dc.description.abstractA WHO panel, convened during the 2014 Ebola virus epidemic, assessed the ethical implications of using medicines that have shown promising results in the laboratory and in animal models, but before they have been evaluated for safety and efficacy in humans. They concluded that researchers have a moral duty to evaluate unproven interventions (for treatment or prevention) in clinical trials that are of the best possible design in exceptional circumstances. Circumstances such as apply today. In our view, the description “clinical trials that are of the best possible design”, where therapeutic interventions are concerned, implies adequately masked randomized controlled trials. But more trials of pharmacological interventions are being conducted in the treatment of COVID-19 without blinding (or masking) of interventions than are being conducted masked. Some single-blind trials mask only the participant rather than the investigator. A minority are placebo-controlled. Trials of non-pharmacological interventions are being even less well served, relying largely on retrospective studies and mathematical models of uncertain value. We believe this to be a potential waste of participants’ and investigators’ time and therefore unethical. Biased results can distort therapeutic decision-making, public perceptions, investment in healthcare, and the standing and value of medical research. They may falsely suggest a lack of equipoise, discouraging investigators from performing well designed clinical trials and make recruitment to such trials difficult. They may result in more harms than benefits.en_US
