Efficacy and safety of DFN-11 (sumatriptan injection, 3 mg) in adults with episodic migraine: a multicenter, randomized, double-blind, placebo-controlled study.

ABSTRACT: BACKGROUND:In a previous randomized, double-blind, proof-of-concept study in rapidly escalating migraine, a 3 mg dose of subcutaneous sumatriptan (DFN-11) was associated with fewer and shorter triptan sensations than a 6 mg dose. The primary objective of the study was to assess the efficacy and safety of acute treatment with DFN-11 compared with placebo in episodic migraine. METHODS:This was a multicenter, randomized, double-blind, placebo-controlled efficacy and safety study of DFN-11 in the acute treatment of adults with episodic migraine (study RESTOR). The primary endpoint was the proportion of subjects taking DFN-11 who were pain free at 2 h postdose in the double-blind period compared with placebo. Secondary endpoints included earlier postdose timepoints, assessments of pain relief and subjects' freedom from their most bothersome symptom (MBS) (among nausea, photophobia, and phonophobia). Safety and tolerability were assessed. RESULTS:A total of 392 subjects was screened, 268 (68.4%) were randomized, and 234 (87.3% of those randomized) completed the double-blind treatment period. The proportion of subjects who were pain free at 2 h postdose was significantly greater in the DFN-11 group than in the placebo group (51.0% vs 30.8%, P??=??0.0023). Compared with placebo, significantly higher proportions of subjects treated with DFN-11 were also pain free at 30, 60, and 90 min postdose (P?????0.0195). DFN-11 was significantly superior to placebo for pain relief at 60 min, 90 min, and 2 h postdose (P???0.0179). At 2 h postdose, DFN-11 was also significantly superior to placebo for freedom from photophobia (P??=??0.0056) and phonophobia (P??=??0.0167). Overall, 33.3% (37/111) who received DFN-11 and 13.4% (16/119) who received placebo experienced at least 1 treatment-emergent adverse event (TEAE), the most common of which were injection site swelling (7.2% vs 0.8%) and pain (7.2% vs 5.9%). Chest discomfort was about half as common in the DFN-11 treatment group as it was in the placebo group (0.9% vs 1.7%). CONCLUSIONS:This study met its primary endpoint, pain freedom at 2 h postdose, with DFN-11 significantly better than placebo, and the incidence of TEAEs and triptan sensations with DFN-11 was low. The 3 mg dose of sumatriptan in DFN-11 appears to be an effective alternative to a 6 mg SC dose of sumatriptan, with good safety and tolerability.

Project description:A 6-mg dose of SC sumatriptan is the most efficacious and fast-acting acute treatment for migraine, but a 3-mg dose of SC sumatriptan may improve tolerability while maintaining efficacy.This randomized, double-blind, crossover study compared the efficacy and tolerability of 3 mg subcutaneous (SC) sumatriptan (DFN-11) with 6 mg SC sumatriptan in 20 adults with rapidly-escalating migraine attacks. Eligible subjects were randomized (1:1) to treat 1 attack with DFN-11 and matching placebo autoinjector consecutively or 2 DFN-11 autoinjectors consecutively and a second attack similarly but with the alternative dose (3 mg or 6 mg).The proportions of subjects who were pain-free at 60 min postdose, the primary endpoint, were similar following treatment with 3 mg SC sumatriptan and 6 mg SC sumatriptan (50% vs 52.6%, P??=??.87). The proportions of subjects experiencing pain relief (P?????.48); reductions in migraine pain intensity (P?????.78); and relief from nausea, photophobia, or phonophobia (P?????.88) with 3 mg SC sumatriptan and 6 mg SC sumatriptan were similar, as were the mean scores for satisfaction with treatment (M??=??2.6 vs M??=??2.4, P??=??.81) and the mean number of rescue medications used (M??=??.11 vs M??=??.26, P??=??.32). The most common adverse events with the 3- and 6-mg doses were triptan sensations - paresthesia, neck pain, flushing, and involuntary muscle contractions of the neck - and the incidence of adverse events with both doses was similar (32 events total: 3 mg, n??=??14 [44%]; 6 mg, n??=??18 [56%], P??=??.60). Triptan sensations affected 4 subjects with the 6-mg dose only, 1 subject with the 3-mg dose only, and 7 subjects with both sumatriptan doses. Chest pain affected 2 subjects (10%) treated with the 6-mg dose and no subjects (0%) treated with the 3-mg dose of DFN-11. There were no serious adverse events.The 3-mg SC dose of sumatriptan in DFN-11 provided relief of migraine pain and associated symptoms comparable to a 6-mg SC dose of sumatriptan. Tolerability was similar with both study medications; DFN-11 treatment was associated with fewer triptan sensations than the 6-mg dose. DFN-11, with its 3-mg dose of sumatriptan, may be a clinically useful alternative to higher-dose autoinjectors.

