Introduction: Demographic and clinical variables were examined in a post hoc analysis of the PROlonged Migraine Prevention with Topiramate (PROMPT) study to determine potential contribution to relapse. Methods: After a six-month open-label (OL) topiramate phase, patients were randomised to continue topiramate or switch to placebo in a six-month double-blind (DB) phase. ‘Relapse’ was investigated in terms of change in monthly migraine days after randomisation compared with the month before randomisation, and was analysed during the first (‘initial relapse’) and last month (‘sustained relapse’) of the DB phase. More than 40 potential predicting factors were entered into analyses of variance and covariance. Results: For initial relapse, variable-by-treatment interactions were significant for the Headache Impact Test (HIT-6) at DB baseline, and decline in acute medication intake or reporting of ‘anxiety’ in the OL phase. For sustained relapse, no statistically significant interactions were observed. Conclusion: Relapse after topiramate discontinuation in migraine prophylaxis appears to be unaffected by patient characteristics or baseline migraine frequency.

IntroductionTo assess efficacy of erenumab in the first three months of the open-label extension phase (OLEP; 13–24 weeks) of the LIBERTY study.MethodsIn the double-blind treatment phase (DBTP), 246 patients were randomized to placebo and erenumab 140 mg for 12 weeks, following which, patients completing that phase (N=240) were enrolled in OLEP, to receive monthly erenumab 140 mg. Outcomes measured monthly throughout to week 24 were achievement of at least 50%/75%/100% reduction in monthly migraine days (MMD), change from DBTP baseline in MMD, monthly acute migraine-specific medication days (MSMD), Headache Impact Test (HIT-6TM) total score, everyday activities (EA) and physical impairment (PI) as measured by the Migraine Physical Function Impact Diary (MPFID).ResultsOverall, 228/240(95.0%) patients completed the 24 week visit of the OLEP. In the overall population at Week 24, 39.2%, 15.9% and 7.0% patients achieved ≥50%/≥75%/100% reduction in MMD. The mean (standard deviation) change from DBTP baseline in MMD was −2.7(4.4) and −1.4(3.0) in MSMD; and −7.6(8.0), −2.5(9.2) and −4.0(9.0) in HIT-6TM, MPFID-PI and MPFID-EA scores respectively. Patients with continuous use of erenumab showed sustained efficacy in all outcomes assessed. Patients who switched from placebo to erenumab in the OLEP showed improvement from the first measurement at Week 16 on all outcomes assessed.ConclusionsEfficacy of erenumab was sustained throughout 24 weeks in a hard to treat patient population with multiple prior preventive treatment failures. Overall, efficacy data over 24 weeks (assessed over weeks 13–16,17–20 and 21–24) was generally in line with prior erenumab trials.

Abstract Background Galcanezumab is a calcitonin gene-related peptide (CGRP) monoclonal antibody (mAb) indicated for the preventive treatment of migraine. While galcanezumab has demonstrated efficacy in patients who did not respond to prior preventive medications in general, its efficacy in patients who did not benefit from individual, commonly prescribed preventive treatments due to inadequate efficacy or safety/tolerability remains unknown. Methods CONQUER was a 3-month, randomized, double-blind, placebo-controlled, phase 3b study that enrolled patients with episodic or chronic migraine who had 2 to 4 migraine preventive medication category failures in the past 10 years. Patients were randomly assigned 1:1 to receive placebo (N = 230) or galcanezumab 120 mg/month (240 mg loading dose; N = 232). Post hoc analyses were conducted to determine the efficacy of galcanezumab in patients who had not benefited from six of the most commonly prescribed migraine preventive medications. The mean change from baseline in monthly migraine headache days and ≥ 50 % response rates were assessed over months 1–3. Improvement in Migraine-Specific Questionnaire Role Function-Restrictive (MSQ-RFR) scores were assessed at month 3. The endpoints were estimated via mixed model with repeated measures. Results The most common treatment failures due to inadequate efficacy or safety/tolerability, which at least 20 % of patients reported trying without benefit, included topiramate, amitriptyline, propranolol, valproate or divalproex, onabotulinum toxin A, and metoprolol. Patients who had not previously benefited from these treatments had a greater mean reduction in monthly migraine headache days across months 1–3 in the galcanezumab group compared to placebo (all p < 0.01). More patients treated with galcanezumab experienced a ≥ 50 % reduction from baseline in monthly migraine headache days across months 1–3 compared to placebo (all p < 0.05). Galcanezumab-treated patients had a greater improvement in mean MSQ-RFR scores at month 3 compared to placebo (all p < 0.01). Conclusions In this population, galcanezumab was effective in reducing monthly migraine headache days, improving response rates, and enhancing quality of life in patients who had not previously benefited from topiramate, amitriptyline, propranolol, valproate or divalproex, onabotulinum toxin A, and/or metoprolol due to inadequate efficacy or safety/tolerability.

