About Immunome

Immunome is a biopharmaceutical company that utilizes its proprietary human memory B cell platform to discover and develop antibody therapeutics to improve patient care. The company’s focus is on discovering and developing therapeutics in oncology internally and in collaboration with its partners.

Immunome’s proprietary Discovery Engine identifies novel therapeutic antibodies and their targets through an unbiased interrogation of human memory B cells, highly educated components of the immune system, isolated from patients. Memory B cells are key elements in the human immune system response to disease as they produce specific, high-affinity antibodies that bind to cancer antigens or pathogens. Immunome’s Discovery Engine incorporates high-throughput screening to enable efficient, unbiased, broad, and deep functional evaluation of patient memory B cell repertoires to identify antibodies directed at novel targets. The functional data Immunome generates differentiates Immunome’s approach from those that use deep sequencing of B cells to identify dominant clones that are common within and across patients and assumes genomic dominance is a hallmark of therapeutic utility.
