Research and Development Areas

Immuno-oncology Focus
Agenus’s primary research and development (R&D) focus is in immuno-oncology, where it dedicates extensive resources to developing therapies that can engage and modulate the immune system to combat cancer. The company has consistently pursued strategies to activate T cells, natural killer (NK) cells, and other immune components to overcome tumor-induced immunosuppression. One of the central tenets of their immuno-oncology portfolio is the development of checkpoint inhibitors such as anti-CTLA-4 and anti-PD-1 antibodies. For instance, botensilimab (an Fc-enhanced anti-CTLA-4 antibody) and balstilimab (an anti-PD-1 antibody) are flagship programs that exemplify Agenus’s efforts in this space. Moreover, the company’s research extends into combination approaches where these agents are used together to potentially synergize their effects, thereby broadening the scope of therapeutic impact in treatment-resistant solid tumors.

Immuno-oncology research at Agenus is not limited to standalone agents. The company has also embraced the emerging paradigm of combining immune checkpoint inhibitors with adoptive cell therapies. Through its subsidiary MiNK Therapeutics, Agenus explores the use of invariant natural killer T (iNKT) cell therapies to further potentiate anti-tumor responses. This strategy leverages both innate and adaptive arms of the immune system, addressing tumor heterogeneity and microenvironment complexities that often render patients unresponsive to monotherapies. In addition, the company has demonstrated clinical proof-of-concept in early phase trials where responses in traditionally "cold" tumors – those that are less inflamed and generally resistant to immunotherapies – have shown promising signs of immune activation.

Vaccine Development
Alongside its core immuno-oncology efforts, Agenus has positioned itself in the realm of vaccine development by integrating novel adjuvant technologies into its R&D pipeline. Vaccine adjuvants are components that boost the immune response to an antigen, and Agenus’s proprietary QS-21 STIMULON™ platform is at the heart of its vaccine strategy. This adjuvant technology has been showcased in collaboration with partners such as GSK, where it features in vaccines like Shingrix – a vaccine known for its durability and robust protection against herpes zoster. By developing a sustainable, scalable, and eco-friendly plant cell culture-based manufacturing process, the company is well prepared to address not only niche oncology vaccine needs but also broader vaccination campaigns amid global pandemics.

The company’s vaccine research extends into both oncological and infectious disease settings. Their approach aims at using adjuvants to shape a more potent and long-lasting immune response, which is critical in settings where the antigenic stimulus from the target (be it tumor antigens or viral proteins) might not be sufficient on its own. By leveraging its manufacturing expertise and innovation in saponin-based formulations, Agenus is exploring vaccine candidates that potentially could address emerging viral threats, as well as improve cancer vaccine efficacy.

Novel Antibody Therapies
Novel antibody therapies represent another cornerstone of Agenus’s R&D efforts. The company has built a comprehensive antibody discovery platform that is designed to not only generate next-generation antibodies against well-known checkpoints (such as CTLA-4 and PD-1) but also to explore new targets such as TIGIT, CD96, and beyond. The development of AGEN1571, for example, demonstrates superiority in potency compared to conventional competitors by enhancing immune cell activation when used in combination with agents like botensilimab or balstilimab.

Furthermore, Agenus is expanding its expertise into the development of bispecific antibodies. These antibodies are engineered to simultaneously engage two targets, thereby offering a more sophisticated level of immune modulation. Such bispecific formats allow for enhanced targeting of immune cells and tumor cells, leading to improved anti-tumor activity. The differentiation between conventional monoclonal antibodies and these next-generation formats lies in their ability to modulate multiple immune checkpoints concurrently. This approach not only underscores the depth of Agenus’s R&D focus but also positions them at the forefront of innovative antibody engineering strategies that could redefine standard treatment paradigms in oncology.
