The company has received a $225 million payment which was due from Ipsen, S.A. as a result of its receipt of 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. 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 company announced a special meeting of stockholders on May 10, 2024 to approve a Plan of Dissolution which includes plans for a liquidating dividend payable to stockholders.
