Basel, 21 May 2007-Tekturna, approved in the US in March 2007, represents the first new type of medicine for treating high blood pressure in more than a decade .

New data show Tekturna, when used alone or in combination with the diuretic hydrochlorothiazide, delivers significant blood pressure lowering over one-year period[1]

Single-tablet combination therapies could help people with high blood pressure better comply with treatment by reducing "pill burden"[2]

About 70% of high blood pressure patients still not reaching their treatment goals and many require two or more medicines[ ;3],[4]

Basel, May 21, 2007 - A single-tablet combination of two high blood pressure medicines - the recently approved direct renin inhibitor Tekturna® (aliskiren) and the widely-used diuretic hydrochlorothiazide - has been submitted for US regulatory approval.

Tekturna HCT®[*] represents the first regulatory submission for a single-tablet combination therapy involving Tekturna, which is the first new type of high blood pressure medicine in more than a decade. Tekturna was approved by the US Food and Drug Administration in March 2007, while a decision on European Union approval is expected by the end of 2007.

Single-tablet combination therapies like Tekturna HCT may make blood pressure management easier for people by reducing the number of pills they take daily. High blood pressure affects one in four adults around the world, and an estimated 70% of these patients do not currently reach their target blood pressure lev el[3]. In fact, most patients require two or more medicines to reach their goal[4].

"Several studies show that many adults with high blood pressure remain uncontrolled despite treatment. This is because too often physicians fail to treat aggressively enough," said Dr. Alan Gradman, Chief of the Division of Cardiovascular Diseases at the Western Pennsylvania Hospital in Pittsburgh. "A tablet combining the first direct renin inhibitor and a diuretic would give doctors an important new treatment option to help patients reach their treatment goals."

New clinical data involving 1,625 patients, presented today at the American Society of Hypertension meeting in Chicago, showed that Tekturna produced significant blood pressure lowering effects over a one-year period. These results were seen both alone and in combination with hydroclorothiazide[1]. Tekturna was generally well tolerated, with the most common side effects being bronchitis (6.1%), nasopharyn gitis (5.1%) and headache (3.5%)[1].

Hydrochlorothiazide is a diuretic, commonly known as a "water pill", that helps the body get rid of unneeded water and salt through urine. It was among the first high blood pressure treatments, since removing excess fluid makes it easier for the heart to pump and control blood pressure.

The submission of Tekturna HCT was based on data from seven clinical trials involving more than 6,200 patients[5], including the data presented at the ASH meeting. Submissions were made for four different dosage combinations of Tekturna and hydrochlorothiazide: 150/12.5 mg tablets, 150/25 mg tablets, 300/12.5 mg tablets and 300/25 mg tablets.

Tekturna, developed in collaboration with Speedel, is the first approved direct renin inhibitor and received US approval based on results of an extensive clinical trial program showing significant blood pressure reductions for a full 24 hours. It is known as Rasilez® outside the US. Tekturna should not be used by women who are pregnant or plan to become pregnant.

"Tekturna HCT represents an initial success in our efforts to explore the benefits of combining this innovative medicine with other complementary high blood pressure agents. We will continue to assess other combinations th at would be of use for patients and physicians," said Dr. James Shannon, Global Head of Development at Novartis Pharma AG.
