DBL is basically when no more data can be collected/entered into the database. Once locked, it is then released to Resverlogix and the BETonMACE Clinical Investigators. IMO, it is not a material events.....I haven't seen other companies new releasing DBLs. As stated in the April 18th news release:

"Database Lock (DBL) will occur after the last patient’s final visit and the last query is resolved. Approximately two weeks after DBL, the primary endpoint and additional secondary and exploratory endpoints are expected to be announced."
