Ggwe oba omuntu ali ku lusegere lwo bw’azuulibwa nti alina kookolo w’amabeere, oyinza okuba ng’owulidde abasawo nga bakozesa ebigambo nga ‘ HER2-Positive ’ oba ‘HER2-low’. Mu butuufu gano ge mannya agakozesebwa okunnyonnyola ebika by’obutoffaali bwa kookolo. Kati waliwo eddagala eppya, ery’omulembe erijjanjaba kookolo ow’ekika kino. Eddagala erimu ery’enjawulo eryo ye Enhertu. Leero, tugenda kwogera ku nsonga eno mu ngeri ennyangu era ennyangu okutegeera.
Enhertu ddagala lya ngeri ki? Kikola kitya?
Mu ngeri ennyangu, Enhertu bujjanjabi obugendereddwamu . Okubeera omutuufu, kika kya ddagala eriyitibwa `Antibody-Drug Conjugate (ADC).` Wadde erinnya lino liyinza okuwulikika nga lizibu katono, engeri gye likolamu yeewuunyisa nnyo.
Eddagala lino lilowoozeeko nga mizayiro entegefu. Kikolebwa ebitundu bisatu:
1. Ekitundu ekizuula ekigendererwa (Antibody): Ekitundu kino kisanga puloteyina ey’enjawulo eyitibwa `HER2` ku ngulu w’obutoffaali bwa kookolo ne yeekwatako. Omulimu gw’ekitundu kino kwe kulondawo okuzuula n’okukuuma obutoffaali bwa kookolo bwokka, awatali kutuusa bulabe ku butoffaali bulamu.
2. Payload: Lino lye ddagala eritta obutoffaali bwa kookolo. Okubeera omutuufu, kino kika kya ddagala lya maanyi nnyo.
3. Ekitundu ekigatta bino ebibiri (Linker): Ebitundu ebibiri ebyogeddwako waggulu biyungibwa wamu ekiyungo kino.
Kale, bw’owa eddagala lino, ekitundu kyalyo ekiziyiza obuwuka kigenda butereevu mu butoffaali bwa kookolo obulina puloteyina ya `HER2`. Oluvannyuma, eddagala lino liyingizibwa mu katoffaali. Oluvannyuma lw’okuyingira munda mu katoffaali, ekitundu kya chemo kifuluma ne kisaanyaawo akatoffaali ka kookolo. Obutoffaali bwa kookolo bwe bufa, obutoffaali bwa kookolo bukendeera ne bulekera awo okukula.
Ekirungi ekisinga obunene ekiri mu nkola eno kiri nti eddagala lino litunuulira butereevu obutoffaali bwa kookolo bwokka, n’olwekyo okwonooneka kw’obutoffaali obulamu kukendeera nnyo.
Enhertu eweebwa etya?
Enhertu ddagala eriweebwa mu misuwa. Kino kitegeeza nti kiweebwa mu mubiri nga saline solution (IV infusion). Obujjanjabi buno bujja kukuweebwa omukugu mu by’obulamu mu ddwaaliro, mu ddwaaliro, oba ekifo eky’enjawulo eky’obujjanjabi.
- Ebbanga: Obujjanjabi buno butera okuweebwa omulundi gumu buli wiiki 3 .
- Omuwendo gw’eddagala: Omuwendo gw’eddagala gwe weetaaga gusalibwawo okusinziira ku buzito bw’omubiri gwo. Omusawo ajja kugibalirira ddala era ajja kugiwandiika.
- Ebiseera ebigere:Singa kookolo wo akola bulungi eddagala lino, omusawo ajja kukuwa amagezi okugenda mu maaso n’obujjanjabi buno okumala ebbanga nga bwe kisoboka. Kyokka bw’ofuna ebizibu ebimu, kiyinza okwetaagisa okukyusa ddoozi y’eddagala, okuyimiriza obujjanjabi okumala akaseera oba n’okulikomya ddala. Bino byonna omusawo ajja kukuteesaako naawe era akusalewo.
Ddala eddagala lya Enhertu likola litya?
