Project description:ObjectiveTo characterize adult patients with episodic migraine who achieved 100% response to galcanezumab treatment.BackgroundGalcanezumab is a humanized monoclonal antibody that selectively binds to the calcitonin gene-related peptide (CGRP) and has demonstrated efficacy in reducing migraine headache days (MHD) in patients with episodic and chronic migraine.MethodsA post hoc analysis of the proportion of patients with 100% response (100% reduction from baseline in monthly MHD) was calculated for each month from pooled data of 2 double-blind, 6-month galcanezumab studies in patients with episodic migraine (4 to 14 MHD and ≥2 migraine attacks per month at baseline). The patients were randomized (1:1:2) to monthly subcutaneous galcanezumab, 120 mg (after 240 mg initial loading dose) or 240 mg, or placebo. A generalized linear mixed model with effects for baseline MHD, treatment, month, and treatment-by-month interaction was used to estimate the mean monthly response rate.ResultsThe analysis included 1739 patients treated with galcanezumab, 120 mg (n = 436) or 240 mg (n = 428), or placebo (n = 875). The mean monthly 100% response rate on an average month in the 6-month double-blind phase was greater for galcanezumab 120 mg (13.5%) and 240 mg (14.3%) groups vs placebo (5.9%) with odds ratios of 2.5 (95% confidence interval [CI] 1.9, 3.2) and 2.6 (95% CI 2.0, 3.4), respectively (P < .001). The rate of 100% monthly response increased at each month over the 6-month double-blind phase with higher rates for galcanezumab dose groups (9 to 21%) than placebo (2 to 10%) (P < .02). Evaluation of 100% response by the number of months showed a greater proportion of galcanezumab-treated patients in either dose group, compared to placebo, were able to achieve a 100% response (P < .001 up to 3 months); however, though greater than placebo, few galcanezumab patients had ≥4 months of 100% response (P < .02). The proportions of patients with 100% response were greatest in the last 3 months of the treatment. Considering the average number days between nonconsecutive MHD across the 6-month period (not just during the times of 100% response), the duration of migraine headache-free periods in the galcanezumab groups was 29 days for those with at least 1 month of 100% response and 55 days for those with at least 3 months of 100% response. This gap was approximately 6 to 11 times greater than the mean gap of 5 days observed at baseline.ConclusionsMore than a third of the patients with episodic migraine treated with galcanezumab 120 mg or 240 mg achieved 100% response for at least 1 month. More patients had 100% monthly response in the last 3 months of the 6-month double-blind period. For those with 100% response for at least 1 month, the average time between nonconsecutive MHD for the entire treatment period was nearly 1 month and approached 2 months for patients with 3 or more months of 100% response.

Project description:PurposeThis 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 methodsThis 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.ResultsThe 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.ConclusionThe 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.

Project description:BackgroundGalcanezumab, a humanized monoclonal antibody that binds calcitonin gene-related peptide, has demonstrated a significant reduction in monthly migraine headache days compared with placebo. Here, we analyze data from 3 randomized clinical trials (2 episodic trials [EVOLVE-1, EVOLVE-2] and 1 chronic trial [REGAIN]), to examine if galcanezumab also alleviates the severity and symptoms of migraine.MethodsThe episodic migraine trials were 6-month, double-blind studies in patients with episodic migraine (4-14 monthly migraine headache days). The chronic migraine trial was a 3-month, double-blind study in patients with chronic migraine (≥ 15 headache days per month, where ≥ 8 met criteria for migraine). Patients (18-65 years) were randomized to placebo or galcanezumab 120 mg with a 240-mg loading dose or 240 mg. Patients recorded headache characteristics, duration, severity, and presence of associated symptoms with each headache. The outcomes analyzed were changes from baseline in number of monthly migraine headache days with nausea and/or vomiting, photophobia and phonophobia, aura, and prodromal symptoms other than aura. Additional outcomes analyzed included the number of moderate-to-severe monthly migraine headache days, number of severe migraine headache days, and mean severity of remaining migraine headache days. Change from baseline in the proportion of days with nausea and/or vomiting and the proportion of days with photophobia and phonophobia among the remaining monthly migraine headache days were also analyzed.ResultsGalcanezumab was superior to placebo in reducing the frequency of migraine headache days with associated symptoms of migraine such as nausea and/or vomiting, photophobia and phonophobia, and prodromal symptoms. Galcanezumab reduced the frequency of migraine headache days with aura in the episodic migraine studies. There was a significant reduction in the proportion of remaining migraine headache days with nausea and/or vomiting for the episodic and chronic migraine studies, and with photophobia and phonophobia for the episodic migraine studies. Galcanezumab was superior to placebo in reducing the number of monthly moderate-to-severe migraine headache days and the overall and monthly severe migraine headache days.ConclusionsGalcanezumab reduces the frequency of migraine headache days and can alleviate potentially disabling non-pain symptoms on days when migraine is present in patients with episodic or chronic migraine.Trial registrationNCT, NCT02614183 (EVOLVE-1), registered 25 November 2015; NCT, NCT02614196 , (EVOLVE-2), registered 25 November 2015; NCT, NCT02614261 (REGAIN), registered 25 November 2015.

