Good post and topic, but I'll disagree that the US Gov will rush to sponsor a mavrilimumab trial. Kiniksa is already running their own trial with results coming later this year. One thing we have learned is, even these small NIH studies move very slowly. Will they get faster, probably, but Lenz was selected late July 2020!
In the meanwhile our HGEN results are coming very soon. If it meets primary endpoint with great results, it will be SOC for hospitalized patients and continue to be studied by NIH. Even with mediocre but EUA-able results studies will continue. If the trial fails I think other MoAs will be studied, not mavrilimumab.
Just my opinion...
