Data on the effect of early treatment with ivermectin on viral load, symptoms and humoral response in patients with mild COVID-19.

The trial was conducted in the Pamplona metropolitan area (Navarra, Spain). Patients were enrolled between July 31, 2020 and September 11, 2020 and randomized in a 1:1 ratio to ivermectin (400 mcg/kg) single oral dose or placebo. Assessments on enrollment and at days 4, 7, 14, 21 and 28 post treatment included: general symptoms report, physical examination and adverse events. All patients were asked to complete a daily online diary of symptoms from day 1 to 28 post treatment. On enrollment, as well as on days 7 and 14 blood samples were obtained to assess full blood count, C reactive protein, procalcitonin, ferritin, creatinine phosphokinase, lactic dehydrogenase, troponin T, D dimer, IL-6, and renal function. Viral loads were calculated at enrollment and on days 4, 7, 14 and 21 post treatment based on a nasopharyngeal swab for SARS-CoV-2 PCR (for genes N and E). A semi-quantitative serology for IgG against SARS-CoV-2 was done on samples from all patients on day 21 post-treatment.
