Mirati Therapeutics To Present Preclinical Data From Investigational Pipeline Of Novel Therapeutics At 2020 American Association For Cancer Research Virtual Annual Meeting II

SAN DIEGO, May 15, 2020 /PRNewswire/ — Mirati Therapeutics, Inc. (NASDAQ: MRTX), a clinical-stage targeted oncology company, today announced it will present preclinical data on the Company’s pipeline of novel therapeutics in three presentations at the American Association for Cancer Research Virtual Annual Meeting II, taking place June 22-24, 2020. The data to be presented will include preclinical findings on MRTX849, a novel and optimized KRAS G12C inhibitor.

“We continue to develop an increasing understanding of the role of KRAS in the pathogenesis of cancers as well as the consequences of direct therapeutic inhibition of KRAS. We continue to aspire to apply these learnings toward rational drug development and to make a real and timely impact on patient lives,” said James G. Christensen, Ph.D. Executive Vice President and Chief Scientific Officer, Mirati Therapeutics.

About MRTX849

MRTX849 is an investigational, orally available small molecule that is designed to potently and selectively inhibit a form of KRAS which harbors a substitution mutation (G12C). KRAS G12C mutations are present in approximately 14% of non-small cell lung cancer adenocarcinoma patients, 4% of colorectal cancer patients, and subsets of other types of cancer. Tumors characterized by KRAS G12C mutations are commonly associated with poor prognosis and resistance to therapy, and patients with these mutations have few treatment options. MRTX849 is being evaluated in a Phase 1/2 trial treating patients with molecularly identified, KRAS G12C-positive advanced solid tumors.

About Mirati Therapeutics

Mirati Therapeutics (NASDAQ: MRTX) is a San Diego-based clinical-stage biotechnology company dedicated to advancing novel therapeutics that extend the lives of patients by directly addressing the genetic and immunological drivers of cancer. Mirati is developing sitravatinib, designed to selectively target a spectrum of tyrosine kinases implicated in both tumor growth and the suppression of immune responses to tumors. Sitravatinib has demonstrated durable responses in lung cancer patients whose cancer has progressed despite treatment with checkpoint inhibitors – an area of significant unmet medical need. Sitravatinib is being evaluated in multiple clinical trials to treat patients who are refractory to prior immune checkpoint inhibitor therapy, including a potentially registration-enabling Phase 3 trial of sitravatinib in combination with a checkpoint inhibitor in non-small cell lung cancer (NSCLC) that is currently enrolling patients.

Mirati is also developing novel inhibitors of KRAS mutations including MRTX849, a potent and selective inhibitor of KRAS G12C. This historically difficult to drug target is present in approximately 14% of NSCLC adenocarcinomas, 4% of colorectal cancer as well as smaller percentages of several other difficult-to-treat cancers. MRTX849 is being evaluated in a Phase 1/2 clinical trial as a treatment for patients with KRAS G12C-positive tumors. Our research on G12C has led to breakthroughs in targeting other KRAS mutations including G12D which drives tumor growth in more patients than G12C and includes pancreatic, colorectal and other types of cancer.
