Effect of Ivabradine on Migraine Symptoms Induced by Levcromakalim

Effect of Ivabradine on Levcromakalim-Induced Symptoms in Individuals With Migraine Without Aura: A Randomized Double-Blind Two-Way Crossover Study

Not applicable Interventional Danish Headache Center · NCT04853797

This study is testing if Ivabradine can help reduce migraine symptoms caused by Levcromakalim in people who have migraines without aura.

What this trial studies

This study investigates how Ivabradine affects migraine symptoms triggered by Levcromakalim in individuals diagnosed with migraine without aura. The research focuses on the role of hyperpolarization-activated cation (HCN) channels in migraine pathophysiology, particularly how their activity may be influenced by cyclic nucleotides and potassium channel activation. Participants will receive either Ivabradine, Levcromakalim, or a placebo to assess the drug's efficacy in alleviating migraine symptoms. The findings aim to enhance understanding of migraine mechanisms and inform future drug development.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-60 with a diagnosis of episodic migraine without aura and in good general health.

Not a fit: Patients with tension-type headaches or significant comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more effective treatments for individuals suffering from migraine without aura.

How similar studies have performed: While the specific approach of using Ivabradine in this context is novel, previous studies have explored the role of HCN channels in migraine, indicating potential for success.

* Have a history of personal/familial or clinical signs of: cardiovascular and cerebrovascular disease (Long QT Syndrome, Cardiac dysrhythmia, Bradycardia, i.e. a resting heart rate of \< 60 bpm at screening, Amnestic information or clinical signs of hyper- or hypotension (Hypertension (systolic blood pressure \> 150 mmHg and / or diastolic blood pressure \> 100 mmHg)/Hypotension (systolic blood pressure \< 90 mm Hg and / or diastolic blood pressure \< 50 mmHg)), Heart failure (NYHA II or higher)); Psychiatric conditions; Drug abuse of any kind; Smoking; Other comorbidities or clinical signs of diseases of any kind considered by the investigating physician to make the participant ineligible because of safety concerns).
* Are pregnant, breastfeeding or not using appropriate contraception.
* Do not want any information on significant pathological findings in the study.
