A randomized, double-blind trial assessing the efficacy and safety of two doses of dulaglutide in Japanese participants with type 2 diabetes (AWARD-JPN).

AIM: To assess the efficacy and safety of dulaglutide 1.5 mg versus dulaglutide 0.75 mg in Japanese participants with type 2 diabetes (T2D). MATERIALS AND METHODS: A Phase 3, multicentre, randomized, double-blind, parallel-group study was conducted in Japanese participants aged ≥20 years, with T2D for ≥6 months and inadequate glycaemic control, while on a single oral antihyperglycaemic medication (NCT04809220). The primary objective was to evaluate superiority of dulaglutide 1.5 mg versus dulaglutide 0.75 mg measured by mean change in glycated haemoglobin (HbA1c) from baseline to 26 weeks. Other efficacy and safety endpoints were evaluated at 26 and 52 weeks. All statistical analyses were conducted using the intention-to-treat population. RESULTS: Overall, 591 participants were randomized to once-weekly dulaglutide 1.5 mg or 0.75 mg. At Week 26, dulaglutide 1.5 mg was superior to dulaglutide 0.75 mg in HbA1c reduction from baseline (least squares mean [LSM] difference -0.29% [95% confidence interval {CI} -0.43, -0.14]). At Week 52, the dulaglutide 1.5-mg arm had a significantly greater proportion of participants who achieved HbA1c <7.0% (46.3% vs. 38.5%; p = 0.03) and showed significantly greater reduction in fasting serum glucose (LSM difference -9.4 mg/dL [95% CI -14.4, -4.3]; p < 0.001) versus the dulaglutide 0.75-mg arm. No statistically significant change in body weight was observed in either treatment arm. Overall, 442 participants (75.4%) experienced treatment emergent adverse events (TEAEs). Constipation (11.3%), diarrhoea (9.6%) and pyrexia (9.0%) were the most commonly reported TEAEs. CONCLUSIONS: Dulaglutide 1.5 mg once weekly demonstrated superior glycaemic control versus dulaglutide 0.75 mg once weekly, with comparable safety and tolerability, in Japanese people with T2D.

Clinical Evaluation After Discontinuation of Galcanezumab in Japanese Patients with Episodic and Chronic Migraine: Analysis of a Randomized, Placebo-Controlled Trial and Open-label Extension Study.

INTRODUCTION: This analysis of two Japanese clinical trials evaluated efficacy and safety after galcanezumab (GMB) discontinuation in patients with episodic migraine (EM) and chronic migraine (CM). METHODS: Data were from a 6-month, randomized, double-blind, placebo [PBO]-controlled primary trial (patients with EM) and a 12-month open-label extension trial (patients with EM/CM). Patients received 6 months' (primary) or 12/18 months' (extension) treatment with GMB 120 mg (GMB120) plus 240-mg loading dose or 240 mg (GMB240) with 4 months' post-treatment follow-up. Efficacy was assessed as number of monthly migraine headache days during post-treatment. Safety was assessed via post-treatment-emergent adverse events (PTEAEs). RESULTS: The analysis population included 186 patients from the primary trial (PBO N = 93; GMB120 N = 45; GMB240 N = 48), 220 patients with EM from the extension trial (PBO/GMB120 N = 57; PBO/GMB240 N = 55; GMB120/GMB120 N = 55; GMB240/GMB240 N = 53), and 55 patients with CM (GMB120 N = 28; GMB240 N = 27). In patients with EM receiving 6 months' GMB120, mean standard deviation (SD) monthly migraine headache days increased from 5.69 (4.64) at treatment end to 6.24 (4.37) at end of follow-up but did not return to pre-treatment levels (8.80 [2.96]). In the extension trial, mean monthly migraine headache days in patients with EM receiving GMB120 were 4.13 (3.85) after 12 months and 4.45 (3.78) at end of follow-up, and 3.59 (3.48) after 18 months and 3.91 (3.57) at end of follow-up. Monthly migraine headache days in patients with CM (12 months' GMB120) were 10.71 (4.61) at treatment end and 11.17 (5.64) at end of follow-up (pre-treatment 20.15 [4.65]). Similar results were seen for patients receiving GMB240. The most observed PTEAE after GMB discontinuation was nasopharyngitis. CONCLUSION: Galcanezumab exhibited post-treatment efficacy for up to 4 months in Japanese patients with EM and with CM. No unexpected safety signals were observed.

Long-term treatment with lasmiditan in patients with migraine: post hoc analysis of treatment patterns and outcomes from the open-label extension of the CENTURION randomized trial.

