64Cu-DOTATATE – a potential expansion of the Somatostatin Receptor PET Imaging for Neuroendocrine Cancer?


Edit 10 Jan 2019: RadioMedix and Curium Announce FDA Fast Track Designation For 64Cu-Dotatate.  Read more by clicking here.

Curium and RadioMedix Inc. announce an exclusive agreement to develop and commercialize 64Cu-Dotatate, an investigational positron emission tomography (PET) diagnostic agent for patients with Neuroendocrine Tumors (NETs). RadioMedix is currently engaged in Phase III clinical trials of the agent and expects to file a New Drug Application with the Food and Drug Administration in 2019. This partnership builds on the initial development work conducted by RadioMedix and will benefit from Curium’s regulatory, manufacturing, distribution, and commercial expertise. The radionuclide is not new, it’s been in use for some time, mainly in Denmark.

64Cu is a PET isotope that can be produced at a central location in quantities to meet the commercial needs of hospitals and imaging centers without the supply limitations of nuclear generator-based PET isotopes,” said Ebrahim Delpassand, MD, CEO of RadioMedix. “Once approved, 64Cu-Dotatate will be available to patients in medical centers with PET capability across the country. This will address the shortage or lack of availability of somatostatin analogue PET agents that we are currently experiencing in many parts of the U.S.”

Ga68 PET Shortages explained

This statement is in relation to the current shortage of Ga68 PET radionuclide. For those not aware, the Society of Nuclear Medicine and Molecular Imaging (SNMMI) has written a letter to the FDA about ongoing shortages of generators that produce gallium-68 (Ga-68), a radioisotope used regularly in medical imaging. The letter—available here.

The letter explains that Ga-68 is currently used to produce NETSPOT from Advanced Accelerator Applications (a Novartis company), which was approved in June 2016 to help treat neuroendocrine tumors (NETs) in adult and pediatric patients using PET. NETSPOT, however, is only approved using specific generators. And those generators are only approved for either 400 uses or one year, whichever comes first. This has led to shortages throughout the United States.

SNMMI notes some possible remedies for this shortage. For instance, “a temporary exemption to the 400-elution limit would have a major impact on NETSPOT capacity for patients,” according to the letter. In addition, using a wider variety of generators to produce NETSPOT or using cyclotron-produced gallium chloride are two other methods that could improve production in a relatively short amount of time. “Further discussion with the manufacturers is necessary,” the authors added.

Read more about Ga68 PET and its use in Neuroendocrine Cancer – click here. Worth also noting that RadioMedix is also involved in a number of NET related initiatives including:

1. Trials for a new type of PRRT called ‘Targeted Alpha-emitter Therapy (TAT) – I’ve written about this previously. Read my article here.
2. An exclusive distributor for the TM Isotopen Technologien München AG (ITM) PRRT product currently in trial. I wrote about this here.

How does 64Cu-Dotatate compare with Ga68 PET and Octreotide Scans?

To learn more about previous studies on 64Cu-Dotatate, here’s 2 articles published in the Journal of Nuclear Medicine which are a head to head comparison of 64Cu-Dotatate with Ga68 Dotatoc and with 111 Indium Octreotide (Octreoscan).

Head-to-Head Comparison of 64Cu-DOTATATE and 68Ga-DOTATOC PET/CT: A Prospective Study of 59 Patients with Neuroendocrine Tumors – http://jnm.snmjournals.org/content/58/3/451.full

PET/CT (left) and PET (right) scans of patient with intestinal NET and multiple metastases. More lesions are seen in intestinal region with 64Cu-DOTATATE than with 68Ga-DOTATOC.

Conclusion: 64Cu-DOTATATE has advantages over 68Ga-DOTATOC in the detection of lesions in NET patients. Although patient-based sensitivity was the same for 64Cu-DOTATATE and 68Ga-DOTATOC in this cohort, significantly more lesions were detected by 64Cu-DOTATATE. Furthermore, the shelf life of more than 24 h and the scanning window of at least 3 h make 64Cu-DOTATATE favorable and easy to use in the clinical setting.

64Cu-DOTATATE PET for Neuroendocrine Tumors: A Prospective Head-to-Head Comparison with 111In-DTPA-Octreotide in 112 Patients –http://jnm.snmjournals.org/content/56/6/847.full

Multiple small liver metastases (>10), peritoneal solitary tumor mass, and 3 lymph node metastases shown on 64Cu-DOTATATE PET/CT in patient with pancreatic NET. No foci were detected by 111In-DTPA-OC SPECT (Precedence scanner). All findings on PET were confirmed to be true-positive. (A) 111In-DTPA-OC planar images. (B) 64Cu-DOTATATE maximum-intensity-projection image with arrows pointing at liver and lymph node metastases. Insert is fused PET/CT of peritoneal solitary tumor mass. (C) Axial CT and SPECT of liver. (D) Axial CT and PET of liver revealing several small liver metastases.

Conclusion: With these results, we demonstrate that 64Cu-DOTATATE is far superior to 111In-DTPA-OC in diagnostic performance in NET patients. Therefore, we do not hesitate to recommend implementation of 64Cu-DOTATATE as a replacement for 111In-DTPA-OC.

Summary

The shortage of Ga68 PET radionuclide caused by limitations of the generators in use is unfortunate. Reading the SNMMI letter, I think progress can be made downstream. However, the introduction of a new scanning agent could be useful as long as the trials prove its safety and efficiently and is comparable to current tools. There is no news of any plans to extend this potential new radionuclide outside the US but I suspect that would change following an FDA approval.

