Introduction 
1.1 
Colon Cancer 
1.1.1 
Background 
Colorectal cancer (CRC) is a significant cause of cancer mortality. 
The worldwide incidence of CRC in 2000 was estimated as 944,700 
cases (males: 498,000; females: 446,000 cases) (1). In the United 
States (US) colorectal cancer accounts for approximately 11% of all 
cancer deaths (2). At diagnosis, 40% of the world’s CRC population 
have metastatic or “synchronous metastases.” In the US, 
approximately 20% of newly diagnosed patients with CRC will have 
synchronous metastatic cancer (3). Approximately 25% of patients 
with localized disease at diagnosis will ultimately develop metastatic 
disease.  Unfortunately only a small number of patients with stage IV 
cancer can be cured with multimodality therapy. The majority of 
patients with metastatic, stage IV CRC will ultimately die of their 
disease (4).  
Newly developed, and now standard, therapies for patients with stage 
IV CRC have dramatically improved survival and enhanced quality of 
life.  Thus, in the U.S., initial therapy with combinations of 5-
fluorouracil (5FU) and oxaliplatin (FOLFOX) or 5FU and irinotecan 
(FOLFIRI) have increased response rates to approximately 45 percent 
(5). The addition of bevacizumab to either FOLFOX or FOLFIRI has 
produced response rates of 60%.  Indeed, for approximately eight 
percent of patients with stage IV CRC, the addition of surgery to 
successful chemotherapy will produce a cure (6). Upon progression 
after so-called “first-line therapy,” approximately 20% of patients will 
respond to a second systemic treatment combination. Most important, 
median survival for patients with stage IV CRC is now approaching 
2.5 years (7). It is likely that with a better understanding of how to 
incorporate intratumoral molecular parameters such as mutations in 
the k-ras gene and/or quantitation of a tumor’s repair genes such 
ERCC-1 or XRCC-1 and/or targets such as thymidylate synthase into 
treatment strategies, complete responses and cure rates will continue 
to improve.  
1.1.2 
First Line therapy 
A series of clinical trials in the first line therapy of metastatic CRC 
have improved survival from a median of 12 months to nearly 24 
months.  A series of trial showed that combination therapy using 
oxaliplatin (FOLFOX4) or irinotecan (IFL or FOLFIRI) gave improved 
RR, OS and PFS compared with FU and LV bolus or infusion therapy. 
This was confirmed in the N971 US Intergroup trial showing improved 
RR, OS and PFS for FOLFOX compared with the control arm of IFL 
(5).  Shortly thereafter a randomized trial of IFL with or without 
bevacizumab showed and improved HR for PFS and OS for the 
addition of the anti-VEGF antibody. This has been adopted into 
standard practice with all 5FU based first line therapies, including 
FOLFIRI or FOLFOX.  A more recent study (NO16966) demonstrated 

ECOG-ACRIN 
E7208 
Cancer Research Group 
Version Date: March 22, 2016

improved PFS with the addition of bevacizumab to either FOLFOX or 
CapeOX therapy, though of a smaller benefit due to early stopping of 
chemotherapy (7). As FOLFOX has become the standard first-line 
chemotherapy platform, particularly in the US, second line therapy 
has relied on irinotecan based programs. 
1.1.3 
Second Line Therapy 
A study performed by the GERCOR demonstrated that the sequence 
FOLFOX followed by FOLFIRI was equivalent to the reverse 
sequence (8). As a result, US practice has evolved to use irinotecan 
based regimens as second-line therapy.  Either FOLFIRI or irinotecan 
seem equally useful in this situation and either may be used as there 
is no study showing a synergistic effect of fluoropyrimidines with 
irinotecan.  In the GERCOR multi-center study, patients with 
advanced CRC were treated with FOLFOX followed by FOLFIRI at 
the time of progression or the reverse sequence. In the FOLFOX first 
arm, the response rate for second line FOLFIRI was 4% and PFS was 
2.5 months.  A larger second line study was performed to examine the 
role of the anti-EGF antibody, cetuximab as second line therapy on 
patients progressing on FOLFOX. In this 1300 patient study, the 
subjects were randomized to irionotecan alone or irinotecan plus 
cetuximab (9).  The patient populations were not selected for Kras 
status.  Again the response rate for second line irinotecan was 4.2% 
and PFS was 2.6 months (n = 650).   
Recent reports of the predictive value of K-ras gene mutation (36,37) 
have demonstrated convincingly that patients with mutations in codon 
12 and 13 (as determined by RT-PCR from FFPET) do not benefit 
from the use of anti-EGFR antibodies, either as single agent or in 
combination with chemotherapy programs (10). As such, two 
treatment tracks exist for second-line therapy, based on cetuximab 
use in the K-ras wild-type group and irinotecan based therapy alone in 
those with Kras mutations.  In this study, the patient population will be 
limited to those with Kras wild-type status, as both arms will receive 
cetuximab and irinotecan.   
1.1.4 
Biweekly Dosing of Cetuximab 
Cetuximab is approved for previously treated colon cancer with non-
mutated K-ras (“wild type”).  The standard dose and schedule is 400 
mg/m2 loading dose x 1, then weekly 250 mg/m2.  Because of the long 
half-life of therapeutic monoclonal antibodies, such as cetuximab , 
many such agents have alternate dosing schedules of q2 weeks or 
even q3 weeks.  In this study we have chosen the dose of 500 mg/m2 
every two weeks, for the reasons detailed below, and also to facilitate 
co-administration with the irinotecan (180 mg/m2) biweekly schedule. 
Data supporting the biweekly dose of cetuximab 500 mg/m2 have 
been presented and published.  Tabernero, et al (Tabernero, 
Cervantes, Martinelli, et. Al, J Clin Oncol, 24 (18 Suppl), 142s) 
performed a phase I/PK study demonstrating equivalent 
pharmacokinetic parameters for the drug on the q2w schedule.  10 
patients treated on the standard dose/schedule were used in 
comparison. No significant differences were seen with respect to

AUC, half-life, or steady-state clearance between the two schedules 
(Table 1).  In addition, the Phase I portion of the study escalated 
cetuximab dose to achieve a gr 2-3 skin rash, reaching doses of 700 
mg/m2 q2w safely. The study was continuing at the time of 
presentation.

This combination of irinotecan 180 mg/m2 and cetuximab 500 mg/m2 
q2w has also been reported in a Spanish phase II study (Martin-
Martorell, et.al. Br J Ca 99: 455-458, 2008). Forty patients were 
treated and a response rate of 23% was reported (compared with 
20% in the EPIC trial, N =1147), with a Disease Control Rate of 60%.  
Median time to progression was 3.4 months and overall survival was 8 
months.  This also is approximately equivalent to the cetuximab arm 
of the EPIC trial.  Toxicity of grade 3-4 severity was reported as 
diarrhea = 10%, neutropenia = 7.5% and skin toxicity = 7.5%, which 
are all somewhat lower than similarly reported toxicity rates in the 
EPIC trial.   In short, this phase II study suggests the activity and 
toxicity is not substantially different using irinotecan and cetuximab 
q2w compared with irinotecan every 3 weeks with weekly cetuximab.  
This biweekly schedule has been widely adopted in practice by US 
oncologists. 
1.2 
Vascular Endothelial Growth Factor and Angiogenesis 
Angiogenesis, the formation of new capillaries and blood vessels, is a tightly-
controlled, multistep process that is a component of normal physiology (including 
development of the embryonic vasculature, wound healing, ovulation, and 
menstruation). Pathologic angiogenesis contributes to tumor growth and 
metastasis, as well as other human diseases such as diabetic retinopathy, 
rheumatoid arthritis, and psoriasis (11-13). A number of growth factors have 
been identified as positive regulators of angiogenesis, including members of the 
vascular endothelial growth factor (VEGF) family, basic fibroblast growth factor, 
transforming growth factor alpha, transforming growth factor beta, tumor necrosis 
factor, platelet-derived endothelial growth factor, hepatocyte growth factor, 
angiogenin, interleukin-8, and placental growth factor (14,15). VEGF-A is one of 
several related cytokines; it is distinct in that it acts as an endothelial cell-specific 
mitogen and is the growth factor most consistently found in conditions associated 
with angiogenesis (16-19). The biological activity of VEGF-A (hereafter VEGF) is 
principally mediated by two structurally-related, high affinity tyrosine kinase 
receptors: the 180 kDa fms-like tyrosine kinase (VEGFR-1 or Flt-1) (20,21); and 
the 200 kDa receptor (VEGFR-2 or kinase insert domain-containing receptor 
[KDR]), or its murine homologue, fetal liver kinase-1 (Flk-1)(20,21).  Targeted 
deletion of genes encoding VEGF, VEGFR-1, or VEGFR-2 in mice is lethal to the 
embryo, demonstrating the physiological importance of the VEGF pathway in

