盟委員會首批候選五種治療COVID-19有效藥物組合 - 低級黑小明

盟委員會首批候選五種治療COVID-19有效藥物組合

關於歐盟委員會首批候選五種有效藥物組合:
由於 COVID-19 疾病的複雜性,正在開發多種藥物,例如抗病毒藥、免疫調節劑、抗炎藥。候選藥物包括小分子、單克隆抗體以及基於細胞的療法。
正在進行的臨床試驗著眼於正在開發的產品在不同疾病階段的安全性和有效性:例如早期、輕度、中度、重度 COVID-19 疾病;在不同的患者亞群中:門診和住院患者;暴露於感染的人和長期的 COVID 患者。

五種藥物的其中四種療法是由歐洲藥品管理局持續評估的”單克隆抗體”:。
目前 EMA 正在滾動審查的四種療法是抗病毒單克隆抗體,它們針對導致 COVID-19 的 SARS-CoV-2 病毒表面的一種蛋白質(尖峰蛋白),防止病毒進入人體細胞。將它們納入滾動審查程序是基於臨床研究的有希望的初步結果。
第五種是獲得上市許可的免疫抑製劑,可以擴展到治療 COVID-19 患者。與單克隆抗體不同的是:Baricitinib(巴瑞替尼)是一種免疫抑製劑(一種降低免疫系統活性的藥物),目前被授權用於患有中度至重度類風濕性關節炎或特應性皮炎的成人。

新五種治療新冠狀病毒的藥物介紹:

1。Bamlanivimab 和 Etesevimab 組合:
是新冠病毒單克隆抗體的雙抗組合,可降低住院和死亡風險70%。 https://m.21jingji.com/article/20210210/herald/bf3e98a73c06604b18f4933bd927e5b2.html

FDA 擴大了對 AbCelera 發現的 Bamlanivimab 與 Etesevimab 聯合給藥的緊急使用授權,以包括預防 COVID-19 的暴露後預防。

包含成人和兒童患者(12歲)接觸後預防,以及老年人(體重至少40公斤)患嚴重冠狀病毒。https://www.fda.gov/drugs/drug-safety-and-availability/fda-authorizes-bamlanivimab-and-etesevimab-monoclonal-antibody-therapy-post-exposure-prophylaxis

2。Ronapreve:
該藥物為新冠狀病毒單克隆抗體組合產品。可用於預防感染、治療嚴重感染的症狀並降低入院的可能性。

3。Regdanvimab:
針對COVID-19 單克隆抗體治療藥物 regdanvimab (CT-P59) 成為韓國食品藥品安全部 (MFDS​​) 批准的首個 COVID-19 授權治療 。

4。sotrovimab:
是一種單克隆抗體療法,這種藥物已經用於治療癌症和關節炎。
來自阿聯酋 6,175 名 Covid-19 患者的數據顯示,一種新的抗病毒藥物 Sotrovimab 似乎可以 100% 成功阻止該病毒導致的死亡,並且可以 99% 有效地防止進入重症監護室。尤其令人欣慰的是,超過一半的受助者年齡在 50 歲以上,而且幾乎所有人都有伴隨的醫療問題,例如癌症、心髒病或糖尿病。https://www.thenationalnews.com/opinion/editorial/2021/07/19/new-drugs-are-beating-covid-19-not-just-vaccines/?outputType=amp&__twitter_impression=true
被感染並有住院風險的澳大利亞人現在可以使用新藥來防止症狀惡化,臨時批准使用抗體治療藥Sotrovimab。

5。Baricitinib :
一種免疫抑製劑,降低免疫系統活性的藥物。
大多數病毒都已開發出通過阻斷其信號傳導途徑來抵消干擾素作用的策略,拮抗JAK–STAT途徑的病毒編碼因子是決定毒性的關鍵因素。
巴瑞替尼Baricitinib(選擇性的JAK1和JAK2抑製劑)阻斷JAK-STAT信號會產生干擾素介導的抗病毒反應的損害,並可能對SARS-CoV-2感染的發展產生潛在的促進作用。
干擾素是感染初期防止病毒複製的最強大的先天免疫反應之一。通過乾擾素激活的JAK–STAT信號通路(主要由JAK1和JAK2介導)進行轉錄,導致許多干擾素控制的基因上調,這些基因可迅速殺死感染細胞中的病毒。 https://www.thelancet.com/journals/laninf/article/PIIS1473-3099(20)30262-0/fulltext#.XoqGLwkgkck.twitter
