Curtis Crump: Credit MD Anderson Cancer Center Curtis Crump has an amazing story to tell.  Given 6 months to live, he refused to accept that prognosis and looked elsewhere. He found a top hospital that directed him to an established clinical trial.  Although the story I am attaching says "Neuroendocrine Tumors" throughout, with that prognosis and the treatment he received (chemotherapy and immunotherapy), I'm reasonably confident he had a Neuroendocrine Carcinoma (Colon primary) or a Grade 3 Well Differentiated NET.  Nonetheless, his story is relevant to many people's experiences across the broad spectrum of Neuroendocrine Neoplasms (NENs). And if I am right in my assumption, even with a poorly differentiated type, there is the hope of a better prognosis. Wishing Curtis the very best.  Read his story below.(Please see my disclaimers…

Survival Outcomes in Metastatic Gastroenteropancreatic Neuroendocrine Tumor Patients receiving Concomitant 225Ac-DOTATATE Targeted Alpha Therapy and Capecitabine: A Real-world Scenario Management Based Long-term Outcome Study

Survival Outcomes in Metastatic Gastroenteropancreatic Neuroendocrine Tumor Patients receiving Concomitant 225Ac-DOTATATE Targeted Alpha Therapy and Capecitabine: A Real-world Scenario Management Based Long-term Outcome Study

Clinical Trials
Introduction I've written about both 225Ac-DOTATATE targeted alpha therapy (TAT) and Capecitabine before but never as a concomitant pair (combo). So, when this Indian study came up on my radar, I felt it was a useful addition to my website adding to my existing targeted alpha therapy portfolio of information.  India appears to be using more of this type of PRRT than any other country.

Assessment of Clinical Response Following Atezolizumab and Bevacizumab Treatment in Patients With Neuroendocrine Tumors: A Nonrandomized Clinical Trial

Assessment of Clinical Response Following Atezolizumab and Bevacizumab Treatment in Patients With Neuroendocrine Tumors: A Nonrandomized Clinical Trial

Clinical Trials
Background Well differentiated NETs have been described as an "immunological desert" in recent years mainly due to the poor response rate data coming out of clinical trials of immunotherapy drugs.  Poorly differentiated NEC has favoured better but mainly in the more obscure types.  Which is why these data of a combo treatment containing one immunotherapy drug caught my eye. What is atezolizumab?   It's a Programmed cell death protein -1 (PD-1)/ Ligand 1 (PD-L1) inhibitor i.e. it's a classic immunotherapy treatment.  A drug that binds to the protein PD-L1 to help immune cells kill cancer cells better and is used to treat many different types of cancer, including cancers that express PD-L1. Atezolizumab is used alone or with other drugs to treat certain types of melanoma, hepatocellular carcinoma (a type of…

Clinical Trial: Triapine and Lutetium Lu 177 Dotatate for Neuroendocrine Tumors

Clinical Trials
What is PRRT? I'm guessing most of my readers know what Peptide Receptor Radiotherapy (PRRT) is.  But for those new to this field, read more here What is Triapine? Triapine is a ribonucleotide reductase (RNR) inhibitor, I.e. it helps repair DNA.  When I research this drug, I can see it is used in numerous examples of clinical trials in an anti-cancer setting alongside radiotherapy and chemotherapy, in many cancers. Triapine in NET There is currently a trial of Triapine with Lutathera (PRRT) (11 major US hospitals).  This study was testing the hypothesis that triapine is an effective radiation sensitizer that can be safely combined with peptide receptor radionuclide therapy and can improve antitumor activity of Lutetium Lu 177 Dotatate, e.g. increase the objective response rate (ORR) above that found in…

Histotripsy: A new technique which destroys cancer using soundwaves (now in Clinical Trials)

