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.

Progressive supranuclear palsy: Neuropathology, clinical presentation, diagnostic challenges, management, and emerging therapies.

Progressive supranuclear palsy (PSP) is a neurodegenerative disease characterized by the accumulation of 4R-tau protein aggregates in various brain regions. PSP leads to neuronal loss, gliosis, and tau-positive inclusions, such as neurofibrillary tangles, tufted astrocytes, and coiled bodies. These pathological changes mainly affect the brainstem and the basal ganglia, resulting in distinctive MRI features, such as the hummingbird and morning glory signs. PSP shows clinical heterogeneity and presents as different phenotypes, the most classical of which is Richardson's syndrome (PSP-RS). The region of involvement and the mode of atrophy spread can further distinguish subtypes of PSP. PSP patients can experience various signs and symptoms, such as postural instability, supranuclear ophthalmoplegia, low amplitude fast finger tapping, and irregular sleep patterns. The most common symptoms of PSP are postural instability, falls, vertical gaze palsy, bradykinesia, and cognitive impairment. These features often overlap with those of Parkinson's disease (PD) and other Parkinsonian syndromes, making the diagnosis challenging. PSP is an essential clinical topic to research because it is a devastating and incurable disease. However, there are still many gaps in knowledge about its pathophysiology, diagnosis, and treatment. Several clinical trials are underway to test noveltherapies that target tau in various ways, such as modulating its post-translational modifications, stabilizing its interaction with microtubules, or enhancing its clearance by immunotherapy. These approaches may offer new hope for slowing down the progression of PSP. In this review, we aim to provide an overview of the current knowledge on PSP, from its pathogenesis to its management. We also discuss the latest advances and future directions in PSP research.

Sumatriptan-naproxen and butalbital: a double-blind, placebo-controlled crossover study.

OBJECTIVES: The primary objective was to compare the efficacy of a sumatriptan and naproxen combination medication (SumaRT/Nap-85mg sumatriptan and 500mg naproxen sodium), a butalbital-containing combination medication (BCM-50mg butalbital, 325mg acetaminophen, 40mg caffeine), and placebo when used to treat moderate to severe migraine headache pain in subjects who used BCMs in the past. BACKGROUND: Despite the lack of Food and Drug Administration approval and the absence of placebo-controlled trials to demonstrate efficacy, butalbital-containing medications are among the most commonly prescribed acute migraine treatments in the United States. Butalbital-containing medications are associated with serious and undesirable side effects, and have been linked to the chronification of migraine and development of medication-overuse headaches. This study compares the relative efficacy, safety, and tolerability of a fixed dose SumaRT/Nap versus a BCM and placebo. METHODS: Enrolled subjects were required to have treated at least 1 migraine with a butalbital medication in the past. Enrolled subjects treated 3 moderate to severe migraines using each of the 3 study treatments once in a randomized sequence. The primary endpoint compared SumaRT/Nap versus BCM for sustained pain freedom at 2-24 hours without the use of any rescue medication. This study combines data from 2 identical outpatient, randomized, multicenter, double-blind, double-dummy, 3 attack crossover studies in adult migraineurs (International Classification of Headache Disorders, 2nd edition). RESULTS: A total of 442 subjects treated at least 1 attack with study medication. The majority of the treated subjects were female (88%) with a mean age 43 years, who reported that their migraines had a severe impact on their lives (78% with Headache Impact Test-6 of >59). At screening, 88% of subjects reported current butalbital use; 68% had used butalbital for more than 6 weeks; and 82% reported satisfaction with butalbital. Across treatment groups, 28-29% of subjects took study medication within 15 minutes of migraine onset, 34-37% of subjects took study medication >15 minutes to 2 hours after onset, and 32-36% of subjects took study medication more than 2 hours after onset. This study did not detect a difference at the nominal 0.05 level in percent sustained pain-free between SumaRT/Nap (8%), BCM (6%), and placebo (3%). SumaRT/Nap was superior to BCM for pain free at 2, 4, 6, 8, 24, 48 hours (P≤.044); pain relief (mild or no pain) at 2, 4, 6, 8, 24, 48 hours (P≤.01); sustained pain relief 2-24 hours (P<.001); migraine free (pain free with no nausea, photophobia, or phonophobia) at 4, 6, 8, 24, 48 hours (P≤.046); and complete symptom free (migraine free with no neck/sinus pain) at 4, 6, 8, 48 hours (P≤.031). Adverse event incidence was similar for all treatments (10%, 12%, and 9% for placebo, SumaRT/Nap, and BCM, respectively). Nausea was the most frequent adverse event (2%, 2%, and <1% for placebo, SumaRT/Nap, and BCM, respectively). Five serious adverse events were reported by 3 subjects: viral meningitis and colon neoplasm (placebo); chest pain and hypertension 17 days postdose (SumaRT/Nap); and breast cancer (BCM). Investigators judged no serious adverse events related to study medication. CONCLUSIONS: This study primarily included subjects whose migraines significantly impacted their lives. Before the study, these subjects used butalbital-containing medications as part of their current migraine treatment regimen and were satisfied with it, suggesting they were butalbital responders who had found a workable treatment strategy for themselves. When treated with SumaRT/Nap versus BCM in this study, however, a significant proportion of subjects reported better treatment outcomes for themselves for both migraine pain and associated symptoms. Use of SumaRT/Nap was also associated with less rescue medication use and a longer time before use of rescue medication compared with both BCM and placebo.

