All favorable results to date have been reported in moderate to severe cases.
Colchicine is a cheaper option with even more favorable results in a Greek RCT:

Similar results from each, but second one is small and neither are RCTs.
Would be nice to see a larger RCT on this. I think it likely makes sense for suppressing neutrophil infiltration and NETosis.
