Study 
Design: 
 
Phase 1: Safety Run In 
 
This portion of the study will assess whether a dose of trametinib 1.5mg by mouth once 
daily and erlotinib 75mg by mouth once daily is a tolerable and safe dose. Six patients 
will be enrolled at this dose level and assessed for dose limiting toxicities (DLTs) for 1 
full cycle (28 days). Toxicity will be graded according to NCI CTCAE version 4.0. If more 
than one patient develops a DLT, we will move on to the phase 2 portion of the study 
and the dose level -1 will be used. If no <1 DLT is detected, we will move on to the 
phase 2 portion of the study at dose level 0.

Phase 2: 
 
Once the phase 1 run-in portion of the study has been completed, patients will be 
enrolled in the phase 2 portion of the single-arm, two-stage, open-label study of 
trametinib and erlotinib in the treatment of patients with EGFR-mutant lung cancers with 
acquired resistance to erlotinib.  After screening and registration, patients will be treated 
with the combination of trametinib and erlotinib. Response to therapy will be assessed 
by interval imaging every 8 weeks (every 2 cycles) with CT scan of the chest and 
imaging of any other target lesion with response evaluated by RECIST 1.1. A maximum 
of 24 patients will be enrolled during this portion of the study. 
Correlative studies: 
 
Biopsies will be required within 30 days of start of study treatment and at the time of 
progression. At prespecified time points and after additional informed consent, patients 
will have image-guided core needle biopsies with 3-4 cores obtained. At least 2 cores 
will be immediately frozen in liquid nitrogen and sent to Dr. Rudin’s lab. The remaining 
cores will be fixed in formalin and sent to Surgical Pathology. We will use our genomics 
core facility for all DNA and RNA extraction and analysis. IHC will be performed to look 
at expression of specific proteins of interest including:  BIM, TGFB2, vimentin, e- 
cadherin, n-cadherin and neurofibromin. Transcriptome sequencing (RNA-Seq) will be 
utilized to look at changes in gene expression at various time points of treatment and to 
identify potential biomarkers of response to combination therapy.  IMPACT,  our next- 
generation sequencing based mutation platform that assesses for genetic alterations in 
340 cancer-related genes, will be used for molecular analysis.

BACKGROUND AND RATIONALE 
 
3.1 EGFR-mutant lung adenocarcinoma and acquired resistance to EGFR tyrosine Kinase 
Inhibitors 
Twenty percent of patients with metastatic lung adenocarcinoma have somatic activating 
mutations in the epidermal growth factor receptor (EGFR). Patients with these oncogene-addicted 
lung adenocarcinomas have a 70% response rate to EGFR-TKI therapy (erlotinib, afatinib, or 
gefitinib) and a median progression-free survival of 12 months.4 All of these patients will develop 
resistance to EGFR TKI therapy and clinical progression. A mechanism of resistance can be 
identified 82% of the time, with acquisition of EGFR T790M seen most frequently.5  There are 
several EGFR T790M targeting EGFR inhibitors 
currently in clinical development. CO-1686, which 
targets mutant EGFR including T790M, has a reported 
overall response rate of 58% in 40 patients with centrally 
confirmed EGFR T790M tumors.6 AZD9291, another 
mutant specific EGFR TKI, has a reported response rate 
of 64% in 107 patients with EGFR T790M mutant 
tumors.7 At this time however, there are currently no 
approved drugs available for patients with acquired 
resistance to EGFR TKIs. Therapeutic options are 
especially limited for patients without acquired EGFR 
T790M present in their tumors.

Role of BIM and apoptosis 
 
Expression of the apoptotic protein BIM is required for 
apoptosis triggered by EGFR tyrosine kinase inhibitors 
(TKIs).2,8-10  (Figure 1) Treatment with EGFR TKIs 
induces rapid and sustained increases in the level of 
BIM, and knockdown of BIM nearly eliminates EGFR 
TKI-induced cell killing in EGFR-mutant cell lines.8 
Levels of pre- treatment (and post-treatment) BIM 
predict response to EGFR TKI therapy with an 
association of both response rate and progression-free 
survival on EGFR TKI with BIM expression. 2  Similar 
results were seen when analyzing BIM mRNA 
expression of patients with EGFR-mutant lung cancers 
treated in the EURTAC trial.11  Progression-free survival 
on erlotinib and overall survival were shorter in those with 
low BIM expression.11 
The importance of BIM was again demonstrated in patients with a BIM deletion polymorphism that 
results in an isoform of BIM without the crucial BH3 domain that is required for BIM’s apoptotic 
function.1    The presence of this polymorphism was predictive of a shorter progression free  
survival with erlotinib re-emphasizing the importance of BIM expression to response to TKI 
therapy.1  (Figure 2) 
Inhibition of the MEK/ERK pathway is critical for BIM upregulation required for TKI-induced 
apoptosis.  MEK inhibition is sufficient to induce rapid BIM induction by preventing 
dephosphorylation resulting in BIM accumulation.10  In EGFR T790M containing cell lines, there is 
increased phosphorylated ERK in the presence of an EGFR TKI that was attenuated with the 
addition of a MEK inhibitor.9  In sensitive EGFR mutant cell lines, the addition of a MEK inhibitor to 
an EGFR inhibitor may not be additive, but in the resistance setting there is more limited BIM 
induction and the additive effect of a MEK inhibitor may be more apparent. Song and colleagues 
evaluated dual MEK and EGFR inhibition which resulted in apoptosis in EGFR resistant, EGFR 
T790M containing cell lines (H1975) with decreased phospho-ERK and increased BIM 
expression.12    Induction of BIM through MEK inhibition has the potential to re-sensitize patients to 
EGFR TKI irrespective of EGFR T790M status making this a potential treatment strategy in all 
patients with acquired resistance to EGFR TKI therapy. 
Additional support for MEK inhibition in EGFR-mutant lung cancers 
 