Sumatriptan-naproxen sodium for menstrual migraine and dysmenorrhea: satisfaction, productivity, and functional disability outcomes.

OBJECTIVE: To evaluate the impact of a sumatriptan/naproxen sodium combination tablet on patient satisfaction, productivity, and functional disability in menstrual migraine treated during the mild pain phase of a single menstrual migraine attack associated with dysmenorrhea. BACKGROUND: Menstrual migraineurs with dysmenorrhea represent a unique patient population not previously studied. When health outcomes end points are analyzed alongside traditional efficacy end points in migraine studies, a more comprehensive and robust understanding of the many factors that may influence patients' choice of and adherence to pharmacological treatments for migraine is observed. METHODS: In 2 replicate, multicenter, randomized, double-blind, placebo-controlled trials, participants with menstrual migraine and dysmenorrhea treated a single menstrual migraine attack with a single fixed-dose tablet of sumatriptan 85 mg formulated with RT Technology™ and naproxen sodium 500 mg (sumatriptan-naproxen sodium) or placebo. RESULTS: Participants randomized to sumatriptan-naproxen sodium were significantly more satisfied than those randomized to placebo at 24 hours post dose, as demonstrated by higher satisfaction subscale scores for efficacy (P < .001 for both studies), functionality (P = .003 for study 1; P < .001 for study 2), and ease of use (P = .027 for study 1; P = .011 for study 2). There was little bothersomeness of side effects associated with either treatment. Use of sumatriptan-naproxen sodium was also associated with lower reported "lost-time equivalents" in work and leisure time (pooled analysis, P = .003) and lower rates of functional disability (P = .05, study 1; P < .001, study 2) compared with placebo. CONCLUSION: A fixed-dose combination tablet containing sumatriptan and naproxen sodium significantly improved patient satisfaction, productivity, and restoration of normal functioning in menstrual migraineurs with dysmenorrhea.

Long-term evaluation of sumatriptan and naproxen sodium for the acute treatment of migraine in adolescents.

