Safety and tolerability of atogepant for the preventive treatment of migraine: a post hoc analysis of pooled data from four clinical trials.

ABSTRACT:

Background

Conventional, non-specific preventive migraine treatments often demonstrate low rates of treatment persistence due to poor efficacy or tolerability. Effective, well-tolerated preventive treatments are needed to reduce migraine symptoms, improve function, and enhance quality of life. Atogepant is a migraine-specific oral calcitonin gene-related peptide receptor antagonist that is indicated for the preventive treatment of migraine in adults. This analysis evaluated the safety and tolerability profile of atogepant for the preventive treatment of migraine, including adverse events (AEs) of interest, such as constipation, nausea, hepatic safety, weight changes, and cardiac disorders.

Methods

This post hoc analysis was performed using data pooled from 2 (12-week) randomized, double-blind, placebo-controlled trials (RCTs) and 2 (40- and 52-week) open-label long-term safety (LTS) trials of oral atogepant for episodic migraine (EM).

Results

The safety population included 1550 participants from the pooled RCTs (atogepant, n = 1142; placebo, n = 408) and 1424 participants from the pooled LTS trials (atogepant, n = 1228; standard care [SC], n = 196). In total, 643/1142 (56.3%) atogepant participants and 218/408 (53.4%) placebo participants experienced ≥ 1 treatment-emergent AEs (TEAEs) in the RCTs. In the LTS trials, 792/1228 (64.5%) of atogepant participants and 154/196 (78.6%) of SC participants experienced ≥ 1 TEAEs. The most commonly reported TEAEs (≥ 5%) in participants who received atogepant once daily were upper respiratory tract infection (5.3% in RCTs, 7.7% in LTS trials), constipation (6.1% in RCTs, 5.0% in LTS trials), nausea (6.6% in RCTs, 4.6% in LTS trials), and urinary tract infection (3.4% in RCTs, 5.2% in LTS trials). Additionally, weight loss appeared to be dose- and duration-dependent. Most TEAEs were considered unrelated to study drug and few led to discontinuation.

Conclusions

Overall, atogepant is safe and well tolerated in pooled RCTs and LTS trials for the preventive treatment of EM in adults.

Project description:BackgroundThe humanized anti-CGRP monoclonal antibody eptinezumab has been evaluated in five large-scale clinical trials conducted in patients with migraine. This integrated analysis was conducted to evaluate the comprehensive safety and tolerability of eptinezumab in patients with migraine across these studies.MethodsData were pooled from four randomized, double-blind, placebo-controlled studies and the first year of one open-label study.ResultsThe pooled population comprised 2867 adults with migraine: eptinezumab, n = 2076 (4797 infusions); placebo, n = 791 (1675 infusions). A total of 1137/2076 (54.8%) patients who received eptinezumab and 414/791 (52.3%) patients who received placebo experienced ≥1 treatment-emergent adverse event (TEAE); rates were similar across eptinezumab dose groups (10-1000 mg). For most patients with TEAEs, the events were mild or moderate in severity and considered unrelated to study drug by the investigators. Thirty infusion-site AEs occurred in 27/2076 (1.3%) patients who received eptinezumab and 7 in 7/791 (0.9%) patients who received placebo. Infusion-site AEs led to infusion interruption in 19/2076 (0.9%) and 5/791 (0.6%) patients in the eptinezumab and placebo groups, respectively. Nasopharyngitis occurred in ≥2% of patients in the eptinezumab 300-mg group and with an incidence of at least 2 percentage points greater than in the placebo group; however, in most patients (eptinezumab, 139/140; placebo 40/41), its occurrence was considered not related to study treatment. Adverse events coded to hypersensitivity occurred for 23/2076 (1.1%) patients treated with eptinezumab and no patients in the placebo group. If additional TEAE terms that could indicate hypersensitivity are considered (e.g., urticaria, flushing/hot flush, rash, and pruritus), hypersensitivity reactions in the two pivotal placebo-controlled phase 3 studies occurred in ≥2% of patients in the eptinezumab 100-mg and 300-mg groups, and the incidence was at least 2 percentage points greater in either of these groups than in the placebo group. Most hypersensitivity reactions were not serious and resolved with standard medical treatment or observation without treatment, usually within 1 day.ConclusionsIn adults with migraine, the intravenous administration of eptinezumab every 12 weeks demonstrated a favorable safety and tolerability profile.Trial registrationClinicalTrials.gov (Identifiers: NCT01772524 , NCT02275117 , NCT02559895 , NCT02974153 , NCT02985398 ).