In addition to acquisition of EGFR T790M, there are multiple other mechanisms of acquired 
resistance to EGFR TKI therapy. Histologic transformation including epithelial-mesenchymal 
transition (EMT) is a mechanism of resistance identified in tumor samples in patients treated with 
EGFR TKI.13    ERK/MAPK pathway activation is required for TGF-B2 induced EMT.14  Inhibition of 
MEK was able to prevent EMT and augment sensitivity to gefitinib in cell lines resistant to EGFR 
TKI therapy.15

Another mechanism of resistance to EGFR 
TKI identified is decreased expression of 
neurofibromin that results in incomplete 
inhibition of RAS/ERK signaling in the 
presence of erlotinib.3  Low NF1 expression 
was associated with both primary and 
secondary resistance to EGFR TKIs. 
Treatment of neurofibromin deficient lung 
cancers with a trametinib and erlotinib 
restored sensitivity to erlotinib. (Figure 3). 
Preliminary data and Rationale for Dose 
Selection: 
Trametinib is approved for the treatment of 
BRAF-mutant melanomas at a dose of 2mg 
orally daily. A phase 1 study of trametinib 
and erlotinib was conducted in patients with 
solid tumors (NCT01192165).   Twenty-two 
patients were treated and 3 dose-limiting 
toxicities were seen: 1 DLT of diarrhea at 
the dose of trametinib 1mg with erlotinib 100mg and 2 DLTs of diarrhea and mucositis with 
trametinib 1.5mg with erlotinib 100mg. Most common side effects (>30% of all patients), any 
grade, were diarrhea, rash, fatigue, nausea, vomiting, anorexia, hypokalemia and anemia. The 
maximum tolerated dose level of the combination was determined to be trametinib 1mg daily and 
erlotinib 100mg daily. No partial or complete responses were seen in this unselected population. 
Prophylactic antidiarrheals were not utilized on protocol. 
We hypothesize that effective MEK inhibition with trametinib will circumvent acquired resistance to 
erlotinib therapy. We would therefore like to first conduct a phase 1 safety run in with a higher 
dose of MEK inhibitor (trametinib 1.5mg once daily) with a reduced dose of erlotinib at 75mg once 
daily. This dose had not been tested during the previous phase 1 study described above. It is our 
hypothesis that a lower dose (75mg) of erlotinib would allow us to maximize the dose of trametinib 
given. We will also utilize prophylactic anti-diarrheal medications to minimize toxicities. Six  
patients will be accrued to this portion of the study. If zero to one patient experiences a toxicity 
with these doses, we will move to the phase 2 portion of the study. If two or more patients develop 
a DLT at this higher dose of trametinib, we will use trametinib 1mg daily with erlotinib 100mg daily 
during the phase 2 portion of the study.

will move on to the phase 2 portion of the study and the dose level -1 will be used. Dose level -1 
was already deemed safe in a previous phase 1 study (NCT01192165). If < 1 DLT is detected, we 
will move on to the phase 2 portion of the study at dose level 0. Two to six patients will be enrolled 
in the phase 1 portion.

Phase 2: 
 
Once the run-in phase 1 portion of the study has been completed, patients will be enrolled in the 
phase 2 portion of the single-arm, two-stage, open-label study of trametinib and erlotinib in the 
treatment of patients with EGFR-mutant lung cancers with acquired resistance to erlotinib.  After 
screening and registration, patients will be treated with the combination of trametinib and erlotinib. 
Response to therapy will be assessed by interval imaging every 8 weeks (every 2 cycles) with CT 
scan of the chest and imaging of any other target lesion with response evaluated by RECIST 1.1. 
A maximum of 24 patients will be enrolled in the phase 2 study. Dosing for the phase 2 portion of 
the study will depend on the results from the run In Phase 1 Portion. If 0-1 DLTs occur, and dose 
level 0 is used in the phase 2 portion, the patients treated in the phase 1 portion at dose level 0 
will be included in the phase 2 portion.

