Can A Bunch Of Doctors Keep An $8 Billion Secret? Not On Twitter

In New Orleans Monday, a major medical organization attempted a feat perhaps as hard as treating the disease doctors were there to discuss. They asked a packed convention hall of attendees not to tweet the confidential, market-moving data they had flown in to see.

It didn’t work.

In an unusual arrangement, the American Diabetes Association let hundreds, if not thousands, of in-person attendees see new data on Novo Nordisk A/S’s blockbuster diabetes treatment Victoza more than an hour before its official release to the public and the markets. That’s atypical for such sensitive data, which are usually shared only with journalists and researchers who have agreed to abide by strict terms, under threat of losing future access.
