Nasal administration of sumatriptan powder (AVP-825) in patients with migraine results in quicker reductions in pain intensity and migraine-related disability compared with oral sumatriptan, according to a study published in Headache.

Researchers analyzed patient data from the COMPASS study on patients with migraine (n=259). In this study, subjects were given either AVP-825 with placebo tablets or placebo plus 100 mg oral sumatriptan tablets within 1 hour of migraine onset. Following the first 12-week treatment period, participants switched treatment sequences and resumed therapy for an additional 12 weeks.

The patient sample was comprised of primarily women (84.6%) with a mean age of 40. In all patients in this cohort, the investigators observed significant differences in migraine pain intensity as well as migraine-related disability. When treated with AVP-825, patients had faster migraine pain reduction over the first 30 minutes and faster reduction in migraine-related disability over the first 45 minutes when compared with oral sumatriptan.

An odds ratio (OR) of less than 1 indicated reduced pain/migraine-related disability in the AVP-825 treatment group. The model-based odds ratios (ORs) varied from 0.38 to 0.76 for pain and 0.37 to 0.65 for disability when comparing AVP-825 to oral sumatriptan. In addition, fixed effects results demonstrated treatment-by-time interactions, indicating that pain reduction over time differed in patients treated with AVP-825 vs oral sumatriptan (P <.0001).

Since the COMPASS study did not compare the treatment group with a placebo-only arm, the investigators believe their findings may be limited. According to the researchers, administration of a placebo “might attenuate participation even in the arms where active treatment is offered.”
