Wasn’t there another korean company with different recombinant human hyaluronidase (not caffeine) that had an agreement with Merk for Keytruda? If I remember correctly, Merk dumped them and decided to do its own SC alone which up until recently I thought was without any hyaluronidase. However, the study I posted shows that it is with hyaluronidase. Whose? Will it not be a patent violation?
You are probably right. And in any case, I doubt that Comera and caffeine will become a major threat. But the fact that Merck and other companies seem to be making progress with some form of hyaluronidase while Halo hasn't been able to sign a lot of new deals in the past few years is concerning.
