Phase I Study of Pre-operative Continuous 5-FU, and Sorafenib With External Radiation Therapy in Locally Advanced Rectal Adenocarcinoma
The main purpose of this study is to find the maximum tolerable dose of sorafenib when
administered along with another drug called 5-Fluorouracil (5-FU) and to find out more about
whether these drugs, along with radiation, can help people with rectal cancer when given
before surgery. 5-FU and radiation are both approved by the US Food and Drug Administration
(FDA) for use in people with rectal cancer.
The investigators will utilize a standard 3 + 3 phase I study design. In the phase I part of
the study, the investigators will attempt dose escalation of sorafenib in combination with
standard infusional 5-FU and external beam at standard doses. Clinical staging should be
done by endorectal ultrasound (ERUS) and/or pelvic magnetic resonance imaging (MRI) for T
and N stage; chest and abdomen computed tomography (CT) for staging of metastatic disease;
undergo sigmoidoscopy and/or colonoscopy done by crude odds ratios (CORS); biopsy is taken
for diagnosis and extra is sent for tissue bank. At the maximum tolerated dose (MTD) of
sorafenib we will expand the cohort to 6 more patients to further evaluate toxicity profile
and efficacy.

Participants' study regimen will include 5 ½ weeks of radiation. Radiation sessions will be
daily, Monday through Friday, except for holidays. 5-FU will be delivered at a dose of 225
mg/m² daily through a catheter in a large vein continuously until the last day of radiation.
In addition, sorafenib will be taken by mouth twice daily every day until the last day of
radiation. The dose of sorafenib participants may receive will be one of the following: 200
mg every other day, 200 mg daily, 400 mg daily, or 800 mg daily. Following completion of
this phase of the study, participants will receive no study drug or radiation for one month.
At 4 to 5 weeks after stopping study drug and radiation, participants will have another CT
scan or MRI to assess their cancer. About 6 to 8 weeks after the end of radiation,
participants will undergo surgery and every effort will be made to remove the tumor. The
surgery will occur just as it would if participants were not in the study, except that a
portion of their tumor obtained during surgery will be used for research biomarker testing
(as described in the consent form).
Approximately 6 -10 weeks after participants' surgery, when they have adequately healed,
they may receive additional chemotherapy at their study doctor's discretion.

Inclusion Criteria:
- Histologically confirmed adenocarcinoma of the rectum that begins within 12 cm of the
anal verge as determined by sigmoidoscopy and/or colonoscopy with no evidence of
distant metastasis
- Locally advanced rectal cancer determined by any of the following features: Fixed or
immobile tumor on physical exam and/or; T3 disease with invasion through the
muscularis propria as defined by transrectal ultrasound, CT or MRI; T4 disease with
invasion of adjacent structures such as pelvic sidewall, sacrum, pelvis, bladder
and/or prostate as determined appropriate imaging modalities such as ultrasound, CT
or MRI; Any T with + N on CT scan/MRI or transrectal ultrasound
- Eastern Cooperative Oncology Group (ECOG) Performance Status 0 or 1
- Adequate bone marrow, liver and renal function as assessed by the following:
Hemoglobin > 9.0 g/dl, Absolute neutrophil count (ANC) > 1,500/mm^3, Platelet count >
100,000/mm^3, Total bilirubin < 1.5 times upper limit of normal (ULN), alanine
aminotransferase (ALT) and aspartate aminotransferase (AST) < 2.5 times the ULN ( < 5
x ULN for patients with liver involvement), Creatinine < 1.5 times ULN
