SAN DIEGO, Aug. 8, 2023 /PRNewswire/ -- Mirati Therapeutics, Inc.® (NASDAQ: MRTX), a commercial stage biotechnology company, today announced financial results for the second quarter 2023 along with recent pipeline and corporate updates.

"We are pleased to share the significant progress made during the second quarter of 2023, highlighted by an update to the clinical data and articulation of our path to develop KRAZATI® in front line non-small cell lung cancer (NSCLC). Coupled with strong second quarter KRAZATI sales performance, these data reinforce our belief that KRAZATI is the best-in-class KRASG12C inhibitor with significant potential to positively impact the lives of patients living with cancer," said Charles Baum, M.D, Ph.D., interim CEO, president and founder, Mirati Therapeutics, Inc. "Further, we advanced our robust pipeline of targeted oncology programs, including MRTX1719, our potentially first-in-class MTA cooperative PRMT5 inhibitor, where we demonstrated a favorable safety profile, proof of mechanism and compelling early clinical activity in patients with MTAP-deleted cancers. Looking ahead, we are confident in the potential of our broad pipeline of innovative, potentially best-in-class programs including MRTX1133 and our next generation of KRAS inhibitors, as well as MRTX1719 and MRTX0902, our SOS1 inhibitor.  We continue to demonstrate our proven expertise in the discovery and development of transformational treatments for people living with cancer."

Pipeline Updates

Adagrasib (Potent and selective KRASG12C inhibitor)

  • In August, the Company shared updated clinical data in first-line NSCLC for the combination of adagrasib with pembrolizumab. The Company announced plans to begin enrolling patients with TPS ≥ 50% in a Phase 3 clinical study by year-end 2023.
  • In August, the Company shared that KRYSTAL 17, a Phase 2 clinical study evaluating adagrasib in combination with chemo-immunotherapy for patients with TPS < 50% has been initiated.

The evaluation of the full MAA is not impacted and will be considered by the CHMP following the data from KRYSTAL-12, a Phase 3 clinical study of adagrasib versus docetaxel in second line NSCLC patients. The Company has requested a formal reexamination of the Conditional MAA. (View Release)
  • In June, the Journal of Clinical Oncology published clinical results from the KRYSTAL-1 study of adagrasib, a potent and selective KRASG12C inhibitor, demonstrating durable intracranial activity in patients living with KRASG12C-mutated NSCLC with untreated central nervous system metastases.

Second Quarter Financial Results

  • Cash, cash equivalents and short-term investments of approximately $779.4 million as of June 30, 2023. Net reduction in cash, cash equivalents and short-term investments for the second quarter of 2023 was $122.9 million. The Company expects 2023 net cash burn to annualize within a range of $560 million to $580 million.
  • Net KRAZATI® product revenue for the three and six months ended June 30, 2023 was $13.4 million and $19.7 million, respectively. Net product revenue during the three months ended June 30, 2023 was comprised of $11.7 million of commercial sales and $1.7 million of sales to a third-party commercial customer for its clinical trials. There was no product revenue for the same periods in 2022.
  • License and collaboration revenue for the three and six months ended June 30, 2023 was $0.3 million and $1.2 million, respectively, related to clinical supply revenue earned under the agreement with Zai Lab. License and collaboration revenue for the same periods in 2022 was $5.4 million and $6.1 million, respectively, related to a $5 million milestone payment from Zai Lab for the initiation of the first pivotal clinical trial of adagrasib for the first indication in China, and clinical supply revenue earned under the agreement with Zai Lab.
  • Cost of product revenue for the three and six months ended June 30, 2023 was $1.3 million and $2.1 million, respectively, of which $1.0 million and $1.6 million, respectively, related to product manufacturing and distribution costs, and royalties incurred on net sales of KRAZATI®, and the remainder represented non-cash amortization expense for our intangible asset. There was no cost of product revenue for the same periods in 2022.
  • Research and development expenses for three and six months ended June 30, 2023 were $124.2 million and $250.9 million, respectively, compared to $128.3 million and $259.3 million for the same periods in 2022, respectively. The decrease was primarily driven by a reduction in clinical development costs for sitravatinib as enrollment was completed in the SAPPHIRE Phase 3 clinical study in the second quarter of 2022, and a decrease in share-based compensation due to a decrease in the fair value of equity awards granted during the period, partially offset by increases in costs for earlier stage clinical development programs such as MRTX1133, and an increase in salaries and other employee related expense to support portfolio advancement.
  • Selling, general and administrative expenses for the three and six months ended June 30, 2023 were $75.5 million and $149.0 million, respectively, compared to $54.2 million and $108.2 million, respectively for the same periods in 2022. The increases were primarily due to an increase in headcount-related costs, including share-based compensation and salaries, and commercial-related costs to support the marketing and sales of KRAZATI®.
  • Net loss for the three months ended June 30, 2023 was $176.9 million, or $3.04 per share basic and diluted, compared to a net loss of $176.4 million, or $3.18 per share basic and diluted for the same period in 2022. Net loss for the six months ended June 30, 2023 was $361.5 million, or $6.22 per share basic and diluted, compared to a net loss of $364.8 million, or $6.57 per share basic and diluted for the same period in 2022.