TREATMENT/INTERVENTION PLAN 
 
Erlotinib will be commercially obtained. Investigators should reference the current approved 
prescribing information. A pill diary will be used to track adherence. Erlotinib is administered daily, 
at approximately the same time of day every day. Erlotinib should be taken on an empty stomach 
(at least 1 hour before, or 2 hours after the ingestion of food). If vomiting occurs during the course 
of treatment, patients should not take an additional dose of erlotinib that day. The patient should 
resume treatment with the next scheduled dose. If more than 12 hours have elapsed, that day’s 
dose should be omitted, and the patients should continue treatment with the next scheduled dose. 
A pill diary will be used to record adherence. 
9.1.2 Therapeutic Agent-Trametinib 
 
Trametinib will be supplied for the purposes of this trial by Novartis. Trametinib is given once daily 
and can be taken with or without food at approximately the same time of the day each day. A pill 
diary will be used to record adherence.

9.2 Treatment Arms 
 
All patients will receive trametinib and erlotinib in this single-arm study. 
 
9.3 Study design 
 
Phase 1 (safety run-in): This portion of the study will assess whether a dose of trametinib 1.5mg 
by mouth once daily and erlotinib 75mg by mouth once daily is a safe dose. Six patients will need 
to be enrolled at this dose level and assessed for dose limiting toxicities (DLTs) for 1 full cycle (28 
days). Toxicity will be graded according to NCI CTCAE version 4.0. If more than one patient 
develops a DLT, we will move on to the phase 2 portion of the study and the dose level -1 will be 
used. Dose level -1 of trametinib 1mg daily and erlotinib 100mg daily was already established to 
be safe and tolerable in a previous phase 1 study. If <1 DLTs are detected, we will move on to the 
phase 2 portion of the study at dose level 0.

Phase 2: All patients will receive erlotinib and trametinib at the dose level defined during the 
phase 1 portion of the study. Patients will be monitored for response by CT every 2 cycles (8 
weeks). The first 8 week response will be considered the primary objective outcome for this 
portion of the study. The schedule of evaluations and interventions is described in Section 10.0. 
9.4 Dose Limiting Toxicities: 
 
The NCI Common Terminology Criteria for Adverse Events Version 4.0 (NCI CTCAE) will be used 
to grade toxicities during the trial. Dose limiting toxicities (DLTs) are defined as any of the  
following events occurring during the first cycles of treatment (i.e. 4 weeks) that are, in the opinion 
of the treatment physician, possibly, probably, or definitely related to the investigational regimen: 
• 
Death related to the investigational regimen 
• 
Hematologic toxicities including: 
o Grade=4 neutropenia lasting >5 days 
o Grade=4 thrombocytopenia (<25,000/mm3) 
o Grade≥ thrombocytopenia with evidence of clinically significant bleeding 
o Grade=4 anemia 
• 
Non-hematologic toxicities include: 
o Grade ≥ 3 AST, ALT, alkaline phosphatase or total bilirubin 
o Grade  ≥ 3 diarrhea, nausea, vomiting that lasts >72 hours despite optimal 
maximum supportive care 
o Grade 4 diarrhea, nausea, vomiting 
o Any other non-hematologic grade  ≥3  major organ toxicity 
o central serous retinopathy or retinal vein occlusion 
9.5 Correlative Studies: Biopsies will be required prior to start of study treatment and at the time 
of progression. At prespecified time points, and after additional informed consent, patients will

have image-guided core needle biopsies with 3-4 cores obtained. At least 2 cores will be 
immediately frozen in liquid nitrogen and sent to Dr. Rudin’s lab. 
 
 
The remaining cores will be fixed in formalin and sent to Surgical Pathology. Blood will also be 
used for IMPACT  testing for next-generation sequencing based testing if not obtained previously. 
DNA/RNA will be extracted from one flash-frozen core using an AllPrep® DNA/RNA mini kit 
(Qiagen). RNA quality will be assessed at the MSKCC integrative genomics (iGO) core facility 
using an Agilent Bioanalyzer 2100 platform. We will perform RNA-seq on all patients with 
sufficient tissue from the phase 2 cohort, to quantify changes in gene expression at various time 
points of treatment and to identify potential biomarkers of response to combination therapy. 
Extracted RNA (5ug) will be submitted to Genewiz for single-end 75bp reads on a HiSeq 2500 
instrument. RNA samples that are limiting in quality/amount will be amplified using the Ovation® 
RNA-seq System V2 kit (NuGen) and submitted for RNA-seq as cDNA. We expect RNA yields 
from core biopsies to be limiting, thus we will not perform rRNA depletion prior to submission of 
samples. Analysis of RNA-seq data will be performed at the MSKCC Bioinformatics core facility. 
Remaining RNA will be frozen at -80C for validation of genes of interest highlight by RNA-seq 
data. Validation will be performed using either RT-PCR or through the construction of a custom 
nanostring nCounter panel that includes genes of interest. One fixed core will be used for 
immunohistochemistry to determine protein expression for transcripts of interest, including:  BIM, 
cleaved caspase 3, TGFB2, vimentin, e-cadherin, n-cadherin and neurofibromin. MSK-IMPACT, 
our next-generation sequencing based mutation platform that assesses for genetic alterations in 
340 cancer-related genes will be used for molecular analysis.

