About Aktis Oncology

Aktis Oncology, Inc. is a clinical-stage oncology company focused on expanding the breakthrough potential of targeted radiopharmaceuticals to large patient populations, including those not addressed by existing platform technologies. Aktis’ most advanced pipeline program targets Nectin-4, a miniprotein radioconjugate with multi-indication potential across multiple tumor types. Founded and incubated by MPM BioImpact, Aktis has developed its proprietary miniprotein radioconjugate platform to selectively deliver the tumor-killing properties of radioisotopes to targeted tumors. Designed to maximize tumor killing through high penetration followed by internalization and retention in cancer cells, Aktis’ miniprotein radioconjugates are designed to quickly clear from normal organs and tissues, 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.
