#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‼️ Image

#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❓

#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 Image
@TumorBoardTues @ASCO @JohnEbbenMDPhD @SushmaJonna @HeekeMd @pashtoonkasi @KReissMD @DrR_DUNNE @FogacciJoao @AJacomeMD @OncBrothers @oncologician @DrSteveMartin @stolaney1 @ErikaHamilton9 @hoperugo @BreastCancerMD1 @FilipaLynce @DFCI_BreastOnc @BreastCaupdates #TumorBoardTuesday

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 Image

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 Image

#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? Image
@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 Image

📢In preparation for #ASCO22, I wanted to present my list for the #PancreaticCancer abstracts to👀for @ASCO

Again,🙏note - I went through a LOT of abstracts, and I definitely may have missed some‼️
👉And these are not in any particular order

✅But enjoy, RT, and reply😀
#ASCO22 #PancreaticCancer
🤔Is more better❓
✅Dr. Carrato🧑‍🏫a Rand trial
👉Gem-nab-pac➡️FOLFOX (sequenced Q6 wks)
vs.
👉Standard Gem-nab-pac
➡️mOS was 3.5mos⬆️with sequenced Tx
➡️Even though more standard pts got 2nd line Tx
🤯Really❓
🤔Interesting
🔎GI Can Oral Abst 4022
#ASCO22 #PancreaticCancer
🤔Is more better❓
✅Similarly, Dr. Portalesa🧑‍🏫a Rand Ph2 "Trial in Progress" comparing:
👉Sequential gem-nab-pac➡️FFX
vs.
👉Standard FFX alone
➡️Primary objective is OS
🤔But really, what will be critical will be the OS

Case 08/03/21

74 yo♂️presents with RUQ pain and fatigue, 30# weight loss, PS=2

CT scan demonstrates a large panc mass and diffuse liver metastases

Liver core biopsy confirms an acinar cell #PancreaticCancer

➡️What would be your treatment recommendation❓
@ShimaghavimiMD @TumorBoardTues #TumorBoardTuesday
08/03/21

He was treated with every other week Gem-nab-pac
🙏@GIcancerDoc
➡️Had rapid symptomatic improvement
➡️Now essentially normal PS
➡️Nice response to treatment for 9 months🙂

But then disease progression❗️

What would be your 2nd line therapy choice❓
@ShimaghavimiMD @TumorBoardTues @GIcancerDoc #TumorBoardTuesday
08/03/21

Germline NGS🧬testing did not reveal any inherited alterations

☝️Somatic (tumor) NGS🧬testing revealed a
💥BRAFV600E mutation💥

✅And no KRAS mutation

➡️Done while on 1st line therapy

Would the results alter your treatment choice now?

#ASCO21

🙏Thank you all for the positive feedback on the PDAC Abstracts

➡️Here now is my 2nd list
✅My Top NON-Pancreatic abstracts to watch for...in no particular order.....

📝Again, I tagged who I could (whose hashtag I could find)
#ASCO21

There were several potential practice changing studies including the one Late Breaking Abstract teaser:

➡️I Chau, et al (LBA 4001)
✅Nivo + ipi or Nivo + chemo vs. chemo alone as 1st-line Tx for esophageal SCC: CheckMate 648

🧐Will dual IO be the winner❓
#ASCO21

➡️R-H Xu, et al (abstr 4000)
✅Ph 3 trial of camrelizumab plus chemo vs. chemo in patients with advanced esophageal SCC
👉Paclitaxel + cis +/- camrelizumab
👉596 patients randomized

🎉Camrelizumab plus chemotherapy⬆️mOS (15.3 vs. 12.0 mos) and ⬆️ORR (72.1% vs. 62.1%)

#ASCO21 #PancreaticCancer

📢ASCO is a few days away, and I decided to put together my list of
✅Top Abstracts to watch for

📝I tagged who I could

Starting with my Top Pancreatic Cancer Abstracts...in no particular order.....

(A common theme: NGS and fusion testing is🗝️)
#ASCO21 #PancreaticCancer

@VivekSubbiah, et al (Abstr 3079)
➡️RET inhibitor pralsetinib in patients with RET fusion-positive solid tumors

I know - he has presented this before🙄

🥳but now 3/3 patients with pancreatic cancer responded - one with a CR ongoing at 20.8 months‼️
#ASCO21 #PancreaticCancer

Alison M. Schram, @EileenMOReilly @graokane @benweinbergmd (abstr 3003)
➡️Zenocutuzumab (MCLA-128) in pancreas cancer and other solid tumors harboring NRG1 fusions

✅INV-assessed ORR = 40% (4/10)
✅Tumor regression in 7/10 pts
✅DCR = 90%
✅DOR TBD

Thursday Case 🎀

🧑‍🎓Great discussion on the Tx of LAPC

✳️Most preferred FFX for this pt

➡️But the only PROSPECTIVE 📋 is w/gem-nab
pubmed.ncbi.nlm.nih.gov/30220407

➡️There are ✅ retrospective 📋 for FFX
thelancet.com/journals/lanon…

➡️For both, resection rate is 10-15% Image
@TumorBoardTues #TumorBoardTuesday
Thursday Case 🎀

Other options for LAPC:

➡️Clinical trials should be our 1st option, if available
✳️TIGER-PAC
✳️KRAS G12D/V siRNA + chemo
✳️Gem-Nab +/- FG-3019

➡️Radiation (despite negative data from LAP-07)

➡️IRE
✳️2 abstracts @ASCO #GI21
@TumorBoardTues @ASCO #TumorBoardTuesday
Thursday Case 🎀

We had a poll on what is essentially 2nd line chemo for LAPC
✳️Not surprisingly most recommended gem-nab

➡️There are 2 abstracts @ASCO #GI21 on using nal-iri after progression on FOLFIRINOX

Any thoughts on this?🤔 Image

@TumorBoardTues #TumorBoardTuesday-1/7

📣 51 yoF presents with abdominal pain

FH – Father with lung cancer (🚬)

Imaging 📷 showed a 2.9 x 2.6cm panc head mass encasing the SMA

EUS-FNA 💉 - Well-diff adenocarcinoma

➡️Dx: locally advanced unresectable PDAC

❓How you would Tx this Pt?
@TumorBoardTues #TumorBoardTuesday-2/7

Case Follow Up

Patient treated with FOLFOX + SBRT ⚡️
Then maintenance capecitabine
✅(SDz for 2 years!) 👍

Eventually progression with a right ovarian metastasis

❓Poll: Now how would you treat the patient?
@TumorBoardTues #TumorBoardTuesday-3/7

Additional details - NGS DNA Testing 🧬

Somatic tumor testing – pathogenic ATM mutation❗️

Germline testing – no germline ATM mutation

➡️ Share how this information would change your treatment plans 🤔
