Note: The patient must have discontinued strong inducers for at least one week and must have discontinued strong inhibitors before the treatment is initiated; switching to a different medication prior to starting study treatment is allowed
Patient is currently receiving warfarin or other Coumarin derived anti-coagulant, for treatment, prophylaxis or otherwise; therapy with heparin, low molecular weight heparin (LMWH), or fondaparinux is allowed
Patients who have other concurrent severe and/or uncontrolled medical conditions that would, in the investigator's judgment, contraindicate patient participation in the clinical study (eg. active or uncontrolled severe infection, chronic active hepatitis, immunocompromised, acute or chronic pancreatitis, uncontrolled high blood pressure, interstitial lung disease, etc.)
Patient has a known history of human immunodeficiency virus (HIV) infection (testing not mandatory) infection

Patient has any of the following cardiac abnormalities:

Symptomatic congestive heart failure

Patient has impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of study drug (e.g., ulcerative diseases, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, or small bowel resection)
Patient has a score >= 12 on the Patient Health Questionnaire (PHQ)-9 questionnaire
Patient selects a response of "1, 2 or 3" to question number 9 on the PHQ-9 questionnaire regarding potential for suicidal thoughts or ideation (independent of the total score of the PHQ-9)

Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive human chorionic gonadotropin (hCG) laboratory test (> 5 mIU/mL); patients with elevated hCG at baseline that is judged to be related to the tumor are eligible if hCG levels do not show the expected doubling when repeated 5-7 days later, or pregnancy has been ruled out by vaginal ultrasound

Patient who does not apply highly effective contraception during the study and through the duration as defined below after the final dose of study treatment:

Sexually active males should use a condom during intercourse while taking drug and for 8 weeks after the final dose of study treatment and should not father a child in this period, but may be recommended to seek advice on conservation of sperm; a condom is required to be used also by vasectomized men in order to prevent delivery of the drug via seminal fluid
Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, must use highly effective contraception during the study and through at least 4 weeks after the final dose of study treatment

Highly effective contraception is defined as either:

Total abstinence: when this is in line with the preferred and usual lifestyle of the subject; (periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods] and withdrawal are not acceptable methods of contraception)
Female sterilization: have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks before taking study treatment; in case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment
Male partner sterilization (with the appropriate post-vasectomy documentation of the absence of sperm in the ejaculate); (for female study subjects, the vasectomized male partner should be the sole partner for that patient)

Use a combination of the following:

Placement of an intrauterine device (IUD) or intrauterine system (IUS)
Barrier methods of contraception: condom or occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/vaginal suppository
Note: hormonal contraception methods (e.g. oral, injected, and implanted) are not allowed
Women are considered post-menopausal and not of child-bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) at least six weeks ago; for women with therapy-induced amenorrhea, oophorectomy or serial measurements of follicle-stimulating hormone (FSH) and/or estradiol are needed to ensure postmenopausal status; NOTE: ovarian radiation or treatment with a luteinizing hormone-releasing hormone (LH-RH) agonist (goserelin acetate or leuprolide acetate) is not permitted for induction of ovarian suppression
