Pre-operative Administration of Sorafenib in Patients With Metastatic Renal Cell Carcinoma Undergoing Kidney Removal
Pre-operative Administration of Sorafenib in Patients With Metastatic Renal Cell Carcinoma Undergoing Cytoreductive Nephrectomy
The purpose of this study is to see if preoperative administration of Sorafenib reduces the size of the primary kidney tumour in patients with metastatic disease undergoing cytoreductive surgery.
The study will also assess the safety of preoperative Sorafenib.
The study drug, Sorafenib, will be given to patients preoperatively for 12 weeks. After a 1 week washout period the patient will then have their nephrectomy (kidney removed). Approximately 6 weeks following their nephrectomy, patients will resume on study drug until disease progression.

Intervento / Trattamento |
|---|---|

Sperimentale: Sorafenib
All patients on study will be accrued to this arm.
Sorafenib (200 mg tablets x 2) will be administered orally twice a day for 12 weeks (full daily dose of 800 mg).
Patient visits for safety will be conducted at least every 4 weeks.
Sorafenib dose reductions for drug-related toxicity will be applied based on considerable prior clinical experience.
Surgery will be performed at the completion of the 13th week, allowing for a one-week "washout" period.
Sorafenib will be continued post operatively (around 6 weeks post surgery or when complete wound healing has occurred) until patient progresses or unacceptable toxicity occurs.
|
Starting dose: 400 mg (2x200mg tablets) BID (total= 800mg/day) taken orally.
The dose can be adjusted as per investigator if required due to toxicity (ex.
200mg BID, 200mg QD).
Study drug is taken for 12 weeks preoperatively.
Patients restart on study drug 6 weeks postoperatively and continue until progression or unacceptable toxicity occurs.
