Study Description

Brief Summary:

The trial aims to assess the impact of cheap, licenced and widely available investigational products on the natural history of SARS-CoV-2 infection in 2 groups of patients - those with mild or moderate pneumonia (Cohort 1) and those with severe pneumonia (Cohort 2), through randomisation to non-identical placebo or intervention arm.

Condition or disease	Intervention/treatment	Phase
Covid-19	Drug: Ivermectin; Drug: ASP; Drug: Placebo	Phase 3

Detailed Description:

The trial is adaptive in design, with the option to change the investigational products should evidence change on the benefits/harms of the interventions being trialed.

Cohort 1. Currently index cases with mild COVID-19 or moderate pneumonia will be randomized to ivermectin 0.3-0.4mg/Kg daily for 3 days (arms 1 and 2) or non-identical placebo (arm 3). Index case randomization will also include HH members who will be treated with ivermectin 0.3-0.4mg/Kg daily for 3 days (arm 1) or non-identical placebo (arms 2 and 3). All households will receive a preventative package (containing soap, bleach, cloth facemasks and instructions on their use).

Cohort 2. Patients admitted to hospital meeting WHO criteria for severe COVID-19 pneumonia will be randomized to aspirin 150mg daily or non-identical placebo for 28 days or until hospital discharge (whichever is sooner). Other care will follow National guidelines.

The study will be conducted at multiple sites in The Gambia, with the option to recruit from other West African countries should this be necessary (subject to further local ethical review/s).
