First child vaccinated with Intercell JE Vaccine in India - Pediatric Phase II trial started

» Development process for vaccine launch in endemic countries accelerated – First child vaccinated with IC51
» First administration of Intercell’s JE vaccine to children – Results of Phase II trial are expected in late 2007
» Development plan for endemic regions clearly defined – Market launch expected in 2009

(Vienna, 16. 7. 2007) Intercell AG and its partner Biological E. Ltd. (Hyderabad, India) announced today that the companies have started a pediatric Phase II clinical trial for Intercell’s novel Japanese Encephalitis Vaccine in India.

The randomized and controlled study aims to demonstrate the dose, safety and immunogenicity of Intercell’s JE vaccine compared to a locally available, Korean made mousebrain Japanese Encephalitis vaccine. The study will enroll 60 children at the age of one to three years. It is the first step toward the licensure of a new cell culture derived product in Asia, which is expected in 2009.

“The start of the pediatric clinical trials in India is a major step forward to make our vaccine, which is based on a proven and safe technology, available also for the population, and especially the children, in endemic regions,” states Gerd Zettlmeissl, Chief Executive Officer of Intercell AG.

Vijay Kumar Datla, Chairman and Managing Director of Biological E. Ltd added, “With the spirit and energy of this partnership we aim to make equitable access to this important intervention against JE available in the endemic regions of the world. This trial will be followed by a corresponding Phase III study in both children and adults in India.”

About Intercell’s investigational JE vaccine (IC51)

Intercell´s novel investigational JE vaccine is a purified, inactivated vaccine for active immunization against the Japanese Encephalitis virus. With over 3 billion people living in endemic areas, Japanese Encephalitis, a mosquito‐borne flaviviral infection, is the leading cause of childhood encephalitis and viral encephalitis in Asia.

In successfully concluded pivotal Phase III trials, Intercell’s Japanese Encephalitis vaccine (IC51) demonstrated a favorable safety and immunogenicity profile:
» The immunogenicity of IC51 was at least as good as the U.S. licensed product, JE‐VAX®
» IC51 demonstrated an overall clinical safety profile similar to placebo
» Further, IC51 showed an excellent local tolerability profile in this head‐to‐head study with JE‐VAX®

Intercell’s novel JE vaccine, manufactured in the company’s proprietary manufacturing facility in Scotland, is prepared using tissue culture rather than live organisms and, unlike JE‐VAX®, does not contain any stabilizers such as gelatin or preservatives in its formulation.

On June 13, 2006, Novartis and Intercell announced that the companies had reached an agreement for Novartis to acquire marketing and distribution rights for Intercell’s Japanese Encephalitis Virus Vaccine in the United States, Europe and certain other markets in Asia and Latin America.
