Study Summary

This phase I trial tests the safety of \[89Zr\]DFO-YS5 positron emission tomography (PET) imaging and how well it works to detect CD46 positive cancer cells in patients with multiple myeloma. \[89Zr\]DFO-YS5 is an imaging agent called a radiopharmaceutical tracer. A radiopharmaceutical tracer uses a small amount of radioactive material that is injected into a vein to help image different areas of the body. \[89Zr\]DFO-YS5 targets a specialized protein called CD46, which is in certain multiple myeloma cancer cells, and \[89Zr\]DFO-YS5 PET scans may improve detection of multiple myeloma.

Primary Outcome

Defined as the rate of lesions with positive uptake when compared against 18F-fluorodeoxyglucose (FDG) PET/computed tomography (CT) positivity. Sensitivity estimated based on lesion level without considering the location of the lesions or the possible intracorrelation of the lesions from the same patient by point estimate with its 95% confidence interval.
