RESULTS:
In  the Perifosine 228 trial, 1 patient achieved a partial response  (objective response rate, 4%; 95% confidence interval, 0.7%-20%), and 11  patients (46%) had stable disease as their best response. The median  progression-free survival was 14.2 weeks (95% confidence interval,  7.7-21.6 weeks). In the Perifosine 231 trial, 5 patients achieved a  partial response (objective response rate, 10%; 95% confidence interval,  4.5%-22.2%) and 16 patients (32%) had stable disease as their best  response. The median progression-free survival was 14 weeks (95%  confidence interval, 12.9, 20.7 weeks). Overall, perifosine was well  tolerated, and there were very few grade 3 and 4 events. The most common  toxicities included nausea, diarrhea, musculoskeletal pain, and  fatigue.
CONCLUSIONS:
Although  perifosine demonstrated activity in patients with advanced RCC after  failure on VEGF-targeted therapy, its activity was not superior to  currently available second-line agents. Nonetheless, perifosine may be  worthy of further study in RCC in combination with other currently  available therapies.
