Brief Summary:
Phase 1/2, open-label, dose-escalation study to assess the safety and tolerability of GCS-100 in combination with etoposide and dexamethasone in patients with relapsed or refractory diffuse large B-cell lymphoma.

Condition or disease Intervention/treatment Phase
Diffuse Large B-cell Lymphoma Drug: GCS-100 Drug: Etoposide; Dexamethasone Phase 1 Phase 2

Detailed Description:
This study will investigate the safety and efficacy of the combination of GCS-100 with etoposide and dexamethasone. In vitro data demonstrates potentiation of the killing of lymphoma cells when GCS-100 is combined with dexamethasone or etoposide (Linda Baum, unpublished data; Finbarr Cotter et al, Annals of Oncology, vol 16, 205, Suppl 5.) GCS-100 will be administered in increasing doses to define a maximum tolerated dose (MTD) in combination with these chemotherapeutic agents. When the MTD is defined, the cohort will be expanded to characterize the efficacy of this combination.

Official Title: Phase 1/2 Study of GCS-100 in Combination With Etoposide and Dexamethasone in Relapsed or Refractory Diffuse Large B Cell Lymphoma
Study Start Date : July 2008
Actual Primary Completion Date : April 2009
Actual Study Completion Date : April 2009

Arm Intervention/treatment
Experimental: GCS-10 Drug: GCS-100
GCS-100 80 mg/m2 IV (in the vein) on Study Days 1, 2, 3, 4, and 5 of a 21-day course. Three or up to six patients will be enrolled in each cohort until the maximum tolerated dose is reached. The dose levels: 1) 80 mg/m2; 2) 120 mg/m2; 3) 160 mg/m2

Drug: Etoposide; Dexamethasone
Etoposide 100 mg/m2 on Study Days 3, 4 and 5; Dexamethasone 10 mg/m2 on Study Days 1, 2, 3, 4 and 5.
Other Names:
  • Eposin
  • VP-16
  • Etopophos
  • Vepesid
  • Decadron

Primary Outcome Measures :
  1. To determine the maximum tolerated dose of GCS-100 in combination with etoposide and dexamethasone by comprehensive lab, pharmacokinetics, physical assessments, and PET-CT imaging. [ Time Frame: Study Day 12 for toxicity, and 21-day cycles assessed every 2 cycles by physical and imaging assessments until disease progression ]

Secondary Outcome Measures :
  1. Overall response rate; correlate response to GCS-100 with the expression of galectin-3 in tumors; correlate serum galectin-3 levels with the administration of GCS-100 [ Time Frame: Baseline, Day 1, and Day 5 laboratory assessments ]
