Can anyone share their experience with Pluvicto?

Posted by vcash @vcash, Apr 22, 2024

My 85 year old dad has prostate cancer that has metastasized to his bones. Zytiga is no longer effective. He is considering Pluvicto. I would appreciate input from those who have used Pluvicto.

Pluvicto can also affect healthy cells, particularly those that express PSMA, which is a protein found on some healthy cells as well as cancer cells. This can lead to side effects like low blood cell counts, kidney damage, and fatigue,

Thank you, I was just alerted to the risk to the kidneys by my wife. With chronic kidney disease I may not be a candidate if it comes to that. It looks like Xtandi with or without Lupron might be my best option to reverse PSA rise,

We were posting within 4 minutes of each other, your reply was not there when I started my reply, funny how that happens. Fortunately, we both supplied different information.

Great minds think alike! 🙂

Yes--this is an important addition to the information in the Mayo excerpt I just posted. Thank you, Jeff.

Has anyone heard information on whether the radiation of Pluvicto targets and damages healthy tissue as well the cancerous tissue? Asking because salvage radiation damaged my bladder and destroyed the urethra. Want to avoid a reoccurrence.

Pluvicto presents a much lower risk of radiation damage to healthy cells, because it is not a beam, but a molecule that targets only cells that express PSMA. Here is an excerpt from the Mayo entry about Pluvicto:

Treatments that target PSMA: Radiopharmaceutical treatments can target a protein that's common on prostate cancer cells called prostate-specific membrane antigen. It's also called PSMA. One radiopharmaceutical medicine that works in this way is lutetium Lu-177 vipivotide tetraxetan (Pluvicto). This medicine contains a molecule that finds and sticks to the PSMA on prostate cancer cells. The medicine also contains a radioactive substance. A healthcare professional gives this medicine through a vein. The medicine finds the prostate cancer cells and releases the radiation directly into the cells. It can treat prostate cancer anywhere in the body. PSMA therapy only works if the prostate cancer cells have the PSMA protein. Side effects include dry mouth, dry eyes, nausea and feeling very tired.

Be aware that 1/3 of people have really good results from Pluvicto, 1/3 Respond OK and 1/3 get nothing from it.

Pluvicto genetic issues
RB1, PTen, TP53 are Pluvicto resistant
ATM & BRCA work better with Pluvicto

Have you had a hereditary Test or a somatic test? It would be good to have both before having Pluvicto So you can see if you have a genetic conflict.

Some people have some major side effects from Pluvicto, most don’t. I have heard at least 5 people talk about their experience, In some cases they had to have more time between doses because of the side effects.

I saw a webinar where they discussed a person who lit up the Pet scan With metastasis from head to Legs. He had one Pluvicto Treatment and it almost cleared his pet scan, But his side effects were so bad that he could not take any more treatments

Interesting Pluvicto/PSA encounter after shot #3. My PSA went flying from 7 to 12. Just like that my hope deflated awaiting arrival of my PSA depression. My oncologist recommended stoping Pluvicto, and go right to scans and XTANDi. After he consulted with my Radiation Oncologist, Nuclear Oncologist, and other Oncologist, he/we/they came to the conclusion this looks like a PSA Flare. PSA Flares happen, the recommendation for the docs was to take one more injection, wait two weeks, do a Pet-Scan, and Bone scan and take it from here. This works well for me.

Anyone else have a PSA Flare-up while on Pluvicto?

My husband had all six Pluvicto infusions and didn't have a PSA flare, though he has had flares during and after other treatments. I know of other men who did have PSA flares during and after Pluvicto treatment. Most important is that you have had several oncologists analyze your situation and recommend that you have another Pluvicto infusion and then do scans two weeks after the infusion and decide on the path forward based on those results. It is terrific that you have had so many doctors consult on your case, and the recommendation they have made seems very reasonable. Good work by them, and by you! Good luck with your next steps.

I did not have a PSA increase after any of my Pluvicto treatments, but a few other patients in my group did. To my knowledge (within my group of 80 or so), almost all of these patients had an eventual PSA decline. My non-medical, but very experienced Pluvicto patient opinion, including being one of the original clinical trial guinea pigs, believes your doctor is going down the correct path to proceed with the next treatment, then test for results. Stay focused, informed and do what needs to be done.

I did not have a "flare up". Fortunately, my PSA improved from a failed chemo (2 doses) PSA @ 13 Each test after Pluvicto started was under 1. The PSA test a month after Pluvicto ended (6 treatments) was 0.11. Scans came back with the words "Remarkable improvement". I had a total turn around, but 3/5/25 my PSA had risen to 4.01 and I'm now on a different Chemo. Now looking for a 2nd Pluvicto Treatment, but not clear as to FDA approval which I'll need to have Medicare cover the substantial expense. Original diagnoses 2016, I'm 74 now and still active. Looking for other options......
