Data presented at the 26th Congress of the European Committee for Treatment and
Research in Multiple Sclerosis (ECTRIMS)

Jerusalem, Israel and Lund, Sweden, October 15, 2010 - Teva Pharmaceutical
Industries Ltd. (NASDAQ: TEVA) and Active Biotech (NASDAQ OMX NORDIC: ACTI)
announced today that data providing further evidence of the neuroprotective
properties of laquinimod in animal studies were presented at the 26th Congress
of the European Committee for Treatment and Research in Multiple Sclerosis
(ECTRIMS) in Gothenburg, Sweden. Laquinimod is an investigational, once-daily
oral immunomodulator for the treatment of relapsing remitting multiple sclerosis
(RRMS).

These results, generated from several pre-clinical studies evaluating the
mechanism of action (MOA) of oral laquinimod, demonstrated that:

* Laquinimod reverts the disruption of neurogenic processes that can occur
with chronic
            inflammation in the central nervous system (CNS), and is
associated with a significant reduction
            in the percentage of demyelination and axonal damage.

* Laquinimod differentially influenced the activity of select immune cells,
reducing their pro-
            inflammatory characteristics while increasing the production of
neurotrophic factors known to be
            involved in neuroprotection and repair mechanisms.

* Laquinimod treatment is associated with an increase in brain-derived
neurotrophic factor (BDNF),
            a pivotal factor in the development and maintenance of the CNS.

"These results add to the accumulating body of data establishing the novel MOA
of laquinimod. These MOA studies suggest that laquinimod has the potential to
prevent demyelination, which is associated with multiple sclerosis, and
therefore may provide neuroprotection in the treatment of RRMS," said Prof. Ralf
Gold, Department of Neurology, St. Josef-Spital, Ruhr University Bochum,
Germany. "Research is ongoing to further evaluate laquinimod, and we look
forward to additional data, including the forthcoming results from the Phase III
clinical development program."

Laquinimod received Fast Track designation from the U.S. Food and Drug
Administration (FDA) in February 2009. Two global Phase III clinical studies,
ALLEGRO and BRAVO, have completed enrollment and are currently ongoing, with
results anticipated in 2011.

ABOUT THE STUDIES

* [P885] Laquinimod prevents the inflammation-induced derangement of
neurogenic niches
            in experimental autoimmune encephalomyelitis mice.

Poster Session: Neuroprotection 2, October 15, 3:30pm-5:00pm CET (F. Ruffini, A.
Bergamaschi, C. Marinaro, R. De Ceglia, L. Muzio, R. Furlan, L. Hayardeny, G.
Comi, G. Martino)

* To determine if laquinimod is capable of reverting non-cell autonomous
dysfunction of endogenous neural stem cells following chronic
inflammation within the central nervous system (CNS), C57Bl/6 mice were
immunized with myelin oligodendrocytes glycoprotein (MOG) peptide 35-55
and treated subcutaneously (s.c.) with increasing doses of laquinimod
(1, 5, 10 or 25 mg/kg laquinimod). At the end of the study (day 25
p.i.), CNS of EAE mice was collected for pathological and molecular
studies. Pathological and molecular study results in mice with EAE
suggest that treatment with 25 mg/kg of laquinimod administered after
EAE onset resulted in a significant reduction in the percentage of
demyelination and axonal damage as well in the number of inflammatory
responses.   An in vivo increase in cell proliferation was also
observed.
[P881] Laquinimod ameliorates experimental autoimmune encephalomyelitis via
BDNF-
            dependent mechanisms.