BACKGROUND: Tetrahydrobiopterin (6R-BH4) is a cofactor for nitric oxide (NO) synthesis. Reduced BH4 bioavailability uncouples NO synthase, decreases NO production, increases superoxide production, and may contribute to hypertension. 6R-BH4 administration has been shown to lower blood pressure (BP) and improve endothelial function in animal models and in two small, open-label clinical studies. A randomized, placebo-controlled, multicenter, parallel study was designed (‘CONTROL’) to evaluate the antihypertensive effects of 6R-BH4 in patients with treated, but poorly controlled, hypertension. METHODS: A total of 116 subjects with hypertension (SBP/DBP> 135/85) despite a stable regimen of at least two antihypertensive drugs were randomized 2:1 to oral 6R-BH4 (n=77) or placebo (n=39) and stratified by presence or absence of type 2 diabetes. Subjects received a daily dose of 10 mg/kg 6R-BH4 for 8 weeks. Endpoints were change from baseline in SBP and DBP over 8 weeks of treatment. Other measures of efficacy included change in insulin sensitivity, proteinuria, and biochemical markers of oxidative stress and NO production. RESULTS: 6R-BH4-treated subjects had a 4.4-mm Hg drop in SBP (baseline mean, 145 mm Hg) compared with a 6.4-mm Hg drop in placebo-treated subjects (baseline mean, 143 mm Hg; p=0.428). 6R-BH4-treated subjects had a 5.0-mm Hg drop in DBP (baseline mean, 90 mm Hg) compared with a 4.8-mm Hg drop in placebo-treated subjects (baseline mean, 93 mm Hg; p=0.907). No statistically significant differences in either endpoint were seen in subgroup analyses of subjects with or without diabetes, or in other measures of efficacy or safety. Post-hoc analyses in subjects with higher SBP at baseline (>150 mm Hg) showed a better SBP response to 6R-BH4 (−14.1 mm Hg) than to placebo (−5.9 mm Hg) however too few subjects with higher SBP were enrolled to reach statistical significance (6R-BH4, n=19; placebo, n=7: p=0.149). CONCLUSIONS: Oral 6R-BH4 at a dose of 10 mg/kg/day showed no anti-hypertensive effect in subjects already on a stable regimen of at least two antihypertensive drugs.

1 Background: A post-hoc analysis of pooled data from two randomized, double-blind studies and their open-label extensions evaluated whether baseline characteristics and efficacy endpoints differ between cancer and noncancer adults with advanced illness and opioid-induced constipation treated with methylnaltrexone (MNTX) or placebo. Methods: Patients received SC MNTX 0.15 mg/kg or placebo (study 302) and SC MNTX 8 mg (38≤62 kg), 12 mg (≥62 kg), or placebo (study 4,000) every other day for two weeks and received the same doses of MNTX as needed during the first 2 weeks of the open-label extensions. Double-blind populations were stratified by those with/without cancer. Efficacy endpoints included rescue-free bowel movements (RFBMs) within 4 hours after each dose for ≥2 of the first 4 doses; time to rescue-free laxation; rescue laxatives use; and ≥3 RFBMs/week and ≥1 RFBM/week in ≥3 of 4 weeks. Results: Median baseline opioid use (mg/day) was greater in cancer (187.9 placebo [n=114]; 180.0 MNTX [n=116]) versus noncancer patients (80.0 placebo [n=71]; 120.0 MNTX [n=62]). MNTX significantly ( P<0.0001) improved the proportion of cancer (56.9%) and noncancer (58.1%) patients with an RFBM within 4 hours after each dose for ≥ two of the first four doses versus placebo (5.3% cancer; 11.3% noncancer). Median time to laxation was significantly ( P≤0.0002) shorter in cancer (0.96 hours) and noncancer (1.25 hours) patients 24 hours after the first dose of MNTX versus placebo (22.53 and >24 hours, respectively). Rescue laxatives were used by 39.7% of cancer and 30.6% of noncancer MNTX patients versus 51.8% of cancer and 39.4% of noncancer placebo patients. Of 108 open-label extension double-blind MNTX patients, 79 (73.1%) achieved ≥3 RFBMs/week with ≥1 RFBM/week increase in ≥ three of four weeks versus 48 (46.6%) of 103 double-blind placebo patients (data from double-blind and first two weeks of open-label). Conclusions: MNTX treatment improved the laxation response, with a faster onset of laxation in patients with and without cancer, and reduced the need for rescue laxatives vs placebo. Improvements over placebo continued into the first two weeks of the open-label extensions for MNTX-treated patients. Clinical trial information: NCT00672477, NCT00402038.

