Waiting on Lutetium Lu 177 dotatate (Lutathera®) – PRRT?

Translate this post

Recent Posts


There’s a lot of questions doing the rounds on forums and messages about the approval of Lutathera (PRRT) in USA, Europe and other places.  The latest we know is in the red print headlines below. Followed by an update of known activity by region/country and a short primer for those not sure about PRRT.


ALL7 Dec 2017.  Novartis and Advanced Accelerator Applications (AAA) Announced that Novartis is buying AAA and the process has started.  Read here  This will not have any effect on approval timelines.

EUROPE – 29 Sep 2017.  AAA Announced that the European Commission (EC) has approved the use of Lutetium Lu 177 Dotatate (Lutathera®).  Despite the treatment being used for over 10 years, this is apparently the first ever approval of the therapy.  EU constituent countries are now free to fund and implement services. In the UK, now awaiting action by NICE (see announcement below 3rd and 11th Aug).   Read here

USA – 28 Aug 2017. AAA Announced that the new Prescription Drug User Fee Act (PDUFA) date for Lutetium Lu 177 Dotatate (Lutathera®) would be January 26, 2018.  Read here

UK – 11 Aug 2017.  AAA responds to UK drug appraiser National Institute for Health and Care Excellence (NICE) negative recommendation.  Read here

UK – 3 Aug 2017.  Currently, NICE (the UK equivalent of FDA) are not recommending Lu-177 Lutathera based on cost.  This is only a draft recommendation and another announcement is expected end Sep 2017.  More to follow when known.  This is a blow for patients in England.  Read here

The situation is confusing – the therapy has been in use for some time

Of course, this therapy has been in use in Europe and some other places for some time but to be honest, they have been on a limited scale and never formally approved by national drug agencies.  Despite it’s extensive use, the EU approval above is actually the very first approval of PRRT anywhere in the world.  In UK, it was used for some time for those in need but was removed from routine availability through a ‘slush fund’ formally known as the Cancer Drugs Fund – to cut a long story short, the funding source was cut off. There are still ways of obtaining the treatment pending formal acceptance by the NHS but certain criteria apply.

In the meantime, I constantly see stories of patients travelling to Switzerland, Germany, Netherlands, Sweden and England. I’m sure there’s people travelling to other countries!  However, it does indicate one thing, there is a huge unmet need in that many patients do not have access to the best treatments in their own country. I see this daily through many private messages.

Regional Updates

Europe (EU associated countries)

The European Medicines Agency (EMA) “market authorisation” received a positive indication on 20th July followed by EC approval on 29 Sep 2017.   The positive indication reads “Lutathera is indicated for the treatment of unresectable or metastatic, progressive, well differentiated (G1 and G2), somatostatin receptor positive gastroenteropancreatic neuroendocrine tumours (GEP NETs) in adults”. Of Course, the decision to fund the drug will be with national approval organisations.


Despite the EC approval on 29 Sep 2017, NICE are currently not recommending PRRT (Lu-177) due to what looks to me like cost grounds.  One theory is that this is a metaphor for price negotiation between NHS and AAA.  This is a  particularly controversial issue for UK as the drug was removed from routine use (Cancer Drugs Fund) in 2015.  Why wait in UK?  There are ways to get access to PRRT via different funding sources. Ask your specialist because this possibility is unfortunately not very well publicised.  PRRT is funded in Scotland, Wales and Northern Ireland. NICE only covers England.


The situation in USA looks more favourable, most likely due to the different healthcare system in place …. although whether insurance companies will be quick to sign up, is another question. My guess is it will be approved by the FDA on or before 26 Jan 2018.

Why wait in USA, there’s an extended access program in place (click on the highlighted link to see locations).


PRRT is only available at a few cancer centres in Canada. It can only be used with special approval from Health Canada or by taking part in a clinical trial


Australia seems to be ahead of the game or that is what I sense when I read output from there.  There’s a good section on the Australian effort – click here.

New Zealand

These guys have had to fight to get some progress on the provision of PRRT.  Currently New Zealanders have to go to Melbourne Australia for treatment – almost 50 New Zealanders with NETs are currently raising tens of thousands of dollars to pay for treatment in Australia because the life-prolonging treatment isn’t available locally. But this could change in 2018.  On 21 Nov 2017, Unicorn Foundation New Zealand announced that Pharmac, the New Zealand government agency that decides which pharmaceuticals, have recommended that PRRT be funded for patients with medium priority for the treatment of unresectable or metastatic, well-differentiated NETs (irrespective of primary site) that express somatostatin receptors. This recommendation will be discussed at the PTAC meeting Feb 2018.

Short PRRT Primer

For those who are still not sure what it’s all about.  This is a non-surgical treatment and is based on the use of somatostatin receptors to attract a ‘radiopeptide’. It is normally administered intravenously.  The radiopeptide is a combination of a somatostatin analogue and a radioactive material (radionuclide).  As we already know, somatostatin analogues are a NET cell targeting protein, so when combined with the radionuclide, it binds with the NET cells and delivers a high dose of targeted radiation to the cancer while preserving healthy tissue.  Simple!