Clinical Trials, Treatment
Illustration of histotripsy technology. Image courtesy of Medicine at Michigan Magazine. A new technique that destroys cancer using soundwaves.  It also spurs the immune system to kill off any of the tumour left, scientists have revealed. The non-invasive treatment only needs to be partially effective to stop the cancer spreading.It is currently being tested on human liver cancers in the US and Europe following successful trials in rats. The team from the University of Michigan showed the non-invasive sound technology is able to prevent further spread with no evidence of recurrence or metastases in the majority of cases. The treatment, called histotripsy, noninvasively focuses ultrasound waves to mechanically destroy target tissue with millimetre precision. In many cases, the entirety of a cancerous tumour cannot be targeted directly in treatments due to…

Breaking News It doesn't seem that long since we got the new improved injection delivery system for the current model of Lanreotide.  I had to look at my blog articles for the announcement of that and was surprised it had already been 3 years.  It may be a shorter time period for many though, UK was near the front of that rollout.  I personally found the new injection a better experience and I know the nurses were happier too.  However, I also know there was some disappointment that the injection gauge and length were the same and therefore there was little change for many in terms of the 'experience'.  Speaking from a personal perspective, there was not sufficient change for me to consider moving to self-inject. I know (at least…

Clinical Trials, Treatment
An interesting trial centred on SW USA.   The use of CAPTEM following surgery in high-risk pancreatic NETs (G2/G3 well-differentiated).  Also includes the use of NETest at 3 time points, which is very interesting considering the recent withdrawal of Chromogranin A from US NET Guidelines.  (Read about NETest here). Randomized Phase II Trial of Postoperative Adjuvant Capecitabine and Temozolomide versus Observation in High-Risk Pancreatic Neuroendocrine Tumors (S2104) is a recently activated National Clinical Trials Network randomized phase II trial designed to compare CAPTEM chemotherapy versus observation following resection of pNETs (see Figure 2).

This is all the information available and further details to follow if any is published.  Remember, this is not yet an approved treatment, nor is it widely available.  Only ever used in experimental/compassionate situations.

A Trial to Assess Efficacy and Safety of Octreotide Subcutaneous Depot (CAM2029) in Patients With GEP-NET (SORENTO)

A Trial to Assess Efficacy and Safety of Octreotide Subcutaneous Depot (CAM2029) in Patients With GEP-NET (SORENTO)

Clinical Trials, Treatment
Some of the key differences between Lanreotide and Octreotide long-acting are:1.  Octreotide long-acting needs constituting prior to administration - Lanreotide comes prefilled. 2. Octreotide long-acting is administered intra-muscular, Lanreotide is deep subcutaneous. 3.  I probably should add Octreotide LAR cannot be self-injected but Lanreotide can.  I suspect this type of delivery system may open up that possibility for Octreotide LAR. So, this clinical trial caught my eye.  A version of octreotide long-acting which is prefilled and given subcutaneously.  Plus, the manufacturers say it has a much higher bioavailability than the standard product Sandostatin LAR (bioavailability is the proportion of a drug or other substance which enters the circulation when introduced into the body and so is able to have an active effect).CAM2029 might therefore be considered a generic of Sandostatin LAR but better…

CAR-T clinical trials for Neuroendocrine Cancer

CAR-T clinical trials for Neuroendocrine Cancer

Clinical Trials, Treatment
What is CAR-T?CAR-T – chimeric antigen receptor T-cell – therapy is specifically developed for each individual patient and involves reprogramming the patient’s own immune system cells which are then used to target their cancer., i.e. it's an immunotherapy. It is a highly complex and potentially risky treatment, but it has been shown in trials to cure some patients, even those with quite advanced cancers and where other available treatments have failed.The treatment involves several steps over a number of weeks. First the patient’s blood is taken and is sent off to the manufacturer’s laboratory. Here the patient’s blood is ‘trained’ to fight the cancer cells. The CAR-T blood is then transported back to the hospital and the patient is administered with the CAR-T to treat their condition.It has not been deployed in…

I like reading the words of Dr Mark Lewis, an Oncologist and a Neuroendocrine Tumour (NET) patient himself (with MEN1).  He always delivers with "enthusiastic vigour", a term he reduces to "brio" (which I had to google!)His article as usual sets a scene and he has form for looking back in the history of NETs. I'm sure he does this as it can often illustrate just how much clinical progress has been made since way back then. And that is the purpose of the recent article entitled "Continuing the Odyssey in the Land of Small Tumors".  He quotes from a 1987 article written by Dr Charles Moertel entitled "An Odyssey in the Land of Small Tumors" and I suspect he selected this article from Dr Moertel as he too writes…

