KRAS G12C inhibitor sotorasib combined with pembrolizumab for KRAS G12C+ adv NSCLC led to prohibitive hepatotoxicity that required aggressive dose reduction of sotorasib. We've seen similar probs with some other targeted therapies combined w/immunotherapies.

We welcome people's thoughts!
ADAURA data are consistently hyped as showing long-term DFS benefit rather than characterizing results accurately, which should be "DFS benefit erodes immediately & profoundly after prolonged treatment ends, but it's enough to prop up DFS overall, for now (& don't ask about OS)"
Several wks ago, I asked about whether anyone has stat/image capturing theprogress made in lung cancer over past few decades. That has been hard to find. This image is my attempt, & a bit crude, but plotting med OS w/so many developments in that time. Work in progress.

ADAURA is unfortunately a trial of 100% access to osi vs <50% access to osi among pts w/EGFRm+ NSCLC, not adjuvant osi for all vs osi for pts at relapse, as needed.
Clearly, if pts got anything other than osi at relapse, it means they weren't too ill, but got worse Rx.
Great week!! Approvals for RET fusion-positive & MET exon 14 mutation-positive NSCLC this week.

Let's be clear: OS results are neg for OS benefit in PD-L1+ NSCLC. If we're going to rely on smaller subgroups to highlight the HR of 0.43 for those w/high PD-L1, we should also note HR for OS was 0.95 (i.e., NO trend of OS benefit) for those w/PD-L1 1-49%.

concludes IMpower010 OS results good enough to use atezo, but we can't focus on subgrp analysis. 🤔OS results for PD-L1+ are neg thus far, only pos if you focus on PD-L1 high pts. You can't rely on subgroups to call trial pos, then say ignore subgrps.
#WCLC22
This has always been a pivotal study, but now, seeing PFS >14% higher 5 years out, 4 years after consolidation therapy has ended, IMO we should conclude this has truly moved the needle (A LOT) on cure rates in this setting.

⭐️ Important trial that didn't get much attention when presented last yr, but it will lead me to consider single-agent atezo more favorably in this pop'n. Notable that benefit of atezo over single agent chemo was seen even in pts w/tumor PD-L1 express'n low or 0.

Nice to see an insurance company held accountable for denying care.
Just wish it hadn't been for an intervention that is actually w/o evidence of superiority in nearly all settings in which it is used, 3x more expensive than conventional RT, & is market > data-driven.
I guess it is possible for insurance companies to be held liable for denying care.
In these cases, they classified proton therapy as experimental for certain Indications.
🤔
Sorry. Lest a hapless reader be misled by this, TMB is NOT a test that has ever been shown to improve outcomes in lung cancer management by using it, is not a standard of care now, & is still far more sizzle than steak.
Maybe different w/more data, but today hype >> good data.
I've said "ship has sailed" & results justify adjuv osi. However, IMO, you/we should give less 👏📣& openly acknowledge major, systematic ethical/scientific probs that compromise if not undermine ADAURA interpretation. We shouldn't just REWARD cheating that HARMS pts on ctrl arm.

This is exactly why I think it’s time to stop debating ADAURA as I think this will be widely adopted, and move on to answering important questions about the appropriate duration of therapy, and which patients truly need any treatment, indefinite treatment versus de-escalation
