Kollewe K, Gaul C, Gendolla A, Sommer K. Real-life use of onabotulinumtoxinA reduces healthcare resource utilization in individuals with chronic migraine: the REPOSE study. J Headache Pain 2021; 22:50. [PMID: 34078259 PMCID: PMC8173963 DOI: 10.1186/s10194-021-01260-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2021] [Accepted: 05/14/2021] [Indexed: 01/14/2023] Open
Abstract
Background Chronic migraine (CM) is associated with substantial economic burden. Real-world data suggests that onabotulinumtoxinA treatment for CM reduces healthcare resource utilisation (HRU) and related costs. Methods REPOSE was a 2-year prospective, multicentre, non-interventional, observational study to describe the real-world use of onabotulinumtoxinA in adult patients with CM. This analysis examined the impact of onabotulinumtoxinA on HRU. Patients received onabotulinumtoxinA treatment approximately every 12 weeks according to their physicians’ discretion, guided by the summary of product characteristics (SPC) and PREEMPT injection paradigm. HRU outcome measures were collected at baseline and all administration visits and included headache-related hospitalizations and healthcare professional (HCP) visits. Health economic data, including family doctor and specialist visits, inpatient treatment for headache, acupuncture, technical diagnostics, use of nonpharmacologic remedies, and work productivity were also collected for patients enrolled at German study centres. Results Overall, 641 patients were enrolled at 78 study centres across 7 countries (Germany, UK, Italy, Spain, Norway, Sweden, and Russia), 633 received ≥1 onabotulinumtoxinA dose, and 128 completed the 2-year study. Patients were, on average, aged 45 years, 85% were female, and 60% (n = 377) were from Germany. At the end of the 2-year observation period, significantly fewer patients reported headache-related hospitalizations (p < 0.02) and HCP visits (p < 0.001) within the past 3 months than in the 3 months before baseline. In the German population, reductions were observed across all health services at all follow-up visits compared with baseline. The percentage of patients who saw a family doctor decreased from 41.7% at baseline to 13.5% at administration visit 8 and visits to a medical specialist decreased from 61.7% to 5.2% of patients. Inpatient acute treatment and technical diagnostics declined from 6.4% and 19.7% of patients at baseline to 0.0% and 1.0% at administration 8, respectively. The use of nonpharmacologic remedies and medication for the acute treatment of migraine also decreased with continued onabotulinumtoxinA treatment. Work incapacity, disability, absenteeism, and impaired performance at school/work improved with onabotulinumtoxinA treatment for CM over the 2-year observation period. Conclusions Real-world evidence from REPOSE demonstrates that onabotulinumtoxinA treatment is associated with decreased HRU and supports the long-term benefits associated with the use of onabotulinumtoxinA for CM in clinical practice.

Abstract
Background There is currently a wide therapeutic arsenal for migraine patients, without a single first-line preventive drug and we choose the different available alternatives taking into account comorbidities, national guidelines, previous treatments and personal experiences. Our objective was to evaluate the differences in the use of migraine treatments between neurologists from different countries. Methods This is a multi-centre observational study carried out by neurologists from specialized headache units in seven countries, retrospective with consecutive inclusion of all patients presenting with a migraine diagnosis, over a period of three months. Results A total of 734 patients were recruited but only 600 were considered in the analysis in order to homogenize the patient cohorts from countries: 200 Spain (ES), 100 Italy (IT), 85 Russia (RUS), 80 Germany (DE), 60 Portugal (PT), 45 Poland (PL) and 30 Australia (AU). 85.4 % of patients were women with a mean age of 42.6 ± 11.8 years. Considering previous and current preventive treatment, the order of use was: antidepressants (69.3 %), antiepileptic drugs (54.7 %), beta-blockers and antihypertensive drugs (49.7 %), OnabotulinumtoxinA (44.0 %) and others (36.2 %). Statistically significant differences were found between all pharmacological classes: antidepressants were commonly used in all countries, with the exception of Poland (AU: 76.7 %, IT: 71.0 %, DE: 60.0 %, PL: 31.1 %, PT: 71.7 %, RUS: 70.6 %, ES: 78.5 %; p < 0.0001); antiepileptic drugs were more frequently prescribed in Portugal, Australia and Spain (AU: 73.3 %, IT: 40.0 %, DE: 37.5 %, PL: 48.9 %, PT: 85.0 %, RUS: 29.4 % and ES: 69.0 %; p < 0.0001); beta-blockers and antihypertensive drugs were frequently used in all countries except Italy (AU: 60.0 %, IT: 14.0 %, DE: 53.8 %, PL: 48.9 %, PT: 68.3 %, RUS: 49.4 % and ES: 59.0 %; p < 0.0001); BTX-A were predominately used in Spain, Italy and Australia (AU:56.7 %, IT:58.0 %, DE:20.0 %, PL: 42.2 %, PT: 26.7 %, RUS: 24.7 % and ES: 58.5 %; p < 0.0001) and others were most frequently used in Poland (AU: 0.0 %, IT: 19.0 %, DE: 42.5 %, PL: 95.6 %, PT: 31.7 %, RUS: 3.5 % and ES: 49.5 %; p < 0.0001). If only patients without comorbidities are considered (200/600), statistically differences between countries persist in all preventive treatments. Conclusions There is heterogeneity in the choice of preventive treatment between different countries. Prospective comparative studies of the different oral and subcutaneous alternatives would help to create a global therapeutic algorithm that would guarantee the best option for our patients.

