SU-101 Compared With Procarbazine in Treating Patients With Glioblastoma Multiforme

Basic Trial Information

Phase Type Status Age Sponsor Protocol IDs Phase III Treatment Completed 18 and over Pharmaceutical / Industry SUGEN-SU101.015 MSKCC-98020, UCLA-HSPC-980105201, NCT00003293

Objectives

I.  Compare the median survival of patients with glioblastoma multiforme in 
first relapse treated with intravenous leflunomide (SU101) administered as a 
loading dose with weekly maintenance therapy versus oral, single-agent 
procarbazine administered daily for 28 days every 56 days.

II.  Compare the median time to progression for these regimens in these 
patients.

III.  Assess the objective response of these patients.

IV.  Assess the safety of SU101 given on this schedule.

V.  Describe the health-related quality of life of these patients.

Outline

This is a randomized, open label, multicenter study.  Patients are stratified 
according to performance status (Karnofsky 60-80% vs 90-100%), age (less than 
50 vs 50 and over), and time from initial diagnosis to recurrence (6 months or 
greater vs less than 6 months).

Patients are randomized to one of two treatment arms.

Arm I: Patients receive leflunomide (SU101) IV over 6 hours daily on days 1-4, 
again 4-8 days later, and weekly thereafter for a total of 4 loading dose 
infusions and six maintenance infusions in course 1.  Patients receive 7 
weekly maintenance infusions of SU101 in courses thereafter.  Treatment 
repeats every 8 weeks.

Arm II: Patients receive procarbazine orally once or twice daily for 4 weeks. 
Treatment is repeated every 8 weeks.

All patients complete a health-related quality-of-life questionnaire every 8 
weeks and at study withdrawal.

Treatment courses continue up to a maximum of 1 year in the absence of 
unacceptable toxicity or disease progression.

Patients are followed every 2 months, beginning 30 days after study completion.