Lutetium 177Lu-Edotreotide Versus Best Standard of Care in Well-differentiated Aggressive Grade-2 and Grade-3 GastroEnteroPancreatic NeuroEndocrine Tumors (GEP-NETs) – (COMPOSE)

Clinical Trials
ITM Isotope Technologies Munich SE (ITM), today announced that the first patient has been treated in its second pivotal phase III clinical trial, COMPOSE (NCT04919226), evaluating the company’s lead radiopharmaceutical candidate, ITM-11 (n.c.a. 177Lu-edotreotide), for the treatment of gastroenteropancreatic neuroendocrine tumors (GEP-NETs). ITM-11 is a Targeted Radionuclide Therapeutic consisting of the high-quality radioisotope no-carrier-added lutetium-177 (n.c.a. 177Lu) fused with a somatostatin analogue to specifically target somatostatin receptor-positive (SSTR+) GEP-NETs. While COMPOSE is evaluating ITM-11 for the treatment of well-differentiated high grade 2 and grade 3 GEP-NETs, the radiopharmaceutical is also being investigated in ITM’s ongoing pivotal phase III trial, COMPETE (NCT03049189), in patients with grade 1 and 2 GEP-NETs. GEP-NETs can occur in the pancreas or in other parts of the gastrointestinal tract. Due to their frequent asymptomatic and progressive nature, GEP‑NETs…

Clinical Trials
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 BP NETs with carcinoid syndrome can qualify at least for somatostatin analogues (Lanreotide and Octreotide).  That is not to say BP NET patients cannot get access to these treatments, I…

Clinical Trials
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 of a Grade 3 Well Differentiated NET into the equation.The variable clinical outcome of patients with G2 & G3 well diff Gastroenteropancreatic Neuroendocrine Tumours (GEP NETs) makes the selection of…

Headline:  Roughly 40% of patients with advanced, progressive gastroenteropancreatic neuroendocrine tumors (GEP-NETs) treated with pembrolizumab (Keytruda) in combination with lanreotide (Somulatine Depot) achieved stable disease, according to results from the phase 1b/2 PLANET clinical trial presented during the 2021 American Society of Clinical Oncology (ASCO) Gastrointestinal Cancer Symposium.I've written about Pembrolizumab (Keytruda) before in my general immunotherapy coverage - click here.  I did note they weren't really having much luck with Neuroendocrine Neoplasms although I do see some success (.... but not enough) in poorly differentiated carcinomas.  Well differentiated NETs remain an immunological desert.  However, this poster abstract from ASCO GI conference caught my eye.“Pembrolizumab has antitumor activity in a subset of GEP-NETs patients,” wrote the investigators. “We hypothesized that the lanreotide, by its antitumor effects and reduction of serotonin,…

It's estimated that around 5-10% of Neuroendocrine Neoplasms (NENs) have an unknown primary - what that means is cancer cells have been found in the body but the place cancer began remains unknown.  I wrote about this issue in more depth in my article "Needle in a haystack" - you can read that here.  In that article, you will note that NET specialists through their knowledge and understanding of the behaviour of these comped tumours, can often drill down and gather various pieces of evidence to help narrow down the primary location. However, this new study would indicate they could have access to a new tool to be able to home in on a particular location.DNA methylation-based profiling is now routinely used in the diagnostic workup of brain tumors but…

It covers how to select patients for PRRT in the first place, i.e. who is most likely to get a good response to this treatment and then look at how to track and assess that response. The important thing I gathered from reading is that none of this is a precise science, there are too many variables.  And while this article focusses on the clinical factors, there can of course be non-clinical factors in play in different countries…

The NETest® – a Chromogranin A replacement and more?