Abstract
OBJECTIVE Linear headache has been recently described as an episodic or chronic unilateral pain distributed along a fixed linear trajectory, which combines some characteristics of epicrania fugax and nummular headache. The aim of this study was to describe the clinical characteristics and therapeutic response of a series of 16 new patients. DESIGN This is an observational study with a series of cases. SETTING The study period encompassed June 2014 to June 2019. Demographic, clinical, and therapeutic response data were recorded. METHODS We included all consecutive patients who presented pain with the following characteristics: sharply contoured, fixed in size and shape, with linear shape, without movement along a trajectory, and not circumscribed to the territory of any nerve. RESULTS Twelve patients were women, and four were men. The mean age at onset was 40.1 years. Pain was described as pressing in seven patients, burning in five, and electric or stabbing in two each. Symptomatic treatment had been used by 13 patients (81.2%), with analgesics being the most frequent treatment used. Thirteen patients received preventive treatment. The response to oral medications and anesthetic blockade was insufficient. OnabotulinumtoxinA was used in six cases, with an optimal (>75%) response observed in half. CONCLUSION Linear headache appears to be a distinct headache syndrome from epicrania fugax or nummular headache. Preventive treatment is often required. The drug with the best response was onabotulinumtoxinA.

Abstract
PURPOSE OF REVIEW While traditionally encountered in ambulatory settings, bruxism occurs in patients with a variety of acute neurologic illnesses including encephalitis, intracerebral hemorrhage, traumatic brain injury, hypoxic-ischemic encephalopathy, and acute ischemic stroke. Untreated bruxism in acute neurologic illness can lead to tooth loss, difficulty in mouth care resulting in recurrent aspiration pneumonia, endotracheal tube dislodgement, and even tongue laceration or amputation. Inpatient clinicians should be aware of the etiologies and management strategies for bruxism secondary to acute neurologic illness. RECENT FINDINGS Management strategies for bruxism are varied and include pharmacologic and non-pharmacologic therapies in addition to onabotulinumtoxinA (BoNT-A). Bruxism impacts patients with a variety of acute neurologic illnesses, and emerging evidence suggests successful and safe treatment strategies.

Abstract
BACKGROUND Hemifacial spasm (HFS) is a chronic, potentially disabling disorder that often requires long-term management with botulinum toxin (BoNT). In a country where healthcare costs limit compliance to medical follow-up and treatment, the study aims to provide a real-world experience on the use of BoNT for HFS among Filipinos. METHODS We retrospectively collected data from 162 HFS patients who received 1138 botulinum toxin (BoNT) injections from 2006 to 2019 in our movement disorders center in the Philippines. We described their clinical profile and treatment response. RESULTS The mean age at onset of disease was 47.7 ± 10.72 years. Majority of the patients reported a baseline moderate disease severity and disease frequency of >75% of waking time (59.8% and 46.9%, respectively). Most patients (61.73%) received 5 or less injections during the follow-up period. The mean duration of follow-up was 2.96 ± 4.28 years. The overall duration of treatment effect per injection was 3.6 ± 1.3 months while the mean interval between injections was 6 ± 5 months. There was no difference in the symptom improvement and duration between onabotulinumtoxinA and abobotulinumtoxinA. Side effects were infrequent. CONCLUSION This study supports existing evidence on the efficacy and safety of BoNT for the symptomatic relief of HFS. In the Philippines, long-term treatment with BoNT may be limited by the cost of the procedure as majority of our patients had a few injections with long treatment intervals.

Abstract
BACKGROUND Migraine and depression are highly prevalent and partly overlapping disorders that cause strong limitations in daily life. Patients tend to respond poorly to the therapies available for these diseases. OnabotulinumtoxinA has been proven to be an effective treatment for both migraine and depression. While many studies have addressed the effect of onabotulinumtoxinA in migraine or depression separately, a growing body of evidence suggests beneficial effects also for patients comorbid with migraine and depression. The current meta-analysis systematically investigates to what extent onabotulinumtoxinA is efficient in migraineurs with depression. METHODS A systematic literature search was performed based on PubMed, Scopus and Web of Science from the earliest date till October [Formula: see text], 2020. Mean, standard deviation (SD) and sample size have been used to evaluate improvement in depressive symptoms and migraine using random-effects empirical Bayes model. RESULTS Our search retrieved 259 studies, eight of which met the inclusion criteria. OnabotulinumtoxinA injections administered to patients with both chronic migraine and major depressive disorder led to mean reduction of [Formula: see text] points (CI [[Formula: see text]], [Formula: see text]) in the BDI scale, of [Formula: see text] points (CI [[Formula: see text]], [Formula: see text]) in the BDI-II scale and of [Formula: see text] points (CI [[Formula: see text]], [Formula: see text]) in the PHQ-9 scale, when evaluating depressive symptoms. In the case of the migraine-related symptoms, we found mean reductions of [Formula: see text] (CI [[Formula: see text]], [Formula: see text]) points in the HIT6 scale, [Formula: see text] (CI [[Formula: see text]], [Formula: see text]) in the MIDAS scale, [Formula: see text] (CI [[Formula: see text]], [Formula: see text]) points in the VAS scale and of [Formula: see text] (CI [[Formula: see text]], [Formula: see text]) migraine episodes per month. Comorbid patients showed slightly better improvements in BDI, HIT6 scores and migraine frequency compared to monomorbid patients. The latter group manifested better results in MIDAS and VAS scores. CONCLUSION Treatment with onabotulinumtoxinA leads to a significant reduction of disease severity of both chronic migraine and major depressive disorder in patients comorbid with both diseases. Comparative analyses suggest an equivalent strong effect in monomorbid and comorbid patients, with beneficial effects specifically seen for certain migraine features.

