Cabazitaxel is a new taxoid, which promotes tubulin assembly and has shown strong antitumor activity against a broad spectrum of tumor models including those sensitive as well as resistant or refractory to other taxanes such as docetaxel. This is a Phase I safety and pharmacokinetic study of XRP6258 (Cabazitaxel) in advanced solid tumor patients with varying degrees of hepatic impairment.
Halaven is a synthetic analogue of the marine spong natural product halichondrinB. As an inhibitor of microtubules it blocks the cell division and leads to apoptosis of the cancer cells. In this study Halaven is administered on days 1 and 8 of a 21 day cycle in patients with solid tumors who also have impaired renal function.
