Abstract Resveratrol is a polyphenol that has been well studied and has demonstrated anti-viral and anti-inflammatory properties that might mitigate the effects of COVID-19. Outpatients (N=105) were recruited from central Ohio in late 2020. Participants were randomly assigned to receive placebo or resveratrol. Both groups received a single dose of Vitamin D3 which was used as an adjunct. The primary outcome measure was hospitalization within 21 days of symptom onset; secondary measures were ER visits, incidence of pneumonia and pulmonary embolism. Five patients chose not to participate after randomization. Twenty-one day outcome was determined of all one hundred participants (mean [SD] age 55.6 [8.8] years; 61% female) (or their surrogates). There were no clinically significant adverse events attributed to resveratrol. Outpatients in this phase 2 study treated with resveratrol had a lower incidence compared to placebo of: hospitalization (2% vs. 6%, RR 0.33, 95% CI 0.04-3.10), COVID-related ER visits (8% vs. 14%, RR 0.57, 95% CI 0.18-1.83), and pneumonia (8% vs. 16%, RR 0.5, 95% CI 0.16-1.55). One patient (2%) in each group developed pulmonary embolism (RR 1.00, 95% CI: 0.06-15.55). This underpowered study was limited by small sample size and low incidence of primary adverse events. A larger trial could determine efficacy.TRIAL REGISTRATIONS: ClinicalTrials.gov NCT04400890 26/05/2020; FDA IND #150033 05/05/2020

Abstract Background Tofacitinib is an oral, small molecule JAK inhibitor for the treatment of ulcerative colitis (UC). RIVETING (NCT03281304) is an ongoing, double-blind, randomised, parallel-group study designed to evaluate the efficacy and safety of dose reduction to tofacitinib 5 mg twice daily (BID) vs remaining on 10 mg BID in patients (pts) with UC in stable remission on tofacitinib 10 mg BID maintenance therapy. Eligible pts had received tofacitinib 10 mg BID for ≥2 consecutive years in an open-label, long-term extension study (NCT01470612), and had been in stable remission for ≥6 months (M) and corticosteroid-free for ≥4 weeks prior to enrolment.1 We aimed to evaluate the association between the duration of remission prior to enrolment into RIVETING and the efficacy of tofacitinib 5 and 10 mg BID. Methods Pts who were in partial Mayo score (PMS) remission (a PMS of ≤2 with no individual subscore >1, and a rectal bleeding subscore of 0) at RIVETING baseline were included in this analysis. Pts were randomised to dose-reduce to tofacitinib 5 mg BID or remain on 10 mg BID. We evaluated efficacy endpoints at Month 6 in RIVETING, stratified by duration of PMS remission (0–12, 12–24, 24–36, 36–48, >48 M) at RIVETING baseline. Results At RIVETING baseline, 139 of 140 pts were in PMS remission: 69 pts dose-reduced to tofacitinib 5 mg BID and 70 pts remained on tofacitinib 10 mg BID. In both treatment groups, compared with pts with <24M of PMS remission, baseline modified Mayo and total Mayo scores were numerically lower in pts with a PMS remission duration of >24M; these pts also generally had a numerically lower change from baseline modified Mayo and total Mayo scores at Month 6 (Table). At Month 6, following dose reduction to tofacitinib 5 mg BID, PMS remission was maintained in 66.7%, 60.0%, 82.4%, 75.0% and 90.0% of pts with baseline PMS remission durations of 0–12M, 12–24M, 24–36M, 36–48M and >48M, respectively. Corresponding values for pts who continued to receive tofacitinib 10 mg BID were 80.0%, 88.9%, 91.7%, 100.0% and 100.0%. At Month 6, the proportion of pts achieving modified Mayo remission, remission and modified PMS remission was generally higher in pts with baseline PMS remission of >24M vs pts with PMS remission of <24M across treatment groups (Table). Conclusion Following dose reduction from tofacitinib 10 to 5 mg BID, rates of modified Mayo remission, remission and PMS remission were numerically higher in pts with a PMS remission duration of >24M vs pts with <24M of PMS remission duration. The same trend was observed in pts who continued to receive tofacitinib 10 mg BID. These analyses are post hoc and limited by the small sample size. Reference

