A randomized, double-blind, placebo-controlled multiple ascending dose study in hypertensive subjects on stable doses of at least three hypertensive drugs for at least 6 weeks prior to Screening. The study will consist of screening, PK-unit admittance, and safety follow up periods. Subjects will be randomized at a 6:2 ratio of either MANP or placebo and will be stratified by race in each dosage cohort. The entire first Cohort will be given the lowest dosage with subsequent cohorts progressing sequentially to the higher doses depending on safety and tolerability of the previous cohort. Endpoints not related to the safety reviews will be analyzed after the last patient last visit (LPLV).