Abstract
Introduction OnabotulinumtoxinA (BT-A) quarterly was the first treatment approved specifically for chronic migraine (CM). It is unclear whether three cycles are better than two to assess early BT-A response. Methods We performed a retrospective analysis on real-life prospectively collected data in 16 European headache centers. All the centers provided data on patients treated with BT-A for CM over the first three cycles of treatment. For each treatment cycle we defined patients as “good responders” if reporting a ≥ 50% reduction in monthly headache days compared with the three months before starting BT-A, “partial responders” if reporting a 30–49% reduction in monthly headache days, and “non-responders” if reporting a < 30% reduction in monthly headache days or stopping the treatment before the third cycle. Results We included 2879 patients. Seven hundred and eighty-four (64.6%) of the 1213 patients reporting a good response during the first and/or the second cycle had a good response during the third cycle; 309 (49.3%) of the 627 patients reporting a partial response (but no good response) during the first and/or the second cycle had a good response during the third cycle; only 65 (6.3%) of the 1039 patients who did not respond during both the first two cycles achieved a good response during the third cycle. Multivariate analyses showed that partial or good response during the first or the second cycle were independently associated with good response during the third cycle. Conclusions Our data suggest that patients with CM responding to BT-A during the first two cycles will likely benefit from the third cycle of treatment, while the probability that non-responders to the first two cycles start responding during the third cycle is low. These results can help guide the individual decision to stop or continue treatment after the second cycle in patients who have not responded to the first two cycles.

Abstract
Background Face-to-face procedures have been postponed during COVID-19 pandemic. We aim to evaluate the impact of onabotulinumtoxinA follow-up delay in migraine during COVID-19 pandemic. Methods Subjective worsening, intensity of migraine attacks, and frequency of headache and migraine were retrospectively compared between patients with unmodified and interrupted onabotulinumtoxinA follow-up in Headache Units. Results We included 67 patients with chronic migraine or high-frequency episodic migraine under onabotulinumtoxinA treatment, 65 (97.0%) female, 44.5 ± 12.1 years old. Treatment administration was voluntarily delayed in 14 (20.9%) patients and nine (13.4%) were unable to continue follow-up. Patients with uninterrupted follow-up during lockdown presented 7.6 and 8.1 less monthly days with headache (adjusted p = 0.017) and migraine attacks (adjusted p = 0.009) compared to patients whose follow-up was interrupted, respectively. Conclusion Involuntary delay of onabotulinumtoxinA follow-up in patients with migraine due to COVID-19 pandemic was associated with a higher frequency of headache and migraine attacks. Safe administration of onabotulinumtoxinA during lockdown should be promoted. Supplementary Information The online version contains supplementary material available at 10.1007/s10072-021-05180-8.

Abstract
PURPOSE To compare the safety and durability of a single intravesical trigonal-only versus 20 trigone-sparing injections of OnabotulinumtoxinA (BTA) for refractory OAB. METHODS A chart review of all idiopathic OAB patients treated with BTA from January 2016 to December 2018 was performed. Outcomes measures included: inter-injection interval, post-void residual (PVR), urinary tract infections (UTI), urinary retention requiring catheterization, and procedure time (min). Statistical analyses were performed using independent sample t-tests. RESULTS Baseline characteristics were comparable for the two groups, data on 69 treatments (19 patients trigone-only) were compared to 105 treatments (26 patients trigone-sparing). There were no differences in the inter-injection intervals or rates of UTI. The trigone-only group exhibited a lower mean PVR (113 ml vs 160 ml, p < 0.02), lower proportion with PVR > 150 ml (23% vs. 39%, p < 0.03), lower rate of urinary retention (5.3% vs. 17.4%, p < 0.02), and shorter procedure time (4.3 min vs. 5.7 min, p < 0.01). There were no cases of vesico-ureteral reflux. CONCLUSION While interpretation remains speculative, the results of this observational study suggest that a single trigone-only injection appears to be as safe and durable as multiple trigone-sparing injections but maybe quicker to perform and appears to have a lower impact on voiding function. Larger series and adequately powered prospective randomized clinical trials are warranted to validate the findings of this pilot study.

