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

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).

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)