Poster Session: Neuroprotection 2, October 15, 3:30pm-5:00pm CET (J. Thöne, D.
Lee, S. Seubert, L. Hayardeny, R. Linker, R. Gold)

* To further elucidate the mechanism of action of laquinimod and to
examine its potential neuroprotective capacity via modulation of BDNF
secretion, laquinimod was tested in myelin oligodendrocyte glycoprotein
(MOG) induced EAE experiments using mice at 6-8 weeks of age on C57Bl/6J
background, and with a conditional deficiency for BDNF in T cells and
monocytes (LLF mice). Histological analyses reveal that mice with BDNF
deficiency, treated with laquinimod, had more severe experimental
autoimmune encephalomyelitis (EAE), or animal model of MS progression,
than mice not BDNF deficient, and actually experience an increase in
BDNF levels. This suggests that the mechanism of action of laquinimod is
BDNF dependent and may contribute to neuroprotection.
[P882] Differential activity of laquinimod on production of inflammatory
molecules and
            neurotrophic factors by human microglia and macrophages.

Poster Session: Neuroprotection 2, October 15th, 3:30pm-5:00pm CET (C. Silva, J.
Wang, M. Mishra, V.W. Yong)

* To determine whether laquinimod modulates the production of inflammatory
molecules and growth factors by microglia and macrophages, the cells
were isolated from the peripheral blood of healthy adult human
volunteers and cultured from the brains of human fetal samples or from
adult human surgical brain resections.  Cytokines and matrix
metalloproteinase-9 (MMP-9) were measured by ELISA of cell-conditioned
media and growth factor transcripts were determined using PCR of
cellular extracts. Treatment with laquinimod reduces the expression of
inflammatory responses by autoimmune microglia and in healthy human
cells and increases production of the neuroprotective BDNF by threefold.

[P251] Laquinimod rescue therapy in mice with experimental autoimmune
            encephalomyelitis.

Poster Session: Experimental Models 1, October 14th, 2010, 3:30pm-5:00pm CET (C.
Wegner, R. Pförtner, W. Brück)

* To test whether laquinimod could improve EAE symptoms as a late-stage
rescue therapy. The next goal was to assess if this late-stage treatment
alters the extent of demyelination and inflammation in MOG induced EAE.
Laquinimod rescue therapy given from days 30 to 60 improved clinical
disease scores in the majority of animals in comparison to the control
group. Findings indicate that late stage therapy with laquinimod is
effective in ameliorating the disease severity. Results indicate that
laquinimod may have a role in future treatment of MS.

ABOUT MULTIPLE SCLEROSIS

Multiple sclerosis (MS) is the leading cause of neurological disability in young
adults. It is estimated that more than 400,000 people in the United States are
affected by the disease and that two million people may be affected worldwide.
MS is a progressive, demyelinating disease of the central nervous system
affecting the brain, spinal cord and optic nerves. Demyelination is the
destructive breakdown of the fatty tissue that protects nerve endings.

ABOUT LAQUINIMOD

Laquinimod is a novel once-daily, orally administered immunomodulatory drug
being developed as a disease-modifying treatment for RRMS. Active Biotech
developed laquinimod and licensed it to Teva Pharmaceutical Industries, Ltd. in
June 2004. Results from a Phase IIb study in 306 patients were published in June
2008 in The Lancet, and reported that an oral 0.6 mg dose of laquinimod,
administered daily, significantly reduced MRI disease activity by a mean of 51
percent (p<0.0001) and median of 60 percent (p=0.01) versus placebo in RRMS
patients. Some transient and dose-dependent increases in liver enzymes were
reported, without clinically-evident liver damage.

Two pivotal, global Phase III studies of laquinimod for the treatment of RRMS,
ALLEGRO and BRAVO, are nearing completion. ALLEGRO, a 24-month multinational,
double-blind, placebo-controlled study, designed to evaluate the efficacy,
safety and tolerability of laquinimod versus placebo in the treatment of RRMS,
enrolled 1,106 patients and data from the study are expected in Q1 2011.  BRAVO,
 a 24-month multinational, multi-center, randomized, parallel-group study
designed to evaluate laquinimod compared to placebo, as well as to provide risk-
benefit data for laquinimod compared to a currently available injectable
treatment, Avonex®, has enrolled 1,332 patients and will be complete in Q3 2011.

In addition to the ongoing RRMS clinical studies, laquinimod is currently in
Phase II development for Crohn's disease and Lupus, and is being studied in
other autoimmune diseases.
