集採PD-1降價不及預期?恆瑞、信達放量漲逾7%
格隆匯 12-15 17:35

截至12月15日收盤,醫藥生物板塊整體上漲,成交金額796億元,較上日增加146億元。個股層面,華北製藥、豐原藥業封板,澤璟製藥-U、信立泰、恆瑞醫藥放量漲逾7%。

值得注意的是,恆瑞醫藥時隔4個月重回5000億市值,報收於97.02元/股,漲幅7.67%。

對於恆瑞醫藥放量大漲的原因,一方面,其1類抗腫瘤創新藥氟唑帕利膠囊於14日獲批上市;另一方面,2020年國家醫保目錄談判正在進行時,從首日談判成果來看,此輪價格降幅相較往年“温和”,PD-1降價或不及預期,進而導致其股價大漲。具體來看:

12月14日,恆瑞自主研發的PARP抑制劑氟唑帕利膠囊(商品名:艾瑞頤)獲NMPA批准上市,這是首個國產PARP抑制劑藥物。

簡單來説,PARP抑制劑是一種抗癌藥物,尤其在卵巢癌、乳腺癌、前列腺癌等治療領域具有療效。截至目前,全球共批准4款PARP抑制劑,分別是阿斯利康的奧拉帕利、Clovis公司的蘆卡帕利、再鼎醫藥的尼拉帕利和輝瑞的他唑拉帕利,其中尼拉帕利和奧拉帕利已在國內獲批。

2019年,上述四款PARP抑制劑全球銷售額約為13.57億美元,美國銷售額約為6.74億美元。其中奧拉帕利全球已獲批適應症最多,包括前列腺癌、卵巢癌、胰腺癌、乳腺癌等6種,其銷售額在2019 年已達到16.42億美元,同比增長94.8%。

此次,恆瑞醫藥的氟唑帕利獲批上市,成為國內第三個獲批上市的PARP抑制劑,亦是國內首個自主研發的PARP抑制劑。中信建投預計,氟唑帕利國內銷售峯值將達50億元。

與此同時,2020年國家醫保目錄談判正如茶如火進行着……由於今年由遴選制改為申報制,且條件大大放寬,這也意味着將有超百種藥品面臨“靈魂砍價”。

其中最具看點的仍然是PD-1單抗。

2019年,信達生物的信迪利單抗(商品名:達伯舒)以降價64%,成為四家參與談判的藥品中唯一成功進入醫保目錄的PD-1產品,其餘三家參與談判公司分別是外資藥企默沙東、BMS和國內君實生物。

進入醫保前,PD-1在國內定價為每100毫克7838元,醫保支付價為2843元,降低63.7%。換而言之,醫保報銷後個人負擔的年費用只有2.9萬元。這與PD-1產品剛進入中國時,每年高達二三十萬元的花費相比,僅僅是個零頭。

儘管納入醫保伴隨着價格下降,但同時帶來銷售量的顯著提升。根據信達生物財報,

2019年,年度的總收入為10.48億元,其中PD-1信迪利單抗在2019年3月上市銷售後賣了10.16億元,毛利率高達88.1%。

而今年,PD-1的競爭賽道變得更加擁擠,除了信達的“達伯舒”外,還有7款上市PD-(L)1參與競爭,包括默沙東的帕博利珠單抗、百時美施貴寶的納武利尤單抗、恆瑞醫藥的卡瑞利珠單抗、百濟神州的替雷珠單抗等。

由於參與競爭較多,行業人士此前對於PD-1在本次談判的預計相對悲觀。恆瑞醫藥亦被市場認為釋放出降價信號,此前10月對外放風將卡瑞利珠單抗價格“跳樓式”降到3萬元/年。

不過,從醫保談判首日成果來看,似乎與業內普遍預期的“靈魂砍價”稍有差距。14日,參與中成藥競標的一位中成藥企業代表表示,公司產品在壓價1/3後中標。另有一家藥企則稱其降價幅度達到了40%。與2019年價格平均下降60%相比,稍顯“温和”。

據悉,PD-1產品或在醫保談判第三天進行(即12月16日),但從二級市場反應來看,市場已提前預測PD-1降價可能不及預期。

截至收盤,信達生物漲幅7.92%,報收於60.650港元/股。
