your problem is completely unrelated to iTextSharp. unless you explicitly call 
Response.End(), the .aspx page will append HTML to the stream.

try this test:

[1] instead of opening the PDF save it to disk.

[2] open the PDF with a text editor

you'll see the HTML of your .aspx page. it **shouldn't** be there.

in most cases you should be using a HTTP Handler to send PDF anyway:

http://msdn.microsoft.com/en-us/library/system.web.ihttphandler.aspx

lower overhead than a .aspx page
