Clinical Trials – PEN-221 for Neuroendocrine Cancer

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…

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

Clinical Trials, Technical NETs

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…

Genetics and Neuroendocrine Tumors

Awareness, Living with Neuroendocrine Cancer, Survivorship, Technical NETs

In my article 'Ever wonder what caused your NET', I concluded that currently, the only known scientifically explained causes for NETs were hereditary/genetic in nature. This is mostly associated with those who have MEN syndromes (yes, they are a syndrome not a type of tumour) and a few other less common types of NET including Pheochomocytoma/Paraganglioma (Pheo/Para) and Medullary Thyroid Carcinoma (MTC) (the familial version of MTC is often referred to as FMTC). However, please note this does not mean that all those diagnosed with pancreatic, parathyroid, pituarity, Pheo/Para and MTC tumours, will have any hereditary or genetic conditions, many will simply be sporadic tumors. In recent years, it has become increasingly apparent that a number of Neuroendocrine tumours arise as a result of germline genetic mutations and are inherited in…

Ever wonder what caused your NET?

Living with Neuroendocrine Cancer, Survivorship, Technical NETs

OPINION. When you're diagnosed, you go through a whole host of emotions. It's not just the initial shock, the disbelief, the anxiety and morbid worry produced by the words "you have cancer", it's other stuff such as anger and denial. With the latter, the denial normally wears off as you finally accept the predicament. In hindsight, the anger is interesting because there can be a mixture of thoughts including "why me", "what could I have done to head this off"; and would you believe I was even angry that my diagnosis was going to affect my performance at work and even my personal credibility. We all react differently but in general terms our experiences can be categorised into 3 main areas: initial reaction, distress and then adjustment. Initially, I was frustrated…

Immunotherapy: Studies with Neuroendocrine Neoplasms

Clinical Trials, Living with Neuroendocrine Cancer, Patient Advocacy, Technical NETs, Treatment

Headline in April 2019: Update from 2019 AACR Annual Meeting "A combination of two common immunotherapy drugs shrinks rare, aggressive neuroendocrine tumors, according to new research results presented at the American Association for Cancer Research Annual Meeting 2019, held March 29-April 3 in Atlanta". See below under section: - Nivolumab (Opdiva) and Ipilimumab (Yervoy) in Treating Patients With High Grade Neuroendocrine Carcinoma Immunotherapy for Neuroendocrine Neoplasms There's a lot of Immunotherapy stuff out there! However, I also wanted to break it down and perhaps see if I can pick up the what, when, why, where and how in regards to Neuroendocrine Cancer. It's really difficult, not least because the picture is not clear and there is no general roadmap printed, let alone one for Neuroendocrine disease. Immunotherapy for NETs was…

Lutetium Lu 177 dotatate (Lutathera®) – PRRT

Clinical Trials, Technical NETs, Treatment

Short PRRT Primer What is Peptide Receptor Radionuclide Therapy (PRRT)? For those who are still not sure what it's all about. This is a non-surgical treatment which is normally administered intravenously. It's based on the use of somatostatin receptors to attract a 'radiopeptide'. The radiopeptide is a combination of a somatostatin analogue and a radioactive material. As we already know, somatostatin analogues (i.e. Lanreotide/Octreotide) are a NET cell targeting drug, so when combined with radioactivity, it binds with the NET cells and delivers a high dose of targeted radiation to the cancer while preserving healthy tissue in an attempt to reduce or kill tumours. In general, patients tend to receive up to 4 sessions spaced apart by at least 2 months. PRRT will not work on all NETs and not…

Neuroendocrine Tumor Drug Clinical Trial – Cabozantinib (includes news on Pheochromoctyoma and Paraganglioma)

Clinical Trials, Patient Advocacy, Survivorship, Technical NETs, Treatment

What is Cabozantinib? Cabozantinib is an oral drug which works by blocking the growth of new blood vessels that feed a tumour. In addition to blocking the formation of new blood cells in tumours, Cabozantinib also blocks pathways that may be responsible for allowing cancers cells to become resistant to other "anti-angiogenic" drugs. It is a type of drug called a growth blocker. Cabozantinib has been studied or is already in research studies as a possible treatment for various types of cancer, including prostate cancer, ovarian cancer, brain cancer, thyroid cancer, lung cancer, and kidney cancer. During my research, I found that it has a connection to Medullary Thyroid Cancer (MTC) which is a type of Neuroendocrine Cancer, frequently associated with Multiple Endocrine Neoplasia (MEN). Cabozantinib, under the brand name of…

Theranostics for Neuroendocrine Cancer – A Find and Destroy Mission

Awareness, Clinical Trials, Living with Neuroendocrine Cancer, Technical NETs, Treatment

