#ESMO26 Dr. @RobertoFerrara_ explains next-generation immune toxicities seen with next-generation immunotherapies. Rational design of SCORPION vs CRAB antibodies is a good example of intentional design to address toxicities. Very helpful overview. #ESMOAmbassadors

Savo + Osi >>> Osi
In 1L stage IV, EGFRmut: Better PFS and remarkable 44.5 OS for a poor prognosis population, with the cost of more MET-related side effects.
High attrition to find MET-IHC3+. Wondering how this data compares to this subset of patients in the MARIPOSA trial. #ESMO26 #LCSM

ESMO 2026 | A cautionary tale for immunotherapy de-escalation!
MOIO Trial (LBA10) – Phase III non-inferiority trial testing 3-monthly immunotherapy vs standard dosing in responding patients with advanced/metastatic cancer.
📊 Key results (N=308):
• Median PFS: 21.9 vs 25 months (reduced vs standard; HR 1.35)
• Risk of death: HR 2.0 (95% CI 1.1–3.9; p=0.0143) ⚠️
• PFS HR in urothelial cancer: 2.9
• Grade 3–4 immune-related AEs: 9.5% vs 10.5%
❌ Non-inferiority NOT demonstrated.
❌ No meaningful safety advantage.
⚠️ Signal of inferior survival with reduced-frequency IO.
💡 Take-home: Less frequent immunotherapy is not necessarily equally effective!
Important: These are interim results with relatively small numbers and heterogeneous tumour types.

Pembro monotherapy still has a role in selected pts (borderline ECOG PS or where a pt does not want to do chemo) but the control arm did not underperform. The final median PFS for Pembro mono in KN024 was only 3 weeks less than the control arm performance in PERSEE was it not?

Brilliant discussion from Dr. @BenjaminBesseMD at #ESMO26 on the Krascendo 1 study of divarasib vs sotorasib/adagrasib. Rightly points out lack of crossover in a study with a PFS endpoint as unjust. Excellent points all around. #ESMOAmbassadors

No information by molecular subtypes (eg KRAS mut) or elderly patients where combination may be not necessary or even detrimental because of side effects.

‼️ In first line treatment of advanced PD-L1 ≥50% NSCLC, PERSEE demonstrates a significant improvement of PFS with pembro-CT compared to pembro monotherapy regardless of PDL1 level of (over)expression. Practise changing trial. @myESMO @OncoAlert #ESMO26 👏👏👏 @decroisette

DeLLphi-305 - tarlatamab added to durvalumab after initial chemo-immunotherapy for small lung cancer essentially doubles survival. Hope for all cancers here, if the right target & treatment modality can be refined. Unquestionably a new standard for this disease. #ESMO2026

🫁 PD-L1 ≥50% has long supported pembrolizumab monotherapy — but PERSEE asks whether some of these patients should receive more upfront.
@OncoAlert
At #ESMO26, phase III PERSEE compared pembrolizumab + platinum-based chemotherapy versus pembrolizumab alone in first-line advanced #NSCLC with PD-L1 ≥50%.
📊 n=321
➡️ Median PFS: 16.1 vs 6.9 months
HR 0.56 (0.43–0.74), p<0.001
➡️ Median OS: 50.2 vs 29.9 months
HR 0.77 (0.57–1.05)
➡️ ORR: 77.5% vs 50.3%
But the trade-off is substantial:
⚠️ Grade ≥3 TRAEs: 53.8% vs 19.3%
🎯 Why this matters: PD-L1 ≥50% may not be enough, by itself, to decide between pembrolizumab alone and chemo-immunotherapy.
For me, the real clinical question is now:
Which PD-L1–high patients need the deeper and faster disease control of chemotherapy upfront — and which can safely avoid the added toxicity?
That is where tumor burden, symptoms, pace of disease, comorbidities and better biomarkers will matter most.
Excellent work from @decroisette @BenjaminBesseMD @LGreillier @C_Ricordel @FGuisier and the PERSEE investigators.

🫁 Phase 3, open-label (n=321): pembrolizumab + platinum-based chemotherapy vs pembrolizumab alone, first-line advanced NSCLC with PD-L1 ≥50%. Primary endpoint: PFS by blinded central review.
➡️ Median PFS 16.1 vs 6.9 mo; HR 0.56 (0.43–0.74); p<0.001
➡️ Median OS 50.2 vs 29.9 mo; HR 0.77 (0.57–1.05); ORR 77.5% vs 50.3%
➡️ Grade ≥3 TRAEs 53.8% vs 19.3%
✅ Pembrolizumab-chemotherapy significantly improved PFS vs pembrolizumab monotherapy and may help refine treatment selection. #NSCLC #LungCancer
