“ESMO 2025 Day 4: Updates and New Combinations Across HR+, HER2+, and TNBC

Monday, October 20th delivered pivotal insights that will influence treatment sequencing decisions and introduce promising new agents to our armamentarium:

Key HR+/HER2- Advances:

  •  SONIA Trial OS Analysis: Important academic effort examining CDK4/6i sequencing showed no OS difference between first-line vs second-line use (47.9 vs 48.1 months). While these data provide valuable real-world insights, interpretation requires consideration of patient selection biases and cost-effectiveness implications
  •  CULMINATE-2: Novel CDK2/4/6 inhibitor culmerciclib + fulvestrant showed impressive PFS benefit (HR 0.56) with manageable toxicity in first-line setting
  •  PIKALO-1: LY4064809, a pan-mutant-selective PI3Kα inhibitor, demonstrated encouraging activity with notably lower class toxicities – only 1% Grade ≥3 hyperglycemia

Combination Strategies:

  •  SHR-A1811 + Pertuzumab: Impressive 77.3% ORR in HER2+ mBC with 91% 12-month PFS rate
  •  BEGONIA Update: Datopotamab deruxtecan + durvalumab achieved remarkable 79-81.8% cORR in first-line TNBC with manageable safety profile.”
