A Study of CD8+ T Cell Imaging During Treatment in People With Non-Small Cell Lung Cancer

August 25, 2026 updated by: Memorial Sloan Kettering Cancer Center

Assessment of Patients Immune Response After Treatment With Engineered Tumor Infiltrating Lymphocyte Therapy Incorporating CD8 PET Imaging

The purpose of this study to learn whether PET/CT (positron emission tomography/computed tomography) scans using an imaging agent (radiotracer) called zirconium Zr 89 crefmirlimab berdoxam is a safe and effective way to identify CD8+ T cells

Design Details

  • Primary Purpose: Diagnostic
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Participants with Metastatic non-small cell lung cancer (NSCLC)
Participants will have a diagnosis of metastatic non-small cell lung cancer (NSCLC)
Drug: Zirconium Zr 89 crefmirlimab berdoxam
Zirconium Zr 89 crefmirlimab berdoxam, the investigational agent proposed in this imaging study, is an anti-CD8 minibody (crefmirlimab), conjugated with deferoxamine (Df, berdoxam) and radiolabeled with Zirconium-89.
Diagnostic test: PET/CT Scan
Each patient will undergo up to four infusions of Zirconium Zr 89 crefmirlimab berdoxam followed by PET/CT 24 hours later (+/- 3 hours).

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Difference between Zirconium Zr 89 crefmirlimab berdoxam PET uptake at pre- vs post-TIL infusion and pre- vs post-ACZ redosing.
Time Frame: Baseline to two weeks
Assess the distribution of the CD8+ cells during TIL therapy by measuring the largest difference in Zirconium Zr 89 crefmirlimab berdoxam PET uptake at pre- vs post-TIL infusion and pre- vs post-ACZ redosing.
Baseline to two weeks
