ABSTRACT
BACKGROUND: This phase I study determined the maximum tolerated dose (MTD) of AUY922 with capecitabine in advanced solid tumors. METHODS: Capecitabine 1000 mg/m(2) PO BID was administered with escalating doses of AUY922 IV; the MTD of AUY922 was combined with capecitabine 1250 mg/m(2) (DL6). RESULTS: 23 patients were treated at 5 dose levels (22 mg/m(2)-70 mg/m(2)). No DLTs were observed until DL6 (grade 3 diarrhea). Reversible vision darkening was seen in 26%. Four patients had partial response; 2 previously progressed on fluorouracil. Eight patients had stable disease (median 25.5 weeks). CONCLUSION: AUY922 plus capecitabine was well-tolerated up to 70 mg/m(2) with encouraging preliminary efficacy.

PURPOSE: To evaluate the feasibility and efficacy of sorafenib and everolimus in renal cell carcinoma (RCC). METHODS: Patients with advanced RCC and ≤ 1 previous targeted therapy were treated. RESULTS: Maximum tolerated doses were sorafenib 200 mg PO BID, everolimus 35 mg PO once weekly. Dose-limiting toxicity was hand-foot syndrome. The response rate was 13%; median PFS was 5.45 months (95% CI: 3.8-7.6). Skin toxicity, fatigue, hypertension, proteinuria, and mucositis (usually Grade 2) were common. CONCLUSIONS: Fifty percent doses of sorafenib and everolimus were required when these drugs were combined. No increase in efficacy was suggested; toxicity was modestly increased.
