• Creatinine within normal institutional limits OR creatinine clearance >= 60 mL/min/1.73 m^2 for patients with creatinine levels above institutional normal
• Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately; men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and for 6 months after completion of study drug administration
• Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria

• Patients who have had cytotoxic anticancer chemotherapy or immune checkpoint inhibitor within 4 weeks (6 weeks for nitrosoureas or mitomycin C) or palliative radiation within 2 weeks (stereotactic radiation therapy [SRS] for brain metastasis within 48 hours) prior to entering the study or those who have not recovered from adverse events (>= grade 2) due to agents administered more than 4 weeks earlier
• Patients receiving cytotoxic agent as immunomodulatory therapy for a non neoplastic indication (e.g. methotrexate for rheumatoid arthritis) and who are unable to discontinue such agents within 2 weeks prior to starting treatment
• Oral targeted therapy within five days or five half-lives, whichever is longer, prior to initiating protocol therapy treatment
• Patients who are receiving any other investigational agents
• Use of strong cytochrome P450, family 3, subfamily A (CYP3A) inhibitors and inducers
• Patients with symptomatic uncontrolled brain metastases are excluded; (patients with stable treated or asymptomatic untreated brain metastasis not requiring glucocorticoids are allowed)
