Relief of menstrual symptoms and migraine with a single-tablet formulation of sumatriptan and naproxen sodium.

BACKGROUND: Dysmenorrhea and menstrual migraine may share a common pathogenic pathway. Both appear to be mediated, in part, by an excess of prostaglandin production that occurs during menstruation. METHODS: Data were pooled from two replicate randomized controlled trials of 621 adult menstrual migraineurs with dysmenorrhea who treated migraine with sumatriptan-naproxen or placebo. Along with headache symptoms, nonpain menstrual symptoms (bloating, fatigue, and irritability) and menstrual pain symptoms (abdominal and back pain) were recorded at the time periods of 30 minutes and 1, 2, 4, and 4-24 hours. Relief of menstrual symptoms was compared using a Cochran-Mantel-Haenszel test. Logistic regression was used to determine the odds of a headache response with increasing numbers of moderate to severe dymenorrheic symptoms. RESULTS: Sumatriptan-naproxen was superior to placebo for relief of tiredness, irritability, and abdominal pain at the time periods of 2, 4, and 4-24 hours (p≤0.023); back pain at the time periods of 4 and 4-24 hours (p≤0.023); and bloating at 4-24 hours endpoint (p=0.01). The odds ratios (ORs) of attaining migraine pain freedom for 2 hours and for sustained 2-24 hours decreased as moderate to severe dysmenorrhea symptoms increased with sumatriptan-naproxen versus placebo. CONCLUSIONS: Treatment with sumatriptan-naproxen may provide relief of menstrual symptoms and migraine in female migraineurs with dysmenorrhea. The presence of moderate to severe dysmenorrhea symptoms is associated with decreased response rates for menstrual migraine, suggesting that the co-occurrence of these disorders may negatively impact the results of migraine-abortive therapy.

Sumatriptan/naproxen sodium for the acute treatment of probable migraine without aura: a randomized study.

OBJECTIVE: Probable migraine is a common, disabling migraine subtype fulfilling all but one of the diagnostic criteria for migraine. This study was conducted to evaluate the efficacy and tolerability of sumatriptan/naproxen sodium for the acute treatment of probable migraine without aura. METHODS: Patients treated a headache of probable migraine without aura when pain was moderate or severe with sumatriptan/naproxen sodium ( N = 222 intent-to-treat (ITT)) or placebo ( N = 221 ITT/complete case analysis (a) ) in this randomized, double-blind, parallel-group study. RESULTS: Sumatriptan/naproxen sodium was more effective than placebo with respect to the co-primary efficacy endpoints two-hour pain-free response (29% sumatriptan/naproxen sodium vs 11% placebo, P < 0.001) and two- to 24-hour sustained pain-free response (24% sumatriptan/naproxen sodium vs 9% placebo, P < 0.001). Sumatriptan/naproxen sodium was significantly more effective than placebo with respect to the secondary efficacy endpoints of pain-free response four hours postdose ( P < 0.001), pain-free response maintained one to two hours postdose ( P = 0.034) and two to four hours postdose ( P < 0.001), headache relief four hours postdose ( P < 0.001), headache relief maintained two to four hours postdose ( P = 0.015), sustained headache relief two through 24 hours postdose ( P = 0.002), and rescue medication use ( P < 0.001); but not productivity scores. The most common adverse events were dizziness (4% sumatriptan/naproxen sodium,<1% placebo), dry mouth (2% sumatriptan/naproxen sodium, <1% placebo), and nausea (2% sumatriptan/naproxen sodium, <1% placebo). CONCLUSION: Sumatriptan/naproxen sodium is effective in the acute treatment of probable migraine as demonstrated by higher rates of freedom from pain and restoration of function.

Pharmacokinetics and tolerability of sumatriptan after single-dose administration of a fixed-dose combination tablet of sumatriptan/naproxen sodium 85/500 mg followed two hours later by subcutaneous sumatriptan 4- or 6-mg injection: a randomized, open-label, three-period crossover study in healthy volunteers.

