Clinical Evaluation of the Delivery and Safety of Aerosolized Liposomal 9-Nitro-20(S)-Camptothecin in Patients with Advanced Pulmonary Malignancies

Abstract

Aerosol administration of liposomal 9NC was found to be feasible and safe. 9NC delivered as an aerosol was detected in patient's plasma shortly after the start of treatment. The recommended dose for Phase II studies is 13.3 micro g/kg/day (equivalent to 0.5 mg/m(2)/day), which constitutes two consecutive 30-min nebulizations/day from a nebulizer reservoir with 4 mg of 9NC in 10 ml of sterile water, Monday to Friday for 8 weeks every 10 weeks.
