立普妥Lipitor - 輝瑞大藥廠
• Atorvastatin , marketed by Pfizer as a calcium salt under the trade name Lipitor, is a member of thedrug class known as statins, used for lowering blood cholesterol. It also stabilizes plaque andprevents strokes through anti‐inflammatory and other mechanisms. Like all statins, atorvastatinworks by inhibiting HMG‐CoA reductase, an enzyme found in liver tissue that plays a key role inproduction of cholesterol in the body.
• Atorvastatin was first synthesized in 1985 by Bruce Roth of Parke‐Davis Warner‐Lambert Company(now Pfizer). The best selling drug in pharmaceutical history, sales of Lipitor since it was approved in1996 exceed US$125 billion, and the drug has topped the list of best‐selling brandedpharmaceuticals in the world for nearly a decade until Pfizer's patent on Lipitor expired onNovember 30, 2011.
• Initial launch in U.S. in 1996.7
Pregabalin was discovered by medicinal chemist Richard Bruce Silverman (born May 12, 1946) atNorthwestern University in the United States. The drug was approved in the European Union in2004. Pregabalin received U.S. FDA approval for use in treating epilepsy, diabetic neuropathic pain,and postherpetic neuralgia in December 2004, and appeared on the U.S. market in fall 2005.

Pharmacyclics(藥圈圈)的BTK(Bruton's TyrosineKinase)抑制劑Imbruvica(ibrutinib)。此新藥(IMB)於2013年4月8日獲得突破性治療後,接著在2013年11月13日,2014年7月8日與2015年1月29日取得美國FDA核准於治療三種血液方面的疾病。藥圈圈並於2015年3月5日以美金210億(約新台幣6千4百億)賣給AbbVie。公司所有的價值,基本上來自於IMB,充分說明了選題精準,一個小分子藥物創造了奇蹟式的成功。
藥圈圈成立於1991年,在1995年10月24日正式上市(IPO),股價是美金12元,其主要技術並未取得階段性的成功,因此股價一路下滑到2008年時,低於1美元。造成奇蹟似成功的IMB是在2006年由Celera買來。但在臨床前研究階段並未創造任何令人興奮的價值,所以到2009年大股東道格(Duggan)收購更多藥圈圈股票時,股價仍在美金1.28元。直到IMB成功進入臨床Ⅰ/Ⅱ期,獲得初步療效, J&J於2011年用美金9.75億買下共同行銷權(co‐promotion)後,藥圈圈才開始享受成功的果實。AbbVie的收購(每股美金261.25元)。

May 23, 2017美國藥廠默克(Merck)的癌症新藥Keytruda,再度獲美國食品藥物管理局(FDA)核准。此次獲准的適應症,是用於治療含有MSI-H或是dMMR基因缺陷,而導致實體腫瘤的成人及兒童病患。這也是全球首個非針對腫瘤發生器官(癌症類別)治療的癌症藥物,該產品旨在改善病患的變異基因,以達到治療效果。這不但是癌症治療的新突破,也是精準醫療上的大躍進,對於藥廠而言,更是擴大了新藥開發的多靶點適應症。

James P. Allison - CTLA-4MD Anderson Cancer Center 是美國頂尖的癌症醫學研究
與醫療重鎮,艾利森(James Allison)1995年發現CTLA‐
4是T細胞抑制性受體。他的團隊隨即製造出阻斷CTLA‐4
活性的抗體,並且於1996年以動物實驗證明該抗體可以
排除小鼠體內數種腫瘤。其單株抗體藥物成功被研發,
經臨床試驗證明對末期轉移性黑色素瘤患者有顯著治療
效果,於2011年經美國FDA核准上市。(每三個星期注射
一次、一個療程總共注射四次的訂價約12萬美元。)
艾利森說,許多癌症可以預防,光是戒菸與健康的生活
方式,約可減少1/3癌症的發生,使用多重藥物是比較
有效的治療方式。
他說,黑色素瘤藥物即是併用阻斷CTLA‐4與PD‐1活性的
抗體,9成使用藥物的患者可延長2年壽命,比例相當高。51
1992年本庶佑的研究團隊發現PD‐1免疫抑制因子,72歲的本庶佑指出,他實驗室的一名學生意外發現PD‐1分子,花了10年的時間才了解PD‐1會抑制免疫系統發揮功能。
本庶佑的團隊在2002年開始進行動物實驗,發現這個方法在老鼠身上的效果非常好,於是說服日本製藥公司生產供人體使用的PD‐1抗體,將這個方法治療癌症病患。2006年開始進行臨床實驗,使用PD‐1抗體對轉移性黑色素瘤的治療成效良好。
Merck的抗PD‐1抗體Keytruda®(pembrolizumab, MK‐3475),於2014年9月通過上市。。 Bristol‐Myers Squibb抗 PD‐1抗體新藥 Opdivo®(Nivolumab),在2015年3月通過上市,一個月12,500美元(一年15萬美元)
本庶佑進一步說明PD‐1抗體的3大優點,首先不同於多數治療癌症的藥物只針對指定的癌症,PD‐1抗體治療法可用於不同種類的癌症,目前已被使用到超過80種惡性腫瘤的病例,都發揮治療的效果。
第2項優點,多數癌症的化學治療都有副作用,因為他們多是有毒的化學物,但PD‐1抗體是要促進人類體內的免疫系統,目前僅發現有少數自身免疫的副作用,如結腸炎、肺纖維化是主要的副作用,但只要停止使用PD‐1抗體治療,病人就可以恢復。
第3項優點,一旦注射PD‐1抗體腫瘤開始萎縮後,效果可以維持數年,腫瘤都不會再變大,臨床實驗證明,人體的免疫系統一旦被啟動,就會持續攻擊腫瘤。

諾 華 ( Novartis ) 的 CAR-T ( chimeric antigen receptor T cell ) 療 法 產 品 Kyrmiah(tisagenlecleucel)於 2017 年 8 月 30 日獲得美國 FDA 核准,是全球第一款核准的 CAR-T 療法,為癌症治療開啟了新的里程碑──「以基因改造的免疫細胞為基礎」的治療模式。 Kymriah初期由美國賓夕法尼亞大學開發,並於 2012 年 8 月將全球商品化開發的權利授權給 Novartis。急性淋巴性白血病(acute lymphoblastic leukemia,ALL)一旦復發,能有的治療手段包含化療藥物、造血幹細胞移植(HSCT)等但效果有限,特別是在兒童與青少年這個族群,顯示出 r/r B-cell ALL 有高度未滿足需求。Novartis 公布定價為每次治療 475,000 美元,背後包含 Novartis 希望達到的銷售收入及 Kymriah製造成本、研發成本攤提、REMS 執行、長期藥物治療後追蹤成本等,並以 Kymriah 療效相較其他療法例如幹細胞移植(350,000~800,000 美元)而言是合理價格來對外宣稱。
