A Study to Evaluate the Effectiveness and Safety of Dysport® for the Prevention of Episodic Migraine in Adults

Korábbi kezelés

• Use of any of the following medications in the specified timeframe prior to start of the screening daily headache eDiary:
  • Within 24 weeks
• i. CGRP antagonists (monoclonal antibody or gepant) for preventive treatment of migraine (acute treatment of headache/migraine with a gepant is permitted, but limited to no more than 6 days per month (i.e. 6 days per each 4-week period with gepant intake))
• i. Anaesthetic or steroid injection in any region targeted for injection with study intervention
• ii. Use of medical device to treat migraine (e.g. non-invasive neuromodulation therapies such as nerve stimulation (gammaCore), transcranial magnetic stimulation (cephaly), external trigeminal nerve stimulation, transcutaneous electrical nerve stimulation, and peripheral neuroelectrical stimulation)
• iii. Other interventions for migraine assessed to interfere with study evaluations (e.g. acupuncture in head and neck region, cranial traction, nociceptive trigeminal inhibition, occipital nerve block treatments, and dental splints for headache) iv. Use of opioids or barbiturates for more than 2 days/month.
  • Note: participants are permitted to take one concomitant migraine preventative treatment (not listed above); however, the dose of this medication should be stable for ≥3 months before start of the screening eDiary.

Más betegség

• Headache attributed to another disorder (e.g. secondary headaches), except medication overuse headache, which is permitted.
• Known history of treatment failure to more than four medications prescribed for the prevention of migraine (two of which have different mechanisms of action) or known history of treatment failure to botulinum toxin prescribed for the prevention of migraine
