Renal cell carcinoma (RCC) accounts for 90% of kidney cancer cases, of which approximately 70% are of the clear cell carcinoma (ccRCC) subtype
.
Other histological variants, collectively termed non-clear cell renal carcinoma (nccRCC), include genetically and histologically diverse tumors
This study was designed to evaluate the efficacy and safety of cabozantinib combined with nivolumab in the treatment of non-clear cell renal cancer
.
Recruited patients with advanced non-clear cell renal cancer who had not received immune checkpoint inhibitor therapy before and received 0-1 previous treatments and received cabozantinib 40 mg (1/day) + nivolumab 240 mg (1 /2 weeks) or 480 mg (1/4 weeks)
.
Cohort 1 included papillary, unclassified, or translocation-related renal cell carcinoma; cohort 2 included chromophobe renal cell carcinoma

Objective response rates for cohort 1 and cohort 2
Objective response rates for cohort 1 and cohort 2A total of 47 patients were recruited with a median follow-up of 13.
1 months
.
In Cohort 1 (n=40), the objective response rate was 47.
In Cohort 1 (n=40), the objective response rate was 47.
PFS and OS in cohort 1 patients
PFS and OS in cohort 1 patientsGrade 3/4 treatment-related adverse reactions were reported in 32% of patients
.
Cabozantinib and nivolumab were discontinued due to toxicity in 13% and 17% of patients, respectively
Objective responses were achieved in 10 of 12 patients with NF2 or FH mutations
Cabozantinib in combination with nivolumab has shown promising efficacy in most non-clear cell renal cancers, especially in the subtype with papillary features .
