Teva to Present New Analyses of Fremanezumab and Country-Specific Burden of Migraine at 24th World Congress of Neurology

Teva Pharmaceutical Industries Ltd. (NYSE and TASE: TEVA) today announced that 12 new analyses will be presented at the 24^th World Congress of Neurology (WCN), taking place in Dubai, United Arab Emirates on October 27-31, 2019. Among the analyses, Teva will present on fremanezumab's efficacy by country in one of the three oral presentations from the international, multicenter, randomized, placebo-controlled Phase IIIb FOCUS study. The company will also provide data in an oral presentation on the burden of migraine across China, Israel, Russia, South Korea and Turkey, as well as a poster presentation evaluating the burden of migraine across Argentina, Brazil, Chile and Mexico.

"As the largest international study to date evaluating patients with an inadequate response to multiple classes of preventive migraine treatments, we are proud to be presenting the FOCUS results to a global audience," said Joshua M. Cohen, MD, MPH, FAHS, Global Medical Lead for Migraine & Headache, Teva. "This broad range of data highlights our global commitment to helping patients with difficult to treat migraine as well as our leadership in the CNS therapeutic area of research."

The FOCUS study evaluated the efficacy and safety of quarterly and monthly treatment with fremanezumab compared to placebo in adult patients with migraine and documented inadequate response to 2-4 classes of prior preventive treatments. Additional FOCUS data to be presented at WCN include data on reversion from chronic to episodic migraine, data on the odds of achieving meaningful response rates on fremanezumab as compared to placebo, and an analysis demonstrating a significant reduction in the frequency of migraine aura in patients treated with fremanezumab compared to placebo.

About FOCUS

The Phase IIIb FOCUS study is a multicentre, randomised, double-blind, parallel-group, placebo-controlled study that evaluated the efficacy, safety, and tolerability of quarterly and monthly treatment with fremanezumab, compared to placebo. Adult patients with chronic migraine or episodic migraine who have responded inadequately to 2-4 classes of prior preventive treatments were enrolled in the study.

Inadequate response is defined as: lack of efficacy after at least three months of therapy at a stable dose; or the patient cannot tolerate the drug; or the drug is contraindicated; or the drug is not suitable for the patient. The classes of prior preventive medications include: beta-blockers, anticonvulsants, tricyclics, calcium channel blockers, angiotensin II receptor antagonists, onabotulinumtoxinA, and valproic acid.

In the study, chronic migraine and episodic migraine patients were randomised in blinded-fashion 1:1:1 into one of three treatment groups ? a quarterly dosing regimen, a monthly dosing regimen or matching placebo. An open-label extension of three months (weeks 13-24) followed the placebo-controlled portion of the study.

About the HALO Clinical Research Program

The Phase III HALO EM and CM studies were 16-week, multicentre, randomised, double-blind, placebo-controlled, parallel-group studies to compare the safety, tolerability, and efficacy of four dose regimens (two for EM [quarterly and monthly] and two for CM [quarterly and monthly]), of subcutaneous fremanezumab compared to placebo in adults with episodic and chronic migraine. The studies consisted of a screening visit, a 28-day run-in period, and a 12-week (84-day) treatment period, including a final evaluation at week 12 (end-of-treatment [EOT] visit, four weeks [28 days] after the final dose of study drug).

• In the EM study, 875 patients were enrolled (294, 291, 290 patients in the placebo, quarterly, and monthly dose groups, respectively). Patients were randomised in a 1:1:1 ratio to receive subcutaneous injections of fremanezumab at 225 mg for three months (monthly dose regimen), fremanezumab at 675 mg at initiation followed by placebo for two months (quarterly dose regimen), or three monthly doses of matching placebo. The primary efficacy endpoint of the EM study was the mean change from baseline (28-day run-in period) in the monthly average number of migraine days during the 12-week period after the first dose of fremanezumab.

• In the CM study, 1,130 patients were randomised (375, 376, 379 patients in the placebo, quarterly, and monthly groups, respectively). Patients were randomised in a 1:1:1 ratio to receive subcutaneous injections of fremanezumab at 675 mg at initiation followed by monthly 225 mg for two months (monthly dose regimen), fremanezumab at 675 mg at initiation followed by placebo for two months (quarterly dose regimen), or three monthly doses of matching placebo. The primary efficacy endpoint of the CM study was the mean change from baseline (28-day run-in period) in the monthly average number of headache days of at least moderate severity during the 12-week period after the first dose of fremanezumab.
