Study & Design
- Study Type
- INTERVENTIONAL
- Study Design
- PARALLEL
- Primary Outcome Measures
Name Time Method To compare the overall survival associated with edotecarin versus that associated with temozolomide or BCNU or CCNU for the treatment of patients with GBM at first relapse previously treated with alkylator-based (neo)adjuvant therapy
- Secondary Outcome Measures
Name Time Method To assess measures of tumor control To evaluate measures of clinical benefit To assess the safety profile of edotecarin To assess the PK profile of edotecarin and the potential for drug interactions between anticonvulsants and edotecarin