BACKGROUND: The objective of this analysis was to gain new insights into the patient characteristics and other factors associated with lasmiditan usage and clinical outcomes under conditions resembling the real-world setting. METHODS: This was a post hoc analysis of data from the 12-month, open-label extension (OLE) of the phase 3, double-blind, randomized, controlled CENTURION trial, which examined the efficacy and safety of lasmiditan as acute treatment across four migraine attacks. Patients completing the main study who treated ≥ 3 attacks could continue in the OLE. The initial lasmiditan dose was 100 mg, with dose adjustments to 50 mg or 200 mg allowed at the investigator's discretion. Patient and clinical characteristics were summarized by dosing pattern and completion status. Safety was assessed based on adverse event (AE) frequency by number of doses. RESULTS: In total, 445 patients treated ≥ 1 migraine attacks with lasmiditan during the OLE, 321 of whom (72.1%) completed the study. Forty-seven percent of patients remained on the 100-mg initial dose during the OLE whereas 20.2% used both 100 mg and 50 mg, 30.6% used both 100 mg and 200 mg, and 6 (1.3%) used multiple dose levels. All dosing patterns were associated with clinical and patient-reported improvement; however, the 100-mg group had the highest proportion of patients reporting improvement in the Patient Global Impression of Change - Migraine Headache Condition (56.5% vs 33.4%-52.2%). In comparison, all three groups that made dose adjustments had higher rates of completion compared to the 100-mg group (72.1%-83.3% vs 68.9%). The frequency of AEs decreased with continued use of lasmiditan. Concomitant triptans and lasmiditan use did not increase AE frequency. CONCLUSIONS: Based on high persistence and patient satisfaction rates, the 100-mg dose appears optimal for most patients. For those who adjusted dose levels, dose adjustments appeared beneficial to improve efficacy or tolerability, retaining patients on treatment. Collectively, the data suggest that patients who experienced efficacy continued to use lasmiditan regardless of the occurrence or frequency of AEs, and continued use appeared associated with fewer AEs.

Galcanezumab Efficacy Through the Dosing Interval in Japanese Patients with Episodic Migraine: Post Hoc Analysis of a Phase 2 Randomized Trial.

INTRODUCTION: The efficacy and safety of galcanezumab as a preventive treatment in Japanese patients with episodic migraine was demonstrated in a phase 2, randomized, placebo-controlled trial (conducted December 2016-January 2019). This post hoc analysis assessed the consistency of galcanezumab efficacy through the monthly dosing interval. METHODS: Patients with 4-14 migraine headache days/month were randomized (2:1:1, stratified by baseline migraine frequency) to subcutaneous placebo (n = 230), 120-mg galcanezumab (with 240-mg loading dose; n = 115) or 240-mg galcanezumab (n = 114) once monthly for 6 months. Outcomes included change from baseline in weekly migraine headache days, proportion of patients with migraine headache on each day, and proportion of patients with worsening migraine headache days during each month ([average of weeks 3-4] - [average of weeks 1-2] > 0). RESULTS: In the 120-mg (approved dose) galcanezumab group, mean change from baseline in weekly migraine headache days was consistent and significantly greater (p < 0.05) than placebo for weeks 1-4; efficacy was consistent when averaged across months 1-6 and in most individual months. Averaged across months 1-6, the proportion of patients with migraine headache was significantly lower with galcanezumab than placebo on every day in both dose groups and was not significantly different between days 2 and 28 with 120-mg galcanezumab (p = 0.161). Within each month, the proportion of patients with migraine headache was generally consistent from days 2-28. The proportion of patients with worsening during the dosing interval did not significantly exceed 50% in any group during any month. CONCLUSIONS: This post hoc analysis supports the consistency of efficacy of galcanezumab across 6 months of treatment and suggests that wearing-off within the dosing interval does not occur on a population level in Japanese patients with episodic migraine.

Lasmiditan in Japanese Patients with Common Migraine Comorbidities or Concomitant Medications: A Post Hoc Safety and Efficacy Analysis from the MONONOFU Study.

Background: Migraine is often comorbid with other disorders. People with migraine may be prescribed one or more concomitant medications. This post hoc analysis assessed the safety and efficacy of lasmiditan in Japanese people with migraine comorbidities or using concomitant medications. Patients and Methods: The MONONOFU study was a Phase 2, randomized, placebo-controlled, multicenter study of lasmiditan for acute migraine treatment in Japanese adults. Patients reported comorbidities (pre-existing or coexisting conditions) during screening. Concomitant medications (any drugs taken ±48 hours of the study drug) and treatment-emergent adverse events (TEAEs) were recorded in a paper diary. Study drug efficacy (pain freedom 2 hours after administration of study drug) was reported in an eDiary. Logistic regression models were used for subgroup analyses of safety (incidence of TEAEs) and efficacy (pain freedom at 2 hours post dose) of lasmiditan in relation to presence/absence of comorbidities, and safety in relation to concomitant medications. Results: Common comorbidities (occurring in ≥10% of any lasmiditan dose group) were seasonal allergies, allergic rhinitis, tension-type headache, cervicobrachial syndrome, dysmenorrhea, nasopharyngitis, musculoskeletal stiffness, chronic gastritis, constipation, and insomnia. There was no significant interaction of treatment with comorbidity for safety or efficacy. There was also no significant interaction between treatment and concomitant medication groups of special interest (acetaminophen/nonsteroidal anti-inflammatory drugs, triptans, antiemetics, central nervous system depressant medications, serotonergic medications, antiepileptics, antihypertensive medications, Chinese herbal medicines, and contraceptives) for incidence of TEAEs. Conclusion: In Japanese people with migraine, the safety of lasmiditan appeared to be independent of common comorbidities and concomitant medications; efficacy appeared to be independent of comorbid conditions. Clinical Trials Registration: NCT03962738 (ClinicalTrials.gov).

