CAMBRIDGE, MA, USA I February 23, 2023 I Blueprint Medicines Corporation (NASDAQ: BPMC) today announced it will regain global commercialization and development rights to GAVRETO® (pralsetinib), excluding Greater China, following a decision by Roche to discontinue the collaboration agreement between the companies for GAVRETO for strategic reasons.

Under the terms of the agreement, the termination will be effective 12 months from the notification date of February 22, 2023. During the transition period, Blueprint Medicines and Roche are mutually committed to ensuring a smooth transition process with no anticipated interruptions or changes to patient access. In addition, the company will explore options to advance and simplify the continued global commercialization and development of GAVRETO.

“At Blueprint Medicines, we are dedicated to driving innovation and changing outcomes for patients with lung cancer. GAVRETO is an important treatment option for patients with RET fusion-positive lung cancer and other RET-altered cancers, and we are committed to ensuring that patients being treated with GAVRETO in the commercial and clinical trial settings continue to have access,” said Kate Haviland, Chief Executive Officer of Blueprint Medicines. “Over the next year, we will work alongside Roche to transition the GAVRETO program. In parallel, Blueprint will determine the optimal path forward to bring GAVRETO to patients in a way that maximizes its impact and value. As we do this, we will remain focused on our 2023 goals, with our highest priorities being the anticipated U.S. launch of AYVAKIT® (avapritinib) in indolent systemic mastocytosis and the ongoing advancement of our pipeline of investigational medicines.”

Since the initiation of the collaboration with Roche in July 2020, Blueprint Medicines has benefited from approximately $1 billion between upfront and milestone payments and from cost-sharing the commercialization and development of GAVRETO. The company anticipates no impact to its 2023 revenue guidance, which includes $40 million to $50 million in collaboration revenues from existing collaborations, or its anticipated operating expenses in 2023. In addition, the company continues to expect that its existing cash, cash equivalents and investments, together with anticipated future product revenues, will provide sufficient capital to enable the company to achieve a self-sustainable financial profile.
