New randomized clinical trial of Lu-177-PSMA-617 for men who are still hormone sensitive

Novartis announced a new international Phase 3 clinical trial slated to begin 3/5/21 for men with metastatic hormone-sensitive PC. There will be a crossover after SOC failure, so everyone will get the drug. They haven't announced the sites yet, but with a sample size of 1126, I expect it will be the same as the VISION trial.

They had previously announced a new trial for men who are castration-resistant and have failed one second-line hormonal agent, but have not yet used chemo:

Thanks TA for posting this. I am on a clinical trial at MSK and taking ADT(Firmagon) and HS, do you think I can apply for this one? Will MSK agree? Thank you.

One more question please, do you think I need it? Thanks again.

They only allow 45 days of prior ADT is allowed, so you've exceeded their limit.

Wow, I just questioned recently why there are so few trials with hormone sensitive guys. Couple of quick questions: Did I read correctly that if you are currently on Lupron you don't qualify? So for me I'd have to stop for 12 months to qualify. Is it the same for Zytiga/AA?

Tall_Allen profile image
Tall_Allen in reply to GoBucks

They want relatively newly diagnosed, so they only allow 45 days of ADT. They allow up to 45 days of Zytiga too. Because they require evidence of PSMA avidity, they don't want it hidden by long-term ADT use.

GoBucks in reply to Tall_Allen

Of course, makes sense. My PSA is currently <0.01 so a scan would show nothing. But if LU-177 works it is great to see this trial done earlier. So many seem to wait too long.

Thanks for the post! I think this may be what I’m looking for as the best option so far for a non-SOC alternative.

Thanks TA.

In December 2019, I was diagnosed with mPC. Initial PSA was 46 and Gleason 8/9. Positive in the lymph nodes but no mets in bones. I have been on ADT for 13 months and Xtandi for 9 months. I had radiation treatments last Spring. Currently, my PSA is < 0.1.

Please explain the statement, "There will be a crossover after SOC failure, so everyone will get the drug".

Given my current good state, is this something I should consider at this point in time or hold off for a later date?

Tall_Allen profile image
Tall_Allen in reply to rm9x

They do allow adjuvant ADT for up to 2 years; however,they allow LN metastases if they are non-pelvic (stage M1a) and at least 1.5 cm and they are present 28 days before you start the trial, so I doubt you'd qualify.

The crossover means that those patients who are randomized to get standard-of-care will get the Lu-177-PSMA-617 treatment anyway after they show signs of progression.

I am showing my lack of knowledge but have to ask - is this a major game changer for men with APC ? Using the over- used analogy of horse out of the barn , would this stop every horse that left? 🤷🏻‍♀️

Whether or not it's a game changer is just what the trial will determine. I hope so.

I've grown to hate that phrase. Every time I see it used, it seems to be about a development that adds, at months to survival rather than a longer indefinite period.

Tall_Allen in reply to dhccpa

In the mHSPC setting, we now have 4 drugs that add a lot longer than a few months to survival.

hi Tall_Allen, I have just before Xmas been diagnosed, and i am about to undergo Eligard, SC inj. 22.5....3 monthly inj. plus RT, EBRT therapy after six months of eligard, in my case Gleason (4+3) 7, slight seminal ves, involvement, iliac node, and pelvic side wall node, 25 samples, with 24 pos, Psa 138, DtRe-3 pi-rads 5, psma pet-ct, but no iodine contrast for ct, just the radio dye for pet, mri showed prostate 55cmm, some neural involvement, treatment palliative eligard 22.5, 3 month, locally advanced prostate, i have read up on side affects and am a little worried as i have just been diagnosed with type 2 diabetes at the same time as prostate cancer, and just started taking metformin modified release, 500.

I am 72 years old and worked all my life as an electrician and security installer, now i have retired, my mum and dad died at age 58 with myocardial infarction, and my sister had her first minor heart attack at age 62, but no prostate cancer, in my Family history that i am aware of, is there any side effects that you, or any of your colleagues may have experienced, using Eligard, or lupron, in their follow up treatments, and have you heard of alternate therapies such as...Aloe-Emodin, ....ganoderma-(reishi mushroom), Essiac, coupled with Cbd oil, and thank you again for any help you may offer, as i am a new member to this site, and best regards for now.

Tall_Allen profile image
Tall_Allen in reply to millythefox

Yes, I have heard of those alternate therapies. They do not work. You will die more quickly if you use them instead of Eligard. If you want to take those in addition to the therapies that are known to be beneficial, it may improve your peace of mind.

The only way to slow down death is to add other therapies to Eligard, either docetaxel or one of the second-line hormone therapies (Zytiga, Xtandi, or Erleada) that have been proven to increase survival in men with your diagnosis.

