The Merck files: a series

April 13, 2022March 7, 2022 by Montaigne

Selected documents from Propecia litigation were released by court order in 2021. This series walks through these documents, revealing Merck’s strategy for discounting safety concerns arising from clinical trials and adverse event reports. The collection is divided into three parts:

1. An inside look at the development of Propecia (1994–2001)
2. Merck responds to regulatory concerns (2006–2009)
3. Propecia lawsuits (2011–2020)

The source documents are available thanks to the efforts of Reuters Investigates, and hosted on the website of the Post-Finasteride Syndrome Foundation.
