- A female subject is eligible to participate if she is of: Non-childbearing potential
defined as pre-menopausal females with a documented tubal ligation, hysteroscopic
tubal occlusion procedure with follow-up confirmation of bilateral tubal occlusion,
hysterectomy, or documented bilateral tubal oophorectomy; or postmenopausal defined as
12 months of spontaneous amenorrhea [in questionable cases a blood sample with
simultaneous follicle stimulating hormone (FSH) >40 units (U)/mL and estradiol <40
picograms (pg)/mL (<140 picomoles (pmol)/L) is confirmatory]. Females on hormone
replacement therapy (HRT) and whose menopausal status is in doubt will be required to
use one of the contraception methods if they wish to continue their HRT during the
study. Otherwise, they must discontinue HRT to allow confirmation of post-menopausal
status prior to study enrollment. For most forms of HRT, at least 2 to 4 weeks will
elapse between the cessation of therapy and the blood draw; this interval depends on
the type and dosage of HRT. Following confirmation of their post-menopausal status,
they can resume use of HRT during the study without use of a contraceptive method.
Child-bearing potential and agrees to use one of the contraception methods for an
appropriate period of time (as determined by the product label or investigator) prior
to the start of dosing to sufficiently minimize the risk of pregnancy at that point.
Female subjects must agree to use contraception until 7 months after the last dose of
study medication. Negative serum pregnancy test <=7 days prior to first study drug
dose. Female subjects who are lactating must discontinue nursing prior to the first
dose of study treatment and must refrain from nursing throughout the treatment period
and for 5 half-lives of GSK2820151 or at least 28 days (whichever is longer) following
the last dose of study treatment.
- Male subjects with female partners of child bearing potential must agree to use one of
the methods of contraception specified. This method must be used from the time of the
first dose of study medication until 16 weeks after the last dose of study medication.
In addition, male subjects whose partners are or become pregnant on study medication
must continue to use condoms for 7 days after stopping study medication

immunodeficiency virus (HIV) or solid organ transplant.
- More than three prior lines of cytotoxic therapy.
- Recent prior therapy, defined as follows: 1) Any investigational or Food and Drug
Administration (FDA)-approved anti-cancer drug within 14 days or 5 half-lives,
whichever is longer, prior to the first dose of GSK2820151. Any nitrosoureas or
mitomycin C within 42 days prior to the first dose of GSK2820151. Prior therapy with
monoclonal antibodies is permitted so long as 14 days have elapsed since therapy and
all therapy-related toxicity has resolved to Grade 1 or less. Note that an
investigational drug is defined as a drug without an approved oncologic indication.
2) Any radiotherapy within 14 days or major surgery within 28 days prior to the first
dose of GSK2820151.
3) Anti-androgen therapies for prostate cancer, such as bicalutamide, must be stopped
4 weeks prior to enrollment. Second-line hormone therapies such as enzalutamide,
abiraterone, or orteronel should be stopped 2 weeks prior to enrolment. Subjects with
prostate cancer should remain on luteinizing hormone releasing hormone (LHRH) agonists
or antagonists. Subjects with prostate cancer may also remain on low-dose prednisone
or prednisolone (up to 10 milligrams [mg]/day) and still be eligible for this study.
4) In addition, any therapy-related toxicity must have resolved to Grade 1 or less,
with the exception of alopecia (acceptable at any Grade) and peripheral neuropathy

dose of corticosteroids for at least 1 month prior to study Day 1 are permitted.
Stability of brain metastases must be confirmed with imaging. Subject treated with

esophageal or gastric varices, persistent jaundice or cirrhosis
- Presence of hepatitis B surface antigen (HBsAg) or positive hepatitis C antibody test
result at screening or within 3 months prior to first dose of study treatment. History
