Efficacy and safety of 30-mg fimasartan for the treatment of patients with mild to moderate hypertension: an 8-week, multicenter, randomized, double-blind, phase III clinical study.
Abstract | PURPOSE: METHODS: In this randomized trial, 293 patients (219 men; mean age, 54.24 [9.77] years) with mild to moderate hypertension were enrolled. After randomization to receive 30-mg fimasartan (n = 115), placebo (n = 117), or 80-mg valsartan (n = 61), the treatment dose was kept constant without dose escalation for 8 weeks. The primary end point was improvement in sitting diastolic blood pressure (SiDBP) from baseline to 8 weeks that was compared between treatments with low-dose fimasartan and placebo. The secondary end point was the overall efficacy and safety of low-dose fimasartan compared with that of placebo or valsartan. FINDINGS: At week 8, SiDBP changed by -9.93 (8.86) mm Hg in the fimasartan group and by -2.08 (9.47) mm Hg in the placebo group, which indicated significant antihypertensive efficacy (P < 0.0001). Efficacy was shown at week 4 as measured by SiDBP (-9.96 [7.73] vs -2.27 [7.85] mm Hg; P < 0.0001) or sitting systolic blood pressure (SiSBP) (-16.18 [14.44] vs -1.95 [13.48] mmHg; P < 0.0001) and at week 8 as determined by SiSBP (-15.35 [16.63] vs -2.30 [14.91] mm Hg; P < 0.0001). The fimasartan group exhibited more potent antihypertensive efficacy than the valsartan group both at week 4 (SiDBP, -9.96 [7.73] vs -6.53 [9.58] mm Hg [P = 0.0123]; SiSBP, -16.18 [14.4] vs -7.65 [12.89] mm Hg [P = 0.0002]) and at week 8 (SiDBP, -9.93 [8.86] vs -5.47 [8.96] mm Hg [P = 0.0021]; SiSBP, -15.35 [16.63] vs -7.49 [13.68] mm Hg [P = 0.0021]). Most treatment-emergent adverse events (TEAEs) were mild (89 of 95), and there were no serious TEAEs. The incidence of TEAEs was 19.1% in the fimasartan group, 22.6% in the placebo group, and 13.6% in the valsartan group, with no significant differences. IMPLICATIONS: Low-dose fimasartan (30 mg) was well tolerated during the study period with no significant TEAEs. Low-dose fimasartan had an effective blood pressure-lowering effect that was greater than that of 80-mg valsartan in patients with mild to moderate hypertension.