Safety profile of lasmiditan in patients with migraine in an Asian population.

BACKGROUND: MONONOFU, a multicenter, randomized, double-blind, placebo-controlled phase 2 study of Japanese patients with migraine, was pivotal for lasmiditan approval in Japan. However, treatment-emergent adverse events (TEAEs) were more common than in global studies. A detailed safety profile would assist patient management. RESEARCH DESIGN AND METHODS: Safety assessments in MONONOFU included specific terms reported, frequency, severity, time to onset, duration, TEAE management, common TEAE risk factors, and TEAE-efficacy associations. RESULTS: Of 846 participants, 691 were assessed for safety. The proportion of participants reporting ≥1 TEAE was 23.4% with placebo and 70.9% with lasmiditan; 87.3% of TEAEs with lasmiditan were mild. The most frequent TEAEs with lasmiditan, dizziness (39.4%) and somnolence (19.3%), started ≤1 hour postdose (median durations: 2.5 and 3.3 hours, respectively). Higher lasmiditan dose, but not patient factors including body size, was identified as a clinically meaningful predictor of dizziness and somnolence. There were no adverse consequences of neurological TEAEs, which did not appear to adversely affect lasmiditan efficacy. CONCLUSIONS: In the MONONOFU study, TEAEs appeared typically mild, transient, and self-limiting. Lasmiditan may represent a useful and well-tolerated acute treatment option for smaller (body mass index <30 kg/m2) patients and Asian patients with migraine.

Galcanezumab Effects on Migraine Severity and Symptoms in Japanese Patients with Episodic Migraine: Secondary Analysis of a Phase 2 Randomized Trial.

INTRODUCTION: Galcanezumab, a humanized monoclonal antibody against calcitonin gene-related peptide, is a preventive migraine treatment. In global, randomized, placebo-controlled trials, galcanezumab reduced migraine headache severity and the frequency of migraine headaches associated with nausea and/or vomiting, photophobia and phonophobia, prodromal symptoms, or aura. We report secondary analyses from a Japanese phase 2 trial that assessed the effect of galcanezumab on migraine headache severity, frequency of migraine-associated symptoms, and frequency of migraine headaches during menstrual periods in Japanese patients with episodic migraine. METHODS: Adults with migraine (International Classification of Headache Disorders, 3rd edition; 4-14 migraine headache days/month) were randomized (2:1:1) to a monthly placebo (n = 230), 120 mg galcanezumab (240 mg loading dose; n = 115), or 240 mg galcanezumab (n = 114) for 6 months (double-blind). Patients recorded migraine headache days, severity, and symptoms in an electronic diary. Changes from baseline were analyzed (mixed model for repeated measures). RESULTS: Both galcanezumab doses significantly reduced the number of monthly moderate-to-severe and severe migraine headache days compared with placebo, overall (difference in least-squares mean change from baseline, 120 mg/240 mg versus placebo: moderate-to-severe, -1.9/-1.8 days; severe: -0.4/-0.4 days) and in each month; mean severity score was significantly reduced in the 240 mg group. Both galcanezumab doses significantly reduced the number of migraine headache days with nausea/vomiting (-1.1/-1.0 days), photophobia/phonophobia (-2.3/-1.7 days), prodromal symptoms (-0.7/-0.8 days), and aura (-0.7/-0.7 days). In most cases, the proportion of migraine headache days with these symptoms was reduced by galcanezumab. Both galcanezumab doses reduced the number of migraine headache days occurring during menstrual periods (n = 269; -0.8/-0.9 days). CONCLUSION: Once-monthly galcanezumab significantly reduced the frequency of migraine headache days with moderate-to-severe or severe headache, migraine headache days with migraine-associated symptoms, and migraine headache days during menstrual periods in Japanese patients with episodic migraine, consistent with results from global studies.

Efficacy of Lasmiditan Across Patient and Migraine Characteristics in Japanese Patients with Migraine: A Secondary Analysis of the MONONOFU Trial.

INTRODUCTION: This MONONOFU trial subgroup analysis evaluates the efficacy of lasmiditan across patient and migraine characteristics in Japanese patients with migraine. METHODS: MONONOFU trial was a multicenter, randomized, double-blind, placebo-controlled study. The patients were randomly assigned in a 3:7:6:7 ratio to receive lasmiditan 50 mg, 100 mg, 200 mg, or placebo for a single migraine attack within 4 h of pain onset. Efficacy of lasmiditan vs placebo was evaluated at 2 h post dose for proportion of patients with headache pain freedom. Efficacy was assessed across patient characteristics (age, sex, body weight, cardiovascular risk factors (CVRF), and comorbidity of tension-type headache), migraine disease characteristics (history of migraine with aura, migraine prevention therapy, triptan response, and triptan use or nonuse), and migraine attack characteristics (headache severity, aggressive headache, attack during perimenstrual period, time to dosing, time of dosing, experienced treatment-emergent adverse event (TEAE) of dizziness, and experienced TEAE of somnolence). Logistic regression was used; all subgroup analyses were not analyzed with multiplicity-adjusted statistical tests. RESULTS: Treatment-by-subgroup interactions (by each arm) were not significant (p ≥ 0.05) for pain freedom at 2 h post dose across all patient subgroups and lasmiditan doses, except for CVRF (100 mg and 200 mg), migraine with aura (50 mg), triptan response (50 mg), and time to dosing (200 mg). Treatment-by-subgroup interactions (by overall) were not significant (p ≥ 0.05) for pain freedom at 2 h post dose across all patient subgroups, except for CVRFs. Higher proportions of patients were pain free at 2 h post dose when treated with lasmiditan (50 mg, 100 mg, and 200 mg) versus placebo, irrespective of most patient characteristics, migraine disease characteristics, and migraine attack characteristics. CONCLUSION: Although few interactions were observed, lasmiditan could be a promising acute treatment option in a wide range of Japanese patients with migraine, as efficacy is not generally influenced by patient and migraine characteristics.

