Teva and Active Biotech Announce the Submission of an IND to the FDA for Laquinimod, an Oral Product for the Treatment of Relapsing MS.

JERUSALEM & LUND, Sweden -- Teva Pharmaceutical Industries Ltd. (NASDAQ: TEVA) and Active Biotech AB (Stockholm: ACTI.ST) announced today the submission of an investigational new drug application (IND) to the U.S. Food and Drug Administration (FDA) to initiate a clinical trial in the U.S. with laquinimod to assess drug-drug interaction. Based on the results of this study and of the ongoing phase IIb study in Europe (see below), the phase III clinical program to confirm the efficacy and safety of laquinimod in relapsing forms of MS, is planned to start in 2006.

Laquinimod is a novel orally administered immunomodulatory substance, developed by Active Biotech and recently licensed to Teva.

"I am pleased to report on this significant milestone," said Israel Makov, President and CEO of Teva. "This IND filing is an important step towards the initiation of pivotal studies with laquinimod which, along with Teva's development of an oral form of Copaxone(R), enhance the likelihood that Teva will be the first to market an oral treatment. This further demonstrates our commitment to developing new and improved therapies for multiple sclerosis patients in order to help treat their disease and improve their quality of life".

"We are very pleased to see how Teva's development program is diligently progressing towards starting phase III studies in the U.S. and Europe," said Sven Andreasson, President & CEO of Active Biotech. "Laquinimod has a profile that meets the need for a safe and efficacious oral MS drug suitable for long term treatment."

Laquinimod has the potential to be the first orally-administered disease modifying treatment for multiple sclerosis, both as a single agent therapy and in combination with Copaxone(R), Teva's well-established and leading product on the market today.

A double-blind, placebo-controlled multi center phase IIb clinical study is currently on-going in several European countries, in which the effects of laquinimod, administered orally, once-daily, at dose levels of 0.3 and 0.6 mg/day, are compared to those of placebo over 9 months of treatment.

About laquinimod

Laquinimod is a novel immunomodulatory substance developed as an orally bio-available disease modifying treatment of MS. Laquinimod is the lead candidate drug identified from Active Biotech's SAIK research program, in which the safety/activity ratio has been optimized.

In a completed randomized, double-blind, placebo-controlled, multi-center phase II trial, 209 patients received either laquinimod, at dose levels of 0.1 or 0.3mg/day, or placebo, orally, once daily for 24 weeks. Laquinimod, at the dose of 0.3mg/day, reduced disease activity (as measured by MRI) by 44%. In a sub-group of patients with active MRI brain lesions prior to treatment initiation, the same dose of laquinimod reduced disease activity by 52%. In this study, laquinimod demonstrated a very favorable safety profile, suitable for long-term treatment (Neurology 2005; vol 64, No. 6 p 987).

About Multiple Sclerosis (MS)

Multiple sclerosis (MS) is a chronic, progressive disease of the central nervous system. It is the most common neurological disease causing disability in young adults. It has been described as an autoimmune disease because it is one of many diseases in which the immune system attacks healthy areas of the body as if they were foreign. In MS, these attacks are aimed at the central nervous system. The central nervous system is made up of nerves covered by a substance called myelin, which is similar to insulation protecting electrical wires because it surrounds and protects nerve fibers. When myelin or the nerve fiber is destroyed or damaged, the nerves cannot send electrical impulses to and from the brain, causing the onset of MS symptoms.
