Where are the phase IIb results for Bimatoprost?

[outbulk]

According to clinicaltrials.gov they finished the study in November 2014 and should have the final results in January 2015:

It's May 2015 now, shouldn't they have already published the results? Or do pharma companies keep the data for themselves?

Would like to know what concentration of bimatoprost was safe and effective, so we can make our own.
