Spotlight on botensilimab

Agenus’ next-generation CTLA-4 antibody

Botensilimab was designed to:



Innovation in immunotherapy

What is immunotherapy for cancer?

Today, we can create drugs that empower the immune system to do its job – cure disease.

How does botensilimab work?

By modifying the Fc “tail” of the antibody, our scientists discovered that its efficacy and tolerability can be significantly enhanced.

Why Agenus?

Our diverse portfolio of immunotherapies, vertically integrated capabilities from discovery through manufacturing, and partnerships with industry leaders uniquely position us to adopt a comprehensive approach to discover and develop cancer therapies.

By the numbers

Agenus discovers, manufactures, and develops immuno-oncology (I-O) therapeutics. Our vision is to expand the patient population benefiting from I-O through combination approaches that leverage a broad repertoire of antibody therapeutics, adoptive cell therapies (through subsidiary MiNK Therapeutics), adjuvants and vaccines (through subsidiary SaponiQx).

Acceleration through partnerships

While we retain ownership in the majority of our programs, we have accelerated the development of select programs through partnerships with industry leaders. These partnerships generate capital to further support our pipeline development, and many offer optionality for future participation in development and commercialization.

Who we are

We have brought together top talent and expertise to advance our mission, building a team of over 400 employees across our offices in the US and Europe.
