  • Anti-CD28 compositions
    Patent number: 11591401
    Abstract: Provided herein are novel anti-CD28×anti-B7H3 (also referred to as “?CD28×?B7H3”) heterodimeric bispecific antibodies and methods of using such antibodies for the treatment of cancers. Subject ?CD28×?B7H3 antibodies are capable of agonistically binding to CD28 costimulatory molecules on T cells and targeting to B7H3 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 for enhancing anti-tumor activity when used in combination with other anti-cancer therapies.
