Lindsay A. Rosenwald, M.D., Fortress' Executive Chairman, President and Chief Executive Officer, said, "We are very pleased that our transaction with Crystalys could potentially expedite the development of dotinurad in the United States and Europe for millions of people suffering from gout, while simultaneously adding value to Fortress and subsidiary company, Urica, through our equity stake in Crystalys and future royalties from dotinurad once commercialized. This significant financing enables the advancement of global pivotal trials which could expeditiously lead to regulatory approval and commercialization of dotinurad in the United States and Europe."
Dr. Rosenwald continued, "In addition to this transaction, Fortress has achieved several key milestones this year including the acquisition of our subsidiary Checkpoint Therapeutics by Sun Pharma, which was a notable validation of our business model, delivering approximately $28 million upfront, plus the potential for an additional contingent value right (CVR) payment and ongoing royalties on future sales of UNLOXCYT (cosibelimab-ipdl). Our goal is to continue to realize value from our extensive portfolio of commercial and clinical-stage assets, while also focusing on new business development opportunities."
