In Treatment Period 1, participants took atogepant 60\u2009mg once daily (QD) for 12\u2009weeks and their own non\u2010gepant acute headache medication for breakthrough migraine attacks. In Treatment Period 2, participants continued taking atogepant 60\u2009mg QD and ubrogepant 100\u2009mg was taken as needed (PRN) for the treatment of breakthrough migraine attacks (up to eight per 4\u2010week interval) for 12\u2009weeks. In Treatment Period 2, an optional second ubrogepant dose or the participant's own acute medication could be used to rescue headaches that did not resolve within 2\u201324\u2009h post initial ubrogepant dose. The primary objective evaluated the safety and tolerability of the concomitant use of ubrogepant and atogepant.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Of 263 participants enrolled, 262 were treated in Treatment Period 1 (Safety Population 1) and 218 continued and were treated in Treatment Period 2 (Safety Population 2). The mean (standard deviation) number of ubrogepant use days in Treatment Period 2 was 6.6\u2009(5.03) over the 12\u2009weeks. In Treatment Periods 1 and 2, 49.6% and 43.1% of participants experienced a treatment\u2010emergent adverse event (TEAE), respectively. The most common TEAEs (\u22655%) in Treatment Period 1 and Treatment Period 2 were COVID\u201019 (8.4%, 3.2%), fatigue (6.5%, 1.4%), nausea (6.1%, 0.9%), decreased appetite (5.7%, 0.9%), and constipation (5.3%, 0.9%). In Treatment Period 2, no increase in the incidence and types of TEAEs in relation to the number of ubrogepant use days or doses taken were identified. During the whole treatment period, 9.9% of participants discontinued atogepant or ubrogepant treatment due to TEAEs. There was one serious TEAE in Treatment Period 1 (ureterolithiasis) and one in Treatment Period 2 (cervical myelopathy), and both were considered not related to study treatment by the study investigators.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The use of atogepant 60\u2009mg QD for the preventive treatment of EM and ubrogepant 100\u2009mg PRN for the acute treatment of migraine over the 12\u2010week open\u2010label concomitant use treatment period was safe and well tolerated.