If you can see it, you can detect it!

NETwork with Ronny © – Community Newsletter NOVEMBER 2017

Welcome to Ronny Allan’s Community newsletter for November 2017. A very strong beginning of the month due to massive support for my Halloween themed but very serious and hard-hitting post “Neuroendocrine Tumors – no treats, just tricks“. If you’ve not seen it or commented on it, check it out here on the Facebook site (currently 724 shares). I suspect the number of shares will never be beaten (there were 652 within 36 hours) and as far as I know perhaps this is now the most shared NET awareness post ever on social media. The support for this single post was so phenomenal; it actually eclipsed my entire NET Cancer Day effort on 10 Nov! I am so grateful to those who made that happen ♥

That said, I was actually pretty quiet on NET Cancer Day. You have to remember that my contribution is mostly social media, that is my strong point and that is where I focus. It’s a great platform in the ‘awareness battlespace’ for many medical conditions. Moreover, it is where we will find new audiences. More and more doctors of all specialities are joining social media on a daily basis – we need them to find out about NETs.

I was quiet for much of November due to a wee bit of exhaustion, coupled with a slight depression that another year of ‘same old’ messages was taking place. Despite this, I still managed to dominate the social media #LetsTalkAboutNETs campaign.

AND ….. I’m now officially ronnyallan.NET (how apt is that!)

NETwork with Ronny © – Community Newsletter OCTOBER 2017

Hi NETworkers!

Welcome to Ronny Allan’s Community newsletter for October 2017.  A very strong end of the month due to massive support for my Halloween themed but very serious and hard-hitting post “Neuroendocrine Tumors – no treats, just tricks”. If you’ve not seen it or commented on it, check it out here on the Facebook site.  I suspect the number of shares will never be beaten (652 in 36 hours).  31 Oct 2017 is now the biggest number of views on any one day, breaking the previous record set in Jan 2017.  It also made October 2017 the highest monthly views ever.  I am so grateful to those who made that happen ♥

What’s in the NET News

The following news items may be of interest:

  The huge (but expected) news that Novartis Novartis (manufacturers of Octreotide) is purchasing Advanced Accelerator Applications (AAA) (manufacturers of Lutathera Lu-177 (as used in PRRT)). This is a significant acquisition and should benefit the NET community given the size of Novartis and the potential of PRRT worldwide. It will be interesting to see if this has an impact on the UK approval

Theranostics for Neuroendocrine Cancer – A Find and Destroy Mission

 

theranostics

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 (therapeutic) part of the mission might be.

The nuclear scan uses the same nuclear material as the therapy, therefore if you cancer lights up on the nuclear scan, then the therapy will find its way to the cancer and hopefully work well. That is the beauty of theranostic pairing, i.e. the use of the same agent in the diagnostics – the ability to find, estimate likely success criteria and then hopefully destroy – or at least reduce the capability of the tumours and extend life.

A great example of an approved Theranostic Pair in Neuroendocrine Cancer, is the combination of the Somatostatin Receptor based Ga68  PET scan using NETSPOT or SomaKit TOC™ (US/Europe respectively) and Peptide Receptor Radiotherapy (PRRT) using Lutathera which both target NETs expressing the same somatostatin receptor, with PRRT intended to kill tumor cells by emitting a different kind of low-energy, short-range radiation than that of the diagnostic version. As mentioned above, the Ga68 PET scan can give a reasonably indication of therapeutic success using PRRT based on measurements taken during the scan (too complex for this article).

THERANOSTICS – FIND

Octreoscan vs Ga68 PET

Ga68 PET 

Newer imaging agents targeting somatostatin receptors (SSTR) labelled with 68 Ga have been developed, namely, DOTATATE, DOTATOC and DOTANOC. They are collectively referred to as SSTR PET.

The full titles of the 3 types are:

68Ga-DOTA-Phe1-Tyr3-Octreotide (TOC),
68Ga-DOTA-NaI3-Octreotide (NOC),
68Ga-DOTA-Tyr3-Octreotate (TATE).

The main difference among these three tracers (DOTA-TOC, DOTA-NOC, and DOTA-TATE) is their variable affinity to SSTR subtypes. All of them can bind to SSTR2 and SSTR5, while only DOTA-NOC shows good affinity for SSTR3.

These agents have several benefits over In111-pentetreotide (Octreotide scan), including improved detection sensitivity, improved patient convenience due to the 2 hour length of the study (compared to 2 or 3 days with Octreoscan), decreased radiation dose, decreased biliary excretion due to earlier imaging after radiotracer administration, and the ability to quantify uptake. The quantification of the uptake can help decide whether a patient is suitable for PRRT. Eventually, all Octreotide scans should be replaced with SSTR PET.  To confirm the advantages of SSTR PET over Octreotide scans, a study comprising 1,561 patients reported a change in tumour management occurred in over a third of patients after SSTR PET/CT even when performed after an Octreotide scan. Worth pointing out that SSTR PET is replacing the ageing Octreotide scan and not conventional imaging (CI).  You can see the recommended scenarios for use of SSTR PET in this article published by the Journal of Nuclear Medicine

Ga68 PET scans have been in many locations for some time. Current excitement is focused on USA locations with Ga68 PET (NETSPOT) only recently approved (DOTATATE). Other countries/scan centres may use one of the other types of imaging agent.

Read much more about this scan in my detailed article on Ga68 PET here.

So SSTR PETs above have the ability to find and estimate likely success criteria for therapy.  We are now in a position to move on to ‘THERApy’ – e.g.  Peptide Receptor Radiotherapy or PRRT.