10 
blood vessel formation.  Mice lacking even a single VEGF allele die prior to birth 
due to vascular abnormalities (24,25). VEGFR-2-deficient mice have impaired 
blood island formation and lack mature endothelial cells (26), whereas VEGFR-1 
null embryos have abundant endothelial cell-like cells, but fail to develop normal 
vasculature (27). 
1.3 
The Role of VEGF and VEGFR-2 in Angiogenesis and Tumor Growth 
The importance of VEGF and VEGFR-2 in angiogenesis and tumor growth has 
been demonstrated in several animal models.  VEGFR-2 expression is 
associated with activated endothelium and is strongly upregulated in tumor 
endothelium (16,28). Inhibiting the function of the VEGF/VEGFR-2 pathway via a 
number of approaches, including anti-VEGF antibodies, anti-VEGFR-2 
antibodies, anti-VEGF antisense ribonucleic acid expression, VEGF-based 
immunotoxins, soluble VEGF receptors, ribozymes to VEGF receptors, and small 
molecule VEGFR-2 tyrosine kinase inhibitors, has been shown to inhibit new 
blood vessel formation and tumor growth in a variety of animal models (29-32). 
VEGF and VEGFR-2 are overexpressed in the great majority of human cancers, 
including carcinomas of the gastrointestinal tract, pancreas, breast, cervix, 
bladder, ovary, uterus, endometrium, and kidney; Kaposi’s sarcoma; 
glioblastoma multiforme; and hemangioblastomas.  In addition, messenger 
ribonucleic acid for both VEGFR-1 and VEGFR-2 is greatly upregulated in tumor-
associated endothelial cells, but not in the vasculature of the surrounding normal 
tissue.  A correlation between VEGFR-2 expression and tumor microvessel 
density has been associated with poor prognosis, advanced disease, increased 
risk of metastasis and recurrence, and lower relapse-free survival in patients with 
a variety of cancers (13,32). 
Accumulating evidence suggests that the dual autocrine/paracrine mechanism 
also may play an important role in the growth and metastasis of certain solid 
tumors. For example, a VEGF/VEGFR autocrine loop was proposed as a 
mediator of growth and metastasis of several types of tumors, including 
carcinomas of prostate, ovary, pancreas, and breast; malignant pleural 
mesothelioma; and melanoma (32). These observations suggest that anti-
VEGFR-2 antibodies may have potential as antiangiogenic and antitumor agents. 
1.4 
IMC-1121B (Ramucirumab) 
Ramucirumab is a recombinant human monoclonal antibody (MAb) of the 
immunoglobulin G, subclass 1 (IgG1) that specifically binds to the extracellular 
domain of VEGFR-2 with high affinity.  This antibody potently blocks the binding 
of the VEGF ligand to VEGFR-2, inhibits VEGF-stimulated activation of both 
VEGFR-2 and p44/p42 MAP kinases, and neutralizes VEGF-induced 
mitogenesis of human endothelial cells. 
Ramucirumab has been shown to block the interaction of VEGF and VEGFR-2 
(with a concentration that inhibits binding by 50% of approximately 1 nM), and to 
inhibit VEGF-stimulated proliferation of endothelial cells and VEGF induced 
migration of human leukemia cells (33,34). 
Preclinical pharmacodynamic data demonstrate that Ramucirumab binds 
specifically and with high affinity to the VEGFR-2, and is capable of inhibiting 
certain in vitro biological processes.  These include VEGF/VEGFR-2 interaction, 
VEGF-stimulated VEGFR-2 activation, proliferation of human endothelial cells, 

ECOG-ACRIN 
E7208 
Cancer Research Group 
Version Date: March 22, 2016 
11 
VEGF-induced migration of human leukemia cells, and VEGF-induced 
phosphorylation of VEGFR-2 in both human umbilical vein endothelial cells and 
porcine aortic endothelial cells engineered to overexpress VEGFR-2 (34).  These 
processes are likely involved in tumor angiogenesis.  Potent angiogenic and 
antitumor effects are observed when DC101, an antibody to murine VEGFR-2, is 
administered to mice bearing syngeneic tumors or human tumor xenografts.  The 
results of these preclinical pharmacodynamic studies support the investigation of 
Ramucirumab in the treatment of solid tumors. 
Two repeat-dose toxicology studies (5 weeks and 39 weeks) were conducted in 
cynomolgus monkeys.  In the 5-week repeat-dose study, Ramucirumab was 
administered intravenously at doses of 0, 4, 12, or 40 mg/kg.  There were no 
Ramucirumab -related effects seen in clinical signs, body weights, food 
consumption, urinalysis, blood pressure, hematology, coagulation, and serum 
chemistry.  There were also no Ramucirumab -related effects found at gross 
pathology evaluation.  Histopathology evaluation revealed focal muscle fiber 
degeneration and mononuclear cell infiltration in skeletal muscle (quadriceps 
femoris) in test article-treated animals only.  These effects were concluded to be 
not treatment-related due to the focal nature of the lesions and the low incidence 
in females.  The Ramucirumab injection sites had mild reactions consisting of 
mononuclear cells or mononuclear and polymorphonuclear cells in perivascular 
areas.  Based on the results of this study, intravenous administration of 
Ramucirumab was well tolerated at dose levels from 4 to 40 mg/kg for four doses 
and the no-observable-effect level (NOEL) in this study was ≥ 40 mg/kg, the 
highest dose administered. 
In the 39-week repeat-dose study, Ramucirumab was administered via 
intravenous infusion at dose levels of 5, 16, and 50 mg/kg to cynomolgus 
monkeys for 11 weekly doses over 12 weeks (females only) or weekly for 39 
weeks (males and females) of study.  There were no Ramucirumab -related 
effects noted in animals treated at up to 50 mg/kg for 12 weeks of study.  
Thickening and osteochondropathy of the epiphyseal growth plate was noted at 
5 mg/kg and above in animals treated for 39 weeks.  This was an anticipated 
mechanism-related effect.  Treatment with Ramucirumab resulted in renal toxicity 
at the 16- and 50-mg/kg dose levels after 39 weeks.  In addition, clinical 
chemistry and urinalysis parameters indicated that the renal toxicity had 
manifested at 16 mg/kg and 50 mg/kg after 26 weeks.  A NOEL of Ramucirumab 
could not be established when administered intravenously once a week for 39 
weeks in male or female cynomolgus monkeys. 
1.4.1 
Clinical Studies 
Two Phase 1 studies are being conducted to evaluate the safety and 
antitumor effects of Ramucirumab administered either weekly (CP12-
0401) or every other week or every third week (CP12-0402) at doses 
ranging from 2 mg/kg through 20 mg/kg in patients with advanced 
cancer.  Two mechanism-based, dose-limiting toxicities were 
observed at the weekly schedule of 16 mg/kg, symptomatic 
hypertension and deep vein thrombosis, both of which occurred after 
several cycles of Ramucirumab infusion.  Thus, the maximum 
tolerated dose for the weekly study was determined as 13 mg/kg 
administered on a weekly schedule.  The MTD has not been reached 
for the every other week or the every third week schedules.

A total of 37 patients have been enrolled in study CP12-0401 
(Ramucirumab administered weekly) at doses of 2 to 16 mg/kg; this 
patient population includes 23 males and 14 females, ranging in age 
from 36 to 76 years.  Adverse events ≥ grade 3 considered to be at 
least possibly-related to Ramucirumab were reported in 10 patients 
and include hypertension, deep vein thrombosis, headache, vomiting, 
anemia, increased amylase, hyperphosphatemia, and proteinuria. To 
date, four confirmed partial responses (in melanoma, gastric and 
neuroendocrine tumors, and uterine leiomyosarcoma) have been 
reported, and at least nine patients have experienced prolonged 
stable disease (> 6 months).  At least one of these patients had been 
treated previously with the anti-VEGF agent bevacizumab. 
Importantly, other evidence of clinical benefit has also been noted.  In 
particular, several patients (melanoma [1 patient], gastric cancer [1 
patient], and thyroid cancer [2 patients]) experienced significant pain 
relief along with reductions in analgesic requirements, and a patient 
with refractory pleural effusions experienced significant reductions in 
fluid retention and a lower frequency of thoracenteses. 
A total of 25 patients have been enrolled in study CP12-0402 
(Ramucirumab administered every other week or every 3 weeks), of 
whom 24 have received treatment at doses ranging from 6 mg/kg to 
20 mg/kg.  The MTD has not been reached for the every-other-week 
or the every-third-week schedules; the study is ongoing but currently 
closed to enrollment. 
A total of 13 of 24 (54.2%) patients to date have experienced events 
that were considered possibly, probably, or definitely related (related) 
to treatment with Ramucirumab. The most common (> 10%) 
treatment-related events were proteinuria (16.7%), diarrhea (12.5%), 
and hypertension (12.5%).  Adverse events ≥ Grade 3 considered to 
be at least possibly related to Ramucirumab were reported in three 
patients and include duodenal ulcer hemorrhage (Grade 4), 
hypertension, and fatigue. 
As of 1 September 2008, 19 patients were evaluable for response; of 
these patients, 12 have experienced a best overall response of stable 
disease, including five with SD ≥ 6 months. These five patients had 
cancers of the colon (2 patients), liver (2 patients), and kidney (1 
patient). Three of these patients have had ongoing SD for > 10 
months duration. Six patients remain on study (two patients in the 
10-mg/kg every other week cohort, two patients in the 15-mg/kg every 
three week cohort, and two patients in the 20-mg/kg every three week 
cohort). 
As of January 18, 2010, at least 454 patients had received at least 
one dose of IMC-1121B on ImClone sponsored phase 1-2 studies and 
at least 83 patients had received at least one dose of blinded IMC-
1121B/placebo on ImClone sponsored randomized phase III studies.  
Data safety monitoring committee reviews have been performed 
regularly on phase 2 studies in melanoma (involving combination with 
dacarbazine), prostate cancer (involving combination with 
mitoxantrone/prednisone), ovarian cancer (monotherapy), colorectal

cancer (involving combination with mFOLFOX-6) and breast cancer 
(involving combination with docetaxel). 
Some of the published data include:  
a) The Phase 1 Monotherapy Study (Spratlin et al. J Clin Oncol 
2010; 28: e-published 4 Jan 2010).  37 patients treated with 
advanced, refractory solid tumors.  Ramucirumab was given 
weekly as monotherapy.  Reported results included PR in 4/27 
(15%) patients with measurable disease and PR or SD ≥ 6 months 
in 11/37 (30%) of patients. 
b) Initial Phase 2 Presentation for metastatic, TKI-refractory Renal 
Cancer (Garcia et al. ESMO/ECCO Berlin 2009. 40 patients were 
given ramucirumab 8mg/kg q 2 wk. Of these, 50% had prior 
sunitinib, 35% prior sunitinib and sorafenib and15% prior 
sorafenib. The preliminary median PFS is 6 months and 3/40 (7%) 
had confirmed PR. The drug was well-tolerated. 
Additional phase II studies are underway in RCC, HCC, melanoma, 
prostate cancer, NSCLC, ovarian cancer, GBM, colorectal, breast and 
bladder cancer. Phase 3 studies are underway in breast cancer, with 
others planned in HCC, colorectal cancer. Further phase 2 results will 
be presented at GU ASCO (RCC update), ASCO (melanoma, HCC, 
NSCLC) in 2010. 
Additional toxicities (observed in preliminary phase 2 studies) and 
potential toxicities (based on the known toxicity profiles of agents 
which inhibit the VEGF or VEGF-receptor pathway) are presented in 
the most recent Investigator Brochure.  No additional safety patterns 
have been demonstrated conclusively beyond those observed, 
discussed and reported in the most recent Investigator Brochure. 
1.4.2 
Dose Rationale 
Nonclinical data obtained from a murine BxPC-3 xenograft model 
have demonstrated that the efficacy of DC101, a murine analogue to 
Ramucirumab, was evident in vivo at trough concentrations of 18 
µg/mL. The target serum concentration for Ramucirumab is 
hypothesized to be one that maintains Ramucirumab at trough plasma 
concentrations ≥ 20 µg/mL. Preliminary pharmacokinetic (PK) data 
from studies CP12-0401 and CP12-0402 indicate that the minimum 
20 µg/mL target trough concentrations are attainable.  In the every-
other-week protocol, following the initial dose of 6 mg/kg, mean serum 
trough concentrations (immediately prior to the next dose) of 
Ramucirumab were 31 µg/mL (range: 18–64 µg/mL [n=7]).  Analysis 
of the initial 8-mg/kg dose at the same time point yielded a mean 
serum trough concentration of 115 µg/mL (range: 18 - 205 µg/mL 
[n=3]).  To provide a suitable margin above the 20 µg/mL 
Ramucirumab target concentration, the proposed dose and regimen 
for this Phase 3 study will be 8 mg/kg Ramucirumab given every other 
week.  At this dose and regimen, the half-life following the initial 
infusion of IMC-Ramucirumab is approximately 155 hours; following 
later infusions during the first cycle, the half-life is approximately 
300 hours, suggesting that steady state is being approached.  
Supporting this observation is the finding that as the dose of IMC-

