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 available if dose adjustment is required for adverse events, drug interactions, and hepatic impairment.
Who can get Everolimus (Afinitor)?
The USA Food and Drug Administration approved everolimus (Afinitor, Novartis) 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.
Europe Medicines Agency (EMA) approved the drug for pancreatic neuroendocrine tumours when the cancer cells are well- or (sic) moderately differentiated* and the cancer is progressing or unresectable. Also approved for neuroendocrine tumours originating in the lungs or gut, when the cancer cells are well-differentiated and the cancer is metastatic or unresectable.
UK‘s drug approval NICE states that Everolimus is recommended as options for treating well- or (sic) moderately differentiated* unresectable or metastatic neuroendocrine tumours (NETs) of pancreatic origin in adults with progressive disease. Also, as an option for treating well-differentiated (grade 1 or grade 2**) non-functional unresectable or metastatic NETs of gastrointestinal or lung origin in adults with progressive disease. the NICE recommendation also states that Everolimus is recommended only when the company provides it with the discount agreed in the patient access scheme.
* moderately differentiated is not a term included in the World Health Organisation classification system for Neuroendocrine Neoplasms – read more about this here.
** since approval, there is now a Grade 3 well-differentiated category, but it is not clear if the drug automatically becomes available for use on Grade 3 NETs.
Other countries as per their own marketing authorisations and approvals.
The efficacy and safety of everolimus was demonstrated in the RADIANT trials:
RADIANT-1. This trial assessed the efficacy and safety of everolimus in patients with metastatic pancreatic NET
RADIANT-2. This trial looked at everolimus in patients with low grade NET plus carcinoid syndrome.
RADIANT-3. Mainly looking at comparing everolimus as a first line treatment in pancreatic NETs vs a later treatment line).
RADIANT-4. The RADIANT 4 trial was the first randomized study to show that everolimus is effective in patients with pulmonary NETs.

Here is my monthly summary of March 2026 on RonnyAllan.NET This has been a very good month but to be honest, I had more time at home and on my computer, due to illness. OK I was not that ill that I could not tap away at a keyboard! However, it was pretty erratic access. I… Read more: March 2026 Newsletter from Ronny Allan - Understanding Differentiation, Ki‑67, Mitotic Count, Hotspots, Pathology Workflow, and Primary–Metastasis Heterogeneity in Neuroendocrine Neoplasms (NENs)
Before you read this… This article discusses pathology concepts such as Ki-67, grading, heterogeneity, and biopsy findings in neuroendocrine tumours (NETs). It is provided for educational purposes only and does not interpret any individual pathology report or scan result. Ki-67 values, tumour grade, and sampling limitations can vary between different biopsies and over time.

Before you read this… This article is provided to support understanding of a complex and evolving topic.

Only your… Read more: Why liver transplant is back in the NET conversation - This too shall pass
If you’ve heard that phrase before, you’re not alone. The phrase is rooted in older Persian and Buddhist teachings, and widely accepted as a testament to the impermanence of all things. Many famous people have used this phrase including Abraham Lincoln, Tom Hanks, Robert De Niro and King Solomon.

Vitamin D is a fat-soluble vitamin (along with A, E and K). Fat-soluble vitamins are absorbed with the other fats from the food you eat. Fat-soluble vitamins can stay in your body for a while. When they’re stored in your body’s fat, they can be stored for up to 6 months until your body needs them. … Read more: Neuroendocrine Tumours (NETs) – Vitamin D (Cholecalciferol / Ergocalciferol) - Cancer: Words are important but so is context
Words are very important to cancer patients, some people hang their hats on them and put their feet up, and some people google them until they are tied in a knot, still fraught with worry.

Vitamin B12 is a water-soluble vitamin. Unlike fat-soluble vitamins, they are not stored in your body long term. They enter your bloodstream, and anything your body doesn’t need is eliminated through your urine. Since water-soluble vitamins don’t last long in your body, they need to be replenished frequently. You can find B vitamins almost everywhere. If you… Read more: Neuroendocrine Tumours (NET) – Vitamin B12 (Cobalamin) - Sometimes you gotta climb that bridge!

When I was diagnosed, I didn’t even feel ill. It was therefore a bit of a shock being told I had metastatic cancer, advanced enough to kill me without treatment. It was hiding But it did make me think back to some minor irritants, or to be accurate what I thought were minor irritants, things that… Read more: Neuroendocrine Tumours (NET) – hiding in plain sight – an awareness post from Ronny Allan - Ronny Allan – just a wee Scottish guy with a computer

USA – Prevalence of Neuroendocrine Neoplasms (NENs) breaches the Orphan Disease threshold for the first time (officially) The latest US SEER figures confirm that staggering increase in the prevalence of NENs.

Neuroendocrine neoplasms (NENs) have outgrown the “rare disease” label. e.g. Across the U.S., UK, and Australia, they now rank among the most commonly diagnosed cancers — yet they remain under-recognised in mainstream healthcare circles, often misdiagnosed in primary and secondary care, but continue to be medically complex requiring specialist input which often arrives late. The… Read more: Reframing Neuroendocrine Neoplasms Beyond “Rare” - Every stripe is lost awareness
Sincer 2015, my message has not changed. My message continues to be justified because since then, many important voices in the NEN community have repeated it! However, there has been, and still remains, some instransigence, although some of that has now buckled in the face of the recent US SEER statistics. However, the buckling needs… Read more: Every stripe is lost awareness
