New drug targets rare genetic cancers in early trial
NCT ID NCT03947385
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new drug called IDE196 in people with certain cancers that have specific genetic mutations (GNAQ/11 or PRKC fusions). The cancers include metastatic uveal melanoma, cutaneous melanoma, and colorectal cancer. The trial has two phases: first to find safe doses, then to see if the drug shrinks tumors. About 336 adults will take part.
Why investors are watching
Ideaya Biosciences is running a Phase 1/2 trial of its drug IDE196 in patients with certain gene mutations linked to several solid tumors, including metastatic uveal melanoma. For a small company, this trial is a core test of whether its lead drug works and is safe, and the results will heavily shape its value and future.
If it works: If the trial shows IDE196 shrinks tumors or slows their growth, Ideaya could move the drug toward later-stage testing and eventual approval. A positive readout could also attract larger partners or funding to develop the drug further.
If it fails: The trial could fail to show enough benefit or reveal safety problems, which is common in early cancer drug testing. A failure or delay would likely hurt Ideaya's prospects, since the company's value depends heavily on this drug succeeding.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Patient must be ≥18 years of age and able to provide written informed consent * Diagnosis of the following: o MUM: Uveal melanoma with histological or cytological confirmed metastatic disease. Metastatic disease may be treatment naïve or have progressed on or after most recent therapy. If the most recent therapy was an immune-oncology agent, PD must be confirmed. \- If a patient is treatment naïve and human leukocyte antigen (HLA)-A\*02:01 positive\*\*\*, documentation is required to provide rationale why treatment with tebentafusp is not the ideal firstline treatment approach or of the patient's intolerance to tebentafusp. \*\*\*To be enrolled in the HLA-A\*02:01 positive cohort, HLA status must be documented by test results from a CAP/CLIA-certified laboratory. * Measurable disease per RECIST v1.1 * Eastern Cooperative Oncology Group ≤1 and expected life expectancy of \> 3 months * Adequate organ function at screening * Adequate contraceptive measures for non-sterilized male and female patients of childbearing potential Crizotinib Combination Additional Inclusion Criteria: * Prior chemotherapy other therapies as applicable or major surgeries must have been completed at least 4 weeks prior to initiation of crizotinib * Patients with preexisting peripheral neuropathy can be included if it is Grade 1 or lower, prior to initiation of crizotinib Biopsy-eligible patients * Accessible lesion(s) that permit a total of at least two biopsies without unacceptable risk of a significant procedural complication. Exclusion Criteria: * Previous treatment with a PKC inhibitor * Known MSI-H/dMMR tumors who have not previously received immune checkpoint inhibitors * Known symptomatic brain metastases * Adverse events from prior anti-cancer therapy that have not resolved * Known acquired immunodeficiency syndrome (AIDS)-related illness, hepatitis B virus, or hepatitis C virus * Active infection requiring ongoing therapy * Recent surgery or radiotherapy * Prior gastrectomy or upper bowel removal or any other gastrointestinal disorder or defect * Females who are pregnant or breastfeeding * Impaired cardiac function * Treatment with prohibited medications that cannot be discontinued prior to study entry * For patients receiving IDE196 powder-in-capsule (PIC) formulation or crizotinib, allergy to mammalian meat products and gelatin Crizotinib Combination Additional Exclusion Criteria: * Prior therapy directly targeting ALK, MET, or ROS1 * Spinal cord compression * History of pneumonitis or interstitial lung disease * History of syncope * History of thromboembolic or cerebrovascular events ≤12 weeks prior to first dose of study treatment PK Substudy (optional) with Pravastatin Additional Exclusion Criteria: * Taken any dose of statin or inhibitor of organic anion transporting polypeptide within 7 days prior to enrollment in the study and cannot refrain from them through C2D1 * Taken drugs that interfere with the absorption, metabolism, or elimination of pravastatin * Any contraindication associated to the use of statins or hypersensitivity component of pravastatin * Active liver disease DDI Cocktail Substudy Additional Exclusion Criteria: * Treatment with bupropion, repaglinide, flurbiprofen, omeprazole, esomeprazole, midazolam, and dabigatran etexilate within 7 days prior to Cycle 1 Day -1. * Intake of vitamin supplements containing Vitamin B6 (pyridoxine), grapefruit/grapefruit juice, or Seville orange juice within 7 days prior to Cycle 1 Day -1. * Intake of any strong or moderate inhibitor of CYP2B6, CYP2CI, CYP2C9, CYP2C10 and OAT3 is prohibited within 7 days or within 5 half-lives, whichever is longer, of Cycle 1 Day -1. * Moderate and strong inhibitors of CYP2A4/5 or P-gp are prohibited within 7 days, or within 5 half-lives, whichever is longer, of Cycle 1 Day -1. * Intake of strong or moderate inducers of CYP3A4/5, CYP2B6, CYP2C9, CYP2C19, or OAT3 is prohibited during 15 days, or 5 half-lives, whichever is longer, prior to Cycle 1 Day -1.
