Popis: Background: The objectives of this phase I study were to assess the safety and tolerability of E7080 in patients with advanced, refractory solid tumours; to determine the maximum tolerated dose (MTD) and pharmacokinetics profile of E7080; and to explore preliminary evidence of its anti-tumour efficacy. Methods: E7080 was administered orally in escalating doses on a once-daily continuous schedule in 28-day cycles to eligible patients. Samples for pharmacokinetic analyses were collected on days 1, 8, 15 and 22 of cycle 1 and day 1 of cycle 2. Anti-tumour efficacy was assessed every two cycles. Results: Eighty-two patients received E7080 in dose cohorts from 0.2 to 32 mg. Dose-limiting toxicities were grade 3 proteinuria (two patients) at 32 mg, and the MTD was defined as 25 mg. The most frequently observed cumulative toxicities (all grades) were hypertension (40% of patients), diarrhoea (45%), nausea (37%), stomatitis (32%) and vomiting (23%). Seven patients (9%) had a partial response and 38 patients (46%) had stable disease as best response. E7080 has dose-linear kinetics with no drug accumulation after 4 weeks' administration. Conclusion: E7080 is well tolerated at doses up to 25 mg per day. Encouraging anti-tumour efficacy was observed in patients with melanoma and renal cell carcinoma.
