Brief summary:
The goal of Phase 1 of this clinical research study is to find the highest tolerable dose of MEK162 that can be given to patients with advanced leukemia.

This is an investigational study. MEK162 is not FDA approved or commercially available. It is currently being used for research purposes only. The study doctor can explain how the study drug is designed to work.

Up to 57 patients total will take part in both phases of this study . All will be enrolled at MD Anderson.

The goal of Phase 2 of this clinical research study is to learn if MEK162 can help to control AML in older patients with advanced leukemia. The safety of this drug will also be studied.

This is an investigational study. MEK162 is not FDA approved or commercially available. It is currently being used for research purposes only. The study doctor can explain how the study drug is designed to work.

Up to 57 patients total will take part in both phases of this study. All will be enrolled at MD Anderson.

Detailed description:
Phase I:

Study Groups:

If you are found to be eligible to take part in this study, you will be assigned to a study group based on when you join this study. Up to 2 groups of 3-6 participants will be enrolled in Phase 1 of the study.

If you are enrolled in Phase 1, the dose of MEK162 you receive will depend on when you joined this study. The first group of participants will receive the lowest dose level of MEK162. The second group will receive a higher dose of MEK162 than the group before it, if no intolerable side effects were seen. This is designed to find the highest tolerable dose of MEK 162.

Participants in Phase 2 will then receive the highest tolerated dose that was found in Phase 1.

Study Drug Administration:

You will take MEK162 tablets by mouth 2 times a day (about 12 hours apart) every day with a full cup of water.

There are 4 weeks in each study cycle.

Study Visits:

On Day 1 of Cycle 1:

* You will have a physical exam.
* Blood (about 4 teaspoons) will be drawn for routine tests and blood sugar testing.

On Days 4 and 8 of Cycle 1, blood (about 4 teaspoons) will be drawn for routine tests and blood sugar testing.

Sometime during Days 13-27 of each cycle and again on Day 28 of Cycles 2 and beyond, the study staff will call you and ask about any drugs you may be taking and any side effects you may be having. The calls should last less than 10 minutes each time.

On Day 28 of Cycle 1, you will have a bone marrow aspirate and/or biopsy to check the status of the disease and for biomarker and cytogenetic testing. If bone marrow cannot be collected, blood (about 1-2 teaspoons) will be drawn for these tests.

You will have an EKG and either an ECHO or MUGA scan to check your heart function.

On Day 1 of Cycle 2 and beyond:

* You will have a physical exam.
* Blood (about 4 teaspoons) will be drawn for routine tests and blood sugar testing.
* Urine will be collected for routine tests.
* You will have an eye exam by an eye doctor.
* If you can become pregnant, blood (about 1 teaspoon) or urine will be collected for a pregnancy test.

On visits when you have blood sugar testing, you should fast for at least 8 hours before the blood draw.

On visits when you have urine collected, you will be given containers to collect your urine over 24 hours if the doctor thinks it is needed.

If it is more convenient to you, you may be able to have some of your blood draws done away from MD Anderson. The study staff will discuss this with you.

Every two or three months during your treatment, you will have an echocardiogram (ECHO) or a multigated acquisition (MUGA) scan to check your heart function.

Length of Study:

You may continue taking the study drug for as long as the doctor thinks it is in your best interest. You will no longer be able to take the study drug if the disease gets worse, if intolerable side effects occur, or if you are unable to follow study directions.

Your participation on the study will be over once you have completed the end-of-treatment visit.

End-of-Treatment Visit:

After your last dose of study drug:

* You will have a physical exam.
* Blood (about 2 teaspoons) will be drawn for routine tests
* If the doctor thinks it is needed, you will have a bone marrow aspirate and/or biopsy to check the status of the disease and for biomarker, PD, and/or cytogenetic testing. If you have already had a bone marrow aspirate and/or biopsy recently and your doctor thinks repeating it is not needed, leftover bone marrow will be used for these tests. If bone marrow cannot be collected, blood (about 1-2 teaspoons) will be drawn for these tests.
* You will have an EKG.

Phase II:

Study Groups:

If you are found to be eligible to take part in this study, you will be assigned to a study group based on when you join this study. Up to 42 participants will be enrolled in Phase 2 of the study.

Participants in Phase 1 were given a dose of MEK162 based on when they joined the study. Groups of participants were given different dose levels until the highest tolerable dose of MEK162 was found.

If you are enrolled in Phase 2, you will receive MEK162 at the highest dose that was tolerated in Phase 1.

Study Drug Administration:

You will take MEK162 tablets by mouth 2 times a day (about 12 hours apart) every day with a full cup of water.

There are 4 weeks in each study cycle.

Exploratory Objective(s) for Phase I and II (if necessary)
Phase I and II
- To explore potential molecular variations in leukemia blasts (e.g. FLT3, K-RAS, N-RAS and other known 
mutations (IDH1, IDH2, DNMT3A and others) or gene copy number in candidate genes) that may be 
predictive of differences in response to MEK 162.
The dose finding phase I portion allows for any patient with advanced AML/MDS/ALL/CMML who meets 
the eligiblity criteria as there is a possibility of activity in partients with those disorders with aberrant 
signaling along the RAF/RAS/MAPK signaling pathway although the main intention of the phase I is to 
determine whether the drug is reasonably safe.  In the phase II portion of the study Array was only 
interested in determining the activity in patients with known aberrant pathway (i.e. mutated RAS) as this 
can also be potentially used as a marker for patient selection.  Clearly, if we see significant responses in 
other patients in the phase I and particularly if it is determined that this activity is related to aberrant 
RAF/RAS/MAPK signaling, future trials will be conducted in a broader poulation and more dependent of 
demonstrating aberrant pathway signaling.
Rationale: (Be as concise as possible)
Acute myeloid leukemia (AML) is the cause of approximately 1.2% of all cancer deaths in the US with an 
annual incidence rate of 2.2 per 100,000 and approximately 9,200 new cases per year, representing 
approximately 90% of all acute leukemias in adults.The most important predictor of outcome after relapse 
is the length of the initial complete remission.3 For patients whose initial CR lasted greater than 2 years, 
repeating the initial regimen can result in a 50-60% CR rate, whereas those whose CR was less than 1 
year can expect only a 10-20% CR rate with such an approach. Prognosis of patients with refractory 
disease (i.e. no CR after two courses of induction) is quantitatively similar to those with the short first CR. 
These patients should be offered investigational therapies. In patients who relapse after an allogeneic 
transplant, the prognosis also depends on the length of CR.5,6 Donor lymphocyte infusions can produce 
remissions in some patients. Investigational agents are also indicated in this setting.
A number of risk factors such as white cell count at presentation have been identified that predict the 
length of remission and the possibility of long-term survival. However,  Cytogenetics and molecular 
features at presentation have been established as the most important factor predicting long-term 
disease-free survival. Although advancing age has been established as a negative risk factor, it is likely 
that this relates to other features such as higher incidence of poor risk Cytogenetics, (multi-drug 
resistance) MDR gene over-expression, and existence of antecedent hematological disorders. 
GSK1120212 is a potent and selective allosteric inhibitor of MEK 1 and 2 kinases. In vitro, GSK1120212 
inhibited proliferation of myeloid cell lines selectively as compared to lymphoid cell lines. A 2 part study of 
a single daily oral dosing regimen was conducted to define the recommended Phase 2 dose, evaluate 
pharmacokinetics, and assess preliminary activity in patients with relapsed or refractory AML, MDS, ALL 
or CMML. Subjects with WBC< 30,000/uL who met hepatic, renal and cardiac function criteria were 
eligible for participation. GSK1120212 was given orally, once daily in the following dose cohorts: 3mg 
loading dose followed by 1mg/day (n=3), 1mg/day without loading dose (n=1), and 2mg/day without 
loading dose (n=9). The loading dose was discontinued after cohort 1, based on findings in the phase I 
solid tumor study.
MEK162, previously named ARRY 438162, is a potent and selective allosteric, ATP non-competitive 
inhibitor of Mek1/2 that is active in inhibiting pERK and growth of BRAF mutant cancer cells in the low 
nanomolar range. MEK162 is currently being investigated as a single agent and in combination with PI3K 
or RAF inhibitors in patients with selected advanced or metastatic solid tumors, including biliary cancer, 
colorectal cancer and melanoma. Four phase I/Ib studies exploring MEK162 in combination with RAF and 
PI3K inhibitors in patients with advanced RAS/RAF and PIK3CA mutated tumors are ongoing.

Criteria for dose escalation and determination of MTD (phase I only).
This is a two-part trial to determine dosing and efficacy in leukemia patients of MEK 162.  Phase I will 
determine MEK 162 in dosing subjects with advanced leukemias.  The  phase I part of the trial has a 3+3 
dose escalation design, with 3 subjects in each cohort, using a fixed (15mg) dose escalation scheme, 
based on the occurrence of DLTs.  At the each dose level up to 6 subjects will receive MEK 162 orally 
twice a day on days 1 to 28 of a 28 day cycle.
Dose escalation (Phase I only)
-- If 0/3, 0/4, 0/5, or 0/6 evaluable subjects exhibits a DLT after one 28-day cycle, then the next subject 
will be treated at the next DL.
-- If one subject exhibits a DLT, the cohort will be expanded up to 6 subjects.
-- If one out of six evaluable subjects exhibits  a DLT, then the next subject will enroll at the next DL.
-- If more than one out of three to six evaluable subjects exhibit a DLT, then the dose level below it will be 
determined as MTD.
-- If more than 1 out of 3 to 6 evaluable subjects exhibit a DLT during the first DL then reduced dose level 
(RDL) will be investigated.
Dose escalations will proceed no sooner than 4 weeks after the last subject in the cohort has begun 
therapy.

Follow-up for dose-limiting toxicities (Phase I only)
Patients whose treatment is interrupted or permanently discontinued due to an adverse event or 
abnormal laboratory value must be followed regularly (as clinically indicated) until resolution or 
stabilization of the event, whichever comes first.
If a patient requires a dose delay of > 21 days from the intended day of the next scheduled dose, then the 
patient must be discontinued from the study.  However, the patient will continue to be followed for toxicity 
as previously described.  All patients will be followed for adverse events and serious adverse events for 
30 days following the last dose of MEK162 unless the patient received further cytotoxic chemotherapy.  In 
this case, only those adverse events and serious adverse events believed by the investigatory to have a 
causal relationship to the study medication will be captured.
Dosing modifications
For patients who do not tolerate the protocol-specified dosing schedule, dose adjustment to dose level 1 
(30 mg bid) is permitted in order to allow the patient to continue the study drug.  An individual patient may 
have one dose reduction to 30 mg bid.  This is the lowest dose permitted on the study and doses below 
30 mg bid are not permitted.  In case of toxicity, the dose should be held until resolution to grade 1 and 
then restarted at 30 mg bid.
Missed/skipped doses will not be made up (i.e the patient should not double their dose if the previous 
dose was missed).  When the toxicity that resulted in a dose reduction improves to Grade 1 or less, the

dose can be re-escalated a the investigators discretion provided there are no other concomitant toxicities.  
However,  no dose re-escalation is allowed for dose reductions that were due to left ventricular 
dysfunction.
End of Study Treatment
Patients may voluntarily withdraw from the study or be dropped from it at the discretion of the investigator 
at any time.  Patients may be withdrawn from the study if any of the following occur:
Pregnancy

Non-compliance

If such withdrawal occurs, or if the patient fails to return for visits, the investigator must determine the 
primary reason for a patient's premature withdrawal from the study and record this information.  Patients 
may be withdrawn from the study prematurely for one of the following reasons:
Adverse event(s)

Abnormal laboratory value(s)

Abnormal test procedure result(s)

Protocol violation

Subject withdrew consent

Lost to follow-up

Administrative problems

Death

New cancer therapy

Disease progression

Treatment duration completed as per protocol

Study evaluation completion
As a general rule, if a patient discontinues study drug and later is  prematurely withdrawn from the study, 
the reasons for study evaluation completion may include the following:
Protocol violation

Subject withdrew consent

Lost to follow-up

Administrative problems

Death

New cancer therapy

Clinically significant disease progression

For patients who are lost to follow-up, the investigator should show "due diligence" by documenting in the 
source documents steps taken to contact the patient, e.g., dates of telephone calls, registered letters, etc.

