treatment

study drug, with the exception of adequately treated, basal or squamous cell
carcinoma, non-melanomatous skin cancer or curatively resected cervical cancer.

- Impairment of gastrointestinal (GI) function or GI disease that may significantly
alter the absorption of the study drugs (e.g., ulcerative diseases, uncontrolled
nausea, vomiting, diarrhea, malabsorption syndrome, or small bowel resection).

- History of HIV infection (testing not mandatory).

- Other concurrent severe and/or uncontrolled medical condition that would, in the
investigator's judgment, cause unacceptable safety risks, contraindicate patient
participation in the clinical study or compromise compliance with the protocol.

- Clinically significant, uncontrolled heart disease and/or cardiac repolarization
abnormalities.

- History of acute coronary syndromes (including myocardial infarction, unstable
angina, coronary artery bypass grafting, coronary angioplasty, or stenting) or
symptomatic pericarditis within 6 months prior to screening

- History of documented congestive heart failure (New York Heart Association
functional classification III-IV)

- Documented cardiomyopathy

- Left Ventricular Ejection Fraction (LVEF) <50% as determined by Multiple Gated
acquisition (MUGA) scan or echocardiogram (ECHO) at screening

- Clinically significant cardiac arrhythmias (e.g. ventricular tachycardia),
complete left bundle branch block, high-grade AV block (e.g. bifascicular block,
Mobitz type II and third-degree AV block)

- Long QT syndrome or family history of idiopathic sudden death or congenital long
QT syndrome, or any of the following:

- Risk factors for Torsades de Pointe (TdP) including uncorrected hypokalemia or
hypomagnesemia, history of cardiac failure, or history of clinically
significant/symptomatic bradycardia.

- Concomitant use of medication(s) with a known risk to prolong the QT interval
and/or known to cause Torsades de Pointe that cannot be discontinued (within 5
half-lives or 7 days prior to starting study drug) or replaced by safe
alternative medication

- Inability to determine the QT interval on screening (QTcF, using Fridericia's
correction)

- Systolic blood pressure (SBP) >160 mmHg or <90 mmHg at screening

- Currently receiving any of the following medications and cannot be discontinued 7 days
prior to starting study drug:

- Known strong inducers or inhibitors of CYP3A4/5, including grapefruit, grapefruit
hybrids, pomelos/pummelos, star-fruit, pomegranates or pomegranate juice and
Seville oranges

- That have a narrow therapeutic window and are predominantly metabolized through
CYP3A4/5

- Herbal preparations/medications, dietary supplements known as strong inhibitors
or inducers of CYP3A4 or those with a known risk of QT prolongation. (Does not
include Ca, Mg, Vit D or KCl supplements).

- Currently receiving warfarin or other coumarin-derived anticoagulant for treatment,
prophylaxis or otherwise. Therapy with heparin, low molecular weight heparin (LMWH) or
fondaparinux is allowed.

- Participation in a prior investigational study within 30 days prior to enrollment or
within 5 half-lives of the investigational product, whichever is longer.

- Major surgery within 14 days prior to starting study drug or has not recovered from
major side effects (tumor biopsy is not considered as major surgery).

- Has not recovered from all toxicities related to prior anticancer therapies to
NCI-CTCAE version 4.03 Grade <1 (Exception to this criterion: patients with grade 1
taxane-induced neuropathy, any grade of alopecia, amenorrhea or other toxicities not
considered a safety risk for the patient as per investigator's discretion, are allowed
to enter the study.).

- Child-Pugh score B or C.

- History of non-compliance to medical regimen.

- 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 hCG laboratory test.]

- Women of child-bearing potential, defined as all women physiologically capable of
becoming pregnant, unless they are using highly effective methods of contraception
during dosing and for 3 months after the last dose of study treatment. Highly
effective contraception methods include:

- 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 sterilization (at least 6 months prior to screening) with the appropriate
post-vasectomy documentation of the absence of sperm in the ejaculate. For female
subjects on the study the vasectomized male partner should be the sole partner
for that subject.

- Use of oral, injected or implanted hormonal methods of contraception or placement
of an intrauterine device (IUD) or intrauterine system (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.

- Note: Oral contraceptives are allowed but should be used in conjunction with a
barrier method of contraception due to unknown effect of drug-drug interaction.

- 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 six 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 21 days after stopping treatment and should not father a child in this period.
A condom is required to be used also by vasectomized men in order to prevent delivery
of the drug via seminal fluid.
