PROTOCOL SUMMARY
Rationale
GSK1120212 is a potent, reversible and highly selective inhibitor of MEK1/MEK2 
activation and kinase activity.  This multicenter, non-randomized, open-label rollover 
study will provide continued access to GSK1120212 to subjects with solid tumors or 
leukemia who have previously participated in a GSK1120212 study and who are 
clinically benefitting from continued treatment and have an acceptable safety profile with 
GSK1120212.
Objectives
The primary objective of the study is to provide continued treatment with GSK1120212 
for subjects with solid tumors or leukemia who have previously participated in a 
GSK1120212 study and who are clinically benefitting from continued treatment and have 
an acceptable safety profile with GSK1120212.
Study Design
This Phase II, multicenter, non-randomized, open-label, rollover study is designed to 
provide continued access to GSK1120212 to subjects with solid tumors or leukemia who 
have previously participated in a GSK1120212 study (parent study) and who are 
clinically benefitting from continued treatment and have an acceptable safety profile with 
GSK1120212.  Subjects will be enrolled into the appropriate cohort based upon the 
treatment received in their parent study.  Enrollment into this study will be dependent 
upon the site’s agreement to participate in this study.  It is estimated that approximately 
250 subjects will be enrolled in this study. Subjects may continue treatment in the 
rollover study until no longer clinically benefitting, unacceptable toxicity, withdrawal of 
consent, or have access to local commercial supply of GSK1120212.
Study Assessments
Safety will be evaluated through routine physical examinations, vital sign measurements, 
12-lead electrocardiograms, echocardiograms or multiple-gated acquisition scans, clinical 
laboratory tests, and monitoring of adverse events.  Additional safety assessments may be 
necessary if a combination treatment regimen is administered to address specific safety 
concerns with the other agent(s) being administered.
Assessment of clinical activity will be performed throughout the study using local 
standard of care imaging practices and the appropriate assessment criteria as determined 
by the investigator to determine continued study participation and treatment with 
GSK1120212.  Only subjects considered by the investigator to be receiving clinical 
benefit may continue on study treatment.

INTRODUCTION
1.1.
Background
The RAS/RAF/MEK/ERK or MAPK pathway is a critical signal transduction cascade 
implicated in the uncontrolled proliferation of many human cancers.  Multiple genetic 
alterations in components of this cascade resulting in constitutive pathway activation 
have been well characterized over the past several decades [Davies, 2002; Allen, 2003].   
Given the critical location of MEK in this signalling pathway, it has been recognized as 
an important target for anti-cancer therapy.  Drug development efforts to inhibit MEK 
demonstrated clinical benefit, although with limited success.  For example, PD-0325901, 
CI-1040, and AZD6244, have achieved objective responses in melanoma, pancreatic 
cancer, and non-small cell lung cancer [LoRusso, 2010; LoRusso, 2005; 
GlaxoSmithKline Document Number RM2007/00642/03; Tzekova, 2008], but none have 
demonstrated significant single-agent activity in these tumor types. 
GSK1120212 is a potent, reversible, highly selective allosteric inhibitor of MEK1/MEK2 
activation and kinase activity.  The specificity of GSK1120212 to MEK1 and MEK2 
was confirmed against a large panel of kinases and no significant inhibitory activity 
was measured. A detailed summary of in vitro and in vivo non-clinical pharmacology 
studies is provided in the GSK1120212 Investigator Brochure (IB) 
[GlaxoSmithKline Document Number HM2009/00151/02].
As of 14 April 2011, 657 subjects with cancer have received at least one dose of 
GSK1120212 in 14 ongoing Phase I/II/III clinical studies.  Six of the 14 studies 
administer GSK1120212 as monotherapy, whereas the other 8 studies are designed 
to administer GSK112012 as combination therapy.  As of 14 April 2011, 206 
subjects in MEK111054, the first-time-in-human (FTIH) study of GSK1120212, had 
been dosed with GSK1120212.  Dose-related MAP kinase inhibition was 
demonstrated between daily doses of 0.5 and 2.0 mg with immunohistochemistry on 
tumor biopsies.  Modulation of MAP kinase pathways was consistent with changes 
observed with fluorodeoxyglucose-positron emission tomography imaging.  Based 
on the AEs observed in the FTIH MEK111054 study, the maximum tolerated dose 
(MTD) was determined to be 3.0 mg once-daily and the recommended Phase II dose 
(RP2D) of GSK1120212 was identified as 2.0 mg once-daily.  An unconfirmed 
response rate of 43% (6 out of 14 subjects) had an objective response, including 
2 complete responses (CRs) was observed.    The recommended monotherapy dose 
(2 mg once-daily) was well-tolerated.  Most notable adverse events (AEs) at this dose 
(n = 96) included class effects of rash (78%; 4% Grade 3) and diarrhea (54%; 1% 
Grade 3).  In all subjects dosed (n = 206), 5 cases of Grade 3 left ventricular systolic 
dysfunction, 3 cases of central serous retinopathy (CSR), and 1 case of retinal vein 
occlusion (RVO) were observed.  Among the 5 left ventricular ejection fraction 
(LVEF) cases, only 2 were considered related to study treatment and neither subject 
was symptomatic.  All 3 cases of CSR resolved upon study treatment interruption, 
and the subject with RVO has experienced significant improvement in visual acuity 
after intraocular bevacizumab treatments.

GSK1120212 is absorbed rapidly with median tmax generally occurring within 1 to 
3 hours after administration of GSK1120212.  After repeat dosing (Study Day 15), 
the mean area under the concentration-time curve (AUC(0-)) and maximum 
observed concentrations (Cmax) increased in a dose proportional manner (i.e., a 
2-fold increase in dose resulted in a 2-fold increase in exposure).  Between-subject 
variability (CV%) in exposure ranged from 27 to 50% for Cmax and 20 to 41% for 
area under the concentration-time curve from time zero (pre-dose) to 24 hrs after 
the last dose of study treatment (AUC(0-24)) across all dosing regimens.  
GSK1120212 accumulates with repeat dose with an effective half-life (t1/2) of 
approximately 5 days.
Further information on the safety, PK, and efficacy is described in the IB for 
GSK1120212 [GlaxoSmithKline Document Number HM2009/00151/02].
1.2.
Summary of Risk Management
The assessment of the risk of GSK1120212 is based on clinical data from the 
ongoing FTIH study in which subjects have been dosed daily for >21 days, as well as 
preclinical toxicity data.  In study MEK111054, the most common AEs experienced 
by 20% of all subjects with daily dosing were rash, diarrhea, fatigue, nausea, 
peripheral edema, and vomiting.  Rash and diarrhea are common, class-effect 
toxicities for MEK inhibitors.  In addition, visual impairment and LVEF reduction, 
although observed at lower frequencies, are also considered class-effect toxicities as 
they have been observed with GSK1120212 as well as other MEK inhibitors.  
Systemic toxicity of GSK1120212 has been evaluated following oral dosing in rats 
and dogs for up to 13 weeks.  In the most sensitive non-clinical species, rat, the 
principal adverse effects seen in oral toxicity studies of up to 13 weeks with daily 
dosing were skin and stomach erosions, skin ulcerations, which were secondary to 
reduced proliferation, altered phosphate homeostasis that resulted in soft tissue 
mineralization, hepatocellular necrosis, bone marrow degeneration/necrosis and 
ovarian perturbations.  The skin and stomach findings and phosphatemia 
demonstrated reversibility with 4 weeks of recovery.  Additional details are 
provided in the IB for GSK1120212 [GlaxoSmithKline Document Number 
HM2009/00151/02].
Procedures to minimize or monitor potential risks are listed below:

To reduce the risk of ocular toxicity, subjects with history of RVO, or CSR, 
subjects with predisposing factors for RVO or CSR or predisposing retinal 
pathology as determined by ophthalmologic exams are excluded.  
Ophthalmologic exams will be performed at baseline and as clinically 
warranted.

To monitor cardiac function, echocardiogram (ECHO) or multigated 
acquisition (MUGA) scans will be performed.

To reduce the risk of excessive gastrointestinal (GI) toxicity (diarrhea) and 
cutaneous toxicity (rash), subjects will be monitored closely and supportive 
care guidelines will be implemented.

Study Rationale
This open-label rollover study will permit subjects with solid tumors or leukemia, who 
are currently receiving GSK1120212 either as monotherapy or as part of a combination 
regimen in a GSK1120212 study that has met its study objective(s), to continue receiving 
treatment with GSK1120212.  In addition, this study will continue to collect safety 
information. Subject may continue treatment in this study if they are demonstrating 
clinical benefit as well as an acceptable safety profile with GSK1120212.
2.
OBJECTIVE
2.1.
Primary
The primary objective of the study is to provide continued treatment with GSK1120212 
for subjects who have previously participated in a GSK1120212 study and who continue 
to receive clinical benefit as well as have an acceptable safety profile with GSK1120212.
3.
STUDY DESIGN
This Phase II, multicenter, non-randomized, open-label, rollover study is designed to 
provide continued access to GSK1120212 to subjects who have previously participated in 
a GSK1120212 study (parent study).  All subjects enrolling in this study must be
receiving clinical benefit from continued treatment as well as have an acceptable safety 
profile with GSK1120212 to be eligible.  Subjects will be stratified into the appropriate 
cohort (see Section 3.1) based upon the treatment received in their parent study.  
Enrollment into this study will be dependent upon the site’s agreement to participate in 
this study.
Subjects must provide written informed consent prior to any study-related assessment or 
procedure being performed or treatment with GSK1120212 for this study.  After 
informed consent is obtained, subjects will be evaluated for study eligibility.
Protocol waivers or exemptions are not allowed.  Therefore, adherence to the study 
design requirements, including those specified in Appendix 1: Time and Events Table for 
Cohort A or Appendix 2: Time and Events Table for Cohort B, is essential.
The study will consist of a transition visit, continuous dosing treatment period, and a final 
study visit. 
Safety assessments will be performed throughout the study including the evaluation of 
physical examinations, vital sign measurements (blood pressure [BP], pulse rate, and 
temperature), 12-lead electrocardiograms (ECGs), echocardiograms (ECHOs) or MUGA 
scans, clinical laboratory assessments, and monitoring of AEs.  Additional safety 
assessments may be necessary if a combination treatment regimen is administered to 
address specific safety concerns with the other agent(s).

Assessment of clinical activity will be performed using local standard of care imaging 
practices and the appropriate assessment criteria (e.g. Response Evaluation Criteria in 
Solid Tumors [RECIST] 1.1) as determined by the investigator to determine continued 
study participation and treatment with GSK1120212.  Only subjects who continue to 
receive clinical benefit as determined by the investigator as well as having an acceptable 
toxicity safety profile will be allowed to continue treatment on study.
Subjects may continue treatment in this rollover study until lack of clinical benefit,
unacceptable toxicity, withdrawal of consent, or have access to local commercial supply 
of GSK1120212.
Refer to Appendix 1: Time and Events Table for Cohort A or Appendix 2: Time and 
Events Table for Cohort B for timing of all assessments.
NOTE:  Subjects participating in a BRAF/MEK combination study (receiving 
GSK1120212 in combination with GSK2118436 [a BRAF inhibitor]) should continue 
treatment in the GSK2118436 rollover study, BRF114144.
Supplementary study conduct information not mandated to be present in this protocol is 
provided in the accompanying study procedures manual (SPM).  The SPM will provide 
the site personnel with administrative and detailed technical information that does not 
impact subject safety.
3.1.
Cohorts
Cohort A:
Cohort A will consist of subjects who have completed <24 weeks of treatment with 
GSK1120212 monotherapy during their participation in the parent study.  It is anticipated 
that subjects in this cohort will have participated in a clinical pharmacology or another 
short-term study of GSK1120212.  Subjects will complete the Transition Visit and return 
for their next scheduled visit (Study Week 4), and then every 4 weeks thereafter.  
Subjects who have tolerated therapy well with limited toxicities and remain on study 
treatment >52 weeks may have the frequency of their interim visits decreased with 
approval and direction from the GSK Medical Monitor.
Subjects will receive GSK1120212 as an oral, daily dose of 2 mg or less.  Protocol 
specified guidelines for dose modifications and treatment discontinuation criteria are 
provided in Section 5.6 and Section 5.7, respectively.  If there are any uncertainties about 
the dose to be administered in this study, the GSK Medical Monitor should be consulted.  
Once treatment with GSK1120212 is discontinued the subject is to be withdrawn from 
the rollover study.
Cohort B:
Cohort B will consist of subjects who have completed 24 weeks of treatment with 
GSK1120212 (either as monotherapy or combination therapy with an approved anti-
cancer agent) during their participation in the parent study.  Subjects who transition from 
a combination study may continue to receive GSK1120212 in combination with the 
approved anti-cancer agent defined by the parent study or if, in the opinion of the 

RM2010/00127/07

26
investigator, the subject has received maximum benefit or is experiencing unacceptable 
toxicity from the approved anti-cancer agent, then treatment with the approved anti-
cancer agent may be discontinued and the subject may remain on study for continued 
treatment with GSK1120212 alone.  Once treatment with GSK1120212 is discontinued 
the subject is to be withdrawn from the rollover study.
Subjects will complete the Transition Visit assessments and then return for their next 
scheduled visit (Study Week 3 or 4), then every 3 or 4 weeks thereafter (depending on the 
schedule used in the parent study).  Subjects who have tolerated therapy well with 
limited toxicities and remain on study treatment >52 weeks may have the frequency of 
their interim visits decreased with approval and direction from the GSK Medical 
Monitor.  
All subjects will receive GSK1120212 at the current dose level administered in the parent 
study at the time of the Transition Visit.  If this starting dose of GSK1120212 is below 
the recommended Phase 2 dose (RP2D) previously defined for the given treatment 
regimen (e.g., dose modification following recovery from toxicity), the investigator, after 
consultation with the GSK Medical Monitor, may consider escalating the dose to the 
RP2D.  If there are any uncertainties about the dose(s) to be administered in this study, 
the GSK Medical Monitor should be consulted.
3.2.
Discussion of Design
The purpose of this study is to allow for continued treatment with GSK1120212 in 
subjects with solid tumors or leukemia who have participated in a GSK1120212 study of 
GSK1120212 and meet the protocol requirements for transitioning to the rollover study.  
Subjects will be closely monitored for known dose-limiting toxicities associated with 
GSK1120212.  The schedule of assessments and procedures to be performed during this 
study is provided in Appendix 1: Time and Events Table for Cohort A and Appendix 2: 
Time and Events Table for Cohort B.  To manage known side effects, and unless 
otherwise stated, supportive care therapies, such as growth colony stimulating factors, 
will be allowed and dosed in accordance with local institutional practices.  The details 
regarding dose modifications of GSK1120212 and guidance on additional assessments 
and procedures following events of special interest can be found in Section 5.6 and 
Section 5.7, respectively.
3.2.1.
Dose Rationale
For this study, the dose of study treatment to be administered to subjects will be 
individualized based upon the dose/regimen received during their participation in the 
parent study at the time of transition to the rollover study.  
1.
Subjects who have received <24 weeks of GSK1120212 monotherapy in the parent 
study (Cohort A) will receive the same continuous dosing regimen of GSK1120212 
at completion of the parent study. Subjects must be at a starting dose of 2 mg or less 
once-daily in the rollover study. 

