Takeda Pharmaceutical Company Limited (Takeda) announced that Takeda Global Research & Development Center, Inc. US, submitted a New Drug Application (NDA) to the US Food and Drug Administration (FDA) for an investigational fixed-dose combination of azilsartan medoxomil plus chlorthalidone (CLD) for the treatment of hypertension, or high blood pressure. Discovered by Takeda, azilsartan medoxomil is an angiotensin II receptor blocker (ARB) that lowers blood pressure by blocking the action of angiotensin II, a vasopressor hormone. Chlorthalidone is a long-acting oral thiazide-like diuretic used in the treatment of hypertension. The NDA submission was supported by four phase 3 clinical trials involving more than 4,000 patients with hypertension.

“Millions of patients with hypertension do not have their condition under control,” said Darryl Sleep, M.D., vice president, clinical science, Takeda Global Research & Development Center, Inc. US. “We believe this compound, the first in the US to combine an ARB with chlorthalidone, could potentially provide an important new treatment option for patients with hypertension and the health care providers who manage them.”

In a phase 3 clinical trial, azilsartan medoxomil (20 mg/day, 40 mg/day and 80 mg/day), combined in a fixed-dose with CLD (12.5 mg/day and 25 mg/day), was studied versus azilsartan medoxomil and CLD monotherapies. In other studies, the fixed-dose combination of azilsartan medoxomil plus CLD was compared to azilsartan medoxomil coadministered with hydrochlorothiazide (HCTZ), another diuretic, and with a fixed-dose combination of olmesartan medoxomil and HCTZ.

Results from a phase 3 clinical trial of the fixed-dose combination of azilsartan medoxomil plus CLD were previously presented at the American Society of Hypertension, Inc. (ASH), 25th Annual Scientific Meeting and Exposition in New York in May 2010. The 10-week, randomized, double-blind study compared the effect of CLD and HCTZ, both in combination with azilsartan medoxomil, on systolic and diastolic blood pressure (SBP, DBP) by clinic blood pressure measurement and by ambulatory blood pressure monitoring (ABPM) in 609 patients with hypertension.

Developed by Takeda, azilsartan medoxomil plus chlorthalidone is an investigational fixed-dose combination for the treatment of hypertension, or high blood pressure. The fixed-dose combination of azilsartan medoxomil plus chlorthalidone contains two medications, azilsartan medoxomil, an angiotensin II receptor blocker, and chlorthalidone, a long-acting thiazide-like diuretic used in the treatment of hypertension. The most commonly reported adverse drug reactions occurring in at least two percent of azilsartan medoxomil plus CLD-treated patients at the recommended doses and greater than azilsartan medoxomil or chlorthalidone monotherapies were increased blood creatinine (11%), dizziness (8.2%), blood uric acid (3.8%), blood urea (2.8%), and fatigue (2.5%). Most elevations of creatinine were transient and were generally associated with large blood pressure reductions.
