At Asher Biotherapeutics, we are pioneering a new approach with our cis‑targeted immunotherapies. Our immunotherapies selectively activate only the immune cell types that drive the desired therapeutic response. With this innovation, we address an inherent shortcoming of conventional immunotherapies, which indiscriminately act on multiple cell types, resulting in suboptimal efficacy and side effects.

Cis-targeting: Achieving the next level of selectivity for immunotherapies

What is cis-targeting?

Cis-targeted immunotherapies engage two molecules on the same immune cell: an immunomodulatory receptor and a specific target that directs the therapy to the desired immune cell type.

OUR PLATFORM

Why is our immunotherapy approach unique?

By only activating the immunomodulatory receptor when the targeted antigen is present on the same cell, our cis-targeted immunotherapies offer a new level of selectivity, with optimized efficacy and minimized toxicity.

Separating the curves with IL-2, a powerful mediator of the immune system

The lead molecule in our pipeline, AB248, a cis-targeted IL-2 that specifically activates CD8+ effector T cells, has shown initial evidence of compelling anti-tumor activity with a well-tolerated safety profile in the ongoing Phase 1a/1b clinical trial.

Our experienced team is focused on what matters most: patients

Captured in our mission, our name, and our guiding principles is the belief that our medicines can have significant impact, along with the need for urgency to make rapid progress for patients.