RM2010/00127/07
CONFIDENTIAL
MEK114375
27
Dose selection for Cohort A was based on the preliminary results from the first-time-
in-human trial, MEK111054 [GlaxoSmithKline Document Number 
RM2007/00642/03].  Based on the preliminary AEs observed and protocol-defined 
dose-finding criteria in MEK111054, the single-agent maximum tolerated dose 
(MTD) was established at 3 mg once-daily, and the current recommended Phase II 
dose as monotherapy is 2 mg once-daily.
2.
Subjects who have received 24 weeks of continuous treatment with GSK1120212
as monotherapy or combination therapy with another approved anti-cancer agent 
(Cohort B) will continue treatment in the rollover study at the current dose level 
administered in the parent study at the time of transition to the rollover study.  If a 
subject required a dose modification while receiving treatment in the parent study, 
the subject will enter the rollover study and continue treatment on the modified dose 
unless after consultation with the GSK Medical Monitor it is appropriate to escalate 
the dose.

Permanent Discontinuation from Study Treatment and Subject 
Completion Criteria
4.1.4.1.
Permanent Discontinuation from Study Treatment
Subjects will receive study treatment until death or unacceptable AE, including meeting 
stopping criteria for liver chemistry defined in Section 5.7.4 or for hematologic and other 
non-hematologic toxicity.  In addition, study treatment may be permanently discontinued 
for any of the following reasons:

Deviation(s) from the protocol

Clinically significant AE leading to interruption of treatment for 
>21 consecutive days.  
NOTE:  If the investigator and GSK Medical Monitor agree that continued 
treatment will benefit the subject, then the subject may continue treatment, with 
or without a dose reduction, with the approval of the GSK Medical Monitor.

Disease progression (including death due to disease progression)

Request of the subject or proxy (withdrawal of consent by the subject)

Investigator’s discretion

Subject is lost to follow-up

Study is closed or terminated (such as when GSK1120212 becomes locally 
available as commercial product to the subject for continued treatment)
The primary reason study treatment was permanently discontinued must be documented 
in the subject’s medical records and electronic case report form (eCRF).
Once a subject has permanently discontinued from GSK1120212, the subject will not be 
allowed to be retreated.
All subjects who discontinue study treatment will have safety assessments performed at 
the Final Study Visit within approximately 28 days (7 days) of last dose of study 
treatment(s) as specified in Appendix 1: Time and Events Table for Cohort A or 
Appendix 2: Time and Events Table for Cohort B.
If the subject withdraws consent for further study treatment, a Final Study Visit should be 
completed (see Appendix 1: Time and Events Table for Cohort A or Appendix 2: Time 
and Events Table for Cohort B).  If the subject withdraws consent for further treatment 
and data collection, then no additional study visits or data collection should occur.
If the subject discontinues from treatment due to toxicity, ‘AE’ will be recorded as the 
primary reason for permanent discontinuation in the eCRF.

In the event that a subject is prematurely discontinued from the study at any time due to 
an AE (as defined in Section 8.5.1, “Definition of an AE”) or serious AE (SAE) (as 
defined in Section 8.5.2, “Definition of a SAE”), the procedures stated in Section 8.5, 
(“Adverse Events”) must be followed.  All subjects who have a Grade 3 or 4 clinical or 
laboratory abnormality at the time of withdrawal from the study must be followed until 
resolution to Grade 2 or less, unless it is unlikely to improve because of underlying 
disease.
If the subject discontinues from study treatment due to disease progression, ‘Disease 
Progression’ will be recorded as the primary reason for permanent study treatment 
discontinuation in the eCRF.
If the subject discontinues study treatment due to death, ‘Death’ will be recorded as the 
primary reason for permanent study treatment discontinuation in the eCRF.  The cause of 
death should also be documented in the eCRF
4.1.4.2.
Subject Completion Criteria
A subject will be considered to have completed the study if the subject progresses during 
study treatment or at the Final Study Visit, or dies.
A subject will be considered to have withdrawn from the study if the subject has not died 
or progressed and is lost to follow-up, has withdrawn consent, or at the investigator’s 
discretion is no longer being followed. 
The end of study is defined as the last subject, last visit.
5.
STUDY TREATMENTS
The term ‘study treatment’ is used throughout the protocol to describe any combination 
of products received by the subject as per the protocol design. Study treatment may 
therefore refer to the individual study treatments or the combination of those study 
treatments.

treatment may be contributing to the treatment-emergent toxicity and make the 
appropriate dosing adjustments, which may include reducing the dose of 1 or all study 
treatments.
Guidelines for GSK1120212 dose modifications are provided below.  Investigators 
should also refer to the GSK1120212 IB [GlaxoSmithKline Document Number 
HM2009/00151/02] or the prescribing information for the appropriate approved anti-
cancer combination agent for detailed information regarding warnings, precautions, 
contraindications, AEs, and recommendations for supportive care in the event of drug-
related toxicity. 
5.6.1.
GSK1120212 Dose Modification
For clinically significant toxicities that are considered related to GSK1120212 (i.e., 
diarrhea, peripheral and periorbital edema), except for rash (Section 5.7.1), ejection 
fraction changes (Section 5.7.8.1), pneumonitis (Section 5.7.4), or visual changes 
(Section 5.7.5), the dose modification guidelines for GSK1120212 are provided in Table

administered in the parent study.  Any dose modification(s) required while on study 
should be made according to the administration and/or dose modification guidelines 
presented in the protocol of the parent study or in the package insert for the agent, 
whichever is appropriate.  If, in the opinion of the investigator, the subject has received 
maximum benefit from the additional approved anti-cancer agent(s), then treatment with 
the approved anti-cancer agent(s) may be discontinued.
5.7.
Guidelines for Events of Special Interest
The severity of AEs will be graded utilizing the NCI-CTCAE, version 4.0
[NCI, 2009].  Guidelines for dose modifications and interruptions for management of 
common toxicities associated with the study treatment are provided in this section. 
5.7.1.
Monitoring and Management of Hypertension
5.7.1.1.
Monitoring of Hypertension
All BP assessments should be performed under optimal conditions i.e. after (1) 
subject has been seated with back support, ensuring that legs are uncrossed and flat 
on the floor, (2) subject is relaxed comfortably for at least 5 minutes, (3) 
preparatory steps including removal of any restrictive clothing over the cuff area 
and selection of the proper cuff size have been ensured, (4) the arm is supported so 
that the middle of the cuff is at the heart level, and (5) the subject remains quiet 
during the measurement.  In subjects with an initial BP reading within the 
hypertensive range, a second reading should be taken at least 1 minute later, with 
the 2 readings averaged to obtain a final BP measurement. 
Persistent hypertension is defined as an increase of systolic blood pressure (SBP) 
>140 mm Hg and/or diastolic blood pressure (DBP) >90 mmHg in up to 3 
subsequent visits with BP assessments from 2 readings under the optimal conditions 
described above.  Visits to monitor increased BP should be scheduled independently 
from the per-protocol visits outlined in the time-and-events schedule; ideally, 
subsequent BP assessments should be performed within 7 days.
Asymptomatic hypertension is defined as an increase of SBP >140 mmHg and/or 
DBP > 90 mmHg in the absence of headache, light-headedness, vertigo, tinnitus, 
episodes of fainting or other symptoms indicative of hypertension which would 
disappear after the BP is controlled within the normal range. 
5.7.1.2.
Management of Hypertension
For subjects experiencing an increase in SBP and/or DBP that is persistent and may 
be associated with the study treatment, recommendations for the clinical 
management of hypertension are described below:

Management of Dermatological AEs
5.7.2.1.
Supportive Measures for Rash
General considerations in rash management:

Encourage subjects to avoid unnecessary exposure to sunlight.

RM2010/00127/07
CONFIDENTIAL
MEK114375
36

Employ a proactive approach (i.e., prophylactic treatment; see below for 
recommendations).

If a subject develops rash, verify treatment intervention and follow steps 
outlined under “Reactive Management”.
5.7.2.2.
Prophylactic Treatment of Rash
The exact prophylactic regimen should be based on the investigator’s experience; 
however, the following regimen is recommended: 

Broad-spectrum sunscreen (containing titanium dioxide or zinc oxide) with an 
skin protection factor (SPF) ≥15;

Thick, alcohol-free emollient cream (e.g. glycerine and cetomacrogel cream) on 
dry areas of the body;

Mild topical steroid (1% hydrocortisone cream), with escalation to higher 
strength and/or oral steroid as detailed below.

Offer topical antibiotics or oral doxycycline 100 mg twice daily (BID) or oral 
minocycline 100 mg BID for the first 2 to 3 weeks of GSK1120212 
administration.  
Topical agents should be applied on a daily basis starting on Study Day 1 of study 
treatment, and more often as needed.  Oral antibiotics should be started on Study Day 1.
5.7.2.3.
Reactive Management of Rash
It is strongly recommended that subjects who develop dermatological reactions receive 
evaluations for management on the specific side effect. 

For pruritic lesions, the use of cool compresses and oral antihistamine agents 
may be helpful.  

For fissuring, the use of Monsel’s solution, silver nitrate, or zinc oxide cream is 
advised.  

For desquamation, thick emollients and mild soap are recommended.  

For paronychia, antiseptic bath and local potent corticosteroids in addition to 
oral antibiotics are recommended and, if no improvement is seen, a dermatology 
or surgery consultation is recommended.  

For infected lesions, bacterial and fungal culturing followed by the appropriate 
culture-driven systemic or topical antibiotics is indicated.
Consider the following algorithm in a stepwise manner (Table 3).

Management of Diarrhea
General considerations for diarrhea management:
Rule out other or concomitant causes.  These include medications (e.g., stool softeners, 
laxatives, antacids, etc), infection by C. difficile or Candida species, partial bowel 
obstruction, malabsorption/lactose intolerance, fecal impaction, diets high in fiber or 
lactose.
For uncomplicated Grade 1 to 2 diarrhea (i.e., mild to moderate defined as 
NCI-CTCAE [NCI, 2009] Grade 1 or 2 with no complicating signs or symptoms):

Administer standard dose of loperamide:

Initial dose of 4 mg followed by 2 mg every 4 hours or after every 
unformed stool; maximum of 16 mg (8 tablets) per day.

Continuation of loperamide is suggested until diarrhea-free for 12 hours

Dietary modifications: stop all lactose containing products and eat small meals. 
A BRAT (banana, rice, apples, toast) diet may be helpful.

Hydration: drink 8 to 10 large glasses of clear liquids per day (e.g., Gatorade or 
broth)

Consider a temporary GSK1120212 dose interruption until symptoms have 
resolved to baseline or Grade 1.  Re-treatment with GSK1120212 may then be 
resumed at 100% of current dose level.

If mild to moderate diarrhea persists for >24 hours, administer loperamide 2 mg 
every 2 hours; maximum 16 mg (8 tablets) per day.  Consider adding oral 
antibiotics.

If mild to moderate diarrhea persists after 48 hours total treatment with 
loperamide, start second-line agents (octreotide, budesonide or tincture of 
opium).  Consider adding oral antibiotics.
Grade 3 to 4 diarrhea or complicated Grade 1 to 2 diarrhea (i.e., cramping, 
nausea/vomiting ≥Grade 2, decreased performance status, fever, sepsis, Grade 3 or 4 
neutropenia, frank bleeding and/or dehydration):

Subject must call the investigator immediately for any complicated severe 
diarrhea event.

Discontinue GSK1120212 treatment and hold until symptoms resolve to 
Grade 1 or baseline.  Consider re-starting therapy at a reduced dose level.

If loperamide has not been initiated, initiate loperamide immediately.  Initial 
dose 4 mg followed by 2 mg every 2 hours or after every unformed stool; 
maximum of 16 mg (8 tablets) per day.

For dehydration, use IV fluids as appropriate; if severe dehydration, administer 
octreotide.

RM2010/00127/07
CONFIDENTIAL
MEK114375
39

Administer antibiotics as needed (e.g. fluoroquinolones), especially if diarrhea is 
persistent beyond 24 hours or there is fever or Grade 3 or 4 neutropenia.

Intervention should be continued until the subject is diarrhea free for at least 
24 hours.
Intervention may require hospitalization for subjects most at risk for life-threatening 
complications.
5.7.4.
Management of Pneumonitis
To reduce the risk of pneumonitis, subjects will be monitored closely for symptoms, 
evaluated with imaging and/or functional studies, and stopping/interruption criteria will 
be implemented.  Dose modification and supportive care guidelines for pneumonitis will 
also be implemented.

