Pipeline Updates

Adagrasib (Potent and selective KRAS^G12C inhibitor)

• In December 2022, the Company announced the U.S. Food and Drug Administration (FDA) granted accelerated approval of KRAZATI™ (adagrasib), a targeted treatment option for adult patients with KRAS^G12C-mutated locally advanced or metastatic NSCLC who have received at least one prior systemic therapy. (View Release)
• In December 2022, the Company announced the FDA granted Breakthrough Therapy Designation (BTD) for adagrasib in combination with cetuximab in patients with KRAS^G12C-mutated advanced colorectal cancer (CRC) whose cancer has progressed following prior treatment with chemotherapy and an anti-VEGF therapy. The New England Journal of Medicine published these findings, which demonstrate promising clinical activity and a favorable tolerability profile. Based on recent FDA discussions, the Company expects to move forward with an application for Accelerated Approval in third-line or later KRAS^G12C-mutated advanced CRC. (View Release)
• In December 2022, the Company announced preliminary results from the KRYSTAL-7 Phase 2 study and KRYSTAL-1 Phase 1b cohort evaluating adagrasib concurrently combined with pembrolizumab in patients for the treatment of first-line NSCLC harboring a KRAS^G12C mutation at the 2022 European Society for Medical Oncology (ESMO) Immuno-Oncology Annual Congress. The data demonstrated the combinability of KRAZATI™ with pembrolizumab as well as initial promising clinical activity. (View Release)

Fourth Quarter and Full-Year 2022 Financial Results

• Cash, cash equivalents, and short-term investments of approximately $1.1 billion as of December 31, 2022.
• Net product revenue for both the fourth quarter 2022 and the twelve months ended December 31, 2022 was $0.7 million and was driven by sales of KRAZATI^TM, which received approval by the FDA and launched commercially in the U.S. in December 2022. There was no product revenue for the same periods in 2021.
• License and collaboration revenue for the fourth quarter 2022 was $0.2 million, compared to $0.3 million for the same period in 2021. License and collaboration revenues for the twelve months ended December 31, 2022 were $11.7 million, primarily driven by milestone payments received from Zai Lab in connection with the initiation of pivotal clinical studies of adagrasib for the first and second indications in the Zai Lab designated territories during 2022. This compares to license and collaboration revenues of $72.1 million for the same period in 2021, primarily driven by $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 $5.0 million milestone payment from BeiGene, associated with the start of the first pivotal sitravatinib clinical study in the BeiGene designated territories.
• Cost of product revenue for both the fourth quarter 2022 and the twelve months ended December 31, 2022 was $0.6 million and was primarily due to non-recurring, launch-related product distribution costs for KRAZATI^TM following FDA approval in December 2022. There was no cost of product revenue for the same periods in 2021.
• Research and development expenses for the fourth quarter 2022 were $141.2 million, compared to $153.8 million for the same period in 2021. Research and development expenses for the twelve months ended December 31, 2022 were $531.6 million, compared to $508.6 million for the same period in 2021. The decrease in research and development expenses for the fourth quarter 2022 compared to same period in 2021 was primarily due to the manufacturing costs incurred in 2021 to support our New Drug Application (NDA) and commercial launch, partially offset by an increase in headcount-related costs, including share-based compensation and salaries, due to the growth of our headcount to support our growing portfolio. The increase in research and development expenses for the twelve months ended December 31, 2022 compared to same period in 2021 was primarily driven by an increase in development costs to advance our preclinical and clinical development programs, and an increase headcount-related costs, including share-based compensation and salaries, offset primarily by a reduction in manufacturing costs for adagrasib to support our NDA and commercial launch. The Company recognized research and development-related share-based compensation expenses of $36.2 million during the fourth quarter 2022, compared to $21.8 million for the same period in 2021, and $113.5 million during the twelve months ended December 31, 2022, compared to $68.5 million for the same period in 2021.
• Selling, general and administrative expenses for the fourth quarter 2022 were $70.8 million, compared to $43.5 million for the same period in 2021. Selling, general and administrative expenses for the twelve months ended December 31, 2022 were $239.8 million, compared to $136.7 million for the same period in 2021. The increases were primarily due to an increase in headcount-related costs, including share-based compensation and salaries, and commercial readiness costs as we prepared for the commercial launch of KRAZATI^TM. The Company recognized selling, general and administrative-related share-based compensation expenses of $25.4 million in the fourth quarter 2022, compared to $12.1 million for the same period in 2021, and $72.6 million during the twelve months ended December 31, 2022, compared to $45.0 million for the same period in 2021.
• Net loss for the fourth quarter 2022 was $202.5 million, or $3.51 per share basic and diluted, compared to a net loss of $199.6 million, or $3.72 per share basic and diluted for the same period in 2021. Net loss for the twelve months ended December 31, 2022 was $740.9 million, or $13.18 per share basic and diluted, compared to a net loss of $581.8 million, or $11.21 per share basic and diluted for the same period in 2021.
