Description

Summary

This randomized phase II trial studies how well temozolomide and capecitabine work compared to standard treatment with cisplatin or carboplatin and etoposide in treating patients with neuroendocrine carcinoma of the gastrointestinal tract or pancreas that has spread to other parts of the body (metastatic) or cannot be removed by surgery. Drugs used in chemotherapy, such as temozolomide, capecitabine, cisplatin, carboplatin and etoposide, 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. Certain types of neuroendocrine carcinomas may respond better to treatments other than the current standard treatment of cisplatin and etoposide. It is not yet known whether temozolomide and capecitabine may work better than cisplatin or carboplatin and etoposide in treating patients with this type of neuroendocrine carcinoma, called non-small cell neuroendocrine carcinoma.

Official Title

Randomized Phase II Study of Cisplatin and Etoposide Versus Temozolomide and Capecitabine in Patients With Advanced G3 Non-small Cell Gastroenteropancreatic Neuroendocrine Carcinomas

Details

PRIMARY OBJECTIVES:

  1. To assess the progression free survival (PFS) of platinum (cisplatin or carboplatin) and etoposide versus the PFS of temozolomide and capecitabine in patients with advanced G3 non-small cell gastroenteropancreatic neuroendocrine carcinomas.

SECONDARY OBJECTIVES:

  1. To assess the response rate (RR) of platinum (cisplatin or carboplatin) and etoposide versus the RR of temozolomide and capecitabine in patients with advanced G3 non-small cell gastroenteropancreatic neuroendocrine carcinomas.

II. To assess the overall survival (OS) of platinum (cisplatin or carboplatin) and etoposide versus the OS of temozolomide and capecitabine in patients with advanced G3 non-small cell gastroenteropancreatic neuroendocrine carcinomas.

III. To evaluate the toxicities associated with the combination of temozolomide and capecitabine and the combination of platinum (cisplatin or carboplatin) and etoposide, respectively, in patients with advanced G3 non-small cell gastroenteropancreatic neuroendocrine carcinomas.

TERTIARY OBJECTIVES:

  1. To assess the impact of each treatment regimen on PFS, RR and OS based on marker of proliferation Ki-67 index in patients with advanced G3 non-small cell gastroenteropancreatic neuroendocrine carcinomas. (Laboratory) II. To assess the prognostic significance of well differentiated versus poorly differentiated non-small cell gastroenteropancreatic neuroendocrine tumors in relationship to survival and response to treatment. (Laboratory) III. To assess the agreement in Ki-67 status between that reported by institutional pathologist and that reported by central pathology review. (Laboratory)

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM A: Patients receive capecitabine orally (PO) twice daily (BID) on days 1-14 and temozolomide PO once daily (QD) on days 10-14. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

ARM B: Patients receive cisplatin intravenously (IV) on days 1-3 or carboplatin IV on day 1. Patients also receive etoposide IV on days 1-3. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 3 years.
