Interest is growing in multispecific antibodies to target tumour types that are unresponsive to current #immunotherapy, as illustrated by #ClinicalTrials presented at #ESMO26 in #ColorectalCancer and #ClearCellRenalCellCarcinoma 🔗 ow.ly/Q2vW50ZZsq4 #InsightsbyESMO @MdCurioni

#keynoteB49- @myESMO #ESMO26 Adding ICB/ immunotherapy in advanced HR+ #breastcancer - wishful thinking 🤔 this context is immune deplete! -PFS 6-6.7 mo ➡️ Early high grade immune + HR + BC is the right place for it #ESMOAmbassadors
#ESMO26: Pembrolizumab plus chemotherapy reduced the risk of PFS by 26% in PD-L1-positive, HR-positive #AdvancedBreastCancer after failure on endocrine therapy in the phase III KEYNOTE-B49 🔗 ow.ly/5NoZ50ZZjCH #ClinicalTrial #BreastCancer #InsightsbyESMO @PTarantinoMD

🎉The only agent that can really increase pCR in a subset of early HR+ #BreastCancer is #ICB #ESMO2026 #ESMOAmbassadors
#ESMO26: Final results from the TALENT #ClinicalTrial show low pathological complete response rates with the antibody–drug conjugate (#ADC) trastuzumab deruxtecan in HR-positive, HER2-low #EarlyBreastCancer, as discussed by @breastDoktor #InsightsbyESMO ➡️ ow.ly/ZBwi50ZZXLm

How should immunotherapy be optimally applied for breast cancer? Excellent review of all the work being done in this field, and emphasis of the patient, not just the tumor, immune status (see Figure B below) @jclinicalinvest jci.org/articles/view/207634

Brillant summary 👏 thank you 🙏 @NeilVasan A paradigm changing decision and much food for thought @OncoAlert
Live tweeting on the @FDA AdComm on @GrailBio Galleri. Right off the bat CEO Josh Ofman emphasizing 1) the cancer types we *don’t* have screening tests for, 2) idea of cancer signal recognition independent of cancer type, 3) favorable risk/benefit mirroring voting question language, 4) concept of cancer yield, 5) adding Galleri to conventional screening
