Phase 3 ended: ECLIPSE trial of 177Lu-PSMA-I&T

A phase 3 clinical trial called ECLIPSE has shown that 177Lu-PSMA-I&T significantly extends the median radiographic progression-free survival (rPFS) compared to hormone therapy in patients with PSMA-positive metastatic castration-resistant prostate cancer (mCRPC) previously treated with an ARPI (but I don't know which arpis were considered...will have to find out).

NOTE: rPFS was the first data to mature and from what I understand, median was 34 weeks, OS median not reached

The trial enrolled over 400 patients globally and included primary and secondary endpoints like rPFS, overall survival, and quality-of-life measures. The investigators also plan to conduct a substudy to assess pharmacokinetic and radiation dosimetry.

Hi Maxone, must say I am delighted to see the word 34 months but it also confuses me.Generally speaking once stage4 castrate resistant person got resistant with abi or enza, if pluvicto is applied median rpfs is 12-15 months, and I see frequent worst stories here.

Is this I&T version. Of LU 177 any different?

This 34 months, as I read it, looks like this is applied after patient got resistant with abi or enza or daro or...or it is applied as a first line on de novo metastatic patients?

Please enlighten me a bit.

Good news are sparse and hard to believe

34 weeks, but i am rrying to understand if I can find the actual complete data. I think the source is confused itself. You use it after the first line ARSI failed. What they say is that instead of switching to a different ARPI this solution is better. I must investigate more.

Well, it's not much different from pluvicto on that matter, but if it works on more people with less side effects...

Sounded like patients who had received ADT but no Xtandi, Zytiga, Daro, Erleada. Those are disappearing fast but I'm one of them.

Interesting. Pluvicto is only approved after chemo in US, I believe.

Not what you're looking for?
