简要总结
Patients with advanced oesophagogastric cancer (OCG) have a very poor prognosis. After progression on first line therapy, second line chemotherapy with paclitaxel and a VEGF-R2 targeting antibody has a proven benefit on survival. However, no data are available on the combination of paclitaxel with kinase inhibitors in advanced OGC. Here the investigators propose a Phase 1b study to assess the tolerability of regorafenib (an oral multi kinase inhibitor) in combination with paclitaxel and to assess the uptake of paclitaxel in OCG metastasis.
详细描述
Rationale:
Regorafenib is a new oral multikinase inhibitor of angiogenic, stromal and oncogenic receptor tyrosine kinases. Regorafenib demonstrated to increase the overall survival of patients with metastatic colorectal cancer and has been approved by the U.S. Food and Drug Administration (FDA), as well as by The European Medicines Agency (EMA). In a recent phase IB study the combination of regorafenib with FOLFOX or FOLFIRI was shown to be a tolerable treatment regimen as first- or second-line treatment of colorectal cancer. Unfortunately, no data are available showing the effect of regorafenib on chemotherapy uptake in metastases. Here the investigators propose a phase IB study in advanced OGC with cytotoxic treatment consisting of paclitaxel together with regorafenib, to assess the tolerability of the combination as second line therapy for metastasized OGC and to assess the effect of regorafenib on paclitaxel uptake in OGC metastases.
Primary objectives:
To assess the tolerability of regorafenib combined with paclitaxel. Secondary objectives To assess the effect of regorafenib on uptake of paclitaxel in OGC metastases. To assess the effect of regorafenib on regorafenib targets in OGC metastases and blood samples.
To assess the effect of regorafenib on paclitaxel pharmacokinetics. To obtain exploratory data on the efficacy of the combination of regorafenib with paclitaxel.