PRRT will not work on all NETs and not everyone will suited to this treatment. For this treatment to be successful, you must have somatostatin receptors in your tumors. Success rates are not 100%.

Understanding the terminology is half the battle in understanding the latest radionuclide developments.  I’ve included Ga-68 PET scans as the term ‘Theranostics‘ is becoming a commonly used theme.

LUTATHERA is the radionuclide ‘mix’ for use in Peptide Radio Therapy Treatment (PRRT). It is still waiting for approval in USA. The delay is due to an issue with the data which has now been resubmitted.  You may also see this drug called ‘Lutetium’ or ‘Lu-177 dotatate’, or just ‘Lu-177’ on its own. Yttrium 90 (Y-90) is a  radionuclide also used in PRRT. 

NETSPOT is not PRRT but is the radionuclide mix for use in Gallium 68 (Ga-68) PET diagnostic scans and was recently approved in USA.  SOMAKIT TOC is essentially the European equivalent of NETSPOT and is approved in Europe.

Together they form a ‘theranostic pair’. Theranostics is a joining of the words diagnostics and therapy. Theranostics is apt as together (NETSPOT / SOMAKIT TOC and Lutathera), both target NETs expressing the same somatostatin receptor, with Lutathera intended to kill tumor cells by emitting a different kind of low-energy, short-range radiation than that of the diagnostic version.

Moreover, thanks to the theranostic approach that nuclear medicine allows, AAA’s NETSPOT/SomaKit TOC products will be able to determine when Lutathera is the appropriate treatment.

What’s next for NETs PRRT?

  1. two radiopeptides together;
  2. radiopeptides in conjunction with other chemotherapies (check out my article PRCRT);
  3. repeated administrations of the radiotherapies;
  4. other radionuclide-peptide combinations (….article to follow);
  5. increasing the number of indications for this therapy, including other disease targets;
    • e.g. they are already using it for Prostate Cancer.
    • e.g. new radionuclides – see my article about the COMPETE trial.

    I was diagnosed with Neuroendicrine cancer in May 2015. I was then treated with Sandostatin LAR every 4 weeks but the cancer kept on spreading. I had my second Lutathera treatment last week. The PET-scan, however, showed that the tumors “looks slightly more intense but with no significant increase in size.” Is this normal? What is the maximum number of treatments that can be done safely? My white cell- and blood platelet count is very low.

      As I understand it, the max Lutathera (PRRT) is 4. However, i know people in Europe who have done more including a lady on 11! Personalised dosing is being looked at and is already in place in certain European centres. I have no idea what they mean by ‘intense’, perhaps ‘hypervascular’. As for white cell and platelets, unsure of this, better to ask your doctors. Good luck for your treatment.


  2. My Oncologist counsels to forget PRRT as long as Octreotide works. i feel fine and liver tumors are even shrinking. My only concern is that if Octreotide and PRRT target the same receptors then when/if Octreotide stops working, PRRT potential success will also decline.

      In UK you won’t get it unless you other treatment isn’t working or tumors are progressing. Some people are suggesting it could be a first line treatment. I suspect private providers might hope so he said cynically 😃 I’m with you, I hope it’s there when I actually need it


  3. Desi says:

    Thank you, Ronny, as always.
    I travel to Singapore for PRRT and the PET dotascan. I’m grateful it is only around 3 hours away by airplane from my country. For now, only one hospital there does PRRT, but by the latter part of the year, another hospital will have it as well.
    I’ve had 1 session so far. Do any of you know if it’s too early to tell through a PET dota or some other scan if PRRT is actually working for me? I have PNET Glucagonoma with liver mets. Thanks.

    I had my 8th Lutetium (Lutathera) treatment last week. It has been available in Canada since 2010, though only used in two locations that I know of. I am fortunate to live a 2 hour drive from one of them. I’m waiting for the results of the latest post-treatment scan, but up to this point, there there has been no spread of disease since diagnosis and my existing tumours have been shrinking. I feel 100% well and I’m able to lead a pretty normal life. It frustrates me that this treatment isn’t readily available to NETS patients everywhere.

      Lutathera – is a brand name of Lu177 Dotatate – NETSPOT and Somakit are brand names as well. NETSPOT and SOMAKIT are different drugs (one is Dotatate and one is dotatoc) Other companies make other version of PRRT drugs (Lutate for instance)


      • Ed V Ost says:

        NETSPOT and SOMAKIT are diagnostic equivalents to Lutathera – isotope is switched from Gallium-68 for PET scan in NETSPOT and SOMAKIT to Lu-177 (Lutathera) for therapy


    • Simon Pedro Arroyo says:

      Hello hi i would love to hear your results with this treatment i live in usa and it is really frustrating that this is not available here, if it works i might as well travel to Canada to get this treatment i have the same disease now im doing fine with the sandostatin every four weeks but is just to control the symptoms so if you don’t mind please let us know if this worked for you, thank you and good luck…

        I’ll have my next CT scan on August 30 and as long as that goes well, another treatment around the beginning of November. By all means, check my blog for updates around those dates. If there’s any other information I can help you with, please let me know!
