In-Human CXCR4 Imaging of Hematologic and Solid Tumors Using [68Ga]-Pentixafor-PET

February 4, 2026 updated by: Memorial Sloan Kettering Cancer Center

In-human CXCR4 Imaging of Hematologic and Solid Tumors Using [68Ga]-Pentixafor-PET

The purpose of this study is to determine the uptake of the imaging agent [68Ga]-pentixafor with PET/CT scans in people with monoclonal gammopathy of undetermined significance (MGUS), smoldering multiple myeloma (SMM), and non-Hodgkin lymphoma (NHL), or you have histiocytic neoplasms (Langerhans cell histiocytosis (LCH), Erdheim-Chester disease (ECD) and/or Rosai-Dorfman disease (RDD).

Description

Inclusion Criteria:

Twenty patients with histologically proven treatment-naïve, therapy-refractory or relapsed blood cancers meeting the below criteria will be included:

  • Indolent B- or T-cell Non-Hodgkin lymphoma (including cutaneous lymphomas) or Non-Hodgkin lymphoma with variable FDG uptake and clinical course, such as mantle cell lymphoma; and measurable disease according to Lugano criteria

or

  • Histiocytic neoplasms (Langerhans cell histiocytosis (LCH), Erdheim-Chester disease (ECD) and/or Rosai-Dorfman disease (RDD)
  • MGUS/SMM or MM according to IMWG definitions
  • Solid tumors, such as lung cancers, meningioma, adrenocortical neoplasms including cortisol-producing adenomas or high suspicion for tumor, such as in patients with Cushing's disease.
  • Age ≥18
  • Negative serum pregnancy test for female volunteers of childbearing age and potential (as defined by MSKCC Standards & Guidelines) from assays obtained <2 weeks prior to study enrollment/intervention; or negative urine pregnancy test performed on the day of intervention
  • MSKCC patients

Exclusion Criteria:

  • Breast-feeding
  • History of renal functional disorders (chronic kidney disease with eGFR<30)
  • Refusal or inability to tolerate the scanning procedure (e.g., due to claustrophobia)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: [68Ga]-Pentixafor
An intravenous bolus of 3 -5 mCi [68Ga]-Pentixafor will be injected in all participants that will be imaged on a hybrid PET/CT device. Any of the following factors may determine if imaging cannot be performed: tolerance/compliance in the PET/CT scanner; dose availability; dose quality control; availability of the PET/CT scanner or availability of study personnel. [68Ga]-Pentixafor uptake dynamics / pharmacokinetics will be evaluated by PET/CT performed with a low-dose CT component used for PET attenuation correction (1-2 mSv). [68Ga]-Pentixafor-PET/CT scan duration will be approximately 1.5 hours. Some patients will have two scans.
Drug: [68Ga]-Pentixafor
An intravenous bolus of 3 -5 mCi of [68Ga]-Pentixafor will be injected in all participants.