Project description:BACKGROUND:DFN-11, a 3 mg sumatriptan subcutaneous (SC) autoinjector for acute treatment of migraine, has not been assessed previously in multiple attacks. The objective of this study was to evaluate the efficacy, tolerability, and safety of DFN-11 in the acute treatment of multiple migraine attacks. METHODS:This was an 8-week open-label extension of multicenter, randomized, double-blind, placebo-controlled US study. Subjects averaging 2 to 6 episodic migraine attacks per month were randomized to DFN-11 or placebo to treat a single attack of moderate-to-severe intensity and then entered the extension study to assess the efficacy, tolerability, and safety of DFN-11 in multiple attacks of any pain intensity. RESULTS:Overall, 234 subjects enrolled in the open-label period, and 29 (12.4%) discontinued early. A total of 848 migraine episodes were treated with 1042 doses of open-label DFN-11 and subjects treated a mean (SD) of 3.9 (2.3) attacks. At 2 h postdose in attacks 1 (N?=?216), 2 (N?=?186), 3 (N?=?142) and 4 (N?=?110), respectively, pain freedom rates were 57.6%, 64.6%, 61.6%, and 66.3%; pain relief rates were 83.4%, 88.4%, 84.1%, and 81.7%; most bothersome symptom (MBS)-free rates were 69.0%, 76.5%, 77.7%, and 74.7%; nausea-free rates were 78.1%, 84.6%, 86.5%, and 85.7%; photophobia-free rates were 75.3%, 76.4%, 72.3%, and 77.5%; and phonophobia-free rates were 75.2%, 77.5%, 73.6%, and 76.0%. Overall, 40.6% (89/219) of subjects reported treatment-emergent adverse events (TEAE), the most common of which were associated with the injection site: swelling (12.8%), pain (11.4%), irritation (6.4%), and bruising (6.4%). Most subjects (65.2%, 58/89) had mild TEAEs; severe TEAEs were reported by 1 subject (treatment-related jaw tightness). Five subjects (2.1%) discontinued due to adverse events, which included mild throat tightness (n?=?2), moderate hernia pain (n?=?1), moderate hypersensitivity (n?=?1), and 1 subject with mild nausea and moderate injection site swelling. There were no serious TEAEs and no new or unexpected safety findings. CONCLUSION:DFN-11 was effective, tolerable, and safe in the acute treatment of 4 migraine attacks over 8 weeks, with consistent responses on pain and associated symptoms. Most TEAEs were mild, with a very low incidence of triptan-related TEAEs. DFN-11 is potentially an effective and safe alternative for the acute treatment of migraine.

