Coronavirus Severe Acute Respiratory Syndrome | Drug: Colchicine Drug: Interferon-Beta Drug: Aspirin Drug: Rivaroxaban | Phase 3 |
The ACT COVID-19 program consists of two parallel trials testing the effects of interventions in complementary populations in outpatients and inpatients.
In the outpatient study, symptomatic patients in the community who are COVID-19 positive and at high risk of disease progression: colchicine compared with control (anti-inflammatory); and ASA compared with control (anti-thrombotic); using a 2 x 2 factorial design. The primary outcome for colchicine vs. control is the composite of hospitalization or death; and the co-primary outcome is disease progression by 2 points on a 7-point scale. The primary outcome for ASA vs. control is the composite of hospitalization or death; and the co-primary outcomes are the composite of major adverse cardiovascular events (MI, stroke, ALI, VTE, death), and disease progression by 2 points on a 7-point scale.
For inpatients, in symptomatic patients who are COVID-19 positive and who are hospitalized: interferon-β is compared with control (anti-viral); colchicine is compared with control (anti-inflammatory); and the combination of ASA and rivaroxaban is compared with control (anti-thrombotic); using a 2 x 2 x 2 factorial design. The primary outcome for interferon-β vs. control, and for colchicine vs. control is the composite of invasive mechanical ventilation or death; and the co-primary outcome is disease progression by 2 points on a 7-point scale. The primary outcome for the combination of ASA and rivaroxaban vs. control is the composite of invasive mechanical ventilation or death; and the co-primary outcomes are the composite of major adverse cardiovascular events (MI, stroke, ALI, VTE, death) and disease progression by 2 points on a 7-point scale.

Arm | Intervention/treatment |
---|---|
Experimental: Colchicine
Outpatients: 0.6 mg twice daily for 3 days, then 0.6 mg once daily for 25 days (total 28 days). Inpatients: 1.2 mg followed by 0.6 mg 2 hours later, then 0.6 mg twice daily for 28 days. (*Depending on availability, 0.6 mg tablets can be substituted by 0.5 mg tablets for a regimen in outpatients of 0.5 mg twice daily for 3 days, then 0.5 mg once daily for 25 days [total 28 days]; and in inpatients of 1.0 mg followed by 0.5 mg 2 hours later, then 0.5 mg twice daily for 28 days). |
