Astellas Logo

In 2021, Actinium and Astellas announced a continuation of our collaborative research partnership focused on developing theranostics to both image and diagnose solid tumor cancers and treat them leveraging Actinium’s AWE technology platform to utilize the Ac-225 radioisotope warhead with select targeting agents owned by Astellas as part of its Rx+© initiative.

Astellas Pharma Inc. is a pharmaceutical company conducting business in more than 70 countries around the world. Astellas promotes its Focus Area Approach that is designed to identify opportunities for the continuous creation of new drugs to address diseases with high unmet medical needs by focusing on Biology and Modality.

AVEO Oncology Logo

In February 2022, Actinium and AVEO entered into a research collaboration to develop a first in class HER3 (ErbB3) targeting radiotherapy using the Actinium-225 radioisotope warhead for solid tumors. AVEO's HER3 targeting antibodies are designed to inhibit both ligand-dependent and ligand-independent signaling. HER3 is a receptor that is typically expressed in many human cancers and has demonstrated preclinical activity in multiple tumor models.

EpicentRx Logo

In January 2022, we announced a Strategic Research Collaboration with EpicentRx, Inc. to combine targeted radiotherapy with EpicentRx’s CD47-SIRPα immunotherapy RRx-001, which has been studied in Phase 3 clinical trials in lung cancer. At the Society of Immunotherapy for Cancer (SITC) meeting in November 2021 and American Association for Cancer Research (AACR) we presented the first ever data combining targeted radiotherapy with a CD47 immunotherapy, magrolimab which is being developed by Gilead Sciences, and showed that targeted radiotherapy increased cell surface calreticulin and “eat me” signal that resulted in increased phagocytosis and enhanced tumor growth inhibition. In this collaboration, we will leverage our clinical experience with targeted radiotherapies for patients with AML and will work to advance our targeted radiotherapy with RRx-001 to the clinic.
