As part of this trial, 146 front-line metastatic pancreatic cancer patients with high serum levels of free IGF-1 will be randomized (1:1) to receive either MM-141 plus nab-paclitaxel/gemcitabine or nab-paclitaxel/gemcitabine alone. Eligible patients for the trial must have received no prior radiotherapy, surgery, chemotherapy or investigational therapy for the treatment of metastatic disease. The primary endpoint of the trial is progression free survival (PFS). Secondary endpoints include overall survival, objective response rate, safety and tolerability. Merrimack plans to conduct the trial at sites in the United States, Canada and Europe. Initial trial sites located at St. Jude Heritage in
MM-141 is a tetravalent bispecific antibody designed to block tumor survival signals by targeting receptor complexes containing IGF-1R and ErbB3 (HER3). IGF-1R and ErbB3 complexes both activate a major signaling pathway that allows tumor cells to grow and develop resistance to chemotherapy. MM-141 has been tested in a Phase 1 dose-escalation clinical trial. The U.S. Food and Drug Administration (FDA) has granted orphan drug designation for MM-141 for the treatment of pancreatic cancer. This orphan drug designation could provide Merrimack with seven-year marketing exclusivity and other benefits for MM-141 when approved by the FDA.
