This study assessed the clinical benefit of adding chlorthalidone to a fixed-dose combination of valsartan and amlodipine to form KDF1901, a triple combination therapy. The study included 286 patients with essential hypertension who did not reach target blood pressure after a 4-week run-in period with valsartan/amlodipine (80/5 mg). They were randomized 1:1 to receive either KDF1901 (160/10/25 mg) or valsartan/amlodipine (160/10 mg) for 8 weeks. At week 8, the KDF1901 group showed significantly greater reductions in MSSBP (-21.2 ± 9.3 mmHg vs. -15.4 ± 8.7 mmHg, p\<0.001) and MSDBP (-12.2 ± 6.5 mmHg vs. -8.6 ± 6.2 mmHg, p\<0.001) than the dual therapy group. Blood pressure normalization and response rates were also significantly higher with KDF1901. Subgroup analyses revealed consistent efficacy in elderly and diabetic patients. The incidence of TEAEs was similar between groups, and most adverse events were mild and not drug-related. These results suggest the potential clinical utility of chlorthalidone-based triple therapy in high-risk hypertensive patients.2c:T108c,Inclusion Criteria: 1.
