Successful treatment of advanced Ebola virus infection with T-705 (favipiravir) in a small animal model



Abstract(要約)部分を抜粋

Outbreaks of Ebola hemorrhagic fever in sub-Saharan Africa are associated with case fatality rates of up to 90%. Currently, neither a vaccine nor an effective antiviral treatment is available for use in humans. Here, we evaluated the efficacy of the pyrazinecarboxamide derivative T-705 (favipiravir) against Zaire Ebola virus (EBOV) in vitro and in vivo. T-705 suppressed replication of Zaire EBOV in cell culture by 4 log units with an IC90 of 110 μM. Mice lacking the type I interferon receptor (IFNAR−/−) were used as in vivo model for Zaire EBOV-induced disease. Initiation of T-705 administration at day 6 post infection induced rapid virus clearance, reduced biochemical parameters of disease severity, and prevented a lethal outcome in 100% of the animals. The findings suggest that T-705 is a candidate for treatment of Ebola hemorrhagic fever.

サハラ以南のアフリカでエボラ出血熱の集団発生は、最大90%の致死率と関連している。現在、ワクチンも効果的な抗ウイルス治療のいずれも、ヒトでの使用のために利用可能です。ここでは、in vitroおよびin vivoでザイールエボラウイルス(EBOV)に対するピラジンカルボキサミド誘導体T-705(favipiravir)の有効性を評価した。 110μMのIC 90で4 log単位による細胞培養におけるザイールEBOVのT-705抑制複製。タイプを欠くマウスは、私は、受容体(IFNARを - / - )インターフェロンザイールEBOV誘発性疾患のためのin vivoモデルとして使用した。感染後6日目誘起迅速なウイルスクリアランスにT-705の投与開始は、疾患の重症度の生化学的パラメータを減少し、100%の動物に致死成果を防いだ。所見は、T-705はエボラ出血熱の治療のための候補であることを示唆している。


マウス実験で全ての実験体の致死を防いだのか。
人体でも同様の効果があることを期待する。切実に。

사하라 이남의 아프리카에서에볼라 출혈열의집단발생은, 최대90%의치사율로 관련하고 있다.현재,백신도효과적인 항바이러스치료의 모두, 사람으로의사용을 위해서이용 가능합니다.여기에서는,in vitro 및 in vivo로자이레에볼라 바이러스(EBOV)에 대한피라진카르보키사미드유도체T-705(favipiravir)의유효성을 평가했다. 110μM의IC 90으로4 log 단위에 의한세포 배양에 있어서의자이레EBOV의T-705억제복제.타입이부족한 마우스는,나는, 수용체(IFNAR를 - / - )인터페론자이레EBOV유발성질환을 위한in vivo 모델로서 사용했다.감염 후 6일째야기신속한바이러스클리어란스에 T-705의투여 개시는,질환의 중증도의 생화학적파라미터를감소해,100%의 동물에치사성과를 막았다.소견은,T-705는에볼라 출혈열의치료를 위한 후보인 것을 시사하고 있다.


마우스 실험으로 모든 실험체의 치사를 막았는가.
인체에서도 같은 효과가 있는 것을 기대한다.절실하게.
