Gilbert Syndrome, a total bilirubin =3.0 x ULN, with direct bilirubin =1.5 x ULN)

except for patients with tumor involvement of the liver who must have ALT and AST =5 x
ULN

- Male patients with female partners of childbearing potential and female patients of
childbearing potential are required to use two forms of acceptable contraception,
including one barrier method, during their participation in the study and for 6 months
following last dose of study drug. Male patients must also refrain from donating sperm
during their participation in the study.
- Ability to understand the nature of this study and comply with the study procedures
and laboratory tests.
Exclusion Criteria:
- Patients with brain metastases may be enrolled if radiation and/or surgery have been
completed and follow-up evaluation by computed tomography (CT) or magnetic resonance
imaging (MRI) after 1 month demonstrates stable disease (SD), and the patient does not
require corticosteroids or enzyme-inducing anti-epileptic medications for central
nervous system disease. Patients with SCLC should have brain imaging performed within
the last 2 months prior to study entry.
- More than 3 prior cytotoxic chemotherapy regimens given in the metastatic setting.
- Second-line ovarian cancer patients that are platinum-sensitive.
- Most recent chemotherapy =21 days and unresolved toxicities National Cancer Institute
Common Terminology Criteria for Adverse Events (NCI CTCAE v4.03 Grade =2 (except
alopecia)
- Use of an investigational drug =21 days or 5 half-lives (whichever is shorter) prior
to the first dose of LCL161. For study drugs for which 5 half-lives is =21 days, a
minimum of 14 days between termination of the study drug and administration of LCL161
is required
- Impairment of gastrointestinal function or gastrointestinal disease that may alter
absorption of oral medications
- Major surgery =3 weeks or minor surgical procedures =7 days prior to study entry. No
waiting is required following port-a-cath placement.
- Patients who are currently receiving chronic (>14 days) treatment with corticosteroids
at a dose =10 mg of prednisone (or its glucocorticoid equivalent) per day, or any
other chronic immunosuppressive treatment that cannot be discontinued prior to
starting study drug
- Patients who are currently receiving treatment with agents that are metabolized solely
through cytochrome P450 (CYP) 3A4/5 (CYP3A4/5) and have a narrow therapeutic index or
are strong CYP2C8 inhibitors; or are receiving treatment with agents that carry a risk
for QT prolongation and are CYP3A substrates. Caution should be used in patients
taking other CYP2C8- or CYP3A4/5-interacting agents.
- New York Heart Association (NYHA) Class III or IV heart failure, uncontrolled angina,
severe uncontrolled ventricular arrhythmias, or electrocardiographic evidence of acute
ischemia or active conduction system abnormalities (see Appendix B), prolongation of
the QTc interval to >450 msec for males or >470 msec for females on baseline
electrocardiogram (ECG) per institutional standard or any of the following:
- History or presence of ventricular tachyarrhythmia
- Presence of unstable atrial fibrillation; patients with stable atrial fibrillation are
eligible, provided they do not meet any of the other cardiac exclusion criteria.
- Clinically significant resting bradycardia (<50 bpm)
- Angina pectoris or acute myocardial infarction =3 months prior to starting study drug
- Other clinically significant heart disease (e.g., symptomatic congestive heart
failure, uncontrolled arrhythmia or hypertension)
- Patients who are pregnant (positive beta-human chorionic gonadotropin [ß-HCG]) or
breastfeeding.
- Women of childbearing potential, defined as all women physiologically capable of
becoming pregnant, unless they are using highly effective methods of contraception
during dosing and for at least 6 months after study treatment. Highly effective
methods include:
- Total abstinence or
- Male partner or female sterilization or
- Combination of any two of the following (a+b or a+c or b+c):
- Use of oral, injected, or implanted hormonal methods of contraception
- Placement of an intrauterine device (IUD) or intrauterine system (IUS)
- Barrier methods of contraception: condom for male partner or occlusive cap (diaphragm
or cervical/vault caps) with spermicidal foam/gel/film/cream/vaginal suppository.
Note: Postmenopausal women are allowed to participate in this study. Women are considered
post-menopausal and not of childbearing 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, a
woman is considered to be not of childbearing potential only when her reproductive status
has been confirmed by follow-up hormone level assessment.
- Wide field radiotherapy (including therapeutic radioisotopes such as strontium 89)
administered =28 days or limited field radiation for palliation =7 days prior to
starting study drug or has not recovered from side effects of such therapy
- Known diagnosis of human immunodeficiency virus, hepatitis B, or hepatitis C
Psychological, familial, sociological, or geographical conditions that do not permit
compliance with the protocol.
