Hi:
Here are just a few of the BOOKS on the subject (from SAS publications and Amazon.com)
SAS Programming in the Pharmaceutical Industry (Paperback)
by Jack Shostak
Validating Clinical Trial Data Reporting with SAS
by Carol I. Matthews and Brian C. Shilling
Analysis of Clinical Trials Using SAS: A Practical Guide
by Alex Dmitrienko, Geert Molenberghs, Christy Chuang-Stein, and Walter Offen
Perhaps they will be useful. There is also a specialized user group called "PharmaSUG" that meets every year.

You can search this web site for papers which were submitted to PharmaSUG and other user groups:
