Randomized Phase II Study of Irinotecan and Cetuximab With or Without Vemurafenib in BRAF Mutant Metastatic Colorectal Cancer
This randomized phase II trial studies how well irinotecan hydrochloride and cetuximab with
or without vemurafenib works in treating patients with colorectal cancer that has spread to
nearby tissue or lymph nodes, that has spread to other places in the body, or cannot be
removed by surgery. Irinotecan hydrochloride and vemurafenib may stop the growth of tumor
cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as
cetuximab, may block the ability of tumor cells to grow and spread. It is not yet known
whether irinotecan hydrochloride and cetuximab are more effective with or without vemurafenib
in treating colorectal cancer.

PRIMARY OBJECTIVES:
I. To evaluate the progression-free survival (PFS) of v-raf murine sarcoma viral oncogene
homolog B (BRAF) mutant metastatic colorectal cancer patients treated with irinotecan
(irinotecan hydrochloride), cetuximab, and vemurafenib, compared to a control arm of
irinotecan and cetuximab.
SECONDARY OBJECTIVES:
I. To evaluate the frequency and severity of toxicity associated with each of the treatment
arms in this patient population.
TERTIARY OBJECTIVES:
I. To evaluate overall survival (OS) in treatment Arms 1 and 2. II. To evaluate the overall
response rate (ORR), including confirmed and unconfirmed, complete and partial response, in
treatment Arms 1 and 2 in the subset of patients with measurable disease.
III. To estimate rates of OS, ORR, and PFS in patients who register to Arm 3 after disease
progression on Arm 1.
IV. To evaluate low-frequency Kirsten rat sarcoma viral oncogene homolog (KRAS) or
neuroblastoma RAS viral (v-ras) oncogene homolog (NRAS) mutations as detected by high-depth
sequencing as predictive biomarkers of efficacy.
V. To evaluate phosphatidylinositol-4,5-bisphosphate 3-kinase, catalytic subunit alpha
(PIK3CA) pathway activation through PIK3CA mutations or phosphatase and tensin homolog (PTEN)
protein loss as a predictive biomarker of innate resistance to this regimen.
VI. To evaluate gene expression signatures from screened patients with v-raf murine sarcoma
viral oncogene homolog B wild type (BRAFWT) and BRAFV600E tumors.
VII. To provide validation of BRAF immunohistochemistry (IHC) using complementary sequencing
methodology from screened patients with BRAFWT and BRAFV600E tumors.
VIII. To confirm the estimated sensitivity of detectable BRAF V600E circulating cell-free
deoxyribonucleic acid (DNA) as a non-invasive biomarker for BRAF V600E mutation as detected
by IHC in the primary tumor.
IX. To correlate radiographic tumor response with change in quantification of BRAFV600E
alleles in circulating cell-free DNA.
X. To monitor for known mechanism of acquired resistance to epidermal growth factor receptor
(EGFR) inhibition in circulating cell-free DNA (KRAS, NRAS mutations).
OUTLINE: Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients receive cetuximab intravenously (IV) and irinotecan hydrochloride IV on days
1 and 14. Courses repeat every 28 days in the absence of disease progression or unacceptable
toxicity. Patients with disease progression may cross over to Arm II.
ARM II: Patients receive cetuximab and irinotecan hydrochloride as in Arm I and vemurafenib
orally (PO) twice daily (BID) on days 1-28. Courses repeat every 28 days in the absence of
disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 2-6 months for 3 years.

to, active bleeding diathesis, uncontrolled infection/disorders, nonmalignant medical
illnesses that are uncontrolled or whose control may be jeopardized by the treatment
with the study therapy, or psychiatric illness/social situations which would limit
compliance with study requirements
- Patients must be able to swallow pill/tablet and have no refractory nausea, vomiting,
malabsorption, external biliary shunt, or significant small bowel resection that would
preclude adequate absorption
- Patients must not be pregnant or nursing; women/men of reproductive potential must
have agreed to use an effective contraceptive method while on study and for 30 days
after study treatment; a woman is considered to be of "reproductive potential" if she
has had menses at any time in the preceding 12 consecutive months; in addition to
routine contraceptive methods, "effective contraception" also includes heterosexual
celibacy and surgery intended to prevent pregnancy (or with a side-effect of pregnancy
prevention) defined as a hysterectomy, bilateral oophorectomy or bilateral tubal
ligation; however, if at any point a previously celibate patient chooses to become
heterosexually active during the time period for use of contraceptive measures, he/she
is responsible for beginning contraceptive measures