ObjectiveTo present, post hoc analyses from a controlled, prospective study of predominant negative symptoms (PNS) of schizophrenia on baseline patient characteristics, severity of symptoms and their variability among participating countries.MethodsData were analyzed from a phase 3, randomized, double-blind, active-controlled, parallel-group study in adult PNS patients with schizophrenia (EudraCT Number 2012-005485-36). Subjects with a PANSS factor score for negative symptoms (PANSS-FSNS) ≥ 24 and no pseudo-specific factors (e.g. high positive symptoms, extrapyramidal symptoms, depression) were randomized to cariprazine 4.5 mg/d (dose range: 3–6 mg/d) or risperidone 4 mg/d (dose range: 3–6 mg/d) for 26 weeks. Baseline values of PANSS-FSNS, individual PANSS items, personal and social performance (PSP), and clinical global impression of severity (CGI-S) were analyzed based on the data gained from 11 European participating countries.ResultsAverage PANSS-FSNS of patients was 27.6 ± 2.48, reflecting severe negative symptoms. Patients were moderately ill (CGI-S 4.2 ± 0.75), with marked difficulties (PSP 48.4 ± 10.78) predominantly in social functioning. The investigated patient population was fairly homogeneous as shown by small variability in all three scores. Moreover, baseline values in the 11 countries presented low variability while number of enrolled patients per country showed high variance (n = 7–118). Narrative description of symptoms and individual PANSS items rated as most severe and prominent were in high correlation.ConclusionPost hoc evaluation of this predominant negative symptom study showed that, this patient population can be identified reliably by psychiatrist. Additional training on the judgment of personal and social relationships can increase the diagnostic accuracy.Disclosure of interestEmployee of Gedeon Richter Plc.

ObjectiveTo evaluate individual and group long-term efficacy and safety of erenumab in individuals with episodic migraine (EM) for whom 2–4 prior preventatives had failed.MethodsParticipants completing the 12-week double-blind treatment phase (DBTP) of the LIBERTY study could continue into an open-label extension phase (OLEP) receiving erenumab 140 mg monthly for up to 3 years. Main outcomes assessed at week 112 were: ≥50%, ≥75% and 100% reduction in monthly migraine days (MMD) as group responder rate and individual responder rates, MMD change from baseline, safety and tolerability.ResultsOverall 240/246 (97.6%) entered the OLEP (118 continuing erenumab, 122 switching from placebo). In total 181/240 (75.4%) reached 112 weeks, 24.6% discontinued, mainly due to lack of efficacy (44.0%), participant decision (37.0%) and adverse events (AEs; 12.0%). The ≥50% responder rate was 57.2% (99/173) at 112 weeks. Of ≥50% responders at the end of the DBTP, 36/52 (69.2%) remained responders at ≥50% and 22/52 (42.3%) at >80% of visits. Of the non-responders at the end of the DBTP, 60/185 (32.4%) converted to ≥50% responders in at least half the visits and 24/185 (13.0%) converted to ≥50% responders in >80% of visits. Change from baseline at 112 weeks in mean (SD) MMD was −4.2 (5.0) days. Common AEs (≥10%) were nasopharyngitis, influenza and back pain.ConclusionsEfficacy was sustained over 112 weeks in individuals with difficult-to-treat EM for whom 2–4 prior migraine preventives had failed. Erenumab treatment was safe and well tolerated, in-line with previous studies.Trial registration numberNCT03096834

