Clinic and ambulatory blood pressure lowering effect of aliskiren/amlodipine/hydrochlorothiazide combination in patients with moderate-to-severe hypertension
Bibliographic record
Abstract
OBJECTIVES: To evaluate the clinic and ambulatory blood pressure (BP)-lowering efficacy and safety of an aliskiren/amlodipine/hydrochlorothiazide (HCT) triple combination compared with the component dual combinations, in patients with moderate-to-severe hypertension. METHODS: This 8-week, double-blind, randomized, active-controlled study, after 1-4 weeks single-blind placebo run-in period, randomized 1191 patients to receive once-daily aliskiren/amlodipine 150/5 mg (n = 287), aliskiren/HCT 150/12.5 mg (n = 298), amlodipine/HCT 5/12.5 mg (n = 296), or aliskiren/amlodipine/HCT 150/5/12.5 mg (up-titrated from aliskiren/HCT 150/12.5 mg after initial 3 days) (n = 310) for 4 weeks, followed by forced titration to double the initial dose for the next 4 weeks. RESULTS: Baseline mean sitting SBP and DBP (msSBP/msDBP) was comparable among treatment groups. The aliskiren/amlodipine/HCT combination resulted in significant least squares mean reduction in msSBP/msDBP from baseline to endpoints (week 4, -30.7/-15.9 mmHg; week 8, -37.9/-20.6 mmHg), superior (P < 0.001) to each of the dual combinations. The triple combination was associated with -27.8 mmHg reduction in msSBP at week 2, significantly better than the dual combinations (P < 0.05). Significantly greater mean SBP/DBP-lowering effect for triple vs. dual combinations was also demonstrated through 24-h, daytime, and night-time ambulatory BP measurements. Significantly greater (P < 0.001) BP control (msSBP/msDBP < 140/90 mmHg) was achieved with triple combination in patients with moderate-to-severe (62.3%) and severe (57.5%) hypertension. CONCLUSION: Aliskiren/amlodipine/HCT at 150/5/12.5 mg (week 4) and 300/10/25 mg (week 8) provided statistically superior reductions in msSBP/msDBP and greater BP control rates vs. the dual combinations, and was well tolerated. The improved efficacy of BP reduction was evident within 2 weeks of initiating triple therapy even at low dose.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
