Clinical Trial: Bevacizumab and Lapatinib in Children With Recurrent or Refractory Ependymoma

Study Status: Completed
Recruit Status: Completed
Study Type: Interventional

Official Title: A Phase II Study of Bevacizumab and Lapatinib in Children With Recurrent or Refractory Ependymoma

Brief Summary: The goal of this clinical research study is to learn if the combination of Avastin (bevacizumab) and Tykerb (lapatinib) can help to control ependymoma in pediatric patients. The safety of this drug combination will also be studied.

Detailed Summary:

The Study Drugs:

Bevacizumab is designed to block the growth of blood vessels that supply nutrients necessary for tumor growth. This may prevent and/or slow down the growth of cancer cells.

Lapatinib is designed to prevent or slow down the growth of cancer cells by blocking proteins inside the cancer cells.

Study Drug Administration:

If you are found to be eligible to take part in this study, you will receive bevacizumab every 2 weeks while you are on study (2 times during each 4-week "study cycle"). The first time you receive the drug, it will be given by vein over 90 minutes. If this dose is well tolerated, you may receive future doses over 30 minutes.

You will take pills of lapatinib 2 times each day while you are on study. The pills should be taken at about the same time each day. You should not eat or drink anything except water for 1 hour before or 1 hour after you take the pills. If you miss a dose, do not take extra pills the next day to try and make up for the missed dose. You should report any missed pills or any trouble you may have with taking the pills to your study doctor.

You will be given a patient diary in which you must record what time you take lapatinib each time.

Study Visits:

At all study visits, you will be asked about any other drugs that you may be taking and about any side effects that you may be experiencing.

During Cycle 1 the following tests and procedures will be performed at least 1 time each week:

Primary endpoint is objective response rate, complete response plus partial response (CR+PR) sustained for at least four weeks. Complete Response (CR) - Complete disappearance on magnetic resonance imaging (MRI) of all enhancing tumor and mass effect, on a stable or decreasing dose of corticosteroids (or receiving only adrenal replacement doses), accompanied by a stable or improving neurologic examination and must be sustained for at least 4 weeks. If CSF was positive it must become negative. Partial Response (PR) - Greater than or equal to 50% reduction in tumor size by bi-dimensional measurement on a stable or decreasing dose of corticosteroids, accompanied by stable or improving neurologic examination and must be sustained for at least 4 weeks.