Is this an NCI-Cancer Therapy Evaluation Protocol (CTEP)?
No
Is this an NCI-Division of Cancer Prevention Protocol (DCP)?
No
Statistical Considerations:
The primary endpoint is the overall response (CR+CRi) after one or two cycles of treatment. The 
historical data suggested the overall response rate is 5%. With the assumption that the improved overall 
response rate to be 20%, it is estimated that a total of 42 evaluable patients will yield 91% power at a 
significance level of 5% based on chi-square test. 
The overall response (CR+CRi) denoted as OR, and toxicity (DLT definition in phase I), denoted as TOX, 
will be monitored simultaneously by Bayesian stopping boundaries calculated based on beta-binomial 
distribution. Independence is assumed between OR and TOX. There are no historical data available. The 
current regimen will be considered promising if the OR rate is at least 20% and the TOX rate is below 
30%.  The prior probabilities of OR and TOX for the regimen are modeled by beta distributions (Beta(0.4, 
1.6) and Beta(0.6, 1.4), respectively).   Denoting the probabilities of the OR rate and TOX by 
 the following decision criteria will be applied:
Patients will be monitored by a cohort size of 6 according to the following stopping boundaries for OR and 
toxicity. If the number of responses required for moving the trial to next stage has not been achieved, the 
patient enrollment will be halted until enough responses observed. The design software Multc Lean 
Desktop (version 2.1) developed by the Department of Biostatistics at M. D. Anderson Cancer Center 
(MDACC) was used to generate the futility/toxicity stopping boundaries and the OC table.

post-treatment safety data of any kind would be excluded from the safety population.
Per protocol population: consists of all randomized patients who received at least one dose of the 
study drug and had no major protocol violations.  The per protocol patient population will be identified 
prior to database lock.
MTD population:  consists of all patients who either received study drug and had sufficient safety 
evaluations or discontinued due to unacceptable toxicity and have received at least approximately 75% 
doses of first cycle of therapy.  The MTD patient population will be identified prior to database lock.
Efficacy population: consists of all patients treated at MTD who meet the requirements for 
recruitment into the expansion phase. The primary endpoint is overall response rate (ORR).   The 
ORR will be estimated along with the exact 95% confidence interval.

INTRODUCTION 
1.1 
Background 
1.1.1 
Overview of acute myeloid leukemia (AML) 
 
Acute myeloid leukemia (AML) is the cause of approximately 1.2% of all cancer deaths in the US with an annual incidence 
rate of 2.2 per 100,000 and approximately 9,200 new cases per year, representing approximately 90% of all acute leukemias 
in adults.1 The incidence rises with age; genetic predisposition, drug and environmental exposures and occupational factors 
may have a role in its genesis.2 Standard therapy of AML includes remission induction with regimens consisting of ara-C and 
an anthracycline followed by consolidation with similar regimens.1 The most important predictor of outcome after relapse is 
the length of the initial complete remission.3 For patients whose initial CR lasted greater than 2 years, repeating the initial 
regimen can result in a 50-60% CR rate, whereas those whose CR was less than 1 year can expect only a 10-20% CR rate 
with such an approach.1 Prognosis of patients with refractory disease (i.e. no CR after two courses of induction) is 
quantitatively similar to those with the short first CR.1 These patients should be offered investigational therapies.1,4 In 
patients who relapse after an allogeneic transplant, the prognosis also depends on the length of CR.5,6 Donor lymphocyte 
infusions can produce remissions in some patients.7 Investigational agents are also indicated in this setting.4 
 
A number of risk factors such as white cell count at presentation have been identified that predict the length of remission and 
the possibility of long-term survival. However, cytogenetics and molecular features at presentation have been established as 
the most important factor predicting long-term disease-free survival.8,9 Although advancing age has been established as a 
negative risk factor, it is likely that this relates to other features such as higher incidence of poor risk cytogenetics, (multi-
drug resistance) MDR gene over-expression, and existence of antecedent hematological disorders.10-12 
1.1.2 
MEK inhibitors in AML and other hematological malignancies  
 
GSK1120212 is a potent and selective allosteric inhibitor of MEK 1 and 2 kinases. In vitro, GSK1120212 inhibited 
proliferation of myeloid cell lines selectively as compared to lymphoid cell lines. A 2 part study of a single daily oral dosing 
regimen was conducted to define the recommended Phase 2 dose, evaluate pharmacokinetics, and assess preliminary activity 
in patients with relapsed or refractory AML, MDS, ALL or CMML. Subjects with WBC< 30,000/uL who met hepatic, renal 
and cardiac function criteria were eligible for participation. GSK1120212 was given orally, once daily in the following dose 
cohorts: 3mg loading dose followed by 1mg/day (n=3), 1mg/day without loading dose (n=1), and 2mg/day without loading 
dose (n=9). The loading dose was discontinued after cohort 1, based on findings in the phase I solid tumor study.  
 
Fourteen subjects (10 with AML, 2 MDS transformed to AML, 1 MDS, 1 ALL) entered the trial. Eight were male, and 
median age was 65 years (range 33 to 85). Pharmacokinetic analysis showed that, upon repeat dosing, GSK1120212 exposure 
increased in a dose-proportional manner, had a small peak:trough ratio of approximately 4 and an effective half-life of 
approximately 7.7 days. Steady state concentrations were reached by day 15. Both single and repeat dose pharmacokinetics 
of GSK1120212 appeared to be similar to a phase I study in patients with solid tumors. Systemic exposure exceeded 
concentrations that inhibited in vitro leukemic cell proliferation. At the 2mg/day dose level (n=9), drug-related adverse events 
were diarrhea (7 overall; 6-Grade 1/2, 1-Grade 3), rash (3-Grade 1/2), fatigue (4-Grade 1/2), visual changes (3 Grade 1/2). 
One subject experienced a Grade 2 reversible serous retinopathy associated visual changes which resolved after drug 
discontinuation. One dose limiting toxicity was seen in a subject with disease-related Grade 4 thrombocytopenia and 
pneumonia who experienced a Grade 5 cerebrovascular accident possibly related to drug. One subject in the 2mg/day cohort 
achieved a CR; peripheral blast count was reduced from 30% at baseline to 0% and bone marrow blast count was reduced 
from 50% at baseline to 3%. During this time, platelet count increased from 48K to a maximum of 276K. Initial salutary 
effect was seen after 2 weeks on therapy and duration of CR was 4 weeks bone marrow blast count was 3% and 5%, 
respectively, at the beginning and end of the 4 week CR duration.  
 
MSC1936369 is a selective non-competitive inhibitor of MEK1/2 with anti-proliferative activity in leukemia cell lines and in 
human tumor xenograft models with activation of mitogen-activated protein kinase (MAPK) signaling. The preliminary data 
of the safety run-in part of the phase II trial, in which the primary objective was to determine the maximum tolerated dose

(MTD) for different dosing schedules (S) has been presented. Methods: MSC1936369 was administered orally twice per day 
(BID), either on days 1–5, 8–12, 15–19 and 22–26 (S1) or on days 1–21 (S2) of a 28-day cycle. Dose escalation within each 
S followed a modified Fibonacci scheme with 3+3 cohorts. PK samples and peripheral blood leukemia blasts for the 
measurement of phosphorylated extracellular signal-regulated kinase (pERK) were collected for all pts. Results: 48 pts have 
been treated, 25 in S1 (8–42 mg BID) and 23 in S2 (8–60 mg BID). Pt characteristics, treatment exposure, and safety signals 
were similar in both Ss. The median age was 67 years (range 22–80), 66% were male and the Eastern Cooperative Oncology 
Group Performance Status was 0/1/2 in 25%/58%/17% of pts, respectively. Underlying HMs were: acute myeloid leukemia 
(AML, n=41), myelodysplastic syndrome (MDS, n=3) and other (n=4). Cytogenetics were known for 42/44 pts with MDS 
(n=3) and AML (n=39): 3 were favorable, 21 intermediate and 18 unfavorable. RAS mutation was present in 5 pts (not 
reported in others), of whom 2 also carried a FLT3 mutation. Six additional pts had a FLT3 mutation. The median duration of 
treatment was 3.7 weeks (range 0.1–77). The MTD has not been reached in either S. One dose-limiting toxicity (DLT) of 
grade 2 angioedema was seen in S1 at 42 mg BID. The most common non-hematological adverse events (AEs): infections 
(56%), diarrhea (46%), skin rash (38%), nausea (27%), pyrexia (25%), peripheral edema (21%), dizziness (21%), aspartate 
aminotransferase increase (21%) and transient visual disorders (with underlying serous retinal detachment in most cases) 
(21%). Plasma concentrations increased proportionally with dose. Sustained pERK inhibition during the dosing period was 
observed in blasts and lymphocytes starting at 23 mg BID. Transient clearance or 50% decrease of blasts in bone marrow and 
peripheral blood have been detected in 6 pts (MDS n=2, AML n=4), 2 RAS mutated. 
1.1.3 
Overview of MEK162 
MEK162, previously named ARRY 438162, is a potent and selective allosteric, ATP non-competitive inhibitor of Mek1/2 
that is active in inhibiting pERK and growth of BRAF mutant cancer cells in the low nanomolar range. MEK162 is currently 
being investigated as a single agent and in combination with PI3K or RAF inhibitors in patients with selected advanced or 
metastatic solid tumors, including biliary cancer, colorectal cancer and melanoma. Four phase I/Ib studies exploring MEK162 
in combination with RAF and PI3K inhibitors in patients with advanced RAS/RAF and PIK3CA mutated tumors are 
ongoing.  
The dose of 45 mg BID is considered safe and efficacious and is the dose used in an ongoing Phase 2 study in cancer 
patients. The maximum tolerated dose (MTD) of MEK162 is 60 mg BID.  
Non-clinical experience 
The biological activity of MEK162 has been evaluated in vitro (both enzymatic and cell culture assays) and in vivo in mouse 
xenograft studies. MEK162 potently inhibits Mek1/2 in both biochemical assays using purified protein, and in cells. 
MEK162 has demonstrated robust, but selective, growth inhibitory activity in a wide variety of cancer cell lines. In a 
collection of ~500 genetically annotated cell lines, MEK162 showed anti-proliferative activity preferentially in cells 
harboring activating mutations of the MAP kinase pathway (e.g. BRAF, NRAS and KRAS), and in particular, activating 
mutations in BRAF and NRAS. In vivo, MEK162 has demonstrated dose dependent tumor growth inhibition in various 
subcutaneous tumor transplants harboring BRAFV600E mutations (HT29, COLO205, A-375) as well as activating mutations in 
both NRAS (Hs. 944T) and KRAS (MiaPaCa2, A549, LoVo, Calu6). These data suggest that MEK162 may provide a 
potential therapeutic benefit in cancer indications, harboring these mutations, including melanoma. 
In animals, exposure (AUC) and Cmax generally increased in a dose proportional manner. The plasma clearance is low 
(range: ~2 to 8 mL/min/kg) and the mean plasma half-life values ranges from 2 to 9 hours. MEK162 has moderate membrane 
permeability and is a substrate of P-gP and BCRP. MEK162 exhibited high plasma protein binding in vitro (> 96%, except 
dog 84%) and is predicted to have good stability with respect to hepatic metabolism. Nonclinical in vitro and in vivo data 
indicated that MEK162 is metabolized by multiple routes but primarily by glucuronidation pathways (mainly via UGT1A1, 
1A3 and 1A9) and to a lesser extent by oxidation pathways (mainly via CYP1A2 and 2C19). The formation of active 
metabolite AR00426032 is mediated primarily by CYP1A2 with minor contributions from other cytochrome P450 enzymes 
(CYPs). MEK162 potently inhibits CYP2B6 and weakly inhibits CYP1A2 and 2C9. It is not considered a time dependent 
inhibitor of CYP1A2, CYP2C9, CYP2D6 and CYP3A. In vitro evidence also suggests that MEK162 could induce CYP3A. 
Acute, subchronic, chronic, reproductive toxicity, genotoxicity and phototoxicity studies were completed to support the 
chronic administration of MEK162 to adult cancer patients. The clinical toxicity of MEK inhibitors has been more similar to 
that of monkeys than rats and include gastro-intestinal intolerance and diarrhea, rash, central serous retinopathy (only seen in 
humans) and retinal vein occlusion (rarely seen in humans). In vitro and in vivo phototoxicity studies conducted in mice 
indicate that MEK162 has a very low risk of weak phototoxic potential at therapeutic doses. Furthermore, there has been no