Project description:ObjectiveTo evaluate the safety and tolerability of aripiprazole adjunctive to standard antidepressant therapy (ADT) for patients with major depressive disorder (DSM-IV-TR criteria).MethodData from 2 identical studies of aripiprazole augmentation (8 weeks of prospective ADT treatment followed by 6 weeks of randomized double-blind adjunctive treatment) were pooled. The incidence of treatment-emergent adverse events (TEAEs) and weight, electrocardiogram (ECG), and laboratory measurements were assessed during the 6-week phase, including time course, severity, resolution, and predictors. The studies were conducted from June 2004 to April 2006 and September 2004 to December 2006.ResultsThe safety analysis included 737 outpatients (aripiprazole, n = 371; placebo, n = 366). The majority of patients completed the trials (aripiprazole, 86%; placebo, 88%). Common TEAEs (≥ 5% and twice the placebo rate) with aripiprazole were akathisia (25%), restlessness (12%), insomnia (8%), fatigue (8%), blurred vision (6%), and constipation (5%). Most TEAEs were of mild to moderate severity (aripiprazole, 89%; placebo, 95%). TEAE rates in the aripiprazole and placebo groups were not affected by ADT, age, or gender. Discontinuation due to TEAEs was low (aripiprazole, 3%; placebo, 1%). Mean weight change was higher with aripiprazole versus placebo (1.73 kg vs 0.38 kg, P < .001). At endpoint, clinical laboratory parameters, vital signs, and ECG indices (including QT(c) interval) were similar between groups. Akathisia with aripiprazole generally occurred in the first 3 weeks (76%), was of mild to moderate severity (92%), and led to discontinuation in 3 patients (0.8%). Within the aripiprazole group, age (18-40 years) was the only positive predictor for akathisia.ConclusionsIn this short-term post hoc analysis, aripiprazole as augmentation to ADT demonstrated a safety and tolerability profile similar to that in monotherapy studies in other psychiatric populations. Controlled long-term safety and efficacy data of aripiprazole as adjunctive to ADT are warranted.Trial registrationclinicaltrials.gov Identifiers: NCT00095823 (CN138-139) and NCT00095758 (CN138-163).

