Basel, September 24, 2012 - Phase III study results show that investigational RLX030 (serelaxin) reduced all-cause mortality in patients with acute heart failure (AHF). The six-month RELAX-AHF study shows that RLX030 reduces the number of deaths in patients with this disease, which has a higher mortality rate than most other cardiovascular diseases.
The study had two primary endpoints using different scales to measure reduction in dyspnea, only one of which reached statistical significance. Dyspnea, or shortness of breath, is the most common symptom of AHF. RLX030 was well tolerated in the study.
RELAX-AHF was a Phase III clinical trial to investigate the efficacy and safety of RLX030 for the treatment of AHF. It was a randomized, double-blind, placebo-controlled study involving 1,161 patients in 11 countries. In the study, RLX030 was given on admission to the hospital in the form of an intravenous infusion for up to 48 hours in addition to loop diuretics and other medicines and was compared to placebo on top of standard of care treatment for AHF,.
The study will be presented at the American Heart Association (AHA) congress in Los Angeles in November, 2012. Novartis will initiate discussions of the results of this single Phase III study with health authorities worldwide shortly.
Heart failure is a disease in which the heart is unable to supply enough blood to meet the body's needs,. Around half of all patients die within five years of diagnosis, particularly as a result of acute episodes in which their symptoms suddenly become worse and urgent hospital treatment is needed. Acute heart failure (AHF) places an enormous burden on healthcare systems and accounts for around two million hospitalizations each year in the EU and US.
RLX030 is the first in a new class of medicines and is a recombinant form of the human hormone relaxin-2 which occurs naturally in both men and women. In women, levels of relaxin-2 rise to support important physiological changes during pregnancy. Serelaxin acts by relaxing the blood vessels, leading to reduced stress on the heart and kidneys in both men and women.
The foregoing release contains forward-looking statements that can be identified by terminology such as "to be discussed," "will," or similar expressions, or by express or implied discussions regarding potential marketing submissions or approvals for RLX030 or regarding potential future revenues from RLX030. You should not place undue reliance on these statements. Such forward-looking statements reflect the current views of management regarding future events, and involve known and unknown risks, uncertainties and other factors that may cause actual results with RLX030 to be materially different from any future results, performance or achievements expressed or implied by such statements. There can be no guarantee that RLX030 will be submitted or approved for sale in any market. Nor can there be any guarantee that RLX030 will achieve any particular levels of revenue in the future. In particular, management's expectations regarding RLX030 could be affected by, among other things, unexpected clinical trial results, including unexpected new clinical data and unexpected additional analysis of existing clinical data; unexpected regulatory actions or delays or government regulation generally; competition in general; government, industry and general public pricing pressures; the company's ability to obtain or maintain patent or other proprietary intellectual property protection; unexpected manufacturing difficulties; the impact that the foregoing factors could have on the values attributed to the Novartis Group's assets and liabilities as recorded in the Group's consolidated balance sheet, and other risks and factors referred to in Novartis AG's current Form 20-F on file with the US Securities and Exchange Commission.
