What side effects are associated with this type of intervention?

Common treatments for migraines, particularly CGRP inhibitors like Fremanezumab, often include side effects such as injection site reactions (pain, redness, or swelling), constipation, and muscle cramps or spasms. Other treatments for migraines, such as triptans, can cause dizziness, fatigue, dry mouth, and, in rare cases, more serious cardiovascular issues. Non-invasive neuromodulation devices may cause mild adverse events like tingling, warmth, or numbness in the treated area. It is important to discuss these potential side effects with a healthcare provider to determine the most appropriate treatment.

What prior FDA approvals exist?

The FDA has approved several treatments for migraine, including CGRP inhibitors similar to fremanezumab. Notable CGRP inhibitors include erenumab (Aimovig), galcanezumab (Emgality), and eptinezumab (Vyepti). These medications work by targeting the calcitonin gene-related peptide (CGRP) pathway, which plays a crucial role in migraine pathophysiology. Additionally, triptans such as sumatriptan and zolmitriptan have been widely used for acute migraine treatment. These drugs offer various administration routes, including oral, subcutaneous, and intranasal, providing flexibility in managing migraine attacks.

What other types of research exist?

Promising novel alternatives to Fremanezumab for migraine treatment in 2024 include other CGRP receptor antagonists such as Eptinezumab and Galcanezumab. Additionally, Lasmiditan, a serotonin (5-HT1F) receptor agonist, and new formulations of triptans like Zolmitriptan and Sumatriptan are also noteworthy options.

Summary

This trial is testing an injectable medication called fremanezumab to prevent migraines in children and teenagers aged 6 to 17. The medication works by blocking signals in the brain that cause headaches. Fremanezumab has been investigated for the preventive treatment of migraine in adults.

Who is the study for?

This trial is for children and adolescents aged 6 to 17 who have migraines. They must have been part of previous related studies, be in good health, not pregnant or nursing, without significant medical history like hemiplegic migraine or severe allergies to proteins. Participants need to weigh at least 17 kg and meet certain vaccine requirements.

What is being tested?

The study tests the long-term safety and effectiveness of a medication called Fremanezumab when injected under the skin as a preventive treatment for migraines in young participants. The trial will last up to five years.

What are the potential side effects?

While specific side effects are not listed here, Fremanezumab may cause reactions at the injection site, flu-like symptoms, allergic reactions or other potential side effects which will be closely monitored throughout the study.

Mechanism Of Action

Side Effect Profile

Other Research

Migraine treatments work through various mechanisms to alleviate symptoms and prevent attacks. CGRP inhibitors, like Fremanezumab, block the activity of the calcitonin gene-related peptide (CGRP), a molecule involved in migraine pathophysiology, thereby reducing inflammation and pain transmission. Triptans, another common treatment, activate serotonin receptors (5-HT1B/1D) to constrict blood vessels and inhibit the release of pro-inflammatory neuropeptides. NSAIDs, such as diclofenac, reduce inflammation and pain by inhibiting cyclooxygenase enzymes (COX-1 and COX-2). Understanding these mechanisms is crucial for migraine patients as it helps in selecting the most effective treatment tailored to their specific migraine triggers and symptoms, potentially improving their quality of life.
