Trial or other data
May 18 · Results of PIII NCT02629861 published in JAMA. RCT (n=875) found both monthly dose and single high dose fremanezumab resulted in larger decreases in migraine days per month vs placebo (difference of 1.5 days and 1.3 days vs placebo respectively, p<0.001 for both) .
Jun 17 · Teva announce positive results from the second PIII HALO study of fremanezumab. Fremanezumab given monthly improved the average number of migraine days, relative to baseline, by 41.6% for the duration of the trial (-3.7 days vs -2.2 days for placebo, p < 0.0001). Number of days with disability were decreased by 64.7% (p =0.0021) and medication consumption was decreased by 39.0% ( p < 0.0001). The quarterly SC dose also yielded significant results for decrease in migraine days (-3.4 days or 37.0%, p < 0.0001) and for all other comparisons. Both dose regimens significantly improved migraine in subjects on stable doses of other prophylactic medications (-4.0 days for monthly dose vs -2.0 days for placebo, p = 0.001; -3.7 days for quarterly dose, p = 0.006) .
Jun 17 · PIII study (NCT02638103) to evaluate long-term safety, tolerability, and efficacy of SC administration of TEV-48125 in adult patients with CM or EM is ongoing in EU and US. Estimated primary completion date is Sept 2018 .
May 17 · Teva announce PIII NCT02621931 met primary endpoint of reduction in number of monthly headache days of at least moderate severity during the 12 week period, for monthly (-4.6) and quarterly (-4.3 days) dosing regimens vs. placebo (-2.5 days, p<0.0001 for both) .
May 17 · In CM (NCT02621931), 1,130 patients were randomized in a 1:1:1 ratio to receive SC fremanezumab 675 mg at initiation followed by monthly 225 mg for 2 months (monthly dose regimen), 675 mg at initiation followed by placebo for 2 months (quarterly dose regimen), or three monthly doses of matching placebo. Primary efficacy endpoint was mean change from baseline (28-day run-in period) in monthly average number of headache days of at least moderate severity during the 12-week period after the first dose of fremanezumab .
May 17 · HALO research programme comprises two 16-week, multicenter, randomized, double-blind, placebo-controlled, parallel-group PIII studies of fremanezumab in episodic (EM) and chronic (CM) migraine. Studies consist of a screening visit, a 28-day run-in period, 84-day treatment period, and end-of-treatment [EOT] visit 28 days after the final dose of study drug. Studies aim to compare safety, tolerability, and efficacy of four dose regimens of SC fremanezumab vs placebo in adults with episodic and chronic migraine .
Sep 15 · Results of PII randomised trial (NCT02025556), investigating safety, tolerability, and efficacy of TEV-48125 for preventive treatment of high-frequency episodic migraine, published in the Lancet Neurology. TEV-48125 reduced the number of migraine days during weeks 9-12 of the study at both doses tested (mean difference in change from baseline vs. placebo of -2.81 days for 225mg and -2.64 days for 675mg) .
Sep 15 · Results of PII randomised trial (NCT02021773), investigating safety, tolerability and efficacy of TEV-48125 for preventive treatment of chronic migraine, published in the Lancet Neurology. TEV-48125 reduced the number of headache-hours during weeks 9-12 of the study at both doses tested (mean difference in change from baseline vs. placebo of -22.74 hours for 675/225mg and -30.41 hours for 900mg) .
