Targeted Radionuclide Therapy for Metastatic Melanoma [131I] ICF01012

Targeted Radionuclide Therapy for Metastatic Melanoma [131I] ICF01012: Phase I Study

This study is a phase I clinical trial aimed to determine the recommended dose of [131I]ICF01012 to administer for the treatment of patients with pigmented metastatic melanoma (binding [131I]ICF01012 ). The [131I]ICF01012 is a targeted radionuclide therapy with a high affinity for melanin.

This study will include a maximum of 36 patients. This study will begin with a preselection part that consists of an injection of [131I]ICF01012 at a diagnostic dose (185 MBq) in order to preselect patients who will receive the therapeutic dose according to the dosimetry results : binding of [131I]ICF01012 on at least a tumoral lesion and an acceptable radiation absorbed dose to major organs.

The second phase will consist of a therapeutic part with a single administration of [131I]ICF01012 at a therapeutic dose. This part is a dose escalation model (4 levels of therapeutic dose were tested)