Abstract
Background The CGRP antagonists offer a novel therapeutic approach in migraine. Their utility in patients with severe forms of chronic migraine is a subject of particular interest. We present outcomes of 9 months of erenumab treatment in a cohort of patients with difficult-to-control chronic migraine, all of whom had prior unsatisfactory response to onabotulinumtoxinA. Methods We offered erenumab to 98 patients with a prior unsatisfactory response to onabotulinumtoxinA. Eighty of 98 had trialled greater occipital nerve injections (82%), 32/98 peripheral neurostimulation (33%) and 18/98 intravenous dihydroergotamine (18%). Thirty eight of 98 (39%) met the definition of triptan overuse and 43/98 (44%) analgesic overuse. All patients met the EHF criteria for ‘resistant migraine’. Outcome measures (recorded monthly) included days with headache limiting activities of daily living (“red”), not limiting (“amber”), headache free (“green”), and requiring triptans or other analgesics. Quality of life scores - headache impact test 6 (HIT-6), patient health questionnaire 9 (PHQ-9) and pain disability index (PDI) - were also measured. Results Mean number of red days improved by − 6.4 days (SE 0.67, 95%CI − 7.7 to − 5.1, p=0.001) at 3 months; − 6.8 days (SE 0.96, 95%CI − 8.80 to − 4.9, p=0.001) at 6 months and − 6.5 days (SE 0.86, 95%CI − 8.3 to − 4.8, p=0.001) at 9 months. Repeated measures ANOVA confirmed improvements in the number of red (p=0.001), green (p=0.001), triptan (p=0.001) and painkiller days (p=0.001) as well as scores of the HIT-6 (p=0.001), PHQ-9 (p=0.001), and PDI (p=0.001) across the duration of study. Conclusion We observed improvements in pain, medication use and quality of life in onabotulinumtoxinA-resistant chronic migraine patients following erenumab treatment.

Abstract
Introduction: Symptoms of cervical dystonia (CD) can vary in severity and cause significant pain. OnabotulinumtoxinA is an approved treatment for CD. This study assessed health-related quality of life (HRQoL) in patients with CD who received multiple onabotulinumtoxinA treatments. Methods: This prospective, observational standard-of-care study was conducted at multiple neurology centers in Québec, Canada. Patients reported the health impact of CD using the Cervical Dystonia Impact Profile (CDIP)-58, before and after up to eight onabotulinumtoxinA treatments. Other measures included the Cervical Dystonia Severity Rating Scale by physician, employment status using the Work Productivity Questionnaire and pain using the Pain Numeric Rating Scale (PNRS). Adverse events (AEs) were recorded. Results: Sixty-two patients were enrolled (safety population, n = 61; modified efficacy population, n = 58). Participants were mostly females who were employed; most (79.3%) had torticollis. In all, 21/62 patients (33.9%) discontinued the study. At the final visit, there was a statistically significant (p < 0.001) improvement in all eight CDIP-58 subscales, particularly head and neck symptoms (−31.0) and psychosocial functioning (−28.2). Employment increased from baseline (55%) to the end of the study (64%), and there was improvement in work productivity. There was a significant (p < 0.0001) reduction in pain measured by the PNRS, from −0.5 post-treatment 1 to −2.4 at end of study. AEs (neck pain, muscular weakness, dysphagia, nausea) were consistent with onabotulinumtoxinA use. Conclusion: These real-world data indicate that after repeated, long-term use, onabotulinumtoxinA continues to be a safe and effective treatment for CD, improving HRQoL and work productivity.

Abstract
Purpose of Review Migraine is a common disorder which in many cases can be adequately treated with medications. However, there are some patients who may either not respond to medications or have contraindications to their use. In this review, we will evaluate the available literature on the interventional procedures available to treat patients with episodic migraine. We will review the technical details of performing the procedures, the potential mechanisms of action, and available data on their effectiveness. Recent Findings Recent studies conducted on the subject of interventional procedures including peripheral nerve blocks and onabotulinumtoxinA indicate that some patients with episodic migraine may find benefit from such procedures. Summary In patients with episodic migraine whom traditional treatments have not been effective or are contraindicated, interventional procedures may offer an opportunity to provide additional treatment options.

OBJECTIVE To report the pregnancy outcomes on patients with chronic migraine exposed to onabotulinumtoxinA from Hull Headache Clinic. BACKGROUND Migraines are common in women of reproductive age and those with chronic migraine have a major impact on their activities of daily living and health-related quality of life. Apart from low dose amitriptyline and beta-blockers all other prophylactic agents have proven teratogenic effects. OnabotulinumtoxinA is approved as preventive treatment for adult patients with chronic migraine, although its impact on pregnancy is unknown. METHODS We prospectively collected data for efficacy and safety on all patients treated with onabotulinumtoxinA at the Hull Headache Clinic. The toxin is administered as per PREEMPT paradigm. Female patients of reproductive age group receiving onabotulinumtoxinA are given advice on contraception and the unknown impact of the toxin on pregnancy. They are asked to report pregnancy when they are appraised on the risk/benefit of treatment continuation. All patients are consented for access to their medical records and pregnancy outcome and those who wished to continue are asked to sign a disclaimer. Pregnancy outcome data was collected on all patients for the mode of delivery, birth weight and congenital malformation and any other unexpected outcomes. RESULTS Over 9 years period 45 patients reported pregnancy while receiving onabotulinumtoxinA. All patients had received onabotulinumtoxinA within 3 months prior to the date of conception. 32 patients wished to continue treatment during pregnancy while the remaining 13 stopped treatment. Apart from 1 miscarriage in the treatment group, all patients had full term healthy babies of normal birth weight and no congenital malformations. CONCLUSION We report our experience of 45 patients exposed to onabotulinumtoxinA during pregnancy. Although the numbers are small, there was no impact of the toxin found on the pregnancy outcomes.