Rapid Onset and Sustained Efficacy of Lasmiditan Among Japanese Patients with Migraine: Prespecified Analyses of a Randomized Controlled Trial.

INTRODUCTION: Rapid onset and sustained efficacy are important for acute migraine treatment. Global phase 3 trials have demonstrated the early onset and sustained efficacy of the 5-HT1F receptor agonist lasmiditan. In this prespecified analysis of the MONONOFU study, we assessed the onset and sustained efficacy of lasmiditan in Japanese patients with migraine. METHODS: MONONOFU was a multicenter, randomized, placebo-controlled, phase 2 study conducted in Japan (May 2019-June 2020). Eligible adults with migraine (N = 846; modified intent-to-treat population, N = 682) were randomized 7:3:7:6 to placebo, lasmiditan 50 mg, 100 mg, or 200 mg, taken orally within 4 h of moderate-to-severe migraine onset. Patients recorded headache severity and symptoms predose and 0.5-48 h postdose. Sustained and modified sustained pain freedom were defined as patients who were headache pain-free 2 h postdose and had no pain (sustained pain freedom) or had mild or no pain (modified sustained pain freedom) at 24 or 48 h without rescue/recurrence medications. Efficacy outcomes were analyzed by logistic regression. Patients also recorded the actual time of pain-free and of meaningful pain relief (Kaplan-Meier analysis). RESULTS: Compared with placebo, significantly more lasmiditan-treated (100 or 200 mg) patients were headache pain-free, had pain relief, were free of their most bothersome symptom, or had total migraine freedom (no headache or migraine-associated symptoms) within 30-60 min. Median time to pain-free was 9.26, 6.88, 2.75, and 2.30 h in placebo, 50-mg, 100-mg, and 200-mg lasmiditan groups, respectively. Significantly greater proportions of patients treated with 100 (19.7-29.5%) or 200 mg (21.1-35.7%) lasmiditan had sustained or modified sustained pain freedom at 24 or 48 h compared with placebo (10.4-15.8%). CONCLUSION: This prespecified analysis of data from MONONOFU has confirmed that the efficacy of lasmiditan is rapid in onset and sustained in patients with moderate-to-severe migraine in Japan.

Safety and efficacy of tirzepatide as an add-on to single oral antihyperglycaemic medication in patients with type 2 diabetes in Japan (SURPASS J-combo): a multicentre, randomised, open-label, parallel-group, phase 3 trial.

BACKGROUND: Due to potential ethnic differences in the pathophysiology of type 2 diabetes, new therapeutics need to be evaluated in Japanese patients. We aimed to assess the safety and glycaemic efficacy of tirzepatide as an add-on treatment in Japanese patients with type 2 diabetes who had inadequate glycaemic control with stable doses of various oral antihyperglycaemic monotherapies. METHODS: This multicentre, open-label, parallel-group, randomised, phase 3 trial was conducted at 34 medical research centres and hospitals in Japan. Eligible participants were aged 20 years or older with inadequately controlled (HbA1c ≥7·0% to <11·0%) type 2 diabetes and were receiving oral antihyperglycaemic monotherapy (sulfonylureas, biguanides, α-glucosidase inhibitors, thiazolidinedione, glinides, or SGLT2 inhibitors) for at least 3 months (stable dose for ≥8 weeks before screening), had a BMI of 23 kg/m2 or higher, and stable bodyweight (±5%) for at least 3 months before screening. After a 2-week screening and 2-week lead-in period, all participants were randomly assigned (1:1:1) to receive 5, 10, or 15 mg of tirzepatide, administered once per week subcutaneously for 52 weeks followed by a 4 week safety follow-up period, using a computer-generated random sequence and interactive web response system, stratified by oral antihyperglycaemic medication group. All participants started receiving 2·5 mg tirzepatide and doses were escalated by 2·5 mg every 4 weeks until the assigned dose was reached. The primary endpoint was safety and tolerability during 52 weeks of treatment, assessed as incidence of treatment-emergent adverse events in the modified intention-to-treat (mITT) population. This trial is registered with ClinicalTrials.gov, NCT03861039. FINDINGS: Between March 30, 2019, and Feb 16, 2021, with recruitment and enrolment continuing until Feb 4, 2020, 484 participants were assessed for eligibility and 443 were randomly assigned to receive at least one dose of tirzepatide (148 [33%] in the 5 mg group, 147 [33%] in the 10 mg group, and 148 [33%] in the 15 mg group). 398 (90%) participants completed the study and treatment. Most participants (343 [77%] of 443) had at least one treatment-emergent adverse event. Treatment-emergent adverse events were more frequent in the tirzepatide 15 mg group (125 [84%] of 148) than the 5 mg (109 [74%] of 148) and 10 mg groups (109 [74%] of 147). The most frequent treatment-emergent adverse events with tirzepatide were mild or moderate nasopharyngitis (75 [17%]), nausea (74 [17%]), constipation (54 [12%]), diarrhoea (51 [12%]), and decreased appetite (44 [10%]). At week 52, mean changes from baseline in bodyweight were -3·8 kg (SE 0·5; -5·1% reduction) in the 5 mg group, -7·5 kg (0·5; -10·1% reduction) in the 10 mg group, and -10·2 kg (0·5; -13·2% reduction) in the 15 mg group. Least squares mean HbA1c at baseline reduced from 8·5% (SE 0·1) to 6·0% (0·1) in the 5 mg tirzepatide group, from 8·6% (0·1) to 5·6% (0·1) in the 10 mg group, and from 8·6% (0·1) to 5·6% (0·1) in the 15 mg group at week 52. No adjudication-confirmed deaths were reported. INTERPRETATION: Tirzepatide was well tolerated as an add-on to oral antihyperglycaemic monotherapy in Japanese participants with type 2 diabetes and showed improvement in glycaemic control and bodyweight, irrespective of background oral antihyperglycaemic medication. Tirzepatide is a potential new treatment option for Japanese patients with type 2 diabetes that is inadequately controlled with single oral antihyperglycaemic medication.

