Abstract

OBJECTIVE:

To evaluate efficacy of, satisfaction with, and confidence in SDP (SUMAVEL DosePro *) among triptan users requiring a change in therapy. SDP is a needle-free, subcutaneous sumatriptan product that confers relief as early as 10 minutes postdose.

RESEARCH DESIGN AND METHODS:

In an open-label study, SDP was administered for ≤4 migraine attacks over ≤60 days by migraineurs currently treated with triptans (any form/dosage). In the 90 patients with baseline Migraine-ACT scores ≤2 (indicating the need for a change in therapy), efficacy data were collected from patient diaries, and satisfaction was measured with the revised Patient Perception of Migraine Questionnaire (PPMQ-R).

CLINICAL TRIAL REGISTRATION NUMBER:

NCT01016834 on clinicaltrials.gov.

RESULTS:

Across all attacks, the rates of pain relief were 30.7%, 66.4%, 80.1%, 81.6%, and 77.6% at 0.25, 0.5, 1, 2, and 24 hours postdose, respectively. Corresponding results for pain-free response were 0.7%, 14.8%, 35.0%, 48.0, and 65.7%. Sustained 24-hour pain relief was observed in 61.0% of attacks. PPMQ-R scores (transformed to 0-100 scales, mean ± SD) improved from baseline to end of treatment for Efficacy (52.5 ± 17.8 versus 74.8 ± 23.4, p < 0.0001) and Functionality (46.2 ± 22.3 versus 71.3 ± 25.2, p < 0.0001) with no deterioration in Tolerability (80.6 ± 14.7 versus 83.5 ± 17.7, p = 0.12). PPMQ-R Overall Satisfaction score increased from baseline to end of treatment (55.1 ± 23.2 versus 74.6 ± 27.7, p < 0.0001). The percentage of patients (90% confidence interval) confident or very confident in treating migraine attacks increased from 22.2% (15.2, 30.6) at baseline to 57.8% (48.6, 66.6) at end of treatment. Results should be interpreted in the context of the open-label design of the original study.

CONCLUSION:

With SDP, triptan users requiring a change in therapy experienced increased efficacy, satisfaction with therapy, and confidence in treatment without deterioration in tolerability.
