Atogepant vs Topiramate for Migraine
(ATO-TOPIRAMATE Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests two treatments, atogepant and topiramate, to evaluate their effectiveness and safety in preventing migraines. Atogepant is already used for occasional migraine prevention, while topiramate is another approved migraine prevention medication. Participants will initially use either atogepant or topiramate for 24 weeks and, if eligible, will receive atogepant for an additional 52 weeks. The trial seeks individuals who have experienced migraines for at least a year and have at least four migraine days each month. As a Phase 3 trial, this study is the final step before FDA approval, allowing participants to contribute to the availability of new migraine treatments.
Do I need to stop my current medications for the trial?
The trial information does not specify if you need to stop your current medications. However, since the study involves taking either atogepant or topiramate, it's possible that changes to your current migraine treatment may be required. Please consult with the trial coordinators for specific guidance.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research shows that both atogepant and topiramate have undergone studies for safety and tolerability in treating migraines.
For atogepant, studies indicate it is generally well-tolerated. Common side effects include nausea, constipation, and fatigue. Importantly, no major differences in side effects appeared between atogepant and a placebo, suggesting safety. Long-term studies found no new safety issues, and most participants experienced fewer migraine days.
Topiramate is also considered generally safe for adults. The most common side effects are tingling sensations and changes in taste. However, topiramate should not be used during pregnancy unless effective birth control is in place, as it can harm the unborn baby.
Both medications have approval for preventing migraines, further supporting their safety for this purpose.12345Why are researchers excited about this trial's treatments?
Researchers are excited about atogepant for migraines because it offers a novel approach by targeting the CGRP (calcitonin gene-related peptide) pathway, which plays a key role in migraine development. Most traditional migraine treatments, like triptans and beta-blockers, work by constricting blood vessels or altering neurotransmitter activity. Atogepant, on the other hand, prevents migraines by blocking CGRP receptors, potentially offering better tolerance and fewer side effects. Meanwhile, topiramate, an existing option used for migraine prevention, is being compared to see how atogepant stacks up in terms of effectiveness and safety. This exploration could lead to more personalized and effective migraine management strategies.
What evidence suggests that this trial's treatments could be effective for migraine?
Research shows that atogepant, which participants in this trial may receive, reduces the number of migraine days. In one study, 64.1% of people taking atogepant experienced a reduction of migraine days by half or more. Another study found that people taking atogepant had fewer migraine days each month, with benefits observed at different doses. Similarly, topiramate, another treatment option in this trial, effectively prevents migraines. Studies have shown that it significantly reduces headache frequency and is generally well-tolerated. Both treatments have strong evidence supporting their effectiveness in preventing migraines.26789