Project description:BackgroundErenumab, a fully human monoclonal antibody that targets the calcitonin gene-related peptide receptor, has demonstrated efficacy and safety in the prevention of episodic and chronic migraine. There exists an unmet need to establish the safety of erenumab in older individuals, in view of existing multiple comorbidities, polypharmacy, and age-related physiological changes. This pooled analysis of five large migraine-prevention studies examined the safety of erenumab stratified across age groups, particularly in older populations.MethodsPooled and age-stratified analysis of safety data from the 12-week double-blind treatment phase (DBTP) of five randomized, placebo-controlled Phase 2 and 3 studies of erenumab in participants with episodic or chronic migraine across the age groups < 40 years, 40-49 years, 50-59 years, and ≥ 60 years was completed. The safety of erenumab across age groups was determined by assessing safety endpoints including treatment-emergent adverse events (AEs), serious AEs, and events leading to study drug discontinuation.ResultsOverall, 3345 participants across five studies were randomized to receive either placebo (n = 1359), erenumab 70 mg (n = 1132) or erenumab 140 mg (n = 854); 3176 (94.9%) completed the DBTP, and 169 (5.1%) discontinued, mainly due to participant decision (110; 3.3%). Overall, 1349 (40.6%), 1122 (33.8%), and 850 (25.6%) participants received at least one dose of placebo, erenumab 70 mg, and erenumab 140 mg, respectively. Incidence of treatment-emergent AEs was similar across all age groups for both doses of erenumab (70 mg or 140 mg) and placebo (< 40 years, 44.0% vs 44.4%; 40-49 years, 42.5% vs 49.2%; 50-59 years, 46.5% vs 41.6%; ≥ 60 years, 43.8% vs 59.4%). Incidence of treatment-emergent serious AEs overall, and stratified by age groups for both doses and placebo was low (< 40 years, 0.9% vs 1.2%; 40-49 years, 1.7% vs 1.9%; and 50-59 years, 1.6% vs 1.1%), with no serious AEs reported in participants aged ≥ 60 years. No deaths were reported.ConclusionsErenumab (70 mg or 140 mg) exhibited a similar safety profile compared with placebo across age groups in individuals with episodic or chronic migraine, with no increased emergence of events due to age. Erenumab was well tolerated in older participants with multiple comorbidities, polypharmacy, and age-related physiological changes.Trial registration numberClinicalTrials.gov Identifiers: NCT02066415, NCT02456740, NCT02483585, NCT03096834, NCT03333109.

Project description:IntroductionUbrogepant is an oral, small-molecule calcitonin gene-related peptide receptor antagonist approved for the acute treatment of migraine. The efficacy and safety of ubrogepant were demonstrated in two pivotal phase 3, single-attack, randomized, placebo-controlled trials (ACHIEVE I and ACHIEVE II).MethodsWe conducted a post hoc analysis of pooled data from the ACHIEVE trials to evaluate the efficacy, safety, and tolerability of ubrogepant 50 mg (the only dose evaluated in both trials) versus placebo across a large population of participants with migraine. The coprimary efficacy outcomes were pain freedom and absence of the most bothersome migraine-associated symptom (including photophobia, phonophobia, and nausea) at 2 h post dose. Secondary outcomes included pain relief at 2 h post dose, sustained pain relief and pain freedom from 2 to 24 h, and absence of specific migraine-associated symptoms at 2 h post dose.ResultsA total of 2240 eligible participants were randomized to placebo (n = 1122) or ubrogepant 50 mg (n = 1118) in the ACHIEVE trials. Pain freedom at 2 h was reported in 13.0% of participants in the pooled placebo group and 20.5% in the pooled ubrogepant 50 mg group (odds ratio [OR] 1.72; 95% confidence interval [CI] 1.34, 2.22; P < 0.001). Absence of the most bothersome migraine-associated symptom at 2 h was reported by 27.6% in the pooled placebo group and by 38.7% in the pooled ubrogepant 50 mg group (OR 1.68; 95% CI 1.37, 2.05; P < 0.001). Adverse events (AEs) within 48 h after the initial or optional second dose were reported by 11.5 and 11.2% of participants in the pooled placebo and pooled ubrogepant 50 mg groups, respectively. The most common AE was nausea (1.8 and 1.9%, respectively). No serious AEs related to treatment or discontinuations due to AEs were reported.ConclusionThese results further support the efficacy, safety, and tolerability of ubrogepant for the acute treatment of migraine.Trial registrationClinicalTrials.gov Identifiers: ACHIEVE I: NCT02828020; ACHIEVE II: NCT02867709.

