## [Radioligand Therapy Production in Carlsbad, CA](/us-en/radioligand-therapy-production-carlsbad-california "Radioligand Therapy Production in Carlsbad, CA") In 2025, our Carlsbad, California, site opened and became our third US site dedicated to manufacturing radioligand therapies (RLT). RLT is a type of precision treatment that pairs a tumor-targeting molecule (ligand) with a therapeutic radioisotope, allowing radiation to be delivered directly to the tumor while minimizing harm to surrounding healthy tissue. The Carlsbad site is built for further expansion to support current and future demand and ongoing innovation in RLT. ![Radioligand therapy manufacturing facility in Carlsbad, CA. ](/us-en/sites/novartis_us/files/styles/crop_freeform/public/2025-11/Radioligand%20therapy%20manufacturing%20facility%20in%20Carlsbad%2C%20CA.jpg.webp?itok=pgNHpOKF "Radioligand therapy manufacturing facility in Carlsbad, CA.