ECOG-ACRIN

Ramucirumab was increased from 6 to 13 mg/kg, clearance 
decreased from 0.237 mL/hr/kg to a plateau of 0.06 mL/hr/kg 
(clearance at 8 mg/kg was approximately 0.113 mL/hr/kg). 
1.5 
Summary and Study Rationale 
First line therapy of CRC at this time generally includes bevacizumab plus 
combination chemotherapy, which most commonly in the US includes oxaliplatin, 
leucovorin and 5FU (a modified FOLFOX regimen).  Whether continuing anti-
angiogenic therapy after first line therapy is beneficial remains an open question.  
Studies to date have shown benefit for addition of bevacizumab in first line 
therapy and in second line therapy in bevacizumab-naïve patients. In the case of 
patients with Kras wild-type cancers, standard second line therapy would 
generally include irinotecan with cetuximab, based on the EPIC trial which 
demonstrated a doubling in PFS (9).  We have chosen this regimen as the 
control arm for this study, which will compare addition of the anti-VEGFR 
antibody, Ramucirumab.  The goal of this study is to show improved PFS with the 
addition of a novel second line anti-angiogenic antibody.

Summary of Toxicity Review 
The study was closed to accrual on June 14, 2012 after 35 registrations were 
accrued as per pre-planned toxicity review. 18 patients (17 treated; one case 
never started assigned therapy) were accrued to Arm A (IC) and 17 (16 treated; 
one case was a duplicate registration) to Arm B (ICR). AdEERS Reporting was 
reviewed and real time data were obtained on all treated patients. It was clear 
that more toxicity was seen in Arm B. Worst toxicity per patient is seen in the 
figure below.  The overall grade 3-5 toxicity rates were 17% for Arm A and 75% 
for Arm B. There were 2 toxic deaths in Arm B. Toxicities of higher incidence in 
Arm B included neutropenia, mucositis, diarrhea and GI perforation (including 
peri-anal abscess).  In addition mean dose given in Arm B (mean % RDI) was 
considerably lower in Arm B:  65% for irinotecan, 85% for cetuximab and 92% for 
ramucirumab (even though no dose reductions were allowed in the protocol). 
This compares to 99% irinotecan and 98% cetuximab average %RDI in Arm A. 
Furthermore, only 3/17 patients in Arm A required dose reduction, compared to 
15/16 in Arm B. On the other hand with a median of 8 cycles preliminary analysis 
showed that fewer patients in Arm B went off treatment for progression compared 
with Arm A, and more remained on treatment at the time of the analysis. Of the 
17 treated in Arm A, 8 out of 9 patients off study had progression (PD), while in 
Arm B, of the 16 treated, only 1 out of 5 who went off study, went off for PD. 
These findings suggest potential benefit for the addition of ramucirumab among 
patients who can tolerate therapy. Therefore, we propose a reduced dose 
regimen in Arm C (modified ICR) with irinotecan 150 mg/m2, cetuximab 400 
mg/m2 and ramucirumab 6 mg/m2 as starting doses, more strict eligibility criteria, 
and more aggressive dose modifications for toxicity.  Because those patients on 
protocol who did tolerate the ICR regimen at the reduced doses seemed to stay 
on study longer, we believe the study should be continued as modified at those 
lower doses. The Arm C starting doses are equal to the actual “percent 
recommended dose intensity” received by patients in Arm B.

Patient Enrollment 
Patient registration can occur only after pre-treatment evaluation is complete, eligibility 
criteria have been met, and the study site is listed as ‘approved’ in the CTSU RSS. 
Patients must have signed and dated all applicable consents and authorization forms. 
Patient enrollment will be facilitated using the Oncology Patient Enrollment 
Network (OPEN). OPEN is a web-based registration system available on a 24/7 
basis. To access OPEN, the site user must have an active CTEP-IAM account 
(check at <https://eapps-ctep.nci.nih.gov/iam/index.jsp>) and a 'Registrar' role on 
either the LPO or participating organization roster. 
All site staff will use OPEN to enroll patients to this study. It is integrated with the CTSU 
Enterprise System for regulatory and roster data and, upon enrollment, initializes the 
patient in the Rave database. OPEN can be accessed at https://open.ctsu.org or from 
the OPEN tab on the CTSU members’ side of the website at https://www.ctsu.org. 
Prior to accessing OPEN site staff should verify the following: 
• 
All eligibility criteria have been met within the protocol stated timeframes.  
•

patients enrolled, as well as those who will enroll in future studies 
using similar agents.  
• 
Routine reporting: Adverse events are reported in a routine 
manner at scheduled times during a trial (please refer to the 
E7208 Forms Packet for the list of forms with directions and 
timeframes for routine adverse event reporting).  
• 
Expedited reporting: In addition to routine reporting, certain 
adverse events must be reported in an expedited manner via 
CTEP-AERS for timelier monitoring of patient safety and care. The 
following sections provide information and instructions regarding 
expedited adverse event reporting. 
5.2.2 
Terminology 
• 
Adverse Event (AE): Any untoward medical occurrence 
associated with the use of a drug in humans, whether or not 
considered drug related. Therefore, an AE can be ANY 
unfavorable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease temporally associated 
with the use of a medicinal product, whether or not considered 
related to the medicinal product.  
• 
Attribution:  An assessment of the relationship between the 
adverse event and the protocol treatment, using the following 
categories. 
ATTRIBUTION 
DESCRIPTION 
Unrelated 
The AE is clearly NOT related to treatment 
Unlikely 
The AE is doubtfully related to treatment 
Possible 
The AE may be related to treatment 
Probable 
The AE is likely related to treatment 
Definite 
The AE is clearly related to treatment 
• 
CAEPR (Comprehensive Adverse Events and Potential Risks 
List):  An NCI generated list of reported and/or potential AEs 
associated with an agent currently under an NCI IND.  Information 
contained in the CAEPR is compiled from the Investigator’s 
Brochure, the Package Insert, as well as company safety reports.   
• 
CTCAE:  The NCI Common Terminology Criteria for Adverse 
Events provides a descriptive terminology that is to be utilized for 
AE reporting.  A grade (severity) is provided for each AE term.   
• 
Hospitalization (or prolongation of hospitalization):  For AE 
reporting purposes, a hospitalization is defined as an inpatient 
hospital stay equal to or greater than 24 hours.   
• 
Life Threatening Adverse Event:  Any AE that places the 
subject at immediate risk of death from the AE as it occurred.   
• 
Serious Adverse Event (SAE): Any adverse event occurring at 
any dose that results in ANY of the following outcomes:  
• 
Death

• 
A life-threatening adverse event  
• 
Inpatient hospitalization or prolongation of existing 
hospitalization (for ≥ 24 hours).  
• 
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 a serious adverse event when it may jeopardize 
the patient and may require medical or surgical intervention to 
prevent one of the outcomes listed in this definition. 
5.2.3 
Reporting Procedure 
This study requires that expedited adverse event reporting use 
CTEP’s Adverse Event Reporting System (CTEP-AERS). CTEP’s 
guidelines for CTEP-AERS can be found at http://ctep.cancer.gov.  A 
CTEP-AERS report must be submitted electronically to ECOG-ACRIN 
and the appropriate regulatory agencies via the CTEP-AERS Web-
based application located at http://ctep.cancer.gov. 
In the rare event when Internet connectivity is disrupted a 24-hour 
notification is to be made by telephone to  
• 
the AE Team at ECOG-ACRIN (617-632-3610) for Arms A, B and 
C and 
• 
the FDA (1-800-332-1088) for Arm A 
An electronic report MUST be submitted immediately upon re-
establishment of internet connection 
Supporting and follow up data:  Any supporting or follow up 
documentation must be faxed to ECOG-ACRIN (617-632-2990), 
Attention: AE within 48-72 hours. In addition, supporting or follow up 
documentation must be faxed to  
• 
the FDA (800-332-0178), for Arm A, in the same timeframe.  
NCI Technical Help Desk:  For any technical questions or system 
problems regarding the use of the CTEP-AERS application, please

5.2.4 
Determination of Reporting Requirements 
Many factors determine the reporting requirements of each individual 
protocol, and which events are reportable in an expeditious manner, 
including:   
• 
the phase (0, 1, 2, or 3) of the trial  
• 
whether the patient has received an investigational or commercial 
agent or both 
• 
the seriousness of the event 
• 
the Common Terminology Criteria for Adverse Events (CTCAE) 
grade

