Immune checkpoint inhibitors and Carbon iON radiotherapy In solid Cancers with stable disease (ICONIC)

ICONIC is a multicenter, open-label, nonrandomized, phase II clinical trial aiming to evaluate the feasibility and clinical activity of the addition of carbon ion radiotherapy to immune checkpoint inhibitors in cancer patients who have obtained disease stability with pembrolizumab administered as per standard-of-care. Considering that no clinical trials have been conducted thus far to assess the safety of the association between immune checkpoint inhibitors and carbon ion radiotherapy, the current clinical study will provide controlled data about the safety of this unprecedented therapeutic combination. Clinical Trial Registration: NCT05229614 (ClinicalTrials.gov).
