Treatment with Copaxone Plus Minocycline Showed Substantial Reduction of Disease Activity in Patients with Active Relapsing-Remitting Multiple Sclerosis

Combination Treatment With Antibiotic Further Reduced Brain Lesions and Was Well Tolerated

KANSAS CITY, Mo, May 4, 2007 - New data from a randomized, double-blind study showed that a combination of Copaxone (glatiramer acetate injection) along with the oral antibiotic minocycline reduced T1 Gadolinium (Gd)-enhancing lesions of the brain by 63 percent (p=0.08) in patients with active relapsing-remitting multiple sclerosis (RRMS), as measured by magnetic resonance imaging (MRI), compared to those receiving Copaxone alone. Additionally, the nine-month study demonstrated that treatment with Copaxone in combination with minocycline reduced the number of new T2 lesions in patients by 65 percent (p=0.06). These results trended toward but did not reach statistical significance.

These data were presented at the 59th Annual Meeting of the American Academy of Neurology (AAN) in Boston, MA, April 28 - May 5, 2007.

"The results of this study indicated that further exploration of this combination is warranted, as the established effect of COPAXONE(r) on disease activity may be boosted when used in combination with minocycline for the treatment of active relapsing-remitting patients," said Luanne Metz, M.D., professor at the Department of Clinical Neuroscience of the University of Calgary, and principal investigator. "In these patients, the combination was safe and well tolerated," she added.

Minocycline is a broad-spectrum antibiotic, which is used to treat pneumonia, acne, and infections of the skin, genital and urinary systems, and the central nervous system. In a small proof-of-concept trial of 10 RRMS patients, minocycline demonstrated an 84 percent relative reduction in mean total Gd-enhancing lesions and was well tolerated, and data published in the Journal of Neuroimmunology indicated that the combination of minocycline and COPAXONE(r) decreased neuron-inflammation, axonal loss and demyelination in an animal model of MS.

"COPAXONE(r) is one of the most frequently used RRMS therapies due to its proven efficacy and safety and unique presumed mechanism of action," said Metz. "In previous studies, COPAXONE(r) has shown efficacy and safety both in combination with intravenous steroids and after induction

with the immunosuppressant mitoxantrone; its compatibility with other compounds may make it unique among the disease modifying class of drugs and a treatment of interest for the future study of combination therapies for MS," Metz added.

About the Study

This double-blind, randomized study evaluated the safety, tolerability and efficacy of the combination of COPAXONE(r) plus oral minocycline in the treatment of RRMS patients with active disease.

Patients in this study (n=44) with one or more T1-enhancing lesions on their screening MRI were randomized to receive either COPAXONE(r) 20 mg daily plus minocycline 100 mg twice daily or COPAXONE(r) plus placebo for nine months. Patients were assessed clinically and by MRI scans at screening and months 1, 3, 8 and 9. The primary outcome was the total number of T1-enhancing lesions at months 8 and 9.

Forty patients completed the study. Groups were balanced at baseline except for greater T1-enhancing lesion number in the COPAXONE(r) plus minocycline group (median 3 versus 2; mean 7.62 versus 2.43 (p=0.07)). Despite this imbalance, treatment trended toward significance in the COPAXONE(r) plus minocycline group. At months 8 and 9, the number of T1-enhancing lesions was reduced by 63 percent (mean 1.47 versus 2.95; p=0.08) and the number of new T2 lesions was reduced by 65 percent (mean 1.84 versus 5.14; p=0.06), compared to COPAXONE(r) alone. Relapse risk rate was also non-significantly reduced in the COPAXONE(r) plus minocycline group (0.19 versus 0.41; p=NS).

About COPAXONE(r)

Current data suggest COPAXONE(r) (glatiramer acetate injection) is a selective MHC class II modulator. COPAXONE(r) is indicated for the reduction of the frequency of relapses in RRMS. The most common side effects of COPAXONE(r) are redness, pain, swelling, itching, a lump or an indentation at the site of injection, weakness, infection, pain, nausea, joint pain, anxiety, and muscle stiffness.

COPAXONE(r) is now approved in 47 countries worldwide, including the United States, Canada, Mexico, Australia, Israel, and all European countries. In Europe, COPAXONE(r) is marketed by Teva Pharmaceutical Industries Ltd. and sanofi-aventis. In North America, COPAXONE(r) is marketed by Teva Neuroscience, Inc., which is a subsidiary of Teva Pharmaceutical Industries Ltd (NASDAQ:TEVA).

COPAXONE(r) TREATMENT OVER TWO YEARS AFTER SHORT TERM INDUCTION WITH MITOXANTRONE PROVIDED SUSTAINED BENEFITS TO ACTIVE RELAPSING-REMITTING MULTIPLE SCLEROSIS PATIENTS

Increased efficacy on MRI and clinical outcomes achieved at 15 months was sustained for 24 months in follow-up study

Kansas City, Mo, May 4, 2007 - New data have demonstrated that relapsing-remitting multiple sclerosis (RRMS) patients treated with COPAXONE(r) (glatiramer acetate injection) following brief immunosuppression with mitoxantrone experienced a 90 percent reduction in magnetic resonance imaging (MRI)-monitored disease activity compared to their baseline. These benefits were achieved early on and were sustained throughout the 24-month study period. These long-term data were consistent with the 15-month initial results of this study, previously presented at an international meeting on multiple sclerosis (MS), which demonstrated that the induction treatment strategy was more effective than COPAXONE(r) alone on reducing relapses and MRI measures of disease activity (p=0.0147). Treatment with COPAXONE(r) after induction with mitoxantrone remained safe and effective throughout the treatment period.

