  • Note: Patients on full-dose anticoagulation must be on a stable dose (minimum duration 14 days) of oral anticoagulant or low molecular weight heparin (LMWH)
  • Exception: If receiving warfarin, the patient must have an INR =< 3.0. For heparin and LMWH there should be no active bleeding (that is, no bleeding within 14 days prior to first dose of protocol therapy) or pathological condition present that carries a high risk of bleeding (for example, tumor involving major vessels or known varices)

• Creatinine =< 1.5 times the ULN or creatinine clearance (measured via 24-hour urine collection) >= 50 mL/minute (that is, if serum creatinine is >= 1.5 times the ULN, a 24-hour urine collection to calculate creatinine clearance must be performed) (obtained =< 7 days prior to registration)

• Negative pregnancy test done =< 7 days prior to registration, for women of childbearing potential only

• Ability to complete questionnaire(s) by themselves or with assistance

• Provide informed written consent =< 28 days prior to registration

• Willing to return to enrolling institution for follow-up (during the Active Monitoring Phase of the study)

• Because the teratogenicity of ramucirumab is not known, the patient, if sexually active, must be postmenopausal, surgically sterile, or using effective contraception (hormonal or barrier methods)

Exclusion Criteria:

• Any of the following because this study involves an investigational agent whose genotoxic, mutagenic and teratogenic effects on the developing fetus and newborn are unknown:

  • Pregnant women
  • Nursing women
  • Women of childbearing potential who are unwilling to employ adequate contraception

• Co-morbid systemic illnesses or other severe concurrent disease which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and toxicity of the prescribed regimens

• Previous treatment with TAS-102 or ramucirumab

• Previous taxane therapy =< 180 days prior to registration

• Any grade 3-4 gastrointestinal (GI) bleeding =< 90 days prior to registration

• History of deep vein thrombosis (DVT), pulmonary embolism (PE), or any other significant thromboembolism (venous port or catheter thrombosis or superficial venous thrombosis are not considered "significant") =< 90 days prior to registration

• Any arterial thromboembolic events, including but not limited to myocardial infarction, transient ischemic attack, cerebrovascular accident, or unstable angina, =< 180 days prior to registration

• Prior history of GI perforation/fistula =< 180 days of registration or risk factors for perforation

• Serious or nonhealing wound, ulcer, or bone fracture =< 28 days prior to registration

• Cirrhosis at a level of Child-Pugh B (or worse) or cirrhosis (any degree) and a history of hepatic encephalopathy or clinically meaningful ascites resulting from cirrhosis. NOTE: Clinically meaningful ascites is defined as ascites from cirrhosis requiring diuretics or paracentesis

• Uncontrolled or poorly-controlled hypertension (>= 150 mmHg systolic or >= 90 mmHg diastolic for >= 4 weeks) despite standard medical management

• Immunocompromised and known to be human immunodeficiency virus (HIV) positive and currently receiving antiretroviral therapy

  • NOTE: Patients known to be HIV positive, but without clinical evidence of an immunocompromised state, are eligible for this trial

• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements

• Receiving any other investigational agent which would be considered as a treatment for the primary neoplasm

• Other active malignancy =< 3 years prior to registration. EXCEPTIONS: Non-melanotic skin cancer or carcinoma-in-situ of the cervix. NOTE: If there is a history of prior malignancy, they must not be receiving other specific treatment for their cancer

• Receiving chronic antiplatelet therapy, including dipyridamole or clopidogrel, or similar agents. NOTE: Once-daily aspirin use (maximum dose 325 mg/day) is permitted
