Study of Axitinib for Reducing Extent of Venous Tumour Thrombus in Renal Cancer With Venous Invasion — NAXIVA  

Renal Cell Carcinoma Clinical Trial

Official title: NAXIVA- Phase II Neoadjuvant Study of Axitinib for Reducing Extent of Venous Tumour Thrombus in Clear Cell Renal Cell Cancer With Venous Invasion

Status Completed

Clinical Trial Summary

NAXIVA is a study of axitinib in patients with metastatic and non-metastatic renal cell carcinoma with venous invasion. Patients will be given axitinib (twice daily) for 8 weeks (at an escalated dose) and the response of the venous invasion will be assessed. Blood, urine and tumour tissue samples will be taken prior to and during therapy to evaluate biomarkers of treatment response. The primary objective is to assess the response of the thrombus to axitinib. Its thought that axitinib will reduce the extent of the thrombus in the inferior vena cava will reduce the extent of surgical intervention.

Clinical Trial Description

NAXIVA is a single arm, single agent, open label, phase II feasibility study of axitinib in patients with both metastatic and non-metastatic renal cell carcinoma of clear cell histology. 20 patients will be recruited from multiple centres within the United Kingdom. Patients who have signed informed consent and who have met all eligibility criteria will be registered into the trial. The starting dose of axitinib will be 5mg BID and escalated to 7mg BID and then 10mg BID. A dose modification assessment will take place every 2 weeks in clinic during the 8 week pre-surgical treatment period and will be dependent on tolerability of treatment. Patients will follow an aggressive axitinib dose escalation process within the 8 week period to a maximum of 10mg BID. Patients should stop axitinib a minimum of 36 hours and a maximum of 7 days prior to surgery in week 9. Blood, urine and tissue samples will be taken prior to and during therapy to evaluate biomarkers of treatment response. Nephrectomy and IVC tumour thrombectomy will be planned for all patients on the trial. Response to axitinib in VTT, primary tumour and any RECIST measureable lesion will be correlated with changes in molecular markers. Patients will be followed up in clinic at 6 & 12 weeks post surgery. ;
