 Lead program Zenocutuzumab remains on track Dr. Andrew Joe appointed Chief Medical Officer Merus extends cash runway into 2H 2022 UTRECHT, The Netherlands and CAMBRIDGE, Mass., Aug. 06, 2020 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 TriclonicsTM, today announced financial results for the second quarter that ended June 30, 2020, and provided a business update.We are pleased to report several updates and progress with our business this quarter, said Bill Lundberg, M.D., President, Chief Executive Officer and Principal Financial Officer of Merus. On the clinical side, Dr. Andrew Joe has been appointed Chief Medical Officer, bringing over 20 years of clinical experience developing cancer therapies, including molecularly-targeted and tumor-agnostic therapies, to the Merus team. On the business side, we have prudently focused our projected spend and anticipate our cash runway will fund our operations into the second half of 2022, putting us in a strong financial position. We look forward to providing a substantive clinical update on zenocutuzumab Zeno for neuregulin 1 NRG1 fusion cancers by year end.Clinical ProgramsZenocutuzumab MCLA-128: HER3 x HER2 Biclonics NRG1 Cancers: Phase 12 eNRGy trial on track for year-end clinical updateMerus continues to enroll patients in the Phase 12 eNRGy trial to assess the safety and anti-tumor activity of zenocutuzumab Zeno monotherapy in NRG1 gene fusion-positive NRG1 solid tumors. The initial clinical responses reported in late 2019 support the potential for Zeno to be particularly effective in patients with NRG1 cancers, a patient population with significant unmet need. Zeno was granted Orphan Drug Designation by the U.S. FDA for pancreatic cancer earlier this year.Over 25 global clinical trial sites for the eNRGy trial are now open, with additional clinical trial sites being added globally. To date, Merus has observed a moderate to high impact on clinical trial enrollment and operations as a consequence of issues related to the COVID-19 pandemic. Merus comprehensive patient recruitment strategy includes agreements with Caris Life Sciences Caris, Foundation Medicine Inc. and Tempus Labs Inc., to identify NRG1 patients and determine suitability of enrollment of these patients in the eNRGy trial and Early Access Program EAP. In July 2020, Merus separately announced a collaboration with Caris to identify patients with NRG1 cancers for potential participation in the eNRGy trial and EAP. This agreement with Caris focuses on screening for pancreatic cancer. Caris has agreed to provide tumor DNA and RNA molecular testing in this patient population that may otherwise not undergo molecular diagnostic testing due to the current lack of personalized, molecularly-driven treatment options for this cancer type.Details of the eNRGy trial, including current trial sites, can be found at and Merus trial website at or by calling 1-833-NRG-1234.MCLA-117 CLEC12A x CD3 Biclonics: Acute Myeloid Leukemia AML MCLA-117 Phase 1 interim data presented at ASCO Virtual Meeting MCLA-117 is a first-in-class bispecific Biclonics T-cell engager antibody that is designed to engage CD3 on T-cells and to bind to and kill AML blasts via the CLEC12A antigen. It is being evaluated in a Phase 1 open-label, multicenter dose escalation study in patients with AML. In May, Merus announced that MCLA-117 demonstrated clinical activity in terms of T-cell activation, mild to moderate cytokine release syndrome and blast count reductions in some patients and at some dose cohorts. However, Merus does not plan to continue enrollment into dose expansion cohorts in the trial. Insights from this trial are being used to inform and maximize development of our CD3 T-cell engager platform, which includes a panel of more than 175 novel and diverse T-cell CD3 fragment antigen-binding Fab binders across a wide range of affinities and attributes.MCLA-158 Lgr5 x EGFR Biclonics: Solid Tumors Phase 1 trial continues: Update expected by year endMCLA-158 is currently being evaluated in a Phase 1 open-label, multicenter dose escalation study, including a safety dose expansion phase, in patients with solid tumors. The trial is ongoing and MCLA-158 has demonstrated a favorable safety profile with no observed dose limiting toxicities to date. Merus plans to provide a clinical update on the Phase 1 trial by year end. MCLA-145 CD137 x PD-L1 Biclonics: Solid Tumors Phase 1 trial advancing as plannedMCLA-145 is currently being evaluated in a Phase 1 open-label, multicenter dose escalation study, including a safety dose expansion phase, in patients with solid tumors. MCLA-145 is the first drug candidate co-developed under Merus global collaboration and license agreement with Incyte Corporation, which permits the development and commercialization of up to 11 bispecific and monospecific antibodies from our Biclonics platform. Merus retains full rights to develop and commercialize MCLA-145, if approved, in the United States, and Incyte is responsible for its development and commercialization outside the United States.MCLA-129 EGFR x c-MET Biclonics: Solid Tumors IND-enabling studies ongoingMerus is currently conducting IND-enabling studies of MCLA-129 for the treatment of various solid tumors in collaboration with Betta Pharmaceuticals Betta. Merus presented preclinical data in late 2019 demonstrating that MCLA129 inhibited the growth of tyrosine kinase resistant Non-Small Cell Lung Cancer NSCLC cell lines and NSCLC tumors in xenograft models. Betta holds exclusive rights to develop MCLA-129 in China, while Merus retains full exChina rights.Corporate ActivitiesDr. Andrew Joe appointed Chief Medical Officer In July, Merus appointed Dr. Andrew Joe as Chief Medical Officer.
