Patient-reported outcomes, health-related quality of life, and acute medication use in patients with a ≥ 75% response to eptinezumab: subgroup pooled analysis of the PROMISE trials.

ABSTRACT:

Background

PROMISE-1 and PROMISE-2 evaluated the preventive efficacy, tolerability, and safety of eptinezumab, a calcitonin gene-related peptide-targeted monoclonal antibody, in adults with episodic (EM) and chronic migraine (CM), finding significant reductions in migraine frequency. This post hoc analysis compared patient-reported outcomes (PROs), health-related quality of life (HRQoL) and acute medication use in patients with a ≥ 75% migraine responder rate (MRR) after treatment with eptinezumab to patients with a ≥ 50- < 75% MRR.

Methods

PROMISE-1 and PROMISE-2 were phase 3, randomized, double-blind, placebo-controlled studies. This analysis included patients from both studies treated with eptinezumab 100 mg or 300 mg who experienced ≥ 75% and ≥ 50-< 75% MRR over Weeks 1-12 (wks1-12). In both studies, HRQoL was measured by the 36-item Short-Form Health Survey (SF-36) and acute medication usage. PROMISE-2 also included the 6-item Headache Impact Test (HIT-6), patient-identified most bothersome symptom (PI-MBS), and Patient Global Impression of Change (PGIC).

Results

In PROMISE-1, a total of 115/443 (26.0%; 100 mg, n = 49, 300 mg, n = 66) and 120/443 (27.0%; 100 mg, n = 61, 300 mg, n = 59) eptinezumab-treated patients achieved ≥ 75% and ≥ 50-< 75% MRR over wks1-12, respectively. In PROMISE-2, a total of 211/706 (30.0%; 100 mg, n = 95; 300 mg, n = 116) and 209/706 (29.6%; 100 mg, n = 110, 300 mg, n = 99) eptinezumab-treated patients achieved ≥ 75% and ≥ 50-< 75% MRR over wks1-12, respectively. EM and CM patients with ≥ 75% and ≥ 50-< 75% MRR over wks1-12 showed reduced use of acute headache medication and increased HRQoL to normative levels across SF-36 domains of bodily pain, social functioning, and physical functioning. In CM patients with ≥ 75% and ≥ 50-< 75% MRR over wks1-12, the mean change in HIT-6 total score with eptinezumab (pooled) was - 11.7 and - 7.6, respectively. "Very much" or "much" improvement responses were reported in 41.8% and 16.5% on PI-MBS and 36.2% and 20.0% on PGIC in ≥ 75% and ≥ 50-< 75% MRR, respectively.

Conclusion

Eptinezumab treatment induced a ≥ 75% MRR over wks1-12 in the majority of patients. This patient subgroup reported substantial improvements in PROs associated with headache-related life impact and HRQoL, and reductions in acute headache medication use, which were more marked than those in the ≥ 50-< 75% responders. This study supports the clinical meaningfulness of ≥ 75% MRR for patients with either EM or CM.

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:BackgroundPatients with chronic migraine (CM) treated with eptinezumab in the PROMISE-2 trial achieved greater reductions in migraine and headache frequency, impact, and acute headache medication (AHM) use than did patients who received placebo. This post hoc analysis examines relationships between headache frequency reductions and changes in AHM use in patients in PROMISE-2.MethodsPROMISE-2 was a double-blind, placebo-controlled trial conducted in adults with CM. Patients were randomized to eptinezumab 100 mg, 300 mg, or placebo, administered intravenously once every 12 weeks for up to two doses. Patients recorded headache/AHM information daily and for each event in an electronic diary; data from all days with daily reports were included. Shifts in headache frequency and AHM use were assessed in the three populations: total CM population, patients with CM and medication-overuse headache (MOH), and patients with CM and MOH who were ≥ 50% responders during treatment (response over weeks 1-24).ResultsA total of 1072 adults with CM received treatment (eptinezumab, n = 706; placebo, n = 366). Mean baseline headache frequency was 20.5 days; mean baseline AHM days was 13.4; 431 patients had MOH, of which 225 (52.2%) experienced ≥50% response over weeks 1-24. Relative to baseline, the proportion of days with both headache and AHM use decreased 25.1% (eptinezumab) versus 17.0% (placebo) in the total population (N = 1072), 29.2% versus 18.4% in the MOH subpopulation (n = 431), and 38.3% versus 31.5% in the CM with MOH population with ≥50% response subgroup (n = 225) during weeks 1-24. The proportion of days with headache and triptan use decreased 9.1% (eptinezumab) versus 5.8% (placebo), 11.8% versus 7.2%, and 14.5% versus 12.6%, respectively. Reductions in other AHM types were smaller.ConclusionsIn this post hoc analysis, eptinezumab use in patients with CM was associated with greater decreases in days with headache with AHM overall and with triptans in particular. The magnitude of effect was greater in the subgroup of CM patients with MOH and ≥ 50% response.Trial registrationClinicalTrials.gov Identifier: NCT02974153 . Eptinezumab reduces headache frequency and acute medication use in patients with chronic migraine.

