A Safety and Biodistribution Study of [I-124]-CPD-1028 Injection in Solid Tumours

A single intravenous dose of \[I-124\]-CPD-1028 Injection will be given at Visit 2 (within 21 days of screening Visit 1), and may be followed by whole body PET/CT imaging approximately 3 hours post-injection. PET/CT imaging will occur at Visit 3 (2-3 days after Visit 2) and Visit 4 (5-7 days after Visit 2). PET/CT imaging may also occur at Visit 5 (16-18 days after Visit 2). Visit 6 (28 +/- 2 days after Visit 2) is a follow-up telephone call for a post-treatment safety assessment. At Visits 2-5, whole body biodistribution and tumour uptake will be assessed. At all visits, safety will be assessed.

\[Optional\] An intravenous dose of 0.4, 1.4 or 6 mg/kg of body weight of CPD-1061 may be given 1-2 hours prior to injection of \[I-124\]-CPD-1028 at Visit 2. The decision to use CPD-1061 and the dose amount is based on an adaptive design and is dependent on interim reviews of imaging data.