5.4 
Dose Modifications  
All toxicities should be graded according to the NCI Common Terminology 
Criteria for Adverse Events (CTCAE) version 4.0. 
Version 4.0 of the CTCAE is identified and located on the CTEP website at 
(http://ctep.cancer.gov/protocolDevelopment/electronic_applications/ctc.ht
m. All appropriate treatment areas should have access to a copy of version 
4.0 of CTCAE. 
5.4.1 
General Considerations 
a. A new cycle of treatment may begin when the ANC is ≥ 1,500/mcl, 
the platelet count is ≥ 75,000/mcl, and any treatment-related GI 
toxicity is resolved to ≤ Grade 1.  
b. If the initiation of a new cycle, or treatment during a cycle is 
delayed for ≥ 4 weeks, the patient should be removed from 
protocol treatment.  
c. Held doses are not to be made up. 
d. If one therapeutic agent is permanently discontinued secondary to 
toxicity, then therapy with the other study agents should continue 
and the patient should remain on-study with full adherence to all 
protocol-related requirements 
e. In the event of serious or life-threatening conditions, hold the 
offending agent. If the patient is to continue on therapy, all agents 
should be held until the toxicity resolves to grade < 2. 
f. Dose reductions for all agents are as follows: 
ARM

5.4.2 
Hematologic toxicities 
No Ramucirumab or cetuximab dose modifications (or delays) will be 
made for hematologic toxicity.  Continue Ramucirumab or cetuximab 
when irinotecan is held for hematologic toxicities. 
Grade 
Dose Modification 
2 
Reduce irinotecan one dose level at the next cycle.  For subsequent cycles, resume at 
the previous dose levels, provided ANC ≥ 1,500/mcl and platelets ≥ 75,000/mcl. 
3-4 
Hold irinotecan. If counts recover to ANC ≥ 1,500/mcl and platelets ≥ 75,000/mcl, 
irinotecan may be resumed at one lower dose level at next cycle. For subsequent 
cycles, continue at the reduced dose levels from the previous cycle. 
Febrile 
neutropenia 
Hold irinotecan.  If fever resolves and counts recover to ANC ≥ 1,500/mcl and platelets 
≥ 75,000/mcl, irinotecan may be resumed at one lower dose level at next cycle.  For 
subsequent cycles, continue at the reduced dose levels from the previous cycle. 
5.4.3 
Diarrhea 
No Ramucirumab dose delay will be made for diarrhea.  Continue 
Ramucirumab when other agents are held. Dose modifications should 
be made for toxicity only when patient is receiving intensive 
loperamide therapy. 
Grade 
Dose Modification 
2 
Be sure intensive loperamide is being taken. For subsequent cycles, resume 
all agents at the previous dose levels, provided diarrhea has fully resolved 
before restarting treatment. 
3 
Be sure intensive loperamide is being taken. If so, and grade 3 diarrhea lasts 
longer than 48 hours, reduce irinotecan one dose level. Do not treat again 
until the diarrhea resolves to ≤ grade 2. 
4 
Be sure intensive loperamide is being taken. Hold irinotecan. If diarrhea 
resolves to ≤ grade 2, irinotecan and cetuximab should be resumed at one 
lower dose level for subsequent cycles. For subsequent cycles, continue both 
agents at the reduced dose levels from the previous cycle. 
5.4.4 
Nausea and/or vomiting 
These dose modifications for nausea and/or vomiting should be made 
only if they persist/occur despite two treatments with adequate 
(combination) antiemetics therapy.   
No Ramucirumab or cetuximab dose modifications (or delays) will be 
made for nausea/vomiting. Continue Ramucirumab or cetuximab 
when irinotecan is held. 
Grade 
Dose Modification 
3-4 
Reduce irinotecan one dose level. For subsequent cycles, continue irinotecan 
at the reduced dose level from the previous cycle.

Grade 
Dose Modification 
2 
Reduce irinotecan one dose level for subsequent cycles. No modifications (or 
delays) will be made for Ramucirumab or cetuximab. 
3 
Hold irinotecan. If mucositis resolves to ≤ Grade 2, resume both irinotecan 
and cetuximab at one lower dose level for subsequent cycles. No 
modifications (or delays) will be made for Ramucirumab. 
4 
Hold ALL protocol treatment. If mucositis resolves to ≤ Grade 2, reduce all 
agents one dose level for all subsequent cycles. 
5.4.6 
Pulmonary Toxicity  
5.4.6.1 
For Grade 2 or worsening pulmonary symptoms unrelated 
to underlying cancer, cetuximab treatment should be 
stopped and symptoms investigated. Cetuximab treatment 
may resume at one lower dose level when symptoms 
resolve to ≤ Grade 1 and cetuximab-related pneumonitis is 
ruled out. 
5.4.6.2 
For ≥ Grade 3 cough, dyspnea, hypoxia, pneumonitis, or 
pulmonary infiltrates, hold cetuximab until interstitial lung 
disease is ruled out. Continue Ramucirumab and 
irinotecan.  Discontinue all protocol treatment if interstitial 
lung disease is confirmed.  
5.4.7 
Hypomagnesemia has been seen with cetuximab. For Grade 3-4 
hypomagnesemia, hold cetuximab until hypomagnesemia resolves to 
≤ Grade 2.  Then restart cetuximab at the -1 dose.  For any grade of 
hypomagnesemia, magnesium supplementation should be provided.  
5.4.8 
Hypertension (Dose delays for Ramucirumab only) 
Treat with anti-hypertensive medication as needed. The goal of BP control should be 
consistent with general medical practice 
Grade 1 
(SBP 120-139 mmHg or DBP 80-89 mm Hg) 
Consider increased BP monitoring; 
start anti-hypertensive medication if 
appropriate

Proteinuria (Dose delays for Ramucirumab only)  
5.4.13.1 
For proteinuria ≥ 2+ or UPC (urinary protein: creatinine 
ratio) > 1.0: Confirm total urine protein with a 24-hour urine 
collection. For 2+ proteinuria, the scheduled dose of 
Ramucirumab may be given while awaiting the results of 
the 24-hour collection. For > 2+ proteinuria, hold 
Ramucirumab while awaiting results of the 24-hour urine 
collection. Other protocol treatment may be continued. If 
proteinuria is 2-3 g/24 hours, hold Ramucirumab until urine 
protein recovers to < 2 g/24 hours, then resume at the -1 
dose level. Continue other protocol treatment. A second 
dose reduction (to 5 mg/kg every other week) is permitted 
if the protein level > 2g/24 hours recurs.  Ramucirumab will 
be discontinued permanently if the protein level is > 3g/24 
hours, if there is a third occurrence of proteinuria > 2 g/24 
hours, or if the protein level does not return to < 2g/24 
hours within 2 weeks.

Infusion Reactions 
Grade 1 
Slow the infusion rate by 50%. 
Monitor the patient for worsening of the condition. 
For subsequent infusions, premedicate with diphenhydramine 
50mg IV (or equivalent); additional premedication may be 
administered at the investigator’s discretion. 
Grade 2 
Stop the infusion. 
Administer diphenhydramine 50mg IV (or equivalent), 
acetaminophen 650 mg orally for fever, and oxygen. 
Resume the infusion at 50% of the prior rate once the infusion 
reaction has resolved or decreased to grade 1; the infusion 
duration should not exceed 2 hours 
For subsequent infusions, premedicate with diphenhydramine 
50mg IV (or equivalent); additional premedication may be 
administered at the investigator’s discretion. 
Grade 3  
and 
Grade 4 
Immediately and permanently discontinue the offending agent. 
Appropriate medical therapy including epinephrine, 
corticosteroids, intravenous antihistamines, bronchodilators, 
and oxygen should be available for use in the treatment of such 
reactions. Patients should be carefully observed until the 
complete resolution of all signs and symptoms.  
For grade 1 or 2 reactions manifesting only as delayed drug fever, see 
Section 5.4.16. 
For grade 4 or allergy related edema and angioedema and 
hypotension, permanently discontinue all medications. 
For a second Grade 1 or 2 infusion reaction, administer 
dexamethasone 10mg IV (or equivalent); then, for subsequent 
infusions, premedicate with diphenhydramine 50mg IV (or equivalent), 
acetaminophen 650 mg orally, and dexamethasone 10mg IV (or 
equivalent). 
5.4.16 
Drug Fever 
In the event of isolated drug fever, the investigator must use clinical 
judgment to determine if the fever is related to the study drug or to an 
infectious etiology. If a patient experiences isolated drug fever, for the 
next dose, pre-treat with acetaminophen or non-steroidal anti-
inflammatory agent (investigator discretion); repeat antipyretic dose 6 
and 12 hours after cetuximab infusion. The infusion rate will remain 
unchanged for future doses.  
If a patient experiences recurrent isolated drug fever following 
premedication and post-dosing with an appropriate antipyretic, the 
infusion rate for subsequent dosing should be 50% of previous rate. If 
fever recurs following infusion rate change, the investigator should 
assess the patient’s level of discomfort with the event and use clinical 
judgment to determine if the patient should receive further cetuximab.

5.5 
Supportive Care 
5.5.1 
All supportive measures consistent with optimal patient care will be 
given throughout the study. 
5.5.2 
Diarrhea Management 
For symptoms of diarrhea and/or abdominal cramping that occur at 
any time during a treatment cycle with irinotecan, patients will be 
instructed to begin taking loperamide. Loperamide should be started 
at the earliest sign of (1) a poorly formed or loose stool or (2) the 
occurrence of 1 to 2 more bowel movements than usual in 1 day or (3) 
an increase in stool volume or liquidity. Loperamide should be taken 
in the following manner: 4 mg at the first onset of diarrhea, then 2 mg 
every 2 hours around the clock until diarrhea-free for at least 12 
hours. Patients may take loperamide 4 mg every 4 hours during the 
night. Loperamide should not be used for more than 48 hours. 
Patients should be provided with loperamide at the initial treatment 
visit so that they have sufficient supply on hand in case antidiarrheal 
support is required. Additional antidiarrheal measures may be used at 
the discretion of the treating physician. Patients should be instructed 
to increase fluid intake to help maintain fluid and electrolyte balance 
during episodes of diarrhea.  
5.5.3 
Antibiotics 
Oral fluoroquinolone treatment should be initiated for any of the 
following:  
• 
Diarrhea persisting for more than 24 hours despite loperamide  
• 
 ANC < 500/mcl (even in the absence of diarrhea or fever) 
• 
 Fever with diarrhea (even in the absence of neutropenia)  
• 
Antibiotic therapy should also be initiated in patients who are 
hospitalized with prolonged diarrhea (even in the absence of 
neutropenia). 
5.5.4 
Lacrimation, rhinorrhea, miosis, diaphoresis, hot flashes, flushing, 
abdominal cramping, diarrhea, or other symptoms of early cholinergic 
syndrome may occur during or shortly after receiving irinotecan. 
Atropine, 0.25-1.0 mg IV or SC may be used to treat these symptoms. 
In patients with troublesome or recurrent symptoms, prophylactic 
administration of atropine shortly before irinotecan therapy may be 
considered. Additional antidiarrheal measures may be used at the 
discretion of the treating physician. Combination anticholinergic 
medications containing barbiturates or other agents (e.g., Donnatal®) 
should not be used because these may affect irinotecan metabolism. 
Anticholinergics should be used with caution in patients with potential 
contraindications (e.g., obstructive uropathy, glaucoma, tachycardia, 
etc.).