Lasmiditan for single migraine attack in Japanese patients with cardiovascular risk factors: subgroup analysis of a phase 2 randomized placebo-controlled trial.

BACKGROUND: Some migraine treatments are contraindicated for patients with cardiovascular disease (CVD) or risk factors (CVRFs). We report safety and efficacy of lasmiditan, a new oral acute migraine treatment with no cardiovascular contraindication, in Japanese patients with CVRFs. RESEARCH DESIGN AND METHODS: MONONOFU was a multicenter, randomized, double-blind, placebo-controlled, phase 2 study of Japanese patients with migraine (met International Headache Society criteria, Migraine Disability Assessment score ≥11, disabling migraine for ≥1 year). Eligible patients were randomized (7:3:7:6) to placebo or lasmiditan 50, 100, 200 mg. This prespecified analysis described CVDs, CVRFs, and cardiovascular treatment-emergent adverse events (TEAEs). Efficacy (proportion pain-free, experienced pain relief, most bothersome symptom-free, or disability-free 2 hours post-dose) was evaluated within CVRF subgroups (≤1, ≥2). RESULTS: Of 846 randomized patients, 691 were analyzed (CVRF≤1: 375; CVRF≥2: 316). The proportion of lasmiditan-treated patients with ≥1 TEAE was not related to CVRF numbers. Eighteen (3.8%) lasmiditan-treated and three (1.4%) placebo-treated patients reported likely cardiovascular TEAEs. Lasmiditan was more effective than placebo at relieving pain, symptoms, and disability in both CVRF subgroups. There was no consistent relationship between CVRF subgroups and efficacy. CONCLUSIONS: Lasmiditan was well tolerated and effective in Japanese patients with migraine and CVRFs. TRIAL REGISTRATION: ClinicalTrials.gov: NCT03962738.

Early Onset and Maintenance Effect of Galcanezumab in Japanese Patients with Episodic Migraine.

PURPOSE: This study aimed to extensively evaluate the onset and maintenance effect of galcanezumab compared with placebo for the prevention of episodic migraine in Japanese patients. PATIENTS AND METHODS: This was a post-hoc analysis of a Phase 2, multicenter, randomized, double-blind, placebo-controlled study conducted between December 2016 and January 2019 (ClinicalTrials.gov: NCT02959177). Patients aged between 18 and 65 years with episodic migraine were randomized to receive a monthly injection of galcanezumab (120 mg: N = 115, 240 mg: N = 114) or placebo (N = 230) for 6 months. Outcome measures included onset of effect at weekly and daily intervals-assessed by change from baseline in the number of migraine headache days and the proportion of patients with migraine headache-with galcanezumab versus placebo. To further confirm the onset and maintenance effect, the 50% response rate was also evaluated. RESULTS: The mean change from baseline in weekly migraine headache days was significantly reduced with galcanezumab (-0.97 days) compared with placebo (-0.10 days) at week 1 (p ≤ 0.0001), which was maintained at all subsequent weeks up to week 4 (all p ≤ 0.0001 vs placebo). A significantly smaller proportion of galcanezumab-treated patients had migraine headache compared with placebo-treated patients at day 1 after the first injection (13.6% vs 31.4%, respectively; p ≤ 0.0001), which was also maintained at all subsequent days during the first week after the first injection. Furthermore, the 50% response rate was significantly higher with galcanezumab compared with placebo from week 1 through month 6. CONCLUSION: The onset of the migraine preventive effect of galcanezumab was rapid compared with placebo, starting from day 1 after the first injection in Japanese patients with episodic migraine. The effect was maintained during the first week and first month, and throughout 6 months of monthly injections of galcanezumab. Galcanezumab is a promising preventive treatment in Japanese patients with episodic migraine.

