NCT05093335

Brief Summary

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).

Outcome Measures

Primary Outcomes (1)

  • Tumor standard uptake value (SUV)

    Means and 95% confidence intervals for \[68Ga\]-Pentixafor standardized uptake values (SUV) and tumor-to-background ratios (TBR) of tumors will be recorded. Uptake will be measured in tumors.

    1 year

Study Arms (1)

[68Ga]-Pentixafor

EXPERIMENTAL

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

Interventions

An intravenous bolus of 3 -5 mCi of \[68Ga\]-Pentixafor will be injected in all participants.

Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • 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
  • 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

You may not qualify if:

  • 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)
