FDA Accepts New Drug Application for Generic Lutetium Lu 177 Dotatate (177Lu-PNT2003) in GEP-NETs
Breaking News. We have generic somatostatin analogues, generic targeted therapy, and I guess it was only a matter of time until we got generic PRRT (Radioligand Therapy) e.g. generic Lutetium Lu 177 dotatate. This news begins that process which is also based on a clinical trial which took place in Canada (195 participants) and which now appears to be complete. The announcement comes from US but if this is realised, you can expect it to be available in many other countries and continents where there is a market. This may even drive down prices and/or increase availability. The FDA has…
Clinical Trial: Novel Somatostatin Receptor Subtype 2 Antagonist Labelled With Terbium-161 (161Tb-DOTA-LM3)
Update 14th December 2025 - Results from the Phase 0 proof of concept trial. Conclusion [161Tb]Tb-DOTA-LM3 shows a 7.6-fold-higher tumor absorbed dose than that found when using [177Lu]Lu-DOTATOC. The tumor–to–bone marrow absorbed dose ratio was in the same range for both radiopharmaceuticals. The promising dosimetry and safety results from this phase 0 study will lay the foundation for further clinical development of [161Tb]Tb-DOTA-LM3. Dose-escalation trials and peptide dose optimizing studies are warranted to establish the maximum tolerated activity per cycle and assess long-term efficacy. The integration of 161Tb into PRRT regimens has the potential to redefine the therapeutic landscape for NETs,…
Neuroendocrine Cancer – Exciting Times Ahead!
In the last 12-24 months, there seems to have been announcement after announcement of new and/or upgraded/enhanced diagnostics and treatment types for Neuroendocrine Cancer. Scans, radionuclide therapies, combination therapies, somatostatin analogues, biological therapies, etc. Some of the announcements are just expansions of existing therapies having been approved in new (but significant) regions. Compared to some other cancers, even those which hit the headlines often, we appear to be doing not too badly. However, the pressure needs to stay on, all patients need access to the best diagnostics and treatments for them; and at the requisite time. There's even more in the pipeline and I'm hoping…
PRRT and the NHS England Cancer Drugs Fund (now archived information)
Please note this post is now historic information - PRRT (Lutathera) was eventually approved for use in UK. See the following post for the very latest on PRRT worldwide - CLICK HERE I was extremely disappointed to learn of the decision to remove PRRT (Lutetium or Yttrium) from the Cancer Drugs Fund (CDF). You can read the detail of the decision here: CDF Statement. PRRT has regularly been described by NET specialists and patients as the "magic bullet" due to its potential to shrink or kill tumours. This is the second Neuroendocrine Cancer treatment to be withdrawn this year, after…
