Polycystic Ovary Syndrome and Liraglutide as Add-on Therapy on Metformin

July 26, 2013 updated by: Andrej Janez, University Medical Centre Ljubljana

Short-term Combined Treatment With Liraglutide and Metformin Leads to Significant Weight Loss in Obese Women With Polycystic Ovary Syndrome and Previous Poor Response to Metformin

The purpose of this study was to determine whether combined treatment with liraglutide and metformin is more effective than liraglutide or metformin as monotherapy in the treatment of obese women with polycystic ovary syndrome (PCOS) who had been previously poor responders regarding weight reduction on metformin monotherapy. We anticipated greater changes in body weight in patients on combined treatment than in those on monotherapy with liraglutide or metformin.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
