ASA404 (5,6‐dimethylxanthenone‐4‐acetic acid, vadimezan), a flavone‐8‐acetic acid analogue, is a novel tumor‐vascular disrupting agent. In this study, the safety and tolerability, pharmacokinetics and pharmacodynamics of ASA404 in combination with standard therapy of paclitaxel and carboplatin (P/C) were assessed. A total of 15 Japanese patients with stage IV advanced non‐small cell lung cancer were enrolled and P/C plus ASA404 at three dose levels (600–1800 mg/m 2 ) was administered every 3 weeks. Dose limiting toxicities were observed in two patients during Cycle 1 of ASA404 treatment (Grade 3 febrile neutropenia at ASA404 1200 mg/m 2 and Grade 3 QT prolongation at ASA404 1800 mg/m 2 ) and the incidence of dose limiting toxicity was ≤1/3. The most frequently reported adverse events were injection site pain, peripheral sensory neuropathy, alopecia, neutropenia, nausea, anorexia and arthralgia, which were similar to those seen in previous Phase I/II studies. Pharmacokinetic analysis revealed the plasma area under the curve (AUC) of total ASA404 increased in a mostly dose‐proportional manner within the dose range investigated. Administration of ASA404 raised plasma 5‐hydroxyindole‐3‐acetic acid level dose‐dependently by 116 and 204% after 1200 and 1800 mg/m 2 doses, respectively. Partial response was observed in four patients (27%), and seven patients (47%) exhibited stable disease. Overall, the safety and preliminary efficacy profiles were comparable to those seen in non‐Japanese patients in previous Phase I and Phase II studies, and support the further evaluation of ASA404 (1800 mg/m 2 ) in Phase III studies in combination with P/C in Japanese patients with advanced non‐small cell lung cancer.
