Summary

The purpose of this study is to test the safety and efficacy of drug, TAS-102 (trifluridine/tipiracil), in patients with extrapulmonary (outside the lung) high-grade neuroendocrine cancer. TAS-102 demonstrated improved survival and tolerability in patients with colorectal cancer and is currently approved by the FDA and marketed under the brand name Lonsurf for the treatment of patients with metastatic colorectal cancer (mCRC). Recently, a study evaluating TAS-102 showed a case of complete remission of high-grade NEC. Given the safety profile of TAS-102 and the remarkable single agent activity in a disease with otherwise dismal outcomes, we hope that TAS-102 may show tolerability and efficacy in neuro-endocrine cancer and propose further exploration in patients with extrapulmonary (outside the lung) high-grade neuroendocrine cancer.

Conditions

  • High-grade Extra Pulmonary Neuroendocrine Cancer

Interventions

DRUG

All patients- TAS-102

Patients will receive TAS-102, Orally, BID for 5 days a week with 2 days rest for 14 days, followed by a 14-day rest treatment cycle. Treatment may continue until disease progresses, intolerable toxicity is developed, or if the patient becomes pregnant or dies.