Project description:BackgroundDFN-02 is a novel intranasal spray formulation composed of sumatriptan 10 mg and a permeation-enhancing excipient comprised of 0.2% 1-O-n-Dodecyl-β-D-Maltopyranoside (DDM). This composition of DFN-02 allows sumatriptan to be rapidly absorbed into the systemic circulation and exhibit pharmacokinetics comparable to subcutaneously administered sumatriptan. Rapid rate of absorption is suggested to be important for optimal efficacy. The objective of this study was to evaluate the safety and tolerability of DFN-02 (10 mg) in the acute treatment of episodic migraine with and without aura over a 6-month period based on the incidence of treatment-emergent adverse events and the evaluation of results of clinical laboratory tests, vital signs, physical examination, and electrocardiograms.MethodsThis was a multi-center, open-label, repeat-dose safety study in adults with episodic migraine with and without aura. Subjects diagnosed with migraine with or without aura according to the criteria set forth in the International Classification of Headache Disorders, 2nd edition, who experienced 2 to 6 attacks per month with fewer than 15 headache days per month and at least 48 headache-free hours between attacks, used DFN-02 to treat their migraine attacks acutely over the course of 6 months.ResultsA total of 173 subjects was enrolled, 167 (96.5%) subjects used at least 1 dose of study medication and were evaluable for safety, and 134 (77.5%) subjects completed the 6-month study. A total of 2211 migraine attacks was reported, and 3292 doses of DFN-02 were administered; mean per subject monthly use of DFN-02 was 3.6 doses. Adverse events were those expected for triptans, as well as for nasally administered compounds. No new safety signals emerged. Dysgeusia and application site pain were the most commonly reported treatment-emergent adverse events over 6 months (21% and 30.5%, respectively). Most of the treatment-emergent adverse events were mild. There were 5 serious adverse events, all considered unrelated to the study medication; the early discontinuation rate was 22.5% over the 6-month treatment period.ConclusionDFN-02 was shown to be well tolerated when used over 6 months to treat episodic migraine acutely.

Project description:ObjectiveThe objective of this study was to evaluate the efficacy, tolerability, and safety of 120 mg DFN-15 vs placebo for the acute treatment of migraine.BackgroundCertain nonsteroidal anti-inflammatory drugs (NSAIDs) are guideline-recommended therapies for the acute treatment of migraine, but patients who use them may have issues with gastrointestinal tolerability. Celecoxib, a selective inhibitor of cyclooxygenase-2, produces analgesia similar to nonselective NSAIDs. DFN-15 is an oral, ready-made liquid solution of celecoxib being investigated for the acute treatment of migraine.MethodsA randomized, double-blind, placebo-controlled, efficacy, tolerability, and safety study in adults with migraine was conducted. Subjects treated a single migraine attack with 120 mg DFN-15 or placebo as soon as possible after the onset of pain of moderate to severe intensity. The 2 independent coprimary efficacy endpoints were the proportion of subjects with freedom from pain and the absence of the most bothersome symptom (MBS) at 2 hours postdose. A second double-blind treatment period followed the first, but did not contribute to the primary outcomes and will be reported elsewhere.ResultsThere were 622 subjects randomized (1:1) to double-blind treatment with either 120 mg DFN-15 or placebo, and 567 (91.2%) treated a migraine with study drug (n = 285 DFN-15; n = 282 placebo). Groups were balanced in demographic characteristics; the mean age was 40, and most subjects were female (87% [494/567]). At 2 hours postdose, DFN-15 was significantly superior to placebo for pain freedom (35.6% [98/275] vs 21.7% [57/263], P < .001), with an odds ratio (95% CI) of 2.00 (1.36, 2.94) and for freedom from the MBS (57.8% [134/232] vs 44.8% [104/232], P = .007), with an odds ratio (95% CI) of 1.68 (1.17, 2.43). A total of 13.3% (38/285) of DFN-15-treated subjects and 8.9% (25/282) of placebo-treated subjects reported a treatment-emergent adverse event (TEAE). Study drug-related TEAEs were reported by 9.1% (26/285) of DFN-15 subjects and 6.0% (17/282) of placebo subjects, the most common of which were dysgeusia (4.2% [12/285] vs 1.4% [4/282]) and nausea (3.2% [9/285] vs 1.8% [5/282]). No subjects treated with DFN-15 reported TEAEs that were severe or led to withdrawal, and no serious TEAEs or deaths were reported in the study.ConclusionsDFN-15 was significantly more effective than placebo for the acute treatment of migraine, with a generally favorable tolerability and safety profile.