EVALUATION DURING TREATMENT/INTERVENTION 
 
Tables 10.1 outlines the schedule of assessments applied to patients. If the subject is unable to 
have a study assessment taken within the defined time window due to an event outside of his or 
her control (e.g. clinic closure, personal emergency, inclement weather, vacation) the assessment 
should be performed as close as possible to the required schedule. More frequent assessments 
should be obtained if clinically indicated. Subjects will return to the study site within 30 days after 
their last dose of trametinib and erlotinib to complete end of study assessments outlined below. 
Additional follow up will occur for subjects with AEs related to study treatment that are ongoing at 
the time of this visit and for subjects with SAEs related to study treatment that occur after the time 
of this visit.

biomicroscopy of the anterior segment (with special attention to inflammation) and the posterior segment, 
and indirect funduscopic  examination with special attention to possible retinal abnormalities .  Exams are 
required  at screening,  month 1 +/- 2 week, and month 6 +/- 4 weeks. Additional ophthalmic exams will be 
performed  if symptomatically warranted. 
3CMP includes glucose, blood urea nitrogen,  creatinine, sodium, potassium, chloride,  bicarbonate,  calcium, 
total protein, albumin, serum bilirubin, alkaline phosphatase,  ALT, AST 
4A single 12 lead ECG should be performed  at screening and day 1 of every  cycle +/- 2 weeks. 
5Echocardiogram  should be performed  at screening and every  three cycles +/- 2 weeks 
6Response to therapy  will be assessed by interval  imaging studies every  2 cycles (8 weeks)+/- 2 weeks with 
response evaluated  using RECIST version  1.1. Radiologic  imaging will include a CT chest +/ - 
abdomen/pelvis  depending  on sties of disease with or without contrast.  If an appropriate  imaging study is 
performed  early for any reason (i.e. hospitalization), it can be used for disease assessment. CT scans  
should be completed if the patient comes off study for any reason other than progression.  If a CT scan was 
completed within the last 8 weeks, it will not need to be repeated.

TOXICITIES/SIDE EFFECTS 
 
Adverse events occurring in patients treated with trametinib and erlotinib may be 1) overlapping 
toxicities seen in both agents (i.e. rash, diarrhea, and pneumonitis); 2) toxicities typically 
associated with trametinib (i.e. visual disturbance, QTc prolongations) or 3) toxicities typically 
associated with erlotinib. However, toxicities with individual agents may be potentiated in the 
combination or unanticipated AEs may occur.  The dose modifications may involve one or both 
agents, and should be based on the nature, severity, and attributions of the AEs. General 
guidelines are provided below. For safety and adverse event reporting, see Section 17.0. 
 
While AEs may be thought to be related to individual agents for purposes of dose modifications, 
all toxicities will be considered related to combination therapy for description of AE profile.

Trametinib  should be discontinued if treatment delay is >21 days due to toxicities.  If the investigator 
concludes that continued trametinib will benefit  a patient, the study PI and GSK medical monitor may be 
consulted for the possibility of resuming trametinib, provided  that toxicities have  resolved  to grade ≤1. 
 
11.3 
Specific Dose Modifications 
 
11.3.1 Rash 
 
Rash is a frequent AE observed in patients receiving trametinib and erlotinib (package insert). 
Recommendations for supportive care and guidelines for dose modifications for rash are based 
on experience with other MEK inhibitors and EGFR inhibitors.16,17  Patients should be informed  
that skin toxicity is expected during treatment with erlotinib and trametinib. Skin toxicity can take 
the form of dry skin, rash, acneiform eruption, and hair/nail changes. Prophylactic treatment of the 
skin with the recommendations below may prevent or reduce skin toxicity. 
 
Patients with significant skin toxicity will be referred to dermatology for management. 
Recommended treatments may include topical therapy such as hydrocortisone cream or 
clindamycin gel. If needed, oral minocycline or oral doxycycline may be combined with topical 
therapy. For more severe cases, oral corticosteroids may be administered. Patients who fail to 
respond to these measures may have erlotinib and or trametinib interrupted, dose reduced, or 
discontinued.