Dermatology Management 
Suggested algorithm for management of cutaneous toxicity and 
paronychia: 
In this protocol, acneiform rash and paronychia will be graded 
according to version 4.0 of the NCI-CTCAE definitions of 
rash/desquamation and nail changes. The patient should be followed 
until resolution of these toxicities. 
Acneiform rash and paronychia should be managed according to the 
algorithms in Table 1-1 and Table 1-2. Cetuximab therapy treatment 
adjustments should be made according to Tables 1-3. Cetuximab 
dose reductions will be permanent (i.e., no dose re-escalations).

must also be followed through completion of all protocol therapy.

Measurement of Effect 
6.1 
Antitumor Effect – Solid Tumors 
For the purposes of this study, patients should be re-evaluated for response 
every eight weeks.   
Response and progression will be evaluated in this study using the international 
criteria proposed by the revised Response Evaluation Criteria in Solid Tumors 
(RECIST) guideline (version 1.1) [Eur J Ca 45:228-247, 2009].  Changes in the 
largest diameter (unidimensional measurement) of the tumor lesions and the 
shortest diameter in the case of malignant lymph nodes are used in RECIST. 
• 
The following general principles must be followed: 
1. To assess objective response, it is necessary to estimate the overall 
tumor burden at baseline to which subsequent measurements will be 
compared. All baseline evaluations should be performed as closely as 
possible to the beginning of treatment and never more than four weeks 
before registration. 
2. Measurable disease is defined by the presence of at least one 
measurable lesion. 
3. All measurements should be recorded in metric notation by use of a ruler 
or calipers.  
4. The same method of assessment and the same technique must be used 
to characterize each identified lesion at baseline and during follow-up.  
6.1.1 
Definitions 
Evaluable for Objective Response 
Only those patients who have measurable disease present at 
baseline, have received at least one cycle of therapy, and have had 
their disease re-evaluated will be considered evaluable for response.  
These patients will have their response classified according to the 
definitions stated below.   
(NOTE: Patients who exhibit objective disease progression prior to 
the end of cycle 1 will also be considered evaluable.) 
Evaluable Non-Target Disease Response 
Patients who have lesions present at baseline that are evaluable but 
do not meet the definitions of measurable disease, have received at 
least one cycle of therapy, and have had their disease re-evaluated 
will be considered evaluable for non-target lesion assessment.  The 
response assessment is based on the presence, absence, or 
unequivocal progression of the lesions.  
6.1.2 
Disease Parameters 
Measurable Disease 
Measurable lesions are defined as those that can be accurately 
measured in at least one dimension (longest diameter to be recorded) 
as ≥ 20 mm by chest x-ray, as ≥ 10 mm with CT scan, or ≥ 10 mm 

ECOG-ACRIN 
E7208 
Cancer Research Group 
Version Date: March 22, 2016 
51 
with calipers by clinical exam. All tumor measurements must be 
recorded in millimeters. 
Malignant Lymph Nodes 
To be considered pathologically enlarged and measurable, a lymph 
node must be ≥ 15 mm in short axis when assessed by CT scan (CT 
scan slice thickness recommended to be no greater than 5 mm).  At 
baseline and in follow-up, only the short axis will be measured and 
followed. 
Non-measurable Disease 
All other lesions (or sites of disease), including small lesions (longest 
diameter <10 mm or pathological lymph nodes with ≥ 10 to < 15 mm 
short axis), are considered non-measurable disease. Bone lesions, 
leptomeningeal disease, ascites, pleural/pericardial effusions, 
lymphangitis cutis/pulmonitis, inflammatory breast disease, and 
abdominal masses (not followed by CT or MRI), are considered as 
non-measurable.  Non-measurable also includes lesions that are < 20 
mm by chest x-ray. 
NOTE: 
Cystic lesions that meet the criteria for radiographically 
defined simple cysts should not be considered as malignant 
lesions (neither measurable nor non-measurable) since 
they are, by definition, simple cysts. 
‘Cystic lesions’ thought to represent cystic metastases can be 
considered as measurable lesions, if they meet the definition of 
measurability described above. However, if non-cystic lesions are 
present in the same patient, these are preferred for selection as target 
lesions. 
Target Lesions 
All measurable lesions up to a maximum of 2 lesions per organ and 5 
lesions in 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 (lesions 
with the longest diameter), be representative of all involved organs, 
but in addition should be those that lend themselves to reproducible 
repeated measurements.  It may be the case that, on occasion, the 
largest lesion does not lend itself to reproducible measurement in 
which circumstance the next largest lesion which can be measured 
reproducibly should be selected.   
A sum of the diameters (longest for non-nodal lesions, short axis for 
nodal lesions) for all target lesions will be calculated and reported as 
the baseline sum diameters.  If lymph nodes are to be included in the 
sum, then only the short axis is added into the sum.  The baseline 
sum of the diameters will be used as reference to further characterize 
any objective tumor regression in the measurable dimension of the 
disease.

Cancer Research Group 
Version Date: March 22, 2016 
52 
Non-target Lesions 
All other lesions (or sites of disease) including any measurable lesions 
over and above the 5 target lesions should be identified as non-target 
lesions and should also be recorded at baseline.  Measurements of 
these lesions are not required, but the presence or absence of 
unequivocal progression of each should be noted throughout follow-
up. 
6.1.3 
Methods for Evaluation of Measurable Disease 
All measurements should be taken and recorded in metric notation 
using a ruler or calipers.  All baseline evaluations should be 
performed as closely as possible to the beginning of treatment and 
never more than 4 weeks before registration. 
The same method of assessment and the same technique must be 
used to characterize each identified and reported lesion at baseline 
and during follow-up. Imaging-based evaluation is preferred to 
evaluation by clinical examination unless the lesion(s) being followed 
cannot be imaged but are assessable by clinical exam. 
Clinical Lesions 
Clinical lesions will only be considered measurable when they are 
superficial (e.g., skin nodules and palpable lymph nodes) and ≥10 mm 
in diameter as assessed using calipers (e.g., skin nodules).  In the 
case of skin lesions, documentation by color photography, including a 
ruler to estimate the size of the lesion, is recommended.  
Chest X-ray 
Lesions on chest x-ray are acceptable as measurable lesions when 
they are clearly defined and surrounded by aerated lung.  However, 
CT is preferable.  
Conventional CT and MRI  
This guideline has defined measurability of lesions on CT scan based 
on the assumption that CT slice thickness is 5 mm or less. If CT scans 
have slice thickness greater than 5 mm, the minimum size for a 
measurable lesion should be twice the slice thickness.  MRI is also 
acceptable in certain situations (e.g. for body scans).   
Use of MRI remains a complex issue.  MRI has excellent contrast, 
spatial, and temporal resolution; however, there are many image 
acquisition variables involved in MRI which greatly impact image 
quality, lesion conspicuity, and measurement.  Furthermore, the 
availability of MRI is variable globally.  As with CT, if an MRI is 
performed, the technical specifications of the scanning sequences 
used should be optimized for the evaluation of the type and site of 
disease.  Furthermore, as with CT, the modality used at follow-up 
must be the same as was used at baseline and the lesions should be 
measured/assessed on the same pulse sequence.  It is beyond the 
scope of the RECIST guidelines to prescribe specific MRI pulse 
sequence parameters for all scanners, body parts, and diseases.  

ECOG-ACRIN 
E7208 
Cancer Research Group 
Version Date: March 22, 2016 
53 
Ideally, the same type of scanner should be used and the image 
acquisition protocol should be followed as closely as possible to prior 
scans.  Body scans should be performed with breath-hold scanning 
techniques, if possible. 
PET-CT 
At present, the low dose or attenuation correction CT portion of a 
combined PET-CT is not always of optimal diagnostic CT quality for 
use with RECIST measurements.  However, if the site can document 
that the CT performed as part of a PET-CT is of identical diagnostic 
quality to a diagnostic CT (with IV and oral contrast), then the CT 
portion of the PET-CT can be used for RECIST measurements and 
can be used interchangeably with conventional CT in accurately 
measuring cancer lesions over time.  Note, however, that the PET 
portion of the CT introduces additional data which may bias an 
investigator if it is not routinely or serially performed. 
Ultrasound 
Ultrasound is not useful in assessment of lesion size and should not 
be used as a method of measurement.  Ultrasound examinations 
cannot be reproduced in their entirety for independent review at a 
later date and, because they are operator dependent, it cannot be 
guaranteed that the same technique and measurements will be taken 
from one assessment to the next.  If new lesions are identified by 
ultrasound in the course of the study, confirmation by CT or MRI is 
advised.  If there is concern about radiation exposure at CT, MRI may 
be used instead of CT in selected instances. 
Endoscopy, Laparoscopy 
The utilization of these techniques for objective tumor evaluation is 
not advised.  However, such techniques may be useful to confirm 
complete pathological response when biopsies are obtained or to 
determine relapse in trials where recurrence following complete 
response (CR) or surgical resection is an endpoint. 
Tumor Markers 
Tumor markers alone cannot be used to assess response.  If markers 
are initially above the upper normal limit, they must normalize for a 
patient to be considered in complete clinical response.  Specific 
guidelines for both CA-125 response (in recurrent ovarian cancer) and 
PSA response (in recurrent prostate cancer) have been published 
[JNCI 96:487-488, 2004; J Clin Oncol 17, 3461-3467, 1999; J Clin 
Oncol 26:1148-1159, 2008].  In addition, the Gynecologic Cancer 
Intergroup has developed CA-125 progression criteria which are to be 
integrated with objective tumor assessment for use in first-line trials in 
ovarian cancer [JNCI 92:1534-1535, 2000]. 
Cytology, Histology 
These techniques can be used to differentiate between partial 
responses (PR) and complete responses (CR) in rare cases (e.g., 

