Subcutaneous sumatriptan delivery devices: comparative ease of use and preference among migraineurs.

Andre Anthony D AD, Brand-Schieber Elimor E, Ramirez Margarita M, Munjal Sagar S et al.

Several sumatriptan subcutaneous autoinjector devices for acute treatment of migraine patients are available, each device differs with respect to design and features. Determining device preference and ease of use is important because patients experiencing a migraine attack are often functionally impaired. The objective of this human factors study was to compare migraine patients' device use performance and preferences for three sumatriptan subcutaneous autoinjectors: a disposable two-step device (Zembrace® SymTouch®), a disposable three-step device (Sumavel® DosePro®), and a multistep reloadable device (Imitrex® STATdose®), using simulated injections. Each study subject performed two unaided simulated injections with each of three different drug delivery devices, which were presented in counterbalanced order. The participants were then asked to rate the three devices on various subjective measures. The primary end point was overall device preference using a visual analog scale. A total of 54 subjects participated and each subject performed two simulated injections with each of the three devices. Most subjects preferred the two-step device (88.9%) to the three-step (13.0%) and the reloadable (1.9%). The two-step device had higher mean overall preference ratings (F (2, 159)=56.6, P<0.01) and higher ratings for ease of use, intuitiveness, convenience, portability, and control. The two-step device had a first injection full-dose delivery success rate of 44.4%, higher than both the reloadable (24.1%) and the three-step (3.7%) devices. The number of errors with the two-step device (n=3) was ~90% lower than the three-step (n=49) and reloadable (n=44) devices. In this human factors study, 54 migraineurs used simulated injections to compare three sumatriptan subcutaneous delivery devices. Zembrace SymTouch, a two-step device, was most preferred compared with Sumavel DosePro and Imitrex STATdose. It also ranked highest for ease of use and various other measures. In this study, migraine patients preferred the autoinjector that they rated as simpler and more intuitive.

A review of needle-free sumatriptan injection for rapid control of migraine.

Rothrock John F JF, Freitag Frederick G FG, Farr Stephen J SJ, Smith Edward F EF

The treatment of migraine was transformed in 1992 with the introduction of the first triptan-based therapy, subcutaneous (SC) sumatriptan. SC sumatriptan has high efficacy and a rapid onset of action compared with other available triptans and formulations presumably because of its short Tmax, high Cmax, and avoidance of enteral absorption. Because of these characteristics, SC sumatriptan is still considered the most reliably and rapidly effective self-administered medication available for acute migraine. Even so, it is relatively little used possibly in part because of patient "needle-phobia." The needle-free sumatriptan injection system (Sumavel DosePro) was developed to address this concern. Clinical trials have shown that the needle-free system is bioequivalent to needle-based injection systems, easy to use, and capable of providing rapid and effective symptom relief for many migraine episodes. Sumavel DosePro is an effective treatment for migraine and should be part of the therapeutic armamentarium, particularly in cases where a rapid onset of action is critical or where oral administration is problematic.

Needle-free subcutaneous sumatriptan for triptan users requiring a change in migraine therapy: efficacy and impact on patient-rated functionality, satisfaction, and confidence.

Rothrock John F JF, Cady Roger K RK, Aurora Sheena K SK, Brandes Jan Lewis JL et al.

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. 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). NCT01016834 on clinicaltrials.gov. 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. With SDP, triptan users requiring a change in therapy experienced increased efficacy, satisfaction with therapy, and confidence in treatment without deterioration in tolerability.

Satisfaction with and confidence in needle-free subcutaneous sumatriptan in patients currently treated with triptans.

Cady Roger K RK, Aurora Sheena K SK, Brandes Jan L JL, Rothrock John F JF et al.

