Vatalanib in Treating Patients With Recurrent or Progressive Meningioma
RATIONALE: Vatalanib may stop the growth of tumor cells by blocking blood flow to the tumor and by blocking some of the enzymes needed for cell growth.
PURPOSE: This phase II trial is studying how well vatalanib works in treating patients with recurrent or progressive meningioma.
Brain and Central Nervous System Tumors
|Study Design:||Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||A Phase II Trial of PTK-787 in Recurrent or Progressive Meningiomas|
- Number of Patients Who DID NOT Experience Disease Progression or Death by 6 Months After Starting Treatment. [ Time Frame: From the date the first patient began treatment until the date the last patient has disease progression, becomes deceased, or completes 6 months of treatment ] [ Designated as safety issue: No ]Patients were assessed with imaging techniques (MRI) during screening/baseline and then every 2 months after starting treatment. Survival status and disease status were recorded. The number of patients who did not experience an event (defined as either death for any reason or progression of their disease) by 6 months after starting treatment were counted.
- Determine Efficacy (Radiographic and Clinical Improvement) [ Time Frame: At baseline, every 2 weeks for 2 months, then every 8 weeks while on treatment ] [ Designated as safety issue: No ]Efficacy will be assessed by MRI scan and neurological exam upon study entry, every 2 weeks for 2 months, then every 8 weeks while on treatment
- To Describe the Response Rate and Overall Survival in This Patient Population [ Time Frame: Every 2 months for up to 1 year after study treatment ] [ Designated as safety issue: No ]Response rate and overall survival will be assessed by MRI scan every 2 months while on study treatment and follow-up will be done at regularly scheduled office visits up to 1 year after discontinuation of study treatment.
- To Correlate the Response Rates With Expression of Certain Types of Genes [ Time Frame: At the end of study treatment ] [ Designated as safety issue: No ]Correlation of response rates with the expression of certain types of genes will be assessed by examining tissue samples taken from previous surgery and testing for certain genes
- To Determine the Safety of Vatalanib in Patients With Recurrent of Progressive Meningiomas [ Time Frame: Every week while on study treatment ] [ Designated as safety issue: Yes ]Safety of vatalanib will be assessed by labs being done weekly
- Number of Months Patients Survive After Being Treatment on the Study. [ Time Frame: From the date the first patient began treatment until the date the last patient became deceased. ] [ Designated as safety issue: No ]
- Develop Data Concerning Certain Genes That Cause Tumors to Grow New Blood Vessels [ Time Frame: MRI with MR Perfusion will be done before treatment and then every 2 months while on study treatment ] [ Designated as safety issue: No ]Data concerning certain genes that cause tumors to grow new blood vessels will be examined by MRI scan with MR Perfusion done before treatment and then every 2 months while on study treatment
- To Use the FACT BR Questionnaire to Measure Quality of Life [ Time Frame: At baseline and then every time an MRI is performed while on study treatment. ] [ Designated as safety issue: No ]FACT BR questionnaire will be used to measure quality of life at baseline and then every time an MRI scan is performed while on study treatment
|Study Start Date:||May 2006|
|Study Completion Date:||July 2013|
|Primary Completion Date:||November 2010 (Final data collection date for primary outcome measure)|
Patients will be treated with 500 mg of vatalanib, administered orally, twice a day for 28 days (1 cycle). Patients will start at a dose of 250 mg twice a day and increase by 250 mg per day every 7 days until 500 mg twice a day is reached.
Patients who are responding may remain on study treatment for 12 months.
- Determine the efficacy of vatalanib, in terms of radiographic improvement and clinical improvement, in patients with recurrent or progressive meningioma.
- Determine the 6-month progression-free survival of these patients.
- Describe the response rate and overall survival of these patients.
- Determine the safety of vatalanib in these patients.
- Correlate the response rates with expression of vascular endothelial growth factor, epidermal growth factor receptor, platelet-derived growth factor, and HER2.
- Develop exploratory data concerning surrogate markers of angiogenic activity in vivo using magnetic resonance perfusion.
OUTLINE: Patients receive oral vatalanib twice daily on days 1-28. Courses repeat every 28 days for 1 year in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed for 1 year.
PROJECTED ACCRUAL: A total of 25 patients will be accrued for this study.