Patel AT, Ward AB, Geis C, Jost WH, Liu C, Dimitrova R. Impact of early intervention with onabotulinumtoxinA treatment in adult patients with post-stroke lower limb spasticity: results from the double-blind, placebo-controlled, phase 3 REFLEX study. J Neural Transm (Vienna) 2020; 127:1619-1629. [PMID: 33106968 PMCID: PMC7666298 DOI: 10.1007/s00702-020-02251-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2020] [Accepted: 08/31/2020] [Indexed: 11/24/2022]
Abstract
The aim of this study in patients with post-stroke lower limb spasticity (PSLLS) was to evaluate the relationship between time of onabotulinumtoxinA treatment relative to stroke and efficacy outcomes. This was a phase 3, international, multicenter, randomized, 12-week, double-blind study, followed by a repeated treatment, open-label extension. Patients were aged 18–85 years with PSLLS (Modified Ashworth Scale [MAS] ≥ 3) of the ankle with the most recent stroke occurring ≥ 3 months before screening. Patients (double-blind phase) were randomized (n = 468) to onabotulinumtoxinA 300–400 U (300 U, mandatory ankle muscles (gastrocnemius, soleus, tibialis posterior); and ≤ 100 U, optional lower limb muscles (flexor digitorum longus, flexor hallucis longus, flexor digitorum brevis, extensor hallucis, and rectus femoris]) or placebo. Primary endpoint: MAS change from baseline (average score of weeks 4 and 6). Secondary endpoints: physician-assessed Clinical Global Impression of Change (CGI) average score of weeks 4 and 6 and physician-assessed Goal Attainment Scale (GAS; active and passive, weeks 8 and 12). When stratified by time since stroke (≤ 24 months, n = 153; > 24 months, n = 315, post hoc), patients treated ≤ 24 months post-stroke experienced greater improvements from baseline versus placebo in MAS (− 0.31 vs − 0.17), CGI (0.49 vs 0.12), and passive GAS scores (week 12, 0.37 vs 0.26). A ≥ − 1-point improvement in active (week 12; p = 0.04) and passive (week 8; p = 0.02) GAS scores versus placebo was achieved by more patients treated ≤ 24 months post-stroke; in patients treated > 24 months post-stroke, improvements were only observed in active scores (week 8; p = 0.04). OnabotulinumtoxinA 300–400 U was well tolerated, with no new safety findings.

Impulse control disorders in chronic migraine with medication overuse after onabotulinumtoxinA: A single-center prospective cohort study. J Clin Neurosci 2020; 80:152-155. [PMID: 33099338 DOI: 10.1016/j.jocn.2020.07.075] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2020] [Revised: 07/16/2020] [Accepted: 07/31/2020] [Indexed: 01/17/2023]
Abstract
Chronic migraine (CM) with medication overuse headache (MOH) is one of the most common and disabling chronic headache disorders associated with both frequencies of use of medication and behavioral alterations, including psychopathology and psychological drug dependence. Several previous studies on large patient samples have demonstrated the efficacy of Onabotulinum toxin A (OnabotA) on physical symptomatology treatment of headache, but effects on behavioral alterations remain still debate. Our study investigated the effects of OnabotA on psychiatric comorbidities and on quality of life of patients with CM and MOH that failed on traditional therapies. OnabotA was injected, according to the PREEMPT paradigm, 40 patients with CM and MOH and data on headache-related impairment, before and after the OnabotA injections were collected from the patient's headache diaries. Data on depressive, anxiety symptomatology and impulse control disorders also were collected by means of self-report scales and a semi-structured interview. After six months, patients with CM and MOH showed a significant decrease in monthly headache attacks (from 19.3 ± 5.9 to 11.8 ± 8.5, p = 0.003), monthly headache days (from 23 ± 8.9 to 11.1 ± 6.2, p = 0.001), numbers of analgesics used per month (from 18.2 ± 6.3 to 8.5 ± 4.7, p < 0.0001). The anxiety symptomatology (p ≤ 0.003) and impulse control disorders (from 30% to 10%), but not depressive symptomatology (p = 0.81), were significantly reduced from throughout the study. The treatment with OnabotA proved beneficial effects on anxiety symptomatology and on impulse control disorders in our clinical practice with CM and MOH and further studies should shed light in larger patient samples on long-term behavioural effects.