These new findings were presented at the 59th Annual Meeting of the American Academy of Neurology (AAN) along with new confirming MRI findings from the 15-month study, which showed that the decreases in clinical and MRI markers of disease activity, were accompanied by favorable effects on disease burden and irreversible brain tissue damage as shown by significant decreases in the accumulation of lesion load, and significant reduction in the proportion of lesions evolving into chronic black holes.

"This combination therapy is emerging as a promising treatment option for patients who have active RRMS, or who are not responding optimally to traditional first-line therapies," said Tim Vollmer, M.D., Director, Neuroimmunology Program, Barrow Neurological Institute at St. Joseph's Hospital and Medical Center and the primary investigator in this study. "This study builds on earlier studies that demonstrate the effect of COPAXONE(r) on disease activity and inflammation in the central nervous system of RRMS patients," he added.

Data analysis surrounding the mode of action of this novel treatment strategy was also presented at the AAN, in which researchers attributed the benefit of the combination of therapies to the combined anti-inflammatory effect of COPAXONE(r) and mitoxantrone.

"These data shed new light on the concept of treating MS by first suppressing the auto-aggressive immune system with an immunosuppressant, and then favorably modifying its activity with an immunomodulator such as COPAXONE(r)," said Amit Bar-Or, M.D., FRCPC, assistant professor, Director of the Experimental Therapeutics at the Montreal Neurological Institute (MNI) and primary investigator of the immunological study.

About the Analyses

The analysis, Reductions in MRI Disease Activity and Relapse Rates Observed after Induction of Short-term Immunosuppression with Mitoxantrone Followed by Long-term Glatiramer Acetate (GA) Are Maintained at 24 Months in Patients with Relapsing Remitting Multiple Sclerosis (RRMS), determined that the increased efficacy and the safety observed at 15 months with COPAXONE(r) after brief mitoxantrone therapy was maintained with continued COPAXONE(r) at 24 months. The original study included RRMS patients (n=40), ages 18-55, who had at least one Gd-enhancing lesion at the time of the screening MRI and an Expanded Disability Status Scale (EDSS) score of ˜ 6.5. Brain MRIs were performed at screening and months six, nine, 12 and 15.

Patients were randomized to receive 3 monthly intravenous (IV) infusions of mitoxantrone (36 mg/m2 total) followed by a 2-week washout, then COPAXONE(r) 20 mg/d for 12.5 months (n=21) or COPAXONE(r) 20 mg/d alone (n=19) for 15 months.

In the 24-month follow-up of continued COPAXONE(r) therapy, primary outcomes were safety and tolerability. Secondary outcomes included changes from baseline to 24 months in Gd-enhancing lesions, relapses and EDSS.

Thirty patients entered the extension study. Analyses at 15 months indicated a 70 percent reduction in Gd-enhancing lesions in the mitoxantrone-COPAXONE(r) group vs COPAXONE(r) group (risk ratio=0.30, 95 percent CI [0.11-0.86], p=0.0147). These effects appeared to be sustained.

The analysis, Reductions in Gd Enhancing Lesions Observed with Glatiramer Acetate Following a Brief and Low Dose Course of Mitoxantrone in Patients with Relapsing Remitting Multiple Sclerosis (RRMS) Are Paralleled by Favorable Effects on MRI Markers of Disease Burden and Black Hole Evolution, evaluated whether effects on MRI markers of disease burden and tissue damage corroborate the beneficial effects on disease activity observed 15 months after initiating COPAXONE(r) therapy with a brief, low dose induction with mitoxantrone.

This analysis compared patients who were randomized to receive either three months of induction treatment with mitoxantrone followed by COPAXONE(r) for 12 months (n=21) or COPAXONE(r) alone (n=19) for 15 months.

The further MRI analyses showed that the reductions in Gd-enhancing lesions and relapse activity seen at 15 months were accompanied by significant differences favoring the mitoxantrone-COPAXONE(r) group in the change from baseline in the volume of T2-weighted lesions (p=0.0139), the volume of T1-weighted lesions (p=0.0303) and the proportion of Gd-enhancing lesions that evolved into chronic black holes at month 15 (p=0.0023).

The analysis, "Tracking In Vivo Immune Modulation in MS Patients Treated with Glatiramer Acetate (GA) Alone, or with GA Preceded by Mitoxantrone, Provides Novel Insights into the Mode of Action of Therapeutic Strategies That Combine Immune Suppression and Immune Deviation" examined the mechanism of action of the combination of COPAXONE(r) and mitoxantrone versus treatment with COPAXONE(r) alone.

The abstract is accessible online at: http://www.abstracts2view.com/aan2007boston/view.php?nu=AAN07L_P01.046&terms .

Findings of this immunological analysis comparing patients who received either 3 months of induction treatment with mitoxantrone followed by COPAXONE(r) for 12 months or COPAXONE(r) alone for 15 months, was designed to determine whether the improved clinical and MRI outcomes reflect an enhanced capacity for COPAXONE(r)-mediated Th2 shift following immune suppression. Researchers serially measured patients' (n=21) serum for COPAXONE(r)-reactive antibodies (Total IgG: IgG1, IgG2, IgG3, IgG4) by ELISA (enzyme-linked immunosorbant assay). The relationship between IgG1 and IgG4 COPAXONE(r)-reactive antibodies has been determined to be a useful marker of COPAXONE(r)-mediated Th2 shift.

Researchers concluded that induction with mitoxantrone appears to partially reduce and/or delay the IgG1 to IgG4 switch characteristic of the Th2 shift. This information, coupled with MRI measures of disease activity suggest the enhanced efficacy of COPAXONE(r)-mitoxantrone over COPAXONE(r) alone is not due to an enhanced Th2-shift but rather reflects combined anti-inflammatory effects of COPAXONE(r) and mitoxantrone.
