Imaging Study of [89Zr]DFO-YS5 for Detecting CD46 Positive Malignancy in Multiple Myeloma

Is NCT05892393 recruiting? Yes, currently enrolling (Sep 2026). This Phase 1 trial studies Zirconium Zr 89-DFO-YS5 for multiple myeloma.

Phase 1RecruitingRobert Flavell, MD, PhDNCT05892393Data as of Sep 2026

Treatment: Zirconium Zr 89-DFO-YS5This 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.

Biomarker criteria

Required: CD46 expression (testing required; no eligibility threshold specified)

Imaging Study of [89Zr]DFO-YS5 for Detecting CD46 Positive Malignancy in Multiple Myeloma

Required: FDG positive (uptake greater than liver on FDG PET)

At least one positive myelomatous lesion found on 18F-FDG PET/CT or PET/MRI. A positive lesion is defined as uptake greater than liver on FDG PET, based on the Italian myeloma criteria for PET use (IMPeTUs) criteria
