It looks like Actemra by Roche, another anti-IL6 mab, also undergoing trial. Since Regeneron and Roche are much bigger than us, Fauci could be referring to them.

Patterson did mention that he believes that Leronlimab modulates IL-6, TNF and T suppressor so the clinical response maybe more powerful than drugs just targeting one of these molecules. This is where Ohm maybe able to do more DD for us.
