Zai Lab Partner Bristol Myers Squibb Announces Pivotal KRYSTAL-12 Confirmatory Trial Evaluating KRAZATI (adagrasib) Meets Primary Endpoint of Progression-Free Survival for Patients with Pretreated KRAS^G12C-Mutated Locally Advanced or Metastatic Non-Small Cell Lung Cancer

 

Zai Lab Limited (NASDAQ: ZLAB; HKEX: 9688) partner Bristol Myers Squibb (NYSE: BMY) announced the pivotal Phase 3 KRYSTAL-12 study, evaluating KRAZATI (adagrasib) as a monotherapy in patients with pretreated locally advanced or metastatic non-small cell lung cancer (NSCLC) harboring a KRAS^G12C mutation, met the primary endpoint of progression-free survival (PFS) and the key secondary endpoint of overall response rate (ORR) as assessed by Blinded Independent Central Review (BICR) at final analysis for these endpoints. The study remains ongoing to assess the additional key secondary endpoint of overall survival. Results of the confirmatory trial showed that KRAZATI demonstrated a statistically significant and clinically meaningful benefit in PFS and ORR compared to standard-of-care chemotherapy as a second-line or later treatment for these patients. KRAZATI had no new safety signals and the safety data was consistent with the known safety profile.

“We are delighted to see these data underscoring the potential of adagrasib as a therapy for patients with KRAS^G12C mutated NSCLC in second or later line treatment,” said Rafael G. Amado, M.D., President, Head of Global Oncology Research and Development, Zai Lab. “Lung cancer is the most common cancer in China, and adagrasib is one of several important products in Zai Lab’s growing lung cancer pipeline. We are proud to have contributed to the KRYSTAL-12 study and are looking forward to bringing adagrasib to patients in need in China."

Bristol Myers Squibb will complete a full evaluation of the available data and will share the results with the scientific community at an upcoming medical conference as well as discuss the results with health authorities.

Zai Lab expects to submit the New Drug Application (NDA) for adagrasib to the National Medical Products Association (NMPA) for KRAS^G12C mutated NSCLC in second or later line treatment in China this year.

In addition to KRAS^G12C-mutated NSCLC, KRAZATI and KRAZATI-based combinations have shown encouraging meaningful benefit in Phase 2 clinical trials across several tumors, including advanced colorectal cancer, pancreatic cancer and other solid tumors. In February, the U.S. FDA accepted for priority review the supplemental new drug application (sNDA) for KRAZATI in combination with cetuximab for the treatment of patients with previously treated KRAS^G12C-mutated locally advanced or metastatic colorectal cancer (CRC). The FDA assigned a Prescription Drug User Fee Act (PDUFA) goal date of June 21, 2024.