TA- you are the bomb 💣 for your research and support. 🙏. May you be safe, happy, healthy and live with ease

Although my MO disagreed with my assessment, that mHSPC patients seemingly must wait until the disease progresses, and sometime that the second line hormonal therapy fail, in order to qualify for some of these trials, it's appears as that's exactly what they do. It's unfortunate for those of us currently fighting...

I'm newly diagnosed as mHSPC... And my question during my last consult with him discussed this very point. How chosing a path, potentially excludes you from other later. Big difference with low grade, low burden disease patients is the luxury of time!

These trials, should include a separate arm, tracking patients outside the protocol, if anything to see if there are hypothesis being overlooked! The standard of these drugs being used in late stage care, then slowly brought in to earlier phases of progression is a slow and exhausting paradigm! We are reacting to studies started a decade ago and those patients numbers and tracking being formulated today. And yes, they are allowing for great inroads for patients to use drugs unavailable to their staging just a year or two ago.

Arrrrgh... I know I'm spitting in the wind here, just rambling now, apologies ;)

Thanks for posting, is interesting and certainly good to keep an eye on.

Best Regards

They always start with the sickest patients first because (1) it is most ethical and (2) it takes less time to get results and approval. Novartis is starting these trials even before FDA approval. That is a risk for them, but hints at good results to come from the VISION trial. The good news is that the FDA is now allowing median radiographic progression-free survival as the primary endpoint, considerably speeding up the process.

TA, seems like 45 days of ADT is very narrow, almost like you would have to be in that short window of time where you were diagnosed with metastatic disease and considering ADT as a next step but have either not started it or just started. Most guys are just trying to manage SOC and next steps, let alone considering a clinical trial at this point. Do the folks who are running these trials just hand pick who they want and reach out to them via their MOs? I'm curious how this works. My husband has had 65 days so wouldn't qualify even it was available an something to consider.

Tall_Allen profile image
Tall_Allen in reply to mrssnappy

They are really trying to get newly diagnosed patients. They are trying to prove that Lu-177-PSMA-617 is as good as a first therapy as chemo, Zytiga, Xtandi or Erleada. Once they can prove that, it would take its place as a new standard of care.

mrssnappy profile image
mrssnappy

I get it TA, just think it's a very narrow timeframe window for guys to get into this trial.

Just finished my third and final cycle of Lu-177. All mets are gone( with one exception) and PSA 0.62 just before third infusion. I did have one met on scapula which was the largest and it is barely seen on PSMA scan. Dr. Sen feels strongly that it will not require external beam radiation. The third infusion dosage was reduced. Until other therapeutic modalities surface this looks like a game changer when coupled up with PSMA scanning which is now becoming available. The three metrics that is considered. 1. Clinical picture...Pain...In my case it was gone 30 hours after first infusion with multiple mets, spine, humerus ,scapula, pelvis and one node). 2. Blood chemistry to include PSA ( my PSA started to drop and never bounced ). 3. Scans continued to show tumor reduction.

I feel that if we can get the PSMA scans early it will give everyone a more clear choice as to their treatment plan. Charlie and I chose this path because our options were shrinking and Patrick Turner had a big impression on my OC whom was involved in the VISION trial. This was a doable choice but it takes some determination. It will become easier once a Covid vaccine is here for travel but still doable today. Now that PSMA scanning is here I would encourage one to stay on top of it and if you are early in treatment ,consider checking on the trail that Tagawa has underway. I would have loved to been included but did not qualify because finally my mets showed up on standard scans....Blue Skies and Tailwind always

I posted this here since Lu-177 is getting to be a hot topic .

I agree with you Pilot about the PSMA PET scan helping us if done as SOC like it is over there. When I had my first PSMA PET scan over there in March, 2017 it made me really fell I was doing the right thing in regards to treatment. Just wish they were the same price here or even half the price. I paid between $300-550USD for the five I had in Delhi. If and when my PSA goes up, and I am inclined to say when it goes up the very first thing I plan on doing is flying to see Dr. Sen to see if I am PSMA avid and hist it hard immediately to hopefully give me some more quality time. Never thought I’d be here 6 1/2 years after dx’d with a PSA of 212 and Gleason 9. I also want to try stem cell treatment that they have there for diabetes. After I had the tumors melt I had it in Ahmedabad, India for my knees. It actually made a big difference in my knees.

Great news to hear that they are starting this now as it will likely lead to approval (hopefully) for earlier HS disease where it can likely be even more effective. Wish they had done that with Provenge way back when.

TA, are they combining Lu177 with ADT in this trial? And also ARDT?

Tall_Allen profile image
Tall_Allen in reply to LeeLiam

Yes. "In this study, the SoC is defined as a combination of Androgen Receptor Directed Therapy + Androgen Deprivation Therapy." Both arms get the SOC.

