A Bioequivalence Study of Two Oral Formulations of Topotecan in Patients With Advanced Solid Tumors

A Study to Determine the Bioequivalence of an Oral Formulation of Topotecan Containing the Drug Substance Manufactured by New Process Relative to the Current Study Formulation of Topotecan in Patients With Advanced Solid Tumors


Lead Sponsor: GlaxoSmithKline

Brief Summary

The purpose of this study is to compare two capsules of topotecan made by slightly different methods. This will be done by giving the drug made by the two different methods to patients orally and testing blood levels.

- Patients with confirmed advanced solid tumors.

- No prior chemotherapy within 5 years of the diagnosis of SCLC (small cell lung cancer).

- At least 4 weeks since last chemotherapy, radiotherapy, biologic therapy or surgery.