Project description:BackgroundEptinezumab 100 mg and 300 mg met the primary efficacy endpoint in both PROMISE clinical trials, significantly reducing frequency of monthly migraine days over Weeks 1‒12. The objective of this analysis was to assess the clinical response to eptinezumab 100 mg and 300 mg within the pivotal phase 3 PROMISE-1 and PROMISE-2 studies to potentially identify subsets of patients with meaningful differences between doses.MethodsPatients from PROMISE-1 (NCT02559895) and PROMISE-2 (NCT02974153) trials were divided into subgroups based on demographic and migraine characteristics, and baseline questionnaire responses. For each subgroup, the overall likelihood of achieving ≥ 50% migraine responder rate (MRR) over Weeks 1-12 and Weeks 13-24 with either eptinezumab 100 mg or 300 mg was calculated using odds ratios (with associated confidence intervals) and compared.ResultsIn PROMISE-1 (episodic migraine) and PROMISE-2 (chronic migraine), the likelihood of achieving ≥ 50% MRR over Weeks 1-12 and Weeks 13-24 was roughly equivalent for patients receiving either dose level of eptinezumab. Given the number of comparisons performed, sporadic apparent differences were seen but no replicated patterns between studies emerged. In PROMISE-1, no differences were observed in any subgroup over Weeks 1-12. In PROMISE-2, patients reporting < 15 monthly migraine days at baseline, any problems with mobility per the EQ-5D-5L, or a social functioning score > 45.0 per the 36-item Short-Form Health Survey (SF-36), appeared more likely to achieve ≥ 50% MRR with 300 mg over Weeks 1-12, with none of these being apparent in PROMISE-1.ConclusionsOverall, these data suggest that across PROMISE-1 and PROMISE-2, there were no meaningful differences in the likelihood of achieving ≥ 50% MRR between the eptinezumab dose levels in the majority of patient subgroups. In the few subgroups that displayed small, but potentially meaningful differences, patients were more likely to achieve ≥ 50% MRR with eptinezumab 300 mg; however, minimal consistency across both studies and time periods was noted.Trial registrationClinicalTrials.gov.

Project description:BackgroundSubgroup analyses are widely used to evaluate the heterogeneity of treatment effects in randomized clinical trials. However, there is a limited investigation of the quality of prespecified and reported subgroup analyses in stroke trials. This study evaluated the credibility of subgroup analyses in stroke trials.Methods and analysisWe searched Medline/PubMed, Embase, the Cochrane Central Register of Controlled Trials, and the Web of Science from inception to 24 March 2021. Three reviewers screened, extracted, and analyzed the data from the publications. Primary publications of stroke trials that reported at least one subgroup effect and had published corresponding study protocols were included. The Instrument for Assessing the Credibility of Effect Modification Analyses (ICEMAN) was used to examine the quality of the subgroup effects reported, with each subgroup effect assigned a credibility rating ranging from very low to high. Subgroup effects with two or more "definitely no" responses received a low credibility rating. The risk of bias was assessed using the Cochrane Risk-of-Bias tool for randomized trials version 2.ResultsSeventy-four articles met the inclusion criteria and reported a combined total of 647 subgroup effects. The median sample size was 1264 (interquartile range (IQR): 380-3876), and the median number of subgroups prespecified in the protocol was 6 (IQR: 2-10). Sixty-one (82%) studies used the univariate test of interaction. Of the total 647 subgroup effects reported in these studies, 319 (49%) were reported in acute stroke trials, while 423 (65%) had low credibility.ConclusionThe quality of subgroup analysis reporting in stroke trials remains poor. More effort is needed to train trialists on the best methods for designing and performing subgroup analyses, and how to report the results.Trial registration numberWe prospectively registered the review with International Prospective Register for Systematic Reviews (registration number: CRD42020223133).
