Real-World Analysis Supports Rethinking Upfront Dose Intensity of Enfortumab Vedotin in Advanced Urothelial Cancer @ScienceChow @PennCancer @Ron_cology @ramsedhom #blcsm hubs.ly/Q041HfMF0

💫🌟🚨 New real-world evidence on EV dose reduction in advanced urothelial cancer🌟💫 🎓 @JAMAOnc study shows that starting treatment with reduced-dose enfortumab vedotin in 1L EV pembrolizumab: 🔵 Cuts treatment interruptions by ~50% (better tolerability) 🔵 Maintains overall survival — no compromise on outcomes 🔵 Benefits remain consistent in older & physiologically vulnerable patients 💡 Take-home: “Start low, go slow” may be a safe and practical strategy to keep patients on therapy without losing effectiveness. jamanetwork.com/journals/jam… @OncoAlert @myESMO @ASCO @BladderCaJrnl @MedicalwatchHQ #BladderCancer #UrothelialCancer #OncoAlert #GUOncology #EV302

Among patients with advanced urothelial cancer, upfront enfortumab vedotin dose reduction was linked to a 50% reduction in treatment interruption risk but did not compromise overall survival. ja.ma/3Lw71JH

A retrospective cohort study led by @ScienceChow & team supports reducing the dose of the antibody-drug conjugate enfortumab vedotin when patients receive it as first-line therapy pembrolizumab for the most common form of bladder cancer. @ASCOPost spr.ly/60157h5QH

New study in #UrothelialCancer shows upfront lower-dose enfortumab vedotin (EV) pembrolizumab: 🔻 Lowered risk of EV interruption (HR = 0.49) ⏱️ Similar OS vs standard-dose EV 💡 Efficacy similar in vulnerable pts (80 , poor performance) 🔹@ScienceChow ascopost.com/news/december-2…

Early EV dose reduction in advanced urothelial cancer ↘️ treatment interruption risk by half, yet survival stayed the same. @JAMAOnc @OncoAlert @WorldBladderCan @Uromigos jamanetwork.com/journals/jam…

Today in @JAMAOnc, we share new real-world evidence supporting reduced-dose EV Pembro for 1st-line rx of advanced urothelial cancer (a dz of older adults) led by @PennCancer fellow @ScienceChow & @Ron_cology

Is there a synergistic effect between enfortumab vedotin (EV) and pembrolizumab (P) for untreated advanced urothelial carcinoma in clinical setting? This analysis suggests no! EV P seems to follow a an independent drug action model with no evidence of synergy

New @Nature_NPJ paper by @ScienceChow co-mentored w/ @KLNathanson @BasserBRCA on reliability of #deeplearning to predict variant pathogenicity. #AI recapitulate ClinVar classifications for pathogenic variants, but poorly predict pathogenicity for VUS's #breastcancer

Phenotypic Evaluation of Deep Learning Models for Classifying Germline Variant Pathogenicity @Nature_NPJ • This study evaluates the real-world utility of three state-of-the-art deep learning models—AlphaMissense, EVE, and ESM1b—in classifying germline variants associated with hereditary cancer risks. • Using data from 469,623 UK Biobank participants, the study focuses on missense variants in key cancer-related genes, including BRCA1, BRCA2, ATM, CHEK2, and PALB2. • AlphaMissense and ESM1b models were able to identify pathogenic BRCA1 and BRCA2 variants that conferred increased risk for breast and ovarian cancer, but they struggled with certain other genes like ATM and CHEK2. • Notably, AlphaMissense identified potentially pathogenic PALB2 variants, which were previously categorized as variants of uncertain significance (VUS) by ClinVar, hinting at the models’ potential for refining variant classification. • Despite their success with some genes, all models exhibited limited accuracy in distinguishing VUSs associated with increased cancer risk, underscoring the need for cautious interpretation in clinical practice. • Composite classifiers that combined ClinVar annotations with deep learning predictions reduced the proportion of participants classified as VUS carriers, though at the cost of predictive power. • The study highlights the importance of gene-specific thresholds, as a uniform cutoff reduced model accuracy across multiple genes, indicating that custom thresholds may improve performance. • The authors emphasize the need for diverse genomic data to mitigate biases in current models, especially since VUSs are more prevalent in non-European populations. • While the study shows promise for integrating deep learning in clinical settings, it concludes that deep learning models are not yet ready to fully replace traditional variant classification methods for clinical decision-making. @ravi_b_parikh @KLNathanson @ScienceChow 💻Code: github.com/rdchow/UKB_pathog… 📜Paper: nature.com/articles/s41698-0…
