The FOCUS study looked at patients who previously experienced inadequate response to two to four migraine preventive medication classes. Treatment with fremanezumab was shown to be effective versus placebo.
Teva Pharmaceutical Industries Ltd. (NYSE and TASE: TEVA) today announced that results from the Phase IIIb FOCUS study, which examined fremanezumab versus placebo in adult migraine patients who previously experienced inadequate responses to two to four classes of preventive treatments, were published online ahead of print in The Lancet. The study found fremanezumab was superior versus placebo across all primary and secondary endpoints. The primary outcome measure of the trial was mean change from baseline in the monthly average number of migraine days during the 12-week treatment period following the first dose. Treatment resulted in statistically significant reductions in monthly average number of migraine days in participants who received either monthly or quarterly dosing with fremanezumab during the study.
“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®■ in Europe.