Stopping Criteria for Visual Changes
Episodes of visual changes have been observed in subjects receiving trametinib, and 
ocular adverse events are known to be related to trametinib. An ophthalmologist 
should be consulted if changes in vision develop.  If the visual changes are clearly 
unrelated to study treatment (e.g., allergic conjunctivitis), then monitor closely as it 
may be reasonable to defer ophthalmic examination. Special attention should be 
given to retinal findings (e.g., retinal pigment epithelial detachment (RPED) or 
retinovascular abnormalities (i.e., branch or central retinal vein occlusions (RVO)).  
For events of visual changes (regardless of severity) for which an ophthalmic 
examination is conducted, a blood sample for PK analysis must be drawn as close as 
possible to the time of the event.
Visual change events should be graded using Table 7 based on the NCI-CTCAE, version 
4.0 [NCI, 2009]).
Table 7
Grading of Visual Changes
Grade
Description
1
Asymptomatic or symptomatic but not limiting activities of daily living (ADL); clinical or 
diagnostic observations only; intervention not indicated
2
Symptomatic with moderate decrease in visual acuity (20/40 or better); limiting instrumental 
ADL;  local or non-invasive intervention indicated (e.g., topical or oral agents)
3
Symptomatic with marked decrease in visual acuity or marked visual field defect (worse than 
20/40 but better than 20/200 in the affected eye); Severe pain or medically significant but not 
immediately sight-threatening; operative intervention indicated; disabling; limiting self care ADL
4
Sight-threatening consequences; urgent intervention indicated; blindness (20/200 or worse) in 
the affected eye
Grade 1 visual changes:

For Grade 1 visual changes that do not affect vision and which, in the option of 
the treating physician, are clearly unrelated to study treatment (e.g., 
conjunctivitis), treatment with GSK1120212 may continue with close 
observation.

If attribution to study treatment is unclear, immediately refer the subject for 
ophthalmic exam; if a dilated fundus examination cannot be performed 
within 7 days of onset, interrupt treatment with GSK1120212 until RPED 
and RVO can be excluded by retina specialist/ophthalmologist. Follow the 
guidance below depending on the results.
If a retinal abnormality is noted, interrupt treatment with GSK1120212 
immediately and referral to a retinal specialist should be considered for further 
evaluation.
  If RPED suspected or diagnosed (asymptomatic; clinical or diagnostic 
observations only) continued treatment with retinal evaluation   monthly 
until resolved.  Report as an SAE.  If worsens see grade 2-3 guidance.

RM2010/00127/07
CONFIDENTIAL
MEK114375
44

If RVO is diagnosed, report as a SAE and permanently discontinue 
treatment with GSK1120212

If there is no evidence of RPED or RVO, resume treatment with GSK1120212 
at the same dose level.
Grade 2 or Grade 3 visual changes:

Immediately interrupt treatment with GSK1120212 and refer subject to an 
ophthalmologist for evaluation with an ophthalmic exam.  For all subjects with 
findings consistent with RPED or RVO based on the ophthalmic exam, referral 
to retinal specialist, if available, should be considered for further evaluation.

If RVO is diagnosed report as a SAE and permanently discontinue 
GSK1120212

If RPED is diagnosed (symptomatic with mild to moderate decrease in 
visual acuity; limiting instrumental ADL, perform retinal evaluation 
monthly and if improves to ≤ Grade 1, resume treatment with 
GSK1120212 at lower dose (reduced by 0.5 mg) or discontinue in 
subjects taking GSK1120212 1 mg daily.

If RPED and RVO are excluded and visual changes are clearly 
unrelated to study treatment, restart GSK1120212 at the same dose 
level.
Grade 4 visual changes:

Interrupt GSK1120212, consult ophthalmologist immediately and report as 
SAE.

If RPED and RVO are excluded, may consider restarting GSK1120212 at 
same or reduced dose after discussion with the study medical monitor

If RPED or RVO diagnosed permanently discontinue treatment with 
GSK1120212.

Liver Chemistry Stopping Criteria
Phase II liver chemistry stopping and follow-up criteria have been designed to assure 
subject safety and evaluate liver event etiology in alignment with the United States Food 
and Drug Administration (US FDA) premarketing clinical liver safety guidance.  Phase II 
liver chemistry stopping criteria 1 to 5 are defined as follows:
1. Alanine aminotransferase (ALT) 3 times upper limit of normal (ULN) and

NOTE: If serum bilirubin fractionation is not immediately available, study 
treatment(s) should be discontinued if ALT 3 times ULN and bilirubin 2 times 
ULN.  Serum bilirubin fractionation should be performed if testing is available.  If 
testing is unavailable, record presence of detectable urinary bilirubin on dipstick, 
indicating direct bilirubin elevations and suggesting liver injury.
2. ALT 5 times ULN.
3. ALT 3 times ULN if associated with the appearance or worsening of symptoms 
of hepatitis or hypersensitivity such as fatigue, nausea, vomiting, right upper 
quadrant pain or tenderness, fever, rash or eosinophilia.

Refer to Appendix 4 for algorithm of liver chemistry stopping and follow-up criteria.
5.7.7.
QTc Withdrawal Criteria
QTc should be assessed at the frequency shown in Appendix 1: Time and Events Table 
for Cohort A or Appendix 2: Time and Events Table for Cohort B.
A subject who experiences a QTc prolongation1 defined as QTcB ≥501 msec or 
uncorrected QT>600 msec or (QTcB>530  msec or QTcB>530 msec for subjects 
with bundle branch block will have study treatment with GSK1120212 withheld:
1 based on average QTc value of triplicate ECGs (confirmed via manual over-read).  For example, if an 
ECG demonstrates a prolonged QT interval, obtain 2 more ECGs over a brief period, and then use the 
averaged QTc values of the 3 ECGs to determine whether the subjects should have study treatment 
withheld.

RM2010/00127/07
CONFIDENTIAL
MEK114375
48
If the QTc prolongation resolves to grade 1 (450 - 480 msec) or baseline, the subject 
may be re-started on the study treatment at current dose level if the investigator and 
GSK Medical Monitor agree that the subject will benefit from further treatment.  If the 
event does not resolve or recurs, permanently discontinue study treatment.
5.7.7.1.
French and the United Kingdom Specific QTc Stopping Criteria
In line with local requirements, a subject in France or the United Kingdom that meets 
the QTc1 criteria below will have study treatment withheld:
QTcB >500 msec
1Based on average QTc value of triplicate ECGs to include manual over-read.  For example, if an ECG 
demonstrates a prolonged QT interval, obtain 2 more ECGs over a brief period, and then use the 
averaged QTc values of the 3 ECGs to determine whether the subjects should have study treatment 
withheld.
If the QTc prolongation resolves to Grade 1 or baseline, the subject may be re-started on 
the study treatment if the investigator and GSK Medical Monitor agree that the subject 
will benefit from further treatment.
5.7.8.
Criteria for Evaluating Cardiac Function and Electrical Activity
5.7.8.1.
Left Ventricular Ejection Fraction Stopping Criteria
ECHO or MUGA scans should include an evaluation for LVEF and both right- and left-
sided valvular lesions.  For each subject, the same procedure should be performed at the 
time of transition and at the Final Study Visit to allow direct comparison.  Additional 
ECHO assessments may be performed if clinically warranted.
Subject who have an asymptomatic, absolute decrease of >10% in LVEF compared with 
baseline (baseline value from parent study) and the ejection fraction is below the 
institution’s LLN should have treatment with GSK1120212 withheld and a repeat 
evaluation of LVEF within 2 weeks.  

If the LVEF recovers (defined as LLN and absolute decrease 10% compared 
with baseline [baseline value from parent study]) at any time during the next 
4 weeks, after consultation and approval of the GSK Medical Monitor, the 
subject may be restarted on GSK1120212 at a reduced dose.  For such subjects, 
monitoring of LVEF will be performed 2 and 4 weeks after rechallenge, and 
every 4 weeks thereafter for 12 weeks, and then per protocol.

If repeat LVEF does not recover within 4 weeks, treatment with GSK1120212 
should be permanently discontinued and have a cardiology consult.  Ejection 
fraction should be monitored in 2 weeks and then every 4 weeks for a total of 16 
weeks or until resolution.

CONFIDENTIAL
MEK114375
49
Subjects with symptomatic Grade 3 (resting LVEF 39-20% or >20% absolute 
reduction from baseline) or symptomatic Grade 4 (resting LVEF <20%) left 
ventricular systolic dysfunction must discontinue treatment with GSK1120212 and have 
a cardiology consult. Ejection fraction should be monitored at 2 weeks, at 4 weeks, and 
then every 4 weeks for a total of 16 weeks or until resolution.  Symptomatic Grade 3 
and symptomatic Grade 4 left ventricular systolic dysfunctions are to be reported as 
SAEs.
The same procedure (either ECHO or MUGA, although ECHO is preferred) should be 
performed at baseline and at follow-up visit(s).  Copies of all ECHOs and/or MUGA 
scans performed on subjects who experience an absolute decrease >10% in LVEF 
compared to baseline and LVEF <LLN (or <50% when LLN does not exist) will be 
required by GSK for review.  Instructions for submission of qualifying ECHOs/MUGA 
scans are provided in the SPM.

Treatment after Discontinuation of Study Treatment or 
Discontinuation from /Completion of Study
The investigator is responsible for ensuring that consideration has been given for the 
post-study care of the subject’s medical conditions whether or not GSK is providing 
specific post-study treatment.
Subjects will receive standard of care treatment as determined by their healthcare 
provider after withdrawal from this study.
Post-study treatment will not be provided as part of the protocol.  Upon discontinuation 
from assigned study treatment, subjects may receive additional (non-protocol) therapy at 
the discretion of the treating physician.  New therapy should be documented in the eCRF. 
Every effort should be made to complete the required post-treatment follow-up 
evaluations prior to initiating further anti-cancer therapy or dosing of an investigational 
agent (see Appendix 1: Time and Events Table for Cohort A or Appendix 2: Time and 
Events Table for Cohort B for Final Study Visit assessments and procedures).  
6.4.
Treatment of Study Treatment Overdose
6.4.1.
GSK1120212
In the event of a GSK1120212 overdose defined as administration of more than the 
highest dose administered in clinical studies to date, the investigator should contact the 
GSK Medical Monitor immediately and closely monitor the subject for AEs/SAEs and 
laboratory abnormalities.
Subjects suspected of overdose should be monitored until study treatment(s) can no 
longer be detected systemically (at least 7 days).
Decisions regarding dose interruptions or modifications will be made by the investigator 
in consultation with the GSK Medical Monitor based on the clinical evaluation of the 
subject.
A plasma sample for PK analysis may be requested by the GSK Medical Monitor on a 
case-by-case basis.  This plasma sample should be collected as soon as possible, but 
within 7 days from the date of the last dose of on-study dosing.

LIFESTYLE OR DIETARY RESTRICTIONS
7.1.
Meals and Dietary Restrictions
GSK1120212 should be administered with approximately 240 mL (8 fl oz) of water, 
under fasting conditions, either 1 hour before or 2 hours after a meal.
If diet recommendations change with emerging data (i.e. the planned food-effect study) 
formal documentation will be provided by GSK and stored in the study file.  Any such 
changes will be communicated to the investigative sites in the form of a letter without 
amendment to the protocol.
7.2.
Activity
Subjects should abstain from strenuous exercise for 48 hours prior to each blood 
collection for clinical laboratory tests.
7.3.
Contraception Requirements
7.3.1.
Female Subjects
Females of non-childbearing potential (i.e., physiologically incapable of becoming 
pregnant), as defined in the parent study, are any female who has had a documented 
hysterectomy, bilateral oophorectomy (ovariectomy), or bilateral tubal ligation; or post-
menopausal.
Female subjects of childbearing potential, as defined in the parent study and determined 
not to be post-menopausal, must continue to use the same adequate method of 
contraception as used in the parent study during the rollover study and for 4 months*
following the last dose of study treatment(s).
GSK acceptable contraceptive methods, when used consistently and in accordance with 
both the product label and the instructions of the physician, are as follows:

An intrauterine device with a documented failure rate of <1% per year

RM2010/00127/07
CONFIDENTIAL
MEK114375
54

Vasectomized partner who is sterile prior to the female subject’s entry in the 
study and is the sole sexual partner for that female.

Complete abstinence from sexual intercourse for 14 days prior to the first dose 
of study treatment, through the dosing period, and for at least 4 months* after
the last dose of study treatment

Double-barrier contraception: condom and occlusive cap (diaphragm or 
cervical/vault caps) with a vaginal spermicidal agent 
(foam/gel/cream/suppository).
NOTE:  Hormonal-based methods (e.g., oral contraceptives) are not permitted due 
to potential drug-drug interaction with GSK1120212.
*NOTE:  Contraception requirement may last for a time period longer than what is 
required for single-agent GSK1120212 since female subjects may be exposed to 
cytotoxic chemotherapy during study treatment.  Investigators should reference the 
product label for the appropriate chemotherapeutic agent(s) for additional 
clarification.
Refer to Section 8.5.5 for details on reporting any pregnancy that occurs during 
participation in the rollover study.

Approximately 3 teaspoons (15 mL) of blood will be collected at each study visit. The 
total amount of blood collected for the duration of the study is dependent on the length of 
individual subject participation in the study.
Investigators may be requested to perform additional safety tests during the course of the 
study based on newly available data to ensure appropriate safety monitoring.  
Appropriate local regulatory and ethical approvals should be obtained before any 
additional testing is performed.
If vital signs, ECGs and blood draws are scheduled for the same nominal time, the ECG 
will be obtained first, followed by the vital signs, and then blood draws.

