KRAZATI (adagrasib) Demonstrated Statistically Significant Improvement in Progression-Free Survival in Patients with Pretreated Locally Advanced or Metastatic KRASG12C-Mutated Non-Small Cell Lung Cancer

First presentation of data from Phase 3 KRYSTAL-12 study showed statistically significant and clinically meaningful improvement in progression-free survival with KRAZATI compared to standard of care chemotherapy

Late-breaking data featured in an oral presentation at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting

Bristol Myers Squibb (NYSE: BMY) today announced results from the Phase 3 KRYSTAL-12 study evaluating KRAZATI^® (adagrasib) compared to standard of care chemotherapy in patients with locally advanced or metastatic KRAS^G12C-mutated non-small cell lung cancer (NSCLC) who had previously received platinum-based chemotherapy, concurrently or sequentially with anti-PD-(L)1 therapy. At a median follow-up of 9.4 months, KRAZATI demonstrated a statistically significant and clinically meaningful improvement in progression-free survival (PFS), the study’s primary endpoint, as assessed by Blinded Independent Central Review (BICR) compared to docetaxel (HR: 0.58; [95% CI, 0.45-0.76]; P <0.0001). Median PFS was 5.5 months for KRAZATI compared to 3.8 months for docetaxel. Overall response rate (ORR) as assessed by BICR was also significantly higher with KRAZATI compared to docetaxel (32% vs 9%; odds ratio, 4.68; P < 0.0001). The median duration of response (mDOR) was 8.31 months (95% CI, 6.05–10.35) versus 5.36 months (95% CI, 2.86–8.54), respectively.

KRAZATI demonstrated intracranial response among patients with central nervous system (CNS) metastases at baseline, with a response rate per BICR that was more than double that observed with docetaxel (24% with KRAZATI vs. 11% with docetaxel).

The KRYSTAL-12 study remains ongoing to assess the additional key secondary endpoint of overall survival.

No new safety signals were identified for KRAZATI, and the safety data were consistent with the known safety profile. Treatment-related adverse events (TRAEs) of any grade were reported in 94% of patients treated with KRAZATI and 86.4% with docetaxel. Grade ≥3 TRAEs occurred in 47% and 46% of patients, respectively.

These data will be presented in a late-breaking oral presentation during the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting on June 1 at 1:27 p.m. CDT (Abstract LBA8509).

“Approximately 14% of all patients with advanced non-small cell lung cancer carry the KRAS^G12C mutation, impacting thousands of people worldwide,” said Tony Mok, M.D., Chairman of the Department of Clinical Oncology and Li Shu Fan Medical Foundation Professor of Clinical Oncology of the Faculty of Medicine at The Chinese University of Hong Kong (CU Medicine). “These results from the Phase 3 KRYSTAL-12 study reinforce adagrasib as a targeted option for patients with KRAS^G12C-positive lung cancer after failing standard first-line treatment.”

“The accelerated approval of KRAZATI from the FDA in 2022 was welcome news for patients with KRAS^G12C-mutated locally advanced or metastatic NSCLC. These confirmatory results further support KRAZATI as an efficacious, targeted treatment option for these patients,” said Abderrahim Oukessou, M.D., vice president, global program lead, KRAZATI, Bristol Myers Squibb. “We look forward to further sharing these results, while also continuing to evaluate KRAZATI in other advanced KRAS^G12C-mutated solid tumors.”

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.

Bristol Myers Squibb thanks the patients and investigators involved in the KRYSTAL-12 clinical trial.

About KRYSTAL-12

KRYSTAL-12 is an open-label, multicenter, randomized Phase 3 study evaluating KRAZATI compared to standard-of-care chemotherapy alone, in patients with KRAS^G12C-mutated non-small cell lung cancer. The primary endpoint of the study is progression-free survival (PFS) as assessed by Blinded Independent Central Review (BICR). Secondary endpoints included overall survival (OS), overall response rate (ORR), duration of response (DOR), and safety.

About KRAS^G12C -Mutated Non-Small Cell Lung Cancer

Lung cancer is the leading cause of cancer deaths globally. The two main types of lung cancer are non-small cell and small cell. Non-small cell lung cancer (NSCLC) is one of the most common types of lung cancer, representing up to 84% of diagnoses. KRAS^G12C is the most common KRAS mutation in NSCLC, present in approximately 14% of patients with lung adenocarcinoma, and is a biomarker of poor prognosis.

About KRAZATI^® (adagrasib)

KRAZATI (adagrasib) is a highly selective and potent oral small-molecule inhibitor of KRAS^G12C that is optimized to sustain target inhibition, an attribute that could be important to treat KRAS^G12C-mutated cancers, as the KRAS^G12C protein regenerates every 24-48 hours. KRAS^G12C mutations act as oncogenic drivers and occur in approximately 14% of non-small cell lung cancer, 3-4% of colorectal cancer, and 1-2% of several other cancers.

In 2022, the U.S. Food and Drug Administration (FDA) granted KRAZATI accelerated approval for treatment of adult patients with KRAS^G12C-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).

KRAZATI continues to be evaluated as a monotherapy and in combination with other anti-cancer therapies in patients with advanced KRAS^G12C-mutated solid tumors, including NSCLC and colorectal cancer (CRC).
