Safety and Dose Study of GRN163L Administered to Treat Patients With Refractory or Relapsed Multiple Myeloma

December 22, 2015 updated by: Geron Corporation

A Phase 1 Sequential Cohort, Dose Escalation Trial to Determine the Safety, Tolerability, and Maximum Tolerated Dose of GRN163L in Patients With Refractory or Relapsed Multiple Myeloma

The purpose of this study is to determine the safety and the maximum tolerated dose (MTD) of GRN163L when administered to patients with refractory or relapsed multiple myeloma.

Detailed Description

GRN163L is a telomerase template antagonist with in vitro and in vivo activity in a variety of tumor model systems. Telomerase is an enzyme that is active primarily in tumor cells and is crucial for the indefinite growth of tumor cells. Inhibition of telomerase may result in antineoplastic effects.