Recommendations 
Prevention/Prophylaxisa 
• Avoid unnecessary exposure to sunlight. 
• Apply broad-spectrum sunscreen (containing titanium dioxide or 
zinc oxide) with a skin protection factor (SPF) ≥15 at least twice 
daily. 
• Use thick, alcohol-free  emollient cream (e.g., glycerine and 
cetomacrogol cream) on dry areas of the body at least twice daily. 
• Topical steroids and antibiotics should be applied at least twice 
daily, starting on Day 1 of study treatment, to affected  body areas 
such as face, chest, and upper back. 
• Consider mild-strength topical steroid (hydrocortisone  1% cream) or 
topical antibiotic (e.g., clindamycin) or oral antibiotics (e.g., 
doxycycline 100 mg BID, minocycline 100 mg BID). 
Symptomatic  Careb 
• Pruritic lesions:  Cool compresses and oral antihistamine therapies. 
• Fissuring lesions:  Monsel’s solution, silver nitrate, or zinc oxide 
cream. 
• Desquamation:   Thick emollients and mild soap. 
• Paronychia:   Antiseptic bath, local potent corticosteroids in addition 
to antibiotics; if no improvement,  consult dermatologist  or surgeon. 
• Infected lesions:  Appropriate bacterial/fungal   culture-driven 
systemic or topical antibiotics. 
a Rash prophylaxis  is recommended  for the first 6 weeks of study treatment. 
b Patients who develop  rash/skin toxicities should be seen by a qualified  dermatologist and should 
receive  evaluation  for  symptomatic/supportive  care management.

11.3.6 Visual Changes 
 
Episodes of visual changes have been observed in patients receiving trametinib.  The causal 
relationship between a change in vision and the study treatment should be carefully explored and 
an ophthalmologist should be consulted.  Patients are required to have a standard ophthalmic 
exam performed by an ophthalmologist at baseline and as clinically warranted.  The exam will 
include indirect funduscopic examination, visual acuity (corrected), visual field examination, 
tonometry, and direct funduscopy.  Special attention should be given to retinal (e.g., CSR) or 
retinal vein abnormalities (e.g., RVO).

The same method of assessment (i.e. CT or MRI) and the same technique (i.e. with or without 
contrast) should be used to characterize each identified and reported lesion at baseline and every 
two cycles (+/- 1 week). A designated radiologist at MSKCC will interpret the study CTs or MRIs 
according to RECIST 1.1 criteria. The same radiologist/physician should perform the evaluation 
for the entire duration of the study. 
Tumor response will be assessed using RECIST 1.1. Confirmation of response will not need to be 
required. A CT scan of the chest +/- abdomen/pelvis will be performed to demonstrate all known 
areas of measurable disease. The baseline study will occur no more than 4 weeks prior to first 
study drug administration. A CT scan with contrast will be the preferred method and modality of 
imaging. A CT scan without contrast or MRI can be used in patients with contraindications to 
radiographic contrast media used in CT scans. All patients must have at least one measurable 
disease lesion by CT or MRI. 
All measurable lesions, up to a maximum of 5 lesions total, representative of all involved organs 
should be identified as target lesions and recorded and measured at baseline. Target lesions 
should be selected on the basis of their size, should be representative of all involved organs, and 
should lend themselves to reproducible repeat measurements. All other lesions (or sites of 
disease) should be identified as non-target lesions and should also be recorded at baseline. 
Definitions of response in target and non-target lesions are described in table 12.1. Table 12.2 
provides overall responses for all possible combination of tumor responses in target and non- 
target lesions. 
 
Table 12.1 Evaluations of Target Lesions 
Complete response (CR): 
Disappearance of all target lesions 
Partial Response (PR): 
At least a 30% decrease in the sumo of the 
diameters of the target lesions 
Progressive Disease (PD): 
At least a 20% increase in the sum of the 
diameters of the target lesions or the 
appearance of one ore more new lesions 
Stable Disease (SD): 
Neither sufficient shrinkage or qualify to PR 
nor sufficient increase to qualify for PD 
 
Table 12.2 Evaluations of Non-Target Lesions 
Complete response (CR): 
Disappearance of all non-target lesions

BIOSTATISTICS 
Phase 1: Safety Run In 
Primary Objective: To determine the safety and tolerability of the combination of erlotinib 75mg 
by mouth once daily with trametinib 1.5mg by mouth once daily in patients with EGFR mutant lung 
cancer and acquired resistance to EGFR tyrosine kinase inhibitors. 
Endpoints: Identify any dose limiting toxicities of the combination. A dose limiting toxicity is a binary

outcome where a patient either experiences a DLT or not. DLT is defined as any of the toxicities 
described in Section 9 that occurs within one cycle after initiation of treatment with erlotinib and 
trametinib. 
Method: Up to six patients will be enrolled at dose level 0 (trametinib 1.5mg by mouth once daily 
and erlotinib 75mg by mouth once daily) and assessed for dose limiting toxicities (DLTs) for 1 full 
cycle (28 days). Toxicity will be graded according to NCI CTCAE version 4.0. If more than one 
patient develops a DLT, we will move on to the phase 2 portion of the study and the dose level -1 
will be used. If <1 DLTs are detected, we will move on to the phase 2 portion of the study at dose 
level 0. 
If 0-1 DLTs occur, and dose level 0 is used in the phase 2, the  patients accrued during the phase 
1 portion of the study will be followed for response assessment and included in the phase 2 portion 
of the study. Given an expected accrual rate of 2 patients per month, the accrual to the phase 1 
portion of the study will be completed in about 3 months. Two to six patients will be enrolled in the 
phase 1 portion of the study.