Project description:BackgroundThe commercial formulation of sumatriptan nasal spray is an effective option for migraine patients requiring or preferring a non-oral route of drug administration, but its utility is limited by poor absorption and tolerability issues. DFN-02, a new formulation of sumatriptan 10 mg nasal spray, is co-formulated with a permeation enhancer that gives it pharmacokinetics comparable to subcutaneous sumatriptan. As reported previously, DFN-02 was significantly better than placebo on multiple efficacy endpoints at 2 h postdose, including pain freedom, absence of the most bothersome symptom, and pain relief, and its safety and tolerability profiles were excellent.ObjectiveThe objective of this study was to assess the efficacy of acute treatment of migraine with DFN-02, including its effect on migraine-related functional disability and patient satisfaction with treatment.MethodsThis was a multicenter, randomized, double-blind, placebo-controlled efficacy and safety study of DFN-02 in adults with episodic migraine. Functional disability and subject satisfaction with treatment were prespecified endpoints, assessed in real-time by subjects, using an electronic diary.ResultsIn total, 107 subjects were randomized. DFN-02 was significantly superior to placebo for the reduction in functional disability score from predose level at 2 h after treatment (- 1.2 vs. - 0.6, p < 0.001). Subjects treated with DFN-02 were also more likely to be satisfied or very satisfied than subjects treated with placebo at 2 h postdose (70.0% vs. 44.2%, p = 0.027). Using the Patient Perception of Migraine Questionnaire-Revised at 24 h postdose, DFN-02 mean scores were significantly superior to placebo for the subscales of efficacy (65.2 vs. 42.5, p = 0.016) and function (68.9 vs. 42.1, p = 0.001), and for total score (71.0 vs. 56.6, p = 0.016); global medication effectiveness (p = 0.027); and overall satisfaction (p = 0.019). Placebo was significantly better than DFN-02 on the tolerability subscale (94.8 vs. 88.5, p = 0.026). At 24 h postdose, subjects reported significantly higher satisfaction with DFN-02 compared with satisfaction reported pre-randomization regarding their usual migraine medication (p = 0.012).ConclusionDFN-02 was superior to placebo for the relief of migraine-related functional disability, and provided greater satisfaction than placebo or subjects' usual acute treatment.Trial registrationClinicalTrials.gov identifier: NCT02856802.

Project description:ObjectiveTo evaluate the efficacy and safety of two dosing regimens of fremanezumab in Japanese and Korean patients with episodic migraine.BackgroundEpisodic migraine, which accounts for more than 90% of migraine cases, is inadequately addressed by widely available preventive therapies. Fremanezumab, a monoclonal antibody that selectively targets the trigeminal sensory neuropeptide calcitonin gene-related peptide involved in migraine pathogenesis, has demonstrated efficacy in international Phase 3 trials of patients with both chronic and episodic migraine.MethodsThis Phase 3 randomized, placebo-controlled trial randomly assigned patients with episodic migraine to receive subcutaneous fremanezumab monthly (225 mg at baseline, week 4, and week 8), fremanezumab quarterly (675 mg at baseline and placebo at weeks 4 and 8), or matching placebo. The primary endpoint was the mean change from baseline in the monthly average number of migraine days during the 12-week treatment period after the first dose.ResultsOf 357 patients enrolled (safety set, n = 356; full analysis set, n = 354), the least-squares mean (±standard error) reductions in the average number of migraine days per month during 12 weeks were significantly greater with fremanezumab monthly (-4.0 ± 0.4, n = 121) and fremanezumab quarterly (-4.0 ± 0.4, n = 117) than with placebo (-1.0 ± 0.4, n = 116; p < 0.0001 for both comparisons). The proportion of patients reaching at least a 50% reduction in the monthly average number of migraine days during the 12-week period after initial administration was also significantly improved with fremanezumab (fremanezumab monthly, 41.3%; fremanezumab quarterly, 45.3%; placebo, 11.2%; p < 0.0001 for both comparisons) as were other secondary endpoints (p < 0.001 for all comparisons between fremanezumab and placebo). Injection-site reactions were more common in fremanezumab-treated patients (fremanezumab monthly, 25.6%; fremanezumab quarterly, 29.7%; placebo, 21.4%).ConclusionFremanezumab prevents episodic migraine in Japanese and Korean patients to a similar extent than in previously reported populations with no new safety concerns.
