Drug Description
This is an open-label, single dose, single arm, multicenter Phase 2b study to establish the imaging performance of RAD101 PET in participants who are ≥ 18 years of age and with suspected recurrent brain metastases from solid tumors. The study consists of a 4-week Screening Period, a 3-day Imaging and Safety Follow-Up Period, and a Data Collection Period of up to 6 months. Participant eligibility will be determined during the Screening Period and eligible participants will be enrolled in the study. On Day 1, the enrolled participants will receive a single dose of the investigational medicinal product (IMP), RAD101. Participants will then proceed with a whole brain PET scan. A high-resolution Magnetic Resonance Imaging (MRI) will be performed in joint acquisition with PET or separately on the same day, or on the day prior to or the day following RAD101 administration. For applicable study sites where PK samples will be collected, whole body PET scans will be performed, blood samples will be drawn, and urine will be collected throughout the scanning period. A phone follow-up will be performed on Day 3 (+ 1 day). Participants will have follow-up (longitudinal) MRI (otherwise CT) scans (longitudinal imaging) and/ or a biopsy according to their Standard of Care (SoC). The longitudinal image results, and details of the biopsy if performed as part of SoC (i.e., location and histopathology results), will be collected during the 6- month Data Collection Period.

Reasoning

At 51%, the market ignores March 2026 interim data showing RAD101 already met the primary endpoint with 90% concordance in 20 of 30 patients. The final results are overwhelmingly likely to be positive. Buying max YES.
