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 KRASG12C-Mutated Locally Advanced or Metastatic...
- Positive results from the KRYSTAL-12 confirmatory trial showcase the efficacy of adagrasib in treating KRASG12C-mutated NSCLC patients.
- Adagrasib met the primary endpoint of progression-free survival and key secondary endpoint of overall response rate in the Phase 3 study.
- The safety profile of KRAZATI remains consistent with known safety data, with no new safety signals reported.
- Zai Lab plans to submit the New Drug Application for adagrasib to the NMPA in China for KRASG12C-mutated NSCLC later this year.
- KRAZATI has shown promising benefits in Phase 2 trials for various tumors, including colorectal cancer and pancreatic cancer.
- The FDA accepted the sNDA for KRAZATI in combination with cetuximab for KRASG12C-mutated CRC, with a PDUFA goal date set for June 21, 2024.
- None.
The recent findings from the KRYSTAL-12 study are a promising advancement in the treatment of non-small cell lung cancer (NSCLC) with a specific mutation known as KRASG12C. As an oncologist, the improvement in progression-free survival (PFS) and overall response rate (ORR) observed with KRAZATI (adagrasib) is noteworthy. These metrics are critical in assessing how effectively a cancer treatment can delay the disease's progression and reduce tumor burden without the disease worsening.
Furthermore, the absence of new safety signals reinforces the medication's tolerability, an essential factor in patient care. The continuation of the study to evaluate overall survival is crucial, as it will provide insights into the potential for not just living longer but also better quality of life. The success of adagrasib in NSCLC could lead to its application in other cancers with the same mutation, which is an exciting prospect for oncology therapeutics.
From a market perspective, the positive results from the KRYSTAL-12 trial could significantly impact Zai Lab and Bristol Myers Squibb's market positioning. NSCLC is a high-incidence cancer, particularly in China, which represents a substantial market opportunity for Zai Lab. The successful trial outcomes and the subsequent New Drug Application (NDA) in China could catalyze Zai Lab's market growth and strengthen its oncology pipeline.
Investors should note the potential for increased market share in the NSCLC treatment space, especially since KRAZATI targets a specific mutation that may not be addressed by many existing therapies. Moreover, the priority review status granted by the FDA for KRAZATI in colorectal cancer underscores the drug's significance and could expedite its availability, further enhancing the company's competitive edge.
For investors, the announcement of a trial meeting its primary endpoint typically signals potential future revenue growth, especially for treatments in high-demand areas like NSCLC. The consistency of KRAZATI's safety profile and its efficacy beyond first-line treatments could lead to strong adoption rates once approved. It's also important to consider the broader financial implications, such as the impact of the upcoming Prescription Drug User Fee Act (PDUFA) goal date on the stock's volatility.
Investors should watch for the NDA submission in China, as approval in this large market could provide a significant revenue stream for Zai Lab. However, the long-term financial impact will depend on the overall survival data, market penetration rates and competitive dynamics, including the introduction of other targeted therapies and generics.
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 KRASG12C-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 KRASG12C 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 KRASG12C 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
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 KRASG12C mutated NSCLC in second or later line treatment in
In addition to KRASG12C-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
Zai Lab thanks the patients and investigators involved in the KRYSTAL-12 clinical trial.

ABOUT KRAZATI® (adagrasib)
KRAZATI (adagrasib) is highly selective and potent oral small-molecule inhibitor of KRASG12C that is optimized to sustain target inhibition, an attribute that could be important to treat KRASG12C-mutated cancers, as the KRAS protein regenerates every 24-48 hours. In
In 2022, KRAZATI was granted accelerated approval for treatment of adult patients with KRASG12C-mutated locally advanced or metastatic NSCLC, as determined by an FDA-approved test, who have received at least one prior systemic therapy. This indication is approved under accelerated approval based on objective response rate (ORR) and duration of response (DOR). Continued approval for this indication may be contingent upon verification and description of a clinical benefit in a confirmatory trial(s).
In 2023, Medicines and Healthcare products Regulatory Agency (MHRA) granted conditional marketing authorization for KRAZATI as a targeted treatment option for adult patients with KRASG12C-mutated advanced non-small cell lung cancer and disease progression after at least one prior systemic therapy followed by the European Commission (EC) in 2024.
KRAZATI continues to be evaluated as monotherapy and in combination with other anti-cancer therapies in patients with advanced KRASG12C-mutated solid tumors, including non-small cell lung cancer and colorectal cancer.
In 2022, the FDA granted breakthrough therapy designation for KRAZATI in combination with cetuximab in patients with KRASG12C-mutated advanced colorectal cancer whose cancer has progressed following prior treatment with chemotherapy and an anti-VEGF therapy.