Fuzzman77 profile image
Fuzzman77

This sounds promising for those that haven’t done more than the 45 days of ADT. After the conversation last week about the guys that went to Delhi for it sure makes a lot of sense to try this in a trial. Best of luck for anyone able to access this trial.

IDK. The VISION trial included sites in Denmark, France, Holland, Sweden, and the UK.

45yrsDenmark in reply to Tall_Allen

Yeah, I know Denmark is also participating in the VISION... I will ask my MO.. Even though it will most likely not make sense for me (I am still hormone sensitive but have been on ADT for 14 months)..

pilot52 profile image
pilot52 in reply to 45yrsDenmark

India and Isreal accepted me for Lu-177. I am chemo naive and had a PSMA scan to submit. If you do not have access to PSMA scan they will do one on site. These are not clinical trials but actual therapy...It is a simple 5 step process to go to India and if you follow the steps it can be accomplished easily with in a 4 week time period. Charlie and I got it done it less than 10 days but it is a whirlwind process....just allow yourself some time we can help...Blue Skies Sky King and Penny (woof) Todays check...Charlie PSA 0.00 mine down to 0.42....and dropping

45yrsDenmark profile image
45yrsDenmark in reply to pilot52

Thanks for sharing. I can get PSMA PET/CT scans in Denmark where I live for free... It is just difficult to get them. As for Lu177, fortunately I can get them several places in Europe within 1,5 hours flight (e.g. Finland, Germany, UK, Austria) if I pay the whole things myself. But so far, I have un-detectable PSA (<0.10) and not very much PSMA showing on scans, and that is what Lu177 need, so at this point I don't think Lu177 is the way to go. I have a follow-up PSMA PET/CT in 3 weeks, so we will see how it looks. :-)

There are many questions that need to be addressed. India is currently a no-go due to Covid. They are now locked down...please message me if you are actually going to seek Lu-177. I need to know what home work you have done . I do not want to repeat what you may already know. Blue Skies.

AllenIt sounds to me that this early trial is an attempt to use LU-177 as an alternative to radiation.What are your thoughts?

Tall_Allen profile image
Tall_Allen in reply to Scout4answers

They allow SOC which includes prostate radiation if oligometastatic.

Scout4answers profile image
Scout4answers

Do you see LU 177 being used instead of radiation in the future if this trial is successful?

Tall_Allen profile image
Tall_Allen in reply to Scout4answers

Sorry, I have no idea what you're talking about. Radiation of what? Lu177 is radioactive.

Scout4answers profile image
Scout4answers

I read through the qualifications for this trial, they mention ADT and ARDT in standard of care but do not mention radiation treatments

As I understand Lu177( very limited knowledge so far) it inserts a radioactive isotope into cancer cels that have PSMA receptors and kills them. IMRT kills cancer cells with external radiation.

Do you see a way that LU 177 could eventually be used early in cancer treatment as an alternative to IMRT?

If not, why?

Tall_Allen profile image
Tall_Allen in reply to Scout4answers

You still didn't answer my question: radiation to WHAT? to metastases? to the prostate? I assume you mean to metastases since SOC currently includes prostate radiation for oligometastatic patients. If so, radiation will probably still be used palliatively on the larger metastases just as it is with Xofigo. I doubt that will change.

Prostate?

Tall_Allen profile image
Tall_Allen in reply to Scout4answers

The trial is for newly diagnosed men with metastases. They will all have intact prostates.

CAMPSOUPS profile image
CAMPSOUPS in reply to Scout4answers

I'll throw this at the wall. I had a little trouble understanding your question too.

For men who now prostatectomy or radiation of the prostate is recommended this treatment will not be replaced by Lu 177.

Lu 177 is for systemic, metastasized men.

Scout4answers profile image
Scout4answers in reply to CAMPSOUPS

Thanks for jumping in, sometimes I am not clear.MY question is: At some point could LU177 be used instead of external radiation in newly diagnosed men.

I ask this because it sounds like LU177 goes after all cancer cells where as Xofigo only goes after cancer in the bones.

Is this why Novartis is opening a trial for hormone sensitive men

CAMPSOUPS profile image
CAMPSOUPS in reply to Scout4answers

Well my pea brain will struggle to put an answer into words. Hopefully you can direct that to TA.One thing Lu 177 enters tumors to a certain depth so external is sometimes still needed.

Also it might be only anecdotal but it seems actually to work better on lymph nodes.

Scout4answers profile image
Scout4answers in reply to CAMPSOUPS

So it may work better on Lymphs. perhaps a better approach to get those micro mets than radiating the whole prostate bed with IMRT?

CAMPSOUPS profile image
CAMPSOUPS in reply to Scout4answers

Well ....above my pay grade as they say.There is a lot to consider.

For now it can in some cases be a good treatment for metastasized men.

It has not been good for others resulting in rapid progression.

Exactly who is left to the treating MO.
