SPP100 (tekturna/rasilez) Reduces Left Ventricular Hypertrophy

- Latest study reveals further potential benefits of renin inhibitor in heart disease -

BASEL, Switzerland and BRIDGEWATER NJ, 1 April 2008 - Speedel (SWX: SPPN) today welcomed promising results from the latest SPP100 (Tekturna/Rasilez[1]) surrogate marker clinical trial which were announced by Novartis and presented in a late-breaking session at the American College of Cardiology meeting in Chicago.

The study results[2] show that SPP100, the first-in-class direct renin inhibitor, has shown clinically meaningful reductions in left ventricular hypertrophy, a proven predictor of heart disease, that are comparable to those seen with the current standard-of-care treatment. Left ventricular hypertrophy (LVH) is an abnormal thickening of the heart muscle and often results from high blood pressure. It affects nearly a third of all patients with high blood pressure and decreases the heart's ability to work efficiently - more than doubling a patient's risk of premature cardiovascular events or death[3].

Dr Chris Jensen, Head of Scientific Affairs, said: This data is yet another important step forward in demonstrating the full potential of SPP100 to treat both hypertension and its consequences, which so often lead to debilitating or fatal illness. As the data from Novartis' ongoing studies are published over the next few years we believe that clinicians will become increasingly convinced of the potential for SPP100 to benefit patients in ways that go beyond other types of drugs.

ALLAY study results The ALLAY (ALiskiren Left ventricular Assessment of hypertrophY) 36-week study treated 460 patients with SPP100, losartan or a combination of the two. Results showed that treatment with SPP100 alone reduced LVH as effectively as the angiotensin receptor blocker (ARB) losartan (-5.4% vs -4.7% respectively) after nine months of therapy, despite patients having very well-controlled baseline blood pressure. The combination of both medicines achieved a numerically greater reduction in LVH than losartan alone, but the result was not statistically significant. Alone and in combination, SPP100 was well-tolerated[2].

The ALLAY study is the latest trial in Novartis' ASPIRE HIGHER programme to highlight the organ protection potential of SPP100, the first new kind of high blood pressure treatment in more than a decade. ASPIRE HIGHER is the largest ongoing cardio-renal outcomes programme and involves more than 35,000 patients in 14 trials, including three new mega-trials.

SPP100 was approved by the US Food and Drug Administration (FDA) in the US in March 2007 under the trade name Tekturna and by the European Union under the name Rasilez in August 2007 to treat hypertension both as monotherapy and in combination with other anti-hypertensives. Novartis announced in July 2007 that it was also approved in Switzerland and in January 2008 that the FDA had approved it in combination with a diuretic to treat hypertension. Speedel successfully developed SPP100 through Phase I and II clinical trials before Novartis exercised its license-back option in 2002. Other studies[4],[5], including AVOID and ALOFT, have highlighted the protective potential of SPP100 against heart and kidney diseases.

About SPP100 (aliskiren, Tekturna/Rasilez) SPP100 (aliskiren, Tekturna/Rasilez) is the first-in-class oral direct renin inhibitor. The development of SPP100 is the result of over 20 years of research on renin. Renin is the rate-limiting enzyme at the top of the Renin Angiotensin System (RAS), one of the key regulators of blood pressure. The RAS is a cascade, starting with renin, leading to angiotensin I and finally to angiotensin II. Angiotensin-converting enzyme inhibitors (ACE-Is) and angiotensin II receptor antagonists (ARBs) have been developed to block this system "down stream" and have shown clinical efficacy in patients with hypertension and other cardiovascular diseases. By inhibiting renin at the top of the RAS, SPP100 decreases the system's activity, as measured by plasma renin activity (PRA). Lowering PRA is believed to be very important in end-organ protection (e.g. heart and kidney). PRA is an independent risk factor and direct surrogate marker for several cardio-renal diseases, such as myocardial infarction and chronic renal disease. Direct renin inhibitors lower PRA whereas most current leading anti-hypertensive drug classes such as ACE-Is and ARBs increase PRA levels.

Speedel believes that it is the first company to establish successfully a clinical proof of concept in Phase II and to have developed and filed for patent protection a commercially viable manufacturing process for a renin inhibitor, an area of industry research for over 20 years. In a Phase II study of 200 patients conducted by Speedel, it was demonstrated that SPP100 achieves dose-dependent blood pressure reduction. The study also showed that 150mg and 300mg SPP100 once daily were comparable to Losartan 100mg, which is double the usual starting dose of this ARB (Stanton, Jensen, Nussberger, O'Brien, Hypertension.2003; 42: 1137-1143).

About Speedel Speedel is a public biopharmaceutical company that seeks to create value for patients, partners and investors by developing innovative therapies for cardiovascular and metabolic diseases. Speedel is a world leader in renin inhibition, a promising new approach with significant potential for treating cardiovascular diseases. Our lead compound SPP100 (Tekturna/Rasilez[1]), the first-in-class direct renin inhibitor, was in-licensed from Novartis in 1999 and licensed-back to Novartis Pharma in 2002 for further development and commercialisation; SPP100 was approved by the FDA in the US in March 2007, and by the EMEA in the EU in August 2007. Our pipeline covers three different modes of action, and in addition to SPP100, includes SPP301 in Phase II, SPP200 in Phase II, SPP635 in Phase Il, SPP1148 and SPP676 in Phase I and several pre-clinical projects. Speedel develops novel product candidates through focused innovation and smart drug development from lead identification to the end of Phase II. We either partner with big pharma for Phase III and commercialisation in primary-care indications, or we may ourselves complete Phase III development in specialist indications. Candidate compounds for development and the company's intellectual property come from our late-stage research unit Speedel Experimenta and from in-licensing. Our team of approximately 80 employees, including over 30 experienced pharmaceutical scientists, is located at our headquarters and laboratories in Basel, Switzerland and at offices in New Jersey, USA and Tokyo, Japan.

In January 2007 the company raised gross proceeds of CHF 55.5 million (approximately EUR 33.5 million or USD 49 million) through a convertible bond issue. In March 2006 the company raised gross proceeds of CHF 83.95 million (approximately EUR 50.7m or USD 74.2m) through the public offering of 500,000 treasury shares. Previously, as a private company, we raised gross proceeds of CHF 256.5 million (approximately EUR 155 million or USD 226.6 million) from private placements of equity securities and two convertible loans including the conversion premiums. We have had total revenues, principally from milestone payments, of CHF 60.8 million (approximately EUR 36.7 million or USD 53.7 million)[6].
