Kala Pharma posts mixed results from dry eye disease drug studies

Dec 28 (Reuters) - Kala Pharmaceuticals Inc on Friday reported mixed results from two late-stage trials testing its drug to provide temporary relief from the signs and symptoms of dry eye disease.

The drug, KPI-121, met the main goals of reducing redness and discomfort in the eye in one trial, but failed to show statistical significance on a scale that tested patients' eyes using a corneal staining technique.

The second trial met the main goal of reducing a sign of dry eye, but failed another main goal of reducing discomfort in the eye, a symptom of the disorder.