ECOG-ACRIN 
E7208 
Cancer Research Group 
Version Date: March 22, 2016 
54 
residual lesions in tumor types, such as germ cell tumors, where 
known residual benign tumors can remain). 
The cytological confirmation of the neoplastic origin of any effusion 
that appears or worsens during treatment when the measurable tumor 
has met criteria for response or stable disease is mandatory to 
differentiate between response or stable disease (an effusion may be 
a side effect of the treatment) and progressive disease. 
FDG-PET 
FDG-PET may not be used as a response assessment in this study. 
6.1.4 
Response Criteria 
6.1.4.1 
Evaluation of Target Lesions 
Complete Response (CR) 
Disappearance of all target lesions. Any pathological lymph 
nodes (whether target or non-target) must have reduction 
in short axis to < 10 mm. 
Partial Response (PR) 
At least a 30% decrease in the sum of the diameters of 
target lesions, taking as reference the baseline sum 
diameters. 
Progressive Disease (PD) 
At least a 20% increase in the sum of the diameters of 
target lesions, taking as reference the smallest sum on 
study (this includes the baseline sum if that is the smallest 
on study).  In addition to the relative increase of 20%, the 
sum must also demonstrate an absolute increase of at 
least 5 mm.  (Note:  the appearance of one or more new 
lesions is also considered progression, See Section 
6.1.4.3). 
Stable Disease (SD) 
Neither sufficient shrinkage to qualify for PR nor sufficient 
increase to qualify for PD, taking as reference the smallest 
sum diameters while on study. (Note: a change of 20% or 
less that does not increase the sum of the diameters by 5 
mm or more is coded as stable disease) 
To be assigned a status of stable disease, measurements 
must have met the stable disease criteria at least once 
after study entry at a minimum interval of eight weeks. 
6.1.4.2 
Evaluation of Non-Target Lesions 
Complete Response (CR) 
Disappearance of all non-target lesions and normalization 
of tumor marker level. All lymph nodes must be non-
pathological in size (< 10 mm short axis) 

ECOG-ACRIN 
E7208 
Cancer Research Group 
Version Date: March 22, 2016 
55 
NOTE: 
If tumor markers are initially above the upper 
normal limit, they must normalize for a patient to 
be considered in complete clinical response. 
Non-CR/Non-PD 
Persistence of one or more non-target lesion(s) and/or 
maintenance of tumor marker level above the normal 
limits. 
Progressive Disease (PD) 
Appearance of one or more new lesions and/or 
unequivocal progression of existing non-target lesions (see 
Section 6.1.4.3). Unequivocal progression should not 
normally trump target lesion status.  It must be 
representative of overall disease status change, not a 
single lesion increase. 
When the patient also has measurable disease, there must 
be an overall level of substantial worsening in non-target 
disease such that, even in the presence of SD or PR in 
target disease, the overall tumor burden has increased 
sufficiently to merit discontinuation of therapy. A modest 
“increase” in the size of one or more on-target lesions is 
usually not sufficient to qualify for unequivocal progression 
status. The designation of overall progression solely on the 
basis of change in non-target disease in the face of SD or 
PR of target disease will therefore be extremely rare. 
When the patient only has non-measurable disease, the 
increase in overall disease burden should be comparable 
in magnitude to the increase that would be required to 
declare PD for measurable disease: i.e., an increase in 
tumor burden from “trace” to “large”, an increase in nodal 
disease from “localized” to “widespread”, or an increase 
sufficient to require a change in therapy. 
Although a clear progression of “non-target” lesions only is 
exceptional, the opinion of the treating physician should 
prevail in such circumstances, and the progression status 
should be confirmed at a later time by the review panel (or 
Principal Investigator). 
6.1.4.3 
Evaluation of New Lesions 
The appearance of new lesions constitutes Progressive 
Disease (PD). 
6.1.4.4 
Evaluation of Best Overall Response 
The best overall response is the best response recorded 
from the start of the treatment until disease 
progression/recurrence or non-protocol therapy (taking as 
reference for progressive disease the smallest 
measurements recorded since the treatment started).  The 
patient's best response assignment will depend on the

*See RECIST 1.1 manuscript for further details on what is evidence of a new lesion. 
**In exceptional circumstances, unequivocal progression in non-target lesions  may 
be accepted as disease progression. 
NOTE: Patients with a global deterioration of health status requiring discontinuation 
of treatment without objective evidence of disease progression at that time 
should be reported as “symptomatic deterioration.” Every effort should be 
made to document the objective progression even after discontinuation of 
treatment. 
Duration of Response 
Duration of Overall Response 
The duration of overall response is measured from the time 
measurement criteria are met for CR or PR (whichever is 
first recorded) until the first date that recurrent or 
progressive disease is objectively documented (taking as 
reference for progressive disease the smallest 
measurements recorded since the treatment started). 
The duration of overall CR is measured from the time 
measurement criteria are first met for CR until the first date 
that progressive disease is objectively documented. 
Duration of Stable Disease 
Stable disease is measured from the start of the treatment 
until the criteria for progression are met, taking as 
reference the smallest measurements recorded since the 
treatment started, including the baseline measurements.  
To be assigned a status of stable disease, measurements 
must have met the stable disease criteria at least once 
after study entry at a minimum interval of eight weeks.

Drug Formulation and Procurement 
8.1 
Irinotecan (CPT-11) (NSC-616348) 
Other Names  Irinotecan hydrochloride trihydrate [CPT- 1 1, (4S)-4, 1 1- diethyl-
4-hydroxy-9- [(4-piperidinopiperidino) carbonyloxy] -IHpyroano [3',4':6, 7l 
indolzino [1 ,2-bl quino line-3, 14(4H, l2H)dione hydrochloride trihydrate] is a 
topoisomerase I inhibitor.  
8.1.1 
Classification  
Topoisomerase I inhibitor  
8.1.2 
Toxicology 
Human Toxicity: Virtually all Phase I and II studies of irinotecan have 
reported neutropenia and diarrhea as the dose-limiting toxicities. It is 
expected that these toxicities will also be encountered in this trial. 
Other Grade 2-3 toxicities seen include nausea and vomiting, 
anorexia, abdominal cramping, cumulative asthenia, 
thrombocytopenia, renal insufficiency, increase in transaminase level 
and hair loss. Sporadic cases of pulmonary toxicity, manifested as 
shortness of breath and nonproductive cough, have also been 
reported. 
8.1.3 
Mode of Action 
Causes single stranded DNA breakage by inhibition of the 
intranuclear enzyme toposisomerase-1.  Leads to apoptotic cell death 
via defects in DNA repair. 
8.1.4 
Pharmacology 
Pharmacokinetics: Several studies describing the pharmacokinetic 
characteristics of irinotecan (CPT-11) and its active metabolite, SN-
38, when administered alone or in combination with other agents 
(including cisplatin) in patients with small cell or non-small cell lung 
cancer have been reported in published literature.  CPT- 11 is 
converted by carboxylesterases to its more active metabolite, SN-38. 
In vitro, SN-38 is 250 to 1,000 fold more potent than CPT-11 in the 
inhibition of topoisomerase I activity.  A reversible, pH-dependent 
hydrolysis converts the closed lactone E ring form of both CPT-11 and 
SN-38 to the open, carboxylate form of each compound. Only the 
closed ring (lactone) forms of CPT-11 and SN-38 are effective 
topoisomerase I inhibitors. The mean terminal half-life of SN-38 in 
plasma is slightly longer than that for CPT-11; 11.5 ± 3.8 hours versus 
6.3 ± 2.2 hours for the lactone forms. Peak plasma concentrations for 
CPT-11 occur at the end of the infusion. The time to peak for SN-38 is 
highly inter-patient dependent occurring at variable times points 30 to 
90 minutes after the end of infusion. Murine studies suggest that the 
liver may concentrate, convert CPT-11 to SN-38, and eliminate both 
compounds as well as the glucuronide conjugate of SN-38 (SN-38G) 
via biliary secretion. In rats, 55% of radiolabeled CPT-11 was 
excreted unchanged in the bile within 24 hours, while 21.7% was 
transformed to SN-38. It recently was demonstrated that plasma 

ECOG-ACRIN 
E7208 
Cancer Research Group 
Version Date: March 22, 2016 
60 
concentrations of SN-38G in patients occur 0.5 to 3 hr after the SN38 
peak and plasma levels generally exceeded that of SN-38.  Overall, 
73% of the radioactivity could be recovered from the feces of rats and 
25% from the urine. Bile concentrations of CPT-11 were 10 to 60 fold 
higher than plasma concentrations in one patient during the first 6 
hours following administration, while bile concentrations of SN-38 
were 2 to 9 fold higher.  Renal clearance has not been reported to be 
a major route of elimination for these compounds in humans. 
8.1.5

Nursing/Patient Implications  
Premedicate with antiemetics in anticipation of mild to moderate 
nausea and vomiting.  When used in combination with 5-fluroruracil 
and leucovorin the nausea and vomiting will likely be worse. 
Fatalities have been reported with thromboembolic events and 
neutropenic sepsis in patients receiving 5-fluorouracil, leucovorin and 
irinotecan. 
Monitor for diarrhea. Diarrhea occurring within one hour of irinotecan 
has been treated with atropine 0.25 to 1mg IV or SC. Loperamide has 
been effective in treating later diarrhea and the patient should be 
instructed on its immediate use at the first loose stool following the 
irinotecan (see Section 5.5.2). 
Monitor CBC, platelets, and liver function tests. 
Dose modifications per the protocol or the package insert should be 
followed for hematologic and gastrointestinal toxicity.

