Phase II Study of PF-04948568 (CDX-110) in Patients With Glioblastoma Multiforme - Full Text View

Sponsors and Collaborators:	Pfizer Celldex Therapeutics
Information provided by:	Pfizer
ClinicalTrials.gov Identifier:	NCT00458601

Purpose

This study is designed to evaluate the clinical activity of CDX-110 vaccination when given with standard of care treatment (maintenance temozolomide therapy). Study treatment will be given until disease progression and patients will be followed for long-term survival information. Efficacy will be measured by the progression-free survival status at 5.5 months from the date of first dose.

Primary Outcome Measures:

Progression-free survival status [ Time Frame: 5.5mo ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Establish the safety and tolerability profile(s) of the CDX-110 vaccination schedule in these patients. [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]
Assess humoral and cellular immune responses to CDX-110 vaccinations and explore the overall immunogenicity of the vaccine as well as any interactions with steroid dosing and maintenance temozolomide. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
Assess overall survival. [ Time Frame: indeterminate ] [ Designated as safety issue: No ]