OBJECTIVES: To evaluate the long-term safety, tolerability, effectiveness, impact on quality of life, and medication satisfaction of sumatriptan/naproxen sodium in the acute treatment of migraine headache in adolescents. METHODS: This 12-month, multicenter, open-label, safety study was conducted in adolescents (aged 12-17 years) with an average of 2-8 migraines/month typically lasting >2 hours untreated for >6 months prior to initiation. Subjects were instructed to treat migraines as early as possible and were allowed to rescue 2 hours post dose with a single dose of a naproxen-containing product, over-the-counter pain reliever, or anti-emetics. Subjects were advised not to take a second tablet of sumatriptan/naproxen sodium without at least a 24-hour headache-free period. Safety evaluations included adverse events, laboratory tests, and vital signs and electrocardiogram evaluation. Other evaluations included freedom from pain, quality of life, and medication satisfaction. RESULTS: Of the 656 subjects enrolled, 622 (95%) treated at least 1 migraine with sumatriptan/naproxen sodium, of which 435 (70%) and 363 (58%) completed 6 and 12 months of the study, respectively. Overall, there were 12,927 exposures to sumatriptan/naproxen sodium: on average 2.5 tablets were taken per month per subject. The most common treatment-related adverse events were nausea (7%), dizziness (3%), muscle tightness (3%), and chest discomfort (3%). There were no deaths; 4 subjects had 5 serious adverse events (suicide attempt, hemolytic anemia and syncope, suicidal ideation, spontaneous abortion) unrelated to sumatriptan/naproxen sodium and resolved without sequelae. Seven percent of subjects discontinued participation in the study because of an adverse event; 5% of subjects discontinued due to lack of efficacy. Overall, 42% of the migraine attacks were pain-free within 2 hours of treatment with sumatriptan/naproxen sodium, subjects reported improvements from baseline in 2 of 3 quality of life domains over time, and were generally satisfied with the efficacy and overall treatment at the end of the study. CONCLUSION: In adolescent migraineurs, after up to 12 months and over 12,000 exposures to sumatriptan/naproxen sodium, there were no new or clinically significant findings in the safety parameters, including the frequency and nature of adverse events, as compared to the individual components or to the adverse event profile in adults. In addition, sumatriptan/naproxen sodium provided freedom from pain over time, improvements in quality of life and medication satisfaction.

Changes in salivary prostaglandin levels during menstrual migraine with associated dysmenorrhea.

OBJECTIVE: To measure prostaglandin levels in the saliva of individuals during menstrual migraine associated with dysmenorrhea (MMaD) and in response to treatment with a single tablet combination of sumatriptan succinate and naproxen sodium. BACKGROUND: Prostaglandins are thought to play a role in MMaD as elevated serum prostaglandin levels have been reported during attacks of menstrual migraine and are increased in the menstrual fluid of women with dysmenorrhea. While triptans are the primary line of migraine treatment, nonsteriodal anti-inflammatory drugs are the most commonly prescribed therapy for dysmenorrhea symptoms. Data from recent clinical studies have provided evidence that treatment with a single tablet combination of sumatriptan and naproxen sodium is an effective abortive therapy for attacks of MMaD. METHODS: Women diagnosed with MMaD were treated with a sumatriptan succinate and naproxen sodium single tablet combination or placebo at time of migraine attack. Saliva samples were collected at time of attack as well as 2 and 4 hours after treatment. PGD(2), PGE(2), PGF(2), PGI(2), and TXA(2) levels were determined by enzyme-linked immunosorbent assay. RESULTS: Elevated levels of PGD(2), PGF(2), and TXA(2) at 2 and 4 hours and PGE(2) at 4 hours were found in saliva obtained from placebo subjects when compared with onset of attack levels. However, in subjects treated with a single tablet combination of sumatriptan and naproxen sodium, the levels of PGD(2), PGF(2), and PGE(2) were not elevated at either time point while TXA(2) levels were still elevated at 4 hours. CONCLUSIONS: Data from this pilot study provide evidence that saliva levels of several prostaglandins increase during attacks of MMaD and that treatment with a single tablet combination of sumatriptan and naproxen sodium prevents elevation of prostaglandin levels.

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.

IONIS-PKKRx a Novel Antisense Inhibitor of Prekallikrein and Bradykinin Production.

