I-Pralsetinib - Ukusetyenziswa, Idosi, Iziphumo ebezingalindelekanga kunye nokunye

I-Pralsetinib liyeza lonyango elijoliswe kulo elisetyenziswa kakhulu kunyango lweentlobo ezithile zomhlaza, ingakumbi umhlaza wemiphunga ongengoweeseli ezincinci (i-NSCLC) onemiguquko ethile yemfuza. Ihlelwa njengesithinteli esikhethiweyo se-RET (ehlelwe ngokutsha ngexesha lokudluliselwa kwe-transfection) kinase, edlala indima ebalulekileyo kwiindlela zokubonisa iiseli ezikhuthaza ukukhula kweeseli zomhlaza. Ngokuthintela le kinase, i-Pralsetinib inceda ekunciphiseni okanye ekumiseni ukukhula kweeseli zomhlaza, nto leyo eyenza ukuba ibe lukhetho olubalulekileyo kwizigulane ezine-RET fusion positive tumors.

Ukusetyenziswa kwePralsetinib

I-Pralsetinib ivunyiwe ukunyanga izigulana zabantu abadala abanomhlaza wemiphunga ongengoweeseli ezincinci (i-NSCLC) onokuthi ube ne-RET gene fusions. Ikwaboniswa nakwizigulana ezinomhlaza we-thyroid we-RET-mutant medullary medullary (MTC) oqhubele phambili okanye oqhubekekayo. Ezi mpawu zibonisa indima ye-Pralsetinib ekujoliseni utshintsho oluthile lwemfuza kwiithumba, okuvumela indlela yonyango lomhlaza eyenzelwe wena ngakumbi.

Isebenza njani iPralsetinib

I-Pralsetinib isebenza ngokujolisa ngokukodwa kwaye ithintele umsebenzi we-RET kinase, ebandakanyeka kwiindlela zokubonisa ezikhuthaza ukwahlukana kweeseli kunye nokusinda. Kwimihlaza ene-RET fusions, le kinase idla ngokusebenza kakhulu, nto leyo ekhokelela ekukhuleni okungalawulwayo kweeseli zomhlaza. Ngokuvimba i-RET, i-Pralsetinib iyayiphazamisa le miqondiso, inciphisa okanye iyeke ukwanda kweeseli zomhlaza. Le ndlela ivumela uhlaselo olujolise ngakumbi kwiiseli zomhlaza ngelixa igcina iiseli eziqhelekileyo, nto leyo enokubangela iziphumo ebezingalindelekanga ezimbalwa xa kuthelekiswa ne-chemotherapy yendabuko.

Isisombululo kunye noLawulo

Umlinganiselo oqhelekileyo wePralsetinib kubantu abadala udla ngokuba yi-400 mg ethathwa ngomlomo kanye ngemini. Kubalulekile ukuthatha amayeza ngexesha elifanayo yonke imihla ukuze kugcinwe amanqanaba afanayo emzimbeni. I-Pralsetinib ingasetyenziswa kunye nokutya okanye ngaphandle kokutya, kodwa kuyacetyiswa ukuba ungayithathi kunye nokutya okunamafutha amaninzi, njengoko oku kunokuchaphazela ukufunxwa. Kwizigulane zabantwana, umthamo unokwahluka ngokuxhomekeke kubunzima kwaye kufuneka umiselwe ngumboneleli wezempilo. I-Pralsetinib kufuneka ithathwe esiswini esingenanto - ukutya okungekho nto ubuncinane iiyure ezi-2 ngaphambi kunye neyure e-1 emva kokuthatha umthamo - ukuqinisekisa ukufunxwa okufanelekileyo.

Iziphumo ebezingalindelekanga zePralsetinib

Njengazo zonke iziyobisi, iPralsetinib inokubangela iziphumo ebezingalindelekanga. Iziphumo ebezingalindelekanga eziqhelekileyo ziquka:

• Ukukhathala
• I sizathu
• Uhudo
• Ukutyunjwa
• Ukwanda kwee-enzymes zesibindi
• Uxinzelelo lwegazi (uxinzelelo lwegazi)

Iziphumo ezibi kakhulu zinokubandakanya:

• Isifo se-Interstitial lung (ukudumba kwemiphunga)
• Iingxaki zesibindi
• Ukwaliwa kakhulu
• Isingqi sentliziyo siyatshintsha

Izigulana kufuneka zixele naziphi na iimpawu ezingaqhelekanga kumboneleli wabo wezempilo ngokukhawuleza.