Phase 2: 
 
Primary Objective:To determine the ORR of the combination of erlotinib and trametinib in patients 
with EGFR mutant lung cancer and acquired resistance to EGFR tyrosine kinase inhibitors 
 
Secondary Objective: To determine the progression free survival and overall survival and further 
assess the toxicity of trametinib and erlotinib 
Methods: A Simon optimal two-stage trial design will be utilized to assess the primary endpoint of 
response rate (RECIST 1.1 CR+PR). This study will test the null hypothesis of 5% response rate 
against the alternative hypothesis of 25% response rate for patients with acquired resistance. A 
null hypothesis of 5% was chosen because all eligible patients have demonstrated progression and 
lack of response to erlotinib. The most effective treatment for both EGFR T790M positive and 
negative patients is afatinib and cetuximab which has a response rate of 29% but results in 
significant adverse events18. Subsequently, an alternative hypothesis of 25% was chosen for this 
study. The design chosen has a 10% type I error (falsely accepting a non-promising therapy), 10% 
type II error (falsely rejecting a promising therapy), for 90% power.  In the first stage of this design, 
9 patients will be treated. If 0 responses are seen in the first 9 patients, the trial will be stopped and 
declared negative. If at least 1 response is observed, than an additional 15 patients will be accrued 
to the second stage. At the end of the study, if 3 or more patients have a response out of a total of 
24 patients enrolled, the combination of trametinib and erlotinib will be considered worthy of further 
investigation. Overall survival and time to progression will be estimated using the Kaplan-Meier 
method, with the follow-up starting at the initiation of therapy. Patients will be censored at the time 
of the last on-study evaluation if they do not experience the event of interest. Safety and tolerability 
will be summarized using descriptive statistics. The toxicities and the adverse events will be 
assessed for each patient according to the NCI CTCAE version 4.0 criteria. All correlative aims are 
exploratory and will be hypothesis-generating only.

Given an expected accrual rate of 2 patients per month, the accrual to the phase 2 portion of the 
study will be completed in about 6-12 months. 
Correlatives: For the correlative studies, the analysis is primarily exploratory and hypothesis 
generating. Correlative studies will be performed on all patients participating in both the phase 1 
and 2 portions of this clinical trial. 
 
 
Method: EGFR T790M status will be determined for the biopsy samples obtained at the time of 
acquired resistance to EGFR TKI monotherapy. The portion of patients with T790M mutation will 
be calculated along with the exact 95% confidence interval. The expression of proteins such as 
BIM, TGFB2, vimentin, e-cadherin, n-cadherin, and neurofibromin will be quantified using 
immunohistochemical (IHC) staining in the biopsy tissue obtained and reported as a proportion of 
patients with each IHC score. Results will be summarized at each time point using descriptive 
statistics (mean +/- std). Graphical methods will be used to evaluate the way protein expression 
changes during the course of treatment.

16.2 
Quality Assurance 
Weekly meetings will occur to monitor patient accrual and completeness of registration data. 
Routine data quality reports will be generated to assess missing data and inconsistencies. 
Accrual rates and extent and accuracy of evaluations and follow up will be monitored 
periodically throughout the study period and potential problem will be brought to the 
attention of the study team for discussion and action. Random sample data quality and 
protocol compliance audits will be conducted by the study team, at a minimum of two times 
a year, and more frequently if indicated.

Data and Safety Monitoring 
 
The Data and Safety Monitoring (DSM) Plans at Memorial Sloan-Kettering Cancer Center 
were approved by the National Cancer Institute in September 2001. The plans address the 
new policies set forth by the NCI in the document entitled “Policy of the National Cancer 
Institute for Data and Safety Monitoring of Clinical Trials” which can be found at:  
http://cancertrials.nci.nih.gov/researchers/dsm/index.html. The  DSM  Plans  at  MSKCC 
were established and are monitored by the Office of Clinical Research. The MSKCC Data 
and

Monitoring 
Plans 
can

on 
the 
MSKCC 
Intranet 
at:  
http://mskweb2.mskcc.org/irb/index.htm 
 
There are several different mechanisms bywhich clinical trials are monitored for data, safety 
and quality. There are institutional processes in place for quality assurance (e.g., protocol 
monitoring, compliance and data verification audits, therapeutic response, and staff 
education on clinical research QA) and departmental procedures for quality control, plus 
there are two institutional committees that are responsible for monitoring the activities of our 
clinical trials programs. The committees: Data and Safety Monitoring Committee (DSMC) 
for Phase I and II clinical trials, and the Data and Safety Monitoring Board (DSMB) for Phase 
III clinical trials, report to the Center’s Research Council and Institutional Review Board. 
 
