SAN DIEGO, Aug. 5, 2021 /PRNewswire/ -- Mirati Therapeutics, Inc. (NASDAQ: MRTX), a clinical-stage targeted oncology company, today reported financial results for the second quarter of 2021 and recent corporate updates.
"We continue to aggressively advance our clinical and growing preclinical pipeline of oncology programs," said Charles M. Baum, M.D., Ph.D., president and chief executive officer, Mirati Therapeutics, Inc. "We achieved breakthrough therapy designation for adagrasib, and look forward to submitting the new drug application this year with the goal of extending and improving the lives of patients with non-small cell lung cancer who have a KRASG12C mutation."
"In addition, the sitravatinib registration trial in non-squamous non-small cell lung cancer is on track to read out an interim analysis of overall survival in the second half of 2022. Our potentially first-in-class preclinical programs in IND-enabling studies include KRASG12D inhibitor, MRTX1133, as well as a synthetic lethal PRMT5 inhibitor, MRTX1719, for which we expect to file an IND application by the end of 2021."
Announced the U.S. Food and Drug Administration (FDA) granted Breakthrough Therapy Designation to adagrasib. (View Release). The Company plans to present updated non-small cell lung cancer (NSCLC) data in the second half of 2021 and submit a New Drug Application (NDA) for adagrasib in the fourth quarter of 2021 for the potential treatment of patients with NSCLC who harbor the KRASG12C mutation following prior systemic therapy.
Plan to present new colorectal cancer (CRC) data at a medical conference in the second half of 2021 from the Phase 1/2 KRYSTAL-01 study evaluating adagrasib in combination with cetuximab1 (ERBITUX®) in second-line patients with a KRASG12C mutation and as a monotherapy in patients who have received three or more lines of therapy.
Initiated KRYSTAL-014, a Phase 1/1b study evaluating the combination of adagrasib with Boehringer Ingelheim's SOS1 inhibitor (BI 1701963) in patients with solid tumors that harbor the KRASG12C mutation.
Announced the Company entered into a collaboration and license agreement with Zai Lab for adagrasib in Greater China. (View Release)
Announced updated data will be presented at the 2021 European Society for Medical Oncology (ESMO) congress from the Phase 2 MRTX-500 study evaluating sitravatinib plus nivolumab (OPDIVO®)2 in patients with advanced NSCLC who had documented progression following treatment with checkpoint inhibitor therapy.
Plan to provide an update, based on an interim analysis of overall survival, from the Phase 3 SAPPHIRE study evaluating sitravatinib plus nivolumab in second or third line non-squamous NSCLC in the second half of 2022; enrollment is ongoing.
Announced selection of clinical development candidate, MRTX1719, for investigational synthetic lethal MTA cooperative PRMT5 inhibitor in methylthioadenosine phosphorylase (MTAP)-deleted cancers. The Company expects to file an Investigational New Drug (IND) application for MRTX1719 by the end of 2021.
Announced the Company has an in-house discovery program targeting SOS1 in lead candidate optimization stage leveraging the target's utility as a KRAS signaling modifier as a monotherapy or in combination with KRAS inhibitors.
Second Quarter 2021 Financial Results
Ended the second quarter with approximately $1.2 billion in cash, cash equivalents, and short-term investments, which does not include the upfront fee of $65 million from Zai Lab pursuant to the collaboration and license agreement executed during the quarter.
Research and development expenses for the second quarter of 2021 were $134.6 million, compared to $65.1 million for the same period in 2020. Research and development expenses for the six months ended June 30, 2021 were $238.6 million, compared to $136.8 million for the same period in 2020. The increase in research and development expenses is primarily due to an increase in expense associated with the development of adagrasib, an increase in preclinical and early discovery activities, as well as an increase in salaries and other employee-related expense, which includes an increase in share-based compensation expense. The Company recognized research and development-related share-based compensation expenses of $16.5 million during the second quarter of 2021, compared to $11.5 million for the same period in 2020, and $31.0 million during the six months ended June 30, 2021, compared to $23.3 million for the same period in 2020.
General and administrative expenses for the second quarter of 2021 were $29.6 million, compared to $19.8 million for the same period in 2020. General and administrative expenses for the six months ended June 30, 2021 were $58.0 million, compared to $37.8 million for the same period in 2020. The increase is primarily due to an increase in salaries and other employee-related expenses, an increase in insurance, rent and other facilities-related costs, and an increase in sponsorship agreements expense, and an increase in professional service expense. The Company recognized general and administrative-related share-based compensation expenses of $11.5 million in the second quarter of 2021, compared to $9.3 million for the same period in 2020, and $21.7 million during the six months ended June 30, 2021, compared to $19.0 million for the same period in 2020.
Net loss for the second quarter of 2021 was $166.4 million, or $3.23 per share basic and diluted, compared to a net loss of $82.9 million, or $1.89 per share basic and diluted for the same period in 2020. Net loss for the six months ended June 30, 2021 was $302.1 million, or $5.91 per share basic and diluted, compared to a net loss of $169.5 million, or $3.91 per share basic and diluted for the same period in 2020.