evidence of phototoxicity or photosensitivity in humans being treated with MEK162 for cancer or for rheumatoid arthritis. 
This includes 450 patients who have received at least one dose of MEK162 and is based on data as of 29 February 2012. 
Given the embryo-lethal effects seen in rats and rabbits and the teratogenic effects seen in rabbits, MEK162 should not be 
used in pregnant women and women of child-bearing potential must be advised to use highly effective contraception 
methods. 
A detailed summary of available preclinical data is provided in the Investigator’s Brochure. 
Clinical experience 
As of the data-cutoff date of February 29, 2012, a total of 450 patients and healthy volunteers have received at least 1 dose of 
MEK162 and been evaluated for safety, including 70 healthy volunteers, 164 patients with rheumatoid arthritis and 216 
patients with advanced cancer. A total of 175 and 41patients with advanced solid tumors have been treated with MEK162 as 
single agent and in combination with PI3K or RAF inhibitors, respectively. Patients with advanced cancer have received or 
are currently receiving MEK162 (either as a single agent or in combination with PI3K or RAF inhibitors) at doses of 30 to 80 
mg BID in the following studies: [ARRAY-162-111] (90 patients with advanced biliary or colorectal cancer), 
[CMEK162X2201] (81 patients with NRAS or BRAF metastatic melanoma), [CMEK162X1101] (4 Japanese patients with 
advanced solid tumors), [CMEK162X2101] and [CMEK162X2102] (11 and 21 patients, respectively with advanced solid 
tumors who have BRAF or RAS mutations) and [CMEK162X2103] (9 patients with advanced solid tumors). 
The most frequent treatment-related AEs in patients receiving MEK162 for advanced cancer were rash, dermatitis acneiform, 
nausea, diarrhea, peripheral edema, vomiting, fatigue and increase in blood creatine phosphokinase.  
Seventy-two out of 90 (87%) patients treated with MEK162 as a single agent in the ARRAY-162-111 study and 58/81 (72%) 
patients in the CMEK162X2201 study developed rash. Across both trials, 78% were assessed as related to MEK162. Most 
were Grade 1/2 (mild/moderate) and improved or resolved with treatment (topical or oral antibiotics, topical or oral steroids). 
In most cases, MEK162 was continued during the treatment of the rash, however, a dose interruption and/or dose reduction 
was required in some patients. Grade 3/4 events of rash occurred in eight patients, one of which was a dose limiting toxicity 
(DLT) at the 80 mg BID dose level in the ARRAY-162-111 study. In the combination studies of MEK162 with other PI3K or 
RAF inhibitors, rash was also one of the most commonly reported AEs.  
Retinal events have occurred in 17 out of 90 (19%) patients treated in ARRAY-162-111 study. At dose levels of 45 mg BID 
(2 patients with Grade 1 and 2 patients with Grade 2 events), 60 mg BID (2 patients with Grade 1 and 9 patients with Grade 2 
events) and 80 mg BID MEK162 (1 patient with Grade 1 and 1 patient with G3 events). Approximately 71% of these patients 
reported visual symptoms associated with the retinal abnormalities. Symptoms have included flashing lights/floaters, color 
variations, blurred vision, and seeing shapes upon opening the eye. Retinal events have been described as “leaky” type 
detachment with collections of subneurosensory fluid which is best visualized on optical coherence tomography. No “tear” 
type detachments have been reported. The retinal events have included central serous retinopathy (CSR), retinal deposits, 
retinopathy, chorioretinopathy and venous stasis retinopathy. To date, these retinal events have been reversible in all patients 
upon discontinuation or dose reduction of MEK162. In most patients, MEK162 was held until resolution of all signs and 
symptoms. In two patients in the 45 mg BID cohort, the dose was reduced without holding treatment and there was no 
reoccurrence of the event. Low grade (Grade 1/2) CSR-like events were also reported by 17/81 patients in the single agent 
CMEK162X2201 study and 3/3 patients in the Japanese single agent CMEK162X1101 study. Low grade (Grade 1/2) CSR-
like events were also reported in all combination studies of MEK162 with PI3K or RAF inhibitors. 
Adverse events of reversible elevations of creatine kinase (CK) were reported in 12/90 (13%) patients in the ARRAY-162-
111 study. Additionally, clinical laboratory results have shown that 64/90 (71%) patients had an elevated CK after starting 
study therapy. Most elevations were Grade 1/2. Eight patients had Grade 3 elevations and one patient had a Grade 4 
elevation. Most of the CK elevations were asymptomatic and reversible. In the CMEK162X2201 study, increase of the blood 
CK has been reported in 24/81 (30%) patients, including Grade 3/4 events reported by 16/81 patients. Of those, the event was 
reported as related to MEK162 treatment in 28% of patients. Reversible elevations of CK have also been reported in the 
combination studies of MEK162 with PI3K or RAF inhibitors. 
As of the data-cutoff date, 32 (15%) out of 216 patients with advanced cancer treated with MEK162 (as a single agent or in 
combination with PI3K or RAF inhibitors) experienced liver related adverse events (19 patients Grade 1 or 2, 12 patients 
Grade 3, 1 patient Grade 4). Twenty three of 32 patients had liver metastases at baseline. The reported adverse events 
included elevations of aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyltransferase 
(GGT), alkaline phosphatase (AP), bilirubin, hepatic pain, ascites, cytolytic hepatitis, bile duct obstruction, cholangitis,

jaundice and cholestatic jaundice. Of Note, one case of acute liver failure with fatal outcome, possibly related to MEK162 
has been reported. 
In study CMEK162X2201, one case of cardiac failure, possibly related to MEK162, has been reported at a starting dose of 60 
mg BID.  In addition, a non-serious decrease in cardiac ejection fraction Grade 3 (baseline 50% to 24%) was also reported in 
the same cohort. While a relationship to MEK162 could not be ruled out, this patient had a number of confounding factors, 
including significant hypothyroidism and hypertension. Additional review of the MUGA/Echo EF values (as of February 28, 
2012) revealed an additional patient treated at 45 mg BID experienced a Grade 3 drop in ejection fraction (baseline 58% to 
39%).  In addition, there were two instances of emerging Grade 2 decrease (one at 45 mg BID and one at 60 mg BID cohort).  
Of note, while these two patients had decreases from baseline in EF, their EF remained above the lower limit of normal. 
In study [CMEK162X2102] (a phase Ib open-label dose escalation study of MEK162 plus RAF265) two serious and one non 
serious case of decrease left ventricular ejection fraction were reported. All cases improved after interruption or 
discontinuation of study drug.  RAF265 is a potent inhibitor of RAF, VEGFR-2, and platelet-derived growth factor receptor-
beta (PDGFR-β), although speculative, it is possible that the combination with RAF265 is increasing the risk of reduced 
LVEF by its anti-angiogenic activity.   
Elevated CK was associated with the administration of MEK162, as described above. It cannot be excluded that in a small 
percentage of patients with advanced cancer, MEK162 is associated with liver transaminase elevations. No other apparent 
trends in clinical laboratory parameters, vital signs or electrocardiograms (ECGs) were associated with the administration of 
MEK162.  
 
For further information regarding clinical experience with MEK162, refer to the Investigator’s Brochure. 
Pharmacokinetics 
In healthy subjects, MEK162 exposure (as quantified by Cmax and AUC) tended to increase in a dose-proportional manner 
following single and multiple doses over a dose range of 5 to 80 mg QD for single dose and 5 to 60 mg QD for multiple 
doses. One additional cohort received 20 mg BID for 14 consecutive days. The mean apparent half-life was 7 to 8 hours, and 
the mean apparent time of maximum plasma drug concentration (Tmax) was 1.18 hrs. Plasma drug concentrations by 12 hours 
post-dose   approached the LLOQ of 5 ng/mL in many subjects. These initial PK data supported a BID dosing regimen of 
MEK162 as appropriate for maintaining sufficient plasma concentrations over the dosing interval at steady state in order to 
consistently inhibit the primary target. The AR00426032 metabolite represented < 13% of the parent drug in plasma and < 
5% of the parent drug was excreted renally. Accumulation of MEK162 was < 40% following QD dosing and < 75% 
following BID dosing. 
 
Pre-clinical studies in mice support that >50% inhibition in pERK in HT-29 tumors for 24 hours is optimal for significant 
tumor growth inhibition. This degree of sustained pERK inhibition was best achieved with BID dosing at lower doses (< 10 
mg/kg/dose) or QD dosing at higher doses (> 30 mg/kg/dose). Given that little to no drug was apparent in plasma at 24 hours 
post-dose (at low doses) in the pre-clinical xenograft studies, a BID dosing regimen  was considered to be the most reliable 
murine schedule to maintain plasma concentrations for optimal efficacy. Therefore, a BID dosing regimen (e.g., 45 mg) 
should provide sufficient exposure with acceptable safety and adequate continuous pharmacological inhibition of the primary 
target. 
 
The initial evaluation of the PK of MEK162 in patients with advanced cancer (ARRAY-162-111 and CMEK162X2201) at 
the doses evaluated to date (30 to 80 mg BID) indicated that both the plasma concentration-time profiles and PK parameters 
were similar to  those in healthy subjects, as well as in patients with rheumatoid arthritis. The inter-subject variability for 
AUC and Cmax was ~40%. The mean active metabolite-to-parent ratio was less than 25% across all study days and dose levels 
tested. Steady-state is reached by Day 15 and accumulation of MEK162, as estimated using non-compartmental methods, is 
around 50% (or 1.5 fold). 
 
To integrate all the available PK information, a preliminary population PK model describing the PK of MEK162 was built 
using data from 68 subjects from the Array and Novartis studies. The model suggests that the PK can be adequately described 
using linear kinetics (2 compartmental open model with first order absorption and a lag time). There was extensive tissue 
distribution and clearance of MEK162 estimated as 17 L/h. For the typical individual, steady-state is reached by Day 15 and 
accumulation of MEK162 is around 70% (or 1.7 fold).

Overview of comparator/combination drugs 
 
GSK1120212 is a potent and selective allosteric inhibitor of MEK 1 and 2 kinases. In vitro, GSK1120212 inhibited 
proliferation of myeloid cell lines selectively as compared to lymphoid cell lines. A 2 part study of a single daily oral dosing 
regimen was conducted to define the recommended Phase 2 dose, evaluate pharmacokinetics, and assess preliminary activity 
in patients with relapsed or refractory AML, MDS, ALL or CMML. Subjects with WBC< 30,000/uL who met hepatic, renal 
and cardiac function criteria were eligible for participation. GSK1120212 was given orally, once daily in the following dose 
cohorts: 3mg loading dose followed by 1mg/day (n=3), 1mg/day without loading dose (n=1), and 2mg/day without loading 
dose (n=9). The loading dose was discontinued after cohort 1, based on findings in the phase I solid tumor study. 
  
Fourteen subjects (10 with AML, 2 MDS transformed to AML, 1 MDS, 1 ALL) entered the trial. Eight were male, and 
median age was 65 years (range 33 to 85). Pharmacokinetic analysis showed that, upon repeat dosing, GSK1120212 exposure 
increased in a dose-proportional manner, had a small peak:trough ratio of approximately 4 and an effective half-life of 
approximately 7.7 days. Steady state concentrations were reached by day 15. Both single and repeat dose pharmacokinetics 
of GSK1120212 appeared to be similar to a phase I study in patients with solid tumors. Systemic exposure exceeded 
concentrations that inhibited in vitro leukemic cell proliferation. At the 2mg/day dose level (n=9), drug-related adverse events 
were diarrhea (7 overall; 6-Grade 1/2, 1-Grade 3), rash (3-Grade 1/2), fatigue (4-Grade 1/2), visual changes (3 Grade 1/2). 
One subject experienced a Grade 2 reversible serous retinopathy associated visual changes which resolved after drug 
discontinuation. One dose limiting toxicity was seen in a subject with disease-related Grade 4 thrombocytopenia and 
pneumonia who experienced a Grade 5 cerebrovascular accident possibly related to drug. One subject in the 2mg/day cohort 
achieved a CR; peripheral blast count was reduced from 30% at baseline to 0% and bone marrow blast count was reduced 
from 50% at baseline to 3%. During this time, platelet count increased from 48K to a maximum of 276K. Initial salutary 
effect was seen after 2 weeks on therapy and duration of CR was 4 weeks bone marrow blast count was 3% and 5%, 
respectively, at the beginning and end of the 4 week CR duration.  
 
