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. In addition to the currently finalized
phase 1/2a trial in colorectal cancer, one phase 1 trial and one randomized
phase 2 trial, both in ovarian cancer, are ongoing in the US, UK and Europe.
Preliminary clinical efficacy data are highly encouraging, and no serious
toxicity or safety concerns have been reported to date. The experienced
Oncoinvent team runs a state-of-the-art manufacturing facility to produce drug
products for clinical trials in Nydalen, Oslo. Oncoinvent is listed on the
Euronext Growth Oslo.

About Radspherin
Radspherin® is an investigational radiopharmaceutical designed for the local
treatment of cancer that has spread to body cavities. It consists of billions 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 ongoing
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.
