Summary

This trial uses radiation therapy and a special PET scan to help lymphoma and metastatic solid tumor patients. The radiation attracts immune cells to fight the cancer, and the scan checks if these cells are working properly.

Who is the study for?

Adults (18+) with lymphoma or solid tumor malignancies suitable for radiation therapy, able to follow the trial's procedures. They must have stable treatment for 2 months prior and be willing to undergo daily PET scans post-radiation. Women of childbearing age need a negative pregnancy test and agree to use contraception.

What is being tested?

This phase I trial is testing how radiation affects immune cells in cancer patients by using a special PET scan tracer before and after radiation therapy. The goal is to see if this can help monitor immune response in patients getting CAR T-cell infusion or stereotactic body radiation therapy (SBRT).

What are the potential side effects?

Potential side effects are not detailed but may include reactions related to the CD8 PET tracer used for imaging, similar to those seen with other compounds of its class. Side effects from the radiation therapy itself could also occur.

Study Objectives

Study objectives can provide a clearer picture of what you can expect from a treatment.

Primary study objectives

Change in CD8 positron emission tomography (PET) maximum standardized uptake value (SUVmax)

Secondary study objectives

CD8 PET SUV (Subset)

Evaluation of tumor response (fludeoxyglucose F-18 [FDG] PET and/or computed tomography [CT]) as it relates to both baseline CD8 PET SUV and changes observed after SBRT.

Experimental Treatment

Group I: Basic science (zirconium Zr 89-Df-crefmirlimab, PET, SBRT)Experimental Treatment4 Interventions

Patients receive zirconium Zr 89-Df-crefmirlimab IV over 5-10 minutes and then under PET imaging 24 hours after infusion before and after SBRT. Patients undergo SBRT every 2-5 days for a total of 5 fractions. For lymphoma patients only, IMRT on consecutive days may be used.