MSC1936369 is a selective non-competitive inhibitor of MEK1/2 with anti-proliferative activity in leukemia cell lines and in 
human tumor xenograft models with activation of mitogen-activated protein kinase (MAPK) signaling. We present the 
preliminary data of the safety run-in part of the phase II trial, in which the primary objective is to determine the maximum 
tolerated dose (MTD) for different dosing schedules (S). Methods: MSC1936369 was administered orally twice per day 
(BID), either on days 1–5, 8–12, 15–19 and 22–26 (S1) or on days 1–21 (S2) of a 28-day cycle. Dose escalation within each 
S followed a modified Fibonacci scheme with 3+3 cohorts. PK samples and peripheral blood leukemia blasts for the 
measurement of phosphorylated extracellular signal-regulated kinase (pERK) were collected for all pts. Results: 48 pts have 
been treated, 25 in S1 (8–42 mg BID) and 23 in S2 (8–60 mg BID). Pt characteristics, treatment exposure, and safety signals 
were similar in both Ss. The median age was 67 years (range 22–80), 66% were male and the Eastern Cooperative Oncology 
Group Performance Status was 0/1/2 in 25%/58%/17% of pts, respectively. Underlying HMs were: acute myeloid leukemia 
(AML, n=41), myelodysplastic syndrome (MDS, n=3) and other (n=4). Cytogenetics were known for 42/44 pts with MDS 
(n=3) and AML (n=39): 3 were favorable, 21 intermediate and 18 unfavorable. RAS mutation was present in 5 pts (not 
reported in others), of whom 2 also carried a FLT3 mutation. Six additional pts had a FLT3 mutation. The median duration of 
treatment was 3.7 weeks (range 0.1–77). The MTD has not been reached in either S. One dose-limiting toxicity (DLT) of 
grade 2 angioedema was seen in S1 at 42 mg BID. The most common non-hematological adverse events (AEs): infections 
(56%), diarrhea (46%), skin rash (38%), nausea (27%), pyrexia (25%), peripheral edema (21%), dizziness (21%), aspartate 
aminotransferase increase (21%) and transient visual disorders (with underlying serous retinal detachment in most cases) 
(21%). Plasma concentrations increased proportionally with dose. Sustained pERK inhibition during the dosing period was 
observed in blasts and lymphocytes starting at 23 mg BID. Transient clearance or 50% decrease of blasts in bone marrow and 
peripheral blood have been detected in 6 pts (MDS n=2, AML n=4), 2 RAS mutated. 
1.2 
Study rationale/purpose 
 
Cellular proliferation, differentiation, and death are regulated by a number of extracellular molecules such as cytokines and 
hormones, as well as intercellular interactions mediated by neighboring cell surface antigens. These effectors mediate gene 
transcription either directly or indirectly by activating intracellular signaling pathways, which in turn activate appropriate 
cellular machinery. Cell-surface receptors that convert external stimuli into intracellular signals are pivotal in this signaling 
process. They activate intracellular pathways either through their inherent enzymatic function or as a result of their

   ---2013-0116 
 
association with other catalytic proteins. Indeed, most growth factors and cytokines bind these receptors and exert their 
function through their activation, commonly by phosphorylation. 
 
 Normal hematopoiesis is dependent on intricately regulated signaling cascades that are mediated by cytokines and their 
receptors. Orderly function of these pathways leads to the generation of appropriate constellation of hematopoietic cells, and 
their abnormal activation results in neoplastic transformation, impaired apoptosis, and uncontrolled proliferation. Cytokines 
function in a redundant and pleiotropic manner; different cytokines can exert similar effects on the same cell type, and any 
particular cytokine can have several differing biological functions . This complexity of function is a result of shared receptor 
subunits as well as overlapping downstream pathways culminating in activation of common transcription factors.  
The serine/threonine MAPKs, which include the Ras-Raf-MEK-ERK pathway, the p38 family of kinases, and the JNK 
(SAPK) family, are activated by upstream signals and mediate effects on inflammation, cell growth, cell cycle progression, 
cell differentiation, and apoptosis. The Ras family of proteins belongs to the large superfamily of GTPases that localize to the 
inner surface of the plasma membrane. Ras proteins play a pivotal role in a number of signaling pathways mediated by RTKs 
and other receptors. Ligand binding to these receptors initiates the autophosphorylation of specific tyrosine residues in their 
cytoplasmic domain and creates phosphotyrosyl-binding sites for adapter proteins such as Shc and Grb2, which in turn recruit 
guanine nucleotide exchange factors and thereby initiate Ras activation.  
Once induced, Ras activates Raf serine/threonine kinase, which then phosphorylates MAPK kinases (otherwise known as 
MEKs).  These in turn activate MAPKs or ERKs. which in turn move to the nucleus where they phosphorylate and activate 
nuclear transcription factors such as Elk-1. ERKs were initially described as a novel family of protein kinases that, when 
activated, produced proliferative stimuli ERKs that can also activate other kinases such as RSKs (also known as MAPK-
activated protein kinases), which are involved in cell-cycle regulation and apoptosis. ERK-activated RSK kinase catalyzes the 
proapoptotic protein Bad and suppresses Bad-mediated apoptosis. Similarly, the Ras-Raf-MEK-ERK cascade modulates 
cellular proliferation by regulating the activity of several proteins, including cell-cycle regulators (e.g. cyclin D1, p21waf1/cip1, 
p27kip1, and cdc25A) and transcription factors (e.g., c-Myc; Ref.) 
Constitutive activation of the ERK pathway is frequently seen in human cancers and is often due to over-expression or 
mutation of upstream receptor tyrosine kinases, increased expression of growth factor ligands, or mutational activation of Ras 
and its downstream effectors. In human malignancies, activating Ras mutations are common, having been identified in about 
30% of cancers. These mutations are found with high incidence in several solid tumor types including pancreatic (90%), 
colon (45%), thyroid (60%), non-small-cell lung cancer (NSCLC) (35%) as well as AML (30%). MEKs on the other hand, 
have not been identified as oncogene products in human malignancies. They are, however, present at a crucial point of 
convergence that integrates signal inputs from a variety of protein kinases through Ras. In addition, MEKs are very restricted 
in their substrate specificity, with ERK being the sole known substrate. 
 
Sustained MAPK activation plays an important role in a number of hematological 
malignancies. Activation of MEK resulting in overexpression of p44/42MAPK results in constitutive MAPK activation in the 
most AML cases. Internal tandem duplication of the Flt3 receptor is observed in up to one third of AML samples and also 
results in constitutive MAPK activation and the autonomous growth of myeloid cell lines. Direct evidence for a 
leukemogenic role of the MAPK pathway is derived from the observation that a conditionally active form of MEK1 confers 
cytokine independence to hematopoietic cells. It has been also demonstrated that small molecule inhibitors as well as 
interfering RNAs disrupting the signal transduction in MEK/MAPK pathway cause antiproliferative and proapoptotic 
consequences in AML cell lines and primary AML blasts, while relatively sparing normal hematopoietic progenitors, thus 
providing the preclinical rationale for the development of MEK/MAPK-targeted therapeutic strategies in AML. 
 
Based on the above data, MEKs are important targets for the development of drugs for patients with hematological 
malignancies. The phase I dose escalation part will be performed in subjects with refractory hematological malignancies and 
no effective standard therapies available. The MEK/ERK/MAPK pathway is deregulated in all of those malignancies but the 
level of activation that render a tumor “dependent” is unknown. Therefore, the MEK inhibitor has a potential to be active in 
these diseases but no predictive models exist. 
 
GSK1120212 is a potent and selective allosteric inhibitor of MEK 1 and 2 kinases. In vitro, GSK1120212 inhibited 
proliferation of myeloid cell lines selectively as compared to lymphoid cell lines. A 2 part study of a single daily oral dosing 
regimen was conducted to define the recommended Phase 2 dose, evaluate pharmacokinetics, and assess preliminary activity 
in patients with relapsed or refractory AML, MDS, ALL or CMML. Subjects with WBC< 30,000/uL who met hepatic, renal

and cardiac function criteria were eligible for participation. GSK1120212 was given orally, once daily in the following dose 
cohorts: 3mg loading dose followed by 1mg/day (n=3), 1mg/day without loading dose (n=1), and 2mg/day without loading 
dose (n=9). The loading dose was discontinued after cohort 1, based on findings in the phase I solid tumor study.

 STUDY OBJECTIVES 
 
Primary Trial Objective(s) for Phase I and II 
Phase 1. 
-To determine the MTD/RP2D (recommended phase 2 dose) of MEK162 in subjects with advanced leukemias. 
Phase II 
-To assess the anti-leukemic activity of MEK 162 (overall response including CR and CRi) in older subjects with newly 
diagnosed KRAS/NRAS mutant poor prognosis AML, who are not candidates for intensive chemotherapy. 
 
Secondary Trial Objective(s) for Phase I and II 
Phase I 
-To determine the safety of MEK 162 in patients with relapsed and/or refractory leukemias. 
-To assess the PK of MEK 162 in patients with leukemias. 
-To assess anti-leukemic activity (CR and CRi) of MEK 162 in patients with leukemia. 
Phase II 
-To determine the safety and tolerability of MEK 162 in older subjects with newly 
diagnosed KRAS/NRAS mutant poor prognosis AML. 
 
Exploratory Objective(s) for Phase I and II (if necessary) 
Phase I and Phase II 
-To explore potential molecular variations in leukemia blasts (e.g.FLT3, K-RAS, N-RAS and other known mutations (IDH1, 
IDH2, DNMT3A and others) or gene copy number in candidate genes) that may be predictive of differences in response to 
MEK 162. 
 
The dose finding Phase I portion allows for any patient with advanced AML/MDS/ALL/CMML who meets the eligibility 
criteria as there is a possibility of activity in patients with those disorders with aberrant signaling along the RAF/RAS/MAPK 
signaling pathway although the main intention of the phase I is to determine whether the drug is reasonably safe.  In the 
phase II portion of the study Array was only interested in determining the activity in patients with known aberrant pathway 
(i.e. mutated RAS) as this can also be potentially used as a marker for patient selection.  Clearly, if we see significant 
responses in other patients in the phase I and particularly if it is determined that this activity is related to aberrant 
RAF/RAS/MAPK signaling, future trials will be conducted in a broader population and more dependent of demonstrating 
aberrant pathway signaling. 
3 
STUDY DESIGN 
This is a two-part trial to determine dosing and efficacy in leukemia patients with MEK 162.  Phase I will determine MEK 
162 dosing in subjects with advanced leukemias.  The phase I part of the trial has a 3+3 dose escalation design, with 3 
subjects in each cohort, using the 50% dose escalation scheme, based on the occurrence of DLTs. 
At the each dose level subjects will receive MEK 162 orally twice a day on  
- 
Days 1 to 28 of a 28-day cycle  
 
Prior to advancing dose levels, a cohort summary will be completed and submitted to the Clinical Research Monitor (IND 
Office) 
 
Patients will continue therapy as long as they are receiving clinical benefit. 
 
The MTD/RP2D determined by Phase I will be used in an open label, Phase II part of MEK 162 in older subjects with newly 
diagnosed KRAS/NRAS mutant poor prognosis AML, who are not candidates for intensive chemotherapy.

administration. Males with female partners of childbearing potential and female subjects of childbearing potential must 
therefore be willing to use highly effective methods of contraception throughout the study and for 1 month after study drug 
discontinuation.  
 
Highly effective contraception methods include: 
 
Total abstinence or 
 
Male or female sterilization 
 
Combination of any two of the following (a+b or a+c or b+c) 
a. Use of oral, injected, or implanted hormonal methods of contraception 
b. Placement of an intrauterine device (IUD) or intrauterine system (IUS) 
c. Barrier methods of contraception: condom or occlusive cap (diaphragm or cervical/vault caps) with spermicidal 
foam/gel/film/cream/vaginal suppository 
 
For the purposes of this trial, childbearing potential is defined as “All female subjects after puberty unless they are post-
menopausal for at least two years, surgically sterile or sexually inactive”. 
 
Pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive 
hCG laboratory test (> 5 mIU/mL). 
 
Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, are not allowed to 
participate in this study UNLESS they are using highly effective methods of contraception throughout the study and for 1 
month after study drug discontinuation. Highly effective contraception methods include: 
 
Total abstinence or  
 
Male or female sterilization 
 
Combination of any two of the following (a+b or a+c or b+c) 
d. Use of oral, injected, or implanted hormonal methods of contraception 
e. 
Placement of an intrauterine device (IUD) or intrauterine system (IUS) 
f. 
Barrier methods of contraception: condom or occlusive cap (diaphragm or cervical/vault caps) with spermicidal 
foam/gel/film/cream/vaginal suppository 
 
Post-menopausal women are allowed to participate in this study. Women are considered post-menopausal and not of child 
bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. 
age appropriate, history of vasomotor symptoms) or six months of spontaneous amenorrhea with serum Follicle-Stimulating

Hormone (FSH) levels > 40 mIU/mL or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal 
ligation at least six weeks prior to screening. In the case of oophorectomy alone, only when the reproductive status of the 
woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential. 
 
