Mirati Therapeutics Reports Third Quarter Financial Results


SAN DIEGO, Nov. 6, 2018 /PRNewswire/ -- Mirati Therapeutics, Inc. (NASDAQ: MRTX), a clinical-stage targeted oncology company, today reported financial results for the third quarter ended September 30, 2018.

"We are pleased that our sitravatinib and MRTX849 (KRAS) programs are advancing into the next stages of development. We expect to enroll the first patient in our much-anticipated Phase 1 trial for MRTX849 in January 2019 and we plan to begin a Phase 3 randomized trial with sitravatinib in combination with a checkpoint inhibitor in the first half of 2019," said Charles M. Baum, M.D., Ph.D., President and Chief Executive Officer. "We remain well funded to execute our plans with over $240 million of cash and investments at the end of the third quarter."

Financial Results for the Third Quarter 2018

Cash, cash equivalents, and short-term investments were $242.6 million at September 30, 2018, compared to $150.8 million at December 31, 2017.  In June 2018, we completed a public equity offering with net proceeds of $130.7 million.

License and collaboration revenues for the nine months ended September 30, 2018 were $9.5 million, compared to none in the same period of 2017.  License and collaboration revenues relate to the Collaboration and License Agreement between the Company and BeiGene, Ltd., which became effective January 7, 2018. 

Research and development expenses for the third quarter of 2018 were $23.6 million, compared to $13.5 million for the same period in 2017. Research and development expenses for the nine months ended September 30, 2018 were $67.1 million compared to $42.8 million for the same period in 2017.  The increase in research and development expenses for both the three and nine months ended September 30, 2018 is due to an increase in third party research and development expense for sitravatinib and our KRAS inhibitor program.  The increase in sitravatinib expense is due to the expansion of ongoing clinical trials and the increase in KRAS inhibitor program expense relates to costs associated with our recently filed IND application for our lead clinical compound, MRTX849. The increase is also related to increased salaries and related expense, including an increase in share-based compensation expense due to an increase in the fair value of stock options granted.

General and administrative expenses for the third quarter of 2018 were $5.3 million, compared to $3.1 million for the same period in 2017.   General and administrative expenses for the nine months ended September 30, 2018 were $15.3 million compared to $10.5 million for the same period of 2017.  The increase for both the three and nine months ended September 30, 2018 is primarily due to an increase in share-based compensation expense due to an increase in the fair value of stock options granted, as well as an increase in professional and consulting fees.

Net loss for the third quarter of 2018 was $27.6 million, or $0.85 per share basic and diluted, compared to net loss of $16.4 million, or $0.65 per share basic and diluted for the same period in 2017.  Net loss for the nine months ended September 30, 2018 was $70.1 million, or $2.31 per share, compared to $52.5 million, or $2.12 per share, for the same period of 2017.

About MRTX849

MRTX849 is an orally-available small molecule that potently and selectively inhibits a form of KRAS which harbors a substitution mutation (G12C). KRAS G12C mutations are present in approximately 14% of NSCLC adenocarcinoma patients and 5% of colorectal cancer patients. 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. MTRX849 has demonstrated broad-spectrum tumor regression in a large cohort of KRAS G12C positive, pre-clinical in-vivo human tumor models. MRTX849 demonstrated complete regression of tumors in a subset of models at well-tolerated dose levels. Early proof-of-concept clinical data is anticipated in 2019.

About Sitravatinib

Sitravatinib is a spectrum-selective kinase inhibitor that potently inhibits receptor tyrosine kinases (RTKs), including TAM family receptors (TYRO3, Axl, Mer), split family receptors (VEGFR2, KIT) and RET. As an immuno-oncology agent, sitravatinib is being evaluated in combination with nivolumab (OPDIVO®), an anti-PD-1 checkpoint inhibitor, in patients who have experienced documented disease progression following treatment with a checkpoint inhibitor. Sitravatinib's potent inhibition of TAM and split family RTKs may overcome resistance to checkpoint inhibitor therapy through targeted reversal of an immunosuppressive tumor microenvironment, enhancing antigen-specific T cell response and expanding dendritic cell-dependent antigen presentation.

Sitravatinib is also being evaluated as a single agent in a Phase 1b expansion clinical trial enrolling patients whose tumors harbor specific mutations in the CBL protein. When CBL is inactivated by mutation, multiple RTKs, including TAM, VEGFR2 and KIT, are dysregulated and may act as oncogenic tumor drivers in NSCLC and melanoma. Sitravatinib potently inhibits these RTKs and is being investigated as a treatment option for cancer patients with CBL mutations.

About Mirati Therapeutics

Mirati Therapeutics, Inc. is a clinical-stage oncology company developing product candidates to address the genetic, epigenetic and immunological promoters of cancer. Our precision oncology clinical programs utilize next-generation genomic testing to identify and select cancer patients who we believe would be most likely to benefit from targeted drug treatment. In immuno-oncology, we are advancing clinical programs where our product candidates have the potential to improve the immune environment of tumor cells and may enhance and expand the efficacy of existing cancer immunotherapy medicines when given in combination. Our pre-clinical programs include potentially first-in-class and best-in-class product candidates specifically designed to address mutations and tumors where few treatment options exist. We approach each of our discovery and development programs with a singular focus: to translate our deep understanding of the molecular drivers of cancer into better therapies and better outcomes for patients.