ABSTRACTST-246 is being evaluated as a treatment for pathogenic orthopoxvirus infections in humans. To this end, a phase 2, double-blind, randomized, placebo-controlled, multicenter trial was conducted to assess the safety, tolerability, and pharmacokinetics (PK) of ST-246 when administered as a single daily oral dose (400 mg or 600 mg) for 14 days in fed adult volunteers. ST-246 was safe and well tolerated, with no deaths or serious adverse events reported during the study. There was a low incidence of treatment-emergent adverse events (TEAEs), the most common of which were mild nausea and headache. There were no clinically significant results from laboratory assessments, vital sign measurements, physical examinations, or electrocardiograms. The PK and dose proportionality of ST-246 were determined. The PK analysis showed that steady state was achieved by day 5 for the ST-246 400-mg treatment group and by day 6 for the 600-mg group. The dose proportionality analysis showed that the 400- and 600-mg ratio of dose-normalized peak drug concentration in plasma (Cmax) and relative exposure for each dosing interval (AUCτ) ranged from 80% to 85%. However, the 90% confidence intervals did not include 1.0, so dose proportionality could not be concluded. Overall, ST-246 was shown to be safe, and the PK was predictable. These results support further testing of ST-246 in a multicenter pivotal clinical safety study for licensure application.

Safety monitoring and successful blinding are important features of randomized, blinded clinical trials. We report chamber- and protocol-related adverse events (AEs) for participants enrolled in two randomized, double-blind clinical trials of hyperbaric oxygen (HBO2) for persistent post-concussive symptoms clinicaltrials.gov identifiers NCT01306968, HOPPS, and NCT01611194, BIMA), as well as the success of maintaining the blind with a low-pressure sham control arm. In both studies, participants were randomized to receive HBO2 (1.5 atmospheres absolute, >99% oxygen) or sham chamber sessions (1.2 atmospheres absolute, room air). In 143 participants undergoing 4,245 chamber sessions, chamber-related adverse events were rare (1.1% in the HOPPS study, 2.2% in the BIMA study). Minor, non-limiting barotrauma was the most frequently reported. Rarely, some participants experienced headache with chamber sessions. No serious adverse events were associated with chamber sessions. An allocation questionnaire completed after intervention revealed that the sham control arm adequately protected the blind in both trials. Participants based allocation assumptions on symptom improvement or lack of symptom improvement and could not discern intervention arm by pressure, smell, taste, or gas flow.

IntroductionUp to 50% of patients with OCD have failed to respond in SSRI trials, so looking for pharmacological alternatives in treatment of obsessive compulsive disorder (OCD) seems necessary.ObjectivesSurveying duloxetine augmentation in treatment of resistant OCD.AimsStudy the effects of serotonin-norepinephrine enhancers for treatment of OCD.MethodsThis augmentation trial was designed as an 8-week randomized controlled, double blind study. Forty-six patients suffering from OCD who had failed to respond to at least 12 weeks of treatment with a selective serotonin reuptake inhibitor (fluoxetine, citalopram or fluvoxamine) were randomly allocated to receive duloxetine or sertraline plus their current anti OCD treatment. Yale-Brown Obsessive Compulsive Scale (Y-BOCS) was the primary outcome measure.ResultsForty-six patients (24 of 30 in duloxetine group and 22 of 27 in sertraline group) completed the trial. Both groups showed improvement over the 8-week study period (mean Y-BOCS total score at week 8 as compared with baseline: P < 0.001 and P < 0.001) without significant difference (P = 0.861). Those receiving duloxetine plus their initial medications experienced a mean decrease of 33.0% in Y-BOCS score and the patients with sertraline added to their initial medication experienced a mean decrease of 34.5% in Y-BOCS.ConclusionsOur double blind controlled clinical trial showed duloxetine to be as effective as sertraline in reducing obsessive and compulsive symptoms in resistant OCD patients. However, it needs to be noted that our study is preliminary and larger double blind placebo controlled studies are necessary to confirm the results.Disclosure of interestThe authors have not supplied their declaration of competing interest.

