Safety and MTD [ Time Frame: First 3 weeks ]
  • Maximum tolerated dose will be determined by the observed occurrence of dose limiting toxicities [ Time Frame: First 3 weeks ]
  • Tolerability of each dose administration [ Time Frame: First 3 weeks ]
  • The safety of GRN163L will be evaluated by PE, lab toxicity, and the incidence and severity of AEs. [ Time Frame: Baseline to 28 days after the last dose of treatment ]

PK, PD, and efficacy [ Time Frame: Baseline to end of treatment ]
  • Pharmacokinetics will be determined by serial measurements of its concentration in plasma [ Time Frame: Baseline to end of treatment ]
  • Efficacy will be determined by evidence of OR, DOR from the first recorded achievement of the response and TTP from the start of treatment. [ Time Frame: Start of treatment to time to progression ]
  • Pharmacodynamic markers from blood and bone marrow will be determined by inhibition of telomerase activity, markers of apoptosis, changes in normal and neoplastic cell telomere length and effects upon myeloma stem cell subpopulations. [ Time Frame: Baseline to end of treatment ]

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