The present invention relates to methods for treating cancer comprising utilizing a combination of signal transduction inhibitors. More specifically, the present invention relates to combinations of so called cell cycle inhibitors with mitogen stimulated kinase signal transduction inhibitors, more specifically combinations of CDK inhibitors with mitogen stimulated kinase signal transduction inhibitors, more preferably MEK inhibitors. Other embodiments of the invention relate to additional combinations of the aforesaid combinations with standard anti-cancer agents such as cytotoxic agents, palliatives and antiangiogenics. Most specifically this invention relates to combinations of 6-acetyl-8-cyclopentyl-5-methyl-2-(5-piperazin-1-yl-pyridin-2-ylamino)-8H-pyrido[2,3-d]pyrimidin-7-one including salt forms, which is a selective cyclin-dependent kinase 4 (CDK4) inhibitor, in combination with one or more MEK inhibitors, most preferably N-[(R)-2,3-dihydroxy-propoxy]-3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-benzamide. The aforementioned combinations are useful for treating inflammation and cell proliferative diseases such as cancer and restenosis.
本发明涉及治疗癌症的方法,包括利用信号转导抑制剂的组合。更具体地,本发明涉及所谓的细胞周期抑制剂与促有丝分裂原刺激激酶信号转导抑制剂的组合,更具体地说是CDK抑制剂与促有丝分裂原刺激激酶信号转导抑制剂的组合,更优选地是MEK抑制剂的组合。本发明的其他实施例涉及上述组合与标准抗癌药物(如细胞毒性药物、缓解剂和抗血管生成药物)的额外组合。最具体地,本发明涉及包括盐形式的6-乙酰基-8-环戊基-5-甲基-2-(5-哌嗪-1-基-吡啶-2-基氨基)-8H-吡啶并[2,3-d]嘧啶-7-酮,这是一种选择性细胞周期蛋白依赖性激酶4(CDK4)抑制剂,与一种或多种MEK抑制剂结合,最好是N-[(R)-2,3-二羟基-丙氧基]-3,4-二氟-2-(2-氟-4-碘苯氨基)-苯甲酰胺。前述组合对于治疗炎症和细胞增殖性疾病如癌症和再狭窄症是有用的。