Abstract
INTRODUCTION Little is known about long-term efficacy and tolerance of intra-detrusor injections of abobotulinumtoxinA for management of idiopathic overactive bladder (OAB). We report long-term efficacy and compliance of abobotulinumtoxinA in patients treated for OAB. METHODS All patients treated with abotulinumtoxinA for OAB in a tertiary reference centre between 2005 and 2012 were included in a retrospective analysis. Patients received 150, 250 or 500 U of abotulinumtoxinA as first injection. The primary endpoint was the discontinuation rate at 5 years. Other outcomes of interest were: rate of failure, reasons for discontinuation and subsequent treatment elected in those who did not persist with abobotulinumtoxinA. RESULTS Fifty-nine patients (50 women and 9 men) were included. Forty-one patients (69.4%) received 250 U of abobotulinumtoxinA as first injection. Thirteen patients (22%) received 500 U and 5 (8.4%) received 150 U of BoNT-A. Median follow-up was 83.6 months [0.3-183.6]. Median number of injections per patient was 2 [1-15] and median reinjection interval was 10.7 [3-86.4] months. The estimated 5-year discontinuation-free survival rate was 23.4%. Fourteen patients (23.7%) experienced persistent improvement of symptoms and 12 patients (20.3%) stopped the injections because of tolerability issues. Main cause of discontinuation was primary failure, which occurred in 21 patients (35.5%). CONCLUSION Overall, 59.3% of patients were successfully treated with first abobotulinumtoxinA injection. Although the estimated 5-year discontinuation-free survival rate is low, abobotulinumtoxinA could be considered as an alternative off-labelled in patients not responders to onabotulinumtoxinA after failure of other conservative measures.

Abstract
OBJECTIVE Long-term real-life studies have supported a cumulative effect of OnabotulinumtoxinA (OnabotA) for the prophylactic treatment of chronic migraine (CM) during consecutive cycles, and individual adaptations have been described to improve clinical response. METHODS This was a cohort longitudinal retrospective study of consecutive adult patients from the Headache Unit of the Hospital Clínico Universitario de Valladolid and the Hospital Universitario de La Princesa (Madrid) on OnabotA treatment for chronic migraine from May 2012 to December 2017. All patients were followed for 24 weeks. Full-length response to OnabotA was defined as ≥50% reduction in headache days for at least 12 weeks, and wearing off response was defined as a clinical response but with duration shorter than 10 weeks. We have analyzed the incidence and clinical predictors of this wearing off response. RESULTS A total of 193 patients were included, of whom 91 (47.1%) were considered full-length responders and 45 (23.3%) wearing off responders. No statistically significant clinical predictors (including demographic variables and baseline headache characteristics) of full-length response or wearing off response were detected in our study. An increase in dose during the second treatment cycle was attempted in 68.9% of the wearing off patients, achieving a longer duration of response of up to 12 weeks in 74.2%. CONCLUSIONS Wearing off response to OnabotA during the first treatment cycle is not uncommon in patients with CM. Increasing the dose in subsequent cycles could improve clinical response, but further multicenter long-term studies are needed to establish predictors and solutions to this problem.

Wear-Off of OnabotulinumtoxinA Effect Over the Treatment Interval in Chronic Migraine: A Retrospective Chart Review With Analysis of Headache Diaries. Headache 2020; 60:1673-1682. [PMID: 32797631 DOI: 10.1111/head.13925] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2020] [Revised: 06/26/2020] [Accepted: 07/13/2020] [Indexed: 12/18/2022]
Abstract
OBJECTIVE To quantify wear-off of the response to OnabotulinumtoxinA (OnabotA) treatment over the treatment cycle in chronic migraine at group and individual level. BACKGROUND OnabotA administered quarterly is an effective treatment for chronic migraine. However, some patients report that headache recurs before the scheduled follow-up injection. METHODS In this retrospective chart review performed in 6 university outpatient centers or private practices specialized in headache treatment, 112 patients with a ≥30% response to OnabotA who completed headache diaries over 13 weeks after OnabotA treatment were included (age [mean ± SD] 45 ± 12 years, 82% female, headache days/month at baseline 24 ± 6). RESULTS Compared to weeks 5 to 8 after injection, headache days/week increased significantly in weeks 12 (+0.52 ± 1.96, 95% CI [0.15, 0.88], P < .009) and 13 (+1.15 ± 1.95, CI[0.79, 1.52], P < .001), demonstrating significant wear-off of the OnabotA effect. Similarly, acute medication days/week significantly increased in weeks 12 (0.38±1.67, CI [0.06, 0.69], P ≤ .027) and 13 (+0.83 ± 1.76, CI [0.49, 1.16], P < .001). At an individual level, 57 patients (51%) showed ≥30% wear-off by weeks 12 and 13, and 28 patients (25%) showed ≥30% wear-off already by weeks 10 and 11. Age, gender, OnabotA dose or cycle number, or headache center did not predict individual wear-off. CONCLUSIONS These data show that in clinical practice, on average the response of chronic migraine patients to OnabotA injection shows a clinically significant wear-off from week 12 after treatment. About 25% of the patients experience wear-off even by weeks 10 and 11. It must be noted that wear-off detected in a real-world study on OnabotA responders can be due to wear-off of a pharmacological OnabotA effect or a placebo effect, or to regression to the mean effects. This wear-off phenomenon may negatively affect quality of life of chronic migraine patients under OnabotA treatment. The best way to counteract wear-off remains to be determined.

