Purpose:

This study, for patients who have Stage IIIC colorectal cancer and who underwent 5-fluorouracil/leucovorin with oxaliplatin (FOLFOX) chemotherapy after surgery, will test to see if regorafenib given after the completion of FOLFOX improves treatment, compared to standard of care (SOC), which is no further treatment.


Study summary:

Patients with Stage IIIC colon cancer have a 5-year survival rate of 28%. Stage III colon cancer indicates that lymph nodes are involved. Adjuvant FOLFOX only reduces the risk of recurrence of colorectal cancer by 40%, so almost 50% of patients still die from the disease. It is estimated that 50% of the patients relapse within 18 months. Because the prognosis of colorectal cancer is dependent on disease stage and because metastatic disease is incurable, the concept of adding regorafenib to adjuvant FOLFOX has been developed to allow patients with high-risk colorectal cancer the best chance of cure. It is proposed to treat high-risk colorectal patients (Stage IIIC [T4a, N2a, M0] or [T3-4a,N2b, M0], or [T4b, N1-N2, M0] per American Joint Committee on Cancer [AJCC] 7th ed.) selected from the iKnowMed (iKM) electronic health records database who have completed adjuvant FOLFOX. This feasibility study is to find the starting dose of regorafenib and estimates that at least 75% of the patients will be able to tolerate the full dose of regorafenib after receiving adjuvant FOLFOX. Patients will be randomly assigned to regorafenib or to SOC (no treatment). In order to test the best tolerated starting dose, the first 50 patients will receive regorafenib and will be randomized 1:1 to either 120 mg by mouth (PO) or 160 mg PO. If the 120 mg dose is well tolerated and the toxicities are not severe (Grade 2 or less) upon the completion of cycle 2, the dose will be increased to 160 mg starting with Cycle 3. Registration and randomization of patients will resume after the 26th then after the 50th patient completes 3 cycles of study treatment. The Data Safety Monitoring Board (DSMB) will meet after the 26th patient completes 3 cycles of treatment and the second meeting will take place after the 50th patient completes 3 cycles. If needed, a third DSMB meeting will be scheduled. The remaining 214 patients will be randomized 2:3 to the decided starting dose versus SOC. In addition, evaluating the Texture (spatial variations in pixel intensity) in computed tomography (CT) scans might help predict the risk of recurrence. Therefore, CT disks will be sent to Imaging Endpoints Core Lab, Scottsdale, AZ, where the TexRAD platform (a software algorithm) will be used for analysis.

(Subjects who are prophylactically treated with an agent such as warfarin or heparin will be allowed to participate provided that no prior evidence of underlying abnormality in coagulation parameters exists. Close monitoring of at least weekly evaluations will be performed until INR/PTT is stable based on a measurement that is pre-dose as defined by the local standard of care. - Platelet count ≥ 100,000 /mm3, hemoglobin (Hb) ≥ 9 g/dL, absolute neutrophil count (ANC) ≥ 1500/mm3.

Post-menopausal women (defined as no menses for at least 1 year) and surgically sterilized women are not required to undergo a pregnancy test. The definition of adequate contraception will be based on the judgment of the investigator. - Subjects (men and women) of childbearing potential must agree to use adequate contraception beginning at the signing of the informed consent form (ICF) until at least 3 months after the last dose of study drug. The definition of adequate contraception will be based on the judgment of the principal investigator or a designated associate. - Subject must be able to swallow and retain oral medication. - Discretionary use of growth factors allowed Exclusion Criteria: - Previous assignment to treatment during this study. Subjects permanently withdrawn from study participation will not be allowed to re-enter study. - Uncontrolled hypertension (systolic pressure >140 mm Hg or diastolic pressure > 90 mm Hg [NCI-Common Toxicity Criteria for Adverse Effects (CTCAE) v4.03] on repeated measurement) despite optimal medical management. - Evidence of remaining tumor - Has local or distant metastasis - Previous antiangiogenic treatment - Abnormal hematological, renal, or liver function - Impaired pulmonary function - Evidence of ≥ Grade 2 neuropathy - Active or clinically significant cardiac disease including: - Congestive heart failure - New York Heart Association (NYHA) > Class II. - Active coronary artery disease. - Cardiac arrhythmias requiring anti-arrhythmic therapy other than beta blockers or digoxin. - Unstable angina (anginal symptoms at rest), new-onset angina within 3 months before randomization, or myocardial infarction within 6 months before randomization. - Evidence or history of bleeding diathesis or coagulopathy. - Any hemorrhage or bleeding event ≥ NCI CTCAE Grade 3 within 4 weeks prior to start of study medication. - Subjects with thrombotic, embolic, venous, or arterial events, such as cerebrovascular accident (including transient ischemic attacks), deep vein thrombosis, or pulmonary embolism within 6 months of start of study treatment. - Subjects with any previously untreated or concurrent cancer that is distinct in primary site or histology from breast cancer except cervical cancer in-situ, treated basal cell carcinoma, or superficial bladder tumor.

Infrequent bleeding or elevations in PT-INR have been reported in some subjects taking warfarin while on regorafenib therapy. Therefore, subjects taking concomitant warfarin should be monitored regularly for changes in PT, PT-INR, or clinical bleeding episodes. - Low dose aspirin (≤ 100 mg daily). - Prophylactic doses of heparin. - Use of any herbal remedy (eg, St. John's wort [Hypericum perforatum]) Note: Granulocyte colony-stimulating factor (G-CSF) and other hematopoietic growth factors may be used in the management of acute toxicity, such as febrile neutropenia, when clinically indicated or at the investigator's discretion. However, they may not be substituted for a required dose reduction. Subjects are permitted to take chronic erythropoietin.
