Bristol-Myers Squibb Company and Promedior, Inc. announced that the companies have entered into an agreement that grants Bristol-Myers Squibb an exclusive right to acquire Promedior and gain worldwide rights to its lead asset PRM-151, a recombinant form of human pentraxin-2 protein in Phase 2 development for the treatment of idiopathic pulmonary fibrosis (IPF) and myelofibrosis (MF). PRM-151 has been granted Fast Track designation in the U.S. and Orphan designation in the U.S. and Europe for the treatment of MF and Orphan Designation in the U.S. and Europe for the treatment of IPF. Total aggregate payments to Promedior under the agreement have the potential to reach $1.25 billion, which includes an upfront cash payment for the right to acquire Promedior, an exercise fee payable if Bristol-Myers Squibb elects to exercise its right to acquire the company, and subsequent clinical and regulatory milestone payments.
PRM-151 has been shown in multiple preclinical models to regulate monocytes and macrophages at areas of tissue damage to prevent and reverse fibrosis, including IPF, acute and chronic nephropathy, liver fibrosis, and age-related macular degeneration. Promedior has advanced PRM-151 into clinical trials focused on two orphan fibrotic diseases (MF and IPF). It is anticipated that the Phase 2 trials in MF and IPF will be initiated in the coming weeks. Bristol-Myers Squibb can exercise its right to acquire Promedior upon completion of either of these trials.
