Armacokinetic Tetraphenylporphyrin Epigenetics profile. Translation in two advanced BC patients, resulted in no negative effects, confirming prior observations on the biosafety of radiotracers depending on the potent GRPR-antagonist [DPhe6 ,LeuNHEt13 ]BBN(6-13) and on GRPR-antagonist radioligands normally. Moreover, it revealed the capability of [99m Tc]Tc-DB15 to detect a number of metastatic BC lesions, both inside the skeleton and in soft tissues, but these findings really need to be confirmed prospectively in a devoted human study. In view of the above, additional clinical evaluation seems to be warranted to establish the diagnostic worth of [99m Tc]Tc-DB15 in BC, Pc, as well as other GRPR-expressing human malignancies.Supplementary Materials: The following are offered on the web at https://www.mdpi.com/article/ 10.3390/cancers13205093/s1, Figure S1: Standard radiochromatogram of HPLC evaluation of [99m Tc]TcDB15 (preclinical); Figure S2: Typical radiochromatogram of HPLC evaluation of [99m Tc]Tc-DB15 (for patients); Figure S3: Entire physique 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 information for [99m Tc]Tc-DB15 in PC-3 xenograft-bearing SCID mice at 1, 4 and 24 h pi; Table S2: Numerical biodistribution information 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.; 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 and also the European Union (European Regional Development Fund) by means of the project “NCSRD–INRASTES analysis activities inside the framework on the national RIS3” (MIS 5002559), implemented beneath the “Action for the Strategic Development on the Study and Technological Sector”, funded by the Operational Program “Competitiveness, Entrepreneurship and Innovation” (NSRF 2014-2020). Additional support was supplied by Siemens AG through the project stablishing a Multidisciplinary and Productive Innovation and Entrepreneurship Hub(E-11928). The preparation on the radioligand for the patient study was supported by the CERAD project, financed under Sensible Growth Operational System 2014020, Priority IV, Measure four.two. POIR.04.02.004-A001/16. The clinical a part of the study obtained economic assistance in the Poznan University of Medical Sciences (grant No. 502-14-22213550-41147).
