Radiopharm Theranostic doses first patient with 18F-RAD101 in Phase 2b study

Radiopharm Theranostic (RADX)s announced the dosing of the first patient in its U.S. Phase 2b imaging study of 18F-RAD101 in suspected recurrent brain metastasis. The U.S. multicenter, open-label, single arm Phase 2b clinical trial1 is evaluating the diagnostic performance of 18F-RAD101 in 30 individuals with confirmed recurrent brain metastases from solid tumors of different origins. The primary objective of the study is concordance between 18F-RAD101 positive lesions and those seen in conventional imaging in participants with suspected recurrent brain metastases. RAD101 is a novel imaging small molecule that targets fatty acid synthase, a multi-enzyme protein that catalyses fatty acid synthesis and is overexpressed in many solid tumors, including cerebral metastasis. Disruption of FASN activity allows for the accurate detection of cancer cells, representing a strongly viable target for the imaging of brain metastasis. Positive data from the Imperial College of London’s Phase 2a imaging trial of 18F-RAD101 in patients with brain metastases showed significant tumor uptake that was consistent with and independent from the tumor of origin.
