institutional normal

- Women of childbearing potential and men must agree to use adequate contraception
(hormonal or barrier method of birth control, abstinence) prior to study entry and
for the duration of study participation. Should a woman become pregnant or suspect
she is pregnant while participating in this study, she must inform her treating

- Patient must not have a history or current evidence/risk of retinal vein occlusion
(RVO) or central serous retinopathy (CSR), including a history of predisposing
factors to RVO or CSR (e.g., uncontrolled glaucoma or ocular hypertension,
uncontrolled systemic disease such as hypertension, diabetes mellitus, or history of
hyperviscosity or hypercoagulability syndromes) or visible retinal pathology as
assessed by ophthalmic exam that is considered a risk factor for RVO or CSR (such as
evidence of new optic disc cupping, evidence of new visual field defects, or
intraocular pressure > 21 mmHg).

- Patient must not have known symptomatic leptomeningeal or brain metastases or spinal
cord compression.

- Patient must not have a history of allergic reactions attributed to compounds of
similar chemical or biologic composition to GSK1120212 or other agents used in the
study.

- Patient must not have any clinically significant gastrointestinal abnormalities that
may alter absorption such as malabsorption syndrome or major resection of the stomach
or bowels.

- Patient must not have an uncontrolled intercurrent illness including, but not limited
to, ongoing or active infection symptomatic congestive heart failure, unstable angina
pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would
limit compliance with study requirements.

study treatment.

registration are eligible)

- History of acute coronary syndromes (including myocardial infarction and unstable
angina), coronary angioplasty, or stenting within 6 months prior to registration

- History or evidence of current > Class II congestive heart failure as defined by New
