A Diagnostic Imaging Study of 64Cu-SARTATE™ for Neuroendocrine Tumours
UPDATE 6th June 2025. (Originally published Apr 2021). We probably all should start to use the term "Somatostatin Receptor PET" (SSTR PET) a lot more. We got used to using the shortened term Ga68 PET but since then we have an approved copper version known as 64Cu Dotatate (commercial brand name in US DETECTNET™). Now there are plenty others with potential to enter the supply chain. Here is one of them. DISCO topline results: 64Cu-SARTATE is highly effective in detecting tumours in NET patients compared to SOC imaging. Phase III planning underway.64Cu-SARTATE lesion detection substantially outperformed that of 68Ga-DOTATATE. 64Cu-SARTATE detected 393 to…
Neuroendocrine Tumours – now you see them, now you don’t!
In my post entitled "If you can see it, you can detect it", I listed the different types of scanning techniques and technology to find evidence of disease in Neuroendocrine Tumours (NETs). Of course, while scans, blood and (current) marker tests can give some pretty big and important clues, "tissue is the issue" that is most efficientEven after formal diagnosis, seeing all the tumours can be a challenge with NETs. In the article I quoted above, I indicated that scans for NETs can be analogous to picking 'horses for courses'. For example, most NETs have somatostatin receptors and can often…

A spotlight on Grade 3 (High grade) Neuroendocrine Neoplasms
Reviewed and updated 26th June 2024High Grade Neuroendocrine Neoplasms - the forgotten patient group?When reading articles in the mainstream media, found in medical publications; and even listening to doctors speak about my disease, it's clear that the focus is on the term "Neuroendocrine Tumours" or NET for short. Many websites of advocate foundation organisations and specialist scientific organisations, all still use the term "NET" in their naming. I too am guilty of having a large Facebook site falling into this category. It's little wonder that those with high grade disease can often feel like the forgotten patient group. Clearly all…

Understanding your Somatostatin Receptor (SSTR) PET/CT Scan Results
BackgroundIn my online patient group, there is constant discussion about the meaning of both pictures and words on scan reports. The one that seems to cause the most confusion is PET scans, mainly somatostatin receptor (SSTR) PETs such as Ga68 and Cu64 variants. Worth adding that it's the addition of a nuclear tracer that makes PETs seem different. Generally speaking, the PET hardware is essentially the same. Most have a built-in CT scan, much less frequently an MRI scan.Confusion is often triggered by healthcare system processes where the patient receives the report before the appointment to discuss the results with…
Somatostatin Receptors
Don't understand Somatostatin Receptors? Join the club! I got my head around the term 'Somatostatin' and 'Somatostatin Analogues' some time ago but the term 'Somatostatin Receptor' (SSTR) is still a bit of a mystery. SSTRs do come up in conversation quite often and I'm fed up of nodding sagely hoping it will eventually become clear! On analysis it looks like a technical subject - and therefore a challenge.I've taken a logical approach working from 'Somatostatin' to 'Somatostatin Analogue' before commencing on the 'receptor' bit. It is intentionally brief and (hopefully) simplistic!SomatostatinIt's important to understand this hormone and then why your…
Sequencing of Somatostatin-Receptor–Based Therapies in Neuroendocrine Tumor Patients
There can be no doubt that the discovery of somatostatin receptors as a means to treat Neuroendocrine Tumours has been a huge success. Additionally, scientists looked at a theranostic angle and provided somatostatin receptor based imaging for diagnosis and surveillance purposes. Many patients are prescribed somatostatin anlaogues shortly after diagnosis and this has led to a reduction in the morbidity that comes from active carcinoid syndrome and has reduced the incidence of carcinoid heart disease. More recently, the introduction of somatostatin receptor based PETs, taking over from the elderly Octreotide scans, has meant speedier and higher quality identification of NETs…
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…

