SPICE is the first, international, randomized, placebo-controlled, double-blind study to investigate the influence of the herbal drug Crataegus Special Extract WS 1442 (hawthorn leaves with flowers) on mortality of patients suffering from congestive heart failure. Background: In vitro and experimental animal studies have suggested the following pharmacological modes of action of standardized Crataegus extracts: (1) cAMP-independent positive inotropy; (2) peripheral and coronary vasodilation; (3) protection against ischemia-induced ventricular arrhythmias; (4) antioxidative properties; and (5) antiinflammatory effects. Study design: In this randomized, placebo-controlled, double-blind, international trial (approximately 120 investigational centers in seven European countries), up to 2300 patients with congestive heart failure, New York Heart Association class II and III and markedly impaired left ventricular function, will be enrolled and treated over a period of 24 months. During this time patients receive either two film-coated tablets of 450 mg of the Special Extract WS 1442 standardized to 84.3 mg of oligomeric procyanidines or matched placebo per day in addition to standard therapy for congestive heart failure, such as diuretics, digoxin or digitoxin, beta -adrenoceptor blockers and angiotensin-converting-enzyme inhibitors. The primary outcome variable is the combined endpoint of cardiac death, non-lethal myocardial infarction, and hospitalization due to progression of heart failure. Secondary outcome variables are total mortality, exercise duration, echocardiographic parameters, quality of life as well as pharmacoeconomic parameters. The first patient was included in October 1998. The trial is expected to be completed at the end of 2002. (C) European Society of Cardiology. All rights reserved.
