Armacokinetic profile. Translation in two sophisticated BC sufferers, resulted in no side effects, confirming preceding observations around the biosafety of radiotracers determined by the potent GRPR-antagonist [DPhe6 ,LeuNHEt13 ]BBN(6-13) and on GRPR-antagonist radioligands in general. Additionally, it Deoxythymidine-5′-triphosphate Protocol revealed the capability of [99m Tc]Tc-DB15 to detect numerous metastatic BC lesions, both inside the skeleton and in soft tissues, but these findings have to be confirmed prospectively in a committed human study. In view of the above, further clinical evaluation appears to become 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 readily available on-line at https://www.mdpi.com/article/ ten.3390/cancers13205093/s1, Figure S1: Typical radiochromatogram of HPLC evaluation of [99m Tc]TcDB15 (preclinical); Figure S2: Typical radiochromatogram of HPLC analysis of [99m Tc]Tc-DB15 (for patients); Figure S3: Complete physique scan 3 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, 4 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.; information 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.; ��-Tocopherol Technical Information funding acquisition, R.M., R.C. and T.M.

Funding: The preclinical study was co-financed by Greece as well as the European Union (European Regional Improvement Fund) through the project “NCSRD–INRASTES research activities inside the framework in the national RIS3” (MIS 5002559), implemented below the “Action for the Strategic Development on the Investigation and Technological Sector”, funded by the Operational System “Competitiveness, Entrepreneurship and Innovation” (NSRF 2014-2020). Additional assistance was provided by Siemens AG by way of the project stablishing a Multidisciplinary and Efficient Innovation and Entrepreneurship Hub(E-11928). The preparation from the radioligand for the patient study was supported by the CERAD project, financed under Clever Growth Operational Plan 2014020, Priority IV, Measure 4.two. POIR.04.02.004-A001/16. The clinical part of the study obtained financial support from the Poznan University of Healthcare Sciences (grant No. 502-14-22213550-41147). Institutional Review Board Statement: The animal and patient research had been performed according to the recommendations in the Declaration of Helsinki. The animal protocols were approved by the Division of Agriculture and Veterinary Service from the Prefecture of Athens (protocol numbers #1609 for the stability and #1610 for the biodistribution studies, both issued on 11 April 2018). The patient study protocol was authorized by the Bioethical Committee from the Poznan University of Health-related Sciences (selection no. 1153 issued on 16 January 2020).
