- MCLA-128’s unique mechanism of action published in the scientific journal Cancer Cell -
UTRECHT, The Netherlands, July 26, 2018 (GLOBE NEWSWIRE) -- Merus N.V. (Nasdaq:MRUS) (“Merus”, “we”, “our” or the “Company”), a clinical-stage immuno-oncology company developing innovative bispecific antibody therapeutics (Biclonics®), today announced financial results for the first quarter ended March 31, 2018 and provided a corporate and clinical update.
“In May, we advanced MCLA-158, a Biclonics® designed to bind to cancer-initiating cells expressing Lgr5 and EGFR, into the clinic with the commencement of patient dosing in a Phase 1, first-in-human clinical trial in patients with solid tumors,” said Ton Logtenberg, Ph.D., Chief Executive Officer of Merus. “Clinical trials for MCLA-128 and MCLA-117 are ongoing. Potential early activity data for MCLA-117 is expected in 2018, and we anticipate reporting data for MCLA-128 later this year.”
Dr. Logtenberg continued, “Notably, the unique mechanism of action of MCLA-128 was recently published in the scientific journal Cancer Cell and highlighted the screening of a panel of more than 500 bispecific antibodies binding to the HER2/HER3 target pair in relevant functional assays. This unbiased functional screening led to the identification of development candidate MCLA-128, a bispecific antibody that employs a unique mechanism, DOCK & BLOCK®, for the selective and potent inhibition of the heregulin/HER3 tumor-signaling pathway. These results reinforce the potential of our functional screening process that allows for the discovery of unique biology driven by the bispecific antibody format.”
Recent Clinical & Corporate Developments
- Patient Dosing Commenced in a Phase 1 Clinical Trial of MCLA-158 in Patients with Solid Tumors - Merus announced in May 2018 that the first patient was dosed in a Phase 1, first-in-human clinical trial of MCLA-158 in patients with solid tumors with an initial focus on metastatic colorectal cancer. The trial consists of two parts, a dose escalation and a dose expansion. The dose escalation part is intended to determine the appropriate dose of MCLA-158. The dose escalation and expansion parts of the trial will also examine the preliminary antitumor activity of single-agent MCLA-158.
- DOCK & BLOCK® Mechanism of Action (MOA) of MCLA-128 Published in Cancer Cell –The MOA of MCLA-128, the Company’s most-advanced Biclonics® candidate that binds to HER2 and HER3-expressing solid tumor cells and potently blocks the heregulin/HER3 tumor-signaling pathway, was published in the May 2018 edition of Cancer Cell titled, “Unbiased Combinatorial Screening Identifies a Bispecific IgG1 that Potently Inhibits HER3 Signaling via HER2-Guided Ligand Blockade.” Using a structure function approach, Merus demonstrated that PB4188, the research candidate described in the paper, employs a unique mechanism to inhibit the growth of tumors by docking to HER2 and blocking ligand interaction with HER3, thereby preventing stabilization of the HER2:HER3 heterodimer and sustained signaling. MCLA-128, the development candidate of PB4188, is currently being studied in a Phase 2 combination trial in two metastatic breast cancer populations and a Phase 1/2 study evaluating single-agent activity for MCLA-128 in gastric, ovarian, endometrial and non-small cell lung cancer (NSCLC).
- Awarded Fees and Costs in Regeneron Patent Litigation - On June 25, 2018, in a decision which published on July 10, 2018, the United States District Court for the Southern District of New York granted Merus’ motion for approximately $10.5 million of attorneys’ fees, expert fees and costs, plus pre- and post-judgment interest, incurred by Merus in its defense of Regeneron Pharmaceutical Inc.’s suit initiated in March 2014. The District Court’s decision recounts Regeneron’s inequitable conduct before the United States Patent and Trademark Office while prosecuting the U.S. Patent No. 8,502,018 (the ‘018 patent), entitled "Methods of Modifying Eukaryotic Cells."
Anticipated 2018 Milestones
MCLA-128, an antibody-dependent cell-mediated cytotoxicity (ADCC) enhanced Biclonics® that binds to HER2 and HER3-expressing solid tumor cells
The Phase 1/2 study evaluating single-agent activity for MCLA-128 in various solid tumor indications is ongoing and Merus expects to provide an update on the gastric cohort in the fourth quarter of 2018.
MCLA-117, a Biclonics® that binds to CD3 and CLEC12A
Merus is continuing dose escalation in the Phase 1 clinical trial of MCLA-117 in Europe and the U.S. Safety and potential early activity data is expected in the second half of 2018.
MCLA-158, an ADCC-enhanced Biclonics® designed to bind to cancer stem cells expressing Lgr5 and EGFR
Recruitment for the Phase 1 clinical trial of MCLA-158 in patients with solid tumors is ongoing. The trial is being conducted in Europe and the U.S.
MCLA-145, a Biclonics® designed to bind to PD-L1 and a second undisclosed immunomodulatory target
MCLA-145, the first drug candidate co-developed under the Merus and Incyte global research collaboration, continues to progress in IND-enabling studies. Merus has full rights to develop and commercialize MCLA-145 in the U.S. and Incyte is responsible for its development and commercialization outside the U.S.
First Quarter 2018 Financial Results
Merus ended the first quarter of 2018 with cash, cash equivalents and investments of €220.1 million compared to €190.8 million at December 31, 2017, the increase primarily being the result of the closing of a $55.8 million (€44.8 million) private placement of 3.1 million common shares completed in February 2018.
Total revenue for the three months ended March 31, 2018 was €9.9 million compared to €3.9 million for the same period in 2017. Revenue for the three months ended March 31, 2017 has been restated for the adoption of IFRS 15, a new accounting standard related to revenue recognition. Under IFRS 15, Merus reduced the period that it amortizes revenue for the upfront license payment received from Incyte from 21 years to 9 years which resulted in €1.6 million of additional revenue for the three months ended March 31, 2017. Revenue is comprised primarily of the amortization of upfront license payments from Merus’ collaboration agreements and collaboration income related to cost reimbursements and research milestones for performance of research and development services under the respective agreements.
The increase in revenue for the period is attributable to €1.9 million of amortization of upfront license payments, €1.6 million of collaboration income for expense reimbursements and €2.5 million for research milestones earned under Merus’ agreement with Ono Pharmaceuticals.
Research and development costs for the three months ended March 31, 2018 were €10.3 million compared to €7.0 million for the same period in 2017. The increase in research and development costs reflects higher enrollment in Merus’ clinical trials, expansion of research efforts to support its internal programs and collaborations and additional manufacturing expenses.
Management and administration costs for the three months ended March 31, 2018 were €2.9 million compared to €4.2 million for the same period in 2017. The decrease relates primarily to lower share-based compensation expenses.
Other expenses for the three months ended March 31, 2018 were €2.7 million compared to €1.8 million for the same period in 2017. The increase in other expenses was the result of higher consulting, accounting and professional fees.
For the three months ended March 31, 2018, Merus recorded a net loss of €8.4 million, or €(0.40) per share (basic and diluted), compared to a net loss of €19.7 million, or €(1.06) per share (basic and diluted), for the same period in 2017. The net loss for the three months ended March 31, 2017 included a non-cash charge of €10.7 million for the accounting impact of a financial derivative related to the obligation to deliver shares to Incyte in 2017.
Based on the Company’s current operating plan, Merus expects that its existing cash, cash equivalents and investments will be sufficient to fund its operations through the end of 2020.
