CStone Announces New Drug Approval of GAVRETO(R) (pralsetinib) as First Selective RET Inhibitor in China, Providing a New Therapy for a Subset of Non-Small Cell Lung Cancer Patients

  • GAVRETO has been approved for the treatment of adults with locally advanced or metastatic RET fusion-positive non-small cell lung cancer after platinum-based chemotherapy
  • GAVRETO is the first approved selective RET inhibitor in China and first approved precision therapy for CStone

SUZHOU, China, March 24, 2021 /PRNewswire/ -- CStone Pharmaceuticals (CStone, HKEX: 2616), a leading biopharmaceutical company focused on developing and commercializing innovative immuno-oncology therapies and precision medicines, today announces that the National Medical Products Administration (NMPA) of China has approved GAVRETO® (pralsetinib) capsules for the treatment of adult patients with locally advanced or metastatic rearranged during transfection (RET) fusion-positive non-small cell lung cancer (NSCLC) after platinum-based chemotherapy. Discovered by CStone's partner Blueprint Medicines, GAVRETO is China's first approved selective RET inhibitor, as well as CStone's first approved precision therapy in China.

Dr. Frank Jiang, Chairman and CEO of CStone, noted: "This is a key milestone for CStone. The approval of GAVRETO in China reflects CStone's commitment to research and develop innovative therapies to meet patients' unmet medical needs as well as strong execution capabilities. We would like to thank all the patients and investigators involved in the clinical study and extend our gratitude to the NMPA and other government authorities for their support in the priority review leading to the fast approval of GAVRETO. We continue to advance the development of GAVRETO in other indications such as first-line NSCLC, thyroid cancer and other solid tumors, aiming to bring the treatment to more patients soon."

Professor Yi-long Wu of Guangdong Provincial People's Hospital, a Principal Investigator on the ARROW study, said: "The development of a RET-targeted therapy is a huge breakthrough in precision medicine for lung cancer. The approval of GAVRETO in China, greatly supported by the strong trial results from the ARROW study, may change standards of care for patients with RET fusion-positive NSCLC."

The ARROW study is a global phase I/II clinical study designed to evaluate the efficacy and safety of GAVRETO in patients with RET fusion-positive NSCLC, RET-mutant medullary thyroid cancer, and other advanced solid tumors with RET fusions. Data from the ARROW study showed that GAVRETO had robust and durable anti-tumor activity in Chinese patients with advanced or metastatic RET fusion-positive NSCLC after platinum-based chemotherapy. In these patients, the confirmed overall response rate was 56%, the median duration of response (DOR) was not reached, and the six-month DOR rate was 83%. GAVRETO was well-tolerated, and there were no adverse events related to treatment with GAVRETO that led to treatment discontinuation or death.

CStone has an exclusive collaboration and license agreement with Blueprint Medicines for the development and commercialization of pralsetinib in Greater China, which encompasses Mainland China, Hong Kong, Macau, and Taiwan.

About RET fusion-positive NSCLC

In recent years, China has had rising lung cancer incidence. In 2018, an estimated 770,000 new lung cancer cases and 690,000 new lung cancer deaths occurred in China. Among all Chinese cancer patients, lung cancer is the leading cause of cancer-related deaths. NSCLC is the most common type of lung cancer.

In lung cancer, there are a number of somatic mutations, including EGFR, ALK, and ROS1, that can be targeted with approved therapies. RET fusions account for 1-2% of NSCLC patients, the majority of whom are non-smokers.

About GAVRETO (pralsetinib)

GAVRETO (pralsetinib) is a once-daily oral targeted therapy approved by the NMPA of China for the treatment of adults with locally advanced or metastatic rearranged during transfection (RET) fusion-positive NSCLC after platinum-based chemotherapy.

GAVRETO has been approved by the U.S. Food and Drug Administration (FDA) for the treatment of adult patients with metastatic RET fusion-positive NSCLC as detected by an FDA approved test, adult and pediatric patients 12 years of age and older with advanced or metastatic RET-mutant medullary thyroid cancer (MTC), and adult and pediatric patients 12 years of age and older with advanced or metastatic RET fusion-positive thyroid cancer who require systemic therapy and who are radioactive iodine-refractory (if radioactive iodine is appropriate).

GAVRETO is not approved for the treatment of any other indication in China by the NMPA or in the U.S. by the FDA, or for any indication in any other jurisdiction by any other health authority.

GAVRETO is designed to selectively and potently target oncogenic RET alterations, including secondary RET mutations predicted to drive resistance to treatment. In preclinical studies, GAVRETO inhibited RET at lower concentrations than other pharmacologically relevant kinases, including VEGFR2, FGFR2, and JAK2.

Blueprint Medicines and Roche are co-developing GAVRETO globally (excluding Greater China) for the treatment of patients with RET-altered NSCLC, thyroid cancer, and other solid tumors. Blueprint Medicines and Genentech, a member of the Roche Group, are co-commercializing GAVRETO in the U.S., and Roche has exclusive commercialization rights for GAVRETO outside of the U.S. (excluding greater China). The European Medicines Agency validated a marketing authorization application for GAVRETO for the treatment of RET fusion-positive NSCLC, and the review is ongoing. The FDA granted breakthrough therapy designation to GAVRETO for the treatment of RET fusion-positive NSCLC that has progressed following platinum-based chemotherapy and for RET mutation-positive MTC that requires systemic treatment and for which there are no alternative treatments.
