– 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 1/2 eNRGy trial on track for year-end clinical updateMerus continues to enroll patients in the Phase 1/2 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 www.ClinicalTrials.gov and Merus’ trial website at www.nrg1.com, 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 MCLA‑129 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 ex‑China rights.Corporate ActivitiesDr. Andrew Joe appointed Chief Medical OfficerIn July, Merus appointed Dr. Andrew Joe as Chief Medical Officer. Dr. Joe oversees all clinical and regulatory strategy and activities at Merus. He brings over 20 years of experience in clinical drug development and translational research within industry and academic medicine. Dr. Joe most recently led the immuno-oncology program at Sanofi, which included co-development of LIBTAYO® (cemiplimab-rwlc) with Regeneron in skin, lung and other cancers. Previously at Merck Sharp & Dohme Corp., he led the KEYTRUDA® (pembrolizumab) New Indications Development Team in obtaining the first tumor/histology-agnostic drug approval in Microsatellite Instability-High (MSI-H) cancer, and the first immuno-oncology drug approval in a gynecological malignancy (cervical cancer). Dr. Joe also played key roles at Novartis in the global approval of Zykadia® (ceritinib) in ALK-positive lung cancer and at Roche in the global approval of ZELBORAF® (vemurafenib) in BRAF-mutant metastatic melanoma. Dr. Joe is an Assistant Professor of Medicine at Columbia University Irving Medical Center. He received B.S. degrees in chemistry and biology from the Massachusetts Institute of Technology and an M.D. from the Mount Sinai School of Medicine.Cash Runway Extended Two Quarters into 2H 2022Based on the Company’s current operating plan, Merus expects its existing cash, cash equivalents and marketable securities will be sufficient to fund its operations into the second half of 2022. This represents an expected extension of the cash runway by approximately two quarters, and is based on the program decisions, including no longer planning to enroll the previously planned dose expansion cohort in the MCLA-117 program, lowering general and administrative costs and travel expenses, in part due to COVID-19, and reducing planned personnel and other spend across programs and functions.
