We assessed the efficacy and safety of colchicine and low-dose naltrexone (LDN), alone and in combination, in preventing progression to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. In this prospective, randomized, open-label trial, colchicine and LDN were compared to standard of care (SOC) in patients hospitalized with SARS-CoV-2 not requiring high levels of ventilatory support. Patients were randomly assigned to colchicine alone, LDN alone, colchicine/LDN in combination, or SOC. The primary outcome was time to disease recovery. Secondary outcomes included total time hospitalized, study enrollment, level of care, oxygen support, and adverse events. One-hundred and thirty-seven patients were randomized (N c = 34, N c+ldn = 33, N ldn = 35, N soc = 35). Eightyfour patients (61%) achieved disease recovery by day 5. There was no significant difference in the proportion of patients who experienced the primary efficacy outcome among those who received colchicine, LDN, or between the four study arms. Patients receiving colchicine had a shorter length of enrollment but not a significant reduction in the length of stay. Diarrhea was the most common adverse reaction. In adults hospitalized with SARS-CoV-2 not requiring high-level ventilatory support, colchicine and LDN, alone and in combination, were not associated with significant reductions in progression to severe disease.
