Abstract

Purpose: To evaluate the toxicity profile of inhalational doxorubicin in patients with malignant disease in the lung. Experimental Design: The OncoMyst Model CDD-2a inhalation device aerosolizes compounds to particles of 2 to 3 μm and prevents exhaled aerosol from escaping into the environment. Deposition efficiency of inhaled Technetium 99m was used to predict deposition of doxorubicin and calculate dose. Treatment was repeated every 3 weeks. No more than moderate pulmonary dysfunction was permitted (forced expiratory volume in 1 s, forced vital capacity, and diffusing capacity for carbon monoxide, all >50% predicted; resting SaO2 >90%). Results: Fifty-three patients were enrolled at 13 dose levels ranging from 0.4 to 9.4 mg/m 2. The most common histologic diagnoses were sarcoma (n = 19) and non-small cell lung cancer (n = 16). Dose-limiting toxicity (DLT) was observed at the 9.4 mg/m2 dose level when two of four patients experienced pulmonary DLT. Of 11 patients treated at the 7.5 mg/m2 dose level, only one showed DLT consisting of a decline in forced vital capacity of >20% from baseline. No significant systemic drug-related toxicity was observed. Several patients experienced declines in pulmonary function test variables, which were attributed to progressive disease. Observed activity included a partial response in a patient with metastatic soft tissue sarcoma previously treated with i.v. doxorubicin and ifosfamide. Conclusions: Inhaled doxorubicin is safe up to a dose of 7.5 mg/m2 every 3 weeks in patients with cancer who had normal to moderately impaired pulmonary function.
