Brief Summary

This integrated assessment consists of two studies, 603A and 603B, to be carried out sequentially in a common study population. Participating subjects informed of the trial design and their consent to participate in both studies were to be obtained in a single consent form. Approximately 680 male or female adult subjects were to be enrolled.

Detailed Description

THR-1442-C-603 is an integrated assessment of the potential utility of bexagliflozin tablets, 20 mg for the treatment of essential hypertension. It is composed of two studies, 603A and 603B, measuring effects in a common population.

603A was a multicenter double-blind parallel group placebo-controlled study conducted to determine the placebo-adjusted change from baseline to week 12 in the mean ambulatory systolic blood pressure (SBP) of approximately 680 subjects considered generally representative of the adult hypertensive population in the United States. Secondary endpoints included the placebo-adjusted change from baseline to week 12 of the mean office seated systolic blood pressure, the change to week 12 of the mean ambulatory and mean office seated diastolic blood pressure, the proportion of subjects achieving prespecified goals for absolute systolic and diastolic blood pressure as well as prespecified goals for reduction in systolic and diastolic blood pressure, measured by ambulatory and seated office measurement methodology.

A603B was a multicenter double-blind parallel group placebo-controlled randomized withdrawal study conducted to determine the durability of the antihypertensive effect of bexagliflozin tablets, 20 mg, in a population not pre-selected for existing diabetes. All subjects entered a 12 week run-in period during which they self-administered open label bexagliflozin tablets, 20 mg once daily. At week 12 a baseline ambulatory blood pressure monitoring (ABPM) measurement was made, and the subjects were randomized one to one to receive either bexagliflozin tablets, 20 mg or bexagliflozin tablets, placebo. After a 12 week treatment period a second ABPM measurement was made. The primary endpoint was the intergroup difference in the change from baseline in the mean SBP.
