Ebrahim S Delpassand, Izabela Tworowska, Rouzbeh Esfandiari, Julien Torgue, Jason Hurt, Afshin Shafie and Rodolfo Núñez Journal of Nuclear Medicine, January 2022, jnumed.121.263230; DOI: https://doi.org/10.2967/jnumed.121.263230 Trial SummaryAlphaMedix™ (²¹²Pb-DOTAMTATE) is a radiotherapeutic drug indicated in subjects with unresectable, metastatic somatostatin receptor (SSTR) positive neuroendocrine tumors (NETs). Because 212Pb is an in vivo generator of alpha particles, it is particularly suitable for SSTR therapy applications, i.e. it's a type of PRRT. This drug addresses an unmet need in the field of peptide receptor radionuclide therapy (PRRT) for NETs. Substitution of an alpha emitter (²¹²Pb) for the beta emitters currently being used (i.e., 177Lu or 90Y) will provide significantly higher Linear Energy Transfer (LET) and a shorter path length. Higher LET particles should cause more tumor cell death. A shorter path length should result in less collateral damage to the normal tissue and therefore fewer…

Detectnet™ (64Cu-DOTATATE) – an expansion of the Somatostatin Receptor PET Imaging for Neuroendocrine Cancer

Clinical Trials, Living with Neuroendocrine Cancer, Treatment
Edit 21st January 2021.  The imaging time window of 64Cu-DOTATATE positron emission tomography/computed tomography (PET/CT) for patients with neuroendocrine neoplasms can be expanded from one hour to three hours post-injection, according to new research published in the January 2021 issue of The Journal of Nuclear Medicine.  Read more here Edit 4th September 2020.  64Cu-dotatate now named Detectnet™ is approved for use by US FDA. Majority read revealed Detectnet had over 98% accuracy, 100% sensitivity, and over 96% specificity to confirm or exclude presence of disease. Read more here.  Edit 14th July 2020.  Expanded Access Program via clinical trial now recruiting - see below.  The objective of this trial is to provide patients with confirmed or suspicion of NET access to Copper Cu 64 Dotatate for the detection, localization, and monitoring of…

Targeted Alpha-emitter Therapy (TAT) – the wave of the future in nuclear oncology/PRRT?

Targeted Alpha-emitter Therapy (TAT) – the wave of the future in nuclear oncology/PRRT?

Clinical Trials
What is Targeted Alpha-emitter Therapy?Regular PRRT which is authorised for use now, i.e. Lutathera/Lu177 is a beta therapy.  Targeted Alpha Therapy is based on the coupling of alpha particle emitting radioisotopes to tumour selective carrier molecules, such as monoclonal antibodies or peptides. These molecules have the ability to selectively target tumour cells even if they are spread throughout the body. They recognize the targeted cancer cells through antigens that are expressed on the cell surface and can bind selectively to these cells, similar a key fitting into a lock. In targeted alpha therapy these carrier molecules serve as vehicles to transport the radioisotopes to the cancer cells. This is called the "magic bullet" approach. Radioisotopes that emit alpha particles seem particularly promising to selectively destroy cancer cells. Alpha particles have…