NOTE:  Baseline will refer to time of first dose of study treatment(s) on the rollover 
study as baseline for some AEs may have occurred in parent study as AE continued at the 
time of transition to the rollover study).  This definition of baseline will be applicable to 
other assessments (i.e., physical examination findings, laboratory values) for this study 
when baseline reference is used.
8.4.1.
Physical Examinations
Complete physical examinations will be performed at the time points outlined in 
Appendix 1: Time and Events Table for Cohort A or Appendix 2: Time and Events Table 
for Cohort B.  Height and weight will also be measured and recorded at the initial 
physical examination only.
8.4.1.1.
Assessment of Skin Changes
All physical examinations should include examination of skin and assessment of any skin 
changes.  Post-baseline skin examinations by a referral dermatologist or other appropriate 
physician should be conducted if clinically indicated.  Biopsy of skin lesions related to 
treatment may be performed if clinically indicated.
8.4.2.
Ophthalmologic Examinations
All subjects transitioning to the rollover study are expected to have had a standard 
ophthalmic exam performed by an ophthalmologist during Screening in their parent 
study.  Ophthalmologic examinations will be conducted during the rollover study if 
clinically indicated (refer to Section 5.7.5 for stopping criteria for visual changes).  If an 
ophthalmologic examination is necessary, it should include dilated indirect fundoscopic 
examination, best corrected visual acuity, visual field examination, tonometry, slit lamp 
biomicroscopic examination and direct fundoscopy, with special attention to retinal 
abnormality. Optical coherence tomography is strongly recommended at scheduled 
visits, and if retinal abnormalities are suspected. Other types of ancillary testing 
including color fundus photography and fluorescein angiography are also 
recommended if clinically indicated.
8.4.3.
Vital Signs
Vital sign measurements (BP, temperature, respiratory rate, and pulse rate) will be taken 
at the time points outlined in Appendix 1: Time and Events Table for Cohort A or 
Appendix 2: Time and Events Table for Cohort B.  Vital signs will be measured more 
frequently if warranted by clinical condition of the subject.  Refer to the SPM for details 
regarding measurement of vital signs.
8.4.4.
Electrocardiograms
Single 12-lead ECGs will be obtained at each time point during the study according to 
Appendix 1: Time and Events Table for Cohort A or Appendix 2: Time and Events Table 
for Cohort B using an ECG machine that automatically calculates the heart rate and 
measures RR, PR, QRS, QT and QTc intervals.

If there are any clinically significant abnormalities including, but not limited to, 
QTcB >500 msec, confirm with 2 additional ECGs taken at least 5 minutes apart.
Refer to Section 5.7.7 for QTc withdrawal criteria and additional readings that may be 
necessary.  Refer to the SPM for details regarding ECG procedures.
8.4.5.
Echocardiograms/MUGA Scans
ECHO or MUGA scans (preferably ECHO) will be performed to assess cardiac ejection 
fraction and cardiac valve abnormalities at the time points specified in Appendix 1: Time 
and Events Table for Cohort A or Appendix 2: Time and Events Table for Cohort B.  The 
procedure (either ECHO or MUGA, although ECHO is preferred) to document the 
subject’s baseline LVEF status must be used consistently throughout the study. If 
possible, it is also preferred that interpretation of LVEF status be performed consistently 
by the same reviewer throughout the study.
Copies of all ECHOs and/or MUGA scans performed on subjects who experience an 
absolute >10% decrease in LVEF compared to baseline and LVEF <LLN will be required 
by GSK for review.  Instructions for submission of qualifying ECHOs/MUGA scans are 
provided in the SPM
Refer to Section 5.7.8.1 for details regarding LVEF evaluation.
8.4.6.
Clinical Laboratory Assessments
Clinical laboratory tests (Table 10) will be performed as outlined in Appendix 1: Time 
and Events Table for Cohort A or Appendix 2: Time and Events Table for Cohort B.  At 
the discretion of the investigator, additional laboratory samples may be taken as clinically 
necessary.
Whenever possible, every effort should be made to ensure that laboratory results 
submitted to GSK are from the designated central laboratory.  If laboratory assessments 
are performed at the institution’s local laboratory, please refer to the SPM for appropriate 
and handling of samples to avoid duplicate and/or additional blood draws.
All laboratory tests with values that are significantly abnormal during study participation 
or within 30 days after the last dose of study treatment(s) should be repeated until the 
values return to within normal range or baseline.  All subjects who have a Grade 3 or 4 
laboratory abnormality at time of study withdrawal must be followed until resolution to 
Grade 2 or less, unless it is unlikely to improve due to underlying disease.  If such values 
do not return to within normal range within a period judged reasonable by the 
investigator, the etiology should be identified and the GSK Medical Monitor notified.

Adverse Events
AEs and SAEs will be monitored from the time of consent until 30 days after the last 
dose of study treatment(s).  All AEs and SAEs must be recorded and reported as detailed 
in the following sections and in the SPM.  At the time of consent, all ongoing AEs that 
began during participation in the parent study must be recorded in the eCRF.
The investigator or site staff will be responsible for detecting, documenting and reporting 
events that meet the definition of an AE or SAE as outlined in Section 8.5.1 and 
Section 8.5.2, respectively.
8.5.1.
Definition of an AE
Any untoward medical occurrence in a subject or clinical investigation subject, 
temporally associated with the use of a medicinal product, whether or not considered 
related to the medicinal product.
Note: An AE can therefore be any unfavorable and unintended sign (including an 
abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally 
associated with the use of a medicinal product.  For marketed medicinal products, this 
also includes failure to produce expected benefits, abuse, or misuse. Examples of events 
meeting the definition of an AE include:

Exacerbation of a chronic or intermittent pre-existing condition including either an 
increase in frequency and/or grade of the condition

RM2010/00127/07
CONFIDENTIAL
MEK114375
61

New conditions detected or diagnosed after study treatment administration even 
though it may have been present prior to the start of the study

Signs, symptoms, or the clinical sequelae of a suspected interaction

Signs, symptoms, or the clinical sequelae of a suspected overdose of either study 
treatment or a concomitant medication (overdose per se will not be reported as an 
AE/SAE). 
Events that do not meet the definition of an AE include:

Medical or surgical procedure (e.g., endoscopy, appendectomy); the condition that 
leads to the procedure is an AE.

Situations where an untoward medical occurrence did not occur (social and/or 
convenience admission to a hospital).

Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) present 
or detected at the start of the study that do not worsen.

The disease/disorder being studied, or expected progression, signs, or symptoms of 
the disease/disorder being studied, unless more severe than expected for the subject’s 
condition.
8.5.2.
Definition of a SAE
A SAE is any untoward medical occurrence that, at any dose:
a.
Results in death
b.
Is life-threatening
NOTE:  The term 'life-threatening' in the definition of 'serious' refers to an event in 
which the subject was at risk of death at the time of the event.  It does not refer to an 
event, which hypothetically might have caused death, if it were more severe.
c.
Requires hospitalization or prolongation of existing hospitalization
NOTE:  In general, hospitalization signifies that the subject has been detained 
(usually involving at least an overnight stay) at the hospital or emergency ward for 
observation and/or treatment that would not have been appropriate in the physician’s 
office or outpatient setting. Complications that occur during hospitalization are AEs. 
If a complication prolongs hospitalization or fulfils any other serious criteria, the 
event is serious.  When in doubt as to whether “hospitalization” occurred or was 
necessary, the AE should be considered serious.
Hospitalization for elective treatment of a pre-existing condition that did not worsen 
from baseline is not considered an AE.
d.
Results in disability/incapacity, or

RM2010/00127/07
CONFIDENTIAL
MEK114375
62
NOTE:  The term disability means a substantial disruption of a person’s ability to 
conduct normal life functions.  This definition is not intended to include experiences 
of relatively minor medical significance such as uncomplicated headache, nausea, 
vomiting, diarrhea, influenza, and accidental trauma (e.g. sprained ankle) which may 
interfere or prevent everyday life functions but do not constitute a substantial 
disruption.
e.
Is a congenital anomaly/birth defect.
f.
Medical or scientific judgement should be exercised in deciding whether reporting is 
appropriate in other situations, such as important medical events that may not be 
immediately life-threatening or result in death or hospitalization but may jeopardize 
the subject or may require medical or surgical intervention to prevent one of the 
other outcomes listed in the above definition. These should also be considered 
serious. Examples of such events are invasive or malignant cancers, intensive 
treatment in an emergency room or at home for allergic bronchospasm, blood 
dyscrasias or convulsions that do not result in hospitalization, or development of 
drug dependency or drug abuse.
g.
All events of possible drug-induced liver injury with hyperbilirubinemia defined as 
ALT 3 times ULN and bilirubin 2 times ULN (>35% direct) (or ALT 3 times 
ULN and INR >1.5, if INR is measured) termed ‘Hy’s Law’ events (INR 
measurement is not required and the threshold value stated will not apply to subjects 
receiving anticoagulants.
NOTE: Bilirubin fractionation is performed if testing is available.  If testing is 
unavailable, record presence of detectable urinary bilirubin on dipstick indicating 
direct bilirubin elevations and suggesting liver injury.  If testing is unavailable and a 
subject meets the criterion of total bilirubin 2 times ULN, then the event is still 
reported as a SAE.  If INR is obtained, include values on the SAE form.  INR 
elevations >1.5 suggest severe liver injury
h.
Protocol-specific SAEs: LVEF meeting the stopping criteria (see Section 5.7.8).
i.
Additionally, new primary cancers and laboratory abnormalities as referenced in 
Section 8.5.3 are considered to be serious events by virtue of being medically 
important. These should be reported in the same manner as other SAEs.
8.5.3.
Laboratory and Other Safety Assessment Abnormalities 
Reported as AEs and SAEs
Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis), or 
other safety assessments (e.g., ECGs, radiological scans, vital signs measurements) 
including those that worsen from baseline, and events felt to be clinically significant in 
the medical and scientific judgment of the investigator are to be recorded as an AE or 
SAE, in accordance with the definitions provided.  
All events of possible drug-induced liver injury with hyperbilirubinemia (defined as ALT 
3 times ULN plus bilirubin 2 times ULN and/or INR >1.5) or Hy’s Law events, 
require immediate study treatment cessation and reporting as an SAE.

RM2010/00127/07
CONFIDENTIAL
MEK114375
63
NOTE: bilirubin fractionation is performed if testing is available. If testing is unavailable, 
record presence of detectable urinary bilirubin on dipstick indicating direct bilirubin 
elevations and suggesting liver injury.
If testing is unavailable and a subject meets the criterion of total bilirubin 2.0 times 
ULN, then the event is still reported as an SAE. If INR is obtained, include values on the 
SAE form. INR elevations >1.5 suggest severe liver injury.
In addition, an associated AE or SAE is to be recorded for any laboratory test result or 
other safety assessment that led to an intervention, including permanent discontinuation 
of study treatment, dose reduction, and/or dose interruption/delay.
Any new primary cancer must be reported as a SAE.
However, any clinically significant safety assessments that are associated with the 
underlying disease, unless judged by the investigator to be more severe than expected for 
the subject's condition, are not to be reported as AEs or SAEs.
8.5.3.1.
Disease-Related Events and/or Disease-Related Outcomes Not 
Qualifying as SAEs
An event which is part of the natural course of the disease under study (i.e., disease 
progression or hospitalization due to disease progression) does not need to be reported as 
an SAE. Death due to disease under study is to be recorded on the Death eCRF form.  
However, if the underlying disease (i.e., progression) is greater than that which would 
normally be expected for the subject, or if the investigator considers that there was a 
causal relationship between treatment with study treatment(s) or protocol 
design/procedures and the disease progression, then this must be reported as a SAE.
8.5.4.
Time Period and Frequency of Detecting AEs and SAEs
The investigator or site staff is responsible for detecting, documenting and reporting 
events that meet the definition of an AE or SAE.
AEs will be collected from the time the first dose of study treatment is administered until 
30 days following discontinuation of study treatment regardless of initiation of a new 
cancer therapy or transfer to hospice.
SAEs will be collected over the same time period as stated above for AEs.  In addition, 
any SAE assessed as related to study participation (e.g., protocol-mandated procedures, 
invasive tests, or change in existing therapy), study treatment or GSK concomitant 
medication must be recorded from the time a subject consents to participate in the study 
up to and including any follow-up contact. All SAEs will be reported to GSK within 
24 hours, as indicated in Section 8.5.4.1.
After discontinuation of study treatment, the investigator will monitor all AEs/SAEs that 
are ongoing until resolution or stabilization of the event or until the subject is lost to 
follow-up.  At any time after 30 days the investigator may report any AE that they 
believe possibly related to study treatment.

8.5.4.2.
Regulatory reporting requirements for SAEs
Prompt notification of SAEs by the investigator to GSK is essential so that legal 
obligations and ethical responsibilities towards the safety of subjects are met.
GSK has a legal responsibility to notify both the local regulatory authority and other 
regulatory agencies about the safety of a product under clinical investigation.  GSK will 
comply with country specific regulatory requirements relating to safety reporting to the 
regulatory authority, IRB/IEC and investigators.
Investigator safety reports are prepared for suspected unexpected serious adverse 
reactions according to local regulatory requirements and GSK policy and are forwarded 
to investigators as necessary.
An investigator who receives an investigator safety report describing a SAE(s) or other 
specific safety information (e.g. summary or listing of SAEs) from GSK will file it with 
the IB and will notify the IRB/IEC, if appropriate according to local requirements.
8.5.5.
Pregnancy
Any pregnancy that occurs during study participation must be reported using a clinical 
trial pregnancy form. To ensure subject safety, each pregnancy must be reported to GSK 
within 2 weeks of learning of its occurrence. The pregnancy must be followed to 
determine outcome (including premature termination) and status of mother and child.
Pregnancy complications and elective terminations for medical reasons must be reported 
as an AE or SAE. Spontaneous abortions must be reported as a SAE.
Any SAE occurring in association with a pregnancy brought to the investigator’s 
attention after the subject has completed the study and considered by the investigator as 
possibly related to the study treatment, must be promptly reported to GSK.
8.5.6.
Optional Tumor and/or Skin Biopsy and Biomarker Assessments
All sites are required to participate in the collection of tumor or skin biopsies and tumor 
marker sampling; however, participation by the individual subject is optional.  Samples 
will only be collected only from subjects who provide consent for tumor biopsy, skin 
biopsy and/or blood sampling for tumor marker assessment at the time of transition to 
this study.  If consent is provided, tumor tissue sample(s), skin sample(s), and/or blood 
samples (2 x 10 mL) will be collected at the time of disease progression.
Further details on tissue and/or blood requirements for specific tumor biopsy or tumor 
marker assessments will be provided in the SPM.
8.5.7.
Optional Tumor Biopsy
Some subjects may have had pre- and/or post-dose tumor biopsies collected during their 
participation in their parent study. However, an additional tumor tissue sample from a 

RM2010/00127/07
CONFIDENTIAL
MEK114375
66
lesion not required for disease assessment may be requested during this study.  Total 
mutations in BRAF, MEK1 or 2, PIK3Ca, PTEN and other genes may be assessed.
8.5.8.
Optional Skin Biopsy
Some subjects may have had skin biopsies collected during their participation in their 
parent study.  However, additional biopsy or initial biopsies in or around skin lesions that 
change on treatment may be taken during this study.  Testing of these biopsies may 
include analysis of proteins related to the action of GSK1120212.  Deoxyribonucleic acid 
(DNA) analysis of these biopsy specimens will be restricted to cancer-related genes.
8.5.9.
Optional Blood Sampling for Biomarker Analysis
In subjects whose disease may be followed by well-characterized tumor markers, 
assessment of clinical activity should include results of tumor marker measurements.
Blood samples may be collected for analysis of potential surrogate markers of 
GSK1120212 activity (e.g. interleukin-8) at the time of disease progression.  Additional 
blood proteins or tumor DNA related to the activity of GSK1120212 may be analyzed.  
Biomarker sample collection may be altered or terminated based on emerging data.  
Tumor marker values will be recorded in the eCRF.5
8.5.9.1.
Optional Circulating Free DNA (cfDNA)
Blood samples may be collected for the analysis of circulating free-DNA (cfDNA).   
Tumor-specific cfDNA has the potential to be a useful biomarker of therapeutic response 
to correlate increasing cfDNA levels with increasing tumor burden.

