Topotecan Hydrochloride and Doxorubicin Hydrochloride in Treating Patients With Small Cell Lung Cancer That Has Relapsed or Not Responded to Treatment
This phase I trial is studying 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 returned or not responded to treatment. 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.

|Official Title:||A Phase I Study of Weekly Doxorubicin and Oral Topotecan for Patients With Relapsed or Refractory Small Cell Lung Cancer (SCLC)|
- Maximum tolerated dose defined as the next lowest dose level below where greater than or equal to 2/3 or 3/6 patients experience dose limiting toxicities in cohorts of 5 different doses by National Cancer Institute Common Toxicity Criteria version 3.0 [ Time Frame: Up to 6 weeks (after 2 courses) ] [ Designated as safety issue: Yes ]The actual rates of dose limiting toxicities per dose cohort will be presented when applicable.
- Changes in topoisomerase I and II levels in peripheral blood mononuclear cells [ Time Frame: Baseline to up to week 16 ] [ Designated as safety issue: No ]The changes over time will be described and correlated with hematological toxicity and efficacy. Mean change and standard deviation over time will be computed and when possible change in topoisomerase levels over time will be compared between patients developing grade 4 hematological toxicities versus others (no toxicity or grades 1-3) or between patients developing grades 3-4 non-hematological toxicities versus others (no toxicity or grades 1-2) or between patients who responded (complete response, partial response, stable disease) versus no response or progressed using non-parametric tests.

Experimental: Treatment (doxorubicin hydrochloride, topotecan hydrochloride)
Patients receive doxorubicin hydrochloride IV weekly beginning on day 6 in weeks 1-15. Patients also receive topotecan hydrochloride PO on days 1-5 in weeks 1, 4, 7, 10, and 13 in the absence of disease progression or unacceptable toxicity.

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.
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) weekly beginning on day 6 in weeks 1-15. Patients also receive topotecan hydrochloride orally (PO) on days 1-5 in weeks 1, 4, 7, 10, and 13 in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 2 months.