Abstract
BACKGROUND This paper provides a critical review of the decision-making process of the Ontario Ministry of Health and Long-Term Care (MOHLTC) regarding which migraine treatment drugs will be covered under the Ontario Drug Benefit Formulary (ODB). MAIN TEXT Under MOHLTC policy, triptans and OnabotulinumtoxinA are available to patients only through the Exceptional Access Program (EAP). This policy, and justifications for it, are examined with reference to clinical guidelines, patient experiences, and health policy literature. The contexts and consequences of compromised access are outlined. Improvements in access to these treatments are suggested by highlighting how a country with similar healthcare infrastructure - Australia - employs policies that more adequately meet the needs of migraine patients as they secure treatments. CONCLUSIONS Despite clinically significant gains in the discovery of safe and effective migraine-specific treatments the ODB thus far has failed to align its practice with current clinical recommendations. This forces patients to rely heavily on medication that, while still effective for some, is potentially suboptimal. This review concludes it is prudent, at minimum, to follow clinical recommendations that advocate for the removal of triptans from EAP and recategorize them as Limited Use drugs. Ideally, moving them to a general benefit would further remove the barriers experienced by patients attempting to access this treatment.

OnabotulinumtoxinA is a well tolerated and effective treatment for refractory overactive bladder in real-world practice. Int Urogynecol J 2020; 32:65-74.

Abstract
Introduction and hypothesis In randomized clinical trials onabotulinumtoxinA was demonstrated to be an effective and well-tolerated treatment for overactive bladder (OAB) with urinary incontinence (UI). However, data reporting onabotulinumtoxinA use in everyday clinical practice are limited. Here, we present the results from a large, first-of-its-kind real-world study in patients with OAB. Methods This was a prospective, observational, multinational study (GRACE; ClinicalTrials.gov, NCT02161159) performed in four European countries. Patients (N = 504) aged ≥ 18 years with OAB inadequately managed with ≥ 1 anticholinergic received onabotulinumtoxinA per their physician’s normal clinical practice. Results Physicians primarily used rigid cystoscopes for onabotulinumtoxinA injection; anesthesia/analgesia was utilized during most treatment procedures. Significant reductions in UI episodes/day from baseline to weeks 1 and 12 were observed as well as in micturition, urgency, and nocturia episodes/day. These improvements in urinary symptoms corresponded to higher scores on the treatment benefit scale at week 12. The use of other OAB medications dropped from baseline to weeks 1 and 12 and was sustained to week 52, which paralleled a reduction in the number of incontinence products used during that time frame. Adverse reactions were reported in 2.6% of patients throughout the study. Conclusions In this real-world study, significant improvements in urinary symptoms were seen following onabotulinumtoxinA treatment as early as week 1 and sustained to at least week 12. This was accompanied by a reduced reliance upon incontinence products and reduction in concomitant OAB medication use. OnabotulinumtoxinA was well tolerated with no new safety signals.

Abstract
INTRODUCTION AND HYPOTHESIS This systematic review and meta-analysis aim to evaluate the outcomes between SNM and BTX in the treatment of refractory OAB. METHODS PubMed, Embase, and CENTRAL were comprehensively searched from their inception to December 2019. Randomized and nonrandomized controlled trials evaluating OAB patients who underwent SNM and BTX were included. Data extraction and quality assessment were conducted by two independent reviewers. The outcomes, side effects, and cost-effectiveness values of both procedures were compared in meta-analysis. RESULTS This review involved six articles (2629 patients). Specifically, three articles were based on the same trial, and the other studies were retrospective cohort studies. No significant difference was found in successful treatment between BTX and SNM at 6 months after procedures [risk ratio (RR) = 0.93, 95% confidence interval (CI) 0.63-1.39]. BTX exhibited a significantly higher total adverse event rate than SNM through 6 months (RR = 1.55, 95% CI 1.28-1.88). Patients suffered more urinary tract infection (UTI) risk under BTX injection at the early stage (RR = 1.58, 95% CI 1.10-2.25); however, the difference in UTI events was not significant between the two groups (RR = 1.13, 95% CI 1.10-2.25) during the period of 7-12 months postoperatively. Obviously, the short-term cost (1-2 years) of BTX was significantly lower than that of the SNM procedure. CONCLUSIONS Both treatments were effective; however, because of the high complication rate of BTX, it may not be a better way to treat refractory OAB than SNM, although BTX is more cost-effective for short-term treatment at present.

Abstract
Blepharospasm and oromandibular dystonia are focal dystonias characterized by involuntary and often patterned, repetitive muscle contractions. There is a long history of medical and surgical therapies, with the current first-line therapy, botulinum neurotoxin (BoNT), becoming standard of care in 1989. This comprehensive review utilized MEDLINE and PubMed and provides an overview of the history of these focal dystonias, BoNT, and the use of toxin to treat them. We present the levels of clinical evidence for each toxin for both, focal dystonias and offer guidance for muscle and site selection as well as dosing.

