[F-18]siPSMA and [F-18]siTATE:
Ready to substitute Ga-68 Tracers ?
[F-18]siPSMA and [F-18]siTATE:
a pair of SiFA-based ligands ready to compete with the clinically established Ga-68 ligands.
F-18 is ready to compete with Ga-68
The development of theranostic radiohybrid PSMA inhibitors (rhPSMAs) by A.Wurzer and H.J.Wester at the Institute for Pharmaceutical Radiochemistry, Technical University Munich (TUM) and the subsequently clinical evaluation of [F-18]rhPSMAs by M. Eiber and colleagues at the Department of Nuclear Medicine (TUM) demonstrated for the very first time that an F-18-labeled silicone fluorine acceptor based radiopharmaceutical is stable against defluorination in-vivo and, if carefully designed, can show pharmacokinetics suitable for PET imaging even at early time points after injection. Due to the outstanding labeling and imaging characteristics, [F-18]rhPSMA are being clinically developed by Blueearth Diagnostics (UK). Based on this initial success story, a series of purely diagnostic [F-18]siPSMA inhibitors have been developed by the same group.
In addition, an automated process has been developed allowing to produce F-18-labeled SiFA-cinjugated radiopharmaceuticals in <1000sec (from end of bombardment to end of production/completed formulation). The process was established on a cassette system comprising of two stopcock manifolds.
Moreover, F-18-labeled SiFA-conjugated ocreotate, named [F-18]SiFAlin-TATE (siTATE), has been successfully compared with [Ga-68]DOTA-TOC in 13 patients with NET. The authors concluded that the favorable characteristics of [F-18]SiFAlin-TATE, the simple labeling procedure, and the promising clinical performance enable improved logistics and diagnostic possibilities for PET imaging of NET.
In summary, and taking into accout that additional SiFA-peptides are being currently evaluated, we can conclude that the number of clinically revevant, SiFA-based F-18-labeled peptide and peptide-like radiopharmaceuticals will rapidly grow. The ease of production of F-18-labeled SiFA-conjugated radiopharmaceuticals will make them enormously competitive. It seems that the time has come to take a close look whether and to what extend F-18 can substitute Ga-68 in the rapidly-growing field of theranostics.

Scintomics and 1717 Life Science Ventures Team up in the Joint Venture PENTIXAPHARM to Develop CXCR4-Targeted Theranostics
>> Scintomics GmbH and 1717 Life Science Ventures GmbH announced today to have signed an agreement to collaborate in the development of the theranostic pair PentixaFor / PentixaTher.
PentixaPharm GmbH, based in Würzburg, is committed to develop PentixaFor and PentixaTher as a theranostic radiopharmaceutical pair, specifically targeting the CXCR4-receptor expressed in most fast progressing diseases, particularly malignant cancers.
“We are delighted that in 1717 LSV we have found a strong partner with an outstanding expertise in the clinical development of precision oncologics. Taking the various recent and successful proof-of-concept studies with PentixaFor and PentixaTher in men into account, this joint venture creates optimal conditions for the effective and swift clinical development of this unrivalled and unique pair of theranostic drugs”, said Prof. Hans-Jürgen Wester, PhD, Founder of Scintomics and Chair for Pharmaceutical Radiochemistry at the Technical University of Munich (TUM), Germany.
“The introduction of 68Ga-PentixaFor may be regarded as a milestone for clinical PET imaging of CXCR4 expressing malignancies”, added Dr. Hakim Bouterfa Co-founder of 1717 LSV GmbH and CEO of PentixaPharm. “Now we will focus on the next major step to provide CXCR4-directed endoradiotherapy in prospective clinical trials.”