Sexually active males must use a condom during intercourse while taking the drug and for 1month  after stopping treatment 
and should not father a child in this period. A condom is required to be used also by vasectomized men in order to prevent 
delivery of the drug via seminal fluid.

STUDY TREATMENT 
Study drug will be administered as a flat-fixed dose, and not by body weight or body surface area, with a glass of water and 
irrespective of food. Prescribed bid doses should be taken 12 ± 2 hrs apart. Complete dosing instructions will be provided to 
study patients and will include the minimum times between doses and instructions for missed doses. Patients will also be 
instructed not to chew or crush caplets of study drug. Patients will be instructed to return unused study drug to the site at each 
visit. 
If a patient vomits at any time after dosing, the dose of study drug should not be re-administered. Doses of study drug omitted 
for AEs or any other reason should not be replaced or made up later in the day, or at the end of the dosing period.  
The site personnel will train the patient and/or his/her caregiver on dosing procedures for the drug. Patients will be supplied 
with a sufficient number of caplets for the number of doses to be taken prior to the next scheduled visit.

Treating the patient 
4.3.1 
Study drug/study treatment/active control administration 
MEK162 will be dispensed by the pharmacist or designee at the Investigator’s institution. Patients will receive MEK162 on 
an outpatient basis unless the patient is inpatient for other reasons. Patients must be instructed to bring any empty study drug 
bottles and unused study medication with them at the next visit for drug accountability and compliance checks. When 
returned, unused study medication will be destroyed in accordance with institutional policy. 
Records of drug formulation, batch number, bottles dispensed, received and returned must be recorded in the pharmacy study 
file. 
4.3.2 
Criteria for dose escalation and determination of MTD (Phase I only).  
 
This is a two-part trial to determine dosing and efficacy in leukemia patients of MEK 162.  Phase I will determine MEK 162 
in dosing subjects with advanced leukemias.  The phase I part of the trial has a 3+3 dose escalation design, with 3 subjects in 
each cohort, using a fixed (15 mg) dose escalation scheme, based on the occurrence of DLTs. 
At the each dose level up to 6 subjects will receive MEK 162 orally twice a day on days 1 to 28 of a 28-day cycle.  
4.3.3 
Dose escalation (Phase I only).  
 
- 
If 0/3, 0/4, 0/5, or 0/6 evaluable subjects exhibits a DLT after one 28-day cycle, then the next subject will be treated 
at the next DL.  
-  
If one subject exhibits a DLT, the cohort will be expanded up to 6 subjects.  
-  
If one out of six evaluable subjects exhibits a DLT, then the next subject will enroll at the next DL.  
-  
If more than one out of three to six evaluable subjects exhibit a DLT, then the dose level below it will be determined 
as MTD.  
-  
If more than 1 out of 3 to 6 evaluable subjects exhibit a DLT during the first DL then reduced dose level (RDL) will 
be investigated.  
Dose escalations will proceed no sooner than 4 weeks after the last subject in the cohort has begun therapy.

However, prophylactic treatment may be initiated in all patients at the dose level where these toxicities have been 
observed and in all further patients if at least 1 patient has experienced skin toxicity or nausea/ vomiting ≥ 
CTCAE Grade 3 or if at least 2 patients experienced skin toxicity or nausea/ vomiting ≥ CTCAE Grade 2.  
However anti-emetics may be applied for treatment if the patient has experienced nausea/vomiting CTCAE

 b For any CTCAE Grade 4 or any CTCAE Grade 2 hepatic toxicity that does not resolve within 7 days to 
CTCAE Grade ≤ 1 (or CTCAE Grade ≤ 2 if liver infiltration with tumor present), an abdominal CT scan has to 
be performed to assess if it is related to disease progression.  
c Refers to total bilirubin  
4.3.4 
Follow-up for dose-limiting toxicities (Phase I only).  
Patients whose treatment is interrupted or permanently discontinued due to an adverse event or abnormal laboratory value 
must be followed regularly (as clinically indicated) until resolution or stabilization of the event, whichever comes first.  
If a patient requires a dose delay of > 21 days from the intended day of the next scheduled dose, then the patient must be 
discontinued from the study. However, the patient will continue to be followed for toxicity as previously described. All 
patients will be followed for adverse events and serious adverse events for 30 days following the last dose of MEK162 unless

Page 20 
Oncology Clinical Trial Protocol (Version No. 08 –10-15-2015)

the patient received further cytotoxic chemotherapy.  In this case, only those adverse events and serious adverse events 
believed by the investigatory to have a causal relationship to the study medication will be captured. 
4.3.5 
Dosing modifications 
For patients who do not tolerate the protocol-specified dosing schedule, dose adjustment to dose level 1 (30 mg bid)is 
permitted in order to allow the patient to continue the study drug. An individual patient may have one dose reduction to 30 
mg bid (Table 4-4). This is the lowest dose permitted on the study and doses below 30 mg bid are not permitted. In case of 
toxicity, the dose should be held until resolution to grade 1 and then restarted at 30 mg bid. 
Missed/skipped doses will not be made up (i.e. the patient should not double their dose if the previous dose was missed). 
When the toxicity that resulted in a dose reduction improves to Grade 1 or less, the dose can be re-escalated at the 
investigators discretion provided there are no other concomitant toxicities. However, no dose re-escalation is allowed for 
dose reductions that were due to left ventricular dysfunction. 
In general, doses should not be reduced or interrupted for Grade 1 AEs unless the AE is a new visual or ocular AE (see Table 
4-5), but treatment to control symptoms should be provided as appropriate, if applicable. If visual changes or new ocular 
findings are assessed as not related to study drug after ophthalmologic evaluation, then study drug can be resumed at the 
same, previous dose. All adverse events should be followed up weekly or as clinically appropriate until stabilization or 
resolution. 
Skin toxicity (acne, rash, dermatitis acneiform, etc.), visual changes (related to CSR), nausea, diarrhea and asymptomatic, 
reversible elevation of CPK have been associated with MEK162 administration. For skin toxicity, institutional standard of 
care treatment should be initiated promptly. Treatment of rash may include, but is not limited to, topical or oral antibiotics, 
topical or oral anti-inflammatories, topical or oral corticosteroids and oral anti-histamines 
Management of diarrhea should be as per institutional standard of care. 
Furthermore, please refer to Appendix 3 and Appendix 4 for additional supportive care guidelines for the management of 
MEK162 induced skin toxicity and diarrhea respectively. Visual changes should be graded according to CTCAE version 4.03 
as described below.

Other concomitant medications 
The Investigator should instruct the patient to notify the study site of any new medications he/she takes after the start of the 
study drug.  
All medications and significant non-drug therapies (including herbal medicines, physical therapy and blood transfusions) 
taken within 2 weeks prior to first dose of study drug must be recorded in the electronic medical record.  
All medications (other than study drug) and significant non-drug therapies (including herbal medicines, physical therapy and 
blood transfusions) administered after the patient starts treatment with study drug, and any changes in dosing must be 
recorded in the electronic medical record.  
Patients taking concomitant medication chronically should be maintained on the same dose and dose schedule throughout the 
study period, as medically feasible.  
Permitted concomitant therapy requiring caution and/or action 
The solubility of MEK162 is pH dependent and a 10-fold decrease in solubility is observed between pH 1 and 2. Patients 
receiving concomitant treatments that could potentially modify the gastric pH (i.e. PPI) should be instructed to take them at 
least two hours after the administration of MEK162. 
MEK162 has been identified to be primarily metabolized by UGT1A1 in vitro. It is advised that inhibitors and inducers of 
UGT1A1 should be taken with caution when co-administered with MEK162. Patients should be closely monitored for the 
occurrence of adverse events. Please refer to Table 6-10 for a list of these known drugs but this list may not be exhaustive.

MEK162 potently inhibits CYP2B6  Ki of 1.67 µM  Based on these in vitro findings, MEK162 may inhibit the metabolic 
clearance of co-medications metabolized by CYP2B6, if sufficiently high concentrations are achieved in vivo. At 45 mg BID, 
the maximum concentrations achieved in plasma are normally <1.5 μM so the risk of drug interaction is limited. Caution 
should be used in patients receiving concomitant treatment with other drugs that are substrates of this enzyme.

2 Substrates with narrow therapeutic index (NTI): Drugs whose exposure-response indicates that increases in their exposure levels by the 
concomitant use of potent inhibitors may lead to serious safety concerns (e.g., Torsades de Pointes). 
This list of CYP substrates was compiled from the Indiana University School of Medicine’s “Clinically Relevant” Table; from the FDA’s 
“Guidance for Industry, Drug Interaction Studies” and from the University of Washington’s Drug Interaction Database. The following 
website may be further useful as a reference to avoid potential drug-drug interactions: http://medicine.iupui.edu/clinpharm/ddis/table.asp. 
Drugs with a known, a conditional or a possible risk to induce Torsade de Pointes (TdP) should be used with caution. Patients 
receiving such medications must be carefully monitored for potentiating of toxicity due to any individual concomitant 
medication, and may require dose titration of the drug substance. For further information, please visit the website of the 
QTdrugs.org Advisory Board of the Arizona CERT. 
Patients will be advised to contact the study personnel (research nurse or physician) whenever they are to be started on a new 
medication in order for agents from above list are excluded and alternates are recommended. 
4.3.7 
Prohibited concomitant therapy 
 
Other investigational therapies must not be used while the patient is on the study with the exception of hydroxyurea, 
which is allowed during the first cycle of therapy only. 
 
Anticancer therapies (including chemo- or biologic-therapy or palliative radiation therapy, covering >25% of the red 
bone marrow reserve, and surgery) other than the study treatments must not be given to patients while the patient is on 
the study. If such therapeutic measures are required for a patient then the patient must be discontinued from the study. 
4.3.8 
Hormonal contraception 
Oral contraceptives are allowed but should be used in conjunction with a barrier method of contraception due to the unknown 
effect of study drug interactions. 
4.3.9 
Study drug discontinuation 
In general, doses should not be reduced or interrupted for Grade 1 AEs unless the AE is a new visual or ocular AE (see Table 
4-5), but treatment to control symptoms should be provided as appropriate, if applicable. If visual changes or new ocular

findings are assessed as not related to study drug after ophthalmologic evaluation, then study drug can be resumed at the 
same, previous dose. 
Patients requiring treatment interruptions of >21 days must be discontinued. 
All patients must have evaluations for 28 days after the last dose of study treatment. Patients lost to follow up should be 
recorded. Patients who discontinue study drug before completing the study should be scheduled for a visit as soon as 
possible, at which time all of the assessments listed for the final visit will be performed. At a minimum, all patients who 
discontinue study treatment, including those who refuse to return for a final visit, will be contacted for safety evaluations 
during the 28 days following the last dose of study drug. 
If patients refuse to return for these visits or are unable to do so, every effort should be made to contact them or a 
knowledgeable informant by telephone 
Patients who discontinue study drug should be considered withdrawn from the study after the final visit assessments are 
performed or when it is clear that the patient will not return for these assessments. 
4.4 
End of Study Treatment 
Patients may voluntarily withdraw from the study or be dropped from it at the discretion of the investigator at any time. 
Patients may be withdrawn from the study if any of the following occur:  
 
Pregnancy 
 
Non-compliance 
If such withdrawal occurs, or if the patient fails to return for visits, the investigator must determine the primary reason for a 
patient’s premature withdrawal from the study and record this information. Patients may be withdrawn from the study 
prematurely for one of the following reasons: 
 
Adverse event(s) 
 
Abnormal laboratory value(s) 
 
Abnormal test procedure result(s) 
 
Protocol violation 
 
Subject withdrew consent 
 
Lost to follow-up 
 
Administrative problems 
 
Death 
 
New cancer therapy  
 
Disease progression 


4.5 
Study evaluation 
completion 
As a general rule, if a patient discontinues study drug and later is prematurely withdrawn from the study, the reasons for 
study evaluation completion may include the following: 
 
Protocol violation 
 
Subject withdrew consent 
 
Lost to follow-up 
 
Administrative problems 
 
Death 
 
New cancer therapy 
 
Clinically significant disease progression

6 SAFETY MONITORING 
6.1       Serious adverse event reporting 
 
Serious Adverse Event Reporting (SAE) for M. D. Anderson-Sponsored IND Protocols 
 
An adverse event or suspected adverse reaction is considered “serious” if, in the view of either the investigator or the 
sponsor, it results in any of the following outcomes: 
 
Death 
 
A life-threatening adverse drug experience – any adverse experience that places the patient, in the view of the initial 
reporter, at immediate risk of death from the adverse experience as it occurred. It does not include an adverse experience 
that, had it occurred in a more severe form, might have caused death. 
 