Treatment Satisfaction of Galcanezumab in Japanese Patients with Episodic Migraine: A Phase 2 Randomized Controlled Study.

INTRODUCTION: This analysis evaluated the treatment satisfaction of Japanese patients receiving galcanezumab (GMB) as a preventive medication for episodic migraine (4-14 monthly migraine headache days). METHODS: This phase 2, randomized, double-blind, placebo-controlled study enrolled patients aged 18-65 years at 40 centers in Japan. Patients were randomized 2:1:1 to receive monthly subcutaneous injections of placebo (PBO, n = 230), GMB 120 mg (n = 115), or GMB 240 mg (n = 114) for 6 months. Patients' experience with treatment was measured using the Patient Global Impression of Severity (PGI-S), Patient Global Impression of Improvement (PGI-I), and Patient Satisfaction with Medication Questionnaire-Modified (PSMQ-M) scales. PGI-S was administered at baseline and months 1-6, PGI-I at months 1-6, and PSMQ-M at months 1 and 6. Prespecified analyses were differences between GMB and PBO in PGI-I and the change from baseline in PGI-S, and evaluating positive responses for the PGI-I and PSMQ-M. RESULTS: Average change ± SE from baseline across months 1-6 was - 0.09 ± 0.05 (PBO), - 0.17 ± 0.07 (GMB 120 mg, p = 0.33), and - 0.30 ± 0.07 (GMB 240 mg, p = 0.013) for PGI-S. Average PGI-I across months 1-6 was 3.39 ± 0.05 (PBO), 2.55 ± 0.07 (GMB 120 mg, p < 0.05), and 2.71 ± 0.07 (GMB 240 mg, p < 0.05). Reductions of 2.8-3.0 monthly migraine headache days corresponded to 25-31% higher positive PGI-I response rates with GMB compared with PBO. Positive PSMQ-M response rates for satisfaction and preference were statistically significantly higher for GMB compared with PBO (odds ratio [95% confidence interval], all p < 0.05 vs. PBO): satisfaction GMB 120 mg (3.142 [1.936-5.098]) and GMB 240 mg (3.924 [2.417-6.369]), and preference GMB 120 mg (3.691 [2.265-6.017]) and GMB 240 mg (3.510 [2.180-5.652]). CONCLUSION: Japanese patients with episodic migraine receiving preventive treatment with GMB are significantly more satisfied than those receiving PBO.

A long-term open-label safety study of galcanezumab in Japanese patients with migraine.

BACKGROUND: Because of the burden of migraine in Japan, there is a need for safe and effective preventive treatments. This study assessed the long-term safety and tolerability of galcanezumab in Japanese patients with episodic (EM) or chronic (CM) migraine. RESEARCH DESIGN AND METHODS: In this 12-month open-label study, adult patients with EM who previously completed a 6-month, double-blind, placebo-controlled trial were newly randomized to either galcanezumab dose from placebo or continued their assigned galcanezumab doses (all: 120 mg, n = 120; 240 mg, n = 126). Newly enrolled patients with CM were randomized to 120-mg (n = 32) or 240-mg (n = 33) galcanezumab. The primary outcome was long-term safety and tolerability. RESULTS: The incidence of TEAEs was similar between treatment groups. Nasopharyngitis was the most common TEAE, followed by injection site reactions. The discontinuation rate was low (EM = 9.3%; CM = 15.4%) and no deaths were reported. Patients with EM who received galcanezumab in the placebo-controlled trial had sustained efficacy. Both doses reduced the number of migraine headache days in patients with CM. CONCLUSIONS: Long-term treatment with 120-mg or 240-mg galcanezumab was safe and effective in Japanese patients with EM or CM.

Migraine-Specific Quality-of-Life Questionnaire (MSQ) Version 2.1 Score Improvement in Japanese Patients with Episodic Migraine by Galcanezumab Treatment: Japan Phase 2 Study.

