Ivermectin Reproposing for Mild Stage COVID-19 Outpatients — IVER-Leve  

Covid19 Clinical Trial

Official title: Ivermectin Reproposing for COVID-19 Treatment in Outpatients With Mild Stage

Status Completed

Clinical Trial Summary

Background: The emergency of COVID-19, along with the current difficulties in responding to the high demand for vaccines, requests to the scientific community to find alternative treatments based on reuse of drugs as a strategy to prevent the progression of the disease in patients infected with SARS COV 2. Objetive This study aims to evaluate the use of ivermectin in mild-stage patients to increase outpatient discharge and prevent the progression to moderate or severe stages of the disease. Added value of this study We found that an intervention with ivermectin has impacted on the PPS in a population of outpatients care, between the 5th and 9th day. Also, the treatment increased the probability to obtain outpatient discharge, even in the presence of comorbidities. Implications of all available evidence. Research in Context According to the COVID-19 Treatment Guidelines by the NIH, most trials have several limitations. It needs results from adequately powered and well-designed clinical trials to provide evidence-based guidance on the role of ivermectin in the treatment of COVID- 19. However, our study shows overlaps in benefits with other authors, and taking together, these results are encouraging for further study about repurposing ivermectin for the treatment of COVID-19.

Clinical Trial Description

Technical Design: Cluster Randomised Trials in outpatients care, n = 254. The subjects were divided into experimental (EG: n = 110) and control groups (CG: n = 144). The criteria for this choice were based on the geographical distribution of Health Services, locomotion, and logistics in current times of pandemic. Sample Size: Sample size was determined by the test comparing two proportions. It considered the following parameters to the bilateral test: n = 30,000 Total operating area population for services network to Primary Care; 95% confidence level, 3% precision, 5% proportion, n = 201 sample size without loss, 20% expected proportion of losses. The sample size calculated was n= 252 participants. Participants: The total group n = 254 enrolled outpatients care from the urban area-department heads and peri-urban area of the City San Miguel de Tucumán. The study was conducted between September 2020 to January 2021. The health coverage service was administered by the Health System of the State of Tucumán (SI.PRO.SA, Tucumán, Argentina). The people who agreed to participate in the study gave their informed consent before starting the study (Research Ethics Committee / Health Research Directorate, file number 054/2020). Intervention Protocol: The EG received protocol ivermectin orally 4 tablets of 6 mg = 24 mg every 7 days for 4 weeks plus symptomatic treatment (500mg paracetamol every 6 or 8h, no more than 4 tablets daily;100mg aspirin, 1 tablet per day with breakfast; 150mg Ranitidine, 1 tablet in the morning, and 1 tablet at night). The CG received only symptomatic treatment. Patients with comorbidities continued with the basic medication for the underlying pathology . All participants were evaluated by physical examination and COVID-19 infection was diagnosed with positive RT-PCR. Clinical evaluation of symptoms was carried throughout the study period. Enrolled subjects completed symptom questionnaires (including reporting of any adverse effects of treatment), physical examinations and remote clinical telemedicine follow-up and received outpatient discharge 4 weeks after the start of the intervention. The 10-category ordinal scale recommended by the WHO was used to classify patients according to clinical patient state: ambulatory mild disease, moderate disease, severe disease. ;