DATA MANAGEMENT
For this study, data will be collected using defined eCRFs, transmitted electronically to
GSK and combined with data provided from other sources in a validated data system.
Management of clinical data will be performed in accordance with applicable GSK 
standards and data cleaning procedures to ensure the integrity of the data, e.g. removing 
errors and inconsistencies in the data.  AEs and concomitant medications terms will be 
coded using Medical Dictionary for Regulatory Activities (MedDRA) and an internal 
validated medication dictionary, GSK Drug.  Electronic CRFs (including queries and 
audit trails) will be retained by GSK, and copies will be sent to the investigator to 
maintain as the investigator copy.
Laboratory data (i.e., hematology and clinical chemistry) will be stored in a database 
maintained by the central laboratory and transferred to GSK at agreed times.
In all cases, subject initials will not be collected or transmitted to GSK according to GSK 
policy.

As it is anticipated that accrual will be spread thinly across centers and summaries of data 
by center would be unlikely to be informative, data from all participating centers will be 
pooled prior to analysis.  Summaries may be provided grouped by appropriate subject 
populations and/or cohorts.
All data up to the time of study completion/withdrawal from study will be included in the 
analysis, regardless of duration of treatment.
As the duration of treatment for a given subject will depend on efficacy and tolerability, 
the duration of follow-up will vary between subjects.  Consequently there will be no 
imputation for missing data.
Demographic and baseline characteristics will be summarized by cohort and for total 
subjects.  The ATS population will be used for the analysis of safety data.  Complete 
details of the safety analyses will be provided in the RAP.

Safety Analyses
10.3.5.1.
Extent of Exposure
The number of subjects administered study treatment(s) will be listed and summarized by 
cohort according to the duration of therapy.
10.3.5.2.
Adverse Events
Adverse events (AEs) will be coded using MedDRA and grouped by system organ class.  
AEs will be graded by the investigator according to the NCI-CTCAE (version 4.0)
[NCI, 2009].
Events will be summarized by frequency, cohort and proportion of total subjects, by 
system organ class and preferred term. Separate summaries will be given for all AEs, 
drug-related AEs, serious AEs and AEs leading to discontinuation of study treatment(s).
If the AE is listed in the NCI-CTCAE (version 4.0) [NCI, 2009] table, the maximum 
grade will be summarized.
Characteristics (e.g. number of occurrences, action taken, grade, etc) of the following 
AEs of special interest will be summarized separately: rash, visual changes, diarrhea, 
pneumonitis, and LVEF.
The incidence of deaths and the primary cause of death will be summarized by cohort and 
for total subjects.
10.3.5.3.
Clinical Laboratory Evaluations
Hematology and clinical chemistry data will be listed for each subject and summarized at 
each scheduled assessment according to NCI-CTCAE grade (version 4.0)
[NCI, 2009].  The proportion of values lying outside the reference range will also be

presented for laboratory tests that are not graded because there are no associated NCI-
CTCAE criteria.  Summaries will include data from scheduled assessments only, and all 
data will be reported according to the nominal visit date for which it was recorded (i.e., 
no visit windows will be applied).  Unscheduled data will be included in “overall” and 
“any post-screening” summaries which will capture a worst case across all scheduled and 
unscheduled visits post first dose of study treatment(s).  Further details will be provided 
in the RAP.
10.3.5.4.
Other Safety Measures
The results of scheduled assessments of vital signs, 12-lead ECG, and ECHO/MUGA 
scan, will be listed for each subject and summarized by cohort.  All data will be reported 
according to the nominal visit date for which it was recorded (i.e. no visit windows will 
be applied).  Further details will be provided in the RAP.
10.3.5.5.
Clinical Activity Analyses
No efficacy analysis is planned for this study.  To assess clinical activity, the overall 
response based on investigator assessments will be listed and summarized by cohort.  If 
the data warrant, the response data will be summarized by cohort.

CONFIDENTIAL
MEK114375
70
Written informed consent must be obtained from each subject prior to participation in the 
study.  The consent process will be conducted during the Transition Visit.
11.3.
Urgent Safety Measures
If an event occurs that is related to the conduct of the study or the development of the IP, 
and this new event is likely to affect the study of subjects, the Sponsor, and the 
investigator will take appropriate urgent safety measures to protect subjects against any 
immediate hazard.
The Sponsor will work with the investigator to ensure the IEC/IRB is notified.
11.4.
Quality Control (Study Monitoring)
In accordance with applicable regulations, ICH GCP, and GSK procedures, the site will 
be contacted prior to the start of the study to review with the site staff the protocol, study 
requirements, and their responsibilities to satisfy regulatory, ethical, and GSK 
requirements.  When reviewing data collection procedures, the discussion will include 
identification, agreement and documentation of data items for which the eCRF will serve 
as the source document.
The investigator and the head of the medical institution (where applicable) agrees to 
allow the monitor direct access to all relevant documents and to allocate their time and 
the time to their staff to monitor to discuss findings and any issues.
Monitoring visits will be conducted in a manner to ensure that the:

Data are authentic, accurate, and complete.

Safety and rights of subjects are being protected.

Study is conducted in accordance with the currently approved protocol and any other 
study agreements, ICH GCP, and all applicable regulatory requirements.
11.5.
Quality Assurance
To ensure compliance with ICH GCP and all applicable regulatory requirements, GSK 
may conduct quality assurance audits of the site.  Regulatory agencies may conduct a 
regulatory inspection at any time during or after completion of the study.  In the event of 
an audit or inspection, the investigator (and institution) must agree to grant the auditor(s) 
and inspector(s) direct access to all relevant documents and to allocate their time and the 
time of their staff to discuss any findings/relevant issues.
11.6.
Study and Site Closure
The end of the study will be defined as the date of the last visit of the last subject 
enrolled.

RM2010/00127/07
CONFIDENTIAL
MEK114375
71
Upon completion or termination of the study, the monitor will conduct site closure 
activities with the investigator or site staff (as appropriate), in accordance with applicable 
regulations, ICH GCP, and GSK Standard Operating Procedures.
GSK reserves the right to temporarily suspend or terminate the study at any time for 
reasons including (but not limited to) safety issues, ethical issues, or severe 
noncompliance.  If GSK determines that such action is required, GSK will discuss the 
reasons for taking such action with the investigator or head of the medical institution 
(where applicable).  When feasible, GSK will provide advance notice to the investigator 
or head of the medical institution of the impending action.
If a study is suspended or terminated for safety reasons, GSK will promptly inform all 
investigators, heads of the medical institutions (where applicable),and/or institutions 
conducting the study.  GSK will also promptly inform the relevant regulatory authorities 
of the suspension/termination along with the reasons for such action.  Where required by 
applicable regulations, the investigator or head of the medical institution must inform the 
IRB/IEC promptly and provide the reason(s) for the suspension/termination.
11.7.
Records Retention
Following closure of the study, the investigator or head of the medical institution (where 
applicable) must maintain all site study records (except for those required by local 
regulations to be maintained elsewhere) in a safe and secure location.  The records must 
be easily accessible when needed (e.g. for a GSK audit or regulatory inspection) and must 
be available for review in conjunction with assessment of the facility, supporting systems, 
and relevant site staff.
Where permitted by local laws/regulations or institutional policy, some or all of the 
records may be maintained in a format other than hard copy (e.g., microfiche, scanned, 
electronic); however, caution must be exercised before such action is taken.  The 
investigator must ensure that all reproductions are legible and are a true and accurate 
copy of the original.  In addition, they must meet accessibility and retrieval standards, 
including regeneration of a hard copy, if required.  The investigator must also ensure that 
an acceptable back-up of the reproductions exists and that there is an acceptable quality 
control procedure in place for creating the reproductions.
GSK will inform the investigator of the time period for retaining the site records in order 
to comply with all applicable regulatory requirements.  The minimum retention time will 
meet the strictest standard applicable to a particular site, as dictated by local 
laws/regulations, GSK standard operating procedures, and/or institutional requirements.
The investigator must notify GSK of any changes in the archival arrangements, including, 
but not limited to archival of records at an off-site facility or transfer of ownership of the 
records in the event that the investigator is no longer associated with the site.
11.8.
Provision of Study Results to Investigators, Posting to the 
Clinical Trials Register and Publication
Where required by applicable regulatory requirements, an investigator signatory will be 
identified for the approval of the clinical study report.  The investigator will be provided 

RM2010/00127/07
CONFIDENTIAL
MEK114375
72
reasonable access to statistical tables, figures, and relevant reports and will have the 
opportunity to review the complete study results at a GSK site or other mutually-
agreeable location.
GSK will also provide the investigator with the full summary of the study results.  The 
investigator is encouraged to share the summary results with the study subjects, as 
appropriate.
The results summary will be posted to the Clinical Study Register at the time of the first 
regulatory approval or within 12 months of any decision to terminate development. In 
addition, a manuscript will be submitted to a peer-reviewed journal for publication within 
12 months of the first approval or within 12 months of any decision to terminate 
development. When manuscript publication in a peer-reviewed journal is not feasible, 
further study information will be posted to the GSK Clinical Study Register to 
supplement the results summary.

Appendix 3:  NYHA Functional Classification System
The New York Heart Association (NYHA) Functional Classification: Class I, II, III 
or IV Heart Failure [NYHA, 1994] provides a simple way of classifying the extent of 
heart failure.  It places subjects in one of 4 categories based on the level of limitation 
experienced during physical activity:
Class
Symptoms
Class I
(Mild)
No limitation of physical activity.  Ordinary physical activity does not cause 
undue fatigue, palpitation or dyspnea (shortness of breath).
Class II
(Mild)
Slight limitation of physical activity.  Comfortable at rest, but ordinary 
physical activity results in fatigue, palpitation or dyspnea.
Class III
(Moderate)
Marked limitation of physical activity.  Comfortable at rest, but less than 
ordinary physical activity results in fatigue, palpitation or dyspnea.
Class IV
(Severe)
Unable to carry out any physical activity without discomfort.  Symptoms of 
cardiac insufficiency at rest.  If any physical activity is undertaken, discomfort 
is increased.

Appendix 6:  Protocol Changes
AMENDMENT 7
Where the Amendment Applies
Amendment 07 applies to all sites that are or will be conducting this study. 
Summary of Amendment Changes with Rationale
In this amendment, standard language changes based on CIB V 05 report date 25 Sept 
2013 were made to Stopping Criteria for Visual Changes and Ophthalmologic 
Examinations.  Exclusion Criteria number 2 was deleted as local commercial availability 
of the study drug is no longer considered to be a major exclusion criterion.  Table 1
GSK1120212 Investigation Product (description) was deleted as only the commercial 
drug is now being used in studies.  Tables and table references throughout the protocol 
were renumbered accordingly.  The Handling and Storage of Study Treatment was 
revised to refer investigators to the drug label and SPM for detailed handling and storage 
directions.  CIB V 05 report date 25 Sep 2013 was added to the CIB reference.  Authors, 
Sponsor Signatory and Sponsor/Medical Monitor Information pages were revised to
reflect changes in GSK study team members.  Administrative changes were made for 
typographical (punctuation) omissions and errors.

Section 5.7.5. Stopping Criteria for Visual Changes, paragraph 1
PREVIOUS TEXT:
For all visual changes, regardless of grade, a blood sample for PK analysis must be drawn 
as close as possible to the time of the event.  Visual change events should be graded using 
Table 8 based on the NCI-CTCAE, version 4.0 [NCI 2009]).
REVISED TEXT:
Episodes of visual changes have been observed in subjects receiving trametinib, and 
ocular adverse events are known to be related to trametinib. An ophthalmologist 
should be consulted if changes in vision develop.  If the visual changes are clearly 
unrelated to study treatment (e.g., allergic conjunctivitis), then monitor closely as it 
may be reasonable to defer ophthalmic examination. Special attention should be 
given to retinal findings (e.g., retinal pigment epithelial detachment (RPED) or 
retinovascular abnormalities (i.e., branch or central retinal vein occlusions (RVO).  
For events of visual changes (regardless of severity) for which an ophthalmic 
examination is conducted, a blood sample for PK analysis must be drawn as close as 
possible to the time of the event.
Visual change events should be graded using Table 7 based on the NCI-CTCAE, version 
4.0 [NCI 2009]).

and Grade 4 Visual Changes
PREVIOUS TEXT:
Grade 1 visual changes:

For Grade 1 visual changes that do not affect vision and which, in the option 
of the treating physician, are clearly unrelated to study treatment (e.g., 
conjunctivitis), treatment with GSK1120212 may continue with close 
observation.

If attribution to study treatment is unclear, immediately refer the subject for 
ophthalmic exam; if an ophthalmic exam cannot be performed within 7 
days, interrupt treatment with GSK1120212 until exam can be 
performed and follow the guidance below depending on the results.
If a retinal abnormality is noted, interrupt treatment with GSK1120212 
immediately and referral to a retinal specialist should be considered for 
further evaluation.

If RVO is diagnosed, report as a SAE and permanently discontinue 
treatment with GSK1120212

If CSR is diagnosed, interrupt treatment with GSK1120212 until signs and 
symptoms have resolved.  Resume treatment with GSK1120212 at a dose 
reduced by 1 dose level.

