Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

NON_RANDOMIZED

Intervention Model

PARALLEL

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).
Primary Study Purpose

DIAGNOSTIC

Blinding Strategy

NONE

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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)

Group Type EXPERIMENTAL

64Cu-LLP2A

Intervention Type DRUG

64Cu-LLP2A, will be manufactured following batch production record at the cyclotron GMP facility (Washington University School of Medicine GMP radiochemistry/cyclotron facility)

PET/CT

Intervention Type DEVICE

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.

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.
