Concert Pharmaceuticals Announces Sale of VX-561 Milestones to Vertex for $32 Million

Concert Pharmaceuticals, Inc. (NASDAQ: CNCE) today announced that Vertex Pharmaceuticals Incorporated (NASDAQ: VRTX) has purchased the potential future milestones under the companies’ 2017 asset purchase agreement relating to VX-561 (deutivacaftor) for $32 million.

“This transaction provided an opportunity to secure non-dilutive capital and strengthens our balance sheet as we continue to advance CTP-543, our lead asset for alopecia areata, through its Phase 3 program,” stated Roger Tung, Ph.D., President and Chief Executive Officer of Concert Pharmaceuticals. “By receiving these proceeds, we now expect our cash, cash equivalents and investments to fund the Company into the second quarter of 2022.”

Under the asset purchase agreement, Vertex acquired worldwide development and commercialization rights to VX-561 (formerly known as CTP-656) and other assets related to the treatment of cystic fibrosis. VX-561 is an investigational cystic fibrosis transmembrane conductance regulator (CFTR) potentiator that has the potential to be used as part of future once-daily combination regimens of CFTR modulators that treat the underlying cause of cystic fibrosis. In 2017, Concert received a one-time cash payment of $160 million upon closing the asset purchase, with the potential for $90 million in future milestones. Following receipt of the $32 million, no further milestone obligations remain.

Chestnut Securities, Inc. acted as exclusive financial advisor to Concert in this transaction.