Somatostatin Receptor Positive Advanced Bronchial Neuroendocrine Tumors – PRRT vs Everolimus
US Trial I was delighted to see this clinical trial which looks at the efficacy of PRRT (Lu177 dotatate) vs the efficacy of Everolimus (Afinitor). The latter is approved for the treatment of adult patients with progressive, well-differentiated non-functional, neuroendocrine tumors (NET) of gastrointestinal (GI) or lung origin with unresectable, locally advanced or metastatic disease (US FDA wording, Europe is similar). What is this trial? This phase II trial studies the effect of lutetium Lu 177 dotatate compared to the usual treatment (everolimus) in treating patients with somatostatin receptor positive bronchial neuroendocrine tumors that have spread to other places in…
Imaging to Monitor Treatment Response in Patients With Advanced Neuroendocrine Tumors
Another episode in the expert opinion series. I thought this might be useful for some of you after an interesting 'google alert' brought up these discussions. It comprises a roundtable discussion with known NET specialists and some big hitters too. "Dr Thor" is a favourite of mine. Worth pointing out that Dr Thor is giving is own view on this and that view may not be the same as your own doctor and/or hospital in terms of frequency and type of imaging devices used. Nonetheless, his opinions are always interesting. Also, worth pointing out this is based on "advanced" NETs,…
Neuroendocrine Cancer Clinical Trial – Lutetium-177Lu (Satoreotide)
What is Satoreotide?It's an agonist treatment. i.e. a 'next generation' radiologand for Peptide receptor radionuclide therapy (PRRT) or more specifically the radiopharmaceutical that binds to both activated and unactivated somatostatin receptors which are upregulated on these tumours. There is far higher binding via this mechanism than standard octreotate. The technical name of the radiopharmaceutical is Satoreotide tetraxetan lutetium-177 (author's note, I'm guessing but it could be a variant of Lanreotide).Somatostatin type 2 (SST2) receptor is overexpressed in many around 80% of NETs, some NEC and in certain hard-to-treat cancers such as small cell lung cancer (SCLC) and neuroblastoma, an aggressive,…
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,…
Nuclidium wins award to study NET radiopharmaceutical – Phase 1 Clinical Trial of TraceNET (TM)
What is TraceNETTM TraceNETTM is a a novel copper-based 'radiodiagnostic' for detecting neuroendocrine tumours (NET). The PET imaging agent candidate is the diagnostic component of NUCLIDIUM’s theranostic program, which comprises a true theranostic pair for diagnosing and treating NET patients, leveraging the company’s unique copper-based approach. The Phase 1 program for the diagnostic is the first step in its clinical development and is planned to commence in the first half of 2023. Nuclidium’s TraceNETTM program aims to overcome key limitations of existing radiodiagnostics and their corresponding therapeutics by increasing the sensitivity and diagnostic accuracy of NET imaging, including detecting metastases, while…
RonnyAllan.NET – a review of 2022
ReviewIn 2022, my pet project (my blog) hit 2 million views in early November – that was a major boost. It takes 3-4 years to get a million hits based on current performance. To be honest, I’m still flabbergasted by reaching one million in 2018. It just kinda happened! I am grateful for every single view. 2022 was a challenging year, mainly because the pandemic had some latent impact on my social media activity and also in terms of growth. 2020 and 2021 were slower than normal but 2022 has seen some pickup. Some of it is due to less writing but much…
Incidentally, it’s not NET! SSTR PET e.g. Ga68/Cu64)
Incidental Findings in SSTR PET Somatostatin Receptor (SSTR) PET scans (e.g. Ga68/Cu64) have transformed the imaging landscape for Neuroendocrine Cancer, mainly for well-differentiated NETs, most of which will be somatostatin receptor positive. However, Oncologists/NET Specialists and radiologists must be aware of the various physiologic and other pathologic processes in which cellular expression of SSTR can result in interpretative error. Included in these pitfalls are incidental findings. What is an incidental finding? An incidental finding, also known as an incidentaloma, may be defined as “an incidentally discovered mass or lesion, detected by CT, MRI, or other imaging modality (e.g. PET) performed…
Clinical Trial: Lutathera and ASTX727 in Neuroendocrine Tumours (LANTana)
What is the aim of this clinical trial?The aim of this single location trial in Imperial College London is to determine whether pre-treatment with ASTX727 results in re-expression of SSTR2 in patients with metastatic NETs, using 68Ga-DOTA-TATE to image epigenetic modification of the SSTR2 locus allowing subsequent treatment with Lutathera(i.e. PRRT). Patients entered into the study will receive ASTX727 orally up to 3 to 8 days prior to receiving Lutathera treatment. What is ASTX727?Oral Decitabine and Cedazuridine (ASTX727) is a DNA methyltransferase (DNMT) inhibitor currently being used in a trial to facilitate oral treatment of certain drugs for adults with intermediate…
New Clinical Trial – Testing Lutetium Lu 177 Dotatate in Patients With Somatostatin Receptor Positive Advanced Bronchial Neuroendocrine Tumors
When I see a trial for Gastroenteropancreatic NETs (GEPNETs), I know that BP (Bronchopulmonary) NETs (includes Lung) are not included. When you look at the approval wording for the major treatments in use (PRRT Lutathera, Lanreotide), they appear to use the term GEPNETs making BP NETs the poor relative. Clearly there’s highly complex reasons why NETs react differently in different parts of the body. I can see that BP NET patients were involved in clinical trials for both of the mainstream treatments listed above. The drug approval process is also highly complex, and I can see from the wording that functional…
Dual Tracer (68Ga-DOTATATE and 18F-FDG) PET Imaging in G2 & G3 Gastroenteropancreatic Neuroendocrine Tumours
For some time now, I've been watching the development of PET scans for Neuroendocrine Neoplasms (NENs). I use the term 'Neoplasms' because there are different strategies for well and poorly differentiated types, Neuroendocrine Tumour (NET) and Neuroendocrine Carcinoma (NEC) respectively.It's known that most NETs have somatostatin receptors which makes tumours be seen better on somatostatin receptor-based imaging e.g. 68Ga-DOTATATE or 64Cu DOTATATE, but more aggressive types tend not to have working somatostatin receptors and are better seen on regular PET, i.e. 18F-FDG PET/CT. However, nothing in NENs is simple and there's always outliers. This has been highlighted since the addition…
Generic Somatostatin Analogues for Neuroendocrine Cancer
Generic Somatostatin Analogues. I've covered a lot about somatostatin analogues, particularly the two predominant approved drugs Lanreotide and Octreotide. Recently I found there are some for octreotide and as of Jul 2021, at least one for Lanreotide and is increasing. The reason for publication of this blog is because I was concerned to hear patients asking questions about generic lanreotide and octreotide in my private Facebook group where they were suggesting they could be of lesser quality. I studied that in more detail and here are the results of that research. What are generic drugs? Primer Companies take out exclusive rights…

