Closing in on Cancer

At Merus, we are clinically advancing leading-edge, targeted treatments to address the unmet needs of patients with various types of cancer. Utilizing our proprietary technology platforms, we are developing innovative multispecific antibody therapeutics, referred to as Multiclonics^®.

Multispecific
antibody
platform

Our Multiclonics^® therapeutics are full-length human IgG bispecific (Biclonics^®) and trispecific (Triclonics^®) antibodies that bind to multiple targets, and are manufactured with advantageous features for anti-cancer effects against the complex mechanisms that drive cancer. Multiclonics^® are capable of being developed with industry standard processes and have been observed in preclinical studies to have similar features as conventional monoclonal antibodies, such as long half-life and low immunogenicity.

Established
clinical
pipeline

Our therapeutic candidates engage cancer antigens and harness the power of the immune system to kill tumor cells in unique and powerful ways by utilizing our proprietary technology platform and deep expertise in oncology. We are currently developing a broad pipeline of wholly owned and licensed Biclonics^® drug candidates in the clinic with compelling target combinations and unique mechanisms of action.

Lead
asset
petosemtamab

Our lead cancer drug candidate is petosemtamab, a Biclonics^® antibody with a EGFR X LGR5 target combination. Petosemtamab has shown encouraging single agent clinical activity in patients with previously treated head and neck cancer, an area of significant unmet medical need.
