Inhaled Doxorubicin in Treating Patients With Advanced Solid Tumors Affecting the Lungs

OBJECTIVES:

• Determine the maximum tolerated dose and phase II dose of inhaled doxorubicin in patients with advanced solid tumors affecting the lungs.
• Determine the toxicity of this regimen in these patients.
• Determine the pharmacokinetic profile of inhaled doxorubicin in blood in these patients.
• Determine the relationship between pharmacodynamic parameters and toxic effects of this regimen in these patients.

OUTLINE: This is a dose-escalation study.

Patients receive inhaled doxorubicin every 3 weeks for up to 3 doses. Patients with stable or responding disease may receive additional doses in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of doxorubicin until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.

Patients are followed at 3 weeks and 3 months.

PROJECTED ACCRUAL: Approximately 33 patients will be accrued for this study within 18-24 months.
