美国已获批,中国也有望上市的乳腺癌新药!相比化疗,治疗效果竟然翻了约2倍……

• 国内申请上市已获CDE受理;
• 解放军总医院江泽飞教授作为主要研究者的IIIb期CAPItrue研究已经正式启动(CTR20242809)!
CAPItrue研究如果成功意味着什么?
01
卡匹色替与CDK4/6抑制剂耐药的中国乳腺癌患者

揭秘HR , HER2-乳腺癌患者耐药之谜
PAM通路有三个关键分子,分别是PI3K、AKT和mTOR。
PIK3CA/AKT1/PTEN基因突变可使PAM信号通路异常激活,从而导致HR阳性乳腺癌CDK4/6抑制剂和内分泌治疗耐药。
卡匹色替是首款AKT抑制剂,也是CDK4/6抑制剂耐药后的新选择

卡匹色替为什么是CDK4/6抑制剂耐药后的新选择?
哪里能买到卡匹色替?

02
我想用卡匹色替,需要做基因检测吗?
激素受体阳乳腺癌患者无论是早期还是晚期,内分泌治疗都是基石,PAM信号通路异常激活是我们熟知的内分泌治疗耐药的原因,并且其异常激活也与CDK4/6抑制剂耐药密切相关。
举个例子,CDK4/6抑制剂联合内分泌治疗的一线治疗PFS通常约为2年左右,但相关临床研究结果提示,存在PIK3CA激活突变的辅助内分泌耐药患者接受CDK4/6抑制剂联合氟维司群治疗的PFS仅为7.3个月[10,11],这提示我们有PIK3CA激活突变的患者可能更容易对CDK4/6抑制剂联合内分泌治疗耐药,换个思路想想,这类患者可能用针对PIK3CA激活突变的靶向药可能效果更好。

展望与互动
如果有姐妹了解到哪里能买到卡匹色替,或者价格是多少,欢迎评论区分享!感恩信息分享互助的暖心姐妹!
