About Oncoinvent

Oncoinvent is a clinical-stage biotechnology company developing novel

radiopharmaceutical therapies against cancer. The lead product candidate,

Radspherin®, uses the alpha-emitting radionuclide radium-224, directly targeting

micro-metastases post-surgery, harnessing the benefits of modern

radiopharmaceuticals without the complexities of biological targeting.

Oncoinvent is investigating the safety and efficacy of Radspherin® in a clinical

development program in two indications. One Phase 1 trial and one Phase 1/2a

trial have been completed and one randomized Phase 2 trial is currently ongoing

in the US, UK and Europe. Early clinical efficacy data are highly encouraging,

and no serious toxicity or safety concerns have been reported to date. The

Oncoinvent team consists of approx. 40 employees and runs a state-of-the-art

manufacturing facility to produce drug products for clinical trials in Nydalen,

Oslo. Oncoinvent is listed on the Oslo Stock Exchange.

About Radspherin

Radspherin® is an investigational radiopharmaceutical designed for the local

treatment of cancer that has spread to body cavities. It consists of calcium

carbonate microparticles containing the radioactive material radium-224. The

mode of action is the decay of radium-224 emitting alpha-particles, a highly

potent form of ionizing radiation. Radspherin® is investigated in clinical

studies to treat peritoneal carcinomatoses from ovarian and colorectal cancer

and it is administered intraperitoneally after surgical resection with removal

of all macroscopic tumors.
