SUZHOU, China, Dec. 10, 2020 /PRNewswire/ -- The partner of CStone Pharmaceuticals ("CStone", HKEX: 2616), Blueprint Medicines, announced on December 1^st that the U.S. Food and Drug Administration (FDA) has approved GAVRETO™ (pralsetinib) for the treatment of patients with RET-altered thyroid cancers. The accelerated approval expands the labeled indications for GAVRETO to include adult and pediatric patients 12 years of age and older with advanced or metastatic RET-mutant medullary thyroid cancer who require systemic therapy, or with advanced or metastatic RET fusion-positive thyroid cancer who require systemic therapy and who are radioactive iodine-refractory (if radioactive iodine is appropriate). Continued approval for these indications may be contingent upon verification and description of clinical benefit in confirmatory trials.

"We are pleased that pralsetinib has been approved by the U.S. FDA for the treatment of patients with RET-altered thyroid cancers," said Dr. Frank Jiang, Chairman and CEO of CStone, " In China, the National Medical Products Administration has accepted pralsetinib's new drug application with priority review designation for the treatment of patients with RET fusion-positive non-small cell lung cancer. We hope to deliver pralsetinib to a wide range of patients with RET-altered cancers in China."
