    Dear Editor

    The small randomized clinical trial by Lopes MI et al. has shown a meaningful benefit of colchicine in COVID- 19 patients. However, there are ambiguities in the written study design including the techniques opted for allocation concealment, blinding, and sample size calculations with six primary endpoints. Investigators were not able to analyze four major endpoints including mortality rate, causes of mortality, admission to ICU, and length of stay in ICU [1]. These results became hard to compare with other major studies such as preliminary findings of the RECOVERY trial where investigators have closed the recruitment of colchicine arm. There was no convincing evidence of mortality benefit in the colchicine group. Final results will show more data on secondary outcomes such as length of hospital stay and need for invasive mechanical ventilation [2].
    This may not be the end of the road for colchicine as 26 study groups have been registered with clinicaltrial.gov to prove the beneficial effects of colchicine in COVID patients. At least four of these studies have already been completed. Preprint data from the COLCORONA trial shows a controversial conclusion of reduction in composite rate of death or hospitalization with colchicine in PCR confirmed non hospitalized patients [3]. Another small size COLORIT trial by Mareev V.Yu. et al. showed the median SHOCS score decreased from 8 to 2, i.e., from a moderate to a mild degree in the colchicine group. The...
