) and NRG1+ pancreatic cancer (PDAC)
Zeno is being investigated in the phase 1/2 eNRGy trial and Early Access Program (EAP) which are assessing the safety and anti-tumor activity of Zeno monotherapy in NRG1+ cancer.
In 2023, Merus met with the FDA and based on these productive and collaborative discussions, the Company believes it will have sufficient clinical data in the first half of 2024 to support potential Biologics License Application (BLA) submissions in NRG1+ NSCLC and NRG1+ PDAC.
Merus believes that obtaining a commercialization partnership agreement will be an essential step in bringing Zeno to patients with NRG1+ cancer, if approved.
In 2023, the FDA granted Breakthrough Therapy Designation (BTD) to Zeno for the treatment of patients with advanced unresectable or metastatic NRG1+ pancreatic cancer following progression with prior systemic therapy or who have no satisfactory alternative treatment options. Additionally, the FDA granted BTD to Zeno for the treatment of patients with advanced unresectable or metastatic NRG1+ NSCLC, following progression with prior systemic therapy.
Merus shared updated interim clinical data on our Zeno program (eNRGy trial and EAP) in patients with NRG1+ NSCLC and NRG1+ PDAC at the European Society for Medical Oncology (ESMO) Congress 2023. In 78 evaluable NRG1+ NSCLC patients, as of a July 31, 2023 data cutoff date, a 37% ORR per RECIST v1.1 by investigator assessment and 14.9 months median duration of response (DOR) was reported. In 33 evaluable NRG1+ PDAC patients, a 42% ORR per RECIST v1.1 by investigator assessment and 9.1 months median DOR was reported. Zeno continued to demonstrate a well-tolerated safety profile.
Merus also evaluated patients with castration resistant prostate cancer (CRPC) treated with Zeno in combination with an androgen deprivation therapy (enzalutamide or abiraterone), irrespective of NRG1+ status. Enrollment is complete and Merus plans to continue monitoring these patients. The Company also continues to monitor and evaluate patients treated with Zeno in combination with afatinib but no further enrollment is planned at this time.
The Company is also conducting ongoing translational work on potential biomarkers outside of NRG1+ cancer which may support development opportunities for Zeno in additional areas of unmet need.
MCLA-129 (EGFR x c-MET Biclonics®): Solid Tumors
Investigation of MCLA-129 continues in the MET ex14 NSCLC expansion cohort in the phase 1/2 trial; MCLA-129 in combination with chemotherapy in 2L+ EGFR mutant (EGFRm) NSCLC planned to start in 2024
MCLA-129 is in clinical development in a phase 1/2, open-label clinical trial evaluating MCLA-129 monotherapy in patients with MET ex14 NSCLC and Merus plans to start a cohort of MCLA-129 in combination with chemotherapy in 2L+ EGFRm NSCLC in 2024.
In December at the ESMO Asia Congress 2023 interim data was presented on MCLA-129 from ongoing expansion cohorts in NSCLC and in previously treated HNSCC. Patients with advanced/metastatic EGFRm NSCLC were treated with MCLA-129 combined with osimertinib as first-line therapy or in the 2L+ setting after progression on osimertinib. In the 1L setting, all 16 evaluable patients experienced tumor shrinkage. In the 2L+ setting, 34 patients were evaluable for response with 11 experiencing confirmed PRs and 1 unconfirmed PR by RECIST v1.1. per investigator assessment. We continue to monitor these patients and evaluate potential for biomarkers to maximize efficacy, while proactively addressing safety signals seen to date.
We also remain interested in exploring partnering MCLA-129 with other companies to sufficiently resource the development of MCLA-129 and 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
MCLA-145 is in clinical development in a global, phase 1, open-label, clinical trial evaluating MCLA-145 in patients with solid tumors. The trial is in the dose expansion phase, with the Company monitoring and evaluating patients on treatment with the combination of MCLA-145 with pembrolizumab.
