US Real-World Effectiveness, Tolerability, and Healthcare Resource Utilization After Addition of Fremanezumab for Preventive Treatment in Patients Using Gepants for Acute Treatment of Migraine: Results From a Retrospective Chart Review.

Introduction: Fremanezumab, a monoclonal antibody (mAb) targeting the calcitonin gene-related peptide (CGRP) pathway, and gepants, small molecule CGRP receptor antagonists, are both approved for the treatment of migraine or its symptoms. This study assessed effectiveness, tolerability, and migraine-related healthcare resource utilization (HCRU) after the addition of fremanezumab for preventive migraine treatment in patients using gepants for acute treatment.

Methods: Data were extracted during a retrospective chart review from electronic medical records from the Dent Neurologic Institute.

Real-world Impact of Fremanezumab on Migraine-Related Health Care Resource Utilization in Patients with Comorbidities, Acute Medication Overuse, and/or Unsatisfactory Prior Migraine Preventive Response.

Introduction: Fremanezumab, a humanized monoclonal antibody targeting calcitonin gene-related peptide, is indicated for preventive treatment of migraine in adults. Real-world evidence assessing the effect of fremanezumab on migraine-related medication use, health care resource utilization (HCRU), and costs in patient populations with comorbidities, acute medication overuse (AMO), and/or unsatisfactory prior migraine preventive response (UPMPR) is needed.

Methods: Data for this US, retrospective claims analysis were obtained from the Merative MarketScan Commercial and supplemental databases.

Burden of migraine with acute medication overuse or psychiatric comorbidities and treatment with CGRP pathway-targeted monoclonal antibodies: A review.

Migraine is a complex and often debilitating neurological disease that affects more than 1 billion people worldwide. It is characterized by moderate-to-intense, throbbing headache attacks that are worsened by activity and is associated with nausea, vomiting, and sensitivity to light and sound. Migraine, ranked the second leading cause of years lived with disability by the World Health Organization, can diminish patients' quality of life and bring significant personal and economic burden.

Clinical characteristics and patient-reported outcomes of chronic and episodic migraine patients at a US tertiary headache center: A retrospective observational study.

Objective: To describe differences in clinical and demographic characteristics between patients with episodic migraine (EM) or chronic migraine (CM) and determine the effect of migraine subtype on patient-reported outcome measures (PROM).

Background: Prior studies have characterized migraine in the general population. While this provides a basis for our understanding of migraine, we have less insight into the characteristics, comorbidities, and outcomes of migraine patients who present to subspecialty headache clinics.

Commentary: Constipation caused by anti-calcitonin gene-related peptide migraine therapeutics explained by antagonism of calcitonin gene-related peptide's motor-stimulating and prosecretory function in the intestine.

Calcitonin gene-related peptide (CGRP) pathway-targeted treatments have been shown to be efficacious in the prevention of episodic and chronic migraine. Currently approved therapies include monoclonal antibodies (mAbs) that target CGRP (eptinezumab, fremanezumab, and galcanezumab) and the CGRP receptor (erenumab), and small molecule CGRP receptor antagonists (atogepant and rimegepant). While CGRP pathway-targeted treatments are generally well-tolerated, in a review article by Holzer and Holzer-Petsche published in the January 2022 issue of the authors discussed the role of the CGRP pathway in gastrointestinal physiology, with a specific focus on constipation associated with the use of CGRP pathway-targeted treatments.

Reducing the Burden of Migraine: Safety and Efficacy of CGRP Pathway-Targeted Preventive Treatments.

Migraine is a highly disabling and often chronic neurological disease that affects more than one billion people globally. Preventive migraine treatment is recommended for individuals who have frequent and/or disabling attacks; however, many of the medications used for migraine prevention (e.g.

A real-world study of acute and preventive medication use, adherence, and persistence in patients prescribed fremanezumab in the United States.

Background: Following approval of fremanezumab for the prevention of migraine in adults, health care decision makers are interested in understanding real-world clinical characteristics and treatment patterns among patients initiating fremanezumab therapy.

Methods: Data were obtained for this retrospective (pre-post) study from the Veradigm Health Insights database. The study period was January 1, 2014, to June 30, 2019.

Real-world impact of fremanezumab on migraine symptoms and resource utilization in the United States.

Background: Fremanezumab, a fully humanized monoclonal antibody (IgG2Δa) that selectively targets calcitonin gene-related peptide (CGRP), is approved for migraine prevention in adults. Real-world data on the effectiveness of fremanezumab are limited. This retrospective, observational cohort study assessed patient-reported migraine symptoms, health care resource utilization (HCRU), and direct medical costs before and after fremanezumab treatment initiation.

Recently, Gao et al. published an article titled "Monthly versus quarterly fremanezumab for the prevention of migraine: a systemic review and meta-analysis from randomized controlled trials" which concluded that monthly administration of fremanezumab led to significant reduction in monthly migraine days (MMD) when compared to quarterly fremanezumab. We have noted a critical flaw in Gao et al.

Immunogenicity of biologic therapies for migraine: a review of current evidence.

Background: Monoclonal antibodies (mAbs) targeting the calcitonin gene-related peptide (CGRP) pathway have been shown to be effective in migraine prevention. Eptinezumab, erenumab, fremanezumab, and galcanezumb have shown efficacy in clinical trials along with favorable safety and tolerability profiles. Although erenumab is a human mAb and the others have been humanized to varying degrees, they all have the capacity to provoke immune reactions.