[caption id="attachment_14426" width="1200"] Courtesy of Pashtoon Kasi MD on Twitter https://twitter.com/pashtoonkasi/status/1078675398601396224[/caption] Theranostics is a joining of the words therapeutics and diagnostics. You may also see it conveyed as 'Theragnostics' and these terms are interchangeable. The basic aim of theranotistics is to find and then destroy the 'bad guys'. With Neuroendocrine Cancer, finding the tumours (the bad guys) can often be a challenge - they can be small and/or difficult to find - they are sometimes expert at camouflage. Moreover, once found, they can then be difficult to treat (destroy), as they can often prove resistant to conventional cancer drugs and many are inoperable due to sheer quantity, spread and positioning. When they are found and identified, it's also really helpful to know from the intelligence gathered, how successful the destroy…

Neuroendocrine Cancer – If you can see it, you can detect it!

Living with Neuroendocrine Cancer, Survivorship, Technical NETs

Scanning is a key diagnostic support and surveillance tool for any cancer. Even though you have elevated bloods or urine (....or not), a picture of your insides is really like a thousand words.... and each picture has a story behind it. Scanning can be a game changer in the hunt for tumours and although scans do not normally confirm the cancer type and grade, they certainly help with that piece of detective work and are key in the staging of the cancer. When I read stories of people in a difficult diagnosis, I always find myself saying 'a scan might resolve this' and I always suggest people should try to get one. Even in the case of a story about late diagnosis or a misdiagnosis, I find myself thinking 'if only they had done a…

The 5 E’s (of Carcinoid Syndrome)

Awareness, Diet and Nutrition, Living with Neuroendocrine Cancer, Patient Advocacy, Survivorship, Technical NETs, Treatment

Since my diagnosis, I seem to have been in a perpetual learning phase! What not to do, what not to eat, what not to read! However, early on in my experience, I came across a list of 'E' words (5 of them) which is a handy reminder for Carcinoid Syndrome patients, particularly those whose symptoms are not under control. When I say "carcinoid syndrome" in this article, I only mean the syndrome that is caused by what was once called "Carcinoid Tumors", i.e. mainly serotonin secreting types but include tumours which are well differentiated found in the small intestine, appendiceal, rectal, lung, and one or two other less common places. There are many variations of this list but this is my take! I suspect some of this also applies to…

Running in the Family – Multiple Endocrine Neoplasia (MEN)

Awareness, Living with Neuroendocrine Cancer, Technical NETs

We all know that Neuroendocrine Tumours (NETs) and their syndromes are complex but there is even more complexity to be found in a group of related disorders known as Multiple Endocrine Neoplasia (MEN). I recommend all NET patients should try to understand the basics of MEN and vice versa, particularly as both conditions seem to come with a plethora of endocrine related effects. Overview MEN patients will normally have a tumour in at least two endocrine glands - thus the terms 'Multiple' and 'Endocrine' (tumours can also develop in other organs and tissues). Neoplasia is just another name for tumour and these can be non-cancerous (benign) or cancerous (malignant) with the potential to metastasize. MEN syndromes can comprise varying combinations of tumours and many will be aware of the tumour risks from family knowledge. So putting…

Neuroendocrine Cancer Syndromes – Early Signs of a Late Diagnosis

Awareness, Diet and Nutrition, Living with Neuroendocrine Cancer, Technical NETs, Treatment

One of the curious things about Neuroendocrine Cancer (NETs going forward) is that it can very often exhibit one or more vague symptoms collectively known as a 'syndrome'. Syndrome is an apt word to describe these complications as the most general meaning in medical terms is a group of symptoms that together are characteristic of a specific disorder or disease". Having a syndrome can often be the difference between having a 'functional' condition or a non-functional' condition - see more below. This frequently makes Neuroendocrine Cancer very difficult to diagnose quickly. It's a very devious disease. It's NOT all about Carcinoid Syndrome! Most people think of Carcinoid Syndrome when they discuss NETs. Anyone suggesting that all NET patients get carcinoid syndrome or that all symptoms of NETs are caused by carcinoid syndrome,…

Neuroendocrine Cancer – Horrible Hormones

Awareness, Living with Neuroendocrine Cancer, Technical NETs

Until I was diagnosed with metastatic Neuroendocrine Cancer, I didn't have a clue about hormones - it's one of those things you just take for granted. However, hormones are vital to human health (male and female) and it's only when things go wrong you suddenly appreciate how important they are ........like a lot of other things in life I suppose! The presence of over-secreting hormones (often called peptides throughout) is useful to aid diagnosis albeit it often (but not always) means the tumours have metastasized. It's also a frequent indication that the person has an associated NET syndrome. This is a really complex area and to understand the hormone problems associated with Neuroendocrine Cancer, you need to have a basic knowledge of the endocrine and neuroendocrine systems. I've no intention…
