About Aktis Oncology

Aktis Oncology is a clinical stage biotechnology company pioneering the discovery and development of novel targeted alpha radiopharmaceuticals to treat a broad range of solid tumors. The company's first of several pipeline programs targets Nectin-4, a tumor-associated antigen found in urothelial and other solid cancers. Founded and incubated by MPM BioImpact, the company has developed its proprietary miniprotein radioconjugate platform to generate tumor targeting agents with properties ideal for alpha radiopharmaceuticals. Designed to maximize tumor killing through high penetration followed by internalization and retention in cancer cells, Aktis's miniprotein radioconjugates quickly clear from other areas of the body, thereby maximizing anticancer activity while minimizing side effects of treatment. The Aktis platform is isotope-agnostic and further enables clinicians to visualize and verify target engagement with imaging isotopes prior to exposure to therapeutic radioisotopes. Aktis also has a strategic collaboration with Eli Lilly and Company to leverage its miniprotein platform to develop novel radioconjugates outside of Aktis' proprietary pipeline.
