RE: timing of news release Great question. If you look back at the press releases on the RVX website, you will see some examples of press release/teleconference examples.
1) In 2009, they had a press release on a Friday (9/25) for a teleconference on a Tuesday (9/29) to discuss topline data of Phase 1b/2a clinical trial.
2)In 2010 when they annouced topline ASSERT data, they released a Monday press release (11/15) announcing a Wednesday conference call (11/17). Wednesday 11/17 was the AHA meeting presentation of ASSERT data, conference call, and press release of data.
3)In April 2012, when they announced their mechanism of action, they released a Thursday press release (4/19) for a Monday conference call (4/23).
.
So there is not really any precedence for top-line data and conference call discussing this data being done on the same day that they intially announce the upcoming conference call. Looks like at least 2 day gap is typical.