BACKGROUND: Rescue medication options that are consistent with the product labeling for sumatriptan/naproxen sodium (S/N) and that have been permitted in >or=1 clinical trial include the use of a second tablet of S/N, sumatriptan tablets (to a total daily dose of 200 mg), and naproxen sodium tablets (within the maximum limits recommended in the labeling). Sumatriptan subcutaneous (SC) injection might be especially useful as rescue medication mostly because of its rapid onset of activity. OBJECTIVE: The aim of this study was to assess the pharmacokinetics and tolerability of sumatriptan SC used as rescue medication after the administration of oral S/N for the treatment of migraine. METHODS: This randomized, open-label, 3-period crossover study compared the exposure to sumatriptan (Cmax and AUC to 14 hours after the administration of the second dose [AUC(0-14)]) between 3 treatment regimens: an initial dose of S/N 85/500 mg followed 2 hours later by sumatriptan 4 or 6 mg SC (S/N + S4 and S/N + S6, respectively) (test), or sumatriptan 100 mg PO (2 tablets administered 2 hours apart) (S100 + S100) (reference). Healthy adults aged 18 to 55 years were randomly assigned to receive all 3 regimens in a randomized sequence. On day 1 of each treatment period, continuous cardiovascular monitoring (ECG telemetry), serial 12-lead ECG, and serial blood pressure (BP) measurements were conducted 1 hour before to 10 hours after the administration of the first dose. Blood samples for pharmacokinetic assessment were collected up to 14 hours after the administration of the first dose. Adverse events (AEs) were monitored from the time of consent until study completion. Participants returned to the clinic for pharmacokinetic blood sampling (for S/N + S4 and S/N + S6) and for tolerability assessment at 24, 48, and 72 hours after S/N administration. RESULTS: A total of 30 healthy adults were randomized. Five withdrew prematurely (3, withdrawn consent; 1, AE; and 1, protocol deviation). Half of the subjects were men, the mean age was 27.8 years, and the mean weight was 79.3 kg (range, 54.6-100.8 kg). With S/N + S4, sumatriptan Cmax and AUC(0-14) did not exceed those with S100 + S100. Sumatriptan Cmax was 1.26-fold higher with S/N + S6 than with S100 + S100. Sumatriptan AUC(0-14) with S/N + S6 was not significantly greater than that with S100 + S100. Differences in serial BP measurements between the SC and S100 + S100 regimens were not statistically significant. The numbers of subjects in whom any AE was reported were 10 (37%) with S/N + S4, 14 (54%) with S/N + S6, and 13 (48%) with S100 + S100. CONCLUSIONS: Sumatriptan 4 and 6 mg SC administered 2 hours after an S/N tablet yielded sumatriptan exposure that did not exceed that of S100 + S100. Cmax with the S/N + S6 regimen was 1.26-fold higher than reference values. Both regimens were reasonably well tolerated. Randomized controlled trials are needed to test the efficacy and tolerability of these SC regimens. ClinicalTrials.gov identifier: NCT00875784.

Distinct pharmacokinetic profile and safety of a fixed-dose tablet of sumatriptan and naproxen sodium for the acute treatment of migraine.

