Purpose

This phase of the protocol (protocol part B), seeks to evaluate the new formulation in healthy normal volunteers to confirm the new formulation provides comparable human dosimetry to which was seen and published in protocol part A. Additionally, the new formulation will be studied utilizing an expanded patient population to include patients with confirmed diagnosis of multiple myeloma (MM), low-grade lymphoma, or MM and lymphoma patients who are status post bone marrow transplant (BMT) with negative imaging and suspected recurrence.

documented bilateral oophorectomy and/or documented hysterectomy), post-menopausal

Intervention Model Description
For Cohort 1B, 6 healthy volunteers and 6 patients with either multiple myeloma (MM) or lymphoma will be recruited (healthy volunteers will be split equally with 3 men and 3 women enrolled, all efforts will be made to keep the number of subjects with MM and lymphoma enrolled equal to Cohort 1B but it will not be a requirement).

Arm Groups

ArmDescriptionAssigned Intervention
Experimental
Pilot/Cohort 1B: Dosimetry 64Cu-LLP2A
- Will be asked to undergo 64Cu-LLP2A-PET/CT imaging at up to three separate time points for purposes of calculating human dosimetry. Imaging time points will be dependent upon day of the week injection occurs: - Tuesday or Thursday injection: 0-60 minute multiple quick body scans + 120-180 min post injection body scan - Wednesday or Friday injection: 0-60 minute multiple quick body scans + 180-240 min post injection body scan - ALL PATIENTS: 15-28 hours post injection body scan on Wednesday (for Tuesday injection), Thursday (for Wednesday injection), Friday (for Thursday injection) or Saturday (for Friday injection)
  • Drug: 64Cu-LLP2A
    64Cu-LLP2A, will be manufactured following batch production record at the cyclotron GMP facility (Washington University School of Medicine GMP radiochemistry/cyclotron facility)
  • Device: PET/CT
    The results of 64Cu-LLP2A-PET/CT will not be provided to the patient or the treating oncologist/surgeon unless, in the judgment of the principal investigator, the images demonstrate an unsuspected abnormality that may warrant further evaluation.
Experimental
Cohort 2B: Quantitative 64Cu-LLP2A
- Will be asked to undergo dynamic PET/CT imaging centered over a known target lesion (as determined by other radiological imaging studies) beginning with 64Cu-LLP2A-PET/CT and continuing for a total of 60 minutes. An additional vertex to upper thigh body scan will be obtained between 60- and 180-minutes post injection or at the optimal imaging time point that was derived from cohort 1B.
  • Drug: 64Cu-LLP2A
    64Cu-LLP2A, will be manufactured following batch production record at the cyclotron GMP facility (Washington University School of Medicine GMP radiochemistry/cyclotron facility)
  • Device: PET/CT
    The results of 64Cu-LLP2A-PET/CT will not be provided to the patient or the treating oncologist/surgeon unless, in the judgment of the principal investigator, the images demonstrate an unsuspected abnormality that may warrant further evaluation.
