You probably need the re.MULTILINE flag.  This worked for me

 >>> import re
 >>> pat = re.compile(r"^\*\s*\n(^\*\s*\n)+", re.MULTILINE)
 >>> text = """/**
... *
... * Project:      MyProject
... *
... *
... *
... *
... *
... *
... *
... * Description:

... *    This file contains the some code.
... *
... * Public Functions:
... *
... *     function_1
... *     function_2
... *
... * Private Functions:
... *
... *    None.
... *
... *
... * Notes:
... """
 >>> print pat.sub("*\n", text)
/**
*
* Project:      MyProject
*
* Description:
*
*    This file contains the some code.

* Public Functions:
