Darovasertib (PKC Inhibitor) – Addressing Unmet Needs in Uveal Melanoma
Darovasertib, IDEAYA's most advanced clinical-stage product candidate, is a potent, selective small molecule inhibitor of protein kinase C (PKC) that the company is developing for genetically-defined cancers having GNAQ or GNA11 gene mutations. The company has achieved double-digit patient enrollment and has opened multiple clinical sites, including international sites, in its potential registration-enabling Phase 2/3 clinical trial, designated as IDE196-002, evaluating darovasertib in combination with crizotinib, Pfizer's investigational cMET inhibitor, in patients having metastatic uveal melanoma (MUM) with HLA-A*02:01 negative (HLA-A2(-)) serotype.
IDEAYA is also planning to enroll additional HLA-A*02:01 positive (HLA-A2(+)) patients as an independent clinical strategy to address HLA-A2(+) MUM patients in its ongoing Phase 2 clinical trial, designated as IDE196-001. The company has separately initiated and achieved double-digit patient enrollment in its Phase 2 clinical trial, designated as IDE196-009, evaluating darovasertib as single-agent neoadjuvant and adjuvant therapy in patients having primary uveal melanoma (UM).
IDE397 (MAT2A Inhibitor) – Targeting MTAP-Deleted Tumors
IDE397 is a clinical-stage, potent, selective small molecule inhibitor of methionine adenosyltransferase 2a (MAT2A) that IDEAYA is developing for patients having solid tumors with MTAP deletion. The company is enrolling patients into a Phase 2 clinical trial designated as IDE397-001 to evaluate IDE397 for patients having certain tumors with MTAP gene deletion, with a focus on high priority solid tumor types, including non-small cell lung cancer (NSCLC) and bladder cancers.
IDEAYA is also collaborating with Amgen to clinically evaluate IDE397 in combination with AMG 193, Amgen's investigational MTA-cooperative PRMT5 inhibitor, in patients having tumors with MTAP deletion, in an Amgen-sponsored clinical trial. Additionally, the company is collaborating with Gilead to clinically evaluate IDE397 in combination with sacituzumab-govitecan-hziy (Trodelvy), Gilead's Trop-2 directed antibody-drug conjugate, in patients having MTAP deletion bladder cancer.
IDE161 (PARG Inhibitor) – Addressing Homologous Recombination Deficiency
IDEAYA is evaluating IDE161, a small molecule inhibitor of poly (ADP-ribose) glycohydrolase (PARG), in a Phase 1/2 clinical trial designated as IDE161-001 for patients having tumors with homologous recombination deficiency (HRD) and potentially other genetic and/or molecular signatures. The company is progressing with enrollment of patients having tumors with HRD into the Phase 1 expansion portion of the trial in selected priority tumors, while also continuing with Phase 1 dose optimization to confirm a move-forward expansion dose for the planned Phase 2 portion of the trial.
GSK101 (Pol Theta Helicase Inhibitor) – Targeting Homologous Recombination Deficiency
IDEAYA discovered GSK101 (IDE705), its DNA Polymerase Theta (Pol Theta) Helicase inhibitor clinical development candidate, and is evaluating it in preclinical studies in collaboration with GlaxoSmithKline (GSK). GSK101 targets the helicase domain of the Pol Theta protein for patients having solid tumors with BRCA or other mutations associated with HRD. GSK is evaluating GSK101 in combination with niraparib, GSK's small molecule inhibitor of PARP, for the treatment of patients having tumors with BRCA or other HR mutations, or HRD, in a GSK-sponsored Phase 1 clinical trial.
Werner Helicase Inhibitor – Addressing High Microsatellite Instability
IDEAYA is advancing its preclinical IND-enabling studies and other preclinical research in collaboration with GSK for an inhibitor targeting Werner Helicase (WRN) for patients having tumors with high microsatellite instability (MSI). A Werner Helicase Inhibitor development candidate has been selected, and the company, in collaboration with GSK, has completed the IND-enabling GLP toxicology studies, targeting an IND submission in the second half of 2024 to enable first-in-human clinical evaluation.
Robust Precision Medicine Pipeline and Platform
In addition to its four clinical-stage product candidates, IDEAYA has initiated early preclinical research programs focused on pharmacological inhibition of several new targets for patients with solid tumors characterized by defined biomarkers based on genetic mutations and/or molecular signatures. The company is targeting development candidate nominations in the second half of 2024 for multiple new targets, including a development candidate to treat MTAP-deletion solid tumors to enable a potential wholly-owned clinical combination with IDE397.
IDEAYA's core research has been and continues to be focused on precision medicine oncology, with synthetic lethality as a central tenet. The company has invested significantly and continues to invest in capabilities for identification and validation of new precision medicine targets and biomarkers for patient selection, further strengthening its multi-pronged clinical and business strategy.
Collaborations and Partnerships
IDEAYA has established selective, value-accretive collaborations with leading pharmaceutical companies to support its clinical development activities. These include collaborations with GlaxoSmithKline, Pfizer, Amgen, Gilead, Merck, and others, which provide access to complementary compounds and expertise, as well as potential milestone and royalty payments.
Liquidity
As of March 31, 2024, IDEAYA had $941.4 million in cash, cash equivalents, and marketable securities, providing a strong financial foundation to advance its pipeline and support its ongoing operations. The company believes that its current cash position will be sufficient to fund its planned operations for at least the next 12 months.
Risks and Challenges
IDEAYA faces various risks and challenges common to the biotechnology industry, including the ability to successfully develop and obtain regulatory approval for its product candidates, the potential for competition from other therapies, and the need to continue raising capital to fund its operations. The company's ability to generate revenue is also dependent on the successful commercialization of its product candidates, which may be affected by factors such as pricing, reimbursement, and market acceptance.
Conclusion
IDEAYA Biosciences is a precision medicine oncology company with a robust pipeline of promising clinical-stage product candidates and a strong financial position. The company's focus on developing targeted therapies for genetically-defined patient populations, coupled with its strategic collaborations and investments in its precision medicine platform, position it well to address significant unmet medical needs in oncology and drive long-term value for its shareholders.