Inpatient hospitalization or prolongation of existing hospitalization 
 
A persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions. 
 
A congenital anomaly/birth defect. 
 
Important medical events that may not result in death, be life-threatening, or require hospitalization may be considered a 
serious adverse drug experience when, based upon appropriate medical judgment, they may jeopardize the patient or 
subject and may require medical or surgical intervention to prevent one of the outcomes listed in this definition. Examples 
of such medical events include allergic bronchospasm requiring intensive treatment in an emergency room or at home, 
blood dyscrasias or convulsions that do not result in inpatient hospitalization, or the development of drug dependency or 
drug abuse (21 CFR 312.32). 
 
 
Important medical events as defined above, may also be considered serious adverse events. Any important medical 
event can and should be reported as an SAE if deemed appropriate by the Principal Investigator or the IND Sponsor, IND 
Office. 
 
All events occurring during the conduct of a protocol and meeting the definition of a SAE must be reported to the 
IRB in accordance with the timeframes and procedures outlined in “The University of Texas M. D. Anderson Cancer 
Center Institutional Review Board Policy for Investigators on Reporting Unanticipated Adverse Events for Drugs and 
Devices”. Unless stated otherwise in the protocol, all SAEs, expected or unexpected, must be reported to the IND Office, 
regardless of attribution (within 5 working days of knowledge of the event). 
 
All life-threatening or fatal events, that are unexpected, and related to the study drug, must have a written report 
submitted within 24 hours (next working day) of knowledge of the event to the Safety Project Manager in the IND Office.  
 
Unless otherwise noted, the electronic SAE application (eSAE) will be utilized for safety reporting to the IND Office 
and MDACC IRB.  
 
Serious adverse events will be captured from the time of the first protocol-specific intervention, until 30 days after 
the last dose of drug, unless the participant withdraws consent. Serious adverse events must be followed until clinical 
recovery is complete and laboratory tests have returned to baseline, progression of the event has stabilized, or there has 
been acceptable resolution of the event.  
 
Additionally, any serious adverse events that occur after the 30 day time period that are related to the study treatment 
must be reported to the IND Office. This may include the development of a secondary malignancy. 
 
The following SAEs are not subject to expedited reporting, but would still be included in the annual report via the SAE 
log.

Protocol No. CABC123D4567 
 
a) Infection or cytopenias leading to hospitalization or prolongation of hospitalization  
b) Disease progression leading to death, life-threating AE, hospitalization or  prolongation of hospitalization, or 
disability. 
 
Reporting to the FDA: 
 
Serious adverse events will be forwarded to FDA by the -IND Sponsor (Safety Project Manager IND Office) 
according to 21 CFR 312.32 
 
It is the responsibility of the PI and the research team to ensure serious adverse events are reported according to the 
Code of Federal Regulations, Good Clinical Practices, the protocol guidelines the sponsor’s guidelines, and Institutional 
Review Board policy. 
 
Investigator Communication with Supporting Companies: 
Information about all serious adverse events will be collected and recorded on the eSAE form that is used by MDACC for 
safety reporting to the IND Office and MDACC IRB. Such information will be provided to Array Drug Safety by faxing 
the information contained in the exemplar Serious Adverse Event Form, which is appended to the Protocol using fax 
number (303) 386-1516. To ensure patient safety each serious adverse event must also be reported to Array within 24 
hours of learning of its occurrence. A serious adverse event is an undesirable sign, symptom or medical condition which: 
1. is fatal or life-threatening 
2. required or prolonged hospitalization 
3. results in persistent or significant disability/incapacity  
4. constitutes a congenital anomaly or a birth defect 
5. is medically significant, may jeopardize the subject and may require medical or surgical intervention to prevent one 
of the outcomes listed above. 
Events not considered to be serious adverse events are hospitalizations for the:  
 
routine treatment or monitoring of the studied indication, not associated with any deterioration in condition. 
 
treatment, which was elective or pre-planned, for a pre-existing condition that did not worsen 
 
treatment on an emergency, outpatient basis for an event not fulfilling any of the definitions of serious given above 
and not resulting in hospital admission.  
Pregnancy, although not itself a serious adverse event, should also be reported on a serious adverse event form or 
pregnancy form and be followed up to determine outcome, including spontaneous or voluntary termination, details of 
birth, and the presence or absence of any birth defects or congenital abnormalities. 
Any serious adverse event occurring after the patient has provided informed consent, has started taking the study 
medication, and until 4 weeks after the patient has stopped study participation must be reported. This includes the period 
in which the study protocol interferes with the standard medical treatment given to a patient (e.g. treatment withdrawal 
during washout period, change in treatment to a fixed dose of concomitant medication). The period after discontinuing 
study drug may be extended if there is a strong suspicion that the drug has not yet been eliminated. 
6.1.1 
Reporting responsibility 
The principal investigator has the obligation to report all serious adverse events to the FDA, IRB, and Array in accordance 
with institutional guidelines. 
6.1.2 
Reporting procedures 
The investigator must complete the eSAE form that is used by MDACC for safety reporting to the IND Office and 
MDACC IRB and Array SAE coversheet in English, assess the relationship to study treatment and send the initial 
completed eSAE form and Array SAE coversheet by fax 1-303-386-1516 within 24 hours to the Array Drug Safety 
Department.  The investigator must then ensure that the form and coversheet are accurately and fully completed with 
follow-up information and fax those to Array Drug Safety within 2 to 3 calendar days for deaths or life-threatening events 
and 15 calendar days for other serious adverse events. The original and the duplicate copies of the eSAE form, ArraySAE 
coversheet, and the fax confirmation sheet must be kept with the case report forms at the study site.  


 
Confidential 
Page 31 
Oncology Clinical Trial Protocol (Version No. 08) 
 
Protocol No. CABC123D4567 
 
Follow-up information should describe whether the event has resolved or continues, if and how it was treated, whether the 
blind was broken or not, and whether the patient continued or discontinued study participation. The eSAE form, Array 
SAE coversheet, and fax confirmation sheet must be retained. Pregnancy follow-up should describe the outcome of the 
pregnancy, including any voluntary or spontaneous termination, details of the birth, and the presence or absence of any 
congenital abnormalities or birth defects. 
6.1.3 
Pregnancies 
Any pregnancy that occurs during study participation should be reported. To ensure patient safety each pregnancy must 
also be reported toArraywithin 24 hours of learning of its occurrence. The pregnancy should be followed up to determine 
outcome, including spontaneous or voluntary termination, details of birth, and the presence or absence of any birth 
defects, congenital abnormalities or maternal and newborn complications. 
6.1.4 
Adverse events of special interest 
 
As a result of signals observed from previous studies, several AEs requiring a close follow-up were identified. For each 
category, selected AEs similar in nature, will be identified and grouped: 
 
Ocular/Visual Events 
 
Retinal Vein Occlusion 
 
Rash and related events 
 
Peripheral/generalized edema/anasarca 
 
Serum CK elevation 
 
Cardiac failure related events 
 
Hepatic events 
7 STATISTICAL METHODS AND DATA ANALYSIS 
 
This is a two-part trial to determine dosing and efficacy in leukemia patients of MEK 162.  Phase I will determine MEK 
162 dose (MTD) in subjects with advanced leukemias.  The phase I part of the trial has a 3+3 dose escalation design, with 
3 to 6 subjects in each cohort, using the 50% dose escalation scheme, based on the occurrence of DLTs.  Patients will be 
entered sequentially to each dose level  If none of the first 3 patients at a dose level experience dose-limiting toxicity 
(DLT), new patients may be entered at the next higher dose level.  If 1 of 3 patients experience DLT, up to 3 more 
patients are started at that same dose level.  If 1 of 6 experience DLT, then new patients may be entered at the next higher 
dose level.  If 2 or more experience DLT, no further patients are started at that dose.  The MTD is the highest dose level in 
which <2 patients of 6 develop DLT. 
 
The sample size is envisaged to be 15 subjects (assuming no need for replacement of subjects in the MTD analysis set), 
comprising 2 dose levels (DLs) with a maximum of 6 subjects in each plus 3 additional subjects enrolled at the MTD. 
 
At the each dose level subjects will receive MEK 162 orally twice a day on  
- 
Days 1 to 28 of a 28-day cycle  
 
The MTD determined by Phase I will be used in an open label, Phase II part of MEK 162 in older subjects with newly 
diagnosed KRAS/NRAS mutant poor prognosis AML who are not candidates for intensive chemotherapy.

7.1     Efficacy  
The method of Thall, Simon and Estey [1995] will be used for futility and toxicity monitoring for this study. The primary 
endpoint is the overall response (CR+CRi) after one or two cycles of treatment. The historical data suggested the overall 
response rate is 5%. With the assumption that the improved overall response rate to be 20%, it is estimated that a total of 
42 evaluable patients will yield 91% power at a significance level of 5% based on chi-square test. The overall response 
(CR+CRi) denoted as OR, and toxicity (DLT definition in phase I), denoted as TOX, will be monitored simultaneously by 
Bayesian stopping boundaries calculated based on beta-binomial distribution.  Independence is assumed between OR and 
TOX.  There are no historical data available.  The current regimen will be considered promising if the OR rate is at least 
20% and the TOX rate is below 30%.  The prior probabilities of OR and TOX for the regimen are modeled by beta 
distributions (Beta(0.4, 1.6) and Beta(0.6, 1.4), respectively).  Denoting the probabilities of the OR rate and TOX by {θOR, 
θTOX}, the following decision criteria will be applied: 
 
1) 
stop if Prob { θOR < 0.2 | data} > 0.98, and 
2) 
stop if Prob { θTOX > 0.3 | data} > 0.85 
 
Patients will be monitored by a cohort size of 6 according to the following stopping boundaries for OR and toxicity.  If the 
number of responses required for moving the trial to next stage has not been achieved, the patient enrollment will be 
halted until enough responses observed.  The design software Multc Lean Desktop (version 2.1) developed by the 
Department of Biostatistics at M. D. Anderson Cancer Center (MDACC) was used to generate the futility/toxicity 
stopping boundaries and the OC table.

7.2      Populations for analysis 
ITT population: consists of all patients who received at least one dose of study drug.. 
Safety population: consists of all enrolled patients who received at least one dose of study drug and had at least one post-
baseline safety assessment.  
Please note: the statement that a patient had no adverse events (on the Adverse Event CRF) constitutes a safety 
assessment. Patients who have received at least one dose of study drug but who have no post-treatment safety data of any 
kind would be excluded from the safety population. 
Per protocol population: consists of all randomized patients who received at least one dose of the study drug and had no 
major protocol violations. The per protocol patient population will be identified prior to database lock. 
MTD population: consists of all patients who either received study drug and had sufficient safety evaluations or 
discontinued due to unacceptable toxicity and have received at least approximately 75% doses of first cycle of therapy. 
The MTD patient population will be identified prior to database lock. 
Efficacy population: consists of all patients treated at MTD who meet the requirements for recruitment into the 
expansion phase. The primary endpoint is overall response rate (ORR).  The ORR will be estimated along with the exact 
95% confidence interval.

APPENDIX 1 – CLINICAL RESPONSE CRITERIA FOR ACUTE LEUKEMIA 
 
 
 
9.1 
APPENDIX 2 - CLINICAL 
RESPONSE CRITERIA FOR ACUTE LEUKEMIA  
International Working Group (IWG) consensus criteria for treatment response in AML 
(modified).  
Morphological Complete Remission (CR):  
 
Normalization of the peripheral blood absolute neutrophil count > 1.0x10
9
/L, platelets > 
than 100x10
9
/L no residual evidence of extramedullary disease and bone marrow aspirate with ≤ 
5% blasts, no blasts with Auer rods(AML only).  
Morphological Complete Remission with incomplete blood count recovery (CRi):  
 
Same as CR but without normalization of the peripheral blood absolute neutrophil and 
platelet count  
Partial Remission (PR):  
 
Normalization of the peripheral blood absolute neutrophil count >1.0x109/L, platelets > 
than 100x109/L, and at least a 50% decrease in the percentage of marrow aspirate blasts to 5-25% 
, or marrow blasts <5% with Auer rods (AML only).  
Progressive disease (PD): may be defined as ONE of the following:  
 
>50% increase in peripheral blood or bone marrow blasts from best assessment with 
minimum threshold of 20% blasts in the marrow or 1.0x109/L blasts in peripheral blood.  
 