SSTR PET – Ga68-DOTA-JR11 vs Ga68-DOTATATE
Share on facebook Facebook Share on twitter Twitter Share on pinterest Pinterest Share on whatsapp WhatsApp Share on email Email Headline - 68Ga-DOTA-JR11 was found to detect significantly more liver lesions than 68Ga-DOTATATE; however, 68Ga-DOTATATE detected more bone lesions than 68Ga-DOTA-JR11.Although it had been in trial use for some years in Europe and elsewhere, the formal approval of 68Ga-DOTATATE has led to an increase in the development of other radionuclides, some in conjunction with therapeutic options (i.e. PRRT) making a 'theranostic' approach to diagnosing, treating and surveillance Neuroendocrine Cancer patients with somatostatin receptor positive tumours. I also wrote last year about…
Clinical Trial: Lu-177 DOTATOC (PRRT) in adult subjects with Somatostatin receptor (SSTR) positive Pulmonary, Pheochromocytoma, Paraganglioma, Unknown primary, and Thymic Neuroendocrine Tumors
Excellent news for those who don't have Gastroenteropancreatic NETs (GEP-NETs). A trial of PRRT is being set-up for the less common types of NET including those with an unknown primary. Using the DOTATOC radionuclide rather than the Lutathera model of using DOTATATE, this trial will cater for Pulmonary, Pheochromoctyoma, Paraganlioma, Unknown Primary and Thymic Neuroendocrine Tumours.Excel Diagnostics and Nuclear Oncology Center (EDNOC) announced today that its physician sponsored Investigational New Drug (IND) application to evaluate safety and efficacy of Lu-177 DOTATOC in adult subjects with Somatostatin receptor (SSTR) expressing Pulmonary, Pheochromocytoma, Paraganglioma, Unknown primary, and Thymic Neuroendocrine Tumors (PUT-NET), has…

Peptide agonists of SSTR2 are rapidly internalized…
LUTATHERA (PRRT) – Clinical Trial for Grade 2/Grade 3 Patients Advanced GEP-NET (NETTER-2)
FINAL TRIAL RESULTS PUBLISHED 19TH JAN 2024Read more by clicking here.Original blog below. Brief Summary- The NETTER-1 trials led to the approval of Lu177 (or Lutathera), more commonly known in the community as Peptide Receptor Radio Therapy (PRRT). This led to an explosion of availability across the world but many gaps in service remain.Many PRRT spin off trials are in the pipeline looking at different types of PRRT, mainly using slightly different radionuclides and techniques. However, NETTER-2 builds on the success of the approved version formally known as Lutathera.The aim of NETTER-2 is to determine if Lutathera in combination with long-acting…

Round up of NANETS 2017 – Let’s talk about NETs #NANETS2017
NANETS (North American Neuroendocrine Tumor Society) is one of the biggest NET conferences, bringing together NET Specialists from around the world to discuss state-of-the-art treatment modalities, new therapies, and ongoing controversies in the field of Neuroendocrine Neoplasms (Tumors and Carcinomas). This is fairly complex stuff but much of it will be familiar to many. I’ve filtered out several outputs from the conference which I think are both relevant and topical to patients. The list is below allowing you to easily peruse and read further via linkages if you need to read more. Remember, some of these are extracts so do not…
All you need to know about Peptide Receptor Radionuclide Therapy (PRRT)
Updated 21st August 2025 Short PRRT Primer What is Peptide Receptor Radionuclide Therapy (PRRT)? What is PRRT? PRRT stands for Peptide Receptor Radionuclide Therapy, an FDA-approved therapy used for systemic treatment of neuroendocrine tumors. Peptide refers to the small molecule for this therapy. The Peptide used (e.g. DOTATATE or DOTATOC or DOTANOC) is very similar to Somatostatin, a hormone which binds to receptors found on neuroendocrine tumors. Receptor refers to a specific target on neuroendocrine tumor cells that the peptide attaches to. After the peptide joins with a Receptor, it becomes attached and enters the targeted tumor cell. Radionuclide refers to radioactive atom that is attached to the peptide.…
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…
