This prevalence meets criteria established by both the US Food and Drug Administration and European Medicines Agency for rare disease designation. The rarity of CCH creates substantial clinical and research challenges, including prolonged diagnostic delays, limited research funding and a dearth of approved treatments. The economic burden is particularly notable, with annual costs exceeding €20,000 per patient.

This is the first report on one-year outcomes in participants with chronic migraine (CM) and in the EM population with prior preventive treatment failures. Here, we report the long-term safety, tolerability, efficacy and functional outcomes of one-year preventive treatment of EM or CM with atogepant.MethodsThis is an interim analysis of an ongoing, open-label, multicenter, 156-week, safety extension study that enrolled completers from phase 3 PROGRESS and ELEVATE trials. The participants completing week 52 or early termination were evaluated. Eligible adults with at least a one-year history of migraine, with either CM (PROGRESS) or EM who previously had inadequate response to two to four classes of conventional oral preventive treatments (ELEVATE). All participants received atogepant 60 mg once daily. The primary outcome was safety and tolerability of atogepant. Efficacy and functional outcomes were prespecified exploratory analyses.ResultsOf 596 participants, 595 (PROGRESS, n = 325; ELEVATE, n = 270) were treated and included in the safety population and 524 (PROGRESS, n = 284; ELEVATE, n = 240) were included in the modified intent-to-treat population. In this interim analysis, mean duration of atogepant exposure was 496.5 days. Treatment-emergent adverse events (TEAEs) occurred in 79.0% of participants; most were mild/moderate and not related to atogepant. Common TEAEs (≥5%) included COVID-19 (28.7%), nasopharyngitis (10.9%) and constipation (8.2%). TEAEs leading to discontinuation occurred in 5.9% of participants. One death attributed to asphyxia by housefire was observed. Other serious TEAEs occurred in 5.5% of participants and none were related to atogepant. Alanine aminotransferase and/or aspartate aminotransferase ≥3× upper limit of normal occurred in two participants; neither met Hy's law criteria. Improvements in efficacy and functional outcomes from lead-in study baseline were observed at weeks 13-16 in this open-label study and were consistent through 48 and 52 weeks, respectively.ConclusionsOverall safety results were consistent with the known safety profile of atogepant and the drug was well-tolerated over the course of the study. No new safety signals were identified.

Individuals diagnosed with migraine were enrolled from September 2020 to June 2022. Participants underwent semi-structured interviews to record their usual trigger factors, premonitory symptoms, non-headache symptoms during the headache and postdromal symptoms. The primary outcome was to assess whether reporting specific trigger factors increased the likelihood of experiencing corresponding premonitory symptoms. Furthermore, the presence of non-headache symptoms across migraine phases was examined.ResultsAmong the 632 participants (mean age 44.6 ± 12.0 years; 89% female), the most frequent triggers were sleep disturbances (70.1%), stress (67.7%) and alcohol consumption (59.0%). Common premonitory symptoms included tiredness (39.9%), concentration difficulties (35.0%) and neck pain (33.2%). Significant associations were found between specific triggers and premonitory symptoms: bright light with premonitory photophobia (odd ratio (OR) = 2.79; 95% confidence interval (CI) = 1.90-4.12; <i>p</i> < 0.001), loud noise with premonitory phonophobia (OR = 4.26; 95% CI = 2.77-6.59; <i>p</i> < 0.001) and sleep disturbances with premonitory tiredness (OR = 1.74; 95% CI = 1.15-2.64; <i>p</i> = 0.009).ConclusionsOur results reveal a notable overlap between specific migraine triggers and corresponding premonitory symptoms, implicating that some perceived triggers could be early signs of an impending attack.

A phase 2 trial was carried out in treatment-resistant participants with chronic migraine (CM) (n = 16) or episodic migraine (EM) (n = 22).

Although most patients with headaches are managed in primary care settings, including chiropractic clinics, there are few studies describing the prevalence of headache and headache diagnoses in primary care. The present study aimed to: (1) estimate the prevalence of headache consultations in chiropractic practice; (2) estimate the prevalence of different headache diagnoses used in chiropractic practice; and (3) determine the association between the prevalence of headache consultations and chiropractor characteristics.MethodsAll chiropractors in Denmark, who were members of the Danish Chiropractic Association, (n = 695) were invited to participate. Data collection for this cross-sectional study was based on a survey and a 20-day logbook and took place in 2022. The survey collected information on various characteristics of the chiropractors who completed the logbook. The logbook recorded the total number of consultations, whether the reason for the consultation was related to headache, the type of diagnosis, the type of consultation (e.g. new patient, maintenance care), and whether the headache was the primary or secondary reason for the consultation. We used weighted linear regression analyses with robust standard errors for determining associations between prevalence and chiropractor characteristics.ResultsIn total, 76 chiropractors participated, reporting a prevalence of 12% for consultations including any type of headache. The response rate was 10.9%. The prevalence of headache-related consultations per chiropractor varied from 0% to 38% (median = 12.1; interquartile range = 8.2-15.5). In 43.6% of all headache consultations, headache was the main reason for consulting a chiropractor. The most common type of headache was tension-type (36.2%), followed by combinations of headache types (34.4%), with the most common combination being tension-type and cervicogenic headache. Headaches were reported in 12% of all new consultations and 25% of all maintenance care consultations. There were no associations between the prevalence of headache consultations and chiropractor characteristics.ConclusionsPatients with headaches, especially tension-type headaches and patients with more than one type of headache, were common in chiropractic clinics, with 12% of all consultations related to headaches. In two out of every five consultations related to headaches, the headache itself was the primary reason for visiting the chiropractor, rather than a secondary symptom accompanying another condition such as neck pain<b>.</b> No specific characteristics of chiropractors were associated with the frequency of headache consultations.
