CAMBRIDGE, Mass.--(BUSINESS WIRE)-- Merrimack Pharmaceuticals, Inc. (Nasdaq: MACK) [(“Merrimack” or the “Company”)] today announced its first quarter 2023 financial results for the period ended March 31, 2023. “During the first quarter of 2023 our operating expenses remained consistent with prior quarters and were reduced both by proceeds we received from the receipt of an option fee paid in connection with the entry into an asset purchase option agreement on a preclinical asset and increased interest income” said Gary Crocker, Chairman of Merrimack's Board of Directors. “We continue to be focused on maintaining cash balances that will allow us to be in a position to receive potential milestone payments from Ipsen and Elevation under the programs that we previously sold to them.” First Quarter 2023 Financial Results Merrimack reported a net loss of $271 thousand for the first quarter ended March 31, 2023, or $0.02 per basic and diluted share on a fully diluted basis, compared to a net loss of $132 thousand, or $0.01 per basic and diluted share on a fully diluted basis, for the same period in 2022. Merrimack reported a gain on the sale of assets for the first quarter ended March 31, 2023, of $139 thousand, attributable to an asset purchase option agreement on a preclinical program, compared to $445 thousand related to an asset sale in the same period in 2022. Interest income in the first quarter ended March 31, 2023, was $176 thousand compared to no interest income for the same period in 2022. General and administrative expenses for the first quarter ended March 31, 2023, were $586 thousand, compared to $577 thousand for the same period in 2022. As of March 31, 2023, Merrimack had cash and cash equivalents of $19.4 million, compared to $19.4 million as of December 31, 2022. As of March 31, 2023, Merrimack had 14.3 million shares of common stock outstanding. Updates on Programs Underlying Potential Milestone Payments Ipsen Metastatic Pancreatic Ductal Adenocarcinoma In November 2022, Ipsen announced the Phase III NAPOLI 3 trial of Onivyde (irinotecan liposome injection) plus 5-fluorouracil/leucovorin and oxaliplatin (the “NALIRIFOX regimen”) met its primary endpoint demonstrating clinically meaningful and statistically significant improvement in overall survival compared to nab-paclitaxel plus gemcitabine in 770 previously untreated patients with mPDAC and key secondary efficacy outcome of progression-free survival (PFS) also showed significant improvement over the comparator arm. Ipsen also announced that the safety pro Onivyde in the NAPOLI 3 trial was consistent with those observed in the previous phase I/II mPDAC study. In January 2023, Ipsen presented clinical trial results at the 2023 American Society of Clinical Oncology (ASCO) Gastrointestinal Cancers Symposium. In February 2023 Ipsen provided guidance to investors that it intends to supplemental New Drug Application with the U.S. Food and Drug Administration during the first half of 2023 following the Fast Track Designation granted in 2020 for the use of Onivyde in combination with oxaliplatin plus 5-fluorouracil/leucovorin for the treatment of patients with previously untreated mPDAC. Small Cell Lung Cancer In August 2022, Ipsen announced that the Phase III RESILIENT trial did not meet its primary endpoint of overall survival compared to topotecan. The trial is evaluating Onivyde versus topotecan in patients with small cell lung cancer, who have progressed on or after platinum-based first-line therapy treatment. In the announcement, Ipsen indicated that detailed results from the RESILIENT trial would be presented at an upcoming medical conference. The analysis concluded that the primary endpoint overall survival was not met in patients treated with Onivyde versus topotecan. However, a doubling of the secondary endpoint of objective response rate in favor of Onivyde was observed. In the August 2022 announcement, Ipsen reported that the clinical study results would be communicated with the regulatory agency. Ipsen indicated that while the results from the analysis of the RESILIENT trial have not demonstrated an overall survival benefit with Onivyde in patients in second-line small cell lung cancer, Ipsen intends to analyze the data further before decisions regarding next steps are made. To date, there have been no further announcements by Ipsen regarding these matters and it remains unclear as to whether Ipsen will continue to seek approval for the use of Onivyde in the small cell lung cancer application. If Ipsen elects not to proceed with seeking regulatory approval, or if regulatory approval is not obtained, Merrimack would not be entitled to the $150 million milestone payment tied to FDA approval of Onivyde for treatment of small cell lung cancer. Elevation Oncology In January 2023, Elevation announced it is pausing further investment in the clinical development of seribantumab and intends to pursue further development only in collaboration with a partner. On March 14, 2021 Elevation Oncology announced that it would be presenting two posters on NRG1 fusions, including updated data from the Phase 2 CRESTONE study evaluating seribantumab in patients with