PURPOSE: Evaluate changes from baseline in health-related quality of life (QoL) in Japanese patients with episodic migraine receiving preventive treatment with galcanezumab (GMB). PATIENTS AND METHODS: Preventive treatments for migraine have been shown to improve QoL, but few clinical trials have examined QoL outcomes in Japanese patients. This phase 2, randomized, double-blind, placebo-controlled study was conducted at 40 centers in Japan. Patients aged 18-65 years with episodic migraine (4-14 monthly migraine headache days) received GMB 120 mg (n=115), 240 mg (n=114), or placebo (PBO, n=230) as monthly subcutaneous injections for 6 months. QoL was measured monthly using the Migraine-Specific Quality-of-Life Questionnaire (MSQ) version 2.1. Prespecified analyses were differences between GMB and PBO for change from baseline in all 3 domains of the MSQ and MSQ-Total, for each month and the average over Months 4-6. RESULTS: Treatment with GMB significantly increased MSQ scores from baseline vs PBO. Average change ± SE from baseline across Months 4-6 was 10.12±0.72 (PBO), 17.13±1.03 (GMB 120 mg; P<0.001), and 15.91±1.03 (GMB 240 mg; P<0.001) for MSQ Role Function-Restrictive; 4.80±0.65 (PBO), 9.64±0.93 (GMB 120 mg; P<0.001), and 8.35±0.93 (GMB 240 mg; P<0.05) for MSQ Role Function-Preventive (MSQ-RFP); 3.46±0.77 (PBO), 10.04±1.10 (GMB 120 mg; P<0.001), and 7.73±1.10 (GMB 240 mg; P<0.05) for MSQ Emotional Function, and 7.14±0.67 (PBO), 13.46±0.95 (GMB 120 mg; P<0.001), and 11.98±0.95 (GMB 240 mg; P<0.001) for MSQ-Total. Significantly greater improvement in scores in all MSQ domains and MSQ-Total was observed for both GMB doses vs PBO at Month 1 and was maintained for Months 1-6 (excluding Month 5 for MSQ-RFP). CONCLUSION: Preventive treatment with GMB 120 mg/240 mg improves MSQ scores in Japanese patients with episodic migraine. Improvements were seen within the first month and maintained for 6 months and are similar to those seen in global studies enrolling primarily Caucasian patients.

Effect of First-line S-1 Plus Oxaliplatin With or Without Ramucirumab Followed by Paclitaxel Plus Ramucirumab on Advanced Gastric Cancer in East Asia: The Phase 2 RAINSTORM Randomized Clinical Trial.

Importance: Ramucirumab, a human IgG 1 antibody against vascular endothelial growth factor receptor 2, has been shown to improve progression-free survival and overall survival in patients with advanced gastric cancer in the second-line setting. Objective: To compare progression-free survival for S-1 and oxaliplatin plus ramucirumab with that for S-1 and oxaliplatin plus placebo in patients with advanced gastric cancer. Design, Setting, and Participants: This phase 2, double-blind randomized clinical trial (RAINSTORM [First-line S-1 Plus Oxaliplatin With or Without Ramucirumab Followed by Paclitaxel Plus Ramucirumab in Patients With Advanced Gastric Cancer]) was conducted from October 12, 2015, to April 11, 2018, at 36 sites in Japan, South Korea, and Taiwan. Participants were chemotherapy-naive patients (n = 189) with metastatic gastric or gastroesophageal adenocarcinoma. Analyses of the full analysis set and safety population were conducted between November 27, 2017, and June 4, 2018. Interventions: Patients randomized to the ramucirumab plus S-1 and oxaliplatin arm received S-1, 80 to 120 mg/d twice daily, on days 1 to 14 and oxaliplatin, 100 mg/m2, on day 1 with ramucirumab, 8 mg/kg, on days 1 and 8 in part A (21-day cycle). Patients randomized to the placebo plus S-1 and oxaliplatin arm received the same S-1 and oxaliplatin dosage as well as placebo on days 1 and 8 in part A. Eligible patients received second-line paclitaxel, 80 mg/m2, on days 1, 8, and 15 and ramucirumab, 8 mg/kg, on days 1 and 15 in part B (28-day cycle). Main Outcomes and Measures: The primary end point was progression-free survival, analyzed using the stratified log-rank test; the hazard ratio (HR) was estimated using the stratified Cox proportional hazards regression model. Secondary end points included overall survival and adverse events. Results: In total, 189 patients were randomized and received treatment: 96 to the ramucirumab plus S-1 and oxaliplatin arm and 93 to the placebo plus S-1 and oxaliplatin arm. Among the 189 patients, 121 (64.0%) were male, and the median (range) age was 62.0 (26-84) years. Median progression-free survival was not prolonged in the ramucirumab plus S-1 and oxaliplatin arm compared with the placebo plus S-1 and oxaliplatin arm (6.34 [80% CI, 5.65-6.93] vs 6.74 [80% CI, 5.75-7.13] months; HR, 1.07; 80% CI, 0.86-1.33; P = .70). Median overall survival was 14.65 (80% CI, 12.39-15.67) months in the ramucirumab plus S-1 and oxaliplatin arm and 14.26 (80% CI, 13.83-17.31) months in the placebo plus S-1 and oxaliplatin arm (HR, 1.11; 80% CI, 0.89-1.40; P = .55). The most commonly reported grade 3 or higher treatment-emergent adverse events in the ramucirumab plus S-1 and oxaliplatin arm in part A were decreased neutrophil count (14 patients [14.6%]), hypertension (10 patients [10.4%]), and anemia (10 patients [10.4%]). Conclusions and Relevance: In this randomized clinical trial, the addition of ramucirumab to first-line S-1 and oxaliplatin treatment did not prolong progression-free survival or overall survival compared with S-1 and oxaliplatin alone among East Asian patients with advanced gastric cancer; no new safety signals for ramucirumab were identified.

Early improvement of storage or voiding symptoms by tadalafil predicts treatment outcomes in patients with lower urinary tract symptoms from benign prostatic hyperplasia.

