Radspherin is a novel alpha-radiation therapy designed for targeted, direct treatment of cancers that have spread to body cavities. The Phase 2 is a randomised, open label, multicentre trial (NCT06504147) assessing the efficacy and safety of Radspherin in patients with peritoneal metastases from ovarian cancer following complete surgical resection and pre-operative chemotherapy.

The initial safety lead-in is designed to evaluate the safety and tolerability of Radspherin at the recommended dose of 7 MBq in the trial population before expanding to enrollment in the randomized part of the trial.

"The completion of patient recruitment in the safety lead-in marks an important milestone in the advancement of our Phase 2 trial," said Oystein Soug, CEO of Oncoinvent. "We are encouraged by being able to recruit patients and ship Radspherin to centers in the US, UK, EU as well as Norway in this trial. We will now analyze the safety data, announce the findings during March and we subsequently expect to move ahead with full trial enrollment. This milestone further reinforces our commitment to developing Radspherin as a promising treatment option for patients with peritoneal carcinomatosis."
