藥華 P1101台大PhaseII收案20多名!!

台藥突破/國人自行研發長效干擾素 治BC肝副作用更少陳鈞凱 201394 12:49 政府扶植本土生技製藥產業多年,終獲突破性的成就!台灣 藥廠不再只侷限於學名藥的製造,現在也有能力製造新藥, 藥華醫藥在慢性肝炎以及骨髓造血細胞增生疾病等新藥研發上,能與國際知名大藥廠並駕齊驅。 更多照片 記者陳鈞凱/台北報導台灣研發肝炎藥物又有新突破。台大醫院和本土藥華藥廠攜手合作,針對國人自行研發的長效型α干擾素P1101進行第二期臨床試驗,初步結果,發現肝炎患者每2周施打一針,治療效果明顯,且毒性、副作用都比現行干擾素來的低,一旦人體試驗成功,將是第一個由國人自行研發的肝炎干擾素,還能治療血液疾病。由前經濟部次長尹啟銘一手催生的藥華醫藥今(4)天舉辦「10在感恩會」記者會以及罕見血液疾病研討會,正式宣布與中研院院士、台大醫院內科部教授陳培哲合作C肝治療的臨床人體試驗。治療肝炎,干擾素一向扮演重要的角色,陳培哲指出,干擾素的價格昂貴,中國大陸藥廠早已自行生產,但在台灣,迄今尚未有本土藥廠生產干擾素。健保署目前僅核准2家國際藥廠所製造的長效型干擾素用於治療B肝、C肝。陳培哲說,目前臨床以干擾素治療肝炎,患者必須每一周打一針,且因為副作用較大,容易疲累、掉髮,出現類似感冒症狀,並不好受,讓不少人心生畏懼,甚至聽到干擾素就拒絕治療。藥華自行研發的P1101則屬於單一化合物,純度超過95%,經動物實驗顯示,毒性極低,副作用也比目前的干擾素都要低,且長效劑量,只需每2周打一針,可望大幅提高用藥意願。陳培哲指出,目前P1101在台大進行第二期人體試驗,一共收案20多名、病毒量偏高需要治療的C肝患者,每2周打一針,再長期追蹤體內病毒量變化,初步觀察,治療效果很好。不只慢性肝炎,藥華醫藥董事長詹青柳表示,P1101也能用來治療血液疾病,長效性加上毒性低,一旦上市,對於血液疾病患者來說,將是一大福音,也會是國內製藥界的一大里程碑。

  1. 這並非是突破,藥華P1101仍舊是一個仿造羅氏藥廠PEGASYS的干擾素Biosimilar。在治療C型肝炎方面,目前國際藥廠的研發主軸傾向於避免干擾素使用(Interferon free)的全口服療程。所以P1101早就落伍了。臨床二期需要數千名試藥者,這點陳培哲自己也知道,卻只找來二十多人,裝模作樣。

  2. 1: peg 干擾素 有其既有f全球市場與適應症 2: 藥華pegylation 技術有其優於其他原開發廠之處 (higher purity) 3: C型肝炎治療 有新方向 但 藥華的臨床與量產 (& CMC) 屬策略性布局 有其後續階段性目的 !!
    PS ...estimated thousands patients (or enrollment) is not required for a ordinary phase II, fyi

    1. Can "higher purity" be translated into better efficacy? safety? clinical compliance, etc? or making it more business sense?

    2. GOOD point.....!
      Is higher purity associated with more predicted PK or blood circulation and market positioning? Anyway, thanks your insights and reminder!!

    3. Is this a "yes" applied to PEC's product?? Market position?
      watch out!! more oral and interferon-free HepC drugs are coming and they are working fantastically. How is the market sense then for IFN therapy in HepC treatments? Forget the market sizes for orphan drug! FYI

  3. really tough thoughts, and there should be more professional investors or outsiders to review other eye-catching company (and projects) on listing market. As for the company you mentioned (Gilead), developing small molecular drugs for HIV is also its strength, how about if......

  4. 羅氏PEGASYS 原廠品牌 已上市超過10年
    藥華P1101 Copycat 至少5年後才上市
    You get the picture!

    1. More exciting news for oral, interferon-free HepC drugs, FYI:

      ...-as doctors warehouse their patients in anticipation of a new standard of care that will eliminate the need for interferon, which often has harsh side effects...

      Got that picture? A product's "purity" alone is hardly a selling point.!!

    2. agree it, however, 藥華 intend to prove the protein drug production capacity and clinical trial elavuation,....

  5. 藥華B/C型肝炎新藥根本沒有市場! 就連PEGASYS的銷售也已經開始下滑 因為口服藥物要在今年12月被FDA批准 Sales of Pegasys (indicated for hepatitis B and hepatitis C) declined 19% due to the expected launch of triple-combination (second generation) and interferon-free therapies by 2013 end/ early 2014. Roche expects a continued decline in Pegasys sales going forward.
    大部分藥華的股東都不知道才會掉進這個錢坑 ! 願主保佑台灣投資人!

  6. 相信 藥華 有完整策略
    公司的經營 技術與策略取捨 都須考量

    專業投資者 應可從法說會 嗅出商機/錢味
    其他計畫(藥物) 可適用藥華技術平台 應也是未來布局
    關於"PEGASYS的銷售也已經開始下滑....." 公司應有Risk Assessment !!!
