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potentiation of the killing of lymphoma cells when GCS-100 is combined with dexamethasone or etoposide (Linda Baum, unpublished data; Finbarr Cotter et al, Annals of Oncology, vol 16, 205, Suppl 5.)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.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

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 ]
