About

The purpose of this early feasibility study was to investigate the pharmacokinetics of MP-3180 administered in rising doses and to evaluate the use of the Optical Renal Function Monitor (ORFM), an investigational noninvasive fluorescence detection device.

Full description

This was an open-label, rising single-dose study to investigate the pharmacokinetics of the investigational agent, MP-3180, and to evaluate the use of the Optical Renal Function Monitor (ORFM), an investigational noninvasive fluorescence detection device. Single-dose pharmacokinetics at four dose levels were evaluated following the administration of a single, intravenous dose of MP-3180. Iohexol was also administered followed by saline. Prior to administration of MP-3180 and iohexol, ORFM sensor probes were affixed to four locations on the body of each participant. The noninvasive fluorescent signal from MP-3180 was measured using the ORFM investigational device continuously for approximately four hours post MP-3180 administration. For the determination of the pharmacokinetic disposition of MP-3180 and iohexol, blood samples were collected from each participant provided the individual completed all blood collections in the study. The pharmacokinetics of MP-3180 and iohexol were assessed by statistical comparison of pharmacokinetic parameters derived from plasma concentration-time curves and urine recovery data.

Exclusion criteria

  1. Institutionalized participants will not be used

  2. History of any significant cardiovascular disease, renal, pulmonary, hematologic, endocrine, immunologic, dermatologic, neurologic (including any history of seizure disorder), psychological, musculoskeletal disease or malignancies unless deemed not clinically significant by the Principal Investigator or Medical Sub-Investigator.
