  • Presence of metastatic disease that has progressed during or following previous treatment.
  • Presence of radiographically measurable disease.
  • +14 more criteria

You may not qualify if:

  • Malignancy involving the central nervous system unless brain metastases have been previously treated with radiotherapy, have been stable for ≥4 weeks, and do not require corticosteroids.
  • Presence of another cancer with disease manifestations or therapy that could adversely affect subject safety or longevity, create the potential for drug-drug interactions, or compromise the interpretation of study results.
  • Uncontrolled ongoing systemic bacterial, fungal, or viral infection (including upper respiratory tract infection) at the time of start of study therapy.
  • Significant cardiovascular event or comorbidity.
  • Significant screening ECG abnormalities.
  • Pregnancy or breastfeeding.
  • Major surgery within 4 weeks before the start of study therapy.
  • Use of a strong inhibitor or inducer of CYP3A4 or CYP1A2.
  • Use of a drug known to prolong the QT interval within 7 days prior to the start of study drug administration.
  • Concurrent participation in another therapeutic or imaging clinical trial.
  • Other conditions likely to interfere with a subject's ability to participate in the study.