Development of biopsy proven extramedullary leukemia (if the subject has 
extramedullary disease at baseline, then PD will be defined by blood and marrow criteria or if 
new sites of extramedullary disease appear).  
 
If subject who present with an initial marrow blast percentage sufficiently high to 
preclude the ability to base disease progression on a>50% increase in marrow blast percentage, 
disease progression should be based on peripheral blood criteria or development of 
extramedullary leukemia as above.  
Stable disease:  
 
Subjects who fail to achieve CR CRi or PR and who do not have criteria for PD will be 
defined as having the stable disease. If the subject dies prior to response assessment at the end of 
Cycle 1, then they will be classified as “indeterminate”.

Page 37 
Oncology Clinical Trial Protocol (Version No. 08) 
 
Protocol No. CABC123D4567 
 
 
 
Relapse from CR or CRi:  
 
Reappearance of leukemic blasts in the peripheral blood; or> 5% blasts in the bone 
marrow not attributable to another cause (e.g. recovery of normal cells following treatment –
induced aplasia or use of growth factors) OR  
 
Appearance or reappearance of extramedullary disease.  
 
If there are no circulating blasts and no extramedullary disease and the bone marrow blast 
percentage is >5% but <20%, then a repeat bone marrow performed at least 7 days after the first 
marrow examination and documenting bone marrow blast percentage >5% is necessary to 
establish relapse.  
 
Cytogenetic Responses  
Complete cytogenetic response: An abnormal clone is detected in all metaphases prior to 
treatment and only normal metaphases are observed in all metaphases following treatment.  
Partial cytogenetic response: An abnormal clone is detected in all metaphases prior to treatment 
and the post-treatment sample has 50% or fewer abnormal metaphases compared to the pre-
treatment value.  
Cytogenetic non-response: An abnormal clone is detected in all metaphases prior to treatment and 
neither complete nor partial cytogenetic response is observed in post-treatment specimens  
Specimens with normal cytogenetic results before treatment will not be evaluated for cytogenetic 
response. The method used to determine cytogenetic response will be standard metaphase 
cytogenetics.

9.2 
Appendix 3: Recommended 
Guidelines for the management of MEK162 induced skin toxicity  
Clinical judgment and experience of the treating physician should guide the management plan of 
each patient, however, the following options are recommended. 
Prophylactic treatment for skin toxicity is recommended. Prophylactic supportive therapy for skin 
toxicity may be initiated 24 hours prior to the first treatment with MEK162 or as needed. Apply 
topical agents to the mostly common affected areas such as  face, scalp, neck, upper chest, upper 
back. 
 
Non oily sunscreen (PABA free, SPF ≥ 15, UVA/UVB protection)Topical steroid, 
preferably mometasone cream (i.e. Elocon®) 
 
Topical erythromycin evening (i.e.Eryaknen®) 
 
Offer doxycycline (100 mg daily) for the first 2-3 weeks of study drug administration. 
Topical agents should be applied on a daily basis starting on Day 1 of study treatment or 24 hours 
prior to first treatment, and more often as needed. 
Effective medications also include antihistamines, other topical corticosteroids, other topical 
antibiotics and low-dose systemic corticosteroids  
The treatment algorithm based on CTCAE grade is as follows: 
Mild Rash (CTCAE Grade 1) 
 
Consider prophylactic rash treatment as described above if not already started 
 
Topical mometasone cream or other topical corticosteroid and/or topical erythromycin 
(2%) or other topical antibiotics are recommended. 
 
The patient should be reassessed after 2 weeks or sooner if rash worsens. 
Moderate Rash (CTCAE Grade 2) 
 
Although there has been no evidence of phototoxicity or photosensitivity in patients being 
treated with MEK162, doxycycline (or minocycline as second option) should be used with careful 
UV protection (i.e., avoid direct exposure to sunlight, use sunglasses, use sunscreen, etc.).  
The treatment recommendation is: topical erythromycin or clindamycin (1%) plus mometasone or 
pimecrolimus (1% cream) plus oral antibiotics: oxytetracycline (125 mg twice daily) or oral 
lymecycline (408 mg once daily) or other antibiotics (doxycycline 100 mg BID or minocycline 
(50 to 100 mg QD). 
Severe Rash (CTCAE Grade 3-4) 
CTCAE Grade 3 
 
Modality 1: In addition to the interventions recommended for moderate rash, consider oral 
prednisolone at a dose of 0.5 mg/kg.  Upon improvement, taper the dose in a stepwise manner (25 
mg for 7 days, subsequently decreasing the dose by 5 mg/day every day to 0). 
 Modality 2: In addition to the interventions recommended for moderate rash, consider oral 
isotretinoin (0.3 to 0.5 mg/kg) (Lacouture et al 2011) 


 
Confidential 
Page 39 
Oncology Clinical Trial Protocol (Version No. 08) 
 
Protocol No. CABC123D4567 
 
CTCAE Grade 4 
 
Immediately discontinue the patient from study drug and treat the patient with oral and 
topical medications (see recommendation CTCAE Grade 3). 
In Addition: 
It is strongly recommended that patients who develop rash/skin toxicities receive symptomatic 
treatment for management of the specific sign or symptom of the toxicity. 
 
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, emollients that are  mild pH 5 neutral are recommended. 
 
For paronychia, antiseptic bath and local potent corticosteroids in addition to oral 
antibiotics are recommended and, if no improvement is seen, a dermatologic or surgical 
consultation is recommended. 
 
For infected lesions, bacterial and fungal culturing followed by the appropriate culture-
driven systemic or topical antibiotics is indicated.

Appendix 4: Guidelines for the management of MEK162 induced diarrhea 
Proactively investigate for occurrence of diarrhea 
Educate patient 
1. 
Remind patients at each visit to contact the site immediately upon the first sign of loose 
stool or symptoms of abdominal pain. Additionally, at each study visit, each patient should be 
specifically questioned regarding any experience of diarrhea or diarrhea-related symptoms. If 
symptoms were experienced by the patient, then the site should question the patient regarding the 
actions taken for these symptoms and re-instruct as necessary. 
2. 
In addition to dietary modification, the patients should be instructed on early warning 
signs (e.g. severe cramping → severe diarrhea, fever with diarrhea → infection). 
3. 
Patients should be instructed on what to report to the investigator if possible (i.e. number 
of stools, stool composition, stool volume) and how to report symptoms of life-threatening 
sequelae (e.g. fever or dizziness on standing). 
Anti-diarrhea therapy 
In order to effectively manage diarrhea and mitigate the escalation in severity or duration of 
diarrhea, patient education as well as proper management of diarrhea is mandatory.  
Management of diarrhea should be instituted at the first sign of abdominal cramping, loose stools 
or overt diarrhea. All concomitant therapies used for treatment of diarrhea must be recorded on 
the Concomitant Medications eCRF. It is recommended that patients be provided loperamide 
tablets. It is mandatory that patients are instructed on the use of loperamide on the first day of 
MEK162 dosing in order to manage signs or symptoms of diarrhea at home. In addition to the 
MEK162 induced diarrhea dosing guidelines in Table 6-6 of the protocol, these instructions 
should be provided at each visit and the site should ensure that the patient understands the 
instructions.  
Explain the frequency of diarrhea and its relationship to NCI CTCAE grading. 
Determine if diarrhea is complicated versus uncomplicated. 
Rule out other or concomitant causes. 
These may include: 
 
Infection by Candida spp, Salmonella spp., Clostridium difficile, Campylobacter spp. 
Giardia, Entamoeba, Cryptosporidium which can lead to opportunistic infections in 
mmunosuppressed patients, 
 
Medications (diarrheogenic agents; laxatives, antacids, etc.) 
 
Malabsorption/lactose intolerance 
 
Fecal impaction, partial bowel obstruction 
For uncomplicated Grade 1 to Grade 2 diarrhea 
 
Stop all lactose-containing products and alcohol and eat frequent small meals that include 
bananas, rice, applesauce or toast)

 
Stop laxatives, bulk fiber (i.e. Metamucil®) and stool softeners (e.g. docusate sodium; 
Olace®) 
 
Stop high-osmolar food supplements such as Ensure® Plus and Jevity® Plus (with fiber) 
 
Drink 8 to 10 large glasses of clear liquids per day (e.g. water, Pedialyte®, Gatorade® or 
broth) 
 
Consider administration of standard dose of loperamide: initial administration 4 mg, then 
2 mg every 4 hours (maximum of 16 mg/day) or after each unformed stool. 
 
Discontinue loperamide after 12-hours diarrhea-free (Grade 0) interval. 
 
If uncomplicated Grade 1 to Grade 2 diarrhea persists for more than 24 hours, escalate to 
high dose loperamide: 2 mg every 2 hours (max. of 16 mg/day) or after each unformed stool. 
Note: Oral antibiotics may be started as prophylaxis for infections under the discretion of the 
physician. 
 If uncomplicated Grade 1 to Grade 2 diarrhea persists after 48 hours total treatment with 
loperamide, discontinue loperamide and begin a second-line agent which can be an opiate (opium 
tincture or paregoric), or budesonide 
For complicated Grade 1 to Grade 2 diarrhea or Grade 3 to 4 diarrhea 
 
The patient must call the investigator immediately 
 
If loperamide has not been initiated, initiate loperamide immediately. Initial 
administration 4 mg, then 2 mg every 4 hours (maximum of 16 mg/day) or after each unformed 
stool. 
 
Administer IV fluids and electrolytes as needed. In case of severe dehydration, replace 
loperamide by octreotide. 
 
Monitor/Continue IV fluids and antibiotics as needed. Intervention should be continued 
until the patient is diarrhea free for at least 24 hours. 
 
Hospitalization may need to be considered.

2. STUDY PROCEDURES
Screening Tests
Signing this consent form does not mean that you will be able to take part in this 
study.  You will have the following screening tests to help the doctor decide if you 
are eligible:
You will have a physical exam.

Blood (about 6 teaspoons) and urine will be collected for routine tests.

You will have a bone marrow aspiration and/or biopsy to check the status of 

the disease and for biomarker, pharmacodynamic (PD), and cytogenetic 
testing.  To collect a bone marrow aspirate and biopsy, an area of the hip or 
other site is numbed with anesthetic, and a small amount of bone marrow and 
bone is withdrawn through a large needle.  Biomarkers are found in the blood 
and tissue and may be related to your reaction to the study drug.  Genetic 
biomarkers will also be studied.  PD testing measures how the level of study 
drug in your body may affect the disease.  Cytogenetic testing looks at how 
genetic changes to cells may affect how the disease may react to the study 
drug.  If you have already had a bone marrow aspirate and/or biopsy recently 
and your doctor thinks repeating it is not needed, leftover bone marrow will be 
used for these tests.  If bone marrow cannot be collected, blood (about 1-2 
teaspoons) will be drawn for these tests.
You will have an electrocardiogram (EKG) and either an echocardiogram 

(ECHO) or a multigated acquisition (MUGA) scan to check your heart 
function. 
You will have an eye exam by an eye doctor.

If you can become pregnant, blood (about 1 teaspoon) or urine will be 

collected for a pregnancy test.  To take part in this study, you must not be 
pregnant.
The study doctor will discuss the screening test results with you.  If the screening 
tests show that you are not eligible to take part in the study, you will not be enrolled.  
Other treatment options will be discussed with you.
Study Groups
If you are found to be eligible to take part in this study, you will be assigned to a 
study group based on when you join this study.  Up to 2 groups of 3-6 participants 
will be enrolled in Phase 1 of the study.
If you are enrolled in Phase 1, the dose of MEK162 you receive will depend on when 
you joined this study.  The first group of participants will receive the lowest dose 
level of MEK162.  The second group will receive a higher dose of MEK162 than the 
group before it, if no intolerable side effects were seen.  This is designed to find the 
highest tolerable dose of MEK 162.

Participants in Phase 2 will then receive the highest tolerated dose that was found in 
Phase 1.
Study Drug Administration
You will take MEK162 tablets by mouth 2 times a day (about 12 hours apart) every 
day with a full cup of water.
There are 4 weeks in each study cycle.
Study Visits
On Day 1 of Cycle 1: 
You will have a physical exam.

Blood (about 4 teaspoons) will be drawn for routine tests and blood sugar 

testing.
On Days 4 and 8 of Cycle 1, blood (about 4 teaspoons) will be drawn for routine 
tests and blood sugar testing.
Sometime during Days 13-27 of each cycle and again on Day 28 of Cycles 2 
and beyond, the study staff will call you and ask about any drugs you may be taking 
and any side effects you may be having.  The calls should last less than 10 minutes 
each time.
On Day 28 of Cycle 1, you will have a bone marrow aspirate and/or biopsy to check 
the status of the disease and for biomarker and cytogenetic testing.  If bone marrow 
cannot be collected, blood (about 1-2 teaspoons) will be drawn for these tests.  
You will have an EKG and either an ECHO or MUGA  scan to check your heart 
function.
On Day 1 of Cycle 2 and beyond:
You will have a physical exam.

