Conditions brain and central nervous system tumors, sarcoma
Treatment vatalanib
Phase phase 2
Sponsor Northwestern University
Collaborator Novartis
Start date May 2006
End date April 2014
Trial size 25 participants
Trial identifier NCT00348790, NU 05C4, STU00005338


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.

Study Design

Allocation non-randomized
Endpoint classification safety/efficacy study
Intervention model single group assignment
Masking open label
Primary purpose treatment
vatalanib PTK787
Patients will be given 500 mg twice a day (4 tablets) of PTK-787 daily for 28 days (1 cycle) by mouth. 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.

Primary Outcomes

To determine the 6 month progression free survival
time frame: MRI with MR Perfusion (optional) will be done before treatment and then every 2 months while on study treatment

Secondary Outcomes

Determine Efficacy (radiographic and clinical improvement)
time frame: At baseline, 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
To correlate the response rates with expression of certain types of genes
time frame: At the end of study treatment
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
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.
To determine the safety of vatalanib in patients with recurrent of progressive meningiomas
time frame: Every week while on study treatment

Additional Information

Official title A Phase II Trial of PTK-787 in Recurrent or Progressive Meningiomas
Principal investigator Jeffrey J. Raizer, MD
Description OBJECTIVES: Primary - Determine the efficacy of vatalanib, in terms of radiographic improvement and clinical improvement, in patients with recurrent or progressive meningioma. Secondary - 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.