Project description:IntroductionThis analysis evaluated the treatment satisfaction of Japanese patients receiving galcanezumab (GMB) as a preventive medication for episodic migraine (4-14 monthly migraine headache days).MethodsThis 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.ResultsAverage 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]).ConclusionJapanese patients with episodic migraine receiving preventive treatment with GMB are significantly more satisfied than those receiving PBO.Trial registrationClinicalTrials.gov, NCT02959177 (registered November 7, 2016).

Project description:IntroductionGalcanezumab, 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.MethodsAdults 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).ResultsBoth 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).ConclusionOnce-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.Trial registrationClinicalTrials.gov (NCT02959177).

Project description:ObjectiveTo assess the efficacy of erenumab at the ≥50%, ≥75%, and 100% reduction in monthly migraine days (MMD) response thresholds, using data from the 6-month double-blind treatment phase (DBTP) of the Study to Evaluate the Efficacy and Safety of Erenumab in Migraine Prevention (STRIVE) pivotal clinical trial.MethodsEnrolled patients with episodic migraine (EM; ≥4 MMD and <15 monthly headache days) were randomized (1:1:1) to erenumab 70 mg (n = 312), erenumab 140 mg (n = 318), or placebo (n = 316) once monthly. We determined the proportions of patients with ≥50%, ≥75% and 100% reduction in MMD over the last 3 months of the STRIVE DBTP (months 4 through 6) and conducted post hoc analyses to contextualize the treatment benefit in patient subgroups achieving, and not achieving, these response thresholds. Outcome measures included changes in MMD, acute migraine-specific medication days (MSMD), and patient-reported outcomes.ResultsThe proportions of patients with a reduction in MMD from baseline were greater for erenumab than for placebo at all response thresholds. As previously reported for the ≥50% response threshold, 135/312 (43.3%) of patients on erenumab 70 mg and 159/318 (50.0%) on erenumab 140 mg responded, vs 84/316 (26.6%) for placebo. At months 4 through 6, 65/312 (20.8%) and 70/318 (22.0%) of those on erenumab 70 mg and erenumab 140 mg, respectively, achieved ≥75% reductions vs 25/316 (7.9%) on placebo. A reduction of 100% response, which required no migraine days over 3 consecutive months based on observed data, was achieved by 10/312 (3.2%) of patients treated with erenumab 70 mg and 16/318 (5.0%) for erenumab 140 mg, vs 9/316 (2.8%) for placebo. At all response thresholds, responders achieved numerically greater reductions in mean MMD and MSMD, and greater improvements in disability than did the overall population; importantly, these remarkable responses were noted early. Meanwhile, 60/312 (19.2%) and 53/318 (16.7%) patients on erenumab 70 and 140 mg, respectively, had no reduction in MMD from baseline in months 4 through 6, compared with 104/316 (32.9%) patients on placebo.ConclusionsThe responses at the ≥50%, ≥75%, and 100% thresholds provide context for establishing realistic patient and physician expectations regarding the magnitude of treatment benefit that may be achieved by patients with EM responding to erenumab (STRIVE, NCT02456740).

