Animal tests on tumor drug finished Staff writer, with CNA A medical research team has completed animal testing on a drug that fights an aggressive type of brain tumor and found that the average life expectancy of mice doubled after they were treated, the leader of the research team said yesterday. Harn Horng-jyh (韓鴻志), a professor at China Medical University, said his team is working with a biotechnology company to develop a drug against Glioblastoma multiforme, which is an aggressive type of malignant primary brain tumor. The treatment of this kind of tumor usually involves surgery, radiotherapy and chemotherapy, but the drug aims to provide an alternative, Harn said. Lin Shinn-zong (林欣榮), chairman of the Taiwan Neurosurgical Society, said this type of tumor is fast growing and has a high recurrence rate. It can grow to 16 times its size in just one month and the life expectancy of patients, who are often not diagnosed until the late stages, is 12 to 18 months on average, he added. Harn said a steady release of the drug into the tumors inhibited their growth in mice. About 35 percent of the mice in the test lived for up to 250 days after one treatment and no side effects were seen during the experiment, Harn said. The main ingredient of the drug is z-butylidenephthalide, a natural compound that can be extracted from the Chinese medicinal herb Angelica sinensis, or Dong quai. There are about 400 new brain tumor cases every year in Taiwan, 60 percent of which are malignant, Lin said. The five-year survival rate of patients with malignant brain tumors is only 3.4 percent, he said.
長弘生技: 光麗生醫公司是一間長期投資幹細胞運用研究及細胞庫的公司,在一次偶然機會,遇到中醫大神經外科醫師林欣榮教授提及他的研究團隊 (中醫大病理部醫師韓鴻志教授及花蓮東華大學邱紫文教授…等等),共同開發一對抗人類惡性腦瘤新藥,以一個慢慢用釋放的生物載體釋放,此新藥及技術,已獲多國專利,目前已從事新藥臨床前試驗,這包含 CMC 合成新藥及藥動,藥毒等 FDA認證實驗,此際正是需求大筆資金之時候。 即使我早已知道新藥開發是一個漫長而且成功率相當低的不歸路,但我聽到林院長,娓娓道來他的團隊十年來,篳路藍縷,如履薄冰,在台灣生技產業,試圖作出第一個新藥的決心及使命感,生技產業不僅變成他們生命的一部分,感覺到更是他們的信仰,讓我十分感動。 組成的團隊主要是董事長周姵妏以及三位發明人分別為: 林欣榮教授、韓鴻志教授及邱紫文教授,他們均曾在美國進修,分別擁有 Stonybrook 大學神經生理學博士 ,Duke 大學病理學及 MIT大學生化工程博士。 這團隊主要人物 - 林欣榮院長,長期從事以幹細胞治療腦中風之臨床研究,有相當之成就,去年底並獲得2010年美國神經治療及修復學會最傑出研究獎,在頒獎大會上,主席介紹他一路走來,從法規面突破,經費募集之辛苦,技術人才之訓練不易,多少堅持才能走到今天之成就,奮鬥過程中的艱辛、困難,以致今天得以活躍在國際舞台上,聞者莫不禁為之動容。 其中邱教授還是東華大學學務長,她是一位非常傑出的女性科學家,又是美國麻省理工博士,生物載體部分就是她所研發,每次看她風塵僕僕從花蓮趕到台北開會,我就感到台灣充滿希望。韓鴻志教授是介於林院長臨床試驗和邱教授新藥基礎研究的整合者,他是個執行力百分之百的人。韓教授,林教授和我本人都是四年級中段生,我們一起目睹,且我本人更是参與了台灣電子業起飛,現在在台灣生技產業正處於方興未艾之際,我們更不願缺席這場盛宴,創造生技產業台灣第二個經濟奇蹟。這是讓我下定決心成立長弘生技公司全力支援這個團隊之主因。 新藥開發的生技產業需要高度的群落效應,可惜台灣現在這方面還沒完全建立。在這一年,我們一路走來,感恩有許多人的幫忙:這其中包括生物技術開發中心、核能研究所、台耀公司、莊哲仁顧問、陳璿如財務長,還有我們團隊中的閰思尹, 陳宣蓉小姐,沒有他們的參與,我們的新藥開發就不可能走到今天這一步。今年適逢中華民國辛亥建國一百年,想到當初黃興在武昌起義開了第一槍,締造了亞洲第一個民主國家,我們也希望在台灣的新藥開發,盡個人棉薄之力,参與領航者之一,讓台灣新藥開發躍上國際舞台。
