Some studies suggested that the enantiomer they chose was slightly better at driving the effect people thought was causing the anti-depressive effect. Unfortunately, newer studies suggest that 1) that effect isn't responsible for the anti-depressive effect and 2) the enantiomer they chose doesn't seem to be as good as normal ketamine. Too soon to say, but early signs suggest this may have all been a fantastically expensive mistake. :(
