Yet another "promising" novel antidepressant has failed to actually treat depression.
That's not an uncommon occurrence these days, but this time, the paper reporting the findings is almost as rubbish as the drug: Translational evaluation of JNJ-18038683, a 5-HT7 receptor antagonist, on REM sleep and in major depressive disorder

It didn't - in a multicentre randomized controlled trial of 230 depressed people, it had absolutely no benefits over placebo. A popular existing drug, citalopram, failed as well:
