Further study details as provided by Geron Corporation:

Primary Outcome Measures:
  • Safety, tolerability, dose-limiting toxicities (DLT), and maximum tolerated dose (MTD) or recommended phase II dose of GRN163L in patients with relapsed or refractory chronic lymphoproliferative disease [ Time Frame: First 3 weeks ]

Secondary Outcome Measures:
  • PK and PD [ Time Frame: Measured in the first 6 weeks ]

Estimated Enrollment: 48
Study Start Date: July 2005
Study Completion Date: March 2013
Primary Completion Date: March 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
open label
Sequential dose cohort, open label, escalation trial evaluating one infusion duration of 2 hours
Drug: GRN163L
Weekly intravenous infusion

Detailed Description:
Imetelstat Sodium (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. High telomerase levels and short telomere lengths correlate with other markers of poor prognosis in patients with chronic lymphoproliferative disease.
