Obatoclax Mesylate and Topotecan Hydrochloride in Treating Patients With Relapsed or Refractory Small Cell Lung Cancer or Advanced Solid Tumors

Completed · Phase 1/Phase 2

Conditions studied: Recurrent Small Cell Lung Cancer, Unspecified Adult Solid Tumor, Protocol Specific

In brief

This phase I/II trial is studying the side effects and best dose of obatoclax mesylate when given together with topotecan hydrochloride and to see how well they work in treating patients with relapsed or refractory small cell lung cancer or advanced solid tumors. Obatoclax mesylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as topotecan hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving obatoclax mesylate together with topotecan hydrochloride may help kill more tumor cells
