Armacokinetic profile. Translation in two advanced BC patients, resulted in no unwanted side effects, confirming preceding observations on the biosafety of radiotracers based on the potent GRPR-antagonist [DPhe6 ,LeuNHEt13 ]BBN(6-13) and on GRPR-antagonist radioligands generally. In addition, it revealed the capacity of [99m Tc]Tc-DB15 to detect numerous metastatic BC lesions, each in the skeleton and in soft tissues, but these findings need to be confirmed prospectively within a devoted human study. In view in the above, additional clinical evaluation seems to be warranted to establish the diagnostic worth of [99m Tc]Tc-DB15 in BC, Computer, as well as other GRPR-expressing human malignancies.Supplementary Supplies: The following are obtainable online at https://www.mdpi.com/article/ ten.3390/cancers13205093/s1, Figure S1: Typical radiochromatogram of HPLC analysis of [99m Tc]TcDB15 (preclinical); Figure S2: Common radiochromatogram of HPLC analysis of [99m Tc]Tc-DB15 (for individuals); Figure S3: Whole body scan three h pi of [99m Tc]Tc-DB15 in patient 1 (with anterior and posterior projection); Figure S4: PET/CT 1 h pi of [18 F]FDG in patient 1; Table S1: Numerical biodistribution data for [99m Tc]Tc-DB15 in PC-3 xenograft-bearing SCID mice at 1, four and 24 h pi; Table S2: Numerical biodistribution data for [99m Tc]Tc-DB15 in T-47D xenograft-bearing SCID mice at 1, four and 24 h pi.Cancers 2021, 13,12 ofAuthor Contributions: Conceptualization, B.A.N., R.M. and T.M.; methodology, B.A.N., A.K., P.K., B.J., B.B., D.I. and T.M.; validation, B.A.N., R.M., R.C., D.I. and T.M.; investigation, B.A.N., A.K., P.K., B.J., B.B., R.C., D.I. and T.M.; sources, R.M., R.C. and T.M.; data curation, P.K., R.M., R.C. and T.M.; writing–original draft preparation, T.M.; writing–review and editing, all co-authors; supervision, B.A.N., R.M., R.C. and T.M.; project administration, R.M., R.C. and T.M.; funding acquisition, R.M., R.C. and T.M.

Funding: The preclinical study was co-financed by Greece plus the European Union (European Regional Development Fund) by way of the project “NCSRD–INRASTES analysis activities in the framework of your national RIS3” (MIS 5002559), implemented under the “Action for the Strategic Development on the Compound Library CAS Investigation and Technological Sector”, funded by the (-)-Blebbistatin Inhibitor Operational System “Competitiveness, Entrepreneurship and Innovation” (NSRF 2014-2020). Additional support was provided by Siemens AG by way of the project stablishing a Multidisciplinary and Effective Innovation and Entrepreneurship Hub(E-11928). The preparation with the radioligand for the patient study was supported by the CERAD project, financed beneath Clever Development Operational System 2014020, Priority IV, Measure 4.2.
