CNS 18 - 43 
POSSIBLE BENEFITS 
We hope that this treatment can make the tumor smaller, but we do not know this. What we 
learn from this study may help other patients in the future. 
ALTERNATIVE TREATMENTS 
There are no standard treatments that are likely to help at this point. There may be other 
research treatments that could be used and your doctor will discuss this with you. You may 
also prefer not to have any more treatment. 
STATEMENT OF UNDERSTANDING 
Information about your treatment will be known only by the hospital staff who need to know. 
Doctors working with this gene therapy in other hospitals will also need to know about your 
treatment. We will not discuss it with anybody else without asking you first. You have the 
right to ask any questions you want and they will be answered. You have read this form, or 
had it read to you, and discussed it with your parents and the doctor (Dr. 
) caring for you. Before you signed this form, you had all your 
questions answered. 
If you have any other questions, you can ask your doctor or other people caring for you at 
any time.
