Study Comparing Amrubicin Versus Topotecan in Patients With Small Cell Lung Cancer Who Have Responded to Prior Therapy.

Study Overview
=================
Brief Summary
-----------------
The purpose of the study is to evaluate the objective tumor response rate of amrubicin or standard topotecan therapy when administered as second-line therapy to ED-SCLC patients who have chemotherapy sensitive recurrent or progressive.

Official Title
-----------------
A Randomized Phase 2 Trial Comparing Amrubicin Versus Topotecan as Second-Line Treatment in Patients With Extensive Small Cell Lung Cancer Sensitive to First-Line Chemotherapy

Conditions
-----------------
Small Cell Lung Cancer

Intervention / Treatment
-----------------
* Drug: Amrubicin
* Drug: Topotecan


Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria: Histological or cytological diagnosis of SCLC Extensive disease (ED) at time of study entry Response to first-line platinum-based chemotherapy Recurrent or progressive SCLC ≥90 days after completion of first-line therapy At least 18 years of age ECOG Performance Status of 0, 1, or 2 Measurable disease defined by RECIST criteria Measurable disease: The presence of at least one measurable lesion. If only one lesion is present, the neoplastic nature of the disease site should be confirmed by histology and/or cytology. Measurable lesion: Lesions that can be accurately measured in at least one dimension with the longest diameter ≥20mm using conventional techniques or ≥10mm using spiral CT scans. CT (including spiral CT) scans and MRI are the preferred methods of measurement; however, chest x-rays are acceptable if the leions are clearly defined and surrounded by aerated lung. Clinically detected lesions will only be considered measurable when they are superficial (eg., skin nodules and palpable lymph nodes). For the case of skin lesions, documentation by color photography, including a ruler to estimate the size of the lesion is required. Adequate organ function including the following: Adequate bone marrow reserve: absolute neutrophil (segmented and bands) count (ANC) ≥1500 cells/μL, platelet count ≥100,000 cells/μL and hemoglobin ≥9 g/dL Hepatic: bilirubin ≤1.5 X ULN; alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤3.0 X ULN Renal: serum creatinine <2.0mg/dL or calculated creatinine clearance >60mL/min Cardiac: Left ventricular ejection fraction (LVEF) ≥50% Negative serum pregnancy test at the time of enrollment for women of child-bearing potential. For men and women of child-producing potential, use of effective contraceptive methods during the study. Ability to understand the requirements of the study, provide written informed consent and authorization of use and disclosure of protected health information, and agree to abide by the study restrictions and to return for the required assessments Exclusion Criteria: Pregnant or nursing women Chest radiotherapy within the previous 28 days or other radiotherapy within the previous 14 days. Recovery from the acute toxic effects of radiation required prior to study enrollment. Measurable lesions that have been previously irradiated must be enlarging to be considered target lesions. Prior radiation therapy allowed to <25% of the bone marrow. More than 1 prior chemotherapy regimen for SCLC Prior anthracycline treatment Participation in any investigational drug study within 28 days prior to study entry Patients with second primary malignancy (except in situ carcinoma of the cervix or adequately treated nonmelanomatous carcinoma of the skin or other malignancy treated at least 5 years previously with no evidence of recurrence; prior low grade [Gleason score ≤6] localized prostate cancer is allowed) Concurrent severe or uncontrolled medical disease (i.e., active systemic infection, diabetes, hypertension, coronary artery disease, congestive heart failure) that, in the opinion of the Investigator, would compromise the safety of the patient or compromise the ability of the patient to complete the study. Symptomatic central nervous system metastases. Patients with asymptomatic brain metastases are allowed. The patient must be stable after radiotherapy for ≥2 weeks and off corticosteroids for ≥1 week. History of interstitial lung disease or pulmonary fibrosis
