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

Recurrent Small Cell Lung Carcinoma Clinical Trial

Official title: A Phase I Study of Weekly Doxorubicin and Oral Topotecan for Patients With Relapsed or Refractory Small Cell Lung Cancer (SCLC)

Status Completed

Clinical Trial 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.

Clinical Trial Description

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. ;
