Electronic Drug Patch for Acute Migraines Approved in U.S.
The ZECUITY is a single use battery powered patch that delivers sumatriptan through the skin at the press of a button. It uses an electric current to pull ionized drug particles through the skin while monitoring the skin’s resistance to the transfer of sumatriptan during the the four-hour dosing.
From the announcement:
Zecuity was approved based upon an extensive development program with phase 3 trials that included 800 patients using more than 10,000 Zecuity patches. In these trials, Zecuity was proven safe and effective at treating migraine and relieving its cardinal symptoms (headache pain, migraine-related nausea and sensitivity to light and sound) two hours after patch activation.
In the phase 3 pivotal study, twice as many patients treated with Zecuity achieved freedom from headache pain at two hours compared with placebo (18% and 9%, respectively). Additionally, 53% of patients treated with Zecuity achieved relief from headache pain and 84% were nausea free at two hours (29% and 63%, respectively, with placebo). The incidence of triptan-associated adverse events known as “atypical sensations” and “pain and other pressure sensations” was 2% each in Zecuity-treated patients. The most common (greater than 5%) side effects of Zecuity were application site pain,
