IDEAYA Biosciences

IDEAYA Biosciences is a clinical-stage biotech developing precision cancer therapies based on synthetic lethality - when specific gene mutations pair to cause cell death. The company also studies combining synthetic lethality with immunotherapies and DNA damage to enhance treatment efficacy. While current drugs target limited mutations like BRCA1/2, IDEAYA aims to treat broader genetic subpopulations. 

Its pipeline includes synthetic lethality-driven precision medicines across four potential first-in-class clinical-stage product candidates. Of these, the company owns/controls commercial rights of the three most-advanced of these product candidates: darovasertib, IDE397, and IDE161. As of May 2024, the company was also advancing Werner Helicase program for which a development candidate has been selected in collaboration with GlaxoSmithKline, and, subject to investigational new drug-, or IND-, enabling studies, are targeting an IND in 2024. In addition. the company also works on multiple earlier-stage preclinical programs.

By targeting specific genetic drivers, IDEAYA advances precision oncology using synthetic lethality approaches. The company is focused on developing novel targeted therapies for patient populations with high unmet need and limited treatment options.  

In December 2023, IDEAYA Biosciences teamed up with Gilead Sciences to test the combination of IDE397 and Trodelvy in a Phase I clinical trial for MTAP-deletion bladder cancer.

Key partnerships and customers

The company collaborates with pharmaceutical partners to advance its pipeline, including a strategic partnership with GSK in June 2020. The collaboration with GSK covers co-development and commercialization of two synthetic lethality programs. IDEAYA received USD 100 million upfront and USD 20 million in a direct private placement through the GSK deal. In June 2022, IDEAYA announced it would co-develop its Pol Theta candidate with GSK, with a Phase 1 trial starting in the first half of 2023. 

IDEAYA also holds an exclusive license from Novartis for LXS196 (IDE196), a PKC inhibitor for metastatic uveal melanoma. Additionally, the company is exploring IDE196 combinations with Pfizer and its potential in other rare skin diseases. In July 2022, IDEAYA signed an agreement with Amgen to evaluate IDE397 with Amgen's AMG 193 in solid tumors. Strategic pharma partnerships help advance and expand IDEAYA's pipeline of synthetic lethality precision oncology programs.

Funding and financials

The company was listed on the Nasdaq Global Select Market under the ticker symbol “IDYA” in May 2019, raising USD 50 million via an initial public offering. In September 2022, the company raised USD 92 million. 

For 2022, the company reported a net loss of USD 58.7 million (up 17.9% YoY) while collaboration revenue was USD 50.9 million (up 82.3% YoY).

On October 24, 2023, IDEAYA Biosciences priced an underwritten public offering of 5 million shares of common stock and pre-funded warrants to purchase 319,150 shares of common stock. The common stock offered was priced at USD 23.50 per share, while the exercise price of a pre-funded warrant was USD 0.0001. The offering was expected to bring in approximately USD 125 million in gross proceeds.
