Drug Information available for: Daratumumab

Arm Intervention/treatment
Experimental: 89Zr-daratumumab

Three patients will be administered 2 mCi of 89Zr-daratumumab in a total of 50 mg of daratumumab antibody. Administered activity (1 to 5 mCi) of radioactivity and total amount of administered antibody (3 to 50 mg) will be adjusted in subsequent patients in order to maximize image quality.

Patients in phase I will have up to 4 PET/CT scans, multiple blood draws, whole-body counts, and safety monitoring to determine pharmacokinetics, radiation dosimetry, and safety of 89Zr-DFO-daratumumab for PET/CT imaging. Phase II (total of 21-24 patients). After pharmacokinetics and radiation dosimetry are determined in phase I, additional patients will be enrolled in phase II.

Drug: 89Zr-daratumumab
2 mCi of 89Zr-daratumumab will be administered on day 0.

Device: PET/CT scans
PET/CT images will be obtained on post-administration days 1, 2-4, 5-6, and/or 7-8 following administration of 89Zr-DFO-daratumumab to determine the optimal time point for imaging.

Other: Blood draws
Blood and serum samples will be weighed and counted in a scintillation well counter calibrated for 89Zr. Immediately before or after each PET/CT imaging session,

Primary Outcome Measures :
  1. Average Absorbed Radiation Dose Estimates for Normal Tissues for Phase I Participants [ Time Frame: up to 19 months ]
    Standardized uptake value (SUV) in various organs will be estimated from VOI analysis of clinical images and converted to activity-time curves. The areas under the activity-time curves will be derived by integration, converted to residence times, and used as input to the OLINDA/EXM dosimetry program to obtain absorbed dose estimates for normal tissues for all Phase I participants, regardless of study dose. Each participant underwent four PET/CT scans over the next 8 days, as well as blood chemistry and whole-body counts, to determine safety, tracer biodistribution, pharmacokinetics, and radiation dosimetry. Because 89Zr has a half-life of 78 hours, only a single administration of tracer was needed to obtain all four PET/CT scans for all Phase I participants. Results were combined because all received the same dose of tracer.
