And then there were three. @TelixPharma gets approval for their 68Ga-PSMA-11 kit (called ILLUCCIX). Same clinical data as in the UCSF/UCLA prescribing information. Great to see that data lead to an approval of the agent that will be available more widely!
actually 41% PSA50 with 2/3 of those being PSA75. Not bad considering no PSMA selection, only single dose, and as you say, majority with prior LuPSMA. 6 with grade 1 xerostomia, 5 of whom had prior LuPSMA. Mutli-dose to start soon.
@PCF_Science#Prostatejc WCM has clinical data in an ongoing randomized multicenter trial of hi-risk M0 patients Rx with J591-Lu177 that is informative and impressive. Look forward to finishing [+/- 8 slots left] and releasing data.
@PCF_Science#Prostatejc Heterogeneity is a fact of life with all cancers esp PC. Itโs true of AR, PSMA, etc. PSMA is no more heterogen than AR; in fact the 2 are inextricably linked. Is heterogen so significant to abrogate clinical benefit? I think NOT.
@PCF_Science#Prostatejc Combining anti-AR + PSMA targeting is synergistic. Anti-AR increases PSMA and decreases DDR. Trick will be treating patients before they are end stage.

#prostatejc we did use folate-free media + supplemented with step-wise addition of folate from 0 to pharmacologic levels. In concert, we measured PSMA expression levels hoping to see rising PSMA in response to lowered folate. We saw flat PSMA across [folate]. Do you see otherwise
@jodebon #ProstateJC i agree. By hammering patients with potent ARis, we're driving them to an AR- state with an abysmal prognosis. PeterMac group has reported ultrashort survival in those pts who did not qualify for PSMA Rx.
#ProstateJC Can you quantify 'many'. I suspect these are the PSMA-/FDG+ cases described by Hofman et al. My recollection is this was around 17% in their series. Liver mets post abi/enz=>likely small cell/NET--AR-/PSMA-. Not surprising to me.
I suspect you're seeing a population skewed toward abi/enza failures; that may contribute to 'many'. Not surprising given the widespread use of abi/enz. Not likely good candidates for PSMA targeting.