If there is no evidence of RVO or CSR, resume treatment with GSK1120212 
at the same dose level.  
Grade 2 or Grade 3 visual changes:

Immediately interrupt treatment with GSK1120212 and refer subject to an 
ophthalmologist for evaluation with an ophthalmic exam.  For all subjects 
with findings consistent with RVO or CSR based on the ophthalmic exam, 
referral to retinal specialist, if available, should be considered for further 
evaluation.

If RVO is diagnosed, report as a SAE and permanently discontinue 
GSK1120212

If CSR is diagnosed, interrupt treatment with GSK1120212 until signs 
and symptoms have resolved and then resume treatment with 
GSK1120212 at reduced dose by at least one dose level.

If there is no evidence of RVO or CSR, interrupt treatment with 
GSK1120212 until signs and symptoms have returned to Grade 1 or 
resolved.  Resuming treatment with GSK1120212 at the same dose level 
may be considered if visual changes are clearly unrelated to study 
treatment.

Section 8.4.2. Ophthalmologic Examinations
PREVIOUS TEXT:
All subjects transitioning to the rollover study are expected to have had a standard 
ophthalmic exam performed by an ophthalmologist during Screening in their parent 
study.  Ophthalmologic examinations will be conducted during the rollover study if 
clinically indicated (refer to Section 5.7.5 for stopping criteria for visual changes).  If an 
ophthalmologic examination is necessary, it should include indirect fundoscopic 
examination, visual acuity, visual field examination, tonometry, and direct fundoscopy, 
with special attention to retinal abnormality that are predisposing factors for RVO or 
CSR.
For subjects with clinical suspicion of RVO or CSR, additional color fundus photos are 
recommended if they can be acquired, and fluorescein angiography and/or optical 
coherence tomography are highly recommended.

AMENDMENT 6
Where the Amendment Applies
Amendment 06 applies to all sites that are or will be conducting this study. 
Summary of Amendment Changes with Rationale
In this amendment, standard language changes based on CIB V 04 report date 05 Sep 
2012 were made to QTc Withdrawal Criteria, LVEF Stopping Criteria, Management of 
Hypertension, Inclusion Criteria, Pregnancy and Contraception.  The requirements for 
male contraception were deleted from the Inclusion Criteria and sections on Pregnancy 
and Contraception as the use of contraception with female partners of childbearing 
potential is not recommended based on the absence of genotoxicity, no effects on male 
reproductive tissues in nonclinical toxicity studies, and the minimal potential for 
trametinib exposure of females via semen. The decreased frequency of interim visits for 
those subjects who have been on study >52 weeks was more clearly define to be for those 
subjects who have in addition to being on study >52 weeks have also tolerated therapy 
well with limited toxicities and to be with the approval and direction of the GSK medical 
monitor. The 1mg tablet was deleted from Table 1 GSK1120212 Investigational Product 
as the 1mg tablet is no longer available.  Typographical errors were corrected.
Section 3.1. Cohorts
PREVIOUS TEXT:
Cohort A:
Cohort A will consist of subjects who have completed <24 weeks of treatment with 
GSK1120212 monotherapy during their participation in the parent study.  It is anticipated 
that subjects in this cohort will have participated in a clinical pharmacology or another 
short-term study of GSK1120212.  Subjects will complete the Transition Visit and return 
for their next scheduled visit (Study Week 4), and then every 4 weeks thereafter.  
Subjects who remain on study treatment >52 weeks may have the frequency of their 
interim visits decreased with approval from the GSK Medical Monitor.
Subjects will receive GSK1120212 as an oral, daily dose of 2 mg or less.  Protocol 
specified guidelines for dose modifications and treatment discontinuation criteria are 
provided in Section 5.6 and Section 5.7, respectively.  If there are any uncertainties about 
the dose to be administered in this study, the GSK Medical Monitor should be consulted.  
Once treatment with GSK1120212 is discontinued the subject is to be withdrawn from 
the rollover study.
Cohort B:
Cohort B will consist of subjects who have completed 24 weeks of treatment with 
GSK1120212 (either as monotherapy or combination therapy with an approved anti-
cancer agent) during their participation in the parent study.  Subjects who transition from

a combination study may continue to receive GSK1120212 in combination with the 
approved anti-cancer agent defined by the parent study or if, in the opinion of the 
investigator, the subject has received maximum benefit or is experiencing unacceptable 
toxicity from the approved anti-cancer agent, then treatment with the approved anti-
cancer agent may be discontinued and the subject may remain on study for continued 
treatment with GSK1120212 alone.  Once treatment with GSK1120212 is discontinued 
the subject is to be withdrawn from the rollover study.
Subjects will complete the Transition Visit assessments and then return for their next 
scheduled visit (Study Week 3 or 4), then every 3 or 4 weeks thereafter (depending on the 
schedule used in the parent study).  Subjects who remain on study treatment >52 weeks 
may have the frequency of their interim visits decreased with approval from the GSK 
Medical Monitor.  
All subjects will receive GSK1120212 at the current dose level administered in the parent 
study at the time of the Transition Visit.  If this starting dose of GSK1120212 is below 
the recommended Phase 2 dose (RP2D) previously defined for the given treatment 
regimen (e.g., dose modification following recovery from toxicity), the investigator, after 
consultation with the GSK Medical Monitor, may consider escalating the dose to the 
RP2D.  If there are any uncertainties about the dose(s) to be administered in this study, 
the GSK Medical Monitor should be consulted.
REVISED TEXT
Cohort A:
Cohort A will consist of subjects who have completed <24 weeks of treatment with 
GSK1120212 monotherapy during their participation in the parent study.  It is anticipated 
that subjects in this cohort will have participated in a clinical pharmacology or another 
short-term study of GSK1120212.  Subjects will complete the Transition Visit and return 
for their next scheduled visit (Study Week 4), and then every 4 weeks thereafter.  
Subjects who have tolerated therapy well with limited toxicities and remain on study 
treatment >52 weeks may have the frequency of their interim visits decreased with 
approval and direction from the GSK Medical Monitor.
Subjects will receive GSK1120212 as an oral, daily dose of 2 mg or less.  Protocol 
specified guidelines for dose modifications and treatment discontinuation criteria are 
provided in Section 5.6 and Section 5.7, respectively.  If there are any uncertainties about 
the dose to be administered in this study, the GSK Medical Monitor should be consulted.  
Once treatment with GSK1120212 is discontinued the subject is to be withdrawn from 
the rollover study.
Cohort B:
Cohort B will consist of subjects who have completed 24 weeks of treatment with 
GSK1120212 (either as monotherapy or combination therapy with an approved anti-
cancer agent) during their participation in the parent study.  Subjects who transition from 
a combination study may continue to receive GSK1120212 in combination with the 
approved anti-cancer agent defined by the parent study or if, in the opinion of the 
investigator, the subject has received maximum benefit or is experiencing unacceptable

Section 5.7.7 QTc Withdrawal Criteria
PREVIOUS TEXT:
QTc should be assessed at the frequency shown in Appendix 1: Time and Events Table 
for Cohort A or Appendix 2: Time and Events Table for Cohort B.
A subject that experiences a Grade 3 (QTcB ≥501 msec on at least two separate 
ECGs) or Grade 4 (QTcB≥501 or >60 msec change from baseline and Torsade de 
pointes or polymorphic ventricular tachycardia or signs/symptoms of serious 
arrhythmia) prolongation of the corrected QT1 interval will have study treatment 
with GSK1120212 withheld:
1 based on average QTc value of triplicate ECGs (confirmed via manual over-read).  For example, if an 
ECG demonstrates a prolonged QT interval, obtain 2 more ECGs over a brief period, and then use the 
averaged QTc values of the 3 ECGs to determine whether the subjects should have study treatment 
withheld.
If the QTc prolongation resolves to grade 1 (450 - 480 msec) or baseline, the subject 
may be re-started on the study treatment at current dose level if the investigator and 
GSK Medical Monitor agree that the subject will benefit from further treatment.
REVISED TEXT:
QTc should be assessed at the frequency shown in Appendix 1: Time and Events Table 
for Cohort A or Appendix 2: Time and Events Table for Cohort B.
A subject who experiences a QTc prolongation1 defined as QTcB ≥501 msec or 
uncorrected QT>600 msec or QTcB>530  msec for subjects with bundle branch 
block will have study treatment with GSK1120212 withheld:
1 based on average QTc value of triplicate ECGs (confirmed via manual over-read).  For example, if an 
ECG demonstrates a prolonged QT interval, obtain 2 more ECGs over a brief period, and then use the 
averaged QTc values of the 3 ECGs to determine whether the subjects should have study treatment

If the QTc prolongation resolves to grade 1 (450 - 480 msec) or baseline, the subject 
may be re-started on the study treatment at current dose level if the investigator and 
GSK Medical Monitor agree that the subject will benefit from further treatment.  If the 
event does not resolve or recurs, permanently discontinue study treatment.

Section 5.7.8.1 Left Ventricular Ejection Fraction Stopping Criteria, Second 
Paragraph, Bullet #2 and Third Paragraph
PREVIOUS TEXT:
Subject who have an asymptomatic, absolute decrease of >10% in LVEF compared with 
baseline (baseline value from parent study) and the ejection fraction is below the 
institution’s LLN should have treatment with GSK1120212 withheld and a repeat 
evaluation of LVEF within 2 weeks.  

If the LVEF recovers (defined as LLN and absolute decrease 10% compared 
with baseline [baseline value from parent study]) at any time during the next 
4 weeks, after consultation and approval of the GSK Medical Monitor, the 
subject may be restarted on GSK1120212 at a reduced dose.  For such subjects, 
monitoring of LVEF will be performed 2 and 4 weeks after rechallenge, and 
every 4 weeks thereafter for 12 weeks, and then per protocol.

If repeat LVEF does not recover within 4 weeks, treatment with GSK1120212 
should be permanently discontinued.  Ejection fraction should be monitored in 
2 weeks and then every 4 weeks for a total of 16 weeks or until resolution.
Subjects with Grade 3 or 4 (symptomatic) left ventricular systolic dysfunction must 
discontinue treatment with GSK1120212. Ejection fraction should be monitored at 
2 weeks, at 4 weeks, and then every 4 weeks for a total of 16 weeks or until resolution.  
Evaluation by a cardiologist should be considered.

within 2 weeks of learning of its occurrence. The pregnancy must be followed to 
determine outcome (including premature termination) and status of mother and child.
Pregnancy complications and elective terminations for medical reasons must be reported 
as an AE or SAE. Spontaneous abortions must be reported as a SAE.
Any SAE occurring in association with a pregnancy brought to the investigator’s 
attention after the subject has completed the study and considered by the investigator as 
possibly related to the study treatment, must be promptly reported to GSK.
In addition, the investigator must attempt to collect pregnancy information on any female 
partners of male study subjects who become pregnant while the subject is enrolled in the 
study. Pregnancy information must be reported to GSK as described above.

1.
All subjects transitioning from parent study will begin the rollover study based on the last treatment visit 
completed during the parent study.  All Transition Visit assessments/procedures must be completed prior to 
the first dose of study treatment(s).  Assessments/procedures may be used to fulfill the requirements of both 
the parent study and this study.  Results from the parent study should be recorded in the eCRF as transition 
values.
2.
Informed consent must be obtained prior to performing any assessments or procedures for this study and 
before treatment with GSK1120212 is to be continued.
3.
Physical examination will be completed at the Transition Visit, Week 8 and every 12 weeks thereafter while 
on treatment, and at the Final Study Visit. Height (cm) and weight (kg) will be measured only at the Transition 
Visit.
4.
Serum β–hCG pregnancy tests will be performed on female subjects of childbearing potential only at the time 
of transition from the parent study.
5.
Vital signs (BP, temperature, respiratory rate, and pulse rate) should be taken in a semi-supine position and 
after the subject has rested for at least 5 minutes prior to the reading.  Vital signs may be measured more 
frequently as clinically indicated.
6.
A single 12-Lead ECG will be performed using a standard 12-lead ECG machine.  All ECGs will be taken in a 
supine position after resting in that position for at least 10 minutes prior to testing.  QTc interval must not be 
>500 msec.
7.
12-lead ECGs will be performed every 12 weeks (at a minimum or more frequently per local practice) for the 
first 2 years of treatment (including time on parent study).  After 2 years of treatment 12-lead ECGs will be 
performed every 24 weeks for the duration of treatment.
8.
ECHO or MUGA scan should be performed every 12 weeks (at a minimum or more frequently per local 
practice).  If LVEF decreases 20 percentage points, repeat testing is required within 2 weeks.  If decline is 
sustained, the investigator, in consultation with GSK Medical Monitor, should consider withdrawal of subject 
from the study.
9.
ECHO is only required at the Final Study Visit if an abnormal finding is reported from the last ECHO or 
MUGA scan performed
10. Refer to Section 8.4.5 for complete list of clinical laboratory assessments to be performed.
11. Hematology and clinical chemistry laboratory assessments will be performed every 4 weeks (at a minimum 
or more frequently per local practice) for the first 2 years of treatment (including time on parent study).  After 
2 years hematology and clinical chemistry laboratory assessments will be performed every 12 weeks for the 
duration of treatment.
12. Liver function tests (AST, ALT, alkaline phosphatase and total bilirubin) will be performed every 4 
weeks (depending on the scheduled used in the parent study; at a minimum or more frequently per 
local practice) for the first 2 years of treatment (including time on parent study).  After 2 years liver 
function tests will be performed every 12 weeks (depending on schedule used in the parent study) for 
the duration of treatment.  Bilirubin fractionation is recommended if total bilirubin is >2 times ULN.
13. Optional tumor tissue, skin or blood sample from a lesion not required for disease assessment and/or 
optional blood sample for cfDNA may be obtained if subject has provided consent.
14. AEs/SAEs will be monitored and recorded beginning on the time of consent until 30 days after the last dose 
of GSK2118436.
15. All ongoing (unresolved) AEs at the time of the transition to this study will be recorded in the eCRF.
16. All concomitant medication(s) at the time of the transition to this study will be recorded in the eCRF.
17. The “Every 8 Weeks”, “Every 12 Weeks” or “Every 24 Weeks” columns are NOT a separate visit but instead 
a listing of assessments required to be completed every 8, 12 or 24 weeks or every second or third clinic visit 
that is recurring at 4-week intervals, respectively.
18. After a subject has been on study for a total of 2 years, including time on parent study, the frequency of 
assessments will be modified.  If more frequent assessments are needed, these should be done per local 
practice.
19. The Final Study Visit should occur within 28 days (7 days) following the last dose of study treatment(s) and 
prior to initiating any new treatment.
20. Subjects who remain on study treatment >52 weeks may have the frequency of their interim visits decreased 
with approval from the GSK Medical Monitor.

