Trial Summary

What is the purpose of this trial?

Evaluation of myeloma disease burden is currently suboptimal. This limits treatment planning and evaluation of residual disease following treatment. 89Zr-DFO-daratumumab is a novel immunoPET tracer, designed to detect CD38 on myeloma cells and allow visualization of myeloma in a PET scanner. A phase I study of 89Zr-DFO-daratumumab demonstrated safety and successful visualization of myeloma with 89Zr-DFO-daratumumab. This will be a phase II study of 89Zr-DFO-daratumumab to evaluate potential clinical applications of this novel imaging agent.

Do I need to stop my current medications for the trial?

The trial protocol does not specify whether you need to stop taking your current medications.

What data supports the effectiveness of the drug 89Zr-daratumumab PET/CT for multiple myeloma?

Research shows that 89Zr-daratumumab PET/CT is effective in targeting CD38, a protein found on myeloma cells, allowing for precise imaging of multiple myeloma in both animal models and humans. This drug demonstrated high specificity and sensitivity in detecting myeloma tumors, making it a promising tool for imaging and potentially guiding treatment.12345

Is 89Zr-DFO-daratumumab safe for use in humans?

In a study involving 10 patients with multiple myeloma, 89Zr-DFO-daratumumab was found to be safe with acceptable radiation levels. The study showed that it could be used for imaging without significant safety concerns.12678

How does ImmunoPET imaging for multiple myeloma differ from other treatments?

ImmunoPET imaging for multiple myeloma is unique because it uses a radiolabeled antibody, 89Zr-DFO-daratumumab, to specifically target and visualize CD38, a protein found on myeloma cells, allowing for precise imaging of the disease. This approach differs from traditional treatments as it focuses on imaging rather than directly treating the cancer, providing a non-invasive method to monitor disease progression and response to therapy.124910

Treatment Details

Interventions

  • 89Zr-daratumumab PET/CT
Trial OverviewThe trial tests an imaging agent called 89Zr-DFO-daratumumab in a PET scanner to visualize myeloma cells. This phase II study aims to assess how well it works and its potential clinical uses after showing safety and effectiveness in an earlier phase I trial.
Participant Groups
1Treatment groups
Experimental Treatment
Group I: CD38-positive multiple myelomaExperimental Treatment1 Intervention
Patients with CD38 positive multiple myeloma with be enrolled. Patients will undergo pretreatment evaluation with standard of care diagnostic tests, as well as experimental 89Zr-daratumumab PET/CT. Patients will then undergo a course of standard of care therapy as defined by a medical oncologist. Following therapy, patients will repeat standard of care diagnostic tests, as well as experimental 89Zr-daratumumab PET/CT. Data analysis will be performed to evaluate 89Zr-daratumumab against standard of care diagnostic tests for the detection and localization of active disease before and after therapy.

Findings from Research

Daratumumab, a monoclonal antibody targeting CD38, shows high specificity and sensitivity in imaging multiple myeloma tumors using [89Zr]Zr-DFO-daratumumab PET/CT, effectively detecting tumors of various sizes.
The study demonstrated that [89Zr]Zr-DFO-daratumumab has a strong binding affinity to CD38+ myeloma cells, with a dissociation constant of 3.3 nM, indicating its potential for image-guided delivery of therapeutic radionuclides in treating multiple myeloma.
Preclinical Development of CD38-Targeted [89Zr]Zr-DFO-Daratumumab for Imaging Multiple Myeloma.Ghai, A., Maji, D., Cho, N., et al.[2022]
The study successfully developed 89Zr-DFO-daratumumab, a radiolabeled monoclonal antibody that targets CD38 on multiple myeloma cells, showing high radiochemical purity and specificity in preclinical models.
In a phase I trial with 10 patients, 89Zr-DFO-daratumumab was found to be safe and effective for immunologic PET imaging, allowing visualization of myeloma sites in the bone, which could improve disease burden assessment.
CD38-targeted Immuno-PET of Multiple Myeloma: From Xenograft Models to First-in-Human Imaging.Ulaner, GA., Sobol, NB., O'Donoghue, JA., et al.[2021]
In a study of 41 patients with multiple myeloma and amyloidosis treated with daratumumab, those in second-line therapy and with advanced amyloidosis showed high rates of durable responses, while advanced multiple myeloma patients had a low overall response rate of only 36%.
The study found that daratumumab's effectiveness was particularly poor in patients with extramedullary plasmacytomas, and the results suggest that daratumumab should be administered earlier in the treatment course for better outcomes.
Daratumumab resistance is frequent in advanced-stage multiple myeloma patients irrespective of CD38 expression and is related to dismal prognosis.Pick, M., Vainstein, V., Goldschmidt, N., et al.[2018]
