- Additional subgroup analyses may explain increased ability to detect disease-modifying effects in patients with higher baseline UPDRS scores
- New findings provide further insights into the ADAGIO results which support early treatment initiation with Azilect®

Jerusalem, Israel, April 19, 2010 - Teva Pharmaceutical Industries Ltd. (NASDAQ: TEVA) today announced results from the placebo group analyses of the ADAGIO study (Attenuation of Disease progression with AZILECT® GIven Once-daily) that were presented at the 62nd Annual Meeting of the American Academy of Neurology (AAN). The ADAGIO study stands out from other Parkinson's disease (PD) trials as it is the largest clinical study conducted in patients who were still in the very early stages of their disease course (average time from PD diagnosis of 4.5 months).

The placebo analyses demonstrated that the natural progression of clinical symptoms in PD may be slower in the earlier stages of disease development than was expected from previous findings. These results may have implications for the overall interpretation of the ADAGIO results. Specifically, the clinical significance of the 1.7 UPDRS (Unified Parkinson's Disease Rating Scale) units seen between the AZILECT® (rasagiline tablets) 1 mg/day early and delayed-start groups during the nine month time period represents, on average, a 40 percent reduction from baseline in the early group when compared to the delayed group.

The results of the subgroup analysis showed faster progression in placebo patients with the highest baseline UPDRS scores (upper quartile), which may provide an explanation for the reported ability to detect a larger magnitude of disease-modifying effect with AZILECT® in ADAGIO patients in this subgroup.

"One interpretation about what was found in the subgroup analyses of placebo patients with the highest UPDRS scores is that the faster progression of these patients may explain the previously reported ability to detect a larger magnitude of disease modifying effect in this population, as well as a significant effect for the 2 mg dose," said Olivier Rascol, MD, University UPS, Toulouse, France, the co-principal investigator of the ADAGIO study.

About the Study

The Natural Progression of Clinical Symptoms in Parkinson's Disease may Not Be Faster in the Earlier Stages: Results From the ADAGIO Delayed-Start Study

The ADAGIO study was an 18-month, placebo-controlled, double-blind, multicenter trial using a delayed-start design, involving patients with early, previously untreated Parkinson's disease (PD) (n=1176). Subsequent analyses were performed on placebo subjects (n=588), including a subgroup analysis of those with high (>25.5) and low (=14) baseline total UPDRS scores. Overall, the rate of progression for subjects on placebo was slower than anticipated (~6 UPDRS units/year), despite the fact that subjects were recruited at an earlier stage of disease progression than other trials as well as the belief that dopaminergic cell loss is thought to progress faster in the earlier stages of the disease.

Patients on placebo with more advanced PD (higher UPDRS baseline scores; n=145) showed faster disease progression (change from baseline extrapolated to 9 units/year as measured by Total-UPDRS). In contrast, patients with less advanced disease (lower UPDRS baseline scores; n=160) deteriorated at a slower pace (by 4 units/year as measured by Total-UPDRS).
