Cerebrolysin and Recovery After Stroke (CARS): A Randomized, Placebo-Controlled, Double-Blind, Multicenter Trial.

ABSTRACT: The aim of this trial was to investigate whether stroke patients who receive Cerebrolysin show improved motor function in the upper extremities at day 90 compared with patients who receive a placebo.This study was a prospective, randomized, double-blind, placebo-controlled, multicenter, parallel-group study. Patients were treated with Cerebrolysin (30 mL/d) or a placebo (saline) once daily for 21 days, beginning at 24 to 72 hours after stroke onset. The patients also participated in a standardized rehabilitation program for 21 days that was initiated within 72 hours after stroke onset. The primary end point was the Action Research Arm Test score on day 90.The nonparametric effect size on the Action Research Arm Test score on day 90 indicated a large superiority of Cerebrolysin compared with the placebo (Mann-Whitney estimator, 0.71; 95% confidence interval, 0.63-0.79; P<0.0001). The multivariate effect size on global status, as assessed using 12 different outcome scales, indicated a small-to-medium superiority of Cerebrolysin (Mann-Whitney estimator, 0.62; 95% confidence interval, 0.58-0.65; P<0.0001). The rate of premature discontinuation was <5% (3.8%). Cerebrolysin was safe and well tolerated.Cerebrolysin had a beneficial effect on function and global outcome in early rehabilitation patients after stroke. Its safety was comparable with that of the placebo, suggesting a favorable benefit/risk ratio. Because this study was exploratory and had a relatively small sample size, the results should be confirmed in a large-scale, randomized clinical trial.URL: http://www.clinicaltrialsregister.eu.

Project description:BackgroundSpontaneous, nontraumatic intracerebral hemorrhage (ICH) is a subtype of stroke that causes a great amount of disability and economic and social burden. This is particularly true in developing countries where it accounts for between 20% and 50% of all strokes. Pharmacological and surgical interventions have been attempted to reduce the mortality and disability caused by ICH, with unsuccessful results. Recently, the use of fluoxetine in addition to physical rehabilitation has been proven useful to improve motor recovery following cerebral infarct. The purpose of this study is to test whether a 3-month treatment with fluoxetine enhances motor recovery in nondepressed patients with acute intracerebral hemorrhage.Methods/designOur study is a randomized, double-blind, placebo-controlled, multicenter clinical trial. We will recruit 86 patients with intracerebral hemorrhage of both sexes, aged >18 years, from four Mexican hospitals. The patients will receive either 20 mg of fluoxetine or a placebo once daily for 90 days. The primary outcome is the mean change in the Fugl-Meyer Motor Scale score between inclusion (day 0) and day 90. The secondary outcomes will be changes in the Barthel Index, the Modified Rankin scale and the National Institutes of Health stroke scale. The outcomes will be measured at day 42 ± 7 days and at day 90, for a total of four visits with each subject (at screening and at 0, 42 and 90 days).DiscussionCurrent guidelines recommend early supported hospital discharge and home-based rehabilitation programs as the only cost-effective intervention to aid the recovery of patients with intracerebral hemorrhage. Nevertheless, such interventions are dependent on available resources and funding, which make them very difficult to implement in developing countries. We believe that the identification of a helpful pharmacological intervention to aid the motor recovery of these patients will constitute a breakthrough that will have a major impact in reducing the burden of disease caused by this subtype of stroke worldwide, especially in the developing world.Trial registrationCurrent Controlled Trials NCT01737541.

Project description:Objective. Ischemic stroke is a serious medical condition with limited therapeutic options. The evaluation of the therapeutic potential of novel pharmacological interventions is carried-out in Phase II trials. The study design, primarily intended to evaluate efficacy and safety, is a balance between utilizing as few patients as possible to minimize safety risk and enrolling sufficient patients to detect unambiguous efficacy signals. We sought to determine whether post-stroke recovery outcomes based on behavioral measures of cognitive and motor impairment yielded additional information beyond that of clinician-based methods. Design. This was a multicenter, multinational, randomized, parallel group, controlled versus placebo, efficacy, and safety study of PF-03049423 for treatment of acute ischemic stroke. Settings and participants. Our study subjects were acute ischemic stroke inpatients. Measurements. Outcome measures were derived from rating scales (Modified Rankin Scale, Barthel Index, and National Institutes of Health Stroke Scale) and behavioral tests (Box and Blocks Test, Hand Grip Strength Test, 10-Meter Walk Test, Repeatable Battery Assessment of Neuropsychological Status Naming and Coding Subtests, Line Cancellation Test, and Recognition Memory Test). Assessments were performed at Days 7, 14, 30, 60, and 90. Post-hoc analyses of correlations among the outcome measures at each measurement time point on a cohort of 137 subjects were conducted. Results. Results support the validity of measures from Box and Blocks Test, Hand Grip Strength Test, 10-Meter Walk Test, and Repeatable Battery Assessment of Neuropsychological Status Coding Subtests to monitor post-stroke recovery in clinical trial settings. Notably, the Recognition Memory Test did not show a correlation with the Modified Rankin Scale, and, in fact, did not show improvement over time. Conclusion. The behavioral measures of cognitive and motor functions included in this study may extend the evaluation of the therapeutic potential of new treatments for stroke recovery. The lack of correlation between Recognition Memory Test and the traditional efficacy endpoints, at least in part due to absence of any improvement in recognition memory, suggests that there may be cognitive elements not detected by the Modified Rankin Scale. This is clinically relevant and memory improvement has potential as an endpoint in future trials aiming to improve certain aspects of cognition.