OBJECTIVE: To describe the pharmacokinetic and safety profiles of sumatriptan 85 mg formulated with RT Technology (RT) and naproxen sodium 500 mg in a fixed-dose combination tablet (sumatriptan/naproxen sodium) that targets both serotonergic dysmodulation and inflammation in migraine. METHODS: Six open-label, crossover studies were conducted in healthy volunteers (Studies 1, 2, 3, 4, 5) or patients with migraine (Study 6). RESULTS: Consistently across studies, naproxen administered as a component of sumatriptan/naproxen sodium demonstrated a delayed-release profile similar to that of an enteric-coated product. Naproxen from the combination tablet showed a delayed time to peak plasma concentration and lower peak plasma concentration while exposures (area under the plasma concentration-time curve) were similar. The peak plasma concentration for naproxen was approximately 36% lower and the time to peak plasma concentration approximately 4 hours later when naproxen was administered as sumatriptan/naproxen sodium compared with a single naproxen sodium 550 mg tablet. Sumatriptan peak plasma concentration and area under the plasma concentration-time curve after administration of sumatriptan/naproxen sodium (containing sumatriptan 85 mg) were comparable to those after administration of a commercially available sumatriptan 100 mg (RT) tablet. Sumatriptan time to peak plasma concentration occurred, on average, 30 minutes earlier with sumatriptan/naproxen sodium compared with sumatriptan 100 mg (RT). No clinically significant differences between sumatriptan/naproxen sodium and sumatriptan tablets 100 mg (RT) were identified with respect to electrocardiograms, blood pressure, or heart rate. In addition, food had no significant effect on the bioavailability of naproxen or sumatriptan after administration of sumatriptan/naproxen sodium but slightly delayed the time to peak plasma concentration of sumatriptan by approximately 40 minutes. The pharmacokinetics of sumatriptan and naproxen did not differ according to whether sumatriptan/naproxen sodium was administered during a migraine attack or a migraine-free period. The pharmacokinetics of 2 sumatriptan/naproxen sodium tablets administered 2 hours apart were consistent with the pharmacokinetic predictions from a single dose of the combination tablet. The adverse-event profile of the sumatriptan/naproxen sodium combination tablet did not appear to differ from that of the individual components of the same or similar dosage strengths administered alone or in combination. In addition, the incidence of adverse events with 2 sumatriptan/naproxen sodium tablets administered 2 hours apart was lower than that with the single dose. CONCLUSION: The combination tablet of sumatriptan/naproxen sodium has unique pharmacokinetic properties. The rapid absorption of sumatriptan with the delayed-release properties of naproxen sodium from sumatriptan/naproxen sodium might contribute to its therapeutic advantage over monotherapy with either component. No clinically meaningful effects of food, administration during a migraine attack, or administration of a second tablet (2 hours after initial dose) on the pharmacokinetics or safety of sumatriptan/naproxen sodium were observed.

Combination treatment for menstrual migraine and dysmenorrhea using sumatriptan-naproxen: two randomized controlled trials.

OBJECTIVE: To evaluate the efficacy and tolerability of sumatriptan-naproxen during the mild pain phase of a single menstrual migraine attack associated with dysmenorrhea. METHODS: Two replicate randomized, multicenter, double-blind, placebo-controlled, trials of adults with menstrual migraine and dysmenorrhea were conducted. Participants treated their menstrual migraine attack during the mild pain phase (within 1 hour of onset) with sumatriptan 85 mg and naproxen sodium 500 mg in a single fixed-dose formulation (sumatriptan-naproxen) or placebo. The primary endpoint was 2-hour pain-free response. RESULTS: Sumatriptan-naproxen was statistically superior to placebo in both studies (n=311, Study 1; n=310, Study 2) for 2-hour and, 2- to 24-hour sustained pain-free response, use of headache and menstrual rescue medications, and several nonpain menstrual symptom categories. Two-hour pain-free rates were Study 1, 42% compared with 23%, and Study 2, 52% compared with 22%, P<.001. Two- to 24-hour sustained pain-free rates were Study 1, 29% compared with 18%, P=.022; Study 2, 38% compared with 10%, P<.001. Headache and menstrual medication rates were Study 1, 37% compared with 53%, P=.005; Study 2, 31% compared with 69%, P<.001. Women treated with sumatriptan-naproxen continued to be pain free through 48 hours compared with placebo: Study 1, 26% compared with 17%, P=.040; Study 2, 28% compared with 8%, P<.001. No serious adverse events were reported in either study; nausea and dizziness were the most frequently reported adverse events. CONCLUSION: Sumatriptan-naproxen provided an effective pain-free response at 2 hours, which was maintained up to 48 hours in menstrual migraineurs with dysmenorrhea. Sumatriptan-naproxen was well-tolerated and resulted in decreased rescue medication use and relief of nonpainful menstrual symptoms.

Fixed-dose sumatriptan and naproxen in poor responders to triptans with a short half-life.