IMC-C225, Erbitux®, NSC-714692 
8.2.2 
Classification 
Anti-EGF Receptor antibody 
8.2.3 
Mode of Action  
Cetuximab, a chimerized antibody of the IgG1 subclass, was originally 
derived from a mouse myeloma cell line. Cetuximab was genetically 
engineered by cloning the heavy and light chains of cetuximab and 
adapting them for expression together with the constant regions of the 
human kappa light chain and human gamma 1 heavy chain. The 
chimerization resulted in an antibody with binding affinity to epidermal

62 
growth factor receptors (EGFR) greater than the natural ligand 
epidermal growth factor (EGF). Cetuximab blocks binding of EGF and 
transforming growth factor alpha (TGFα) to EGFR and inhibits ligand-
induced activation of this tyrosine kinase receptor. Cetuximab also 
stimulates EGFR internalization, effectively removing the receptor 
from the cell surface for interaction with ligand. 
8.2.4 
Storage and Stability 
Cetuximab is an anti-EGFR human-to-murine chimeric antibody. 
Cetuximab is expressed in SP2/0 myeloma cell line, grown in large 
scale cell culture bioreactors and purified to a high level purity using 
several purification steps including protein A chromatography, ion 
exchange chromatography, low pH treatment and nanofiltration. 
Cetuximab is not known to be a vesicant. 
Store vials under refrigeration at 2°C to 8°C (36°F to 46°F). DO NOT 
FREEZE. Increased particulate formation may occur at temperatures 
at or below 0°C. This product contains no preservatives. Preparations 
of cetuximab in infusion containers are chemically and physically 
stable for up to 12 hours at 2°C to 8°C (36°F to 46°F) and up to 8 
hours at controlled room temperature (20°C to 25°C; 68°F to 77°F). 
Discard any remaining solution in the infusion container after 8 hours 
at controlled room temperature or after 12 hours at 2°C to 8°C.  
Discard any unused portion of the vial.

Cetuximab can be administered via infusion pump. 
8.2.7 
Route of Administration  
Administration of Cetuximab: In an effort to prevent a hypersensitivity 
reaction, all patients should be premedicated with diphenhydramine 
hydrochloride 50 mg (or an equivalent antihistamine) by IV given 30-
60 minutes prior to the first dose of cetuximab.  Premedication may be 
administered prior to subsequent doses, but at the Investigator’s 
discretion, the dose of diphenhydramine (or a similar agent) may be 
reduced. 
The initial dose of cetuximab is 400 mg/m2 or 500 mg/m2 as assigned 
intravenously administered over AT LEAST 120 minutes, followed by 
ONE HOUR infusions every 2 weeks. Cetuximab should not be 
given at a rate faster than 5 ml/min for the first dose. Patients 
must be continuously observed during the infusion for signs of 
anaphylaxis. 
Patients will be closely monitored for treatment-related adverse 
events, especially hypersensitivity reactions, during the infusion and 
the post-infusion observation hour. For the duration that patients are 
on study therapy, adverse event monitoring will be done continuously. 
Patients will be evaluated for adverse events at each visit and are to 
be instructed to call their physician to report any clinically significant 
adverse events between visits. 
Severe infusion reactions occurred with the administration of 
cetuximab in approximately 3% (17/633) of patients, rarely with fatal 
outcome (< 1 in 1,000). Approximately 90% of severe infusion 
reactions were associated with the first infusion of cetuximab despite 
the use of prophylactic antihistamines. These reactions were 
characterized by the rapid onset of airway obstruction 
(bronchospasm, stridor, hoarseness), urticaria and/or hypotension. 
Caution must be exercised with every cetuximab infusion, as there 
were patients who experienced their first severe infusion reaction 
during later infusions. 
Cetuximab can be administered via infusion pump or syringe pump. 
Infusion Pump: 
1. Draw up the volume of a vial using a sterile syringe attached to an 
appropriate needle (a vented spike or other appropriate transfer 
device may be used). 
2. Fill cetuximab into a sterile evacuated container or bag such as 
glass containers, polyolefin bags (e.g., Baxter Intravia), ethylene 
vinyl acetate bags (e.g., Baxter Clintec), DEHP plasticized PVC 
bags (e.g., Abbott Lifecare), or PVC bags. 
3. Repeat procedure until the calculated volume has been put in to 
the container.  Use a new needle for each vial. 
4. Administer through a low protein binding 0.22-micrometer in-line 
filter (placed as proximal to the patient as practical).

5. Affix the infusion line and prime it with cetuximab before starting 
the infusion. 
6. Maximum infusion rate should not exceed 5 mL/min. 
7. Use 0.9% saline solution to flush line at the end of infusion. 
Cetuximab should be piggybacked to the patient’s infusion line.  
Following the cetuximab infusion, a 1-hour observation period is 
recommended.

8.2.10 
Anticipated Adverse Events 
Except where indicated, the data described below reflect exposure to 
cetuximab in 633 patients with advanced metastatic colorectal cancer.  
Cetuximab was studied in combination with irinotecan (n=354) or as 
monotherapy (n=279). Patients receiving cetuximab plus irinotecan 
received a median of 12 doses (with 88/354 [25%] treated for over 6 
months), and patients receiving cetuximab monotherapy received a 
median of 7 doses (with 26/279 [9%] treated for over 6 months).  The 
population had a median age of 59 and was 60% male and 91% 
Caucasian.  The range of dosing for patients receiving cetuximab plus 
irinotecan was 1-84 infusions, and the range of dosing for patients 
receiving cetuximab monotherapy was 1-63 infusions. 
The most serious adverse reactions associated with cetuximab 
were:   
Infusion reaction (3%); 
Dermatologic toxicity (1%); 
Interstitial lung disease (0.5%); 
Fever (5%); 
Sepsis (3%); 
Kidney failure (2%); 
Pulmonary embolus (1%); 
Dehydration (5%) in patients receiving cetuximab plus irinotecan, 2% 
in patients receiving cetuximab monotherapy; 
Diarrhea (6%) in patients receiving cetuximab plus irinotecan, 0% in 
patients receiving cetuximab monotherapy. 
Thirty-seven (10%) patients receiving cetuximab plus irinotecan and 
14 (5%) patients receiving cetuximab monotherapy discontinued 
treatment primarily because of adverse events.

The most common adverse events seen in 354 patients receiving 
cetuximab plus irinotecan were acneiform rash (88%), 
asthenia/malaise (73%), diarrhea (72%), nausea (55%), abdominal 
pain (45%), and vomiting (41%).  
The most common adverse events seen in 279 patients receiving 
ERBITUX monotherapy were acneiform rash (90%), asthenia/malaise 
(49%), fever (33%), nausea (29%), constipation (28%), and diarrhea 
(28%).  
Because clinical trials are conducted under widely varying conditions, 
adverse reaction rates observed in the clinical trials of a drug cannot 
be directly compared to rates in the clinical trials of another drug and 
may not reflect the rates observed in practice. The adverse reaction 
information from clinical trials does, however, provide a basis for 
identifying the adverse events that appear to be related to drug use 
and for approximating rates. 
Data in patients with advanced colorectal carcinoma in the following 
table are based on the experience of 354 patients treated with 
cetuximab plus irinotecan and 279 patients treated with cetuximab 
monotherapy. [ERBITUX TM (Cetuximab) package insert. ImClone 
Systems Incorporated and Bristol-Myers Squibb Company. 2004 ER-
B00001-02-04]. 
NOTE: There have been reports of hypomagnesemia during 
cetuximab therapy. The majority of the cases have been 
documented as decreased serum magnesium levels 
observed in routine electrolyte monitoring, and not as a result 
of clinical symptoms.

Statistical Considerations 
9.1 
Revised Statistical Design - Arms A (IC) and C (mICR) 
Safety Monitoring 
The revised investigational regimen (that is, Arm C (mICR), a revision of the 
previous investigational Arm B) will be examined among the first 16 patients 
enrolled to Arm C post the re-activation of the randomized trial. Randomization 
will commence to Arms A and C and for purposes of adverse event evaluation, 
close monitoring of the study will occur until 16 patients have been enrolled to 
Arm C and followed through 2 cycles of therapy. During this safety evaluation 
period all patients will be followed closely with monthly conference calls of the 
study team and independent toxicity monitor to review all real-time CTEP-AERS 
reports and any case report form reported treatment-related adverse events. At 
the time of suspension of this study prior to reactivation, the accrual rate was 
about 3-4 patients per month. Given this expected recruitment pattern upon 
initially re-opening the study, it appears reasonable to have calls on a monthly 
basis. Once fully reactivated, the accrual rate should be 10 patients per month. If 
the accrual pattern is substantially higher during the first few months after 
reactivation, the study team will convene calls every two weeks. 
The toxic death rate on Arm B (ICR) prior to study suspension was 2/16 patients 
or 12.5%. With 16 patients on Arm C (mICR) evaluated under the new regimen 
the probability of observing 1 or more toxic deaths is 81.5% if the true toxic death 
rate is 10% and 88.2% under a true toxic death rate of 12.5%. No toxic deaths 
were observed in Arm A prior to suspension among 17 treated patients. Under 
the revised design with 16 patients evaluated on Arm C (mICR) the probability of 
observing one or more toxic deaths under a true toxic death rate of 0.77% is 
11.6%. If one or more toxic deaths occur at any point during the 16 patient 
evaluation of Arm C, the study will close to accrual and the regimen will be 
abandoned. 
The safety evaluation will also closely assess all treatment-related toxicities other 
than those of grade 5 with a particular emphasis on evaluating grade 3 and 4 
events. Prior to suspension the grade 3 or higher treatment-related adverse 
event rate on Arm A was 16.7%. With 16 patients on Arm C there is 81% power 
to detect a true grade 3 or higher toxicity rate of 39% (versus a null of 16.7%) 
and 90% power to detect a true rate of 44% using a one-sided exact binomial 
test at the 11% significance level (evaluating Arm C separately as the power for 
the two-group comparison is limited). The observed grade 3 or higher toxicity rate 
on Arm B was 87.5%. If the grade 3 or higher toxicity test is significant after 16 
patients on Arm C, the study will suspend accrual and the feasibility of the 
revised regimen will be evaluated by the study team and independent toxicity 
monitor, including a detailed review of all grade 3 or higher treatment related 
events. In addition to the above safety monitoring plan, the study will suspend 
upon the report of any colonic perforation event, regardless of treatment 
attribution or grade. A detailed review of the circumstances surrounding the event 
will be conducted and, in the case of the event occurring on Arm C, the feasibility 
of the revised regimen will be evaluated by the study team and toxicity monitor. 
The colonic perforation rate on Arm B (ICR) prior to study suspension was 2/16 
patients or 12.5%. With 16 patients on Arm C (mICR) evaluated under the new

