regorafenib in good performance status patients with newly diagnosed metastatic colorectal adenocarcinoma

Conditions: Metastatic Colorectal Adenocarcinoma

Summary: the purpose of this study is to evaluate the good and bad effects when regorafenib is used instead of standard combination chemotherapy. it is not known if taking regorafenib versus standard chemotherapy will have better, worse or the same results.


Eligibility criteria:
inclusion criteria: * age ≥ 18 years. * life expectancy of at least 12 weeks (3 months). * untreated for metastatic colorectal cancer, or progression on any first line 5-fu containing regimen (such as folfox or folfiri) * histologically proven colorectal adenocarcinoma * metastatic disease, unresectable disease involving one or more sites including liver, lung, lymph nodes and peritoneum, with each nodule measuring ≤3cm or no more than two sites of disease (two nodules) \>4.5 cm. * ecog 0 or 1 * adequate bone marrow, liver and liver function as assessed by the following laboratory requirements: * total bilirubin ≤ 1.5 x the upper limits of normal (uln) * alanine aminotransferase (alt) and aspartate amino-transferase (ast) ≤ 2.5 xuln (≤ 5 x uln for subjects with liver involvement of their cancer) * alkaline phosphastase limit ≤ 2.5 x uln (≤ 5 x uln for subjects with liver involvement of their cancer) * lipase ≤ 1.5 x the uln * creatinine ≤ 1.5 x the uln * platelet count ≥ 100000 /mm3 * hemoglobin (hb) ≥ 9 g/dl, * absolute neutrophil count (anc) ≥ 1500/mm3. * blood transfusion to meet the inclusion criteria will not be allowed. * women of childbearing potential must have a negative serum pregnancy test performed within 7 days prior to the start of study drug. post-menopausal women (defined as no menses for at least 1 year) and surgically sterilized women are not required to undergo a pregnancy test. * subjects (men and women) of childbearing potential must agree to use adequate contraception beginning at the signing of the 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 site principal investigator or a designated associate. * subject must be able to swallow and retain oral medication. * if the patient is enrolled at msk he/she must consent to a pre and post treatment biopsy (or have archived tissue available for the pretreatment analysis). pretreatment archival tissue for patients enrolled outside of msk should be submitted to msk. if there is no archival tissue available, a repeat biopsy is not required for non-msk patients. exclusion criteria: * uncontrolled hypertension (systolic pressure \>140 mm hg or diastolic pressure \> 90 mm hg \[nci-ctcae v4.0\] on repeated measurement) despite optimal medical management. * 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 any previously untreated or concurrent cancer that is distinct in primary site or * recent history of prior cancer except cervical cancer in situ, treated basal cell carcinoma, or superficial bladder tumor. subjects surviving a cancer that was curatively treated and without evidence of disease for more than 3 years before enrollment are allowed. * known history of human immunodeficiency virus (hiv) infection or current chronic or active hepatitis b or c infection requiring treatment with antiviral therapy. * ongoing infection \> grade 2 nci-ctcae v4.0. * symptomatic metastatic brain or meningeal tumors. * presence of a non-healing wound, non-healing ulcer, or bone fracture. * patients with seizure disorder requiring medication. * interstitial lung disease with ongoing signs and symptoms at the time of informed consent. * pleural effusion or ascites that causes respiratory compromise (≥ nci-ctcae version 4.0 grade 2 dyspnea). * history of organ allograft (including corneal transplant). * any malabsorption condition. * women who are pregnant or breast-feeding. * any condition which, in the investigator's opinion, makes the subject unsuitable for trial participation. * major surgical procedure, open biopsy, or significant traumatic injury within 28 days before start of study medication.
