结论摘要
Keytruda+Padcev的欧盟MIBC围手术期批准是44分钟前同一来源已处理事件的重复推送，无新增事实；属预期内程序性标签扩展，对超大市值MRK/Pfizer/Astellas增量微小且盘前未见正向重定价，多空均无edge。

消息传播链
- 同一欧委会批准消息已于11:53 UTC由本臂处理，结论不做（MRK.US/4503.JP/PFE.US），本条12:37 UTC稿件无新增事实市场反应:MRK周二收148.30美元（+3.25%），11:53记录时盘前约-0.44%
主要风险
- 若后续出现该适应症销售指引上调或美国FDA新决策等新增量事实，需作为独立事件重新研判，不适用本条重复消息的不做结论。
先例如何影响了这次决策
对本次决策的影响:因与72小时内已处理记录为同一具体催化且无新增事实，按跨源查重规则早停，未再展开外部先例检索

Merck (MRK) announced that the European Commission has approved KEYTRUDA (pembrolizumab) in combination with Padcev (enfortumab vedotin-ejfv) as perioperative treatment for adults with resectable muscle-invasive bladder cancer (MIBC), regardless of cisplatin eligibility.
The approval covers treatment before surgery, followed by continued treatment after radical cystectomy. It also includes KEYTRUDA SC, expanding the available treatment options for eligible patients across the European Union.
The decision was based on results from the Phase 3 KEYNOTE-B15 trial, in which the combination reduced the risk of event-free survival events by 47% and the risk of death by 35% compared with neoadjuvant gemcitabine-cisplatin chemotherapy and surgery among cisplatin-eligible patients. The pathological complete response rate was 55.8%, compared with 32.5% for chemotherapy.
KEYNOTE-B15 enrolled 808 patients and evaluated the combination against standard chemotherapy followed by surgery. The trial was conducted in collaboration with Pfizer and Astellas.
The approval authorizes the regimen across all 27 EU member states, as well as Iceland, Liechtenstein and Norway. Commercial availability in individual countries will depend on national reimbursement procedures.
MRK has traded between $82.01 and $156.92 over the past 52 weeks.
The stock closed Tuesday's trade at $148.30, up 3.25%. In the Pre-market, the stock is down 0.20% at $148.01.