Ukusebenzisana kweziyobisi

I-Pralsetinib inokusebenzisana namayeza amaninzi, nto leyo enokuchaphazela indlela esebenza ngayo okanye yonyuse umngcipheko weziphumo ebezingalindelekanga. Unxibelelwano olukhulu lwamayeza luquka:

• Ii-CYP3A4 inhibitors ezinamandla (umz., ketoconazole, ritonavir)
• Izikhuthazi ezinamandla ze-CYP3A4 (umz., i-rifampin, i-St. John's Wort)
• Amanye amayeza achaphazela i-enzyme yesibindi

Ngenxa yokuba iPralsetinib iguqulwa yi-enzyme yesibindi i-CYP3A4, kufuneka kuqatshelwe nge-CYP3A4 inhibitors ezinamandla (ezifana ne-ketoconazole, i-ritonavir) kunye ne-inducers (ezifana ne-rifampin, i-St. John's Wort). Ezi zinokufuna ukulungiswa kwedosi okanye ukuphepha ukusetyenziswa ngaxeshanye. Kubalulekile ukuba izigulana zazise ababoneleli bezempilo bazo malunga nawo onke amayeza, izongezo, kunye neemveliso zemifuno abazisebenzisayo ukuze baphephe ukusebenzisana okunokwenzeka.

Iingenelo zePralsetinib

Eyona nzuzo iphambili yePralsetinib kukuba ijolise ekulweni neethumba ezine-RET, nto leyo enokukhokelela kwiziphumo zonyango eziphucukileyo kwizigulana ezineprofayili ethile yemfuza. Izifundo zeklinikhi, kuquka uvavanyo lwe-ARROW, zibonise ukuba iPralsetinib ikhokelela ekuncipheni okukhulu kwethumba kwaye inceda ukugcina esi sifo silawulwa ixesha elide kwizigulana ezine-RET fusion-positive non-small cell lung cancer (NSCLC) kunye ne-RET-mutant medullary thyroid cancer (MTC). Ukongeza, ukusetyenziswa kwayo ngomlomo kunika lula xa kuthelekiswa nonyango olufakwa kwimithambo yegazi, nto leyo ephucula ukuthobela kwezigulane.

Izimo zokungahambelani nePralsetinib

I-Pralsetinib ayivumelekanga kwezinye iindawo, kuquka:

• Izigulane ezinolwazi lokungaziva kakuhle ngePralsetinib okanye nakweyiphi na inxalenye yayo.
• Abasetyhini abakhulelweyo okanye abancancisayo, njengoko inokulimaza umntwana okanye usana.
• Izigulane ezinesifo sesibindi esinzima zinokwandisa umngcipheko weziphumo ebezingalindelekanga.

Ukusetyenziswa kokuthintela ukukhulelwa okusebenzayo kuyimfuneko ngexesha lonyango lwePralsetinib kwaye ubuncinane iiveki ezi-2 emva kwedosi yokugqibela, njengoko iPralsetinib inokubangela ingozi kusana olungekazalwa. Kubalulekile ukuba izigulana zixoxe ngembali yazo yezonyango nomboneleli wezempilo ngaphambi kokuba ziqale unyango.

Izilumkiso kunye nezilumkiso

Ngaphambi kokuba uqale iPralsetinib, izigulane kufuneka ziphononongwe ngokucokisekileyo kuquka uvavanyo lokusebenza kwesibindi, uvavanyo lwempilo yemiphunga, kunye nokulinganiswa koxinzelelo lwegazi, kuba eli yeza linokubangela ubuthi besibindi, ukudumba kwemiphunga, kunye noxinzelelo lwegazi. Ngexesha lonyango, ukujonga rhoqo uxinzelelo lwegazi, ii-enzymes zesibindi (ALT kunye ne-AST), kunye neempawu zemiphunga kubalulekile ukuze kufunyanwe iziphumo ebezingalindelekanga kwangethuba kwaye zilawulwe ngokufanelekileyo.

Izigulane kufuneka zicetyiswe ukuba zibike ngokukhawuleza naziphi na iimpawu ezintsha okanye eziya ziba mandundu, ingakumbi iingxaki zokuphefumla ezifana nokukhohlela okanye ukuphefumla kancinci, iimpawu zokungasebenzi kakuhle kwesibindi ezifana ne-jaundice okanye ukudinwa okungaqhelekanga, okanye uxinzelelo lwegazi oluphezulu. Ukufunyanwa kwangoko kuvumela ababoneleli bezempilo ukuba balungise unyango njengoko kufuneka ukuqinisekisa ukhuseleko.
