Project description:ObjectivesThe study objective is to quantify the effectiveness of ivermectin (subcutaneous/oral IVM) in the presence or absence of zinc (Zn) for clinical and radiological improvement in coronavirus disease 2019 (COVID-19) patients with moderate severity.Trial designThis quadruple-blinded, placebo-controlled randomized clinical trial will be a multiarmed multi-centered study with superiority framework.ParticipantsQuinquagenarian and sexagenarian patients with moderate COVID-19 symptoms and positive severe respiratory syndrome coronavirus -2 (SARS-CoV-2) PCR will be included. Participants with co-morbidities and pregnant women will be excluded. Patient recruitment will be done in Shaikh Zayed Medical Complex, Doctors Lounge and Ali Clinic in Lahore (Pakistan).Intervention and comparatorThe registered patients will be allocated in 6 groups (30 participants each). Patients will be taking subcutaneous IVM at 200 μg/kg/48 h (Arm A) or subcutaneous IVM at 200 μg/kg/48 h and oral Zn 20mg/8 h (Arm B) or oral IVM at 0.2 mg/kg/day (Arm C) or oral IVM at 0.2 mg/kg/day and oral Zn 20mg/8 h (Arm D) or alone oral Zn 20mg/8 h (Arm E) or placebo alone (Arm X). Patients in all arms will receive standard care and respective placebo (empty capsule 8 hourly and/or subcutaneous normal saline 2ml/48 h).Main outcomesPrimary endpoints will be duration of symptomatic phase and SARS-CoV-2 clearance along with high resolution CT (HRCT) chest score and clinical grade scale (CGS) on day 6. 30-day mortality will be documented as a secondary endpoint. SARS-CoV-2 clearance will be calculated by second PCR on day 7. HRCT chest score will be measured by the percentage and lung lobes involvement on day 6 with a maximum score of 25. CGS will be recorded on a seven-point scale; grade 1 (not hospitalized, no evidence of infection and resumption of normal activities), grade 2 (not hospitalized, but unable to resume normal activities), grade 3 (hospitalized, not requiring supplemental oxygen), grade 4 (hospitalized, requiring supplemental oxygen), grade 5 (hospitalized, requiring nasal high-flow oxygen therapy and/or noninvasive mechanical ventilation), grade 6 (hospitalized, requiring ECMO and/or invasive mechanical ventilation) and grade 7 (death).RandomisationA simple lottery method will be used to randomly allocate scrutinized patients in 1:1:1:1:1:1 ratio in 6 groups.Blinding (masking)Patients, primary care physicians, outcome assessors and the data collection team will be blinded.Numbers to be randomised (sample size)180 participants will be randomized into six arms with five investigational and one placebo group.Trial statusInstitutional Review Board Shaikh Zayed Post-Graduate Medical Complex, Lahore, Pakistan has approved the protocol (version 2.3) with ID SZMC/IRB/Internal0056/2020.

