Stable/treated brain metastases are permitted (defined as history of brain metastases previously treated with surgical resection or stereotactic radiosurgery, stable on baseline screening study MRI brain for at least 2 months (compared to comparator MRI brain) and asymptomatic without requirement for steroids or antiseizure medications
• Persistent toxicities from previous systemic antineoplastic treatments of Grade >1, excluding alopecia and vitiligo
• Systemic antineoplastic therapy or prohibited co-medications within 5 half-lives or 4 weeks, whichever is shorter, prior to first dose of the study drug, including investigational agents
• Wide-field radiotherapy (e.g., >30% of marrow-bearing bones) within 4 weeks, or focal radiation with palliative intent outside the field of measurable disease within 2 weeks prior to first dose of the study drug
• Major surgery within 4 weeks prior to first dose of study drug, or no recovery from side effects of such intervention
• Hepatic insufficiency manifesting as clinical jaundice, hepatic encephalopathy, and/or variceal bleed within 60 days prior to study entry
• Prior allogeneic bone marrow transplantation

• Gastrointestinal obstruction or radiographic evidence of gastrointestinal obstruction within 4 weeks prior to the first dose of study drug
• Vaccination with a live vaccine ≤30 days prior to first dose of study drug
• Use of a strong cytochrome P450 (CYP)3A4 or CYP1A2 inducer or inhibitor ≤14 days prior to first dose of study drug or inability to discontinue use of a strong CYP3A4 or CYP1A2 inducer or inhibitor for the duration of the study

Other malignancies with low risk of recurrence may also be considered following discussion with the Medical Monitor
• Acute and/or clinically significant bacterial, fungal, or viral infection including hepatitis B (HBV), hepatitis C (HCV), known human immunodeficiency virus (HIV); Note: patients with chronic HBV, HCV or HIV infection will be eligible if they are considered upon a mutual agreement of the Investigator and the Medical Monitor as safe for enrollment and meet one of the following additional conditions:; Patients with HIV infection are on an established antiretroviral therapy for at least 4 weeks, and have CD4+ T-cell counts ≥350 cells/µL and HIV viral load <50 copies/mL,; Patients with serologic evidence of chronic HBV infection receive concurrent anti-HBV therapy and have HBV viral load below the limit of quantification,; Patients with a history of HCV infection must have completed curative anti-HCV therapy and have HCV viral load below the limit of quantification,; Patients on concurrent anti-HCV therapy have HCV viral load below the limit of quantification
