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 revealed the potential of [99m Tc]Tc-DB15 to detect many metastatic BC lesions, both inside the skeleton and in soft tissues, but these findings have to be confirmed prospectively inside a committed human study. In view in the above, additional clinical evaluation appears to become warranted to establish the diagnostic value of [99m Tc]Tc-DB15 in BC, Computer, and also other GRPR-expressing human malignancies.Supplementary Components: The following are available on line at https://www.mdpi.com/article/ 10.3390/cancers13205093/s1, Figure S1: Standard 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: Entire 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 information 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.; resources, 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.; 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 Development Fund) by means of the project “NCSRD–INRASTES research activities in the framework of the national RIS3” (MIS 5002559), implemented under the “Action for the Strategic Improvement around the Investigation and Technological Sector”, funded by the Operational Plan “Competitiveness, Entrepreneurship and Innovation” (NSRF 2014-2020). Additional help was provided by Siemens AG via the project stablishing a Multidisciplinary and Effective Innovation and Entrepreneurship Hub(Rhod-2 AM Technical Information E-11928). The preparation of your radioligand for the patient study was supported by the CERAD project, financed below Quizartinib Protocol Sensible Development Operational Program 2014020, Priority IV, Measure four.2. POIR.04.02.004-A001/16. The clinical part of the study obtained economic support from the Poznan University of Healthcare Sciences (grant No. 502-14-22213550-41147). Institutional Critique Board Statement: The animal and patient studies have been performed according to the recommendations on the Declaration of Helsinki. The animal protocols were authorized by the Department of Agriculture and Veterinary Service of your Prefecture of Athens (protocol numbers #1609 for the stability and #1610 for the biodistribution research, both issued on 11 April 2018).
