Alpha-emitter PRRT: A Phase 2 Open Label Study to Evaluate the Safety and Effectiveness of 212Pb-DOTAMTATE in PRRT Naive Subjects With SSTR Expressing NET

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 Update 16th May 2023. Trial’s Objective Response Rate Endpoint Already Achieved. RadioMedix and Orano Med, two clinical stage radiopharmaceutical companies, today announced that the last patient has been dosed in the Phase II trial of the targeted alpha emitter therapy, 212Pb-DOTAMTATE (AlphaMedix™). This trial is being conducted to evaluate the safety and effectiveness of AlphaMedix™ in peptide receptor radionuclide therapy (PRRT) of naive patients with somatostatin receptor-expressing neuroendocrine tumors (NET), regardless of the location of the primary tumor. Top-line data from the trial is expected in mid-2024. Remarkably, based on data already collected, the objective response rate (ORR) endpoint has already been achieved and is more than twice as high as the current standard of care. Read more hereWhat…

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?

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…
