• Shared plans to present preliminary safety and efficacy results from the KRYSTAL-7 study evaluating adagrasib in combination with pembrolizumab in patients with advanced NSCLC harboring a KRAS^G12C mutation at a medical meeting in December.

MRTX1719 (MTA cooperative PRMT5 inhibitor)

• In August 2022, the Food and Drug Administration (FDA) granted Fast Track designation to MRTX1719, an MTA cooperative PRMT5 inhibitor, in MTAP-deleted cancers. The Company is enrolling in an ongoing Phase 1/2 clinical trial in patients whose tumors harbor an MTAP deletion. The Company expects to share the initial clinical data for this program in 2023.

MRTX0902 (Potent SOS1 inhibitor)

• The Company plans to file an IND application for this program by year-end 2022.

• Announced the appointment of Alan Sandler, M.D., as CMO and the planned retirement of Charles Baum, M.D., Ph.D., president, founder and head of research and development in the second quarter of 2023. Dr. Baum remains on the Mirati board of directors. (View Release)

• Cash, cash equivalents, and short-term investments of approximately $1.2 billion as of September 30, 2022.
  
  
• Sold approximately 1.9 million shares of common stock under its At the Market Facility, which generated net proceeds of $155.0 million.
  
  
• Revenue for the third quarter of 2022 was $5.4 million, which was driven by the recognition of a $5 million milestone payment from Zai Lab that was contingent on starting a pivotal clinical study for adagrasib in a second indication in the Zai Lab designated territories. This compares to revenue of $71.8 million in third quarter of 2021, where we recognized $66.6 million of revenue associated with the transfer of the license and know-how of adagrasib as part of our agreement with Zai Lab, and a $5 million milestone payment from BeiGene, associated with the start of the first pivotal sitravatinib clinical study in the BeiGene designated territories.
  
  
• Research and development expenses for the third quarter of 2022 were $131.1 million, compared to $116.1 million for the same period in 2021. Research and development expenses for the nine months ended September 30, 2022 were $390.4 million, compared to $354.8 million for the same periods in 2021. The increases were primarily related to an increase in headcount-related costs, including share-based compensation and salaries, due to the growth of our portfolio, offset by a decrease in manufacturing costs that occurred after our 2021 NDA filing for the adagrasib program. The Company recognized research and development-related share-based compensation expenses of $28.3 million during the third quarter of 2022, compared to $15.7 million for the same period in 2021, and $77.3 million during the nine months ended September 30, 2022, compared to $46.7 million for the same period in 2021.
  
  
• General and administrative expenses for the third quarter of 2022 were $60.8 million, compared to $35.2 million for the same period in 2021. General and administrative expenses for the nine months ended September 30, 2022 were $169.0 million, compared to $93.1 million for the same period in 2021. The increases were primarily due to an increase in commercial readiness costs, including increases in headcount-related costs, as we prepare for a potential product launch. The Company recognized general and administrative-related share-based compensation expenses of $14.7 million in the third quarter of 2022, compared to $11.2 million for the same period in 2021, and $47.2 million during the nine months ended September 30, 2022, compared to $32.9 million for the same period in 2021.
  
  
• Net loss for the third quarter of 2022 was $173.6 million, or $3.09 per share basic and diluted, compared to a net loss of $80.1 million, or $1.55 per share basic and diluted for the same period in 2021. Net loss for the nine months ended September 30, 2022 was $538.4 million, or $9.66 per share basic and diluted, compared to a net loss of $382.2 million, or $7.45 per share basic and diluted for the same period in 2021.