Background We evaluated the effect of erenumab, a fully human monoclonal antibody that inhibits the canonical calcitonin gene-related peptide receptor, on migraine-related disability, impact, and health-related quality of life among patients with episodic migraine. Methods Patients enrolled in a phase 3, 6-month, double-blind, placebo-controlled study of once-monthly erenumab 70 and 140 mg for migraine prevention (STRIVE) used an eDiary during the baseline and double-blind treatment phases to complete validated, specific questionnaires, including the modified (monthly) Migraine Disability Assessment Questionnaire; Headache Impact Test; and Migraine-Specific Quality of Life Questionnaire-role function-restrictive (MSQ-RFR), -role function-preventive (MSQ-RFP), and -emotional function (MSQ-EF). Results A total of 955 patients were randomized to receive erenumab 70 mg (n = 317), erenumab 140 mg (n = 319), or placebo (n = 319). Erenumab versus placebo resulted in significantly greater improvements in all patient-reported outcomes; changes from baseline were numerically higher with 140 mg erenumab. Improvements occurred rapidly and were maintained over 6 months of treatment. Between-group differences from placebo over months 4–6 for the 70- and 140-mg dose groups were, respectively, −2.1 and −2.8 for modified (monthly) Migraine Disability Assessment Questionnaire, −2.1 and −2.3 for Headache Impact Test, 5.1 and 6.5 for MSQ-RFR, 4.2 and 5.4 for MSQ-RFP, and 5.2 and 6.7 for MSQ-EF ( p < 0.001 for all). Erenumab also significantly reduced the proportion of patients with severe and very severe migraine-related disability and increased the proportion of patients with clinically meaningful improvements in migraine-related impact and health-related quality of life. Conclusion Erenumab reduced migraine disability and impact and improved patients’ health-related quality of life, reinforcing its role as a promising new therapy for migraine prevention.

Objective:To assess long-term safety and efficacy of anti–calcitonin gene-related peptide receptor erenumab in patients with episodic migraine (EM).Methods:Patients enrolled in a 12-week, double-blind, placebo-controlled clinical trial (NCT01952574) who continued in an open-label extension (OLE) study will receive erenumab 70 mg every 4 weeks for up to 5 years. This preplanned interim analysis, conducted after all participants had completed the 1-year open-label follow-up, evaluated changes in monthly migraine days (MMD), achievement of ≥50%, ≥75%, and 100% reductions, Headache Impact Test (HIT-6) score, Migraine-Specific Quality of Life (MSQ), Migraine Disability Assessment (MIDAS), and safety. Data reported as observed without imputation for missing data.Results:Of 472 patients enrolled in the parent study, 383 continued in the OLE with a median exposure to erenumab of 575 days (range 28–822 days). Mean (SD) MMD were 8.8 (2.6) at parent study baseline, 6.3 (4.2) at week 12 (beginning of OLE), and 3.7 (4.0) at week 64 (mean change from baseline [reduction] of 5.0 days). At week 64, 65%, 42%, and 26% achieved ≥50%, ≥75%, and 100% reduction in MMD, respectively. Mean HIT-6 scores were 60.2 (6.3) at baseline and 51.7 (9.2) at week 64. MSQ and MIDAS improvements from baseline were maintained through week 64. Safety profiles during the OLE were similar to those in the double-blind phase, which overall were similar to placebo.Conclusions:One-year efficacy, supported by functional improvements and favorable safety and tolerability profiles, supports further investigation of erenumab as a preventive treatment in patients with EM.Clinicaltrials.gov identifier:NCT01952574.Classification of evidence:This study provides Class IV evidence that for patients with episodic migraine, erenumab reduces long-term MMD and improves headache-related disability and migraine-specific quality of life.

Abstract Background Erenumab, a fully human monoclonal antibody directed against the calcitonin gene-related peptide receptor, was approved for the prevention of episodic (EM) or chronic migraine (CM) at the monthly dose of 70 mg or 140 mg. We reviewed the available literature to understand if patients with prior preventive treatment failures benefit more from the 140 mg dose than the 70 mg. Main body We searched papers indexed in PubMed and conference abstracts published in the last 2 years which assessed the safety and efficacy of erenumab in patients with prior preventive treatment failures. We reviewed the results of 3 randomized controlled trials and their subgroup analyses and open-label extensions. The 140 mg monthly dose of erenumab had a numerical advantage over the 70 mg monthly dose in patients with prior preventive treatment failures, both in EM and CM (with or without medication overuse) during the double blind phases of the trials and their open-label extensions. The numerical difference between the two doses increased with the increase in the number of prior preventive treatment failures. Conclusions The available data suggest that erenumab 140 mg monthly might be preferred over the 70 mg monthly dose in patients with EM or CM and prior preventive treatment failures. Further data are needed to assess the long-term efficacy in clinical practice of the two doses of erenumab, while their safety profile is comparable.
