Imaging Study of [89Zr]DFO-YS5 for Detecting CD46 Positive Malignancy in Multiple Myeloma
Recruiting now · Phase 1
Conditions studied: Multiple Myeloma, Plasma Cell Myeloma
In brief
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.

Who can join
Age: 18 and older. Sex: any. Healthy volunteers: not accepted.
You may qualify if…
- Participants must have histologically or cytologically confirmed multiple myeloma by International Myeloma Working Group (IMWG) diagnostic criteria
- 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
- Age >= 18 years
- Total bilirubin =< 1.5 X institutional upper limit of normal (ULN)
- Aspartate aminotransferase (AST) =< 3 X ULN
- Alanine aminotransferase (ALT) =< 3 X ULN
- Creatinine clearance >= 30 mL/min, calculated using the Cockcroft-Gault equation or serum creatinine <= 1.5x the institutional upper limit of normal.
- Ability to understand a written informed consent document, and the willingness to sign it
You may not qualify if…
- Any condition that, in the opinion of the principal investigator, would impair the participants' ability to comply with study procedures or interfere with the safety of the investigational regimen
- Individuals who are pregnant or breastfeeding/chestfeeding.
- - Breast-feeding/chest-feeding should be discontinued before administration of [89ZR]DFO-YS5.
- Females of childbearing potential must have a negative urine or serum pregnancy test (i.e., human chorionic gonadotropin test) within 72 hours prior to administration of [89ZR]-DFO-YS5.
- - If the urine pregnancy test is positive or equivocal, a confirmatory serum pregnancy test is required. In such cases, the individual must be excluded from participation if the serum pregnancy result is positive.
- - A female is considered to be of childbearing potential (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice), unless it is documented that the individual meets either of the following two criteria: (1) has reached a postmenopausal state ( >= 12 continuous months of amenorrhea with no identified cause other than menopause); or (2) has undergone surgical sterilization (i.e., hysterectomy and/or bilateral oophorectomy for removal of uterus and/or ovaries).
- Individuals who are pregnant or breastfeeding/chestfeeding are excluded because there is an unknown but potential risk for adverse effects in the unborn/nursing child secondary to treatment of the study participant with [89ZR]-DFO-YS5
