Novartis gains rights to promising hospital antibiotic in clinical development through full acquisition of Protez Pharmaceuticals

Acquisition of Protez Pharmaceuticals provides rights to PZ-601 and further strengthens specialty medicines development portfolio in hospital infections

PZ-601 a novel broad-spectrum antibiotic in Phase II development against potentially fatal drug-resistant infections - including MRSA and ESBL strains

Antibiotic resistance an important public health problem, estimated to account for more than 100,000 deaths annually in the US and Europe together

Novartis to fully acquire privately-held Protez for initial payment of USD 100 million, potential for up to USD 300 million of additional payments contingent upon success of PZ-601

Basel, June 4, 2008 - Novartis has signed a definitive agreement to acquire Protez Pharmaceuticals along with the rights in North America and Europe to PZ-601, a novel hospital antibiotic in clinical development. This transaction is subject to customary conditions for a transaction of this type.

The agreement with Protez, a privately-held US biotechnology company, based in Malvern, Pennsylvania, also provides Novartis with the company's research expertise.

PZ-601 is a new antibiotic in a class of agents known as carbapenems. Medicines in this class are useful in treating life-threatening infections caused by Gram-negative and Gram-positive bacteria. PZ-601, which is administered by injection, has been specifically shown to have a broad spectrum of activity that could offer better coverage over existing injectable antibiotics, especially against multidrug-resistant bacteria including MRSA (methicillin resistant Staphylococcus aureus) strains that are becoming an increasing public health challenge

"Novartis has a long-standing commitment of bringing innovative medicines to severely ill patients and fighting infections that represent significant public health threats," said Joe Jimenez, CEO of Novartis Pharma AG. "The addition of Protez and its pipeline, including PZ-601, to our existing initiatives will further strengthen our position in the specialty field of hospital infections while helping to address the public health challenges of increasing bacterial resistance and high mortality rates."

A 100-patient, Phase II study was started by Protez in May 2008 in the US to evaluate the safety and efficacy of PZ-601 in patients with complicated skin and skin structure infections including cellulites, abscesses, infected wounds and ulcers. Novartis plans to start additional clinical trials for PZ-601, with the aim of first regulatory submissions in 2012.

"This acquisition of Protez by Novartis underscores our company's infectious disease expertise and novel antimicrobial programs," said Christopher Cashman, Protez President and CEO. "We believe the growing presence of Novartis in the specialty field of hospital infections provides Protez the support required to fully execute its vision, advance its product pipeline and positively impact human health. We look forward to contributing to the strength of the global Novartis team."

Antibiotic resistance is one of the world's most pressing public health problems. According to the Centers for Disease Control and Prevention (CDC), two million people in the United States develop hospital-acquired infections each year, and approximately 90,000 die as a result. In Europe, an estimated three million hospital-acquired infections occur each year, resulting in some 50,000 deaths.

The number of bacteria resistant to antibiotics has increased significantly in the last decade, including the potentially fatal type known as methicillin-resistant Staphylococcus aureus (MRSA) - or "staph" - branded as a major public health threat in many countries. Bacte

ria have also been observed with resistance to other antibiotics, including hospital antibiotics such as vancomycin (VRE). In addition, officials have documented multidrug-resistant bacteria known as extended-spectrum beta-lactamase enterobacteriaceae (ESBL) that are considered to be an increasing public health threat.

The addition of PZ-601 further expands the Novartis portfolio of specialty medicines for severe infectious diseases, which already includes approved medicines as well as development compounds for use in treating hospital-based infections and hepatitis.

Novartis markets Cubicin® (daptomycin) in Europe and various other markets for use in treating complicated skin and soft-tissue infections (cSSTI), right-sided infective endocarditis (RIE) due to Staphylococcus aureus (S. aureus) and S. aureus bacteremia (SAB) when associated with RIE or with cSSTI as well as other infections. Cubicin is the first of a new class of antibiotics called cyclic lipopeptides. Development projects involving hospital-based infections include Mycograb(TM) (antifungal), Aurograb(TM) (antibacterial) and Tifacogin (severe community-acquired pneumonia), three biotechnology compounds acquired in 2006 to treat life-threatening conditions.

Terms of the agreement
Under terms of this innovative transaction, Novartis agrees to fully acquire Protez for USD 100 million. Protez's owners are eligible for additional payments of up to USD 300 million, which are contingent upon clinical milestones, regulatory approval for PZ-601 and the achievement of commercialization targets. Dainippon Sumitomo Pharma Co., Ltd. is the IP holder of PZ-601 and retains the rights in other markets. This transaction with Protez is subject to customary conditions for a transaction of this type. Protez will operate as a stand-alone subsidiary of Novartis, continuing its operations in Malvern, Pennsylvania.
