Phase II Trial of Weekly Erlotinib Dosing to Reduce Duodenal Polyp Burden Associated With Familial Adenomatous Polyposis

This phase II trial studies the side effects of erlotinib hydrochloride and how well it works
in reducing duodenal polyp burden in patients with familial adenomatous polyposis at risk of
developing colon cancer. Erlotinib hydrochloride may stop the growth of tumor cells by
blocking some of the enzymes needed for cell growth.

PRIMARY OBJECTIVES:

I. To assess the mean percent change in duodenal polyp burden (sum of diameters from all
polyps) from baseline to 6 months post-intervention for familial adenomatous polyposis (FAP)
subjects receiving weekly erlotinib hydrochloride (erlotinib).

II. To assess the grade 2/3 adverse event rate in this population and compare it to
historical data.

SECONDARY OBJECTIVES:

I. To evaluate all adverse events at least possibly attributed to weekly erlotinib.

II. To assess the absolute and percent change in duodenal polyp number from baseline to 6
months.

III. To assess the absolute and percent changes in lower gastrointestinal polyp burden and
number for the subset of participants with ileal pouch anal anastomosis (IPAA) or ileo-rectal
anastomosis with rectal stump.

IV. To assess the absolute and percent change in desmoid tumor size in participants who have
baseline and follow up computed tomography (CT)s performed as part of their standard of care.

V. Gene expression profiles in duodenal adenomas and uninvolved tissue will be compared
between baseline and endpoint samples using negative binomial statistics (DESeq2).

VI. Identify differentially expressed genes between duodenal polyps and uninvolved tissue at
endpoint compared to baseline.

VII. Evaluate the effect of weekly erlotinib on EGFR and Wnt target gene expression in
duodenal adenomas.

VIII. Evaluate the effect of weekly erlotinib on immune response signaling in duodenal
adenomas and uninvolved tissue.

OUTLINE:

Patients receive erlotinib hydrochloride orally (PO) once weekly. Treatment continues for up
to 6 months in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days.

Inclusion Criteria:

- PRE-REGISTRATION INCLUSION

- Diagnosis of familial adenomatous polyposis (FAP) or attenuated familial adenomatous
polyposis (AFAP), defined as at least one of the following:

Act [CLIA] certified lab or research testing)

- Obligate carrier

- Clinical diagnosis of classic FAP with >= 100 colorectal adenomas status post
colectomy and a family history of FAP

criterion requires documented review and agreement from either the study chair or
the Cancer Prevention Network (CPN) lead investigator

days prior to initiation of and during intervention; exception: use of =< 81 mg daily
or =< 650 mg weekly aspirin is allowed

- Hemoglobin >= 11.5 g/dL

- Total bilirubin =< 1.5 x institutional upper limit of normal (ULN)

- Alkaline phosphatase =< 1.5 x institutional upper limit of normal (ULN)

- Aspartate aminotransferase (AST)/serum glutamic-oxaloacetic transaminase (SGOT) =< 2 x
institutional upper limit of normal (ULN)

insignificant

- Spigelman 2‐3

- Not pregnant or breast feeding; women of child-bearing potential and men must agree to
use adequate contraception (hormonal or barrier method of birth control; abstinence)
prior to study entry and for the duration of study participation; should a woman
become pregnant or suspect she is pregnant while participating in this study, she
should inform her study physician immediately; breastfeeding should be discontinued if
the mother is treated with erlotinib

- Willing to use adequate contraception to avoid pregnancy or impregnation until 2 weeks
after discontinuing study agent

Exclusion Criteria:

- PRE-REGISTRATION EXCLUSION

- Any prior treatment with erlotinib or other agent whose primary mechanism of action is
known to inhibit EGFR

- History of allergic reactions attributed to compounds of similar chemical or biologic
composition to erlotinib

- Use of potent CYP3A4 inhibitors, including but not limited to ketoconazole,
atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir,
ritonavir, saquinavir, telithromycin, troleandomycin, voriconazole, and grapefruit or
grapefruit juice

- Use of potent CYP3A4 inducers, including but not limited to rifampicin, rifabutin,
rifapentine, phenytoin, carbamazepine, phenobarbital, and St. John's wort

- Use of any other investigational agents =< 12 weeks prior to pre-registration

- Uncontrolled intercurrent illness or recent surgical procedure that in the opinion of
the investigative team would limit compliance with study requirements, including, but
not limited to:

- Ongoing or active infection

- Symptomatic congestive heart failure

- Myocardial infarction =< 6 months prior to intervention

- Severely impaired lung function

- Nonmalignant medical illnesses that are uncontrolled or whose control may be
jeopardized by the treatment with study intervention

- Diagnosed liver disease, such as cirrhosis, chronic active hepatitis, or chronic
persistent hepatitis

- Unstable angina pectoris

- Cardiac arrhythmia

- Psychiatric illness/social situations

- History of invasive malignancy =< 3 years prior to pre-registration; exception:
adequately treated carcinoma of the cervix, carcinoma in situ, or basal or squamous
cell carcinomas of the skin

- Use of anticoagulation medications, including but not limited to coumadin, warfarin,
plavix

- History of any upper gastrointestinal (GI) surgery that does not permit access to or
evaluation of a 10 cm segment of the duodenum that includes the duodenal bulb, i.e.
whipple procedure or similar

- REGISTRATION EXCLUSION

- Histologically-confirmed high grade dysplasia (HGD), cancer, or polyp burden that is
not quantifiable

- Regular (>= 2 times per week) use of drugs that alter the pH of the gastrointestinal
tract (GI) tract, such as proton pump inhibitors (PPI) and antacids; exceptions:
individuals who use prescription PPIs and have approval from their primary health care

duration of the trial will be eligible

- Gastrointestinal bleeding; note that the presence of any symptoms (dyspnea, fatigue,
angina, weakness, malaise, melena, hematochezia, hematemesis, anemia, abdominal pain)
will require clinical assessment to rule out gastrointestinal bleeding
