Ariceum Therapeutics creates systemic targeted radiotherapy (STR) agents that combine tumor‑specific ligands with alpha‑emitting isotopes, delivering potent, short‑range radiation while enabling real‑time PET or SPECT imaging. This integrated diagnostic‑therapeutic approach aims to improve precision, reduce off‑target toxicity, and expand treatment options for metastatic cancers such as small‑cell lung cancer and Merkel cell carcinoma.

Current cancer treatments often lack the ability to simultaneously visualize tumors and deliver highly localized radiation, leading to systemic side effects and limited efficacy for metastatic disease.
Ariceum Therapeutics develops systemic targeted radiotherapy (STR) agents that combine diagnostic imaging and therapeutic radiation in a single radiopharmaceutical. By conjugating tumor‑specific ligands to alpha‑emitting isotopes, the platform delivers potent, short‑range radiation directly to cancer cells while enabling real‑time PET or SPECT imaging to monitor distribution and response. The approach aims to improve treatment precision, reduce off‑target toxicity, and expand therapeutic options for hard‑to‑treat cancers such as small‑cell lung cancer and Merkel cell carcinoma. Clinical programs evaluate safety, biodistribution, and efficacy of these agents in early‑phase trials.
Primary customers are oncology clinicians and pharmaceutical partners developing targeted radiopharmaceutical therapies for metastatic and refractory cancers.
