諾誠健華-B(09969.HK)與渤健就奧布替尼達成許可及合作協議
格隆匯7月13日丨諾誠健華-B(09969.HK)和渤健(納斯達克股票代碼:BIIB)於7月13日聯合宣佈,兩家公司就有望治療多發性硬化(MS)的口服小分子布魯頓酪氨酸激酶抑制劑(BTKi)奧布替尼達成許可及合作協定。奧布替尼是共價結合的BTK抑制劑,具有高選擇性和血腦屏障滲透性,目前正在多國針對復發緩解型多發性硬化患者開展與安慰劑對照的II期臨牀研究。
奧布替尼抑制免疫細胞(包括B細胞和髓樣細胞)信號通路中的一個關鍵激酶BTK。奧布替尼可透過血腦屏障(BBB),具有抑制中樞神經系統中的B細胞和髓樣細胞的功能的潛力,有望為所有MS亞型的疾病進展提供有益的臨牀價值。針對疾病的進展,奧布替尼有望為MS患者提供新的治療選擇以延緩疾病進展。
“考慮到MS的複雜性和慢性病特徵,我們相信奧布替尼所具有的獨特性,兼具高選擇性和中樞神經系統(CNS)滲透性,與其他BTK抑制劑相比具有潛在的臨牀優勢,”渤健研發負責人AlfredSandrock醫學博士説:“30多年來,渤健一直是MS研究領域的領導者,目前也擁有領先的MS藥物組合。我們專注於開發新一代療法,希望可以改善進展型和復發型MS患者的治療效果。”
“渤健是神經科學領域公認的領導者,我們相信本次交易有助於推進奧布替尼在多發性硬化領域的開發。”諾誠健華聯合創始人、董事長兼CEO崔霽松博士説:“考慮到奧布替尼治療MS潛在的有效性和安全性,及其血腦屏障滲透性的優秀水準,我們對奧布替尼可用於治療不同MS亞型患者的潛力感到非常激動。BTK抑制劑非常有潛力改變自身免疫性疾病治療方式,尤其是MS。”
根據協定條款,渤健將擁有奧布替尼在多發性硬化領域全球獨家權利,以及除中國(包括香港、澳門和台灣)以外區域內的某些自身免疫性疾病領域的獨家權利,諾誠健華將保留奧布替尼在腫瘤領域的全球獨家權利,以及某些自身免疫性疾病在中國(包括香港、澳門和台灣)的獨家權利。諾誠健華將獲得1.25億美元首付款,以及在達到合作約定的開發里程碑、商業里程碑以及銷售里程碑時,有資格獲得至多8.125億美元的潛在臨牀開發里程碑和商業里程碑付款。諾誠健華還將有資格因合作約定的任何產品潛在未來淨銷售額獲得在百分之十幾範圍內從低至高的分層特許權使用費。交易的完成取決於反壟斷法審查,包括美國1976年的Hart-Scott-Rodino(HSR)反壟斷改進法案,以及其他完成條件慣例。