This 1 week study compared the efficacy of once daily administration of 10 mg loratadine with 120 mg terfenadine in out-patients with seasonal allergic rhinitis. It focussed on the efficacy of treatment at the end of the 24 h period following a daily dose. The study was designed as a double-blind, randomized, parallel-group trial, and 41 patients were enrolled and evaluated for efficacy. Patients took an initial dose at the study site and returned on days 2 and 8. At day 2 (24 h after the initial dose), according to the physician's evaluation 57% of loratadine-treated patients had a good or excellent response, compared to 50% of those given terfenadine. At day 8, 24 h after the final dose, 71% of the loratadine-treated patients and 35% of the terfenadine-treated patients had a good or excellent response ( P = 0.03). At days 2 and 8, reductions in mean symptom scores measured 22, 23 and 24 h after the initial and final doses showed an indication of being greater with loratadine than with terfenadine (non-significant due to small sample size). The incidence of sedation was similar in both groups. It is concluded that 10 mg loratadine, administered once daily, controls the symptoms of rhinitis more effectively than 120 mg terfenadine given once daily in the last few hours of the 24 h dosing period.

Objective of the Review: To collect information, analyse and evaluate previous studies in the use of biofeedback in neurological patients. Key Points. Despite the wide practical application and a lot of available publications, the level of evidence of this method is low because of a small sample size and the challenges with biofeedback mechanism description. A review of various types of biocontrol, its mechanisms and developments shows that drug-free therapy using only patient’s resources (organic, psychological, emotional and volitional) can activate the mechanisms of neuroplasticity, which are poorly studied. Still, it does not prevent from using biocontrol for the therapy of patients and/or prevention of various diseases in healthy population. Conclusion. Biofeedback therapy has proven to be a safe, relatively efficient and easy-to-use method. However, organisation of a large-scale double blind randomized trial is one of the predominant directions in the future. Keywords: biofeedback, biocontrol, neurofeedback, biofeedback therapy.

AbstractBackground: Current opinions regarding the use of dexamethasone in the treatment of chronic subdural hematomas (CSDH) are only based on observational studies. Moreover, the use of corticosteroids in asymptomatic or minimally symptomatic patient with this condition remains controversial. Here, we present data from a prospective randomized pilot study of CSDH patients treated with dexamethasone or placebo. Methods: Twenty patients with imaging-confirmed CSDH were recruited from a single center and randomized to receive dexamethasone (12 mg/day for 3 weeks followed by tapering) or placebo as a conservative treatment. Patients were followed for 6 months and the rate of success of conservative treatment with dexamethasone versus placebo was measured. Parameters such as hematoma thickness and clinical changes were also compared before and after treatment with chi-square tests. Adverse events and complications were documented. Results: During the 6-month follow-up, one of ten patients treated with corticosteroids had to undergo surgical drainage and three of ten patients were treated surgically after placebo treatment. At the end of the study, all remaining patients had complete radiological resolution. No significant differences were observed in terms of hematoma thickness profile and impression of change; however, patients experienced more severe side effects when treated with steroids as compared with placebo. Dexamethasone contributed to many serious adverse events. Conclusions: Given the small sample size, these preliminary results have not shown a clear beneficial effect of dexamethasone against placebo in our patients. However, the number of secondary effects reported was much greater for corticosteroids, and dexamethasone treatment was responsible for significant complications.

