Objective: To evaluate the impact of fremanezumab on the severity and duration of remaining migraine attacks in patients with chronic migraine (CM) or episodic migraine (EM). Background: Fremanezumab is a fully humanized monoclonal antibody (IgGΔa) that selectively targets calcitonin gene‐related peptide and is efficacious in reducing migraine frequency. Methods: This exploratory post hoc analysis included data from three randomized, double‐blind, 12‐week, phase 3 studies (HALO CM, HALO EM, and FOCUS). In all three studies, patients with CM or EM were randomized 1:1:1 to receive subcutaneous quarterly fremanezumab (month 1/2/3: 675 mg/placebo/placebo), monthly fremanezumab (month 1/2/3: 675 mg [CM], 225 mg [EM]/225 mg/225 mg), or matched monthly placebo. Changes from baseline were evaluated in the proportion of headache days of at least moderate severity, peak severity of headache days, mean monthly headache hours (of any severity and at least moderate severity), and mean headache hours per headache day of any severity. Results: A total of 2843 patients were randomized with 2823 patients included in the efficacy analyses across all studies (HALO CM, N = 1121; HALO EM, N = 865; FOCUS, N = 837). At study baseline, mean (standard deviation [SD]) monthly number of headache days rated moderate or severe in the quarterly fremanezumab, monthly fremanezumab, and placebo groups, respectively, were 13.2 (5.5), 12.8 (5.8), and 13.3 (5.8) in HALO CM; 7.2 (3.1), 6.8 (2.9), and 6.9 (3.1) in HALO EM; and 12.4 (5.8), 12.7 (5.8), and 12.8 (5.9) in FOCUS. Patients experienced significant least‐squares mean (LSM; 95% confidence interval) percent reductions from baseline in monthly number of headache days rated moderate or severe during the 12 weeks: HALO CM, quarterly fremanezumab, 34.5% (−39.8, −29.2) and monthly fremanezumab, 36.2% (−41.4, −31.0) vs. placebo, 19.6% (−20.0, −14.3); HALO EM, quarterly fremanezumab, 40.7% (−47.8, −33.5) and monthly fremanezumab, 43.4% (−50.4, −36.3) vs. placebo, 17.9% (−24.9, −11.0); and FOCUS, quarterly fremanezumab, 36.5% (−41.9, −31.1) and monthly fremanezumab, 38.6% (−44.0, −33.3) vs. placebo, 3.5% (−8.9, 1.8); all p < 0.0001. At study baseline, mean (SD) number of monthly headache hours rated moderate or severe in the quarterly fremanezumab, monthly fremanezumab, and placebo groups, respectively, were 66.4 (58.8), 68.0 (53.9), and 68.5 (57.0) in HALO CM; 33.3 (25.4), 31.7 (23.7), and 31.6 (23.2) in HALO EM; and 59.2 (54.7), 64.3 (65.2), and 65.9 (70.2) in FOCUS. Significant reductions were observed in LSM (standard error) number of monthly headache hours of at least moderate severity: HALO CM, quarterly fremanezumab, 24.4 (2.5) and monthly fremanezumab, 26.4 (2.3) vs. placebo, 14.1 (2.5); HALO EM, quarterly fremanezumab, 14.5 (1.4) and monthly fremanezumab, 15.5 (1.3) vs. placebo, 8.1 (1.3); and FOCUS, quarterly fremanezumab, 16.8 (3.0) and monthly fremanezumab, 18.3 (3.0) vs. placebo, 2.3 (3.0); all p < 0.001. Conclusion: These analyses demonstrated that quarterly or monthly treatment with fremanezumab significantly reduced headache severity and duration in patients with CM or EM, including in patients with documented inadequate response to two to four prior migraine preventive medication classes.

Objective: To evaluate the efficacy of fremanezumab in patients with chronic migraine (CM) and moderate to severe depression. Background: Fremanezumab, a fully humanized monoclonal antibody that selectively targets calcitonin gene–related peptide, has been approved for the preventive treatment of migraine in adults. CM and depression are highly comorbid. Methods: The 12‐week, Phase 3 HALO trial randomized patients with CM to fremanezumab quarterly (675 mg/placebo/placebo), fremanezumab monthly (675/225/225 mg), or placebo. Post hoc analyses evaluated the effects of fremanezumab in patients with moderate to severe depression (baseline 9‐item Patient Health Questionnaire sum score ≥10) on monthly number of headache days of at least moderate severity; monthly migraine days; Patient Global Impression of Change (PGIC); 6‐item Headache Impact Test (HIT‐6) scores; and depression. Results: For the 219/1121 (19.5%) patients with moderate to severe depression at baseline, fremanezumab was associated with a significant reduction in monthly number of headache days of at least moderate severity for active treatment versus placebo (least‐squares mean change ± standard error for quarterly dosing: −5.3 ± 0.77; for monthly dosing: −5.5 ± 0.72; and for placebo: −2.2 ± 0.81; both p < 0.001). More patients achieved a ≥50% reduction in headache days of at least moderate severity with fremanezumab (quarterly: 31/78 [39.7%]; monthly: 39/96 [40.6%]) than placebo (9/67 [13.4%]; both p < 0.001). Compared with placebo, fremanezumab improved PGIC and HIT‐6 scores. Conclusions: Fremanezumab demonstrated efficacy in the preventive treatment of CM and reduced headache impact in patients with comorbid depression. [ABSTRACT FROM AUTHOR]

