Radiopharmaceuticals are a combination of a radioactive isotope (radionuclide) with a targeting vector. Radionuclides emit particles of specific energies that can be used for tumor destruction (alpha, electrons) or for imaging (photons, positrons). The targeting vector acts as a carrier and determines localization and biodistribution.

Medpace Core Laboratories has both scientific expertise and clinical trial experience managing trials of radiopharmaceuticals: for example, with peptide receptor radionuclide therapy (PRRT) trials. In this case, the radioisotope is chelated to single domain antibody (sdAbs) fragments targeting the receptor expressed by the target cancer cells. Radiolabeled sdAbs bear beneficial properties for nuclear imaging and internal radiotherapies such as (i) efficient penetration of target tumors and tissues; (2) fast and very specific binding and (iii) rapid clearance from non-target organs and tissues. PRRT is a powerful and innovative technology allowing personalized medicine by the calculation of radiation dose on a patient-by-patient basis.

Scanner Calibration

Calibration of the imaging modalities helps to achieve reliable quantitative, semi-quantitative and qualitative results that can be used to assess disease status and dosimetry calculations. This is imperative to enable the use of in-vivo biomarkers as imaging endpoints. Ensuring consistency in multi-center clinical trials that involves imaging is crucial when imaging data is acquired in different settings and different types of instrumentation. Scanner calibration is important for verification that the imaging instrument are performing according to specifications. Medpace processes ensure accurate quantitative data from nuclear imaging that can be used with confidence to estimate, for example, organ and tumor radiation absorbed doses.


Dosimetry corresponds to the estimation of radiation absorbed doses to critical organs and tumors. It allows for the optimization of administered activity across the therapy while maximizing the absorbed dose to tumors and limiting the exposure of organs at risk.

Our team of experts is able to support the creation of the imaging protocol, guide the choice of imaging modalities, and determine the choice of sampling time points needed to optimize dosimetry calculations and reproducibility of results. Our scientists will customize the dosimetry methodology for the study protocol and provide solid estimates of the radiopharmaceutical biodistribution and radiation absorbed doses to tumor lesions and organs of interest.


In addition to dosimetry calculations, radiopharmaceutical trials often require the determination of pharmacokinetic parameters in blood, plasma, and urine from biological samples counted at different times after infusion.

Medpace Core Labs can provide guidance to the sites and manage the radioactive counts data collection and conversion for further non-compartmental PK analysis by Medpace Biostatistics.
