I seem to remember, from my early search for answers, the original New Drug Application (20-180) Approval Package pdfs were available from the FDA web-site. It now appears that this original document is now not available.
If anyone has this pdf document please contact me. I reached a sticking point in my current research, as certain official documents for Propecia ™ reference the original NDA 20-180 Approval Package. If indeed access to these documents have been made limited to the public there must be someone who has accessed them and downloaded them a few years back.
Additionally, this also applies to anyone who possesses a copy of the following document: Stoner E (1992) The clinical effects of a 5 alpha-reductase inhibitor, finasteride, on benign prostatic hyperplasia. The Finasteride Study Group. J. Urol. 147(5): 1298-1302
Please reach-out if you have these documents.