Kallikrein is the key contact system mediator responsible for the conversion of high-molecular-weight kininogen into the inflammatory vasodilator peptide bradykinin, a process regulated by C1-esterase inhibitor (C1-INH). In hereditary angioedema (HAE), genetic mutations result in deficient or dysfunctional C1-INH and dysregulation of the contact system leading to recurrent, sometimes fatal, angioedema attacks. IONIS-PKKRx is a second-generation 2'-O-(2-methoxyethyl)-modified chimeric antisense oligonucleotide, designed to bind and selectively reduce prekallikrein (PKK) mRNA in the liver. IONIS-PKKRx demonstrated dose-dependent reduction of human prekallikrein hepatic mRNA and plasma protein in transgenic mice and dose- and time-dependent reductions of plasma PKK in Cynomolgus monkeys. Similar dose-dependent reductions of plasma PKK levels were observed in healthy human volunteers accompanied by decreases in bradykinin generation capacity with an acceptable safety and tolerability profile. These results highlight a novel and specific approach to target PKK for the treatment of HAE and other diseases involving contact system activation and overproduction of bradykinin.

Subcutaneous ofatumumab in patients with relapsing-remitting multiple sclerosis: The MIRROR study.

OBJECTIVE: To assess dose-response effects of the anti-CD20 monoclonal antibody ofatumumab on efficacy and safety outcomes in a phase 2b double-blind study of relapsing forms of multiple sclerosis (RMS). METHODS: Patients (n = 232) were randomized to ofatumumab 3, 30, or 60 mg every 12 weeks, ofatumumab 60 mg every 4 weeks, or placebo for a 24-week treatment period, with a primary endpoint of cumulative number of new gadolinium-enhancing lesions (per brain MRI) at week 12. Relapses and safety/tolerability were assessed, and CD19+ peripheral blood B-lymphocyte counts measured. Safety monitoring continued weeks 24 to 48 with subsequent individualized follow-up evaluating B-cell repletion. RESULTS: The cumulative number of new lesions was reduced by 65% for all ofatumumab dose groups vs placebo (p < 0.001). Post hoc analysis (excluding weeks 1-4) estimated a ≥90% lesion reduction vs placebo (week 12) for all cumulative ofatumumab doses ≥30 mg/12 wk. Dose-dependent CD19 B-cell depletion was observed. Notably, complete depletion was not necessary for a robust treatment effect. The most common adverse event was injection-related reactions (52% ofatumumab, 15% placebo), mild to moderate severity in 97%, most commonly associated with the first dose and diminishing on subsequent dosing. CONCLUSION: Imaging showed that all subcutaneous ofatumumab doses demonstrated efficacy (most robust: cumulative doses ≥30 mg/12 wk), with a safety profile consistent with existing ofatumumab data. This treatment effect also occurred with dosage regimens that only partially depleted circulating B cells. CLASSIFICATION OF EVIDENCE: This study provides Class I evidence that for patients with RMS, ofatumumab decreases the number of new MRI gadolinium-enhancing lesions 12 weeks after treatment initiation.

Safety and efficacy of ofatumumab in relapsing-remitting multiple sclerosis: a phase 2 study.

OBJECTIVES: We present the first study to explore safety and efficacy of the human CD20 monoclonal antibody ofatumumab in relapsing-remitting multiple sclerosis (RRMS). METHODS: In this randomized, double-blind, placebo-controlled study, patients received 2 ofatumumab infusions (100 mg, 300 mg, or 700 mg) or placebo 2 weeks apart. At week 24, patients received alternate treatment. Safety and efficacy were assessed. RESULTS: Thirty-eight patients were randomized (ofatumumab/placebo, n = 26; placebo/ofatumumab, n = 12) and analyzed; 36 completed the study. Two patients in the 300-mg group withdrew from the study because of adverse events. No unexpected safety signals emerged. Infusion-related reactions were common on the first infusion day but not observed on the second infusion day. None of the patients developed human anti-human antibodies. Ofatumumab was associated with profound selective reduction of B cells as measured by CD19(+) expression. New brain MRI lesion activity was suppressed (>99%) in the first 24 weeks after ofatumumab administration (all doses), with statistically significant reductions (p < 0.001) favoring ofatumumab found in new T1 gadolinium-enhancing lesions, total enhancing T1 lesions, and new and/or enlarging T2 lesions. CONCLUSIONS: Ofatumumab (up to 700 mg) given 2 weeks apart was not associated with any unexpected safety concerns and was well tolerated in patients with RRMS. MRI data suggest a clinically meaningful effect of ofatumumab for all doses studied. Results warrant further exploration of ofatumumab in RRMS. CLASSIFICATION OF EVIDENCE: This study provides Class II evidence that in patients with RRMS, ofatumumab compared with placebo does not increase the number of serious adverse events and decreases the number of new MRI lesions.