Background: Migraine preventive medications are used to reduce headache frequency, severity, and duration. In patients with chronic migraine (CM), reversion to episodic migraine (EM) is an important treatment goal. Objective: To evaluate the effect of fremanezumab on the rate of reversion from CM to EM. Methods: This phase 3, randomized, double‐blind, placebo‐controlled, parallel‐group trial included a 28‐day pretreatment period and a 3‐month treatment period. Patients with CM received subcutaneous fremanezumab quarterly (675 mg at baseline) or monthly (675 mg at baseline; 225 mg at Weeks 4 and 8), or placebo. Post hoc analyses evaluated the proportion of patients who reverted from CM to EM, defined as either a reduction to an average of <15 headache days per month during the 3‐month treatment period or a reduction to <15 headache days per month in all 3 months of the treatment period. Results: This analysis included data from 1088 CM patients (quarterly, n = 366; monthly, n = 365; placebo, n = 357). More fremanezumab‐treated patients with CM reverted to EM using either the monthly average number of headache days criteria for reversion (quarterly: 50.5% [185/366], P =.108; monthly: 53.7% [196/365], P =.012; vs placebo: 44.5% [159/357]) or the monthly headache day count at Months 1, 2, and 3 criteria for reversion (quarterly: 31.2% [114/366], P =.008; monthly: 33.7% [123/365], P =.001; vs placebo: 22.4% [80/357]). Patients with CM who reported previous topiramate or onabotulinumtoxinA use, concomitant preventive medication use, or medication overuse were less likely to revert to EM. Conclusions: Fremanezumab may offer the benefit of reversion from CM to EM, based on a reduction in the number of headache days over 3 months of treatment. [ABSTRACT FROM AUTHOR]

Objective: To evaluate whether quarterly or monthly administration of fremanezumab for migraine prevention exhibits a pattern of decreased efficacy toward the end of the dosing interval (wearing‐off effect). Background: The main goals of migraine preventive treatment are to reduce the frequency, severity, and duration of migraine attacks, and migraine‐associated disability. Wearing‐off refers to the phenomenon whereby clinical symptoms return or worsen before the next dose of a drug is due and has been reported previously with migraine preventive medications. Design and Methods: This was a long‐term, 12‐month, multicenter, randomized, double‐blind, parallel‐group phase 3 study (NCT02638103) that included chronic (CM) and episodic migraine (EM) patients who rolled over from the 12‐week phase 3 HALO CM (NCT02621931) and EM trials (NCT02629861), as well as an additional subset of 312 new patients. Patients with CM or EM received fremanezumab either monthly or quarterly. In this post hoc analysis, for selected months, the difference in the average number of migraine days between weeks 1‐2 and weeks 3‐4, between weeks 1‐3 and week 4, and between weeks 1‐2 and weeks 11‐12 were calculated. Results: A total of 1890 patients (CM, 1110; EM, 780) were enrolled. At months 3, 6, 9, and 15, there were no substantial differences in mean weekly migraine days between weeks 1‐2 and weeks 3‐4 or between weeks 1‐3 and week 4 with quarterly or monthly fremanezumab in the CM or EM subgroups. There were no substantial increases in mean weekly migraine days between weeks 1‐2 and weeks 11‐12 during the first quarter of treatment (months 1‐3) or the second quarter of treatment (months 4‐6) with quarterly or monthly fremanezumab in the CM or EM subgroups. Across both dosing subgroups in CM and EM patients, the mean weekly number of migraine days decreased substantially (30%‐42%) during the first 2 weeks; decreases in weekly migraine days remained steady during the last 2 weeks of the first quarter, with a similar maintenance of response during the second quarter. Conclusions: This analysis of data from a long‐term, phase 3 study showed that patients receiving quarterly fremanezumab or monthly fremanezumab did not experience a wearing‐off effect toward the end of the dosing interval.

Background Fremanezumab (formerly TEV-48125) is a monoclonal antibody directed against calcitonin-gene-related peptide (CGRP), a validated target for migraine preventive therapy. In two previous phase 2 studies, fremanezumab administered once every 28 days for 12 weeks was found to be effective and safe as a preventive treatment for patients suffering from episodic migraine (EM) and chronic migraine (CM). Objective To evaluate the efficacy and safety of fremanezumab as an add-on preventive therapy in individuals with EM and CM who are on stable doses of preventive migraine medications. Methods Two randomized placebo-controlled studies tested once-monthly subcutaneous injections of various dosing regimens of fremanezumab versus placebo in EM and CM. Headache information was captured daily using an electronic headache diary. For these post hoc analyses, data were pooled from patients who were on stable preventive medications and taking fremanezumab doses of 225 mg or 675/225 mg, or placebo. Results The sample consisted of 133 patients, (67 fremanezumab and 66 placebo). Total reduction in migraine days for the duration of the study was 12.4 for fremanezumab and 7.4 for placebo ( P = .0321). There were also decreases in moderate/severe headache days (12.5 vs 7.1, P = .0058), and days using acute medication for headaches relative to placebo (11.6 vs 7.5, P = .0414). Treatment emergent adverse events were generally mild and transient, and no serious adverse events were considered to be treatment-related by the site investigators. Conclusions The findings from these post hoc analyses suggest that fremanezumab is a safe and effective add-on treatment for migraine patients being concomitantly treated with other migraine preventive medications. Trials are registered at NCT02025556 and NCT02021773. [ABSTRACT FROM AUTHOR]
