IDEAYA Biosciences, Inc. Reports First Quarter 2025 Financial Results and Provides Business Update
SOUTH SAN FRANCISCO, Calif., May 6, 2025 -- IDEAYA Biosciences, Inc. (Nasdaq: IDYA), a precision medicine oncology company committed to the discovery and development of targeted therapeutics, provided a business update and announced financial results for the first quarter that ended March 31, 2025.
"We have provided an updated cash runway guidance into 2029, and this past quarter we made significant progress on the darovasertib program, including receiving U.S. FDA breakthrough therapy designation, and enrollment is ahead of schedule with over 300 patients in the 1L HLA-A2-negative MUM registrational trial for a targeted median PFS readout by year-end to enable a potential accelerated approval filing next year. We also advanced a broad clinical pipeline of potential first-in-class programs to continue to drive forward our growth strategy, including DLL3 TOP1 ADC IDE849 in lung cancer, Werner Helicase inhibitor IDE275 in MSI-high colorectal and endometrial cancer, and MAT2A inhibitor IDE397 in MTAP-deletion lung and urothelial cancer," said Yujiro S. Hata, President and Chief Executive Officer, IDEAYA Biosciences.
Recent Key Developments and Upcoming Milestones
Research and Clinical Development
Darovasertib: a potential first-in-class PKC inhibitor in Phase 2/3 clinical testing for the treatment of metastatic uveal melanoma (MUM) and as neoadjuvant treatment for primary uveal melanoma (UM).
Exhibit 99.1
Exhibit 99.1
IDE397: a potential first-in-class Phase 2 MAT2A inhibitor for the treatment of MTAP-deletion solid tumors.
IDE849 (SHR-4849): a potential first-in-class Phase 1 DLL3 TOP1i antibody drug conjugate (ADC) targeting small cell lung cancer (SCLC) and neuroendocrine tumors (NETs).
IDE275 (GSK959): a potential first-in-class and best-in-class Phase 1 Werner Helicase inhibitor for the treatment of high microsatellite instability (MSI-High) tumors.
IDE161: a potential first-in-class Phase 1 PARG inhibitor for the treatment of solid tumors.
Exhibit 99.1
IDE705 (GSK101): a potential first-in-class Phase 1 Pol Theta Helicase Inhibitor in combination with PARP inhibitor for the treatment of HRD solid tumors.
IDE892: a potential best-in-class MTA-cooperative PRMT5 inhibitor to enable wholly-owned combination with IDE397.
IDE034: a potential first-in-class B7H3/PTK7 TOP1i bispecific ADC with combination potential with IDE161.
IDE574: a potential first-in-class KAT6/7 dual inhibitor development candidate with combination opportunities with multiple programs in the Company's pipeline.
Corporate Development and Operations
Exhibit 99.1
Financial Results
As of March 31, 2025, IDEAYA had cash, cash equivalents and marketable securities of approximately $1.05 billion. This compared to cash, cash equivalents and marketable securities of approximately $1.08 billion as of December 31, 2024 The decrease in the balance as of March 31, 2025 was primarily driven by net cash used in operations which was offset by $25.0 million in net proceeds from the sale of common stock shares through at-the-market financings during the quarter.
IDEAYA projects that the $1.05 billion in cash, cash equivalent and marketable securities balance as of March 31, 2025 will be sufficient to fund its planned operations into 2029 based on its current operating plan. We have updated our operating plan costs with further pipeline prioritization, including focusing: 1) the IDE161 clinical program on the combination study with DLL3 TOP1 ADC IDE849, 2) the IDE397 and PRMT5 mechanism clinical combination activities to wholly-owned PRMT5 inhibitor IDE892 (PRMT5MTA), and 3) the clinical dose escalation and expansion data for the IDE397 and Trodelvy® combination in MTAP-deletion UC, to be utilized for the MTAP-deletion NSCLC indication clinical expansion activities.
There was no collaboration revenue for the three months ended March 31, 2025, compared to $7.0 million in collaboration for the three months ended December 31, 2024. Collaboration revenue for the three months ended December 31, 2024 was related to a milestone payment from GSK that was earned for the IND clearance of IDE275 (GSK959) in October 2024.
Research and development (R&D) expenses for the three months ended March 31, 2025, totaled $70.9 million compared to $140.2 million for the three months ended December 31,
Exhibit 99.1
2024. The decrease was primarily due to a one-time $75.0 million upfront payment under the license agreement for IDE849 with Hengrui Pharma that occurred in December 2024, offset by higher clinical trial, consulting and personnel-related expenses to support our pipeline.
General and administrative (G&A) expenses for the three months ended March 31, 2025 totaled $13.5 million compared to $11.0 million for the three months ended December 31, 2024. The increase was primarily due to higher personnel-related, consulting and legal patent expenses to support our growth.
The net loss for the three months ended March 31, 2025, was $72.2 million compared to the net loss of $130.3 million for the three months ended December 31, 2024. Total stock compensation expense for the three months ended March 31, 2025, was $10.2 million compared to $9.5 million for the three months ended December 31, 2024.
