LANSING, Mich., May 18, 2022 /PRNewswire/ -- The companies Atonco (Nantes-Saint Herblain, France) and IONETIX Corporation (Lansing, MI) have signed a partnership agreement to ensure the radioisotope production and supply of the radiopharmaceutical necessary for the success of Atonco's clinical studies and commercialization in the United States.

IONETIX is leading the way by establishing the first North American commercial scale supply of astatine-211, from its new cyclotron facility in Lansing, MI that is dedicated to the production and distribution of alpha-emitting radioisotopes. "We are very excited about the partnership with Atonco which will enable us to fully support their clinical development program and commercialization in the United States, subject to FDA approval of Atonco's drug candidates", declared David Eve, Vice President of Medical Affairs.

"This partnership agreement is a key step in the development of Atonco", declared Sylvain Fanier, President of Atonco.