A prospective, double-blind clinical study was performed to evaluate the combination of dipyridamole(Persantin)225 mg/day and acetyl salicyclic acid (ASA) 1 g/day prophylaxis of post-operative venous thromboembolism in elective total hip replacement. Patients were stratified according to age, and randomly assigned to receive drug or placebo. All patients were followed with 125I-labelledfibrinogen scanning for one week post-operatively, or until fully mobile. Venography was performed in 67/129 patients; in 27 patients the venogram was obtained to confirm a positive fibrinogen scan, in 40 patients an elective venogram was obtained on the 7th post-operative day to evaluate the operated thigh (a blind area for scanning). Thrombosis (by scan or venogram) was found in 16/66(24%) in the control group, and in 21/63(33%) in the treated group. Overall incidence was 37/129 (29%). Correlation of scan with venography was 90%. There were no clinically significant pulmonary emboli in either group. We conclude that the combination of ASA and dipridamole as given in this study is not effective prophylaxis in elective total hip replacement.

SummaryIn a double-blind study carried out on elderly patients (older than 65 years) the efficacy and tolerability of the new antidepressant moclobemide was compared. Moclobemide belongs to a new class of substances called RIMA (Reversible inhibitor of the monoamine oxidase type A). Fluvoxamine, a selective reuptake-inhibitor of 5-HT, belongs to a class of antidepressants known for their better tolerability compared to tricyclic especially with elderly patients. Forty elderly patients (mean age 75 years) with major depression (according to DSM III) were randomized to receive either moclobemide (300 mg) or fluvoxamine (100 mg) twice daily. Dosages were increased when necessary on day 8, to a maximum of 450 mg moclobemide or 200 mg fluvoxamine and in most cases were maintained at these levels for the remainder of the study period (four weeks). Moclobemide was more effective than fluvoxamine showing a marked antidepressant effect and an earlier effect on psychomotor retardation. The two drugs were well tolerated showing a low incidence of side effects.

390 Background: Propranolol and etodolac (designated VT-122) target the adrenergic and prostaglandin stress systems activated in HCC. These stress-induced systems are proposed to induce changes in the tumor microenvironment and immune system leading to tumor promotion and immune tolerance. In a separate study, administration of VT-122 prior to sorafenib showed an increase in median overall survival (OS) of 21 months when VT-122 is administered before sorafenib compared to 10 months OS for sorafenib alone. The aim of the current study was to evaluate the effect of administering VT-122 at least 30 days after starting sorafenib. Methods: Patients with HCC receiving sorafenib for at least 30 days were eligible for this double-blind, placebo-controlled study. Patients were randomized to receive sorafenib with either VT-122 or placebo. Patients received therapy for up to 12 months or until treatment failure. VT-122 was administered twice daily. The primary endpoint was duration of therapy (DoT) and the secondary endpoint was OS. Results: Twenty patients were randomized, 11 and 9 patients to the VT122 and placebo arm, respectively. Each arm was balanced with regards to age (mean of 60.4 years), Child Pugh status (9 Child Pugh A, 11 Child Pugh B7), hepatitis virus status (6 HBV and 1 HCV positive) and C-reactive protein (CRP) (20.4 mg/L). VT122 with sorafenib was well tolerated with no unexpected serious adverse events reported. Mean OS was 13.9 months and 9.6 months in the VT-122 and placebo arms, respectively. Mean DoT (unvalidated) was 10.1 months and 7.5 months in the VT-122 and placebo arms, respectively. Conclusions: Co-administration of VT-122 with sorafenib was well tolerated and showed an increase in duration of therapy and OS versus sorafenib alone. The small sample size and number of events precludes the ability to make any significant efficacy conclusions. The increase in survival was not as great as that seen in a separate study in which VT122 was started prior to sorafenib. A further Phase 3 study of VT122 administered prior to sorafenib in patients with HCC is warranted. Clinical trial information: NCT01265576.