1.
All subjects transitioning from parent study will begin the rollover study based on the last treatment visit 
completed during the parent study.  All Transition Visit assessments/procedures must be completed prior to 
the first dose of study treatment(s).  Assessments/procedures may be used to fulfill the requirements of both 
the parent study and this study.  Results from the parent study should be recorded in the eCRF as transition 
values.
2.
Informed consent must be obtained prior to performing any assessments or procedures for this study and 
before treatment with GSK1120212 is to be continued.
3.
Physical examination will be completed at the Transition Visit, Week 8 and every 12 weeks thereafter while 
on treatment, and at the Final Study Visit. Height (cm) and weight (kg) will be measured only at the Transition 
Visit.
4.
Serum β–hCG pregnancy tests will be performed on female subjects of childbearing potential only at the time 
of transition from the parent study.
5.
Vital signs (BP, temperature, respiratory rate, and pulse rate) should be taken in a semi-supine position and 
after the subject has rested for at least 5 minutes prior to the reading.  Vital signs may be measured more 
frequently as clinically indicated.
6.
A single 12-Lead ECG will be performed using a standard 12-lead ECG machine.  All ECGs will be taken in a 
supine position after resting in that position for at least 10 minutes prior to testing.  QTc interval must not be 
>500 msec.
7.
12-lead ECGs will be performed every 12 weeks (at a minimum or more frequently per local practice) for the 
first 2 years of treatment (including time on parent study).  After 2 years of treatment 12-lead ECGs will be 
performed every 24 weeks for the duration of treatment.
8.
ECHO or MUGA scan should be performed every 12 weeks (at a minimum or more frequently per local 
practice).  If LVEF decreases 20 percentage points, repeat testing is required within 2 weeks.  If decline is 
sustained, the investigator, in consultation with GSK Medical Monitor, should consider withdrawal of subject 
from the study.
9.
ECHO is only required at the Final Study Visit if an abnormal finding is reported from the last ECHO or 
MUGA scan performed
10. Refer to Section 8.4.5 for complete list of clinical laboratory assessments to be performed.
11. Hematology and clinical chemistry laboratory assessments will be performed every 4 weeks (at a minimum 
or more frequently per local practice) for the first 2 years of treatment (including time on parent study).  After 
2 years hematology and clinical chemistry laboratory assessments will be performed every 12 weeks for the 
duration of treatment.
12. Liver function tests (AST, ALT, alkaline phosphatase and total bilirubin) will be performed every 4 
weeks (depending on the scheduled used in the parent study; at a minimum or more frequently per 
local practice) for the first 2 years of treatment (including time on parent study).  After 2 years liver 
function tests will be performed every 12 weeks (depending on schedule used in the parent study) for 
the duration of treatment.  Bilirubin fractionation is recommended if total bilirubin is >2 times ULN.
13. Optional tumor tissue, skin or blood sample from a lesion not required for disease assessment and/or 
optional blood sample for cfDNA may be obtained if subject has provided consent.
14. AEs/SAEs will be monitored and recorded beginning on the time of consent until 30 days after the last dose 
of GSK1120212.
15. All ongoing (unresolved) AEs at the time of the transition to this study will be recorded in the eCRF.
16. All concomitant medication(s) at the time of the transition to this study will be recorded in the eCRF.
17. The “‘Week 8”, “Every 12 Weeks” or “Every 24 Weeks” columns are NOT a separate visit but instead a listing 
of assessments required to be completed at week 8, and every 12 or 24 weeks or every second or third 
clinic visit that is recurring at 4-week intervals, respectively.
18. After a subject has been on study for a total of 2 years, including time on parent study, the frequency of 
assessments will be modified.  If more frequent assessments are needed, these should be done per local 
practice.
19. The Final Study Visit should occur within 28 days (7 days) following the last dose of study treatment(s) and 
prior to initiating any new treatment.
20. Subjects who have tolerated therapy well with limited toxicities and remain on study treatment >52 
weeks may have the frequency of their interim visits decreased with approval and direction from the GSK 
Medical Monitor.

AMENDMENT 5
Where the Amendment Applies
Amendment 05 applies to all sites that are or will be conducting this study. 
Summary of Amendment Changes with Rationale
In this amendment, actions regarding study treatment, GSK1120212 (Trametinib), should 
the subject experience a Grade 3 or Grade 4 prolongation of the QTc interval was 
provided in greater detail at the request of the FDA.  The time span for females to use 
contraception was revised; prohibited medications and non-drug therapies were revised to 
reflect recent changes in the standard language. Additionally, the Exclusion Criteria were 
revised to be more in line with those of the subject’s parent study and less restrictive for 
eligible subjects who are transitioning to the MEK114375 study.  Trametinib, the 
commercial name of GSK1120212, was added to the subject line on the title page.

Section 5.7.7 QTc Withdrawal Criteria
PREVIOUS TEXT:
QTc should be assessed at the frequency shown in Appendix 1: Time and Events Table 
for Cohort A or Appendix 2: Time and Events Table for Cohort B.
A subject that meets the QTc1 criteria below will have study treatment with GSK1120212 
withheld:

QTcB >530 msec, or uncorrected QT >600 msec
1 based on average QTc value of triplicate ECGs (confirmed via manual over-read).  For example, if an 
ECG demonstrates a prolonged QT interval, obtain 2 more ECGs over a brief period, and then use the 
averaged QTc values of the 3 ECGs to determine whether the subjects should have study treatment 
withheld.

112
If the QTc prolongation resolves to <500 msec, the subject may be re-started on the study 
treatment if the investigator and GSK Medical Monitor agree that the subject will benefit 
from further treatment.
REVISED TEXT:
QTc should be assessed at the frequency shown in Appendix 1: Time and Events Table 
for Cohort A or Appendix 2: Time and Events Table for Cohort B.
A subject that experiences a Grade 3 (QTcB ≥501 msec on at least two separate 
ECGs) or Grade 4 (QTcB ≥501 or >60 msec change from baseline and Torsade de 
pointes or polymorphic ventricular tachycardia or signs/symptoms of serious 
arrhythmia) prolongation of the corrected QT1 interval will have study treatment 
with GSK1120212 withheld:
1 based on average QTc value of triplicate ECGs (confirmed via manual over-read).  For example, if an 
ECG demonstrates a prolonged QT interval, obtain 2 more ECGs over a brief period, and then use the 
averaged QTc values of the 3 ECGs to determine whether the subjects should have study treatment 
withheld.
If the QTc prolongation resolves to grade 1 (450 – 480 msec) or baseline, the subject 
may be re-started on the study treatment at current dose level, if the investigator and 
GSK Medical Monitor agree that the subject will benefit from further treatment.

All subjects transitioning from parent study will begin the rollover study based on the last treatment visit 
completed during the parent study.  All Transition Visit assessments/procedures must be completed prior to 
the first dose of study treatment(s).  Assessments/procedures may be used to fulfill the requirements of both 
the parent study and this study.  Results from the parent study should be recorded in the eCRF as transition 
values.
2.
Informed consent must be obtained prior to performing any assessments or procedures for this study and 
before treatment with GSK1120212 is to be continued.
3.
Physical examination will be completed at the Transition Visit, Week 8 and every 12 weeks thereafter while 
on treatment, and at the Final Study Visit. Height (cm) and weight (kg) will be measured only at the Transition 
Visit.
4.
Serum β–hCG pregnancy tests will be performed on female subjects of childbearing potential only at the time 
of transition from the parent study.
5.
Vital signs (BP, temperature, respiratory rate, and pulse rate) should be taken in a semi-supine position and 
after the subject has rested for at least 5 minutes prior to the reading.  Vital signs may be measured more 
frequently as clinically indicated.
6.
A single 12-Lead ECG will be performed using a standard 12-lead ECG machine.  All ECGs will be taken in a 
supine position after resting in that position for at least 10 minutes prior to testing.  QTc interval must not be 
>480 msec.
7.
12-lead ECGs will be performed every 12 weeks (at a minimum or more frequently per local practice) for the 
first 2 years of treatment (including time on parent study).  After 2 years of treatment 12-lead ECGs will be 
performed every 24 weeks for the duration of treatment.
8.
ECHO or MUGA scan should first be performed at Week 8 and then every 12 weeks (at a minimum or more 
frequently per local practice).  If LVEF decreases 20 percentage points, repeat testing is required within 
2 weeks.  If decline is sustained, the investigator, in consultation with GSK Medical Monitor, should consider 
withdrawal of subject from the study.
9.
ECHO is only required at the Final Study Visit if an abnormal finding is reported from the last ECHO or 
MUGA scan performed
10. Refer to Section 8.4.5 for complete list of clinical laboratory assessments to be performed.
11. Hematology and clinical chemistry laboratory assessments will be performed every 4 weeks (at a minimum 
or more frequently per local practice) for the first 2 years of treatment (including time on parent study).  After 
2 years hematology and clinical chemistry laboratory assessments will be performed every 12 weeks for the 
duration of treatment.
12. Liver function tests (AST, ALT, alkaline phosphatase and total bilirubin) will be performed every 4 
weeks (depending on the scheduled used in the parent study; at a minimum or more frequently per 
local practice) for the first 2 years of treatment (including time on parent study).  After 2 years liver 
function tests will be performed every 12 weeks (depending on schedule used in the parent study) for 
the duration of treatment.  Bilirubin fractionation is recommended if total bilirubin is >2 times ULN.
13. Optional tumor tissue, skin or blood sample from a lesion not required for disease assessment and/or 
optional blood sample for cfDNA may be obtained if subject has provided consent.
14. AEs/SAEs will be monitored and recorded beginning on the time of consent until 30 days after the last dose 
of GSK2118436.
15. All ongoing (unresolved) AEs at the time of the transition to this study will be recorded in the eCRF.
16. All concomitant medication(s) at the time of the transition to this study will be recorded in the eCRF.
17. The “Every 8 Weeks”, “Every 12 Weeks” or “Every 24 Weeks” columns are NOT a separate visit but instead 
a listing of assessments required to be completed every 8, 12 or 24 weeks or every second or third clinic visit 
that is recurring at 4-week intervals, respectively.
18. After a subject has been on study for a total of 2 years, including time on parent study, the frequency of

AMENDMENT 3
Where the Amendment Applies
This amendment applies to all site and countries.
Summary of Amendment Changes with Rationale
In this amendment, new hypertension guidelines were added based on recent reports of 
hypertensive events in subjects receiving GSK1120212.  In addition, the exclusion 
criteria based on cardiovascular risk was expanded to include additional criteria based 
upon recent cardiac events reported in an ongoing MEK study.  The protocol section 
providing background information on GSK1120212 was also revised to remove text that 
does not correctly summarize the mechanism of action noted preclinically; additional text 
was inserted to provide a more accurate description of the specificity of GSK1120212.  
Other changes were made to correct inconsistencies between sections regarding 
administration of GSK1120212 and the need to perform an ECHO or MUGA at the final 
study visit outlined in the study assessments section and the Time and Events Tables.

Section 5.7.1
Monitoring and Management of Hypertension
Section 5.7.1.1
Monitoring of Hypertension
All BP assessments should be performed under optimal conditions i.e. after (1) 
subject has been seated with back support, ensuring that legs are uncrossed and flat 
on the floor, (2) subject is relaxed comfortably for at least 5 minutes, (3) 
preparatory steps including removal of any restrictive clothing over the cuff area 
and selection of the proper cuff size have been ensured, (4) the arm is supported so 
that the middle of the cuff is at the heart level, and (5) the subject remains quiet 
during the measurement.  In subjects with an initial BP reading within the 
hypertensive range, a second reading should be taken at least 1 minute later, with 
the 2 readings averaged to obtain a final BP measurement. 
Persistent hypertension is defined as an increase of systolic blood pressure (SBP) 
>140 mm Hg and/or diastolic blood pressure (DBP) >90 mmHg in up to 3 
subsequent visits with BP assessments from 2 readings under the optimal conditions 
described above.  Visits to monitor increased BP should be scheduled independently 
from the per-protocol visits outlined in the time-and-events schedule; ideally, 
subsequent BP assessments should be performed within 7 days.
Asymptomatic hypertension is defined as an increase of SBP >140 mmHg and/or 
DBP > 90 mmHg in the absence of headache, light-headedness, vertigo, tinnitus, 
episodes of fainting or other symptoms indicative of hypertension which would 
disappear after the BP is controlled within the normal range. 
Section 5.7.1.2
Management of Hypertension
For subjects experiencing an increase in SBP and/or DBP that is persistent and may 
be associated with the study treatment, recommendations for the clinical 
management of hypertension are described below:

AMENDMENT 2
Where the Amendment Applies
This amendment applies to all site and countries.
Summary of Amendment Changes with Rationale
In this amendment, the background information and risk management sections of the 
protocol were revised to provide updated safety information included in the most recent 
version of the GSK1120212 IB.  In addition, since the new commercial image 
investigational product will be administered to subjects participating in this protocol, it 
was necessary to add the product description.
The language describing the timing of the ECHOs and MUGA scans was revised to 
further clarify that ECHO/MUGA should be completed 12 weeks from the subject’s last 
scan not necessarily 12 weeks from the date of the transition visit.
Administrative changes were made to update contact information for the primary and 
secondary medical monitors.

