Purpose: The objective of this study was to evaluate the efficacy and safety of the lercanidipine/valsartan combination compared with lercanidipine monotherapy in patients with hypertension.

Methods: Part 1 of this study was the randomized, multicenter, double-blind, parallel group, Phase III, 8-week clinical trial to compare superiority of lercanidipine 10 mg/valsartan 80 mg (L10/V80) and lercanidipine 10 mg/valsartan 160 mg (L10/V160) combinations with lercanidipine 10 mg (L10) monotherapy. At screening, hypertensive patients, whose diastolic blood pressure (DBP) was >90 mm Hg after 4 weeks with L10, were randomized to 3 groups of L10, L10/V80, and L10/V160. The primary end point was the change in the mean sitting DBP from baseline (week 0) after 8 weeks of therapy. Patients who were randomly assigned to L10/V160 and whose mean DBP was still ≥ 90 mm Hg in part 1 were enrolled to the up-titration extension study with lercanidipine 20 mg/valsartan 160 mg (L20/V160) (part 2).

Findings: Of 772 patients screened, 497 were randomized to 3 groups (166 in the L10 group, 168 in the L10/V80 group, and 163 in the L10/V160 group). Mean (SD) age was 55 (9.9) years, and male patients comprised 69%. The mean (SD) baseline systolic blood pressure (SBP)/DBP were 148.4 (15.1)/94.3 (9.5) mm Hg. No significant differences were found between groups in baseline characteristics except the percentages of previous history of antihypertensive medication. The primary end points, the changes of mean (SD) DBP at week 8 from the baseline were -2.0 (8.8) mm Hg in the L10 group, -6.7 (8.5) mm Hg in L10/V80 group, and -8.1 (8.4) mm Hg in L10/V160 group. The adjusted mean difference between the combination groups and the L10 monotherapy group was -4.6 mm Hg (95% CI, -6.5 to -2.6; P < 0.001) in the L10/V80 group and -5.9 mm Hg (95% CI, -7.9 to -4.0, P < 0.001) in the L10/V160 group, which had significantly greater efficacy in BP lowering. A total of 74 patients were enrolled in the part 2 extension study. Changes of mean (SD) DBP and SBP from week 8 to week 12 and week 16 were -5.6 (7.9)/-8.0 (12.0) mm Hg and -5.5 (7.0)/-8.5 (11.3) mm Hg, respectively. For evaluation of the safety profile, the frequencies of adverse events between groups were also not significantly different. The most frequently reported adverse events were headache (6 cases, 20.7%) in the L10 group, dizziness (8 cases, 16.3%) in L10/V80 group, and nasopharyngitis (3 cases, 9.4%) in L10/V160 group, and the incidences of adverse events were not different between groups.

Implications: Treatment of L10/V80 or L10/V160 combination therapy resulted in significantly greater BP lowering compared with L10 monotherapy. Moreover, the L20/V160 high dose combination had additional BP lowering effect compared with nonresponders with the L10/V160 combination. ClinicalTrials.gov: NCT01928628.
