Werner Helicase
IDEAYA is advancing preclinical research for an inhibitor targeting Werner Helicase for tumors with high microsatellite instability (MSI). IDEAYA and GSK are collaborating on ongoing preclinical research, and GSK will lead clinical development for the Werner Helicase program. Highlights:
- Observed dose-dependent cellular viability effect and dose-dependent cellular PD response in multiple endogenous MSI high cell lines

Darovasertib (IDE196)
IDEAYA continues to execute on its clinical trial strategy to evaluate darovasertib (IDE196), a potent and selective PKC inhibitor.
IDEAYA is evaluating darovasertib in combination with crizotinib, a cMET inhibitor, in metastatic uveal melanoma (MUM). The company is also clinically evaluating darovasertib as a combination with crizotinib in GNAQ/11 mutant skin melanoma in an ongoing arm of the current clinical trial, and in adjuvant primary uveal melanoma (UM) as monotherapy through an investigator sponsor clinical trial (IST). IDEAYA is also evaluating other potential darovasertib expansion opportunities, including in cMET driven tumors and in KRAS-mutation tumors.
Darovasertib / Crizotinib Combination Therapy
IDEAYA is continuing patient enrollment into the darovasertib / crizotinib combination arm of the Phase 1/2 clinical trial under clinical trial collaboration and supply agreements with Pfizer. Highlights:
- As of March 1, 2022, the company has enrolled 53 MUM patients into the darovasertib/crizotinib combination arm, and is continuing patient enrollment in the dose expansion cohort of this combination arm
- IDEAYA presented darovasertib and crizotinib clinical combination data in December 2021. As of data and analyses cutoff on November 25, 2021, twenty-two heavily pre-treated MUM patients (
91% with prior therapies, and59% with 2 or more prior therapies) had enrolled in the darovasertib and crizotinib combination arm at the expansion dose, with sixteen evaluable patients who had received one or more tumor scans and six patients who were awaiting their 1st tumor scan. Thirteen patients had received two or more tumor scans for evaluation of potential response. The reported preliminary data, based on an unlocked database, showed robust clinical activity with manageable side effect profile: 100% Disease Control Rate (DCR): 16 of 16 evaluable patients with >1 post-baseline scan showed tumor shrinkage as determined by target lesion size reduction31% Overall Response Rate (ORR): 4 of 13 patients with > 2 post-baseline scans had a confirmed partial response (PR) as determined by RECIST 1.1 based on investigator or central review; and no patients have come off-treatment prior to the 2nd scan46% of patients (6 of 13) with > 2 post-baseline scans observed >30% tumor reduction, including one patient with an unconfirmed PR as determined by RECIST 1.1 is awaiting follow-on tumor scan- Observed side effect profile in MUM patients (n=22) showed a low rate of drug-related serious adverse events (SAE's) and predominantly Grade 1 or 2 drug-related adverse events; eighteen patients experienced a drug-related AE, of which six patients observed Grade 3, and no patients observed Grade 4 or Grade 5
- These data provide clinical proof-of-concept for the darovasertib and crizotinib synthetic lethal combination treatment, and are consistent with the company's translational research discovery that Phase 1 clinical response to darovasertib monotherapy associated with low cMET activity, as measured by gene signature score
- The company is targeting a clinical data update for darovasertib and crizotinib combination in mid-2022, including tolerability and clinical efficacy. IDEAYA is also planning to seek FDA regulatory guidance for potential registration-enabling trial design to evaluate darovasertib and crizotinib combination in MUM in mid-2022. The timing of the clinical data and FDA regulatory guidance may be influenced by data maturity, including observation of median duration of response (DOR) or median progression free survival (mPFS).
- Expanded relationship with Pfizer under a clinical collaboration and supply agreement to support clinical evaluation of darovasertib and crizotinib combination in a potential registration-enabling clinical trial in MUM, subject to FDA feedback and guidance
- Associated cMET expression and activation to observed clinical response based on a retrospective analysis of human clinical biopsies from the Novartis darovasertib Phase 1 clinical trial, supporting cMET expression / activation as potential combination agent
- Observed preclinical synergies between darovasertib and crizotinib in relevant cellular models under conditions simulating a tumor microenvironment in the liver, the site of approximately
90% of uveal melanoma metastases; study data reported at AACR 2021
Darovasertib Monotherapy
IDEAYA has completed enrollment into its ongoing Phase 1/2 clinical trial evaluating darovasertib as monotherapy in MUM patients.
IDEAYA is planning to initiate an Investigator Sponsored Trial, with St. Vincent's Hospital Sydney Limited to evaluate IDE196 as monotherapy in a neo-adjuvant / adjuvant setting in (non-metastatic) uveal melanoma (UM) patients. Data from this clinical trial may offer proof of concept on its hypothesis that earlier treatment of UM patients with IDE196, prior to tumor metastasis, may lead to improved patient outcomes.
Darovasertib – Other Potential Indications
IDEAYA is evaluating the potential for darovasertib in other oncology indications, including in cMET-driven tumors and in KRAS-mutation tumors. The company is also evaluating darovasertib for potential treatment of GNAQ mutation-mediated rare diseases, including Sturge-Weber Syndrome (SWS) and Port Wine Stains (PWS), neurocutaneous disorders characterized by capillary malformations and associated with mutations in GNAQ. Highlights:
- Expanded its relationship with Pfizer under a clinical collaboration and supply agreement for clinical evaluation of darovasertib and crizotinib combination therapy in cMET-driven tumors, such as NSCLC or HCC, subject to preclinical validation studies
- Evaluating darovasertib in combination with a KRAS inhibitor in preclinical studies in KRAS-driven solid tumors
General
IDEAYA continues to monitor Covid-19 and its potential impact on clinical trials and timing of clinical data results. Initiation of clinical trial sites, patient enrollment and ongoing monitoring of enrolled patients, including obtaining patient computed tomography (CT) scans, may be impacted for IDEAYA clinical trials evaluating IDE397 and darovasertib; the specific impacts are currently uncertain.