regimen the probability of observing 1 or more colonic perforations is 81.5% if the 
true rate is 10% and 88.2% under a rate of 12.5%. No toxic deaths were 
observed in Arm A prior to suspension among 17 treated patients. 
In addition, the evaluation of 16 patients randomized to Arm C will allow 
estimation of any given toxicity with a 90% confidence interval that is no wider 
than 44.3 percentage points and there is 56.0% probability of observing any 
given event (1 or more out of 16 patients) with a true frequency of 5% and 81.5% 
probability observing 1 or more events with true frequency of 10%. 
Primary Efficacy Design 
Patients will be randomized equally between the two treatment arms A (IC) and 
C (mICR) with stratification based on performance status (0 vs. 1), 
discontinuation of oxaliplatin before disease progression (Yes vs. No), and time 
frame of progression (within 6 months of last treatment vs. > 6 months since last 
treatment). Patients previously randomized to arms A and B before the redesign 
of the experimental regimen will not be part of the formal efficacy evaluation and 
will be reported separately. 
With 48 eligible patients per arm followed for progression-free survival (disease 
progression or death without evidence of progression), this study has over 85% 
power to detect a difference of 4.5 months median PFS in the control arm A 
(40% PFS at 6 months assuming exponential failure) versus 7.65 months median 
PFS (58% PFS at 6 months) in the experimental arm (Arm C) using a one-sided 
stratified log rank test conducted with 15% type 1 error. The study will require 
approximately 10 months of accrual at 10 patients per month and 6 additional 
months of follow-up to achieve the events required (67 PFS events) to provide at 
least 85% power for the stated alternative of a 48% increase in median PFS. 
Response, overall survival, and toxicity are secondary endpoints and will be 
reported at the time of primary PFS analysis.  With 48 eligible patients per arm, 
the width of any 90% confidence interval on a binomial proportion will be no 
wider than 26 percentage points.  In addition, the probability of observing a rare 
(2% probability) toxicity in either arm is greater than 62% at full accrual. Allowing 
for roughly 5% ineligibility and including the 35 patients who were previously 
randomized to Arms A and B of the study prior to its redesign, this study will 
require a total of 135 patients and 100 patients will be accrued to the revised 
study (Arm A versus Arm C). 
This study will be monitored by the ECOG-ACRIN Data Safety Monitoring 
Committee (DSMC) for early stopping due to efficacy and futility. One interim 
stratified log rank test for efficacy will be performed at 60% PFS information (40 
PFS events), expected to occur roughly at the time accrual completes and six 
months before full information is achieved. Type I error control will be 
accomplished using an O'Brien-Fleming type boundary, with Lan-Demets use 
function methodology to adjust the boundary for the exact information time 
achieved at the interim analysis. If the study is positive, the DSMC may 
recommend early reporting; there is at least 55% probability of rejecting the null 
at the interim analysis if the alternative hypothesis is true. At the interim analysis 
time, the PFS hazard ratio will also be computed from a stratified proportional 
hazards regression model. If the HR exceeds 1 (that is, evidence that PFS is 
worse in the experimental Arm C), the DSMC may recommend abandoning the 
regimen and early reporting of negative results. The effect of the interim analysis

74 
on the operating characteristics of the trial is fairly small (less than 1% absolute 
effect on significance level and power). 
Additional Safety Monitoring 
In addition to the safety monitoring that will occur in the first 16 patients 
randomized to Arm C (described above), interim analyses of toxicity are 
performed twice yearly for all ECOG-ACRIN studies. Reports of these analyses 
are sent to the ECOG-ACRIN Principal Investigator or Senior Investigator at the 
participating institutions. Expedited reporting of certain adverse events is 
required, as described in Section 5.2 and ECOG-ACRIN Operations Office – 
Boston’s real-time monitoring of events through CTEP-AERS report notifications 
will be in place for this trial. This system provides monthly notifications to the 
study chair, study statistician and independent toxicity monitor of certain 
reportable grade 4 or higher events and all grade 5 events. 
9.2 
Original Statistical Design (Arms A and B) 
Patients will be randomized equally between the two treatment arms with 
stratification based on performance status (0 vs. 1), discontinuation of oxaliplatin 
before disease progression (Yes vs. No), and time frame of progression (within 6 
months of last treatment vs. > 6 months since last treatment). With 70 eligible 
patients per arm followed for progression-free survival (disease progression or 
death without evidence of progression), this study has 90% power to detect a 
difference of 4.5 months median PFS in the control arm (40% PFS at 6 months 
assuming exponential failure) versus 7.65 months median PFS (58% PFS at 6 
months) in the experimental arm using a one-sided log rank test conducted with 
10% type 1 error.  The study will require approximately 7 months of accrual at 20 
patients per month and 7 additional months of follow-up to achieve the events 
required (100 PFS events) to provide 90% power for the stated alternative of a 
70% increase in median PFS.  Response, overall survival, and toxicity are 
secondary endpoints and will be reported at the time of primary PFS analysis.  
With 70 eligible patients per arm, the width of any 90% confidence interval on a 
binomial proportion will be no wider than 21 percentage points.  In addition, the 
probability of observing a rare (1% probability) toxicity in either arm is greater 
than 50% at full accrual. Allowing for 5% ineligibility, this study will require a total 
of 147 patients. 
Safety Monitoring 
Interim analyses of toxicity are performed twice yearly for all ECOG-ACRIN 
studies. Reports of these analyses are sent to the ECOG-ACRIN Principal 
Investigator or Senior Investigator at the participating institutions. Expedited 
reporting of certain adverse events is required, as described in Section 5.2 and 
ECOG-ACRIN Operations Office – Boston’s real-time monitoring of events 
through CTEP-AERS report notifications will be in place for this trial. This system 
provides monthly notifications to the study chair, study statistician and 
independent toxicity monitor of certain reportable grade 4 or higher events and all 
grade 5 events.  
In addition to ECOG-ACRIN’s routine semi-annual reporting of case report form 
toxicities through interim study reports and real-time monitoring of adverse 
events through CTEP-AERS, this study will include a detailed toxicity review of 
both treatment arms after 20 patients on each arm have been treated with at

least two cycles of therapy. After 20 patients have been randomized per arm, the 
study will suspend accrual. After the first 20 patients have been treated with at 
least 2 cycles of therapy, there will be a formal toxicity review once all cycle 2 
treatment forms and associated adverse event forms through this treatment 
period have been submitted to the ECOG-ACRIN Operations Office – Boston. 
The study statistician will prepare a report of all case report form and CTEP-
AERS reportable events for review by the study team and independent toxicity 
monitor. The study will remain suspended until the review is complete.  
With 20 patients per arm, there is greater than 55% probability of observing one 
or more rare (true probability of 4%) toxicities on either arm and greater than 
87% chance of observing one or more toxicities with true rate in excess of 10%. 
If 4 or more patients experience grade 4 or worse treatment-related events in an 
arm, consideration will be given to closing the trial or modifying the treatment 
regimens. Under this monitoring rule, there is less than 2% probability of meeting 
the monitoring boundary if the true grade 4 or higher toxicity probability is 5% but 
89% chance of meeting the boundary if the true probability is 30%. For other true 
grade 4 probabilities of 10%, 20% and 25%, the corresponding probabilities of 
reaching the boundary are 13%, 59% and 77%, respectively. Toxicity analyses 
will be conducted separately in each arm.  In addition to grade 4 toxicities, 
differences between the treatment arms with respect to all grade toxicities, grade 
3-4 toxicities, and non-hematologic toxicities will be assessed. If it is deemed 
necessary by the study team/independent toxicity monitors, an additional interim 
safely assessment will be conducted. 
Grade 5 events will also be separately monitored and reported. The recently 
reported EPIC trial (Sobrero et al., 2008) observed a toxic death rate of 0.77% in 
the cetuximab plus irinotecan arm (5 deaths among 650 patients). Taking 0.77% 
as the null toxic death rate for either arm in this trial and 5% or higher as an 
unacceptable alternative toxic death rate, we will consider modifying or closing 
the trial if in either arm 1 or more treatment-related toxic deaths are observed 
among the first 20 treated patients. Under the null hypothesis there is a 14% 
probability of observing one or more grade 5 events in the first 20 patients and 
64% probability under the alternative. If the true grade 5 event rate is as high as 
10%, there is 88% probability of observing 1 or more toxic deaths in the first 20 
patients treated on an arm. In addition to the toxicity analysis at suspension, 
grade 5 events will be continuously monitored, reported and reviewed as 
indicated above. At full accrual, the probability of observing 2 or more grade 5 
events out of 70 patients in an arm is 10% under the null hypothesis and 87% 
under the alternative hypothesis. 
9.3 
Study Monitoring 
This study will be monitored by the ECOG-ACRIN Data Safety Monitoring 
Committee (DSMC). The DSMC meets twice each year. For each meeting, all 
monitored studies are reviewed for safety and progress toward completion. When 
appropriate, the DSMC will also review interim analyses of outcome data. Copies 
of the toxicity reports prepared for the DSMC meetings are included in the study 
reports prepared for the ECOG-ACRIN group meeting (except that for double 
blind studies, the DSMC may review unblinded toxicity data, while only pooled or 
blinded data will be made public). These group meeting reports are made 
available to the local investigators, who may provide them to their IRBs. Only the 
study statistician and the DSMC members will have access to interim analyses of

outcome data. Prior to completion of this study, any use of outcome data will 
require approval of the DSMC. Any DSMC recommendations for changes to this 
study will be circulated to the local investigators in the form of addenda to this 
protocol document. A complete copy of the ECOG-ACRIN DSMC Policy can be 
obtained from the ECOG-ACRIN Operations Office – Boston.