with a variety of cancers.  The investigator should refer to the GSK1120212 IB 
[GlaxoSmithKline Document Number HM2009/00151/] for detailed information 
regarding ongoing GSK1120212 clinical studies, PK in the target disease population, as 
well as observed safety and efficacy findings. 
The adverse event (AE) profile of GSK1120212 observed to date is comparable to other 
MEK inhibitors [Friday, 2008].  For example, rash and diarrhea, experienced by 70% and 
41% of subjects, respectively, are the most common toxicities reported in the first-time-
in-human study, MEK111054 [GlaxoSmithKline Document Number RM2007/00642/03].  
Rash was considered a dose-limiting toxicity (DLT) in 2 subjects (Grade 2 and Grade 3), 
whereas a DLT for Grade 3 diarrhea occurred once.   Other AEs commonly reported 
(≥20%) include fatigue, nausea, peripheral edema, and vomiting.  Although observed at 
lower frequencies, visual impairment and left ventricular ejection fraction (LVEF) 
reduction have been observed with GSK1120212 as well as other MEK inhibitors.  
Visual impairment includes 2 cases of dose-limiting Grade 2 central serous retinopathy 
(CSR) and 1 case of Grade 3 retinal vein occlusion (RVO).  Pneumonitis has also been 
seen in subjects treated with GSK1120212 in combination with gemcitabine.
GSK1120212 has demonstrated anti-tumor activity in a variety of solid tumors as well as 
in 1 subject with acute myelogenous leukemia.  Importantly, 1 out of 2 subjects with 
KRAS-mutant metastatic non-small cell lung cancer (NSCLC) has achieved a partial 
response (PR; 49% tumor reduction) and one out of 18 advanced pancreatic subjects has 
a sustained PR (on study >40 weeks) following treatment with GSK1120212 
monotherapy.  
Although tumor response appears to higher in those subjects whose cancer harbors 
mutations in the MAPK signalling pathway, clinical benefit is still observed in subjects 
with wild-type disease or disease where the mutation status is unknown.  For example, 
multiple NSCLC and pancreatic cancer subjects have achieved stable disease (SD).

reduction have been observed with GSK1120212 as well as other MEK inhibitors.  
Visual impairment includes 2 cases of dose-limiting Grade 2 central serous retinopathy 
(CSR) and 1 case of Grade 3 retinal vein occlusion (RVO).  Pneumonitis has also been

Although tumor response appears to higher in those subjects whose cancer harbors 
mutations in the MAPK signalling pathway, clinical benefit is still observed in subjects 
with wild-type disease or disease where the mutation status is unknown.  For example, 
multiple NSCLC and pancreatic cancer subjects have achieved stable disease (SD).
As of 14 April 2011, 657 subjects with cancer have received at least one dose of 
GSK1120212 in 14 ongoing Phase I/II/III clinical studies.  Six of the 14 studies 
administer GSK1120212 as monotherapy, whereas the other 8 studies are designed 
to administer GSK112012 as combination therapy.  As of 14 April 2011, 206 
subjects in MEK111054, the first-time-in-human (FTIH) study of GSK1120212, had 
been dosed with GSK1120212.  Dose-related MAP kinase inhibition was 
demonstrated between daily doses of 0.5 and 2.0 mg with immunohistochemistry on 
tumor biopsies.  Modulation of MAP kinase pathways was consistent with changes 
observed with fluorodeoxyglucose-positron emission tomography imaging.  Based 
on the AEs observed in the FTIH MEK111054 study, the maximum tolerated dose 
(MTD) was determined to be 3.0 mg once-daily and the recommended Phase II dose 
(RP2D) of GSK1120212 was identified as 2.0 mg once-daily.  An unconfirmed 
response rate of 43% (6 out of 14 subjects) had an objective response, including 2 
complete responses (CRs) was observed.    The recommended monotherapy dose (2 
mg once-daily) was well-tolerated.  Most notable adverse events (AEs) at this dose 
(n = 96) included class effects of rash (78%; 4% Grade 3) and diarrhea (54%; 1% 
Grade 3).  In all subjects dosed (n = 206), 5 cases of Grade 3 left ventricular systolic 
dysfunction, 3 cases of central serous retinopathy (CSR), and 1 case of retinal vein 
occlusion (RVO) were observed.  Among the 5 left ventricular ejection fraction 
(LVEF) cases, only 2 were considered related to study treatment and neither subject 
was symptomatic.  All 3 cases of CSR resolved upon study treatment interruption, 
and the subject with RVO has experienced significant improvement in visual acuity 
after intraocular bevacizumab treatments.

GSK1120212 is absorbed rapidly with median tmax generally occurring within 1 to 
3 hours after administration of GSK1120212.  After repeat dosing (Study Day 15), 
the mean area under the concentration-time curve (AUC0-)) and maximum 
observed concentrations (Cmax) increased in a dose proportional manner (i.e., a 2-
fold increase in dose resulted in a 2-fold increase in exposure).  Between-subject 
variability (CV%) in exposure ranged from 27 to 50% for Cmax and 20 to 41% for 
area under the concentration-time curve from time zero (pre-dose) to 24 hrs after 
the last dose of study treatment (AUC(0-24)) across all dosing regimens.  
GSK1120212 accumulates with repeat dose with an effective half-life (t1/2) of 
approximately 5 days.
Further information on the safety, PK, and efficacy is described in the IB for 
GSK1120212 [GlaxoSmithKline Document Number HM2009/00151/02].
Section 1.2 Summary of Risk Management
Added new Section 1.2 and renumbered old Section 1.2 to Section 1.3.
NEW TEXT
The assessment of the risk of GSK1120212 is based on clinical data from the 
ongoing FTIH study in which subjects have been dosed daily for >21 days, as well as 
preclinical toxicity data.  In study MEK111054, the most common AEs experienced 
by 20% of all subjects with daily dosing were rash, diarrhea, fatigue, nausea, 
peripheral edema, and vomiting.  Rash and diarrhea are common, class-effect 
toxicities for MEK inhibitors.  In addition, visual impairment and LVEF reduction, 
although observed at lower frequencies, are also considered class-effect toxicities as 
they have been observed with GSK1120212 as well as other MEK inhibitors.  
Systemic toxicity of GSK1120212 has been evaluated following oral dosing in rats 
and dogs for up to 13 weeks.  In the most sensitive non-clinical species, rat, the 
principal adverse effects seen in oral toxicity studies of up to 13 weeks with daily 
dosing were skin and stomach erosions, skin ulcerations, which were secondary to 
reduced proliferation, altered phosphate homeostasis that resulted in soft tissue 
mineralization, hepatocellular necrosis, bone marrow degeneration/necrosis and 
ovarian perturbations.  The skin and stomach findings and phosphatemia 
demonstrated reversibility with 4 weeks of recovery.  Additional details are 
provided in the IB for GSK1120212 [GlaxoSmithKline Document Number 
HM2009/00151/02HM2009/00151/].
Procedures to minimize or monitor potential risks are listed below:

To reduce the risk of ocular toxicity, subjects with history of RVO, or CSR, 
subjects with predisposing factors for RVO or CSR or predisposing retinal 
pathology as determined by ophthalmologic exams are excluded.  
Ophthalmologic exams will be performed at baseline and as clinically 
warranted.

To monitor cardiac function, echocardiogram (ECHO) or multigated 
acquisition (MUGA) scans will be performed.


To reduce the risk of excessive gastrointestinal (GI) toxicity (diarrhea) and 
cutaneous toxicity (rash), subjects will be monitored closely and supportive 
care guidelines will be implemented.

1.
All subjects transitioning from parent study will begin the rollover study based on the last treatment visit completed during the parent study.  All Transition Visit 
assessments/procedures must be completed prior to the first dose of study treatment(s).  Assessments/procedures may be used to fulfill the requirements of both the parent 
study and this study.  Results from the parent study should be recorded in the eCRF as transition values.
2.
Informed consent must be obtained prior to performing any assessments or procedures for this study and before treatment with GSK1120212 is to be continued.
3.
Physical examination will be completed at the Transition Visit, Week 8 and every 12 weeks thereafter while on treatment, and at the Final Study Visit. Height (cm) and weight 
(kg) will be measured only at the Transition Visit.  
4.
Serum β–hCG pregnancy tests will be performed on female subjects of childbearing potential only at the time of transition from the parent study.
5.
Vital signs (BP, temperature, respiratory rate and pulse rate) should be taken in a semi-supine position and after the subject has rested for at least 5 minutes prior to the 
reading.  Vital signs may be measured more frequently as clinically indicated.
6.
A single 12-Lead ECG will be performed using a standard 12-lead ECG machine.  All ECGs will be taken in a supine position after resting in that position for at least 10 
minutes prior to testing.  QTc interval must not be >480 msec.  
7.
12-lead ECGs will be performed every 12 weeks (at a minimum or more frequently per local practice) for the first 2 years of treatment (including time on parent study).  After 
2 years of treatment 12-lead ECGs will be performed every 24 weeks for the duration of treatment.
8.
ECHO or MUGA scan should first be performed at Week 8 and then every 12 weeks (at a minimum or more frequently per local practice).  If LVEF decreases 20 percentage 
points, repeat testing is required within 2 weeks.  If decline is sustained, the investigator, in consultation with GSK Medical Monitor, should consider withdrawal of subject 
from the study.
9.
ECHO is only required at the Final Study Visit if an abnormal finding is reported at a prior visit.
10. Refer to Section 8.4.5 for complete list of clinical laboratory assessments to be performed.
11. Hematology and clinical chemistry laboratory assessments will be performed every 4 weeks (at a minimum or more frequently per local practice) for the first 2 years of 
treatment (including time on parent study).  After 2 years hematology and clinical chemistry laboratory assessments will be performed every 12 weeks for the duration of 
treatment.
12. Optional tumor tissue, skin or blood sample from a lesion not required for disease assessment and/or optional blood sample for cfDNA may be obtained if subject has 
provided consent.  
13. AEs/SAEs will be monitored and recorded beginning on the time of consent until 30 days after the last dose of GSK2118436.
14. All ongoing (unresolved) AEs at the time of the transition to this study will be recorded in the eCRF.
15. All concomitant medication(s) at the time of the transition to this study will be recorded in the eCRF.
16. The “Every 8 Weeks”, “Every 12 Weeks” or “Every 24 Weeks” columns are NOT a separate visit but instead a listing of assessments required to be completed every 8, 12 or

AMENDMENT 1
WHERE THE AMENDMENT APPLIES
This amendment applies to all site and countries.
Summary of Amendment Changes with Rationale
It was noted that there was inconsistent language regarding the intent of the study stated 
in the rationale and study objective sections of the protocol.  The true intent of this 
protocol is, as stated in the rationale, to allow subjects to continue on drug who are 
clinically benefitting and have an acceptable toxicity profile.  Some subjects who have 
clinically progressed (e.g., isolated progression in brain, requiring treatment with gamma 
knife) but continue to receive benefit and who are allowed as per the primary protocol to 
continue on the study treatment if both the treating physician and GSK Medical Monitor 
agree, should have continued access to the study treatment. However, as per the above 
inclusion criteria these subjects would not be allowed to roll over to open-label rollover 
study which is inconsistent with the rationale of the study.
The directions for administering GSK1120212 in a fasting state were clarified to state 
“1 hour before or 2 hours after a meal”.
Country specific requirements for Australia and France were added in the event the 
protocol is opened in these countries.  General administrative changes (i.e., authors, 
sponsor signatory, assignment of medical monitors, etc.) were also made.  List of 
references was revised to remove documents that were not cited in document but listed 
erroneously in list of references.

Description: GSK1120212 is an orally administered, potent and highly selective small 
molecule inhibitor of MEK1/MEK2 activation and kinase activity.  As monotherapy, 
GSK1120212 has shown an acceptable risk-benefit profile with encouraging efficacy in 
various oncologic settings.  This multicenter, non-randomized, open-label, rollover study 
is designed to provide continued access to GSK1120212 to eligible subjects who have 
previously participated in a GlaxoSmithKline (GSK)-sponsored GSK1120212 study 
(referred to as the parent study) and have no evidence of progressive disease as well as an 
acceptable safety profile with GSK1120212.  Subjects will be enrolled into an 
appropriate cohort based on the treatment received in their parent study.  Safety 
assessments (physical examinations, vital sign measurements, 12-lead 
electrocardiograms, echocardiograms or multiple-gated acquisition scans, clinical 
laboratory assessments, and monitoring of adverse events) will be evaluated throughout 
the study.  Clinical activity will be assessed using local standard of care imaging 
practices and the appropriate assessment criteria as determined by the investigator.

Rationale
GSK1120212 is a potent and highly selective inhibitor of MEK kinase activity.  This 
multicenter, non-randomized, open-label rollover study will provide continued access to 
GSK1120212 to subjects with solid tumors or leukemia who have previously participated 
in a GlaxoSmithKline (GSK)-sponsored GSK1120212 study and who have no evidence 
of progressive disease as well as an acceptable safety profile with GSK1120212.
Objectives
The primary objective of the study is to provide continued treatment with GSK1120212 
for subjects with solid tumors or leukemia who have previously participated in a GSK-
sponsored GSK1120212 study and who have no evidence of progressive disease as well 
as an acceptable safety profile with GSK1120212.
Study Design
This Phase II, multicenter, non-randomized, open-label, rollover study is designed to 
provide continued access to GSK1120212 to subjects with solid tumors or leukemia who 
have previously participated in a GSK-sponsored GSK1120212 study (parent study) and 
who have no evidence of progressive disease as well as an acceptable safety profile with 
GSK1120212.  Subjects will be enrolled into the appropriate cohort based upon the 
treatment received in their parent study.  Enrollment into this study will be dependent 
upon the site’s agreement to participate in this study.  It is estimated that approximately 
250 subjects will be enrolled in this study. Subjects may continue treatment in the 
rollover study until disease progression, unacceptable toxicity, withdrawal of consent, or 
commercial supply of GSK1120212 becomes available to the subject.

Section 5.7.6.1 French Specific QTc Stopping Criteria added
NEW TEXT
In line with local requirements, a subject in France that meets the QTc1 criteria 
below will have study treatment withheld:
QTcB >500 msec
1Based on average QTc value of triplicate ECGs to include manual over-read. For 
example, if an ECG demonstrates a prolonged QT interval, obtain 2 more ECGs 
over a brief period, and then use the averaged QTc values of the 3 ECGs to 
determine whether the subjects should have study treatment withheld.
If the QTc prolongation resolves to Grade 1 or baseline, the subject may be re-
started on the study treatment if the investigator and GSK Medical Monitor agree 
that the subject will benefit from further treatment.
Section 7.1 Meals and Dietary Restrictions