Project description:IntroductionRacial disparities in disease activity, clinical outcomes, and treatment survival persist despite advancements in rheumatoid arthritis (RA) therapies and clinical management. In this post hoc analysis of pooled data from the tofacitinib global clinical program, we evaluated the impact of race on the efficacy and safety of tofacitinib in patients with RA.MethodsData were pooled from 15 phase 2-3b/4 studies of patients with RA treated with tofacitinib 5 or 10 mg twice daily, adalimumab, or placebo. Outcomes were stratified by self-reported patient race (White/Black/Asian/Other). Efficacy outcomes to month 12 included: American College of Rheumatology (ACR)20/50/70 responses, Clinical Disease Activity Index (CDAI)/Disease Activity Score in 28 joints, erythrocyte sedimentation rate [DAS28-4(ESR)] low disease activity (LDA) rates, least squares (LS) mean change from baseline (∆) in CDAI, DAS28-4 (ESR), Health Assessment Questionnaire-Disability Index (HAQ-DI), and Pain [Visual Analog Scale (VAS)]. Odds ratios (ORs; 95% CI) versus placebo, and placebo-adjusted ∆LS means were calculated for active treatments using logistic regression model and mixed-effect model of repeated measurements, respectively. Safety outcomes were assessed throughout.ResultsA total of 6355 patients were included (White, 4145; Black, 213; Asian, 1348; Other, 649). For tofacitinib-treated patients, ORs for ACR20/50/70 responses and CDAI/DAS28-4(ESR) LDA rates through month 3 were generally numerically higher for White/Asian/Other versus Black patients. Across active treatments, trends toward higher placebo-adjusted improvements from baseline in CDAI, DAS28-4 (ESR), HAQ-DI, and Pain (VAS) were observed in Asian/Other versus White/Black patients. Numerically higher placebo responses in Black versus White/Asian/Other patients were generally observed across outcomes through month 12. Safety outcomes were mostly similar across treatment/racial groups.ConclusionsIn patients with RA, tofacitinib was efficacious across racial groups with similar safety outcomes; observed racial differences potentially reflect patient demographics or regional practice disparities.Trial registration numbersClinicalTrials.gov identifiers: NCT00147498; NCT00413660; NCT00550446; NCT00603512; NCT00687193; NCT01164579; NCT00976599; NCT01359150; NCT00960440; NCT00847613; NCT00814307; NCT00856544; NCT00853385; NCT01039688; NCT02187055.

Project description:Introduction In the early stage of schizophrenia (first 5 years), the most important clinical target besides symptom control is relapse prevention as each relapse significantly decreases the possibility of preferable long-term outcomes. Early discontinuation of antipsychotic medication due to intolerable side-effects is one of the most common causes of relapse. Objectives This poster aims to present cariprazine’s tolerability in the early stage of schizophrenia. Methods Data from 4 randomized, double-blind, placebo-controlled trials (NCT00404573, NCT01104766, NCT01104779, NCT00694707) with similar design (1 week of wash out period, 6 weeks of treatment and 2-4 weeks of follow-up) were pooled. For the post-hoc analysis, patients with early stage of schizophrenia (defined as having a disease duration of less than 5 years) were extracted from the whole safety population, and approved doses of cariprazine (1.5-6.0 mg/day) were combined. Treatment-emergent adverse events (TEAEs) and discontinuation rates were analysed versus placebo. Results Overall, 169 placebo- (PBO) and 322 cariprazine-treated (CAR) patients were identified as having schizophrenia for less than 5 years. 67.7% cariprazine- and 56.2% placebo-treated patients reported at least one TEAE; most frequently insomnia (10.9 % CAR; 12.4% PBO), akathisia (9.6% CAR; 2.4% PBO) and extrapyramidal symptoms (9.3% CAR; 1.8% PBO). Discontinuation due to adverse events was reported in only 8.4% of cariprazine- and 14.8% of placebo-treated patients. Relapse occurred in 3.1% of cariprazine- and 5.3% of placebo-treated patients. Conclusions Cariprazine was generally well-tolerated in the early stage of schizophrenia; given the limitations of this analysis, additional research is warranted.

