Calcitonin gene\u2013related peptide has been linked to the pathophysiology of both obesity and migraine. Weight loss with atogepant, a calcitonin gene\u2013related peptide receptor antagonist indicated for the preventive treatment of migraine, has been observed during the 12\u2010week EM and CM trials, as well as in long\u2010term (40\u2010 or 52\u2010week) EM trials. Long\u2010term effects of atogepant on body weight in participants with increased migraine burden (i.e., EM or CM) have not been reported.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>In this interim analysis of a safety endpoint from study 312, a phase 3, open\u2010label, extension study, weight loss was assessed in the overall population and by prior participation in each lead\u2010in study (12\u2010week double\u2010blind treatment period): PROGRESS (phase 3, multicenter, randomized, controlled study in CM) or ELEVATE (phase 3, multicenter, randomized, controlled study in EM treatment failure). Change from baseline in body weight at each study visit through end of treatment (PROGRESS and ELEVATE) or up to week 52 (study 312) was assessed (safety endpoint). Proportions of participants with \u22655% weight loss at any time, at the end of the lead\u2010in study, or at week 52 in study 312 were evaluated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Participants from PROGRESS (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u2009325) and ELEVATE (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u2009270) rolled over to study 312 (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u2009595) and were treated with atogepant 60\u2009mg once daily. In study 312, mean (standard deviation) body weight decreased over time (\u22122.16\u2009kg [5.89\u2009kg; \u22124.76\u2009lb] at week 52), with 44.8% (265\/592) of participants experiencing a \u22655% weight loss at any time during the study and 29.5% (140\/474) experiencing a \u22655% weight loss at week 52. In study 312, weight loss from lead\u2010in study baseline was evident as early as week 4 and appeared to plateau around weeks 28 to 36, reaching a maximum numerical weight loss at week 44. Higher baseline body mass index was associated with greater odds of achieving \u22655% weight loss both at any time and at week 52. No significant effect of sex, race, adverse drug reactions, or therapeutic response to treatment was observed.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Participants receiving atogepant 60\u2009mg once daily for long\u2010term preventive treatment of migraine were observed to have a decrease in mean body weight after 1\u2009year of open\u2010label treatment. Approximately 30% of participants experienced a clinically meaningful (\u22655%) weight loss threshold after 1\u2009year of open\u2010label treatment.
