LCZ696

Описание

LCZ696 is a dual angiotensin II receptor antagonist and neprilysin inhibitor that is a combination of the nonpeptide angiotensin II receptor antagonist valsartan and AHU377 , a prodrug of LBQ657 , which is an inhibitor of the zinc metallopeptidase neprilysin., LCZ696 (2-60 mg/kg) induces a dose-dependent decrease in mean arterial pressure in rats expressing human renin and angiotensinogen, a double-transgenic model for angiotensin II-dependent hypertension. Formulations containing LCZ696 are under clinical investigation for the treatment of mild to moderate hypertension and chronic heart failure.

Механизм действия

LCZ696 is a molecule that combines the moieties of valsartan and sacubitril (the neprilysin inhibitor) in a single substance. By inhibiting neprilysin, the degradation of natriuretic peptides, bradykinin, and other peptides is slowed. Hence, high circulating levels of natriuretic peptides enhance diuresis , natriuresis, myocardial relaxation, and anti-remodelling, on top of the ARB effects of valsartan.

Клиническое использование

LCZ696 (Novartis Pharmaceuticals), a first-in-class inhibitor of dualacting angiotensin-2 type-I receptor and neprilysin inhibitors, was developed as a molecule composed of molecular moieties of valsartan and neprilysin inhibitor prodrug AHU377 in a 1:1 ratio. Several phase 2 randomised clinical trials have been done or are underway in patients with hypertension. In a proof-of-concept randomised trial, LCZ696 was compared with valsartan in 1328 patients with mild-to-moderate hypertension, and provided fully additive reduction of blood pressure. No cases of angio-oedema were reported in the 8 week treatment period. This tolerance should be confirmed, particularly in black patients, for whom omapatrilat resulted in a higher occurrence of angio-oedema than in white patients. Indeed, in the proof-of-concept trial only about 8% of patients were black.
