N2 - BACKGROUND: Epidermal growth factor receptor (EGFR) is overexpressed in 80%-90% of non-small-cell lung cancer (NSCLC). Matuzumab, a humanized immunoglobulin G(1) (IgG(1)) anti-EGFR monoclonal antibody, blocks activation of EGFR. Paclitaxel and EGFR inhibitors have additive antitumour effects in vitro. This phase I study assessed the tolerability, pharmacokinetics and efficacy of the combination of matuzumab and paclitaxel in patients with advanced NSCLC.MATERIALS AND METHODS: Eighteen chemotherapy-naïve (n = 9) or pretreated (n = 9) patients with stage IIIB or IV EGFR-positive NSCLC received weekly doses of matuzumab (100, 200, 400 or 800 mg) followed by paclitaxel 175 mg/m(2) every 3 weeks. Toxicity was evaluated weekly and pharmacokinetics were measured during cycles 1 and 2.RESULTS: The maximum planned matuzumab dose of 800 mg was achieved without reaching the maximum tolerated dose. Grade 4 neutropenia occurred in one of three patients at 800 mg but resolved within 1 week; five additional patients treated with 800 mg had no dose-limiting toxicity (DLT). Grade 1/2 acneiform skin rash in 14 patients was the most frequent matuzumab-related side-effect. There were no higher-grade adverse events. Grade 2 toxicities included pruritus (n = 2), bronchospasm (n = 1), fissures (n = 1), abdominal pain (n = 1) and hot flushes (n = 1). Paclitaxel was discontinued in four patients due to allergic reactions. Coadministration of paclitaxel did not alter matuzumab pharmacokinetics. Responses occurred in four of 18 patients and included one complete response.CONCLUSIONS: Matuzumab doses up to 800 mg weekly with paclitaxel 175 mg/m(2) every 3 weeks are well tolerated, with no apparent drug interactions and with evidence of antitumor activity.
