I-Stellar Biotech Limited yinkampani ehamba phambili embonini yemithi yokunakekelwa kwezempilo, enezindawo ezimbili ezinkulu eSingapore naseHong Kong. Le nkampani izibophezele kakhulu ekuthuthukiseni impilo yomhlaba wonke ngobuchwepheshe bayo emithini nasemishini yezokwelapha. Izigxile ekuthuthukisweni kwemithi, ukuthobela imithetho, nokuthengisa, i-Stellar Biotech ihlose ukuletha izixazululo ezintsha zokunakekelwa kwezempilo ezithuthukisa imiphumela yeziguli emhlabeni wonke. Amakhono ayo aqinile avumela izinkampani zemithi, izikhungo zezokwelapha, nabasabalalisi ukuthi bathole kalula imikhiqizo esezingeni eliphezulu, eqinisekiswe yi-GMP, enikeza izixazululo ezisheshayo nezihambisana nemithetho zokuhlinzekwa. Lokhu kuzinikela kwenza i-Stellar Biotech ibe uzakwethu omethembayo emkhakheni wezokunakekelwa kwezempilo.

I-TPIAO, eyaziwa ngokwesayensi ngokuthi i-Recombinant Human Thrombopoietin (rhTPO), iyimithi entsha eyenzelwe iziguli ezihlupheka nge-thrombocytopenia — isimo esibonakala ngokuba namazinga aphansi kakhulu ama-platelet egazini. Ama-platelet abalulekile ekujiyeni kwegazi nasekuvimbela ukopha ngokweqile. I-TPIAO idlala indima ebalulekile ekukhuthazeni ukukhiqizwa kwama-platelet, okwenza kube yimpumelelo enkulu ekwelapheni izifo zokushoda kwama-platelet. Ngobuchwepheshe bayo obusezingeni eliphezulu bokuhlanganisa, i-TPIAO ibekwe njengesixazululo esibalulekile semithi emkhakheni wezempilo, ihambisana nomsebenzi we-Stellar Biotech wokuhlinzeka ngemithi esebenza kahle, ephephile, futhi etholakalayo.

I-TPIAO ikhombisa ngokukhethekile ukwelashwa kwezimo ezimbili ezinkulu zezokwelapha ezibandakanya ukushoda kwamaplatelet. Okokuqala, ibhekana ne-chemotherapy-induced thrombocytopenia, inkinga ejwayelekile ezigulini zomdlavuza eziphathwa nge-chemotherapy ebanga amazinga aphansi kakhulu ama-platelet (ngaphansi kuka-50×10⁹/L). Okwesibili, isekela iziguli ezine-immune thrombocytopenic purpura (ITP), ikakhulukazi lezo ezinezinga lamaplatelet elingaphansi kuka-20×10⁹/L futhi ezingaphendulanga kahle ekwelashweni nge-corticosteroid noma i-splenectomy. Umkhiqizo uhloselwe iziguli ezisengozini enkulu yokopha ngenxa yamaplatelet aphansi futhi awuhloselwe ukusetshenziswa kwe-prophylactic okuhloswe kuphela ukuze kuthuthukiswe amazinga ama-platelet. Lezi zinkomba zigcizelela indawo ebalulekile ye-TPIAO yokwelapha ku-hematology kanye ne-oncology.

I-Recombinant Human Thrombopoietin (rhTPO) ifana ne-hormone yemvelo i-thrombopoietin, elawula ukukhiqizwa kwamaplatelet emnkantshubomvu. I-TPIAO ibopha kuma-receptor athile kuma-precursor e-megakaryocyte, iqhubekisele phambili ukwanda kwawo nokuhlukana kwawo abe ama-platelet avuthiwe. Lo mshikashika we-biological uthuthukisa izinombolo zamaplatelet ngempumelelo, kunciphisa ubungozi bezinkinga zokopha ezigulini ezithintekayo. Imvelo ye-recombinant ye-TPIAO iqinisekisa umphumela wokwelapha oqhubekayo futhi onamandla, okwenza kube inketho yokwelapha ephumelelayo ye-thrombocytopenia. Ukuqonda lo mshikashika kunikeza ukuqonda ngokuthi izindlela zokwelapha ezintsha zemithi zingathuthukisa kanjani imiphumela yezokwelapha.

Izifundo zezokwelapha zibonise ukuthi i-TPIAO inikeza izinzuzo ezinkulu ekwandiseni inani lamaplatelet ezigulini ezine-thrombocytopenia ebangelwa yi-chemotherapy kanye ne-ITP. Ukusetshenziswa kwayo kuhlotshaniswa nokuncipha kwezikhathi zokopha, ukuncipha kwesidingo sokudluliselwa kwamaplatelet, kanye nokuthuthukiswa kokubekezelelana nezindlela zokwelapha nge-chemotherapy. Iphrofayela yokuphepha ye-TPIAO isungulwe kahle, nemiphumela emibi ngokuvamile ilula futhi ingalawuleka. Lokhu kufaka phakathi izimpawu zesikhashana zokubeka umjovo kanye nemiphumela embalwa yesistimu. Isilinganiso esihle sezibonelelo-ubungozi senza i-TPIAO ibe inketho yokwelapha efanelekile futhi ephumelelayo, iphakanyise amazinga okunakekelwa ekuphathweni kokushoda kwamaplatelet.

Iziguli ezifanelekela ukwelashwa nge-TPIAO zihlanganisa lezo ezinezinga lamaplatelet elingaphansi kuka-50×10⁹/L ngenxa ye-chemotherapy kanye neziguli ezine-ITP engaphenduli emithini ezinezinga lamaplatelet elingaphansi kuka-20×10⁹/L. Iziqondiso zokwelashwa zincoma ukunikezwa ngaphansi kokuqondiswa kwezokwelapha ngokugadwa kwezinga lamaplatelet kanye nengozi yokopha. I-TPIAO akufanele isetshenziswe ezigulini ezizama ukwenza izinga lamaplatelet libe njengokujwayelekile ngezizathu ezingahlobene nengozi yokopha ngokomtholampilo. I-Stellar Biotech, ngemisebenzi yayo ephelele yezemithi, iqinisekisa ukuthi abahlinzeki bezempilo bayathola iziqondiso ezinemininingwane kanye nokwesekwa ukuze kusetshenziswe i-TPIAO ngokuphepha nangempumelelo.

Ukwethulwa kwe-TPIAO kubonisa isinyathelo esiguqulayo ekwelashweni kwe-thrombocytopenia embonini yemithi yokunakekelwa kwezempilo. I-Stellar Biotech Limited iyaqhubeka nokuphakamisa izixazululo zezempilo ezintsha futhi ezihambisana nemithetho, iqhubekisela phambili ukwelashwa okuthuthukisa ikhwalithi yokuphila kwez pacienti kanye nemiphumela yezokwelapha. Ngemikhiqizo efana ne-TPIAO, ikusasa lithembisa ukuphathwa okuthuthukisiwe kwezimo zokushoda kwamaplatelet, kusekelwa ubuhlakani besayensi kanye nobudlelwano obuqinile bezempilo. Ngeminye imininingwane ngephothifoliyo yemithi kanye nezinsizakalo ze-Stellar Biotech, vakashela iwebhusayithi yabo.Imikhiqizo ikhasi, noma ufunde ngomsebenzi wenkampani wezempilo emhlabeni wonke ku-Ikhaya ikhasi.
