Early Phase I Evaluation of 64Cu-LLP2A for Imaging Hematologic Malignancies Part B

What this Trial Is About

Researchers are evaluating a new formulation of 64Cu-LLP2A, a drug used with PETCT imaging, to study its dosimetry and imaging quality in healthy volunteers and patients with certain blood cancers. These cancers include multiple myeloma and various low-grade lymphomas. This early phase 1 study aims to confirm that the new formulation provides similar human dosimetry to previously published results and to expand evaluation to patients with confirmed diagnoses or those post bone marrow transplant with suspected recurrence. Participants will receive 64Cu-LLP2A followed by PETCT imaging at up to three separate times depending on the injection day of the week. Imaging sessions involve multiple quick body scans within the first hour, additional scans between 120 to 240 minutes, and a later scan 15 to 28 hours post injection. Patients with known lesions will have dynamic imaging centered over those areas for one hour, plus an additional scan from head to upper thigh after injection. During the study, participants will undergo PETCT scans and monitoring of organ dosimetry and safety for up to seven days after 64Cu-LLP2A administration. Researchers will assess the quality of PET images by looking at bone marrow uptake and tumor-to-background ratios. Safety will be tracked by recording any adverse events. The total imaging and evaluation period is estimated to last up to two days, with additional follow-up phone assessments.
