SAN DIEGO, CA, USA I December 12, 2022 I Mirati Therapeutics, Inc. (NASDAQ: MRTX), a targeted oncology company, today announced that the U.S. Food and Drug Administration (FDA) has granted accelerated approval for KRAZATI™ (adagrasib), a targeted treatment option for adult patients with KRASG12C-mutated locally advanced or metastatic non-small cell lung cancer (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).

“The FDA approval of KRAZATI is a positive development for thousands of patients with KRASG12C mutations, including the approximately 14% of patients with NSCLC adenocarcinomas histology that harbor a KRASG12C mutation.1 Mirati is thrilled to make KRAZATI available in a tablet formulation to patients in the U.S. with advanced NSCLC who have progressed beyond a first-line treatment for the historically difficult-to-treat KRAS mutation,” David Meek, chief executive officer, Mirati Therapeutics, Inc., continued, “We look forward to continuing to advance our KRAZATI development program including several monotherapy and combination studies in KRASG12C-mutated solid tumors.”
KRAZATI has demonstrated a positive benefit-risk profile with accelerated approval based on the Phase 2 registration-enabling cohort of the KRYSTAL-1 study, evaluating KRAZATI 600 mg capsules administered orally twice daily in 116 patients with KRASG12C-mutated advanced NSCLC who previously received treatment with a platinum-based regimen and an immune checkpoint inhibitor. The primary efficacy endpoints were confirmed ORR and DOR as evaluated by blinded independent central review (BICR) according to response evaluation criteria in solid tumors (RECIST v1.1).
The trial demonstrated an ORR of 43% (95% CI: 34-53) with 80% (95% CI: 71-87) of patients achieving disease control. The median DOR was 8.5 months (95% CI: 6.2-13.8).
In a pooled efficacy analysis (n=132) including Phase 1/1b NSCLC and registrational Phase 2 NSCLC cohorts from the KRYSTAL-1 study evaluating adagrasib as a single agent at 600 mg capsules orally twice daily, adagrasib showed an ORR of 44% and a disease control rate of 81% based on BICR, a median DOR of 12.5 months (95% CI, 7.3-NE) and median overall survival of 14.1 months (94% CI, 9.2-19.2).
The safety profile of KRAZATI was evaluated in a pooled patient population with NSCLC and other solid tumors as a single agent at 600 mg orally twice daily in 366 patients enrolled in KRYSTAL-1 and KRYSTAL-12. The most common (≥ 25%) adverse reactions were nausea, diarrhea, vomiting, fatigue, musculoskeletal pain, hepatotoxicity, renal impairment, edema, dyspnea and decreased appetite. Permanent discontinuation of KRAZATI due to an adverse reaction occurred in 13% of patients.
Although KRASG12C is the most common KRAS mutation in NSCLC, patients have had limited options for the treatment of this debilitating and difficult-to-treat condition.2,3
“The approval of KRAZATI offers an effective therapy for patients with advanced NSCLC harboring the KRASG12C mutation. The positive ORR and DOR results, as observed in previously treated patients with NSCLC harboring the KRASG12C mutation, demonstrate the effectiveness of KRAZATI as an option for these difficult-to-treat patients,” said Shirish M. Gadgeel, MD, chief of the Division of Hematology and Oncology, Department of Internal Medicine, Henry Ford Cancer Institute/Henry Ford Health System.
“KRASG12C in NSCLC is an area of high unmet need and new treatment options offer patients and our community new hope for survivorship,” said Bonnie J. Addario, co-founder and board chair of the GO2 Foundation for Lung Cancer. “I’m pleased that patients have options, there’s more awareness of this disease and we are all focused on improving the journeys of people living with KRASG12C-mutated NSCLC.”
The Company partnered with Agilent and QIAGEN to develop blood- and tissue-based companion diagnostics (CDx), respectively, for KRAZATI that are now available. With tissue and blood modalities for companion diagnostics, patients have more flexibility, and clinicians have greater options for biomarker testing. These solutions help to personalize a patient’s treatment path.

About KRAZATI (adagrasib)
Mirati has risen to meet one of the most challenging mutations in cancer research by developing KRAZATI, a highly selective and potent oral small-molecule inhibitor of KRASG12C.
Intentionally designed to meet the challenge of KRASG12C, adagrasib is optimized to sustain target inhibition, an attribute that could be important to treat KRASG12C-mutated cancers, as the KRASG12C protein regenerates every 24−48 hours.4 Adagrasib has shown clinically to be a CNS penetrant, which may be important given that CNS metastases frequently occur in NSCLC and lead to poor prognosis.5,6,7
In the U.S., KRAZATI was reviewed by the FDA for Accelerated Approval (Subpart H), which allows for the approval of drugs that treat serious conditions, and that fill an unmet medical need based on surrogate endpoints. KRAZATI was reviewed under the FDA Real-Time Oncology Review (RTOR) pilot program, which aims to explore a more efficient review process that ensures safe and effective treatments are made available to patients as early as possible. Mirati submitted a Marketing Authorization Application (MAA) in the EU in May 2022. In 2021, adagrasib achieved Breakthrough Therapy Designation in the U.S. as a potential treatment for patients with NSCLC harboring the KRASG12C mutation who have received at least one prior systemic therapy.
Adagrasib continues to be evaluated as monotherapy and in combination with other anti-cancer therapies in patients with advanced KRASG12C-mutated solid tumors, including NSCLC, colorectal cancer, and pancreatic cancer. For more information, visit Mirati.com/science.
Mirati has an Expanded Access Program (EAP) for adagrasib for the treatment of eligible patients with KRASG12C-mutated cancers, regardless of tumor type, including patients with treated or untreated CNS metastases, in the U.S. Learn more about the EAP at Mirati.com/expanded-access-policy.
KRAZATI (adagrasib) U.S. Indication
KRAZATI is indicated for the treatment of adult patients with KRASG12C-mutated locally advanced or metastatic non-small cell lung cancer (NSCLC), as determined by an FDA-approved test, who have received at least one prior systemic therapy.

About the KRYSTAL-1 Study
KRYSTAL-1 is an open-label Phase 1/2 multiple-expansion cohort trial evaluating adagrasib as monotherapy and in combination with other anti-cancer therapies in patients with advanced solid tumors harboring the KRASG12C mutation.
About KRASG12C in NSCLC
Lung cancer is one of the most common cancers worldwide, accounting for 2.21 million new cases and 1.8 million deaths worldwide in 2020.8 Lung cancer consists of NSCLC in approximately 85% of cases and small cell lung cancer (SCLC) in approximately 15% of cases.9 KRASG12C is the most common KRAS mutation in NSCLC, present in approximately 14% of patients with lung adenocarcinoma, and is a biomarker mutation of poor prognosis.1,3
