|Metastatic Renal Cell Carcinoma||Drug: Cabozantinib||Phase 2|
Cabozantinib is a small molecule inhibitor of tyrosine kinases which include MET (hepatocyte growth factor receptor protein), VEGFR (vascular endothelial growth factor receptors), AXL, RET (Rearranged during transfection), FLT3 (Fms-like tyrosine kinase-3), KIT (mast/stem cell factor receptor), ROS1, MER, TYRO3, TRKB (Tropomyosin receptor kinase B) and TIE-2 (angiopoietins receptor). Similar to other TKIs, cabozantinib is a reversible, ATP-competitive inhibitor. Cabozantinib has thus demonstrated significant activity in metastatic clear cell renal cell carcinoma after failure of one or 2 tyrosine kinase inhibitors and is now approved in the second line setting in Europe. Some efficacy was also demonstrated in patients in first line treatment when compared to sunitinib.
Brain metastasis in renal cancer are difficult to treat and cytotoxic systemic therapies are still not used, given by the more or less impermeable blood-brain barrier. The interest of cabozantinib in brain renal cell carcinoma metastases is encouraged by 3 recent cases reports of significant responses of brain metastases including a complete response of brain metastases in one case. Moreover MET receptor surexpression appear more frequent in brain metastases than in other renal cell carcinoma tumor sites. Cabozantinib as multitarget inhibitor including VEGF and MET receptors suggest that it could be a good option. Its efficacy in brain metastases from renal cell carcinoma requires further evaluation.
On this basis, the investigators propose to conduct an open-label exploratory single arm, multicenter prospective phase II trial to assess the efficacy of cabozantinib on brain metastases in metastatic renal cell carcinoma patients.
The relationship between serum markers and efficacy data will be investigated. Serum and plasma sample will be collected at Baseline. MET expression and MET sequencing will be also performed on available tumor tissues.

Experimental: Cabozantinib treatment
All participants will be treated by 60 mg of cabozantinib once daily.
All participants will be treated by 60 mg of cabozantinib once daily. Temporary or permanent discontinuation and/or dose reduction of cabozantinib therapy may be required for the management of some adverse reactions. When dose reduction is necessary, it is recommended to reduce to 40 mg daily, and then to 20 mg daily.
- The non progression rate in brain metastases at 3 months [ Time Frame: At 3 months for each patient ]Tumor assessment in brain will be performed by cerebral MRI at baseline, 1.5 months and 3 months. These cerebral MRI will be reviewed by central review according to the RANO-BM criteria.
- Incidence of adverse events [ Time Frame: Up to 54 months ]Assessed using the National Cancer Institute - Common Terminology Criteria for Adverse Event (NCI-CTCAE) v5 grading scale, specific registration of neurological event during study duration.
- Best response in brain metastases [ Time Frame: Up to follow-up visit month 18 for each patient ]Evaluated according to RANDO-BM criteria.
- Duration of response in brain [ Time Frame: Up to 18 months for each patient ]From the date of inclusion to the date of first documented disease progression.
- Progression-free survival [ Time Frame: Up to 18 months for each patient ]Measured from the date of inclusion to the date of first documented disease progression or death from any cause.
- Overall survival [ Time Frame: Up to 54 months ]Measured from the date of inclusion to the date of death from any cause.
