Perioperative Pembrolizumab + Trastuzumab with FLOT Achieves High pCR and Feasible Safety in HER2‑Positive Localized Esophagogastric Adenocarcinoma: Interim PHERFLOT Results

Perioperative Pembrolizumab + Trastuzumab with FLOT Achieves High pCR and Feasible Safety in HER2‑Positive Localized Esophagogastric Adenocarcinoma: Interim PHERFLOT Results

Interim results from the phase 2 PHERFLOT trial show a 48.4% pathological complete response and a 67.7% major pathologic response after four cycles of pembrolizumab, trastuzumab and FLOT in localized HER2‑positive esophagogastric adenocarcinoma; safety was consistent with known profiles.
