A randomized open-label trial to evaluate the efficacy and safety of triple therapy with aspirin, atorvastatin, and nicorandil in hospitalised patients with SARS Cov-2 infection: A structured summary of a study protocol for a randomized controlled trial.

Project description:Objectives- To describe the evolution of the SARS-CoV-2 salivary viral load of patients infected with Covid-19, performing 7 days of tri-daily mouthwashes with and without antivirals. - To compare the evolution of the SARS-CoV-2 nasal and salivary viral load according to the presence or absence of antivirals in the mouthwash.Trial designThis is a multi-center, randomised controlled trial (RCT) with two parallel arms (1:1 ratio).ParticipantsInclusion criteria - Age: 18-85 years old - Clinical diagnosis of Covid-19 infection - Clinical signs have been present for less than 8 days - Virological confirmation - Understanding and acceptance of the trial - Written agreement to participate in the trial Exclusion criteria - Pregnancy, breastfeeding, inability to comply with protocol, lack of written agreement - Patients using mouthwash on a regular basis (more than once a week) - Patient at risk of infectious endocarditis - Patients unable to answer questions - Uncooperative patient The clinical trial is being conducted with the collaboration of three French hospital centers: Hospital Center Emile Roux (Le Puy en Velay, France), Clinic of the Protestant Infirmary (Lyon, France) and Intercommunal Hospital Center (Mont de Marsan, France).Intervention and comparatorEligible participants will be allocated to one of the two study groups. Intervention group: patients perform a tri-daily mouthwash with mouthwash containing antivirals (β-cyclodextrin and Citrox®) for a period of 7 days.Control grouppatients perform a tri-daily mouthwash with a placebo mouthwash for a period of 7 days.Main outcomesPrimary Outcome Measures: Change from Baseline amount of SARS-CoV-2 in salivary samples at 4 and 9 hours, 1, 2, 3, 4, 5 and 6 days. Real-time PCR assays are performed to assess salivary SARS-CoV 2 viral load.Secondary outcome measuresChange from Baseline amount of SARS-CoV-2 virus in nasal samples at 6 days. Real-time PCR assays are performed to assess nasal SARS-CoV-2 viral load.RandomisationParticipants meeting all eligibility requirements are allocated to one of the two study arms (mouthwash with β-cyclodextrin and Citrox® or mouthwash without β-cyclodextrin and Citrox®) in a 1:1 ratio using simple randomisation with computer generated random numbers.Blinding (masking)Participants, doctors and nurses caring for participants, laboratory technicians and investigators assessing the outcomes will be blinded to group assignment.Numbers to be randomised (sample size)Both the intervention and control groups will be composed of 103 participants, so the study will include a total of 206 participants.Trial statusThe current protocol version is 6, August 4th, 2020.

Project description:ObjectivesConsidering the therapeutic potential of honey and Nigella sativa (HNS) in coronavirus disease 2019 (COVID-19) patients, the objective of the study is defined to evaluate the prophylactic role of HNS.Trial designThe study is a randomized, placebo-controlled, adaptive clinical trial with parallel group design, superiority framework with an allocation ratio of 1:1 among experimental (HNS) and placebo group. An interim analysis will be done when half of the patients have been recruited to evaluate the need to adapt sample size, efficacy, and futility of the trial.ParticipantsAll asymptomatic patients with hospital or community based COVID-19 exposure will be screened if they have had 4 days exposure to a confirmed case. Non-pregnant adults with significant exposure level will be enrolled in the study High-risk exposure (<6 feet distance for >10min without face protection) Moderate exposure (<6 feet distance for >10min with face protection) Subjects with acute or chronic infection, COVID-19 vaccinated, and allergy to HNS will be excluded from the study. Recruitment will be done at Shaikh Zayed Post-Graduate Medical Institute, Ali Clinic and Doctors Lounge in Lahore (Pakistan).Intervention and comparatorIn this clinical study, patients will receive either raw natural honey (0.5 g) and encapsulated organic Nigella sativa seeds (40 mg) per kg body weight per day or empty capsule with and 30 ml of 5% dextrose water as a placebo for 14 days. Both the natural products will be certified for standardization by Government College University (Botany department). Furthermore, each patient will be given standard care therapy according to version 3.0 of the COVID-19 clinical management guidelines by the Ministry of National Health Services of Pakistan.Main outcomesPrimary outcome will be Incidence of COVID-19 cases within 14 days of randomisation. Secondary endpoints include incidence of COVID-19-related symptoms, hospitalizations, and deaths along with the severity of COVID-19-related symptoms till 14th day of randomization.RandomisationParticipants will be randomized into experimental and control groups (1:1 allocation ratio) via the lottery method. There will be stratification based on high risk and moderate risk exposure.Blinding (masking)Quadruple blinding will be ensured for the participants, care providers and outcome accessors. Data analysts will also be blinded to avoid conflict of interest. Site principal investigator will be responsible for ensuring masking.Numbers to be randomised (sample size)1000 participants will be enrolled in the study with 1:1 allocation.Trial statusThe final protocol version 1.4 was approved by institutional review board of Shaikh Zayed Post-Graduate Medical Complex on February 15, 2021. The trial recruitment was started on March 05, 2021, with a trial completion date of February 15, 2022.Trial registrationClinical trial was registered on February 23, 2021, www.clinicaltrials.gov with registration ID NCT04767087 .Full protocolThe full protocol is attached as an additional file, accessible from the Trials website (Additional file 1).

Arm 2: Placebo MAIN OUTCOMES: Primary outcome: Time to virological cure as defined by 2 successive throat (or combined nose/throat) swabs negative for SARS-CoV-2 by nucleic acid testing during the 14 days after enrolment.RandomisationRandomisation performed at the Alfred Hospital Clinical Trials Pharmacy using computer generated block-randomisation lists with 6 participants per block. Within each block half of the participants will be randomised to the candidate antiviral and the other half to placebo. Randomisation is stratified by study site, with participants enrolled in the community considered as a study site.Blinding (masking)Study participants, study investigators and the study statistician will be blinded to treatment allocation.Numbers to be randomised (sample size)The study aims to recruit 190 people (95/arm) with the first candidate antiviral favipiravir TRIAL STATUS: Protocol version 2.0 Dated 31-Jul-2020.