OBJECTIVES: To determine whether early changes in International Prostate Symptom Score predict final improvement in the quality of life and treatment satisfaction of patients with lower urinary tract symptoms from benign prostatic hyperplasia receiving tadalafil. METHODS: This post-hoc analysis of three randomized-controlled trials of tadalafil for lower urinary tract symptoms from benign prostatic hyperplasia used subpopulations based on treatment status (tadalafil, placebo) and region (Japan, Asia). Logistic regression, principal component analysis and hierarchical clustering analysis were applied to individual International Prostate Symptom Score and Patient Global Impression of Improvement response scores. RESULTS: From logistic regression, most individual International Prostate Symptom Score items predicted either International Prostate Symptom Score remitter or responder status; only International Prostate Symptom Score Quality of Life predicted Patient Global Impression of Improvement responder status in tadalafil-treated patients. Among tadalafil-treated patients, principal component analysis showewd that improvement of International Prostate Symptom Score items 2, 4, 7 and International Prostate Symptom Score Quality of Life at early visits were associated with Patient Global Impression of Improvement (final visit), whereas International Prostate Symptom Score items 1, 3, 5 and 6 at early visits were associated with total International Prostate Symptom Score at the final visit. No clear predictive items for Patient Global Impression of Improvement and total International Prostate Symptom Score existed for placebo-treated patients. Hierarchical clustering analysis showed that the closest association was between International Prostate Symptom Score Quality of Life and International Prostate Symptom Score item 7 in placebo- and tadalafil-treated patients, which supports the principal component analysis results. CONCLUSIONS: Early changes of storage and voiding symptoms by tadalafil might lead to treatment satisfaction and overall International Prostate Symptom Score improvement, respectively. This finding could help physicians predict tadalafil treatment outcomes for patients with lower urinary tract symptoms from benign prostatic hyperplasia.

Trajectories of depression symptom improvement and associated predictor analysis: An analysis of duloxetine in double-blind placebo-controlled trials.

BACKGROUND: In the treatment of major depressive disorder (MDD), it is not fully understood how individual symptoms improve over time (trajectory) in remitters. This study compared symptom improvement trajectories, as measured with the 17-item Hamilton Depression Rating Scale (HAM-D17), in remitters and nonremitters. METHODS: This analysis is based on 10 placebo-controlled, randomized, double-blind trials of duloxetine (40-60mg/day) for treatment of MDD from baseline up to week 8. Remission was defined as a HAM-D17 total score ≤7 at week 8 (last observation carried forward). Trajectories of HAM-D17 items were assessed by mixed model repeated measures analysis for treatment and remitter-nonremitter comparisons. Grouping of the trajectories was performed by factor analysis. Predictor analysis using HAM-D17 items was conducted by logistic regression. RESULTS: There were 1555 patients in the duloxetine group (489 [31.4%] remitters) and 1206 patients in the placebo group (290 [24.0%] remitters; P<.0001). For most items, the difference in trajectories between remitters and nonremitters appeared at early time points and increased over time. Treatment response trajectories were very similar for duloxetine and placebo remitters, while duloxetine nonremitters improved more than placebo nonremitters. For duloxetine remitters, we found 3 trajectory groups of HAM-D17 items. The predictor analysis showed that improvement in 6 individual items at week 1 or 2 was significantly associated with remission at week 8. LIMITATIONS: Generalizability of these results may be limited by the relatively short observation period used to define remission. CONCLUSIONS: Early monitoring of some symptoms of depression may prove useful in guiding treatment decisions.

A 1-year safety study of dulaglutide in Japanese patients with type 2 diabetes on a single oral hypoglycemic agent: an open-label, nonrandomized, phase 3 trial.

The goal of this study was to assess the safety and efficacy of 0.75 mg of dulaglutide, a once weekly glucagon-like peptide-1 receptor agonist, in Japanese patients with type 2 diabetes (T2D) on a single oral hypoglycemic agent (OHA). In this phase 3, nonrandomized, open-label, parallel-group, 52-week study, safety and efficacy of once weekly dulaglutide 0.75 mg were assessed in Japanese patients with T2D on a single OHA (sulfonylureas [SU], biguanides [BG], α-glucosidase inhibitors [AGI], thiazolidinedione [TZD], or glinides [GLN]). A total of 394 patients were treated with study drug, and 92.9% completed the 52-week treatment period. The most frequent treatment-emergent adverse events were nasopharyngitis and gastrointestinal disorders, including constipation, diarrhea, and nausea. Incidences of hypoglycemia varied across the combination therapy groups: incidence was greater in patients receiving SU compared with other combinations. No severe hypoglycemic episodes occurred during the study. Increases from baseline in pancreatic and total amylase, lipase, and pulse rate were observed in all 5 combination therapy groups. Significant reductions from baseline in HbA1c were observed in all 5 combination therapy groups (-1.57% to -1.69%, p < 0.001 for all). Mean body weight changes from baseline varied across the combination therapy groups: a significant increase was observed in combination with TZD, there were no significant changes in combination with SU or GLN, and significant reductions were observed in combination with BG or AGI. Once weekly dulaglutide 0.75 mg in combination with a single OHA was overall well tolerated and improved glycemic control in Japanese patients with T2D.
