Merus N.V. (Nasdaq: MRUS) is a clinical-stage immuno-oncology company focused on creating innovative therapies to treat and potentially cure cancer. At the heart of Merus' approach is its proprietary Biclonics® and Triclonics® technology platforms, which generate full-length human bispecific and trispecific antibodies. These advanced therapeutics are designed to engage the immune system to kill tumor cells and inhibit tumor cell growth pathways simultaneously.
Core Business
Merus' core business revolves around the discovery and development of bispecific antibody therapeutics. Their flagship technology, Biclonics®, can attack tumors in multiple ways, making them highly effective against various cancer types. The company’s portfolio includes several promising candidates, such as MCLA-128, which targets HER2 and HER3 receptors in gastric and breast cancers; MCLA-117, targeting AML; MCLA-158 (petosemtamab), focused on head and neck squamous cell carcinoma; and MCLA-145, developed for solid tumors.
Latest Achievements and News
As of May 2024, Merus has received the FDA's Breakthrough Therapy Designation (BTD) for petosemtamab in treating patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) that has progressed after treatment with platinum-based chemotherapy and PD-1/PD-L1 antibodies. This significant milestone is based on the promising data from the ongoing phase 1/2 trial of petosemtamab as a monotherapy, showing substantial improvement in clinically significant endpoints. Furthermore, Merus has announced plans to initiate a phase 3 trial in mid-2024 to evaluate the combination of petosemtamab and pembrolizumab in previously untreated patients.
Additionally, Merus revealed the acceptance of abstracts for MCLA-145 and MCLA-129 at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting. These presentations highlighted the clinical activity of MCLA-145 in advanced solid tumors and the efficacy of MCLA-129 in non-small cell lung cancer (NSCLC).
Financial Condition and Partnerships
Merus has a solid financial foundation, bolstered by strategic partnerships and collaborations. Notably, Merus collaborates with Betta Pharmaceuticals to develop MCLA-129 in China while retaining global rights outside China. The company’s financial strategy includes advancing its clinical development programs and supporting preclinical research and technology development through successful capital raises.

Foundation Medicine has announced a collaboration with Merus N.V. (Nasdaq: MRUS) to develop an RNA platform as a companion diagnostic for Merus's bispecific antibody zenocutuzumab (Zeno). This diagnostic aims to treat patients with neuregulin 1 fusion (NRG1+) cancer. Zeno, which utilizes Merus's Dock & Block® mechanism, inhibits the neuregulin/HER3 tumor-signaling pathway in solid tumors with NRG1 fusions.
The FDA has accepted a Biologics License Application for Zeno under priority review for NRG1+ non-small cell lung cancer (NSCLC) and NRG1+ pancreatic cancer (PDAC). Zeno has also received Breakthrough Therapy Designation for advanced unresectable or metastatic NRG1+ pancreatic cancer and NSCLC. Foundation Medicine's RNA platform offers sophisticated fusion detection in 318 genes through RNA sequencing, potentially helping to detect more NRG1 fusions and inform patient care decisions.
Merus N.V. (Nasdaq: MRUS), a clinical-stage oncology company specializing in innovative multispecific antibodies, has announced its participation in Canaccord Genuity's 44th Annual Growth Conference. Bill Lundberg, M.D., President and CEO of Merus, will present on Tuesday, August 13, 2024, from 9:00-9:25 a.m. ET.

Merus N.V. (Nasdaq: MRUS) has announced the dosing of the first patient in its phase 3 trial (LiGeR-HN2) evaluating petosemtamab in previously treated recurrent/metastatic head and neck squamous cell carcinoma (r/m HNSCC). The trial will compare petosemtamab to investigator's choice of single agent chemotherapy or cetuximab. The FDA has confirmed that the 1500 mg every two weeks dosage is appropriate for further development in HNSCC as monotherapy and in combination with pembrolizumab. This dosage will be used in both the 2/3L phase 3 trial (LiGeR-HN2) and the 1L trial (LiGeR-HN1) in r/m HNSCC. Merus believes petosemtamab has the potential to become the new standard of care across r/m HNSCC.
Merus announced the dosing of the first patient in its phase 2 trial of petosemtamab combined with standard chemotherapy for second-line metastatic colorectal cancer (mCRC). The trial will assess safety and preliminary antitumor activity in approximately 40 patients previously untreated with EGFR inhibitors and without KRAS mutations. This study marks a significant step in Merus' oncology program, expanding from head and neck cancer to mCRC.
