RCT 38 low risk outpatients in Japan, showing no significant differences for colchicine and low-dose aspirin compared to loxoprofen. Hospitalization was lower, without statistical significance (4.3% vs. 13.3%, p=0.34). There were no critical cases, deaths, or severe adverse events in either group.
Colchicine: 1.0mg loading dose, followed approximately half a day later by 0.5mg twice daily for 10 doses, and then 0.5 mg once daily for four doses. Aspirin: 100mg daily for 10 days. Both groups received probiotics and acetaminophen.
Study covers aspirin and colchicine.

Oral Colchicine and Low-Dose Aspirin Combination Therapy for Nonelderly, Non-severe, Early Time From Onset, Adult Outpatients with Coronavirus Disease 2019 (COVID-19) during "The Fifth Pandemic Wave" in Japan

Background: Treatment with antiviral drugs for non-severe, early time from onset, adult outpatients with Coronavirus Disease 2019 (COVID-19) had not been established in 2021. However, some new variants of SARS-CoV-2 had caused rapid exacerbation and hospitalization among non-elderly outpatients with COVID-19, contributing to widespread crises within healthcare systems. Methods: From July to October 2021, we urgently assessed a therapeutic program using oral colchicine (1.0 mg loading dose, followed approximately half a day later by 0.5 mg twice daily for 5 days, and then 0.5 mg once daily for 4 days) and low-dose aspirin (100 mg once daily for 10 days), for non-elderly, non-severe, early time from onset, adult outpatients with COVID-19. To verify its effectiveness, we set loxoprofen as a control arm, and comparison of these two arms was performed. The primary outcomes were hospitalization, criticality, and death rates. Results: Thirty-eight patients (23 receiving colchicine and low-dose aspirin [CA]; 15 receiving loxoprofen [LO]) were evaluated. Hospitalization rate was lower in the CA group (1/23; 4.3%) than in the LO group (2/15; 13.3%); however, no significant difference was found between the two groups (p=0.34). No critical cases, deaths, or severe adverse events were found in either group. Conclusions: Our CA regimen did not show superiority over LO treatment. However, our clinical experience should be recorded as part of community health care activities carried out in Kurume City against the unprecedented COVID-19 pandemic.