Project description:BackgroundMigraine is one of the most common diseases worldwide while current treatment options are not ideal. New therapeutic classes of migraine, the calcitonin gene-related peptide (CGRP) antagonists, have been developed and shown considerable effectiveness and safety. The present study aimed to systematically evaluate the efficacy and safety of atogepant, a CGRP antagonist, for migraine prophylaxis from the results of randomized controlled trials (RCTs).MethodsThe Cochrane Library, Embase, PubMed and https://www.Clinicaltrialsgov/ were searched for RCTs that compared atogepant with placebo for migraine prophylaxis from inception of the databases to Feb 1, 2024. Outcome data involving efficacy and safety were combined and analyzed using Review Manager Software version 5.3 (RevMan 5.3). For each outcome, risk ratios (RRs) or standardized mean difference (SMD) were calculated.Results4 RCTs with a total of 2813 subjects met our inclusion criteria. The overall effect estimate showed that atogepant was significantly superior to placebo in terms of the reduction of monthly migraine (SMD - 0.40, 95% CI -0.46 to -0.34) or headache (SMD - 0.39, 95% CI -0.46 to -0.33) days, the reduction of acute medication use days (SMD - 0.45, 95% CI -0.51 to -0.39) and 50% responder rate (RR 1.66, 95% CI 1.46 to 1.89), while no dose-related improvements were found between different dosage groups. For the safety, significant number of patients experienced treatment-emergent adverse events (TEAEs) with atogepant than with placebo (RR 1.10, 95% CI 1.02-1.21) while there was no obvious difference between the five dosage groups. Most TEAEs involved constipation (RR 2.55, 95% CI 1.91-3.41), nausea (RR 2.19, 95% CI 1.67-2.87) and urinary tract infection (RR 1.49, 95% CI 1.05-2.11). In addition, a high dosage of atogepant may also increase the risk of treatment-related TEAEs (RR 1.64, 95% CI 1.02-2.63) and fatigue (RR 3.07, 95% CI 1.13-8.35).ConclusionsThis meta-analysis suggests that atogepant is effective and tolerable for migraine prophylaxis including episodic or chronic migraine compared with placebo. It is critical to weigh the benefits of different doses against the risk of adverse events in clinical application of atogepant. Longer and multi-dose trials with larger sample sizes are required to verify the current findings.

Project description:BackgroundMigraine is a neurological condition marked by frequent headaches, which tends to be accompanied by nausea and vomiting in severe instances. Injectable therapies for migraine, such as monoclonal antibodies that target calcitonin gene-related peptide (CGRP), have proven to be effective and safe. While various oral drugs are available, none have been developed for migraines. Patients prefer oral therapies because they are easier to use, making atogepant, an orally accessible small-molecule CGRP receptor antagonist, a possible alternative.ObjectivesThis systematic review and meta-analysis compared the safety and effectiveness of atogepant with placebo in treating migraine.MethodsAdhering to the PRISMA guidelines, we meticulously gathered randomized controlled trials (RCTs) from databases including the Cochrane Library, PubMed, Science Direct, and ClinicalTrials.gov. Studies comparing atogepant with placebo and reporting monthly migraine days (MMDs) as the primary outcome along with secondary outcomes such as monthly headache days and acute medication use days were included. Two independent reviewers conducted the data extraction and quality assessment. Statistical analyses were carried out using RevMan, utilizing risk ratios for dichotomous outcomes and mean differences for continuous outcomes, and a random-effects model.ResultsOur primary outcome was the change in MMDs over 12 weeks, which showed a significant reduction with atogepant at dosages of 10, 30, and 60 mg. Secondary outcomes, such as monthly headache days, proportion of patients achieving a ≥ 50% reduction in MMDs, acute medication use days, and patient-reported outcomes, consistently showed that atogepant outperformed placebo, highlighting its effectiveness in reducing the migraine burden.ConclusionHigher doses of atogepant are more effective in lowering migraine and headache-related days and increasing quality of life metrics. However, this is accompanied by an increased incidence of adverse events, suggesting the need for careful dose optimization to balance the benefits and risks.Systematic review registrationhttps://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=563395.
