Lung Cancer Clinical Trial

Topotecan Hydrochloride and Doxorubicin Hydrochloride in Treating Relapsed or Refractory Small Cell Lung Cancer

Summary

This phase I trial studies the side effects and best dose of topotecan hydrochloride when given together with doxorubicin hydrochloride in treating patients with small cell lung cancer (SCLC) that has come back after a period of improvement (relapsed) or has not responded to treatment (refractory). Drugs used in chemotherapy, such as topotecan hydrochloride and doxorubicin hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Doxorubicin hydrochloride may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving topotecan hydrochloride and doxorubicin hydrochloride may be a better treatment for small cell lung cancer.

PRIMARY OBJECTIVES:

I. Evaluate the safety and efficacy, in terms of clinical disease benefit, (complete or partial response and stable disease with stable or improved quality of life scores) of combination of oral topotecan (topotecan hydrochloride) when given with weekly doxorubicin (doxorubicin hydrochloride) in patients with SCLC.

II. Determine the dose limiting toxicity of oral topotecan when given with weekly doxorubicin in patients with SCLC.

SECONDARY OBJECTIVES:

I. Estimate topoisomerase I and II levels in peripheral blood mononuclear cells and correlate with presence or absence of grades 3 and 4 hematological toxicity.

II. Estimate topoisomerase I and II levels in peripheral blood mononuclear cells and correlate with efficacy.

OUTLINE: This is a dose-escalation study of topotecan hydrochloride.

Patients receive doxorubicin hydrochloride intravenously (IV) over 3-5 minutes on day 6 of course 1 and on days 6, 13, and 20 of courses 2-5. Patients also receive topotecan hydrochloride orally (PO) on days 1-5. Treatment repeats every 21 days for up to 5 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 2 months.

Exclusion Criteria:

Known hypersensitivity to any component of topotecan or doxorubicin or other required drugs in the study
Any co morbidity or condition which, in the opinion of the investigator, may interfere with the assessments and procedures of this protocol
Ejection fraction below the lower limit of normal (< 50%)
Uncontrolled intercurrent illnesses including, but not limited to unstable angina or uncontrolled cardiac arrhythmia, chronic liver disease, complete left bundle branch block, obligate use of a cardiac pacemaker, ST depression of > 1 mm in two or more leads and/or T wave inversions in two or more contiguous leads, congenital long QT syndrome, history of or presence of significant ventricular or atrial tachyarrhythmias, clinically significant resting bradycardia (< 50 beats per minute), corrected QT (QTc) > 480 ms on screening electrocardiogram that could jeopardize the patient?s ability to receive the chemotherapy described in the protocol safely