Clinical Trials, Patient Advocacy
Tumour Markers GeneralFor some years the gold standard tumour marker for Neuroendocrine Neoplasms (NENs) has been and remains today, Chromogranin A (and for certain scenarios Chromogranin B and C can provide some additional clues).  Pancreastatin, which is actually a molecule of Chromogranin A, is another marker touted but appears to be limited to USA. Its main advantage is the ability to better handle the effects of Proton Pump Inhibitor (PPI) use which is prevalent in the general population.  As we move to a new era of molecular/genetic tumour markers, there's a danger that NENs will be left behind, stuck with diagnostic tools not capable of meeting new demands. I see a lot of public criticism of Chromogranin A, but it's mainly directed at the problem of being skewed by the use…

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 another option called 64Cu, something already available in Europe, in particular Denmark.In another development which has been running for some time, a Ga68 variant called 68Ga-DOTA-JR11 has been in trial…

Targeted Therapy for Neuroendocrine Cancer – Sunitinib (Sutent)

Targeted Therapy for Neuroendocrine Cancer – Sunitinib (Sutent)

Clinical Trials, Treatment
Click here to see the A to Z of Neuroendocrine Cancer What is Sunitinib (Sutent)? Manufactured by Pfizer, this is a targeted biological therapy or more accurately, a multitargeted tyrosine kinase inhibitor (TKI).  You may also see it described as an anti-angiogenic agent on the basis that these tumor types are highly vascularized and show high expression of something called vascular endothelial growth factor (VEGF), a key driver of angiogenesis in neuroendocrine tumors. Because NETs are generally hypervascularized tumors, treatment with antiangiogenic drugs seems a rational approach. A complex process but in the simplest of terms, sunitinib blocks a particular enzyme and keeps tumors from making their own blood vessels, which are needed to deliver oxygen and other nutrients to help them survive and grow. In clinical trials, SUTENT was…

Targeted Therapy for Neuroendocrine Cancer – Everolimus (Afinitor)

Clinical Trials, Treatment
Click picture to read the A to Z of Neuroendocrine Cancer What is Everolimus (Afinitor)? Manufactured by Novartis, this is a targeted biological therapy or more accurately, a mammalian Target of Rapamycin (mTOR) inhibitor. It works by stopping some of the signals within cells that make them grow and divide. Everolimus stops a particular protein called mTOR from working properly. mTOR controls other proteins that trigger cancer cells to grow. So everolimus helps to stop the cancer growing or may slow it down.  The drug is also approved for Renal Cell Carcinoma (RCC) and hormone-receptor-positive advanced Breast Cancer.The drug is administered in oral form (tablet). The recommended dose for AFINITOR® (everolimus) Tablets is one 10-mg tablet once daily but lower doses of 7.5-mg tablets, 5-mg tablets, and 2.5-mg tablets are…

NETDetect: Earlier diagnosis of Neuroendocrine Cancer gets a boost

Clinical Trials
[caption id="attachment_16474" width="640" align="aligncenter"] Dr Eugene Woltering - NET Specialist[/caption] It's well known that Neuroendocrine Cancer is difficult to detect and as a consequence, many people are not diagnosed until late stages. The difficulty in detection is not just focussed on the complexity of the disease but also the lack of understanding within the medical community who don't always see sufficient evidence to refer the person on to receive expensive testing and in some cases confirmatory and expensive imaging which may not show small tumours. Currently, there's no screening test for Neuroendocrine Cancer for the simple fact that it's not a high population disease and it's not a known killer. This development from well known NET Specialist Dr Eugene Woltering could help bridge that gap although some suspicion to utilise…

Clinical Trials – PEN-221 for Neuroendocrine Cancer

Clinical Trials
What is PEN-221?Tarveda Therapeutics is discovering and developing a new class of potent and selective precision oncology medicines for the treatment of patients with various solid tumor malignancies. Their strategy includes developing their own proprietary Pentarin miniature conjugates to enhance the effectiveness of promising anti-cancer payloads that have struggled without their selective targeting to solid tumors.  These medicines are known as 'Pentarins'. PEN-221 is the lead candidate 'Pentarin' aimed at Neuroendocrine Cancer - PEN-221.Somatostatin receptor 2 (SSTR2) is frequently overexpressed on several types of solid tumors, including neuroendocrine tumors and small-cell lung cancer. Peptide agonists of SSTR2 are rapidly internalized upon binding to the receptor and linking a toxic payload to an SSTR2 agonist is a potential method to kill SSTR2-expressing tumor cells. PEN-221 is a conjugate consisting of microtubule-targeting…

