(沈富雄, 專業質疑! ) 浩鼎OPT-822/OPT-821何以提早解盲?(張念慈: 專家決定!!)

張念慈解釋浩鼎解盲 沈富雄仍質疑 2016-03-30 03:01 聯合報 記者胡宥心、鄭宏斌、黃文奇/台北報導 民進黨前立委沈富雄昨天表示,浩鼎生技董事長張念慈昨天致電給他,提到二月初送到美國腫瘤醫學會ASCO的報告是空白,解盲後才補齊數字,結論也要修改,他對此很訝異,「是否這也是不得不解盲的原因,我實在沒有搞懂」。 浩鼎董事長張念慈則表示,提前解盲是專家會議決定,且送給ASCO僅是報告摘要與架構,非解盲數據。沈富雄前天在叩應節目中提浩鼎兩質疑,包括:未解盲怎敢寫報告到ASCO發表?為何提早解盲、解盲後的結果又在哪?並要求張念慈昨早說明。沈富雄昨受訪表示,張念慈回覆,送報告時數字是空白的,解盲以後才把數字補上,沈反問:「這樣結論是否要修改?」張說:「是的。」沈表示,這讓他很不可思議,因為據他了解,所有有分量的美國醫學年會,很少有兩次截止日期,浩鼎竟然可以這樣做。沈富雄昨晚繼續在節目中說,如果是病人減少,那實驗應該要延長而非提早,且要蒐集新的病人,「顯然公司決策單位很急」;沈也質疑,提早解盲是否根本是為了發表文章?「你們(浩鼎)覺得社會誤會你們,其實你才欠社會公道」。張念慈指他的說明完整,沈應該已經了解,但沈卻認為「疑慮仍沒澄清」。張指出,雖然浩鼎未能在二月二日前提出完整試驗數字,但ASCO通常保留另一管道,讓公司先遞交論文摘要架構,最遲須於三月十五日前將完整內容送達;當時OBI-822已經解盲,因此再補上最新數據。至於何以提早解盲?浩鼎強調,設計之初是以復發人數達二八九人為解盲標準,如今試驗已進行五年半,復發人數仍遠低於此一解盲標準,對繼續試驗服用安慰劑的受試者並不公平,才於去年八月聽取專家意見後,決定八月卅一日公告今年三月解盲。

沈富雄質疑浩鼎案 張念慈動怒 2016-03-29 08:27 經濟日報 記者黃文奇╱即時報導浩鼎案引來「百家爭鳴」,民進黨前立委沈富雄昨天在叩應節目中,質疑浩鼎新藥為何提前解盲,以及解盲之前為何就有資料可以送到ASCO?對此,浩鼎董事長張念慈聞言罕見動怒,浩鼎表示,張念慈將親上火線澄清。沈富雄昨天在電視談話節目上大肆抨擊,説浩鼎對提前解盲一事,始終未解釋清楚;另外指出,浩鼎二月初送出研究摘要給美國ASCO期刊,但221日才說沒解盲,沒解盲怎麼敢寫報告?沈富雄請張念慈在今天早上九點前給他答案,否則就舉行記者會公開質疑。沈富雄昨日在電視節目上提及浩鼎案,他指浩鼎案有幾個疑點:為何要提早解盲?「那解盲結果差別為何消失,到底原先差在哪裡,這要給國人一個交代」。沈富雄提出第二個質疑是:為何2月初先送摘要到美國期刊ASCO發表,但221日才宣告解盲失敗,為何沒解盲前就可以寫文章?