During the protocol development and review process, each protocol will be assessed for its 
level of risk and degree of monitoring required. Every type of protocol (e.g., NIH sponsored, 
in-house sponsored, industrial sponsored, NCI cooperative group, etc.) will be addressed 
and the monitoring procedures will be established at the time of protocol activation.

17.1 
PROTECTION OF HUMAN SUBJECTS 
 
Prior to the enrollment of each patient, the risks, benefits, and objectives of the study will be 
reviewed with the participant, including a discussion of the possible toxicities and side  
effects. Alternative,  non-protocol, treatment options will be discussed with the patient. It will 
be reviewed that participation in this clinical trial is voluntary and that the patient may 
withdraw consent at any time. The study is designed with careful safety monitoring for toxicity 
including physician visits. Specific guidelines for symptom management are in place to 
protect the study participants. 
Human Subjects Involvement and Characteristics: All patients at MSKCC who meet the 
inclusion criteria will be eligible to enroll. Patients eligible will be 18 years of age or older with 
a KPS of 70% or greater. Both men and women and members of all ethnic groups will be 
eligible for this trial. Pregnant and breast feeding women are excluded from this study. This 
protocol does not include children because the number of children is expected to be limited 
for the patient population expected to be accrued onto this study. Also the majority of  
children are already accessed by a nationwide pediatric cancer research network. This 
statement is based on exclusion 4b of the NIH policy and guidelines on the Inclusion of 
Children as Participants in Research Involving Human Subjects. 
Consent process: All patients at MSKCC who meet the inclusion criteria will be eligible. 
Participation in the trial is voluntary. All patients will be required to sign a statement of 
informed consent, which must conform to IRB guidelines. The informed consent procedure is 
described in Section 18.0. 
Possible Toxicities: There are risks associated with treatment as described in Section 11.0. 
 
Benefits: The combination of trametinib and erlotinib has the potential to be effective and 
induce tumor response in patients with EGFR mutant lung cancer and acquired resistance to 
erlotinib. 
Costs: Patients will be charged (insurance billed) for physician visits, erlotinib, routine 
laboratory tests, and radiologic studies required for monitoring their condition. The patients 
will not be billed for the study drug, trametinib. The research studies will be covered with 
separate research funding and no charges associated with research will be billed to the 
patient. Repeat biopsy on progression of disease on study will not be charged to the patient. 
Alternatives: The alternative to this trial would be treatment with chemotherapy with or 
without continuation of erlotinib or participation in an alternative clinical trial. 
Confidentiality: Every effort will be made to maintain patient confidentiality. Research and 
hospital records are confidential. Patients’ names and any other identifying information will 
not be used in reports or publications resulting from this study. Other authorized agencies 
and appropriate internal personnel (e.g. qualified monitors from MSKCC) and external 
personnel (e.g. qualified monitors from Novartis(the manufacturer of trametinib), its 
authorized agents, the FDA, and/or other governmental agencies) may review patient 
records as required.

Patient Safety: Patients are monitored by physicians and oncology nurses who are very 
familiar with clinical trials. In the case of an adverse reaction, immediate medical attention is 
available. In the evenings and weekends, we have a 24 hour urgent care facility for 
outpatients. The PI or co-PI will also be available at all times to organize any necessary 
intervention. 
Monitoring of data to ensure safety: The study is to be monitored by the institutional IRB. 
This incorporates an independent data and safety monitoring board established by 
arrangement with the National Cancer Institute. The analysis of safety will include all 
patients. Adverse events, including all toxic effects of treatment, will be tabulated individually 
and summarized by severity and causality. 
17.2 
Privacy 
 
MSK’s Privacy Office may allow the use and disclosure of protected health information 
pursuant to a completed and signed Research Authorization form. The use and disclosure of 
protected health information will be limited to the individuals described in the Research 
Authorization form. A Research Authorization form must be completed by the Principal 
Investigator and approved by the IRB and Privacy Board (IRB/PB). 
 
 
An adverse event is considered serious if it results in ANY of the following outcomes: 
• 
Death 
• 
A life-threatening adverse event 
• 
An adverse event that results in 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 (IME) that may not result in death, be life threatening, or require 
hospitalization may be considered serious when, based upon medical judgment, they may 
jeopardize the patient or participant and may require medical or surgical intervention to prevent one 
of the outcomes listed in this definition 
 
Note: Hospital admission for a planned procedure/disease treatment is not considered an SAE. 
 
SAE reporting is required as soon as the participant starts investigational treatment/intervention. 
SAE reporting is required for 30-days after the participant’s last investigational 
treatment/intervention. Any event that occur after the 30-day period that is unexpected and at least 
possibly related to protocol treatment must be reported. 
 