solid tumors harboring NRG1 fusions at the American Association for Cancer Research (AACR) Annual Meeting 2023, being held April 14-19, 2023. If Elevation elects not to proceed with seeking regulatory approval, or if regulatory approval is not obtained, Merrimack would not be entitled to the $54.5 million in additional potential development, regulatory approval and commercial-based milestone payments. About Merrimack Merrimack Pharmaceuticals, Inc. is a biopharmaceutical company based in Cambridge, Massachusetts that is entitled to receive up to $450.0 million in contingent milestone payments related to its sale of ONIVYDE® to Ipsen S.A. in April 2017. These milestone payments would be payable by Ipsen upon approval by the U.S. Food and Drug Administration (“FDA”) of ONIVYDE for certain additional clinical indications. ONIVYDE® is already approved by the FDA in combination with fluorouracil (5-FU) and leucovorin (LV) for the treatment of patients with metastatic adenocarcinoma of the pancreas after disease progression following gemcitabine-based therapy. This existing approval is unrelated to any future potential milestone payments. Merrimack’s agreement with Ipsen does not require Ipsen to provide Merrimack with any information on the progress of ONIVYDE clinical trials that is not publicly available. Merrimack is also entitled to receive up to $54.5 million in contingent milestone payments related to its sale of anti-HER3 programs to Elevation Oncology (formerly 14ner Oncology, Inc.) in July 2019. Forward Looking Statements To the extent that statements contained in this press release are not descriptions of historical facts, they are forward-looking statements reflecting the current beliefs and expectations of management made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, as amended. Forward-looking statements include any statements about Merrimack’s strategy, future operations, future financial position, future revenues and future expectations and plans and prospects for Merrimack, and any other statements containing the words “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “plan,” “predict,” “project,” “target,” “potential,” “will,” “would,” “could,” “should,” “continue” and similar expressions. In this press release, Merrimack’s forward-looking statements include, among others, Merrimack’s rights to receive payments related to certain milestone events or whether such milestones will be achieved, if at all, the sufficiency of Merrimack’s cash resources and Merrimack’s strategic plan, including any potential distribution of additional cash. Such forward-looking statements involve substantial risks and uncertainties that could cause Merrimack’s future results, performance or achievements to differ significantly from those expressed or implied by the forward-looking statements. Such risks and uncertainties include, among others: Positive information about pre-clinical and early stage clinical trial results does not ensure that later stage or larger scale clinical trials will be successful. For example, Onivyde® may not demonstrate promising therapeutic effect or appropriate safety profiles in current or later stage or larger scale clinical trials as a result of known or as yet unanticipated side effects. The results achieved in later stage trials may not be sufficient to meet applicable regulatory standards or to justify further development. Problems or delays may arise prior to the initiation of planned clinical trials, during clinical trials or in the course of developing, testing or manufacturing that could lead Ipsen and Elevation Oncology and their partners and collaborators to fail to initiate or to discontinue development. Even if later stage clinical trials are successful, unexpected concerns may arise from subsequent analysis of data or from additional data. Obstacles may arise or issues may be identified in connection with review of clinical data with regulatory authorities. Regulatory authorities may disagree with Ipsen and Elevation Oncology’s view of the data or require additional data or information or additional studies. In addition, the planned timing of initiation and completion of clinical trials based upon Onivyde® and the anti-HER Program are subject to the ability of each of Ipsen and Elevation Oncology, respectively, to enroll patients, enter into agreements with clinical trial sites and investigators, and overcome technical hurdles and other issues related to the conduct of the trials for which each of them is responsible. Additionally, each of Ipsen and Elevation Oncology are subject to the risk that they may not successfully commercialize these development programs. Merrimack is also subject to the risk that it may not have funding sufficient for its foreseeable and unforeseeable operating expenses and capital expenditure requirements. In addition, press releases and other public statements by Ipsen and Elevation Oncology may contain forward-looking statements. Merrimack undertakes no obligation to update or revise any forward-looking statements. Forward-looking statements should not be relied upon as representing Merrimack’s views as of any date subsequent to the date hereof.