Abstract
OBJECTIVE To identify clinical predictors of excellent response to OnabotulinumtoxinA in patients with chronic migraine (CM) at 6 and 12 months of follow-up. BACKGROUND Clinical predictors of response to OnabotulinumtoxinA are scarce and have not been clearly reproduced and analyzed in detail. So far, predictors of response to OnabotulinumtoxinA assess response in general or good response, but not an excellent response. METHODS Cohort study of patients attended in a specialized Headache Clinic in treatment with OnabotulinumtoxinA were classified according to their improvement in frequency: no-response (<25%) and excellent response (≥75%). A comparative analysis was carried out at 6 and 12 months identifying clinical predictors of excellent response to OnabotulinumtoxinA at each timepoint. RESULTS Data were collected from 221 patients. After 6 and also 12 months, we observed a statistically significant mean reduction in frequency and analgesic intake. At month 6, independent variables associated with excellent response (OR[95%CI]) were daily headache frequency (0.32[0.14-0.74]; P = .005), medication overuse (MO) (2.28[1.19-4.37]; P = .013), and a higher ratio of migraine days/month (MDM) (1.20[1.10-1.45]; P = .018) at baseline. At month 12, independent predictors of excellent response were patients with less than 30 years of migraine evolution (0.43[0.23-0.82]; P = .011), presence of anxiety (0.44[0.23-0.85]; P = .018), and aura (0.48[0.25-0.92]; P = .037). Excellent responders showed a higher improvement rate in pain intensity at 6 and 12 months. CONCLUSIONS Patients with daily frequency and MO show a clinical improvement in short-term. Patients with comorbidities who start treatment earlier in the course of the disease need a longer duration of treatment. The profile of response to treatment with OnabotulinumtoxinA determines its minimum treatment duration and the timepoint of a meaningful response.

Comparing the Efficacy of OnabotulinumtoxinA, Sacral Neuromodulation, and Peripheral Tibial Nerve Stimulation as Third Line Treatment for the Management of Overactive Bladder Symptoms in Adults: Systematic Review and Network Meta-Analysis. Toxins (Basel) 2020; 12:toxins12020128.

Abstract
The American Urological Association guidelines for the management of non-neurogenic overactive bladder (OAB) recommend the use of OnabotulinumtoxinA, sacral neuromodulation (SNM), and peripheral tibial nerve stimulation (PTNS) as third line treatment options with no treatment hierarchy. The current study used network meta-analysis to compare the efficacy of these three modalities for managing adult OAB syndrome. We performed systematic literature searches of several databases from January 1995 to September 2019 with language restricted to English. All randomized control trials that compared any dose of OnabotulinumtoxinA, SNM, and PTNS with each other or a placebo for the management of adult OAB were included in the study. Overall, 17 randomized control trials, with a follow up of 3–6 months in the predominance of trials (range 1.5–24 months), were included for analysis. For each trial outcome, the results were reported as an average number of episodes of the outcome at baseline. Compared with the placebo, all three treatments were more efficacious for the selected outcome parameters. OnabotulinumtoxinA resulted in a higher number of complications, including urinary tract infection and urine retention. Compared with OnabotulinumtoxinA and PTNS, SNM resulted in the greatest reduction in urinary incontinence episodes and voiding frequency. However, comparison of their long-term efficacy was lacking. Further studies on the long-term effectiveness of the three treatment options, with standardized questionnaires and parameters are warranted.

Abstract
Introduction OnabotulinumtoxinA (BoNT-A) was proved effective and safe in chronic migraine (CM) prevention by the Phase III Research Evaluating Migraine Prophylaxis (PREEMPT) and Phase IV Chronic migraine OnabotulinuMtoxinA Prolonged Efficacy open-Label (COMPEL) trials over 1 and 2 years of treatment, respectively. Real-life studies highlighted BoNT-A sustained benefits up to 3 years of administration. Aim of this retrospective real-life study was observing within a 4-year timeframe the progress of a consecutive series of CM patients treated with BoNT-A and evaluating whether long-term quarterly treatment (up to 16 cycles) confirms the outcomes of previous studies over shorter periods of therapy. Methods One hundred nine chronic migraineurs were quarterly treated with BoNT-A according to the PREEMPT paradigm. Headache days and hours, analgesics intake and latency time together with disability were analysed at baseline, thereafter bi-annually up to 48 months. Patient responsiveness (improvement in monthly headache days and hours versus baseline) was computed at each study timepoint. Results A significant overall decrease from baseline to the 48-month assessment (p < 0.001) was evidenced for the mean number of monthly headache days and hours, analgesics intake and latency time. Severe disability cases significantly decreased at 6 months (p < 0.001), and a progressive shift towards lower degrees of disability was observed at each subsequent timepoint. A gradual percentage increase of responsive cases was observed as treatment was repeated over time. Transitory neck pain was reported in 6 cases. Conclusions This study appears to reconfirm the benefits of long-lasting CM prevention with BoNT-A, thus supporting quarterly treatment with BoNT-A over several year.