OBJECTIVE: To evaluate efficacy and tolerability of a single, fixed-dose tablet of sumatriptan 85 mg/naproxen sodium 500 mg (sumatriptan/naproxen sodium) vs placebo in migraineurs who had discontinued treatment with a short-acting triptan because of poor response or intolerance. BACKGROUND: Triptan monotherapy is ineffective or poorly tolerated in 1 of 3 migraineurs and in 2 of 5 migraine attacks. In April, 2008, the Food and Drug Administration approved the combination therapy sumatriptan/naproxen sodium, developed specifically to target multiple migraine mechanisms. This combination product offers an alternative migraine therapy for patients who have reported poor response or intolerance to short-acting triptans. METHODS: Two replicate, randomized, multicenter, double-blind, placebo-controlled, 2-attack crossover trials evaluated migraineurs who had discontinued a short-acting triptan in the past year because of poor response or intolerance. Patients were instructed to treat within 1 hour and while pain was mild. RESULTS: Patients (n = 144 study 1; n = 139 study 2) had discontinued an average of 3.3 triptans before study entry. Sumatriptan/naproxen sodium was superior (P < .001) to placebo for 2- through 24-hour sustained pain-free response (primary end point) (study 1, 26% vs 8%; study 2, 31% vs 8%) and pain-free response 2 hours post dose (key secondary end point) (study 1, 40% vs 17%; study 2, 44% vs 14%). A similar pattern of results was observed for other end points that evaluated acute (2- or 4-hour), intermediate (8-hour), or 2- through 24-hour sustained response for migraine (ie, pain and associated symptoms), photophobia, phonophobia, or nausea (with the exception of nausea 2 and 4 hours post dose). The percentage of patients with at least 1 adverse event (regardless of causality) was 11% with sumatriptan/naproxen sodium compared with 4% with placebo in study 1 and 9% with sumatriptan/naproxen sodium compared with 5% with placebo in study 2. Only 1 adverse event in 1 study was reported in > or =2% of patients after treatment with sumatriptan/naproxen sodium and reported more frequently with sumatriptan/naproxen than placebo: chest discomfort was reported in 2% of subjects in study 1, and no events met this threshold in study 2. No serious adverse events attributed to study medication were reported in either study. CONCLUSION: In migraineurs who reported poor response to a short-acting triptan, sumatriptan/naproxen sodium was generally well tolerated and significantly more effective than placebo in conferring initial, intermediate, and sustained efficacy for pain and migraine-associated symptoms of photophobia and phonophobia.

Fixed-dose Sumatriptan/Naproxen Sodium Compared with each Monotherapy Utilizing the Novel Composite Endpoint of Sustained Pain-free/no Adverse Events.

A novel composite endpoint, sustained pain-free/no adverse events, was recently proposed as a more rigorous means of capturing in a single measure the attributes of migraine pharmacotherapy that patients consider most important: rapid and sustained pain-free response with no side-effects. Using pooled data from two replicate randomized, double-blind, parallel-group, placebo-controlled studies, this post hoc analysis compared the fixed-dose combination tablet sumatriptan/naproxen sodium (n = 726) with sumatriptan monotherapy (n = 723), naproxen sodium monotherapy (n = 720), and placebo (n = 742) with respect to sustained pain-free/no adverse events and closely related composite measures. Sustained pain-free/no adverse events was defined as having both a sustained pain-free response from 2 through 24 hours post-dose with no use of rescue medication and having no adverse events within up to 5 days after dosing with study medication. The percentage of patients with sustained pain-free/no adverse events was 16% with sumatriptan/naproxen sodium compared with 11%, 9% and 7% for sumatriptan, naproxen sodium and placebo, respectively (p<0.01 sumatriptan/naproxen sodium versus each other treatment). Sumatriptan/naproxen sodium was also significantly more effective than sumatriptan, naproxen sodium, and placebo for other composite endpoints including the percentages of patients with (1) sustained pain-free/no adverse events within 1 day; (2) sustained pain-free/no drug-related adverse events within up to 5 days; (3) sustained pain-free/no drug-related adverse events within 1 day; (4) sustained pain relief/no adverse events within up to 5 days; and (5) sustained pain relief/no adverse events within 1 day. The results demonstrate the superiority of sumatriptan/naproxen sodium to sumatriptan monotherapy, naproxen sodium monotherapy and placebo with respect to the rigorous and clinically relevant endpoint of sustained pain-free/no adverse events and reinforce the usefulness of utilizing this new composite endpoint.

Sumatriptan-naproxen for acute treatment of migraine: a randomized trial.