Project description:BackgroundIschemic stroke is a leading cause of morbidity and mortality. Thrombolytic therapy improves disability and survival rates; however, to be effective, it must be given within 4.5 h of onset. Moreover, thrombolytic therapy is frequently contraindicated. Therefore, alternative therapeutic options are required. In China, cinepazide maleate injection has been shown to improve the cerebral collateral circulation and further reduce disability in stroke patients; however, very few studies investigating this therapy have been conducted to date. Therefore, this study aimed to further confirm the efficacy and safety of cinepazide maleate injection in patients with acute ischemic stroke.MethodsPatients with acute ischemic stroke were administered an intravenous infusion of 320 mg cinepazide maleate or placebo once daily for 14 days. All patients were also administered basic therapy (citicoline sodium). The primary efficacy endpoint was the proportion of patients with a modified Rankin scale (mRS) ≤2 on day 90. Secondary efficacy endpoints included Barthel Index ≥95. Safety was evaluated by recording all adverse events (AEs), monitoring laboratory parameters and vital signs, and electrocardiogram.ResultsIn total, 937 patients with an acute ischemic stroke were included, with a mean (standard deviation, SD) National Institutes of Health Stroke Scale score of 8.8 (2.4) and a mean (SD) stroke onset of 30.9 (11.4) hours prior. Following treatment for 90 days, the proportion of patients with an mRS score ≤ 2 was significantly higher in the cinepazide maleate group than in the control group (60.9% vs. 50.1%; p = 0.0004). Moreover, the proportion of patients with a Barthel Index of ≥95 on day 90 was also significantly higher in the cinepazide maleate group than in the control group (53.4% vs. 46.7%; p = 0.0230). There were no statistically significant differences in safety parameters between the cinepazide maleate and control groups.ConclusionsThe results of this study show that cinepazide maleate injection is superior to placebo in improving neurological function and activities of daily living, reducing disability, and promoting functional recovery in patients with acute ischemic stroke. Cinepazide maleate injection was safe and well tolerated with no unexpected AEs reported.Trial registrationChinese Clinical Trial Registry CTR20160292 and ChiCTR1900023827 .

Project description:OBJECTIVE:To assess the efficacy and safety of a remote electrical neuromodulation (REN) device for the acute treatment of migraine. BACKGROUND:There is a significant unmet need for novel effective well-tolerated acute migraine treatments. REN is a novel acute migraine treatment that stimulates upper arm peripheral nerves to induce conditioned pain modulation - an endogenous analgesic mechanism in which conditioning stimulation inhibits pain in remote body regions. A recent pilot study showed that REN can significantly reduce headache. We have conducted a randomized, double-blind, sham-controlled study to further evaluate the efficacy and safety of REN for the acute treatment of migraine. METHODS:This was a randomized, double-blind, sham-controlled, multicenter study conducted at 7 sites in the United States and 5 sites in Israel. Two hundred and fifty-two adults meeting the International Classification of Headache Disorders criteria for migraine with 2-8 migraine headaches per month were randomized in a 1:1 ratio to active or sham stimulation. A smartphone-controlled wireless device was applied for 30-45 minutes on the upper arm within 1 hour of attack onset; electrical stimulation was at a perceptible but non-painful intensity level. Migraine pain levels were recorded at baseline, 2, and 48 hours post-treatment. Most bothersome symptoms (MBS) were also recorded. The primary efficacy endpoint was the proportion of participants achieving pain relief at 2 hours post-treatment (improvement from severe or moderate pain to mild or none, or from mild pain to none). Relief of MBS and pain-free at 2 hours were key secondary endpoints. RESULTS:Active stimulation was more effective than sham stimulation in achieving pain relief (66.7% [66/99] vs 38.8% [40/103]; therapeutic gain of 27.9% [CI95% , 15.6-40.2]; P < .0001), pain-free (37.4% vs 18.4%, P = .003), and MBS relief (46.3% vs 22.2%, P = .0008) at 2 hours post-treatment. The pain relief and pain-free superiority of the active treatment was sustained 48 hours post-treatment. The incidence of device-related adverse events was low and similar between treatment groups (4.8% [6/126] vs 2.4% [3/126], P = .499). CONCLUSIONS:REN provides superior clinically meaningful relief of migraine pain and MBS compared to placebo, offering a safe and effective non-pharmacological alternative for acute migraine treatment.