Clinical Trials – ONC201 for Neuroendocrine Cancer (including Pheo/Para)

Clinical Trials
What is ONC201?A company called Oncoceutics is developing a novel class of safe and effective cancer therapies called imipridones. Imipridones have a unique three-ring core structure and selectively target G protein-coupled receptors (GPCRs), the largest class of membrane receptors and a common target of approved drugs that are underexploited in oncology. Despite being historically uncommon as targets in oncology, GPCRs control an array of critical prosurvival and stress signaling pathways that are often dysregulated in human cancer to favor cancer cell survival and propagation.The ability of imipridones to target GPCRs with a high degree of selectivity represents a novel opportunity in oncology that generates remarkably safe and effective therapeutics. ONC201, the founding member of this novel class of therapies, is an orally active, safe, and selective antagonist of the GPCR…

LUTATHERA (PRRT) – NETTER 2 Clinical Trial for Grade 2/Grade 3 Patients Advanced GEP-NET (NETTER-2)

LUTATHERA (PRRT) – NETTER 2 Clinical Trial for Grade 2/Grade 3 Patients Advanced GEP-NET (NETTER-2)

Clinical Trials
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 octreotide prolongs PFS in GEP-NET patients with high proliferation rate tumors (G2 and G3), when given as a first line treatment compared to treatment with high dose (60 mg) long-acting octreotide. Somatostatin analog (SSA) naive patients are eligible, as well…

Clinical Trial: Treatment of IBS with diarrhoea – titrated ondansetron (TRITON)

Clinical Trials
I was never diagnosed with Irritable Bowel Syndrome (IBS) but sometimes I feel like I now have it.  I know many others feel the same way.  But when I look at the alternatives, I can't help thinking it's a small price to pay given that one of them might be a slow degrading quality of life until shuffling off  this mortal coil. If I had the choice again, I would still take the surgery. Before the article continues, let me be clear - I'm not suggesting this is a potential treatment for NET patients with post abdominal surgery side effects or side effects of any other treatment, nor am I suggesting it's a potential treatment for those with carcinoid syndrome diarrhea.  I publish it because there is a connection to…

Share on facebook Facebook Share on twitter Twitter Share on pinterest Pinterest Share on whatsapp WhatsApp Share on email Email The treatment of liver metastasis is a common approach following a metastatic diagnosis or discovery of liver metastasis downstream via re-staging. In addition to surgery, there are several liver directed therapies available via embolization techniques. This comes in several flavours:1. Bland liver embolization - a minimally invasive technique which simply blocks the blood supply to the liver tumours in an attempt to reduce or kill those tumours. Sometimes called Hepatic Arterial Embolization or HAE.2. Chemotherapy liver embolization - as above but adds in some cytotoxic chemo to the mix. Sometimes called Trans Arterial Chemo Embolization or TACE.3. Radioembolization is a minimally invasive procedure that combines embolization and radiation therapy to…

Clinical Trial SPARTALIZUMAB – Immunotherapy for Neuroendocrine Neoplasms (PDR001)

Clinical Trials, Treatment
PDR001 (anti-PD-1) is an investigational immunotherapy being developed by Novartis to treat both solid tumors and lymphomas (cancers of the blood).  It is currently being trialled on many cancers including Neuroendocrine.  It's brand name is SPARTLIZUMAB. How PDR001 works PDR001 is a type of immunotherapy, meaning that it acts by activating the body’s own immune system to recognize and fight cancer cells. Normally, an immune system cell called T-cells recognizes and kills infected or abnormal cells, including those that are cancerous. To prevent T-cells from accidentally damaging healthy and essential tissues, however several immune system checkpoints exist to inhibit, or block, them from going about this work. One example is the programmed cell death 1 (PD-1) pathway. Healthy cells produce and display a protein called programmed cell death ligand-1 or…
