A Phase I Trial of Bortezomib and Sunitinib
The purpose of this study is to test the effect of the combination of sunitinib and bortezomib. We will see what effects it has on your cancer and find the highest dose of each agent that can be given without causing severe side effects.

Drug: Sunitinib and Bortezomib
This is a Phase I study assessing the combination of bortezomib and sunitinib in patients with solid tumors that are refractory to standard chemotherapy.
The study will take place in two stages. In both stages, patients will receive sunitinib orally with food once daily for 4 weeks and bortezomib by injection into a vein once a week for 4 weeks. This will be followed by 2 weeks of rest. This 6-week period is called one cycle.
In stage 1, a maximum of 10 patients will be treated sequentially with increasing doses of sunitinib (and a fixed dose of bortezomib). Each dose level must be well tolerated for the next patient to start treatment at the next dose level. Whichever is the highest dose of sunitinib that is well tolerated will then be used for the next stage.
In stage 2, a maximum of 20 patients will be treated sequentially with increasing doses of bortezomib (and a fixed dose of sunitinib). Each dose level must be well tolerated for the next patient to start treatment at the next dose level.
Together, the two stages will determine the highest doses of both sunitinib and bortezomib that are well tolerated when given this combination. Determining these optimal doses is the primary aim of this study. Patients will also be followed to see whether their tumor responds to the treatment.
If a patient's cancer remains stable or improves, they can repeat the treatment cycles. There is no defined end date to this study since patients will be followed for the duration of their survival.
