Yini i-Evinacumab: Ukusetshenziswa, Umthamo, Imiphumela Eceleni Nokunye

I-Evinacumab iyimithi ekhethekile ejovwayo eyenzelwe ukwehlisa amazinga e-cholesterol aphezulu kakhulu kubantu abanesimo esingavamile sezakhi zofuzo esibizwa ngokuthi i-homozygous familial hypercholesterolemia (HoFH). Lokhu kwelashwa okunamandla kusebenza ngendlela ehlukile kunemithi ejwayelekile ye-cholesterol ngokuvimba iphrotheni ethile evimbela umzimba wakho ukuthi ungakhiphi i-cholesterol embi egazini lakho.

Uma wena noma othile omkhathalelayo etholiwe ukuthi une-HoFH, cishe uzizwa ukhungathekile ngamagama ezokwelapha nezinketho zokwelapha. Le mithi imelela ukuqanjwa okukhulu kwabantu abamazinga e-cholesterol ahlala ephakeme ngendlela eyingozi naphezu kokuzama ezinye izindlela zokwelapha.

Yini i-Evinacumab?

I-Evinacumab iyimithi ye-monoclonal antibody eqondise iphrotheni ebizwa nge-ANGPTL3 (angiopoietin-like protein 3). Le phrotheni ngokuvamile iphazamisa ikhono lomzimba wakho lokwehlisa amafutha ne-cholesterol egazini lakho.

Cabanga nge-ANGPTL3 njengebhegi elinciphisa uhlelo lomzimba wakho lokususa i-cholesterol ngokwemvelo. I-Evinacumab ikhulula leyo bhegi, ivumela umzimba wakho ukuthi usebenze futhi ususe i-cholesterol ngempumelelo enkulu. Le mithi yenzelwe ngokuqondile abantu abane-homozygous familial hypercholesterolemia, isimo esingavamile sezakhi zofuzo esithinta cishe umuntu oyedwa kwabangu-300,000 emhlabeni jikelele.
