Toxicities attributed to prior therapy/procedure must have resolved to Grade = 1. Exceptions include alopecia and oxaliplatin induced neurotoxicity = Grade 2. C1D1 treatment will start no more than 28 days after completion of prior cancer treatment. Patients that are > 28 days from completion of prior treatment will need to be discussed with the sponsor-investigator. - Life expectancy of = 16 weeks per estimation of site investigator. - Demonstrate adequate organ function as defined in the table in the protocol.

NOTE: Risk of HBV reactivation should be considered in all patients and the need for anti-HBV prophylaxis should be carefully assessed prior to the initiation of anticancer therapy. Testing is not required at screening. Status should be assessed through medical history and if there is a question testing may be done at the discretion of the investigator based on local guidelines. This testing would be considered standard of care. - Participants who are Hepatitis C antibody positive but Hepatitis C RNA negative due to prior treatment or natural resolution of infection are eligible.

NOTE: Pacemaker, beta blockers or digoxin are permitted. - Ongoing infection > Grade 2 National Cancer Institute (NCI)-Common Terminology Criteria for Adverse Events (CTCAE) version (v)5.0. - Patient taking medications with a known risk to prolong the QTc interval and/or cause Torsades de Pointes. NOTE: Patients must be discontinued = 7 days of registration. Treating physicians may wish to replace the drug(s) that do not carry this risk with safe alternative(s). - Uncontrolled hypertension. (Systolic blood pressure > 140 mmHg or diastolic pressure > 90 mmHg despite optimal medical management). - Seizure disorder requiring medication. - Participant has leptomeningeal disease, carcinomatous meningitis, symptomatic brain metastases, or radiologic signs of CNS hemorrhage.

Replacement therapy (eg, thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment. - Participant has a diagnosis of immunodeficiency or has received systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to initiating protocol therapy. - Participant has received a transfusion (platelets or red blood cells) = 4 weeks prior to initiating protocol therapy. - Participant has received colony stimulating factors (e.g., granulocyte colony-stimulating factor, granulocyte macrophage colony stimulating factor, or recombinant erythropoietin) within 4 weeks prior initiating protocol therapy. - Participant has had any known Grade 3 or 4 anemia, neutropenia or thrombocytopenia due to prior chemotherapy that persisted > 4 weeks and was related to the most recent treatment. - Known hypersensitivity to any of the study drugs, study drug classes, or excipients in the formulation. - Unable to swallow orally administered medications. - Any malabsorption condition and/or patients with gastrointestinal disorders likely to interfere with absorption of the study medication. - History of organ allograft including stem cell or cord blood transplantation. - Co-morbid systemic illnesses or other severe concurrent disease which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and toxicity of the prescribed regimens. Patients considered a poor medical risk due to a serious, uncontrolled medical disorder, non-malignant systemic disease or active, uncontrolled infection. Examples include, but are not limited to, uncontrolled ventricular arrhythmia, recent (within 3 months) myocardial infarction, uncontrolled major seizure disorder, unstable spinal cord compression, superior vena cava syndrome, extensive interstitial bilateral lung disease on high resolution computed tomography (HRCT) scan or any psychiatric disorder that prohibits obtaining informed consent. - Currently receiving any other investigational agent which would be considered as a treatment for the primary neoplasm. - Participant must not have had diagnosis, detection, or treatment of another type of cancer = 2 years prior to initiating protocol therapy (except basal or squamous cell carcinoma of the skin and cervical cancer that has been definitively treated). - Myelodysplastic syndrome/acute myeloid leukemia or with features suggestive of myelodysplastic syndrome/acute myeloid leukemia (MDS/AML). - Concurrent use of warfarin or other warfarin-derived anticoagulant. NOTE: Concurrent use of heparin, direct oral anticoagulants, low molecular weight heparin (LMWH), or fondaparinux is allowed. - Participant taking medications or herbal products including grapefruits, grapefruit hybrids, pomelos, star fruits, Seville oranges, pomegranates, or the juice from any of these. NOTE: Patients must discontinue the drug/product = 7 days prior to registration. - Pregnant or breastfeeding (NOTE: breast milk cannot be stored for future use while the mother is being treated on study). - Judgment by the investigator that the patient should not participate in the study if the patient is unlikely to comply with study procedures, restrictions and requirements. - Substance abuse, medical, psychological or social conditions that may interfere with the patient's participation in the study or evaluation of the study results.

Outcome

Type Measure Description Time frame Safety issue
Primary Progression Free Survival (PFS) Evaluate PFS of patients who achieved a complete response (CR), partial response (PR) or stable disease (SD). PFS is defined as the date of treatment initiation (C1D1) until the criteria for disease progression is met as defined by RECIST 1.1 or death occurs 4-6 months
Secondary Objective Response Rate (ORR) ORR is the proportion of all subjects with confirmed PR or CR as the Best Overall Response according to RECIST 1.1, from treatment initiation (C1D1) until disease progression/recurrence (taking as reference for progressive disease the smallest measurements recorded since the start of treatment). 5 years
Secondary Overall Survival (OS) OS is defined as the period measured from the date of treatment initiation (C1D1) to the date of death from any cause. 5years
Secondary Duration of Response (DOR) DoR is defined as the period measured from the time that RECIST 1.1 criteria are met for complete or partial response (whichever status is recorded first) until the date that recurrent or progressive disease is objectively documented (taking as reference for progressive disease the smallest measurements recorded since treatment started). 5 years
Secondary Disease Control Rate (DCR) Disease control rate (DCR) is the percentage of subjects with SD, PR, or CR according to RECIST 1.1. 5 years
Secondary Frequency and Severity of Adverse Events Adverse events will be assessed using the National Cancer Institution Common Toxicity Criteria for Adverse Events (NCI CTCAE) version 5 5 years
