1/ Cuomo’s office says NY trial results on hydroxychloroquine will be released April 20.

Few details are available, but it seems HCQ was primarily used in hospitalized patients.

With the current state of NY hospitals, it's likely only the sickest #COVID19 patients received HCQ.

2/ Treatment of advanced stage COVID-19 w/ HCQ will likely show minimum to no benefit. (Bear in mind it can take ~2 days for HCQ to reach therapeutic levels.)

First, the benefit of viral load reduction from HCQ may no longer be important once the cytokine storm path is activated

3/ Secondly, although HCQ has anti-inflammatory/immunosuppressive properties, it is probably minimally effective at inhibiting cytokine storm/CRS in late stage COVID-19.

Alternative agents such as the anti-IL-6 monoclonal antibody Tocilizumab may be more effective in late cases.

4/ Lastly, HCQ doesn't reverse lung damage or magically clear lung debris.

@raoult_didier Dr. Zelenko ( @zev_dr) @riganoESQ & I believe HCQ is most effective in EARLY treatment when viral load reduction is critical...in line with well-known antivirals for other acute infections.

Hopefully needless to say, but this is not intended as medical advice. Consult your physician regarding prescription drugs.
