Miscellaneous annotations

Indications / trials

ChEMBL indication annotations are just the trials conducted, regardless of their result. This results in some phase 3 annotations that are inconsistent with the actual approvals. The DrugBank search is better and should include almost everything that the ChEMBL search does. There’s also a DrugBank clinical trial search (db_trial) that should be more equivalent to the ChEMBL one.