CONTEXT: Multiple pathogenic mechanisms may be involved in generating the migraine symptom complex, and multimechanism-targeted therapy may confer advantages over monotherapy. OBJECTIVE: To evaluate the efficacy and safety of a fixed-dose tablet containing sumatriptan succinate and naproxen sodium relative to efficacy and safety of each monotherapy and placebo for the acute treatment of migraine. DESIGN, SETTING, AND PARTICIPANTS: Two replicate, randomized, double-blind, single-attack, parallel-group studies conducted among 1461 (study 1) and 1495 (study 2) patients at 118 US clinical centers who were diagnosed as having migraine and received study treatment for a moderate or severe migraine attack. INTERVENTIONS: Patients were randomized in a 1:1:1:1 ratio to receive a single tablet containing sumatriptan, 85 mg, and naproxen sodium, 500 mg; sumatriptan, 85 mg (monotherapy); naproxen sodium, 500 mg (monotherapy); or placebo, to be used after onset of a migraine with moderate to severe pain. MAIN OUTCOME MEASURES: Primary outcome measures included the percentages of patients with headache relief 2 hours after dosing, absence of photophobia, absence of phonophobia, and absence of nausea for the comparison between sumatriptan-naproxen sodium and placebo, and the percentages of patients with sustained pain-free response for the comparison between sumatriptan-naproxen sodium and each monotherapy. RESULTS: Sumatriptan-naproxen sodium was more effective than placebo for headache relief at 2 hours after dosing (study 1, 65% vs 28%; P<.001 and study 2, 57% vs 29%; P<.001), absence of photophobia at 2 hours (58% vs 26%; P<.001 and 50% vs 32%; P<.001), and absence of phonophobia at 2 hours (61% vs 38%; P<.001 and 56% vs 34%; P<.001). The absence of nausea 2 hours after dosing was higher with sumatriptan-naproxen sodium than placebo in study 1 (71% vs 65%; P = .007), but in study 2 rates of absence of nausea did not differ between sumatriptan-naproxen sodium and placebo (65% vs 64%; P = .71). For 2- to 24-hour sustained pain-free response, sumatriptan-naproxen sodium was superior at P<.01 (25% and 23% in studies 1 and 2, respectively) to sumatriptan monotherapy (16% and 14% in studies 1 and 2), naproxen sodium monotherapy (10% and 10% in studies 1 and 2), and placebo (8% and 7% in studies 1 and 2). The incidence of adverse events was similar between sumatriptan-naproxen sodium and sumatriptan monotherapy. CONCLUSION: Sumatriptan, 85 mg, plus naproxen sodium, 500 mg, as a single tablet for acute treatment of migraine resulted in more favorable clinical benefits compared with either monotherapy, with an acceptable and well-tolerated adverse effect profile.

Twelve-month tolerability and safety of sumatriptan-naproxen sodium for the treatment of acute migraine.

OBJECTIVES: To evaluate the long-term safety and tolerability of sumatriptan-naproxen sodium for the treatment of moderate to severe acute migraines and to assess the safety of administration of an optional second dose. PATIENTS AND METHODS: A 12-month, multicenter, open-label safety study was conducted in adults treated for migraine attacks of moderate to severe intensity from April 14, 2004, to August 18, 2005. Safety evaluations included adverse events and laboratory tests. RESULTS: Of 600 patients enrolled, 565 (94%) were treated for at least 1 migraine. Of treated patients, 414 (73%) and 362 (64%) completed 6 and 12 months of treatment, respectively. Of the 24,485 attacks treated, 17,144 (70%) were treated with only 1 dose. On average, patients treated 5 migraine attacks per month, with a median of 6 days between attacks. The most common treatment-related adverse events were nausea, muscle tightness, and dizziness. Fourteen patients reported 1 or more serious adverse event with only 1 judged probably related to treatment. No deaths occurred. Eight percent of patients discontinued participation in the study because of adverse events or pregnancy. The rates of adverse events reported were no higher after treatment with 2 tablets (at least 2 hours apart) compared with 1 tablet. CONCLUSIONS: In this 12-month data set of more than 24,000 migraine attacks in 565 patients, sumatriptan-naproxen sodium formulated in a single tablet was well tolerated when used episodically for the treatment of acute migraine. The adverse events did not differ from those expected for the individual components alone, and no new or unexpected findings occurred.
