Trial Outcomes & Findings for VEGF Trap in Treating Patients With Recurrent Malignant Gliomas That Did Not Respond to Temozolomide (NCT NCT00369590)

NCT ID: NCT00369590

Last Updated: 2015-10-02

Results Overview

This design yields 85% power to detect a true 30% 6-month PFS rate, while maintaining .91 probability of rejecting for a true 15% 6-month PFS rate. pts had MRIs at screening and at the 3rd and 5th cycles then every 8 weeks until progression. Response determined by modified MacDonald Criteria Complete Response (CR): Complete disappearance of all measurable and evaluable disease, no new lesions. no steroids Partial Response (PR): Greater than or equal to 50% decrease under baseline in the sum of products of perpendicular diameters of all measurable lesions. No progression of evaluable lesions. no new lesions. steroid dose no \> than maximum dose used in first 8 weeks of treatment. Stable: Does not qualify for CR, PR, or progression steroid dose no \> than maximum dose used in first 8 weeks of treatment. Progression: 25% increase in the sum of products of all measurable lesions over smallest sum observed (over baseline if no increase) Clear clinical worsening.

PRIMARY outcome

Timeframe: 6 months

Population: pts not known to be progression free at time of the 6-month scan (24weeks) were considered to experienced treatment failure. If at least 10pts (24%) are progression-frree at 6months (GBM) the agent will be considered promising for futher study. The 3 pts in Arm 2 were treated at 2nd recurrence and were excluded from final efficacy analysis
