#ASCO22 Biomarker Recap

😀Don't know about you all - but I had a great time at the meeting this year!

👉I will🔦a few biomarker based studies that caught my👁️

😉Did you notice that TWO of the plenary abstracts were for biomarker based trials‼️

#1⃣
✅Dr. Yoshino🧑‍🏫the results of the Ph 3 PARADIGM trial
➡️FOLFOX-Pani vs. FOLFOX-Bev for RAS WT left CRC
👉823 Pts

👏OS>with Pani 36.2 vs. 31.3 months
👏ORR also > with Pani 75% vs. 67%

🤔BUT the curves don't separate until 26 months❓

🔎Abstract #LBA1

#2⃣

✅Dr. Modi🧑‍🏫the results of the Ph 3 DESTINY-Breast04 trial
➡️T-DXd vs. SOC for HER-2 low metBreast Ca
👉557 Pts

👏PFS>with T-DXd 10.1 vs. 5.4 months
👏OS also > with T-DXd 23.9 vs. 17.5 months

🔎Abstract #LBA3

These are clearly two practice modifying abstracts:
👉Use an anti-EGFR + chemo front line for a RAS/RAF WT met CRC
👉T-DXd is better than standard chemo in HER-2 low breast cancer

#3⃣

(I missed this in the pre-review)
✅Alison Schram🧑‍🏫a trial of zenocutuzumab, a HER2 x HER3 bispecific Ab for NRG1 fusion+ Ca
👉73 assessable Pts
👉Mostly NSCLC & PDAC

ORR = 34% (42% in PDAC)
Median duration of response = 9.1 months

🔎Abstract #105

But in fairness...
✅Daniel R. Carrizosa🧑‍🏫a trial of seribantumab, an anti-HER3 mAb in NRG1 fusion+ Ca
👉Only 10 assessable Pts
👉3/10 responded

➡️So this appears to be a class effect

🔎Abstract #3006

#4⃣

👇HER3 is a legitimate target
✅Ian E. Krop🧑‍🏫a Ph1/2 trial of patritumab deruxtecan, a HER3-directed ADC in pts with HER3 expressing Breast Ca

👏Out of 113 patients, the ORR was 30%

🔎Abstract # 1002

🤔I don't see a follow up Ph2 or Ph3 study though?

@TumorBoardTues @ASCO @JohnEbbenMDPhD @SushmaJonna @HeekeMd @pashtoonkasi @KReissMD @DrR_DUNNE @FogacciJoao @AJacomeMD @OncBrothers @oncologician @DrSteveMartin @stolaney1 @ErikaHamilton9 @hoperugo @BreastCancerMD1 @FilipaLynce @DFCI_BreastOnc @BreastCaupdates @EileenMOReilly @graokane @benweinbergmd @alexdrilon @DCarrizosaMD @LevineCancer @PTarantinoMD #TumorBoardTuesday

HER3 is also a🎯in Lung Ca
✅Dr. Steur👨‍🏫Ph1 trial of Patritumab deruxtecan in NSCLC
😮BUT the predictor was NOT⬆️HER3
➡️It was a driver🧬alteration
👉e.g. K/NRAS/EGFR/ROS/ALK
➡️ORR in the driver group = 35%
🔎Abstract 9017

AND - several F/U trials in Lung Ca
