Clinical Trial Summary

SPH3127 tablet is a of renin inhibitor. It is expected to be a new drug for essential hypertension. This is a phase IIa trial which designed to evaluate its efficacy and safety on treating mild-moderate essential hypertension patients.

Description:

This is a dose finding trial. Totally 120 mild-moderate essential hypertension patients will be enrolled. All the patients will be randomized (1:1:1:1) into four groups (SPH3127 50mg, SPH3127 100mg, SPH3127 200mg and placebo).

The trial has three phases: the screening phase, the leading phase and the treating phase.

The primary endpoints are the changes of DBP and SBP compared to the baseline after 8 weeks of treatment.

All the adverse events are required to be collected for safety analyzing.
