  • Patent number: 12384824
    Abstract: The present invention provides a method for producing active hepatocyte growth factor activator (HGFA) and active hepatocyte growth factor (HGF) without using animal serum. The present invention relates to a method for producing active HGFA without using animal serum. The method is characterized in that it comprises a step of obtaining a culture supernatant comprising pro-HGFA by culturing mammalian cells expressing inactive hepatocyte growth factor activator (pro-HGFA) in a medium without serum, and a step of adjusting the culture supernatant comprising pro-HGFA obtained in the above step to weakly acidic to convert pro-HGFA into active HGFA. The present invention also relates to a method for producing active HGF with HGFA produced by said method.

  • Patent number: 12365743
    Abstract: Provided herein are novel anti-CD28× anti-PSMA antibodies and methods of using such antibodies for the treatment of PSMA-associated cancers. Subject anti-CD28× anti-PSMA antibodies are capable of agonistically binding to CD28 costimulatory molecules on T cells and PSMA on tumor cells. Thus, such antibodies selectively enhance anti-tumor activity at tumor sites while minimizing peripheral toxicity. The subject antibodies provided herein are particularly useful in combination with other anti-cancer therapies (e.g., anti-CD3× anti-PSMA antibodies) for the treatment of prostate cancers.
