Pilot Study of 64Cu-DOTA Pembrolizumab (64CDP) in Patients Receiving Stereotactic Body Radiation Therapy (SBRT) for Oligo-Progressive Non-Small Cell Lung Cancer (NSCLC)
This phase I trial studies the safety and side effects of a new positron emission tomography (PET) imaging agent called 64Cu-DOTA-pembrolizumab to see how well it works in determining treatment response for patients with stage IV non-small cell lung cancer (NSCLC) already receiving pembrolizumab. 64Cu-DOTA-pembrolizumab consists of a monoclonal antibody, pembrolizumab, that binds to a protein called PD-1 that is expressed on tumor cells. PET scans can then visualize the tumor cells using 64Cu, a radioactive substance. 64Cu-DOTA-pembrolizumab PET scans may be safe and useful to doctors in telling the difference between tumors that are still growing and areas that are not growing in patients with stage IV NSCLC receiving pembrolizumab treatment.
