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 71st 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.”
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).
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
AJOVY® (fremanezumab-vfrm) injection is indicated for the preventive treatment of migraine in adults.
IMPORTANT SAFETY INFORMATION
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 greater than placebo) were injection site reactions.
