@jlberrymd Nice thread. Given each step from frontline metastatic β> 3L+ therapy corresponds with lower ORR and also with poorer PS, I imagine in later lines of therapy, the marginal benefits seen in trials with PS 0-2 are probably erased with PS 3-4. But worth considering in frontline
@VPrasadMDMPH@HOJournalClub@GlendaDelgadoR OS is 2ndary endpoint in POLO (data 46% mature), but given the control arm and generalizability of trial, even if significant OS diff, not sure how to incorporate olaparib in panc. I guess question is IF/WHEN olaparib can be used in BRCA+panc and how to study? #HOJournalClub
@HOJournalClub@VPrasadMDMPH I think whenever there is a line such as "IMspire150 was a randomised... study done at 112 institutes in 20 countries" one has to carefully examine what was the next line therapy given to those in experimental vs control arm (esp if its reflective of current US practice)
@VPrasadMDMPH@HOJournalClub So there was a mandatory washout time / treatment interval of 4-8 weeks.
RR was 23% in olaparib group and 12% in placebo group. I suppose you could get some RR in the form of placebo but one wonders if there is residual FOLFIRINOX effect? #HOJournalClub
@DevikaDasMD@HOJournalClub@VPrasadMDMPH Seems like generalizability to clinical practice will be limited. Likely will be a difference between population that was studied vs what it will be marketed as / extrapolated to in clinical practice. #HOJournalClub
@HOJournalClub@VPrasadMDMPH Echoing what others are saying here. Table 1 shows that 50% of patients had stable disease following frontline chemotherapy. Odd that these are then randomized to more treatment (olaparib, which is presumably active as a monotherapy here) vs no further treatment
