Symbravo Approved for Migraine Treatment
Axsome Therapeutics has received approval from the U.S. Food and Drug Administration (FDA) for Symbravo, a combination of meloxicam and rizatriptan, designed for the acute treatment of migraines with or without aura in adults.
Clinical Trials and Efficacy
The FDA’s decision was based on robust data from three Phase III trials encompassing over 21,000 migraine attacks. In the MOMENTUM trial, which targeted migraines of moderate to severe intensity, Symbravo demonstrated a statistically significant improvement in achieving pain relief and alleviating the most bothersome symptoms—photophobia, phonophobia, and nausea—within two hours of dosing compared to placebo. This relief was sustained for many patients over 24 and 48 hours.
In the INTERCEPT trial, Symbravo was evaluated in cases where the initial migraine pain was mild. Results mirrored those of the MOMENTUM trial, showcasing the drug’s consistent efficacy across different migraine severities.
The MOVEMENT trial, an open-label long-term safety study involving 706 patients who experienced at least two migraines per month, further supported Symbravo’s safety profile. The most commonly reported adverse effects were somnolence and dizziness.
Company Statement
Dr. Herriot Tabuteau, CEO of Axsome Therapeutics, emphasized the drug’s impact, stating, “Migraine attacks strike without warning and disrupt the lives of an estimated more than 39 million patients in the U.S. alone. Symbravo provides patients and clinicians with an important new option which can quickly stop a migraine attack, keep it away, and allow patients to resume their normal activities, with just a single dose.”

The FDA’s approval of Symbravo, combining meloxicam and rizatriptan, introduces a novel approach to migraine management, but several aspects warrant closer scrutiny.
Ingredient Synergy and Efficacy: Meloxicam, a nonsteroidal anti-inflammatory drug (NSAID), and rizatriptan, a serotonin receptor agonist, tackle migraines from different angles—meloxicam reducing inflammation and rizatriptan constricting blood vessels. While this combination theoretically offers a dual-action benefit, the clinical trials primarily highlight short-term efficacy without thoroughly exploring comparative effectiveness against existing mono or combination therapies. Are we looking at a genuine breakthrough or merely a repackaged solution?
Safety Profile and Side Effects: Although the MOVEMENT trial’s results suggest a favorable safety profile, somnolence and dizziness are notable side effects, particularly for a medication marketed as enabling patients to “resume their normal activities.” The long-term implications of combining an NSAID with a triptan, especially concerning cardiovascular and gastrointestinal risks, remain underexplored. For patients with pre-existing conditions, this could be a double-edged sword.
Market Positioning and Patient Accessibility: With over 39 million migraine sufferers in the U.S., Symbravo’s market potential is substantial. However, pricing, insurance coverage, and the availability of generic alternatives will significantly influence its adoption. Moreover, the convenience of a single-dose treatment is appealing, but it begs the question: will this be cost-effective compared to established treatments like sumatriptan or naproxen?
Future Outlook: While Symbravo offers a promising new option for migraine sufferers, its long-term safety, comparative efficacy, and cost-effectiveness will determine its standing in a crowded migraine treatment landscape. Clinicians and patients alike should remain cautiously optimistic, balancing the excitement of a new treatment with the practicalities of real-world use.
