Allergan Announces Positive Phase 3 ACHIEVE II Trial Results for Ubrogepant Published in The Journal of the American Medical Association
"Migraine is the second leading cause of disability, and we need new acute treatments that are efficacious, safe, and tolerable," said
The ACHIEVE II trial evaluated ubrogepant 50 mg and 25 mg, compared with placebo, across a wide range of clinical endpoints, including the co-primary endpoints of pain freedom (no pain) and freedom from the most bothersome migraine-associated symptom at two hours post-initial dose. For the two co-primary endpoints, ubrogepant 50 mg and 25 mg showed statistically significant higher response rates for pain freedom at two hours (21.8% for 50 mg, 20.7% for 25 mg and 14.3% for placebo), and the 50 mg dose demonstrated statistically significant higher response rates for the freedom from the most bothersome migraine-associated symptom at two hours (38.9% for 50 mg and 27.4% for placebo). Additionally, ubrogepant 50 mg was statistically superior to placebo in the absence of light sensitivity (43.8% for 50 mg and 35.5% for placebo) and sound sensitivity (54.1% for 50 mg and 46.3% for placebo).
Ubrogepant studies show that both the 50 mg and 25 mg doses were well tolerated with an adverse event profile similar to placebo. The most common adverse reaction during the single attack studies (occurring with an incidence greater than 2 percent and at least twice the rate of placebo) was nausea (incidence 2-4%). In a year-long extension study, the most common treatment-related adverse event was also nausea, with an incidence <2 percent.
"I have been living with migraine attacks for most of my life, but unfortunately, I can't tolerate existing prescription treatments when I start having pain," said
Triptans are the most popular acute treatment for migraine representing 70 percent of prescriptions. However, for people living with migraine disease, approximately 20 percent of individuals have multiple cardiovascular (CV) risk factors, and because triptans restrict blood vessels, they may not be appropriate for these migraine patients. And for those who take triptans, as many as 30 percent may not sufficiently respond or may experience side effects. In the ACHIEVE II trial, approximately 11 percent of participants had moderate to severe CV risk factors, and 23 percent of participants previously had an insufficient response to triptans.
"If approved, ubrogepant will provide a new and different acute treatment option for patients suffering the debilitating pain and other symptoms of migraine.
About ACHIEVE II (UBR-MD-02) Trial
The ACHIEVE II trial is a Phase 3, multicenter, double-blind, parallel-group study evaluating the efficacy, safety, and tolerability of ubrogepant (50 mg and 25 mg) compared to placebo for the acute treatment of a single migraine attack of moderate or severe headache pain intensity at home. In this pivotal trial, 1,355 adult patients (18-75 years of age) with a history of migraine (with or without aura) were randomized (1:1:1) to placebo, ubrogepant 25 mg, or ubrogepant 50 mg. The co-primary efficacy parameters were pain freedom (no pain) at two hours after the initial dose and absence of the most bothersome migraine-associated symptom at two hours after the initial dose. The most bothersome migraine-associated symptom could include photophobia, phonophobia, or nausea and was selected by the participant at the time of a qualifying migraine attack. Secondary efficacy endpoints also evaluated the clinical benefits of ubrogepant across a wide range of outcome measures, including pain relief at 2 hours, sustained pain relief from 2-24 hours, and sustained pain freedom from 2-24 hours, among others. Adverse events were collected and evaluated 48 hours after the initial and optional second dose of trial treatment, as well as within 30 days after administration of any dose.
Ubrogepant is a novel, highly potent, orally-administered CGRP receptor antagonist (gepant), in development for the acute treatment of migraine. CGRP and its receptors are expressed in regions of the nervous system associated with migraine pathophysiology. CGRP receptor antagonism is a completely new mechanism of action for the acute treatment of migraine compared to medications currently available, which include triptans (serotonin 1B/1D agonists), opioids and ergots.
Migraine is a chronic disease with episodic attacks defined by neurological symptoms such as headache pain, sensitivity to light and sound, and nausea; these symptoms are often debilitating. Migraine is highly prevalent, affecting approximately 31 million Americans, and is associated with significant disability leading to high personal, family, occupational, societal, and economic burden. Based on the current standard of care, there are still unmet needs for new acute treatments for migraine.
