Merrimack Pharmaceuticals, Inc. (Nasdaq: MACK) (“Merrimack” or the “Company”) today announced its full year 2023 financial results for the period ended December 31, 2023.

“As Ipsen reported in February, the U.S. Food and Drug Administration has approved the supplemental new drug application for Onivyde® (irinotecan liposome injection) plus 5 fluorouracil/leucovorin and oxaliplatin (NALIRIFOX) as a first-line treatment for people living with metastatic pancreatic ductal adenocarcinoma (mPDAC),” said Gary Crocker, CEO and Chairman of Merrimack’s Board of Directors. “This approval triggers a $225 million payment which is due from Ipsen to Merrimack before the end of March. We expect to hold a special meeting of stockholders to approve a Plan of Dissolution and a liquidating dividend payable to stockholders. We currently anticipate the initial liquidating dividend to be in the range of between approximately $14.65 and $15.35 per share.”

Updates on Programs Underlying Potential Milestone Payments and Planned Dissolution

On February 13, 2024, we announced that Ipsen S.A. announced it had received approval from the U.S. Food and Drug Administration, or FDA, to market ONIVYDE as a first-line treatment of metastatic adenocarcinoma on the pancreas. As a result of this approval by the FDA, we are entitled to receive a $225 million milestone payment from Ipsen, which is expected to be received by the end of March 2024.

Merrimack’s Board of Directors has evaluated the likelihood of receiving additional milestone payments under the Ipsen Agreement and from the 2019 Agreement with Elevation Oncology and has concluded that it is unlikely that any additional milestone payments from either agreement will become payable. The Plan of Dissolution will include establishment of a liquidating trust for the benefit of stockholders in the unlikely event that Merrimack might receive any future milestone payments from Ipsen or Elevation Technology.

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. $225 million of these potential milestone payments are tied to the first line metastatic pancreatic ductal adenocarcinoma potential indication and are expected to be received by the end of March. The remaining milestone payments consist of $150 million tied to the small cell lung cancer potential indication and $75 million is tied to other potential applications Ipsen may elect to pursue. 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. 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.
