Early results from REACH-EGFR trial of VRN110755, a mutant selective EGFR TKI, at #WCLC26 show activity in EGFR C797S (6/6 responses) with ctDNA clearance and early signs of intracranial efficacy. Most common TRAE was rash but no discontinuations due to TRAE in 67 pts.

Update from SOLARA trial of BH-30643, a macrocyclic, mutant-selective, CNS penetrant EGFR TKI at #WCLC26. In EGFR C797S, RR 45% (18/40) with DCR 88% and 63% of pts still on therapy. Low discontinuation from TRAE (3%) with only 1% pneumonitis. Has fast-track designation from FDA.

In Beamion LUNG-1 with zongertinib, 8 paired tissue results from pts with PD showed two acquired HER2 mutations: T862A and S783C. Notably absent were T798I (gatekeeper) and C805S (binding site). The acquired mutations not detected in plasma. #WCLC26@dplanchard

Early insights into resistance to HER2 TKIs in NSCLC emerged at #WCLC26. Zongertinib & sevabertinib now both approved as 1L+ treatment for advanced NSCLC with a HER2 TKD mt. While efficacy similar, these are distinct agents and we need to learn how to leverage those differences.

ASBM’s former chairman, Dr. Madelaine Feldman, participated in the first panel of yesterday's #AfPASummit26: “The bottom line in pricing needs to be brought back to the patient’s ability to access the medication. For example -Many times affordability could be achieved by allowing the patient to pay their cost share (co-insurance) on the lowest post rebate/discount price of the drug.—including by basing cost-sharing on the lowest post-rebate price, especially for Part B drugs." @MattieRheumMD@patientaccess@LADAOrg@GlobalCRC@WarOnCancer@CSROAdvocacy

Updates in 9/2026 NCCN NSCLC Guidelines: sevabertinib as 1L option for HER2 mt NSCLC & daraxonrasib (off label at 200mg daily dosing) added to consider in pts with KRAS mutant NSCLC. In phase I/II, post chemo-IO, RR ~ 42%, DOR ~1y. Worth pursuing if no access to clinical trials.

I remember Dr. @geoff_oxnard et al first uncovering this founder effect for EGFR T790M while I was still at @GO2forLungCancr. I am glad to see the work validated in a much larger cohort of individuals. Being from SC and with Scotch-Irish ancestry, it's of interest to me!
New research from @DanaFarber & @23andme analyzed genetic data from 3.3M+ participants, identifying a rare inherited EGFR mutation linked to dramatically increased #LungCancer risk. The findings build on years of research into inherited lung cancer risk that GO2 helped advance.

The significance of the new study published in Science for a founder effect of EGFR T790M in #lungcancer is that it built upon and validated a previous finding in a much larger cohort ascopubs.org/doi/10.1200/JCO…

TROP2-ADCs are emerging as a promising therapeutic option across multiple treatment settings in #NSCLC🫁
What do HCPs need to know about the efficacy and safety profiles and potential AEs of these treatments?
How can we optimise the treatment experience and improve outcomes for patients?

#WCLC26 Presidential Symposium Day 2
🔥#DESTINY-Lung04: First-line trastuzumab deruxtecan (TDxd) vs chemo IO in #HER2-mutant metastatic NSCLC.
🎙️@JuliaRotow
▶️ Median PFS: 14.3 vs 8.3 mo
▶️ HR 0.63; P<0.0001
▶️ ORR: 70.0% vs 44.5%
▶️ DOR: 13.7 vs 9.7 mo
⬆️ crossover
⚠️Grade ≥3 TRAEs similar 🫁Adjudicated drug-related ILD: 20.8%
👉🏽👉🏽TDxd is more active than chemoIO, competes w oral drugs in market w less chemo side effects
👉🏽👉🏽some caution about ILD but overall we have used this drug safely in 2nd line.

DESTINY-Lung04 at #WCLC26
In 1L HER2-mutant advanced NSCLC, T-DXd significantly improved PFS vs pembrolizumab + chemotherapy:
mPFS 14.3 vs 8.3 months (HR 0.63; P<0.0001)
ORR: 70.0% vs 44.5%
However, no OS benefit was observed at this analysis (29.3 vs 33.1 months; HR 1.15).
The first Phase 3 trial showing benefit of a HER2-directed therapy vs SOC in this setting.
@OncoAlert@GlopesMd@ManuelDomine@StephenVLiu@weoncologists@OpenMedKate
Amazing discussion and great to see so much data in this space!
Toxicity and drug access are the big points for patients right now.
Curious to see the mechanisms of resistance to each strategy, possible novel combinations (Ami+TKI), and sequencing studies!
