Bevacizumab, Fluorouracil, Leucovorin Calcium, and Oxaliplatin Before Surgery in Treating Patients With Stage II-III Rectal Cancer

Stopped early · Phase 2

Conditions studied: Mucinous Adenocarcinoma of the Rectum, Signet Ring Adenocarcinoma of the Rectum, Stage IIA Rectal Cancer, Stage IIB Rectal Cancer, Stage IIC Rectal Cancer, Stage IIIA Rectal Cancer, Stage IIIB Rectal Cancer, Stage IIIC Rectal Cancer

In brief

This phase II trial studies how well bevacizumab, fluorouracil, leucovorin calcium, and oxaliplatin before surgery works in treating patients with stage II-III rectal cancer. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Drugs used in chemotherapy, such as fluorouracil, leucovorin calcium, and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving bevacizumab together with fluorouracil, leucovorin calcium, and oxaliplatin may be an effective treatment for rectal cancer.

You may qualify if…

Histologically confirmed adenocarcinoma of the rectum in patients with no prior therapy who are candidate for surgical resection
Tumor lesion is 5-15 cm from anal verge
cT2 N+ or cT3-T4 N0 or N+ as assessed by endorectal ultrasound scan (US)
No evidence of distant metastatic disease
Signed informed consent prior to initiation of any study-specific procedure or treatment
Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
Able to comply with the protocol, including tissue sampling, imaging studies and surgical intervention
Life expectancy more than 12 weeks
Absolute neutrophil count >= 1500 per mm\^3
Platelet count >= 100,000 per mm\^3
Hemoglobin >= 9 g/dL (may be transfused to maintain or exceed this level)
Total bilirubin < 1.5 x upper limit of normal (ULN)
Aspartate aminotransferase and alanine aminotransferase < 2.5 x ULN
Calculated creatinine clearance according to Cockroft and Gault formula >= 50 mL/min
Urine for proteinuria should be < 2 +; patients discovered to have >= 2 + proteinuria on dipstick urinalysis at baseline should undergo a 24-hour urine collection and must demonstrate < 1 g of protein in 24 hours
International normalized ratio =< 1.5 and activated prothrombin time =< 1.5 x ULN within 7 days prior to enrollment; the use of full-dose oral or parenteral anticoagulants is permitted as long as the international normalized ratio (INR) or activated partial thromboplastin time (aPTT) is within therapeutic limits (according to the medical standard of the enrolling institution) and the patient has been on a stable dose of anticoagulants for at least two weeks prior to the first study treatment
Female patients should not be pregnant or breast-feeding. Female patients, if not postmenopausal (< 12 months of amenorrhea) or surgically sterile, should agree to use effective, non-hormonal means of contraception (intrauterine contraceptive device, barrier method of contraception in conjunction with spermicidal jelly or surgically sterile) during the study and for a period of at least 6 months following the last administration of study drugs. Female patients with an intact uterus (unless amenorrheic for the last 24 months) must have a negative serum pregnancy test within 7 days prior to randomization into the study
Fertile male patients must agree to use a highly effective contraceptive method (i.e., with a failure rate of < 1 % per year, such as vasectomy, sexual abstinence, or female partner's use of hormonal implants or combined oral contraceptives) during the trial and for a period of at least 6 months after the last dose of study drug
Archival tumor tissue sample must be requested and available prior to study entry; a copy of the local pathology report must be submitted along with the specimens; patients without available archival tissue are excluded

You may not qualify if…

Radiotherapy to any site for any reason within 28 days prior to study entry
Treatment with any other investigational agent, or participation in another investigational drug trial within 28 days prior to randomization
Evidence of any other disease, neurological or metabolic dysfunction, physical examination finding, or laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of bevacizumab or puts the patient at high risk for treatment-related complications
Surgery (including open biopsy), significant traumatic injury within 28 days prior to randomization, minor surgery, including insertion of an indwelling catheter, within 24 hours prior to the first bevacizumab infusion is allowed

Inadequately controlled hypertension (blood pressure: systolic > 150 mmHg and/or diastolic > 100 mmHg)
Clinically significant (i.e., active) cardiovascular disease (e.g., cerebrovascular accident or myocardial infarction within 6 months prior to randomization), unstable angina, congestive heart failure (New York Heart Association Class >= II) or serious cardiac arrhythmia that is uncontrolled by medication or may interfere with administration of study treatment
