GCS-100LE in Combination With Etoposide and Dexamethasone in Relapsed or Refractory Diffuse Large B-Cell Lymphoma

Phase 1
Withdrawn
Conditions
Diffuse Large B-cell Lymphoma
Interventions
Registration Number
NCT00776802
Lead Sponsor
La Jolla Pharmaceutical Company
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.

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potentiation of the killing of lymphoma cells when GCS-100 is combined with dexamethasone or etoposide (Linda Baum, unpublished data; Finbarr Cotter et al, Annals of Oncology, vol 16, 205, Suppl 5.)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