Methods: In this small prospectively randomized phase IIa multicenter trial, we investigated temsirolimus (TEM) versus sunitinib (SUN) as first-line therapy in patients with metastatic nccRCC. The patients were randomized 1:1 to either TEM in a dose of 25 mg i.v. once a week or SUN with 50 mg p.o. daily for 4 weeks on and 2 weeks off. Primary endpoint was progression-free survival (PFS). In total, 22 patients were included with predominantly papillary RCC (16/22) followed by chromophobe RCC and others. Results: The male to female ratio was 16:6. The tumor control rate (CR + PR + SD) was 58% for TEM and 90% for SUN-treated patients. There was also a trend for improved PFS with 9.3 versus 13.2 months (HR 1.64; 95% CI 0.65–4.18) in favor of SUN. There was no trend for overall survival. Conclusions: Despite this trial had to be terminated earlier due to low recruitment, the results match the other studies published so far with the mTOR inhibitor everolimus and SUN, which show a trend in favor of SUN for ORR and PFS.