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.

Randomized trial of sumatriptan and naproxen sodium combination in adolescent migraine.

BACKGROUND: Treatment of adolescent migraine remains a significant unmet medical need. We compared the efficacy and safety of 3 doses of sumatriptan and naproxen sodium (suma/nap) combination tablets to placebo in the acute treatment of adolescent migraine. METHODS: This randomized, parallel group study in 12 to 17 year olds required 2 to 8 migraines per month (typically lasting >3 hours untreated) for ≥ 6 months. Subjects entered a 12-week run-in phase, treating 1 moderate-to-severe migraine (attack 1) with single-blind placebo. Subjects reporting headache pain 2 hours after dosing were randomly assigned into a 12-week double-blind phase, treating 1 moderate-to-severe migraine (attack 2) with placebo (n = 145), suma/nap 10/60 mg (n = 96), 30/180 mg (n = 97), or 85/500 mg (n = 152). The primary end point was the percentage of subjects pain-free at 2 hours. RESULTS: The attack 2 adjusted (age; baseline pain severity) 2-hour pain-free rates were higher with suma/nap 10/60 mg (29%; adjusted P = .003), 30/180 mg (27%; adjusted P = .003), and 85/500 mg (24%; adjusted P = .003) versus placebo (10%). Posthoc primary end-point analyses did not demonstrate differences among the 3 doses or an age-by-treatment interaction. Statistically significant differences were found for 85/500 mg versus placebo for sustained pain-free 2 to 24 hours (23% vs 9%; adjusted P = .008), 2-hour photophobia-free (59% vs 41%; adjusted P = .008), and 2-hour phonophobia-free (60% vs 42%; adjusted P = .008). Analyses of other pain, associated symptoms, rescue medication use, and health outcome end points supported higher efficacy for active doses versus placebo. All active doses were well tolerated. CONCLUSIONS: All doses of suma/nap were well tolerated, providing similarly effective acute treatment of adolescent migraine pain and associated symptoms, as compared with placebo.

Evaluation of the migraine treatment sumatriptan/naproxen sodium on blood pressure following long-term administration.

Anti-inflammatory and pain therapies have been associated with blood pressure (BP) destabilization. Hence, the effects on BP of sumatriptan/naproxen sodium in fixed-dose combination, sumatriptan 85 mg, and naproxen sodium 500 mg administered intermittently for the acute treatment of migraine attacks were assessed. Patients with migraine with or without aura and no history of hypertension were randomized to sumatriptan/naproxen sodium (n=135), sumatriptan (n=136), or naproxen sodium (n=136) to treat migraine attacks for 6 months in a double-blind, parallel-group trial. Following a treated migraine attack, patients performed 2 consecutive days of self-measured BPs beginning ≥24 hours after the last dose of study medication and transmitted them by a transtelephonic modem. The primary end point was the change from baseline in self-measured BP at 6 months. Changes in self-measured BP from baseline to 6 months for sumatriptan/naproxen sodium were -2.1/-1.5 mm Hg (95% confidence intervals, -3.4 to -0.8 for systolic and -2.6 to -0.3 for diastolic). Mean changes from baseline in self-measured BP did not differ among the 3 treatment groups. Additional categorical analyses did not show increases from baseline with sumatriptan/naproxen sodium relative to either of the monotherapy groups. Intermittent acute migraine treatment with sumatriptan/naproxen sodium for up to 6 months was associated with clinically insignificant decreases in self-measured BP that were similar to those with sumatriptan or naproxen alone in normotensive patients with migraine.
