Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Drugs - carboplatin
Treatment: Drugs - lomustine
Treatment: Drugs - procarbazine hydrochloride
Treatment: Drugs - thioguanine
Treatment: Drugs - vincristine sulfate

Experimental: Regimen A (CV Chemotherapy) - Induction will consist of 10 weeks of therapy (carboplatin, vincristine sulfate),followed by 2 weeks without chemotherapy. Induction should only be interrupted in the event of grade 3 neurotoxicity, grade 2 renal toxicity, grade 4 hematologic toxicity, or tumor progression. Maintenance-Four Courses (2 cycles/course) commences on Day 84 (week 12) of Induction or when peripheral counts recover with ANC >1,000/$L and platelet count >100,000/$L. Each cycle will consist of 4 weekly doses of carboplatin, three weekly doses of vincristine sulfate (given concomitantly with the first 3 weeks of carboplatin), followed by two weeks of rest for a total of 6 weeks. Maintenance will continue for a total of 8 cycles.

Experimental: Regimen B (TPCV Chemotherapy) - Each cycle of chemotherapy consists of 4 days of oral chemotherapy (Thioguanine, procarbazine hydrochloride, Lomustine and Vincristine sulfate beginning Day 0, followed by vincristine sulfate IV on Days 14 and 28. The cycle is repeated every 6 weeks (42 days). A total of 8 cycles will be given.

Summary
Brief summary
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so
they stop growing or die. Combining more than one drug may kill more tumor cells.

PURPOSE: This randomized phase III trial is studying two different combination chemotherapy
regimens and comparing how well they work in treating children with low-grade astrocytomas or
other residual tumors of the brain.
