UPDATE 1-CombinatoRx's diabetes drug meets trial goal, shares up

* Drug meets primary endpoint in mid-stage trial

* Shares rise 39 pct before the bell

May 27 (Reuters) - CombinatoRx Inc CRXX.O said its anti-diabetic treatment met its primary goal in a mid-stage trial, sending the biopharmaceutical company's shares up 39 percent in pre-market trade.

The primary endpoint of the study found the drug, a combination of bezafibrate and diflunisal, performed significantly better than bezafibrate in reducing fasting plasma glucose and showed a positive trend in other efficacy measures, the company said.

The study, which enrolled 120 people with moderate to severe diabetes, tested the drug as an add-on to metformin therapy in Type 2 diabetes.

The drug, code named CRx-401, is an insulin sensitizer designed to provide anti-diabetic activity without promoting weight gain.

Shares of the company were up 39 percent at 96 cents before the bell. They closed at 69 cents Tuesday on Nasdaq.
