Who We Are
Refle Xion elevates radiopharmaceuticals from drugs that help identify cancer to guides that actively direct external beam radiotherapy by leveraging tumor biology. Designated an FDA Breakthrough Device for lung tumors, Refle Xion's SCINTIX® biology-guided radiotherapy aims to overcome long‑standing barriers preventing definitive radiotherapy for metastatic disease. FDA‑cleared SCINTIX therapy automates targeting and motion management for use in FDG‑guided treatment of lung and bone tumors that arise from primary lung and bone cancers or are metastases from other primary cancers.
In strategic collaborations with industry‑leading radiopharmaceutical companies, Refle Xion is co‑developing and co‑commercializing disease‑specific radiotracers for treating late‑stage cancers.
