  • Stage IV Small Intestinal Adenocarcinoma AJCC v8


This phase II trial studies how well ramucirumab and paclitaxel or the FOLFIRI regimen (leucovorin calcium, fluorouracil, and irinotecan hydrochloride) work in treating patients with small bowel cancers that have spread extensively to other anatomic sites (advanced) or are no longer responding to treatment (refractory). Ramucirumab is a monoclonal antibody that attaches to and inhibits a molecule called VEGFR-2. This may restrain new blood vessel formation therefore reducing nutrient supply to tumor which may interfere with tumor cell growth and expansion. Drugs used in chemotherapy, such as paclitaxel, leucovorin calcium, fluorouracil, and irinotecan hydrochloride work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving Ramucirumab plus paclitaxel or FOLFIRI, may be helpful in treating advanced or refractory small bowel cancers and may help patients live longer.

Study summary:

PRIMARY OBJECTIVES: I. To evaluate whether progression-free survival (PFS) meets an efficacy threshold in patients with previously treated advanced small bowel adenocarcinoma who receive treatment with ramucirumab and paclitaxel or FOLFIRI. II. If the stated threshold is met in both arms, to choose the better regimen with respect to progression free survival (PFS). SECONDARY OBJECTIVES: I. To assess overall response rate (ORR) [complete and partial, confirmed and unconfirmed] in the subset of patients with measurable disease treated with ramucirumab and paclitaxel or FOLFIRI in this patient population. II. To assess overall survival (OS) in patients treated with ramucirumab and paclitaxel or FOLFIRI in this patient population. III. To evaluate safety and toxicity associated with combination ramucirumab and paclitaxel treatment or FOLFIRI therapy in this patient population. TRANSLATIONAL OBJECTIVES: I. To explore the correlation of maximum decrease in CEA levels and time to maximum decrease in CEA levels with PFS, OS, and ORR. II. To bank tissue and blood samples for other future correlative studies from patients enrolled on the study. OUTLINE: Patients are randomized to 1 of 2 arms. ARM I: Patients receive ramucirumab intravenously (IV) over 30-60 minutes on days 1 and 15, and paclitaxel IV over 30 minutes on days 1, 8, and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. ARM II: Patients receive irinotecan IV over 90 minutes on days 1 and 15, leucovorin IV over 2 hours on days 1 and 15, and fluorouracil IV bolus on days 1 and 15. Patients also receive fluorouracil IV over 46-48 hours on days 1-3 and 15-17. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients completing study treatment are followed up every 8 weeks until disease progression. Once the disease has progressed, patients are followed up every 6 months for up to 3 years post registration.