Blood (about 4 teaspoons) will be drawn for routine tests and blood sugar 

testing.
Urine will be collected for routine tests.

You will have an eye exam by an eye doctor.

If you can become pregnant, blood (about 1 teaspoon) or urine will be collected 

for a pregnancy test.
On visits when you have blood sugar testing, you should fast for at least 8 hours 
before the blood draw.
On visits when you have urine collected, you will be given containers to collect your 
urine over 24 hours if the doctor thinks it is needed.
If it is more convenient to you, you may be able to have some of your blood draws

done away from MD Anderson.  The study staff will discuss this with you.
Every two or three months during your treatment, you will have an echocardiogram 
(ECHO) or a multigated acquisition (MUGA) scan to check your heart function.
Length of Study
You may continue taking the study drug for as long as the doctor thinks it is in your 
best interest.  You will no longer be able to take the study drug if the disease gets 
worse, if intolerable side effects occur, or if you are unable to follow study directions.
Your participation on the study will be over once you have completed the 
end-of-treatment visit.
End-of-Treatment Visit
After your last dose of study drug:
You will have a physical exam.

Blood (about 2 teaspoons) will be drawn for routine tests

If the doctor thinks it is needed, you will have a bone marrow aspirate and/or

Other Instructions
It is important to tell your doctor about any pre-existing eye problems you have and 
any vision changes you may have while taking the study drug.  Your doctor may 
decide to change or stop your dose of the study drug.  It is important that you do not 
drive a car or work with machinery if you have any vision changes during the study. 
Do not take any new drugs without first checking with your study doctor. This 
includes prescription drugs, over-the-counter drugs, natural or herbal drugs, and 
vitamins.  You will be given a list of drugs that you should not take while on this 
study because they may decrease the effect of the study drug.
3. POSSIBLE RISKS
While on this study, you are at risk for side effects.  These side effects will vary from 
person to person.  The more commonly occurring side effects are listed in this form, 
as are rare but serious side effects.  You should discuss these with the study doctor.  
You may also want to ask about uncommon side effects that have been observed in 
small numbers of patients but are not listed in this form.  Many side effects go away 
shortly after treatment is stopped, but in some cases side effects may be serious, 
long-lasting or permanent, and may even result in hospitalization and/or death.

The drug may cause an increased risk of infection, such as pneumonia. This 
infection may occur anywhere (including the skin). It may become life-threatening. 
Symptoms of infection may include fever, pain, redness, and difficulty breathing.
There is the possibility that these changes could affect the activities of your daily life 
(such as driving a car or operating machinery) It is important to tell your doctor about 
any pre-existing eye problems you have and visual changes that occur while taking 
the study drug as your doctor may decide to change or stop your treatment with the 
study drug.
Other Risks
Blood draws may cause pain, bleeding, and/or bruising.  You may faint and/or 
develop an infection with redness and irritation of the vein at the site where blood is 
drawn.  Frequent blood collection may cause anemia (low red blood cell count), 
which may create a need for blood transfusions.
Bone marrow aspirations/biopsies may cause pain, bruising, bleeding, redness, 
low blood pressure, swelling, and/or infection at the aspiration/biopsy site of the 
collection.  An allergic reaction to the anesthetic may occur.  A scar may form at the 
aspiration/biopsy site.
Genetic research may result in the development of beneficial treatments, devices, 
new drugs, or patentable procedures.  There are no plans to provide you 
compensation from such developments.  The results of any genetic tests may be put 
in your health records. If this information were released, it could be misused.  Such 
misuse could be distressing, and it could cause you or your family members to have 
difficulty obtaining insurance coverage and/or a job. 
Fasting may cause your blood sugar to drop.  You may feel tired, hungry, and/or 
nauseous.  If you have diabetes, it is important to talk to your doctor about managing 
your blood sugar while fasting.
During the eye exams, your pupils will be dilated with eye drops to allow a good 
view of the back of the eye.  This will result in some blurred vision lasting for a few

1. DESCRIPTION OF STUDY
The goal of Phase 2 of this clinical research study is to learn if MEK162 can help to 
control AML in older patients with advanced leukemia.  The safety of this drug will 
also be studied. 
This is an investigational study.  MEK162 is not FDA approved or commercially 
available.  It is currently being used for research purposes only.  The study doctor 
can explain how the study drug is designed to work. 
The study drug will be provided at no cost to you while you are on study.

Up to 57 patients total will take part in both phases of this study.  All will be enrolled 
at MD Anderson.
2. STUDY PROCEDURES
Screening Tests
Signing this consent form does not mean that you will be able to take part in this 
study.  You will have the following screening tests to help the doctor decide if you 
are eligible:
You will have a physical exam.

Blood (about 6 teaspoons) and urine will be collected for routine tests.

You will have a bone marrow aspiration and/or biopsy to check the status of 

the disease and for biomarker, pharmacodynamic (PD), and cytogenetic 
testing.  To collect a bone marrow aspirate and biopsy, an area of the hip or 
other site is numbed with anesthetic, and a small amount of bone marrow and 
bone is withdrawn through a large needle.  Biomarkers are found in the blood 
and tissue and may be related to your reaction to the study drug.  Genetic 
biomarkers will also be studied.  PD testing measures how the level of study 
drug in your body may affect the disease.  Cytogenetic testing looks at how 
genetic changes to cells may affect how the disease may react to the study 
drug.  If you have already had a bone marrow aspirate and/or biopsy recently 
and your doctor thinks repeating it is not needed, leftover bone marrow will be 
used for these tests.  If bone marrow cannot be collected, blood (about 1-2 
teaspoons) will be drawn for these tests.
You will have an electrocardiogram (EKG) and either an echocardiogram 

(ECHO) or a multigated acquisition (MUGA) scan to check your heart 
function. 
You will have an eye exam by an eye doctor.

If you can become pregnant, blood (about 1 teaspoon) or urine will be 

collected for a pregnancy test.  To take part in this study, you must not be 
pregnant.
The study doctor will discuss the screening test results with you.  If the screening 
tests show that you are not eligible to take part in the study, you will not be enrolled.  
Other treatment options will be discussed with you.
Study Groups
If you are found to be eligible to take part in this study, you will be assigned to a 
study group based on when you join this study.  Up to 42 participants will be enrolled 
in Phase 2 of the study.
Participants in Phase 1 were given a dose of MEK162 based on when they joined 
the study. Groups of participants were given different dose levels until the highest 
tolerable dose of MEK162 was found. 
If you are enrolled in Phase 2, you will receive MEK162 at the highest dose that was

tolerated in Phase 1.
Study Drug Administration
You will take MEK162 tablets by mouth 2 times a day (about 12 hours apart) every 
day with a full cup of water.  
There are 4 weeks in each study cycle.
Study Visits
On Day 1 of Cycle 1: 
You will have a physical exam.

Blood (about 4 teaspoons) will be drawn for routine tests and blood sugar 

testing.
On Days 4 and 8 of Cycle 1, blood (about 4 teaspoons) will be drawn for routine 
tests and blood sugar testing.
Sometime during Days 13-27 of each cycle and again on Day 28 of Cycles 2 
and beyond, the study staff will call you and ask about any drugs you may be taking 
and any side effects you may be having.  The calls should last less than 10 minutes 
each time.
On Day 28 of Cycle 1, you will have a bone marrow aspirate and/or biopsy to check 
the status of the disease and for biomarker and cytogenetic testing.  If bone marrow 
cannot be collected, blood (about 1-2 teaspoons) will be drawn for these tests.
You will have an EKG and either an ECHO or MUGA  scan to check your heart 
function. 
On Day 1 of Cycle 2 and beyond:
You will have a physical exam.

Blood (about 4 teaspoons) will be drawn for routine tests and blood sugar 

testing.
Urine will be collected for routine tests.

You will have an eye exam by an eye doctor.

If you can become pregnant, blood (about 1 teaspoon) or urine will be collected 

for a pregnancy test.
On visits when you have blood sugar testing, you should fast for at least 8 hours 
before the blood draw.
On visits when you have urine collected, you will be given containers to collect your 
urine over 24 hours if the doctor thinks it is needed.
If it is more convenient to you, you may be able to have some of your blood draws 
done away from MD Anderson.  The study staff will discuss this with you.

Every two or three months during your treatment, you will have an echocardiogram 
(ECHO) or a multigated acquisition (MUGA) scan to check your heart function.
Length of Study
You may continue taking the study drug for as long as the doctor thinks it is in your 
best interest.  You will no longer be able to take the study drug if the disease gets 
worse, if intolerable side effects occur, or if you are unable to follow study directions.
Your participation on the study will be over once you have completed the 
end-of-treatment visit.
End-of-Treatment Visit
After your last dose of study drug:
You will have a physical exam.

Blood (about 2 teaspoons) will be drawn for routine tests

If the doctor thinks it is needed, you will have a bone marrow aspirate and/or 

biopsy to check the status of the disease and for biomarker, PD, and/or 
cytogenetic testing.  If you have already had a bone marrow aspirate and/or 
biopsy recently and your doctor thinks repeating it is not needed, leftover bone 
marrow will be used for these tests.  If bone marrow cannot be collected, blood 
(about 1-2 teaspoons) will be drawn for these tests.
You will have an EKG.

Other Instructions
It is important to tell your doctor about any pre-existing eye problems you have and 
any vision changes you may have while taking the study drug.  Your doctor may 
decide to change or stop your dose of the study drug.  It is important that you do not 
drive a car or work with machinery if you have any vision changes during the study. 
Do not take any new drugs without first checking with your study doctor. This 
includes prescription drugs, over-the-counter drugs, natural or herbal drugs, and 
vitamins.  You will be given a list of drugs that you should not take while on this 
study because they may decrease the effect of the study drug.
3. POSSIBLE RISKS
While on this study, you are at risk for side effects.  These side effects will vary from 
person to person.  The more commonly occurring side effects are listed in this form, 
as are rare but serious side effects.  You should discuss these with the study doctor.  
You may also want to ask about uncommon side effects that have been observed in 
small numbers of patients but are not listed in this form.  Many side effects go away 
shortly after treatment is stopped, but in some cases side effects may be serious, 
long-lasting or permanent, and may even result in hospitalization and/or death.

(possible organ damage 
such as stroke and/or 
heart attack)
dehydration

nail disorders

(possibly leaking 
contents into the 
abdomen)
increased risk of 

bleeding (possible in 
the nose, stomach, 
intestines and/or brain)
liver failure

muscle spasms

breakdown products of 


The drug may cause an increased risk of infection, such as pneumonia. This 
infection may occur anywhere (including the skin). It may become life-threatening. 
Symptoms of infection may include fever, pain, redness, and difficulty breathing.
There is the possibility that these changes could affect the activities of your daily life 
(such as driving a car or operating machinery) It is important to tell your doctor about 
any pre-existing eye problems you have and visual changes that occur while taking 
the study drug as your doctor may decide to change or stop your treatment with the 
study drug.
Other Risks
Blood draws may cause pain, bleeding, and/or bruising.  You may faint and/or 
develop an infection with redness and irritation of the vein at the site where blood is 
drawn.  Frequent blood collection may cause anemia (low red blood cell count), 
which may create a need for blood transfusions.
Bone marrow aspirations/biopsies may cause pain, bruising, bleeding, redness, 
low blood pressure, swelling, and/or infection at the aspiration/biopsy site of the 
collection.  An allergic reaction to the anesthetic may occur.  A scar may form at the 
aspiration/biopsy site.
Genetic research may result in the development of beneficial treatments, devices, 
new drugs, or patentable procedures.  There are no plans to provide you 
compensation from such developments.  The results of any genetic tests may be put 
in your health records. If this information were released, it could be misused.  Such 
misuse could be distressing, and it could cause you or your family members to have 
difficulty obtaining insurance coverage and/or a job. 
Fasting may cause your blood sugar to drop.  You may feel tired, hungry, and/or 
nauseous.  If you have diabetes, it is important to talk to your doctor about managing 
your blood sugar while fasting.
During the eye exams, your pupils will be dilated with eye drops to allow a good 
view of the back of the eye.  This will result in some blurred vision lasting for a few 
hours.  You will not be able to drive during this time.