Please note: Any SAE that occurs prior to the start of investigational treatment/intervention and is 
related to a screening test or procedure (i.e., a screening biopsy) must be reported. 
All SAEs must be submitted in PIMS. If an SAE requires submission to the HRPP office per IRB 
SOP RR-408 ‘Reporting of Serious Adverse Events’, the SAE report must be submitted within 5 
calendar days of the event. All other SAEs must be submitted within 30 calendar days of the event. 
 
The report should contain the following information: 
• The date the adverse event occurred

• The adverse event 
• The grade of the event 
• Relationship of the adverse event to the treatment(s) 
• If the AE was expected 
• Detailed text that includes the following 
o An explanation of how the AE was handled 
o A description of the participant’s condition 
o Indication if the participant remains on the study 
• If an amendment will need to be made to the protocol and/or consent form 
• If the SAE is an Unanticipated Problem 
 
For IND/IDE protocols: 
The SAE report should be completed as per above instructions. If appropriate, the report will 
be forwarded to the FDA by the IND Office 
 
 
17.2.1  Adverse Event Reporting to  Novartis 
 
To ensure patient safety, every SAE, regardless of suspected causality, occurring after the 
patient has provided the main informed consent and until at least 30 days after the patient 
has stopped study treatment must be reported to Novartis within 24 hours of learning of its 
occurrence. 
Any SAEs experienced after this 30 days period should only be reported to Novartis if the 
investigator suspects a causal relationship to the study treatment. Recurrent episodes, 
complications, or progression of the initial SAE must be reported as follow-up to the original 
episode within 24 hours of the investigator receiving the follow-up information. An SAE 
occurring at a different time interval or otherwise considered completely unrelated to a 
previously reported one should be reported separately as a new event. 
Information about all SAEs is collected and recorded on the Serious Adverse Event Report 
Form; all applicable sections of the form must be completed in order to provide a clinically 
thorough report. The investigator must assess and record the relationship of each SAE to 
each specific study treatment (if there is more than one study treatment), complete the SAE 
Report Form in English, and send the completed, signed form by fax within 24 hours to the 
oncology Novartis Drug Safety and Epidemiology (DS&E) department - Fax: (877-778-9739). 
The original copy of the SAE Report Form and the fax confirmation sheet must be kept with 
the case report form documentation at the study site. 
Follow-up information is sent to the same contact(s) to whom the original SAE Report Form 
was sent, using a new SAE Report Form stating that this is a follow-up to the previously 
reported SAE and giving the date of the original report. Each re-occurrence, complication, or 
progression of the original event should be reported as a follow-up to that event regardless of 
when it occurs. The 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 withdrew from study participation.

If the SAE is not previously documented in the Investigator’s Brochure or Package Insert 
(new occurrence) and is thought to be related to the Novartis study treatment, an oncology 
Novartis Drug Safety and Epidemiology (DS&E) department associate may urgently require 
further information from the investigator for Health Authority reporting. Novartis may need to 
issue an Investigator Notification (IN), to inform all investigators involved in any study with 
the same drug that this SAE has been reported. Suspected Unexpected Serious Adverse 
Reactions (SUSARs) will be collected and reported to the competent authorities and relevant 
ethics committees in accordance with Directive 2001/20/EC or as per national regulatory 
requirements in participating countries. 
Pregnancies 
 
To ensure patient safety, each pregnancy occurring while the patient is on study treatment 
must be reported to Novartis within 24 hours of learning of its occurrence. The pregnancy 
should be followed up to determine outcome, including spontaneous or voluntary termination, 
details of the birth, and the presence or absence of any birth defects, congenital 
abnormalities, or maternal and/or newborn complications. 
Pregnancy should be recorded on a Clinical Trial Pregnancy Form and reported by the 
investigator to the oncology Novartis Drug Safety and Epidemiology Department (DS&E). 
Pregnancy follow-up should be recorded on the same form and should include an 
assessment of the possible relationship to the study treatment any pregnancy outcome. Any 
SAE experienced during pregnancy must be reported on the SAE Report Form. 
Warnings and precautions 
 
Additional safety information collected between IB updates will be communicated in the form 
of Investigator Notifications. This information will be included in the patient informed consent 
and should be discussed with the patient during the study as needed 
18.1 
INFORMED CONSENT PROCEDURES 
 
Before protocol-specified procedures are carried out, consenting professionals will explain  
full details of the protocol and study procedures as well as the risks involved to participants 
prior to their inclusion in the study. Participants will also be informed that they are free to 
withdraw from the study at any time. All participants must sign an IRB/PB-approved consent 
form indicating their consent to participate. This consent form meets the requirements of the 
Code of Federal Regulations and the Institutional Review Board/Privacy Board of this Center. 
The consent form will include the following: 
1. The nature and objectives, potential risks and benefits of the intended study. 
2. The length of study and the likely follow-up required.
