PRIME-Teen—Treatment Persistence and Outcomes Associated with CGRP Monoclonal Antibodies Compared with Conventional Oral Preventives in Adolescents with High-Burden Migraine: An Exploratory Real-World Analysis from the German Pain e-Registry (GPeR)
Abstract
Background: Adolescent migraine is highly prevalent and associated with substantial functional and psychosocial burden. Conventional oral preventives are widely used off-label with limited pediatric efficacy and frequent tolerability problems. Real-world data on calcitonin gene-related peptide (CGRP) monoclonal antibodies in adolescents are scarce. Methods: We conducted an exploratory, retrospective cohort analysis of depersonalized routine-care data from adolescents with migraine in the German Pain e-Registry. Patients were eligible if they had at least one 6-month episode with high-evidence conventional oral preventives (HECP) and one 6-month episode with a CGRP monoclonal antibody (CGRP-mAb), each with baseline and follow-up documentation, enabling intra-individual descriptive comparisons. The primary endpoint was a pragmatic composite of 6-month treatment persistence and ≥50% reduction in monthly migraine days (MMD). Secondary outcomes included MMD, MMD with acute medication (MMDAM), migraine-related sick-leave days (MMSLD), disability (MIDAS), and patient-reported psychosocial outcomes. Results: A total of 422 adolescents contributed 1448 HECP and 422 CGRP-mAb episodes. Premature discontinuation occurred in 68.8% (HECP) and 11.9% (CGRP-mAb) of episodes; corresponding 6-month persistence was 30.6% and 88.2%, respectively. Mean MMD decreased from 11.7 to 9.4 during HECP episodes and from 11.6 to 4.4 during CGRP-mAb episodes. A ≥50% MMD reduction occurred in 25.4% (HECP)…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 422 participants or records.
