| Neuroendocrine Tumors | Drug: Drug: Everolimus Drug: STZ-5FU | Phase 3 |
STZ based chemotherapy, STZ-5FU, is the actual standard of care for advanced pancreatic Neuroendocrine tumours (pNETS) in the European Union. Everolimus has been recently approved for its use in advanced pNETs by the Food and Drug Administration (FDA) and in Europe by the European Medical Agency (EMA).
A randomized study is needed to have a clear knowledge about the best sequence for its administration; this is, before or after palliative chemotherapy.
There may or may not be any benefits from giving first each other treatment of the study. The information obtained from this study will help the physician improve the treatment and management of patients with advanced pNET.
This study was planned to compare STZ-5FU chemotherapy followed by everolimus upon progression versus the reverse sequence. However sequential studies with pNETs are hard to be managed in terms of time and costs. Therefore the protocol was amended to have PFS1 (progression free survival after course 1) as primary endpoint and PFS2 (i.e. progression free survival after both STZ based chemotherapy and Everolimus or the reverse order) as secondary endpoint. This information will be extremely valuable for the day to day clinical practice of NET oncologists
