President Trump received the therapy when he was battling the coronavirus that has cost more than 250,000 Americans their lives.
The cocktail contains two antibodies produced in a lab and can be given to patients who are newly infected.
Regeneron says it will have doses ready for 80,000 patients this month, and enough for a half-million more by the end of January.
