Fremanezumabdata publicerad i The Lancet visar på kliniskt betydelsefull reduktion av antalet månatliga migrändagar jämfört med placebo för patienter med svårbehandlad migrän
FOCUS-studien utvärderade Fremanezumabs effekt och säkerhet som preventiv behandling av migrän hos vuxna patienter som tidigare behandlats, utan tillfredsställande resultat, med två till fyra olika klasser migränprofylaktika. Behandling med fremanezumab visade sig vara effektiv jämfört med placebo.
JERUSALEM, August 21, 2019 – Teva Pharmaceutical Industries Ltd. (NYSE och TASE: TEVA) meddelade idag att resultaten från fas IIIb FOCUS-studien publicerats online före publicering av den tryckta versionen av The Lancet. FOCUS-studien undersökte fremanezumab vs placebo hos vuxna migränpatienter som tidigare upplevt otillräcklig effekt av två till fyra klasser av förebyggande behandlingar. Studien fann att fremanezumab var överlägset placebo för alla primära och sekundära effektmått.
Det primära effektmåttet för studien var genomsnittlig förändring från baslinjen i det månatliga antalet migrändagar under en 12-veckors behandlingsperiod efter den första dosen. Behandlingen resulterade i statistiskt signifikanta minskningar av det genomsnittliga antalet månatliga migrändagar hos deltagare som under studien fick antingen kvartals- eller månadsdosering med fremanezumab.
“As a physician, it is extremely rewarding to see that patients with very difficult-to-treat migraine experienced clinically significant improvement with fremanezumab,” said Professor Michel D. Ferrari, MD, PhD, lead author and Chair Leiden Centre for Translational Neuroscience, Leiden University Medical Centre, Leiden, The Netherlands. “More than a third of patients achieved a clinically meaningful 50% reduction in monthly migraine days within just four weeks of initiating treatment.”
Fremanezumab is approved in the U.S. and Europe for the preventive treatment of migraine in adults. The FOCUS study, a randomized, double-blind, parallel-group, placebo controlled study, evaluated the efficacy of two dosing regimens of fremanezumab (675 mg quarterly or 225 mg monthly) in a large population of adult patients (aged 18-70) with episodic or chronic migraine who had documented prior inadequate response* within the past ten years to two-to-four pharmacological classes of migraine preventive medications: beta blockers, anticonvulsants, tricyclic antidepressants (amitriptyline), calcium channel blockers (flunarizine), angiotensin II receptor antagonists (candesartan), onabotulinumtoxinA, or valproic acid.
Between November 2017 and July 2018, 838 patients with episodic (39 percent) or chronic (61 percent) migraine were randomized (1:1:1) by electronic interactive response technology (IRT) at 104 sites in 14 countries to placebo (n=279), quarterly fremanezumab (n=276), or monthly fremanezumab (n=283). Both patients with and without overuse of acute headache medication were included. Reductions from baseline in monthly days with migraine, moderate to severe headache, or use of acute headache medications were about 3.5 days (30 percentage points) greater with fremanezumab than with placebo (p<0.0001). The odds relative to placebo for achieving a ≥50 percent reduction in migraine days as early as four weeks after starting study treatment were approximately six-fold higher with fremanezumab (p<0.0001). Patients treated with fremanezumab had 3.1- to 3.8-day greater reductions in migraine days (from 9.4 to 17.1 days at baseline) across dosing and migraine classification subgroups than patients receiving placebo (p<0.0001), representing a therapeutic gain of 26 to 39 percentage points.
“Migraine can be debilitating for patients – and frustrating for those who have failed multiple preventive treatments,” said Joshua M. Cohen, MD, MPH, FAHS, Global Medical Lead for Migraine & Headache at Teva. “We continue our clinical trial efforts in the area of migraine research and we are very pleased with the FOCUS results. Fremanezumab shows promise for patients with migraine, and being published in the Lancet, a very prestigious medical journal, demonstrates the value of the clinical work being done at Teva to support and elevate the need for migraine education and treatment.”
The most common adverse reactions in the study were injection site reactions. Less than 1 percent of patients in the fremanezumab group experienced an adverse event leading to discontinuation. Patients with major comorbid diseases, including major cardiovascular disease, were excluded from participation in this study.
*Inadequate response was defined as no clinically meaningful improvement after at least three months of therapy at a stable dose, per the treating physician’s judgement; discontinuation due to adverse events that made treatment intolerable; or the treatment was contraindicated or unsuitable for the preventive treatment of migraine for the patient. Documentation of prior failure to migraine preventive medication was generally based on the patient’s medical record, with the medication name, treatment duration, dose level and reason for discontinuation. If obtaining the medical record was not possible, the treating physician could provide an affidavit confirming prior treatment failures according to the protocol definition.
Fremanezumab is available as a 225 mg/1.5mL single dose injection in a prefilled syringe with two dosing options – 225 mg monthly administered as one subcutaneous injection, or 675 mg every three months (quarterly), administered as three subcutaneous injections. Fremanezumab can be administered in office by a healthcare professional or at home by a patient or caregiver. No starting dose is required to begin treatment. Fremanezumab is marketed in the United States as AJOVY® (fremanezumab-vfrm) injection and as AJOVY®q in Europe.
