Should we infuse IO in the morning? Intriguing work just published: Circadian tumor infiltration and function of CD8+ TĀ cells dictate immunotherapy efficacy. We may need to analyze timing of IO infusion in phase III trials to guide us in our daily clinic. cell.com/cell/fulltext/…

Two new studies support the hypothesis that pts with EGFR mutated NSCLC are the best population for TROP-2 ADCs: EVOKE-01 (EGFR is in the ā€˜AGA’ subgroup in the forest plot) and ICARUS-LUNG. d.planchard EGFR Resisters #ASCO24

Pr Egbert Smit elegantly suggests that TROP-2 ADCs with a topo-1 inhibitor payload (deruxtecan, govitecan…) are not better that old fashioned topo-1 inhibitors such as irinotecan or topotecan.

S/C route is the way to go for amivantamab! Paloma 3 trial shows similar PK of S/C vs IV with potentially better survival. Dose intensity & toxicities seem similar (but for Infusion relation reaction). Are blocking ADAs (anti drug antibodies) more frequent with IV vs S/C? #ASCO24

Important and completely counter intuitive study ! The NGR-LU002 stydy shows that the irradiation of all sites (primary+mets) after induction chemo or chemo-IO does not increase survival compared to the standard maintenance treatment. « Le mieux est l’ennemi du bienĀ Ā» #ASCO24

For pts w EGFRm with Osi-Progression NSCLC not homogeneous benefit in PFS with🩸antiangiogenic + io+CT vs CT and no mature OS benefit Ph 3 HARMONI-3 trial (ivonescimab (bispecific VEGF/PD1 Ab)+ CT vs CT is pending. Data in Chinese pts looks similar to previous (HARMONI-A) #ASCO24

Lorlatinib PFS is impressive with an HR 0.19 over crizotinib. But why after 5 yrs FU can’t we see the OS curves and the cross over rate? Even if the number of events is not reached, that would help us to select our first line treatment. ALK Positive #ASCO24

1st generation KRAS inhibitors: a piece of the puzzle is still missing. #ASCO24 Hope it will be enough to convince refractory HTAs to refund the drug! KRASKickers

LIFETIME osimertinib after a treatment with curative intent? In pts with EGFRmut stage III NSCLC, chemo-radiotherapy can CURE pts. Were pts in LAURA properly staged by petscan/brain RMI? Why not using MRD to select patient? Strong concerns when OS is not positive. #ASCO24

Stop pembro after 2 years? In 43,359 pts that received up-front pembrolizumab for an advanced NSCLC, continuation beyond 2 years was not associated with better OS than a fixed 2-year treatment, HRĀ =Ā 0.97 [0.75–1.26] pĀ =Ā 0.95. Adrien Rousseau sciencedirect.com/science/articl…

Adjuvant Durvalumab after resection of stage IB~IIIA NSCLC does not improve DFS. No predictive effect of PD-L1 expression as in KN-091/PEARLS (adj pembro): Biology of micrometastatic disease differs from matched primary tumor? Confirms that neoadjuvant is the way to go. #ESMO24

Impressive benefit for Lenvatinib-Pembrolizumab in pts with thymic carcinoma and B3 thymoma. ORR 23.3% and mPFS 14.9m are unexpected in 2nd line or more. Lenvatinib dose matters in a subgroup analysis. Congratulations Jordi Remon #ESMO24

YES! De-escalation trials matter and should be much more supported by payers! Very preliminary results from the Dutch non inferiority trial DEDICATION-1 are reassuring. In France, the PULSE trial has the same hypothesis, opens soon in Belgium, Spain, Estonia and Greece! #ESMO24

NUT Carcinoma is an ultra-rare entity with a NUTM1 fusion, diagnosed by a simple IHC NUT+ (can look like a squamous lung cancer in a never smoker pt). Previously known as midline carcinoma, its prognosis is extremely poor. Lurbinectedin appears promising! annalsofoncology.org/article/S0923-…

ICB or chemo-ICB in PD-L1≄50% advanced NSCLC? Metabolic tumor volume (tMTV) assessed by 18F FDG petscan can guide you. High tMTV lesions might have a different biology and be better candidate to chemo-ICB. Filippo Dall'Olio aacrjournals.org/clincancerres/…

Debate on L1 for EGFR mut NSCLC : ā€˜easy osi’ then escalate to CT-ami, or use doublet upfront? Lazertinib+amivantmab likely to extend OS by ~ 1 yr vs osimertinib, but without cross over to CT-ami. Intensify only if ctEGFR not cleared after 4w of osi? #ELCC25