To evaluate patient satisfaction with and confidence in Sumavel® DosePro® (needle-free subcutaneous sumatriptan) among current triptan users administering Sumavel DosePro for up to 4 migraine attacks. Sumavel DosePro is a needle-free, single-use device that facilitates subcutaneous injection of sumatriptan 6 mg and confers relief as early as 10 minutes after dosing. In this open-label, multicenter study, Sumavel DosePro was self-administered for ≤4 migraine attacks (over a ≤60-day period) involving moderate or severe baseline pain by adult migraineurs who currently were using triptans (any form, any dosage) and reported being less than very satisfied with their current therapy (i.e., baseline satisfaction ranging from satisfied to very dissatisfied). Treatment satisfaction was measured via the Patient Perception of Migraine Questionnaire, revised (PPMQ-R). Among the 212 patients using Sumavel DosePro to treat ≥1 migraine attack, PPMQ-R Overall Satisfaction (primary endpoint) increased significantly from baseline to the end of treatment (mean ± SD 65.7 ± 19.8 vs. 73.7 ± 29.1, P = .0007), an improvement that met the criterion for clinical significance. From baseline to the end of treatment, PPMQ-R scores also improved significantly for Efficacy (62.2 ± 17.6 vs. 76.2 ± 23.7, P < .0001), Functionality (59.0 ± 22.3 vs. 73.8 ± 25.3, P < .0001), and Tolerability (83.9 ± 13.1 vs. 86.4 ± 15.0, P = .02), but declined for Ease of Use (82.6 ± 15.3 vs 67.8 ± 27.6, P < .0001). For all global satisfaction domains, the percentage of patients satisfied or very satisfied increased from baseline to the end of treatment (Overall Satisfaction 36.3% vs. 64.0%, Satisfaction with Medication Effectiveness 40.1% vs. 68.2%, Satisfaction with Side Effects 48.6% vs. 67.3%). The percentage of patients who were confident or very confident in treating repeated migraine attacks also increased (baseline: 41.0%, 90% confidence interval [CI] 35.4, 46.9 vs. end of treatment: 66.5%, 90% CI 58.9, 70.1). The efficacy results (pain relief, pain-free response, sustained 24-hour pain relief and pain-free response) were consistent with those previously observed with needle-based sumatriptan. Patients currently treated with triptans and less than very satisfied with their acute migraine therapy experienced a statistically significant and clinically relevant increase in satisfaction with therapy and enhanced confidence in treatment after use of Sumavel DosePro for up to 4 migraine attacks.

Sumatriptan needle-free subcutaneous (Sumavel(®) DosePro™) approved for the acute treatment of migraine, with or without aura, and cluster headaches.

Freitag Frederick G FG

Sumatriptan subcutaneous administration is the fastest and most effective of the triptans for relief of acute migraine headache. This occurs even when the patient has already developed symptoms related to central sensitization, a key parameter in determining the effectiveness of these agents. In patients whose migraine attacks have historically failed to respond to oral triptans, this route of administration has also proven to be more consistent and effective. Until recently this method of drug delivery was dependent upon a needle for administration. A new method of delivery for this agent, Sumavel(®) DosePro™, eliminates the needle and disposal issues coupled with an improved ease of use of drug delivery and acceptable tolerability for patients in clinical trials.

Needle-free subcutaneous sumatriptan (Sumavel DosePro): bioequivalence and ease of use.

Brandes Jan Lewis JL, Cady Roger K RK, Freitag Fred G FG, Smith Timothy R TR et al.

Subcutaneous (s.c.) injection of sumatriptan is currently associated with needle aversion in some patients, and sharps disposal issues. To investigate whether a needle-free system can deliver s.c. sumatriptan. If so, to examine whether needle-free administration is bioequivalent to a 26-gauge needle-based auto-injector. Lastly, to assess the needle-free system for clinical acceptability and ease of use during migraine attacks. Two clinical trials. Study A: Pharmacokinetics and bioequivalence was studied in normal adult volunteers (n = 57 total), directly comparing needle-free (Sumavel DosePro) with needle-based (Imitrex STATdose System) administration of 6 mg s.c. sumatriptan. An incomplete, randomized, partial factorial, crossover design was used. Each subject received 2 administrations of each product, at 2 of the 3 anatomical sites (abdomen, thigh or arm). There were appropriate "washout" periods between each. Pharmacokinetic sampling was at standard time points, and tests for bioequivalence then followed. Study B: The term "ease of use" was used for clinical acceptability and utility of the needle-free system when it was assessed among 52 outpatients treating migraine attacks. Instructional materials were used as would be provided after ordinary prescription. The primary endpoint was successful use of the needle-free system to administer sumatriptan at the first attempt, including appropriate injection site selection. Second and subsequent uses of the needle-free system were also documented. For administration sites in the thigh and the abdomen, but not the arm, the needle-free and needle-based systems were bioequivalent (for all pharmacokinetic endpoints the mean ratios between the 2 devices were always between 90.1% and 115%). Among outpatients treating a migraine attack with the needle-free system, 51 of 52 on first attempt used the needle-free system successfully when treating a migraine attack. Sumavel DosePro needle-free delivery system is a new presentation of s.c. sumatriptan that delivers drug effectively, is bioequivalent to the existing needle auto-injector when used at the thigh or abdomen, and is easy to use.