Project description:BackgroundThe phase 3 randomized PERSIST study demonstrated the efficacy and tolerability of galcanezumab, a humanized anti-calcitonin gene-related peptide (CGRP) monoclonal antibody for prevention of episodic migraines. We present findings from the open-label extension (OLE) of PERSIST, which evaluated the long-term efficacy and safety of galcanezumab in patients from China, India, and Russia.MethodsPatients completing the 3-month double-blind period of PERSIST were eligible for the 3-month OLE. Patients previously randomized to galcanezumab (GMB/GMB group) continued to receive galcanezumab 120 mg at all three visits during the OLE whereas patients randomized to placebo received a 240 mg loading dose of galcanezumab and then two 120 mg doses (PBO/GMB group). The primary outcome was the mean change (from double-blind baseline) in the number of monthly migraine headache days (MHDs) to month 6. Other endpoints included percent reduction in monthly MHDs from double-blind baseline to month 6, functional outcomes, safety and tolerability.ResultsOverall, 99% of patients completing the double-blind period entered the OLE, and 96% completed through month 6. Patients in the GMB/GMB group achieved continued improvements in efficacy, with the reduction from baseline in the mean number of monthly MHDs, and slightly increasing from 4.01 days at the end of the double-blind period to 4.62 at the end of the OLE. Of patients who were ≥ 50% responders to galcanezumab at month 3, 66% maintained this response through to month 6. Patients in the PBO/GMB group experienced a rapid reduction in the number of monthly MHDs after initiation of galcanezumab, with a mean reduction from baseline of 4.56 days by month 6. The long-term benefits of galcanezumab were also supported by improvements in other efficacy and functional endpoints. All safety findings were consistent with the known long-term safety profile of galcanezumab; no patients experienced a treatment-related serious adverse event.ConclusionsGalcanezumab was efficacious and well-tolerated in patients with episodic migraine from China, India and Russia, for up to 6 months.Trial registrationClinicalTrisABSTRACT_pals.gov NCT03963232, registered May 24, 2019.

Project description:BackgroundGalcanezumab, a humanized monoclonal antibody that binds calcitonin gene-related peptide, has demonstrated efficacy and good tolerability in patients with episodic migraine in previous phase 3 trials. We report results from the PERSIST study, which was designed to assess the efficacy and safety of galcanezumab in patients with episodic migraine from China, India, and Russia.MethodsThis phase 3 study was conducted at 40 centers in China (n = 26), India (n = 10), and Russia (n = 4). Eligible adult patients with episodic migraine were randomized in a 1:1 ratio to receive monthly galcanezumab 120 mg (with 240 mg loading dose) or placebo during a double-blind, 3-month treatment period. The primary endpoint was the overall mean change from baseline in monthly migraine headache days (MHDs). Key secondary endpoints were the mean proportion of patients with ≥ 50%, ≥ 75%, and 100% reductions from baseline in MHDs and mean change in the Migraine-Specific Quality of Life Questionnaire (MSQ) Role Function-Restrictive domain score.ResultsIn total, 520 patients were randomized and received at least one dose of galcanezumab (N = 261) or placebo (N = 259). The least squares (LS) mean reduction from baseline in monthly MHDs over 3 months was significantly greater with galcanezumab compared with placebo (-3.81 days vs. -1.99 days; p < 0.0001). Significantly greater mean proportions of patients with galcanezumab versus placebo had ≥ 50%, ≥ 75%, and 100% reductions from baseline in MHDs (all p < 0.0001). The overall mean improvement from baseline in MSQ Role Function-Restrictive score over 3 months was significantly greater with galcanezumab versus placebo (p < 0.0001). There were no clinically meaningful differences between the galcanezumab and placebo group on any safety parameters except for a higher incidence of injection site pruritus (5.0% vs. 0.0%), injection site reaction (3.8% vs. 0.4%), and injection site discomfort (2.3% vs. 0.0%). TEAEs related to injection sites were mild in severity, except in 1 patient who had a moderate injection site reaction. Six serious adverse events were reported by 6 patients (2 galcanezumab, 4 placebo).ConclusionsGalcanezumab 120 mg once monthly was effective and well tolerated in patients with episodic migraine from China, India, and Russia.Trial registrationClinicalTrials.gov Identifier NCT03963232 (PERSIST), registered May 24, 2019.
