This is a Phase 1 study to assess the safety and clinical activity of RO7623066 alone and in combination in patients with advanced solid tumors.


This is a Phase 1 study consisting of 2 parts: Dose Escalation and Expansion to evaluate the safety, tolerability, clinical activity, and pharmacokinetics (PK) Study of RO7623066 as a Monotherapy or in Combination in Patients with Advanced Solid Tumors, and a Food Effect Cohort.


Advanced Solid Tumors, Neoplasms, Carboplatin, Olaparib

  9. Female patients who are women of childbearing potential (WOCP) (defined as physiologically and anatomically capable of becoming pregnant), confirmed of a negative pregnancy test and agreement to the use of a highly effective contraceptive method or at least 2 effective methods at the same time during study treatment period and for up to 3 months after the last dose of study treatment. Male patients must be willing to use effective barrier contraception (ie, condoms) during the study treatment period and for up 3 months after the last dose of study treatment
  10. Capable of understanding and complying with protocol requirements
  11. Signed and dated institutional review board (IRB)/independent ethics committee (IEC) approved informed consent form (ICF) before any protocol-directed Screening procedures are performed
  12. Does not require ongoing treatment with strong or moderate CYP3A4 inhibitors or inducers.
  13. Histologically or cytologically confirmed locally advanced (unresectable) or metastatic solid tumors who meet one of the following criteria (dose escalation only):
    1. Relapsed or progressed through standard therapy
    2. Have a disease for which no standard effective therapy exists
    3. Not a candidate for standard effective therapy Note: In men with prostate cancer, baseline testosterone levels must also be ≤ 50 ng/dL (≤ 2.0 nM) and surgical or ongoing medical castration must be maintained throughout the duration of the study

  1. Prior anticancer treatment including:
    1. Chemotherapy or small molecule-targeted therapy < 2 weeks prior to first dose of study treatment
    2. Any antibody therapy < 5 half-lives from first dose of study treatment (or 4 weeks since last therapy, whichever is the shortest)

    4. Invasive surgery requiring general anesthesia < 30 days from first dose of study treatment
    5. Chemotherapy with nitrosoureas or mitomycin C < 45 days from first dose of study treatment
    6. Radiation therapy (including radiofrequency ablation) < 4 weeks prior to initiation of study treatment Note: Prior stereotactic body radiation therapy or local palliative radiation is allowed < 2 weeks prior to first dose of study treatment
  2. Ongoing Grade 2 or greater toxicity, except alopecia, related to any prior treatment (ie, chemotherapy, targeted therapy, radiation, or surgery)
  3. Prolongation of QT/QTc interval (QTc interval > 480 msec) using the Frederica method of QTc analysis
  4. Women who are pregnant or nursing
  5. Seropositive for human immunodeficiency virus (HIV) 1 or 2 or acquired immunodeficiency syndrome or active infection with hepatitis B virus (HBV) or hepatitis C virus (HCV) (Note: Patients with positive HCV antibody may be eligible if HCV ribonucleic acid [RNA] is undetectable on a quantitative HCV RNA assay, the Medical Monitor is available for advice)
  6. Primary malignant brain tumor
  7. Symptomatic and/or untreated brain metastases, active leptomeningeal disease, or central nervous system malignant disease requiring steroids or other therapeutic intervention Note: Patients with definitively treated brain metastases will be considered for enrollment after seeking advice from the Medical Monitor and must be clinically stable for ≥ 2 weeks prior to the start of treatment
  8. Previous solid organ or hematopoietic cell transplant
  9. Need for treatment with steroids at stable doses (> 10 mg prednisone or equivalent per day). Note: Oral steroids up to 10 mg/day, topical, ophthalmic, or inhaled steroid medications are allowed
  10. Uncontrolled hypertension > 150/100 mm Hg despite aggressive therapy
  11. Concurrent participation in any other investigational therapeutic study
  12. History of stroke, transient ischemic attack, unstable angina, or myocardial infarction within 3 months prior to first dose of study treatment
  13. Unable to swallow whole tablets or capsules. Nasogastric or gastric-tube (G-tube)administration is not allowed
  14. GI disease that would impair ability to swallow, retain, or absorb drug is not allowed
  15. Uncontrolled concurrent disease or illness including but not limited to:

  16. Other severe, acute, or chronic medical condition or laboratory abnormality that may increase the risk associated with study participation or study drug administration, or that may interfere with the interpretation of the study results, and in the judgment of the Investigator, would make the patient inappropriate for the study
