賓夕法尼亞州埃克斯頓,2025年6月2日(GLOBE NEWSWIRE)—— 在UCB的Bimzelx(bimekizumab)在銀屑病關節炎(PsA)和軸性脊椎炎(axSpA)雙重上市六個多月後,根據Spherix Global Insights的**_Launch Dynamix™_**服務,新發現顯示Bimzelx展現了顯著的潛力,儘管開處方醫生的採用動力受到接入障礙和保險公司施加的限制影響。

在PsA(n=76)和axSpA(n=73)的醫生中,對Bimzelx的臨床熱情高漲,尤其是其獨特的IL-17A和IL-17F雙重抑制作用被認為是與現有IL-17藥物的區別。在PsA中,風濕病學家對該藥物在皮膚和關節方面的表現充滿信心,並認為它在治療上優於諾華的Cosentyx和禮來的Taltz。在axSpA中,尤其是對於更嚴重或難治的患者,Bimzelx越來越被視為首選IL-17藥物,部分醫生已經將其定位在預期療效和益處的範疇上超越了已建立的選擇。

儘管臨床資料良好,Bimzelx的採用卻受到持續挑戰的報銷環境的制約。在PsA中,幾乎所有的處方都需要事先授權,步驟治療要求和保險公司對傳統藥物的偏好仍然阻礙了早期使用。這些接入挑戰在AS和nr-axSpA中也得到了反映,醫生提到不僅是高額的自付費用和醫療保險的限制,還有各計劃中普遍缺乏的藥物名單納入。雖然一些風濕病學家提到在早期使用中取得了成功,但許多人描述了經常的拒絕和延遲,這迫使他們不得不選擇更易獲得的藥物,儘管他們對Bimzelx的臨床偏好。正如一位風濕病學家總結道:“我喜歡Bimzelx。現在我面臨的主要困難是,它經常被保險公司拒絕。因此,商業保險的覆蓋率,似乎總是困擾UCB產品的,真的很差。我希望這會有所改善。”

為了應對這些接入障礙,一些醫生開始使用樣品和過渡計劃。然而,在PsA中,僅有13%的患者在開始使用Bimzelx時是通過樣品或免費藥物開始的,axSpA中也觀察到了類似的模式。雖然樣品和過渡計劃為啟動Bimzelx提供了關鍵的途徑,但醫生的情緒支持這些措施通常是用來繞過接入障礙,對於保險覆蓋的一致轉換和這種方法的可持續性仍然存在不確定性。

雖然接入障礙是一個共同的主題,並且在許多最近推出的免疫學生物製劑中也很常見,但Bimzelx在PsA和axSpA中的採用和認知卻出現了顯著差異。在PsA中,三分之二的風濕病學家已經開過Bimzelx,通常是針對經歷多次先進療法失敗的重症或急性患者。許多人表達了希望將這種療法提前到治療算法中的興趣,但再次受到保險公司要求的限制。相比之下,axSpA中的採用仍在上升,尤其是在nr-axSpA中,迄今為止只有少數風濕病學家使用過該產品。儘管採用速度較慢,但在有開處方經驗的醫生中,滿意度仍然很高,許多醫生預計隨著覆蓋改善將擴大使用。

除了試驗和使用的增長外,UCB的推廣工作也開始產生共鳴。大多數風濕病學家報告說已與Bimzelx的銷售代表接觸,並普遍讚揚他們的專業性和溝通關鍵療效及安全性差異的能力。然而,PsA和axSpA中仍有一部分醫生尚未接觸,對於支持服務(例如Bimzelx Navigate計劃)的認識有限,這表明仍需加強工作以充分激活開處方基礎。那些參與Navigate計劃的人報告了積極的經驗,稱讚及時的支持和易用性,但這些反饋仍然有限。

隨著推出進展,關鍵問題是UCB能否將強烈的臨床認知轉化為早期護理中的實際使用。儘管Bimzelx在療效方面的定位良好,但其長期成功將取決於克服保險公司的抵制和改善患者的接入。

Spherix Global Insights將繼續通過其**_Launch Dynamix™_**服務跟踪Bimzelx在PsA、AS和nr-AxSpA的美國上市軌跡,直至商業可用的前十八個月。
