Brief summary

The aim of this study is assessing the safety and tolerability of a single administration of an experimental radiotracer 99mTc-3BP-4961 (Investigational product or IP) and then perform a single photon emission computed tomography (SPECT) scan. Who is it for? You may be eligible for this study if you are male or female over 18 years of age, presenting with clinical suspicion of active cancer during investigation for a possible new cancer diagnosis profession in a patient with know solid tumour. Study details Participants will receive a single IP intravenous administration of 10-15MBq /Kg of 99mTc-3BP-4961 but not more than 1200 MBq total. Participants will then be scanned using SPECT and CT for cancer lesion. After completion of the intervention, participants will be assessed for safety and tolerability using laboratory parameters and observation of adverse events. It is hoped that findings from this study will help further investigation for histopathological confirmation or tumour presence or tumour recurrence. Note: this brief summary is intended for lay audience.

Interventions

Single Investigational Product (IP) intravenous administration of 10-15 MBq /Kg of 99mTc-3BP-4961 but not more than 1200 MBq total based on the participant's weight. Adherence to intervention will be assessed via laboratory tests and compiling of forms for determination of adverse events
