Teva to Present New Long-Term Data on Efficacy and Safety of Fremanezumab at 2019 American Academy of Neurology Annual Meeting

Findings describe the efficacy and safety results of clinical trials
of fremanezumab through 12 months of treatment in patients with chronic
and episodic migraine

JERUSALEM–(BUSINESS WIRE)–Teva Pharmaceutical Industries Ltd. (NYSE and TASE: TEVA) today
announced results from new long-term analyses of the efficacy and safety
of fremanezumab, being presented at the 71^st Annual Meeting
of the American Academy of Neurology (AAN) in Philadelphia from May
4-10, 2019.

The findings, presented across 13 abstracts at this year’s meeting,
describe the primary and other key endpoints, as well as pooled and
subgroup data from a 52-week, multicenter, randomized, double-blind,
parallel group long-term extension study that evaluated fremanezumab in
adults with migraine. The results presented include data on the efficacy
of fremanezumab observed through 12 months of treatment in patients with
migraine, including populations with inadequate responses to multiple
classes of preventive medications, quality of life and the safety
profile.

“We are pleased to join the neurology community at this year’s AAN
meeting and share these long-term data results on fremanezumab as a
preventive treatment option for patients living with migraine,” said
Danny McBryan, Senior Vice President, Head of Global Medical Affairs and
Pharmacovigilance at Teva. “These data, studied in a wide range of
migraine patient populations, add to our growing body of evidence about
fremanezumab, and further demonstrate our ongoing commitment to
improving the lives of those who suffer from migraine.”

Analysis design

The long-term extension study of fremanezumab included patients rolled
over from two placebo-controlled studies, as well as 312 newly enrolled
patients. Patients were assigned to either monthly dosing (225 mg
monthly; chronic migraine: starting dose of 675 mg), or quarterly dosing
(675 mg every three months). A total of 1,890 patients were enrolled and
1,494 completed 12 months of treatment. Patients included those with
chronic migraine (CM) and episodic migraine (EM).

Analysis highlights

A selection of key data points of note across the analyses are
summarized below.

Long-term efficacy and safety results:

• In an analysis of the 1,110 patients included in the study with CM,
  those achieving ≥50 percent reduction in monthly average number of
  headache days of at least moderate severity at month 12 was 54 percent
  of patients in the quarterly dosing arm and 59 percent in the monthly
  dosing arm. Those achieving ≥50 percent reduction in monthly average
  number of migraine days at month 12 was 53 percent of patients in the
  quarterly dosing arm and 57 percent of patients in the monthly dosing
  arm. Additionally, patients with CM showed decreased use of any acute
  headache medication and improvements in disability that were observed
  through the one-year treatment period.¹
• An analysis of the 780 patients included in the study with EM
  demonstrated that patients achieving ≥50 percent reduction in migraine
  days at month 12 was 66 percent in the quarterly dosing arm and 68
  percent in the monthly dosing arm. Similar response rates were
  observed for headache days of at least moderate severity. Similar to
  the results observed in CM patients, patients with EM also showed
  decreased use of any acute headache medication and improvements in
  disability that were observed through the one-year treatment period.²
• Additionally, Teva conducted a post-hoc efficacy analysis of 813
  patients with CM at baseline, of which 67 percent (548) reverted to EM
  during the study period. In this subgroup, the average change in the
  monthly number of headache days of at least moderate severity from
  baseline to month 12 was -8.8 for the quarterly dosing arm and -8.5
  for the monthly dosing arm. The mean change in the monthly number of
  migraine days from baseline to month 12 was -10.3 for quarterly and
  -10.4 for monthly. Overall, monthly headache days, migraine days and
  days of acute headache medication use decreased progressively from
  month six and through month 12 in both dosing groups.³
• A safety analysis of all 1,890 patients enrolled in the one-year study
  demonstrated that the most common adverse events (AEs) were
  injection-site reactions, which occurred in 26-33 percent of all
  patients. Four percent of patients discontinued due to adverse events.⁴

Quarterly dosing persistency results:

• Teva also assessed whether patients in the quarterly dosing arm
  experienced any pattern of decreased efficacy during the third month
  after injection (also known as “wearing off” effect). In the analysis
  of 1,103 CM patients and 775 EM patients, outcomes with quarterly
  dosing of fremanezumab were comparable to outcomes with monthly dosing.⁵

Quality of life results:

• The effect of fremanezumab on headache-related disability,
  quality-of-life and patient satisfaction in CM and EM patients was
  assessed using clinically validated questionnaires. Overall, long-term
  treatment with fremanezumab suggested potential improvements in
  disability and quality of life in patients with both CM and EM.⁶

About fremanezumab

AJOVY^® (fremanezumab-vfrm) injection is indicated for the
preventive treatment of migraine in adults.

Contraindications: AJOVY is contraindicated in patients with
serious hypersensitivity to fremanezumab-vfrm or to any of the
excipients.

Hypersensitivity Reactions: Hypersensitivity reactions, including
rash, pruritus, drug hypersensitivity, and urticaria were reported with
AJOVY in clinical trials. Most reactions were mild to moderate, but some
led to discontinuation or required corticosteroid treatment. Most
reactions were reported from within hours to one month after
administration. If a hypersensitivity reaction occurs, consider
discontinuing AJOVY and institute appropriate therapy.

Adverse Reactions: The most common adverse reactions (≥5% and
