Nirmatrelvir
Nirmatrelvir waa horjooge ka mid ah SARS-CoV-2 protease ugu weyn (Mpro), oo sidoo kale loo yaqaan 3C-sida protease (3CLpro) ama nsp5 protease. Xannibaadda SARS-CoV-2 Mpro waxay ka dhigaysaa mid aan awood u lahayn socodsiinta horudhacayaasha polyprotein-ka, ka hortagga taranka fayraska.
Nirmatrelvir waxay joojisay dhaqdhaqaaqa dib-u-habaynta SARS-CoV-2 Mpro ee baadhista bayooloji ee xaddiyada lagu gaari karo vivo. Nirmatrelvir waxaa la ogaaday inuu si toos ah ugu xidho SARS-CoV-2 Mpro goobta firfircoon ee raajada crystallography.
Ritonavir waa HIV-1 protease inhibitor laakiin ma aha mid ka hortagaya SARS-CoV-2 Mpro. Ritonavir waxay joojisaa dheef-shiid kiimikaad dhexdhexaad ah ee CYP3A ee nirmatrelvir, taasoo keentay in la kordhiyo uruurinta plasma ee nirmatrelvir.
Daawadan ayaa lagula talinayaa. Waxaa la siiyay oggolaanshaha isticmaalka deg-degga ah ee FDA ee daawaynta cudurka coronavirus-ka-dhex-dhexaadka ah (COVID-19) ee dadka waaweyn iyo bukaannada carruurta (12 sano jir iyo ka weyn oo miisaankoodu yahay ugu yaraan 40 kiiloogaraam ama qiyaastii 88 rodol) oo leh Natiijooyinka togan ee baaritaanka tooska ah ee SARS-CoV-2, iyo kuwa halis sare ugu jira u gudbida COVID-19 daran, oo ay ku jiraan isbitaal dhigga ama dhimashada. Nirmatrelvir/ritonavir waa in la bilaabo sida ugu dhakhsaha badan ee suurtogalka ah ka dib marka la ogaado COVID-19 iyo shan maalmood gudahooda ee calaamaduhu.
Talooyinku waxay ku saleysan yihiin EPIC-HR, tijaabada kantaroolka kiliinikada ee la kala soocay ee Wajiga2/3 qiimaynta waxtarka nirmaltrelivir/ritonavir vs. placebo ee dhimista isbitaal dhigista iyo dhimashada ilaa maalinta 28. Isticmaalka nirmaltrelivir/ritonavir 5 maalmood gudahooda marka calaamaduhu bilaabmaan Shakhsiyaadka halista ugu jira inay u gudbaan cudur daran waxay hoos u dhigeen khatarta cisbitaalka ama dhimashada 28 maalmood 88%.
