• •Use of amiodarone within 90 days prior to first dose
• •Current use of therapeutic doses of warfarin sodium or any other coumadin-derivative anticoagulants. Heparin and/or low molecular weight heparins are allowed
• •Absolute neutrophil count (ANC) =\< 1,000/mm\^3 (1.0 x 10\^9/L)

• •Hemoglobin =\< 9.0 g/dL
• •Total bilirubin \>= 1.5 x upper limit of normal (ULN) unless associated with patient's primary cancer and/or metastases and with principal investigator's approval
• •Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) \>= 3 x ULN unless associated with patient's primary cancer and/or metastases and with principal investigator's approval
• •Alkaline phosphatase \>= 2.5 x ULN unless associated with patient's primary cancer and/or metastases and with principal investigator's approval
• •Calculated or measured creatinine clearance of \< 40 mL/min
• •Calcium-phosphate homeostasis:
• •* Inorganic phosphorus outside of institutional normal limits
• •* Total serum calcium (can be corrected) outside of institutional normal limits
• •Clinically significant cardiac disease including any of the following:
• •* Congestive heart failure requiring treatment (New York Heart Association \[NYHA\] grade \>= 2), left ventricular ejection fraction (LVEF) \< 50% as determined by multi-gated acquisition (MUGA) scan or echocardiogram (ECHO), or uncontrolled hypertension (refer to World Health Organization \[WHO\] and International Society for Hypertension \[ISH\] guidelines)
• •* History or presence of clinically significant ventricular arrhythmias, atrial fibrillation, resting bradycardia, or conduction abnormality
• •* Unstable angina pectoris or acute myocardial infarction =\< 3 months prior to starting study drug
• •* Corrected QT using Fridericia's formula (QTcF) \> 470 msec (males and females)
• •* History of congenital long QT syndrome
• •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
• •Women of child-bearing potential (WOCBP), defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during dosing and for 3 months following the discontinuation of study treatment. Highly effective contraception methods include:
• •* Total abstinence (when this is in line with the preferred and usual lifestyle of the patient. 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 sterilization (at least 6 months prior to screening). For female patients on the study the vasectomized male partner should be the sole partner for that patient
• •* Use of oral, injected or implanted hormonal methods of contraception or placement of an intrauterine device (IUD) or intrauterine systems (IUS), or other forms of hormonal contraception that have comparable efficacy (failure rate \< 1%), for example hormone vaginal ring or transdermal hormone contraception
• •* In case of use of oral contraception women should have been stable on the same pill for a minimum of 3 months before taking study treatment. 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) or tubal ligation at least 6 weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow-up hormone level assessment is she considered not of child bearing potential
• •Sexually active males unless they use a condom during intercourse while taking drug and for 3 months after the last dose of the study drug and should not father a child in this period. A condom is required to be used also by vasectomized men as well as during intercourse with a male partner in order to prevent delivery of the drug via seminal fluid