Project description:BackgroundThe selective serotonin reuptake inhibitors (SSRIs) fluoxetine and fluvoxamine were repurposed for the treatment of early COVID-19 based on their antiviral activity in vitro, and observational and clinical trial evidence suggesting they prevented progression to severe disease. However, these SSRIs have not been recommended in therapeutic guidelines and their antiviral activity in vivo has not been characterised.MethodsPLATCOV is an open-label, multicentre, phase 2, randomised, controlled, adaptive pharmacometric platform trial running in Thailand, Brazil, Pakistan, and Laos. We recruited low-risk adult outpatients aged 18-50 with early symptomatic COVID-19 (symptoms <4 days) between 5 April 2022 and 8 May 2023. Patients were assigned using block randomisation to one of eleven treatment arms including oral fluoxetine (40 mg/day for 7 days), or no study drug. Uniform randomisation ratios were applied across the active treatment groups while the no study drug group comprised ≥20% of patients at all times. The primary endpoint was the rate of oropharyngeal viral clearance assessed until day 7. Measurements were taken daily between days 0 and 7 and analysed in a modified intention-to-treat population (>2 days follow-up).The viral clearance rate was estimated under a Bayesian hierarchical linear model fitted to the log10 viral densities measured in standardised duplicate oropharyngeal swab eluates taken daily over one week (18 measurements per patient). Secondary endpoints were all-cause hospital admission at 28 days, and time to resolution of fever and symptoms. This ongoing trial is registered at ClinicalTrials.gov (NCT05041907).Findings271 patients were concurrently randomised to either fluoxetine (n = 120) or no study drug (n = 151). All patients had received at least one COVID-19 vaccine dose and 67% were female (182/271). In the primary analysis, viral clearance rates following fluoxetine were compatible with a small or no increase relative to the no study drug arm (15% increase; 95% credible interval (CrI): -2 to 34%). There were no deaths or hospitalisations in either arm. There were no significant differences in times to symptom resolution or fever clearance between the fluoxetine and the no study drug arms (although only a quarter of patients were febrile at baseline). Fluoxetine was well tolerated, there were no serious adverse events and only one grade 3 adverse event in the intervention arm.InterpretationOverall, the evidence from this study is compatible with fluoxetine having a weak in vivo antiviral activity against SARS-CoV-2, although the primary endpoint is also compatible with no effect. This level of antiviral efficacy is substantially less than with other currently available antiviral drugs.FundingWellcome Trust Grant ref: 223195/Z/21/Z through the COVID-19 Therapeutics Accelerator.

Project description:ObjectivesThis study aims to demonstrate the positive effects on oxygenation of flow-controlled ventilation compared to conventionally ventilated patients in patients suffering from Acute respiratory distress syndrome (ARDS) associated with COVID-19.We define ARDS according to the "Berlin" definition integrating the oxygenation index (P/F ratio), the level of Positive End Expiratory Pressure (PEEP), radiological and clinical findings.Trial designThis is a prospective, randomized (1:1 ratio), parallel group feasibility study in adult patients with proven COVID-19 associated ARDS.ParticipantsAll adult patients admitted to the ICU of Hamad Medical Corporation facilities in Qatar because of COVID-19 infection who develop moderate to severe ARDS are eligible. The inclusion criteria are above 18 years of age, proven COVID-19 infection, respiratory failure necessitating intubation and mechanical ventilation, ARDS with a P/F ratio of at least 200mmHg or less and a minimum PEEP 5cmH2O, BMI less 30 kg/ m2. The following exclusion criteria: no written consent, chronic respiratory disease, acute or chronic cardiovascular disease, pregnancy or need for special therapy (prone position and/or Extracorporeal membrane oxygenation).Intervention and comparatorAfter randomisation, the group A patients will be ventilated with the test-device for 48 hours. The settings will be started with the pre-existing-PEEP. The upper pressure will be determined to achieve a tidal volume of 6 ml/kg lean body mass, while the respiratory rate will be set to maintain an arterial pH above 7.2. In group B, the ventilator settings will be adjusted by the attending ICU team in accordance with lung-protective ventilation strategy. All other treatment will be unchanged and according to our local policies/guidelines.Main outcomesThe primary end point is PaO2. As this is a dynamic parameter, we will record it every 6-8 hours and analyse it sequentially.RandomisationThe study team screens the ventilated patients who fulfil the inclusion criteria and randomise using a 1:1 allocation ratio after consenting using a closed envelope method. The latter were prepared and sealed in advance by an independent person.Blinding (masking)Due to the technical nature of the study (use of a specific ventilator) blinding is only possible for the data-analysts and the patients.Numbers to be randomised (sample size)The sample size calculation based on the assumption of an effect size (change in PaO2) of 1.5 SDS in the primary endpoint (PaO2), an intended power of 80%, an alpha error of 5% and an equal sample ratio results in n=7 patients needed to treat. However, to compensate for dropouts we will include 10 patients in each group, which means in total 20 patients.Trial statusThe local registration number is MRC-05-018 with the protocol version number 3. The date of approval is 14th April 2020. Recruitment began 28th May 2020 and is expected to end in September 2020.Trial registrationThe protocol was registered before starting subject recruitment under the title: "Flow controlled ventilation in ARDS associated with COVID-19" in ClinicalTrials.org with the registration number: NCT04399317 .