Okugezesebwa kubiri mu malwaliro okunoonyereza ku bulungibwansi bw’eddagala lya Enhertu kuvuddemu ebirungi nnyo.
1. Okugeraageranya Enhertu ne Kadcyla (okugezesebwa kwa DETINY-Breast03) .
Mu kugezesebwa kuno, Enhertu yageraageranyizibwa ku Kadcyla (ado-trastuzumab emtansine), eddagala eddala erigenderera ``HER2.'' Ebivuddemu biragiddwa mu kipande wansi.
| Ensonga y’okugeraageranya | Enhertu obujjanjabi | Obujjanjabi bwa Kadcyla |
|---|---|---|
| Okuwangaala okutaliimu kukulaakulana (Kino kye kiseera ekitwala ekitundu ky’abalwadde okuddamu okufuna kookolo oba obutasaasaana) | Emyezi 28.8 | Emyezi 6.8 |
| Ebitundu by’abalwadde abataasaasaanyizza bulwadde buno oluvannyuma lw’emyezi 12 | Ebitundu 75.2% | 33.9% |
| Ebitundu by’abalwadde abataasaasaanyizza bulwadde buno oluvannyuma lw’emyezi 24 | Ebitundu 53.7% | 26.4% |
2. Okugeraageranya Enhertu n’obujjanjabi bw’eddagala (DESTINY-Breast04 trial) .
Okugezesebwa kuno kwageraageranya Enhertu n’eddagala erya bulijjo.
| Ensonga y’okugeraageranya | Enhertu obujjanjabi | Obujjanjabi bwa Chemotherapy |
|---|---|---|
| Okuwangaala okutaliimu kukulaakulana | Emyezi 9.9 | Emyezi 5.1 |
| Okuwangaala okutwaliza awamu (Kino kye kiseera ekitundu ky’abalwadde abaafunye obujjanjabi we baawona) | Emyezi 23.4 | Emyezi 16.8 |
Data eno eraga nti Enhertu bujjanjabi bukola nnyo okusinga obumu ku bujjanjabi obuliwo kati .
Nlondoola ntya okuwona kwange?
Enhertu etandika okukola amangu ddala ng’ofunye ddoozi yo esooka. Omusawo ajja kukola ebigezo eby’enjawulo alabe engeri omubiri gwo gye gukwatamu eddagala.
- Sikaani: Sikaani etera okukolebwa nga wayise wiiki nga 6 ng’omaze okutandika obujjanjabi okukebera kookolo bw’agenda mu maaso. Kino kiyinza okukolebwa nga bukyali oba oluvannyuma.
- Okukebera omusaayi: Okukebera omusaayi buli kiseera okukebera obutoffaali bwo obweru, obusimu obuyitibwa neutrophil, ne platelet. Kino kijja kukuyamba okuzuula oba osobola okugenda mu maaso n’okumira eddagala lino awatali bulabe. Bw’ofuna ebizibu, gamba ng’okusesema, oyinza n’okukeberebwa ebirala eby’enjawulo okubinoonya.
Ebizibu ebivaamu n’engeri y’okubiddukanyaamu?
Ebizibu ebivaamu bitera okubaawo mu bujjanjabi bwa kookolo. Kino kituufu ne ku Enhertu. Ekisinga obukulu kwe kubuulira omusawo wo ku bizibu byonna by’ofuna. Ajja kusalawo oba siriyaasi era akubuulire eky’okubikolako.
Okuziyiza ebizibu ebitera okubaawo ng’okusesema n’okuziyira, omusawo ayinza okukuwa eddagala eddala ly’olina okumira nga tannakuwa ddagala. Kikulu nnyo okugoberera ddala ebiragiro ebyo.
Ng’oggyeeko ekyo, osobola n’okukola ebintu ebyangu nga bino okuyamba okufuga okuziyira, okusiiyibwa n’ekiddukano:
- Lya emmere etali nnungi nga temuli mafuta matono ne chili.
- Mu kifo ky’okulya emmere ennene ssatu, okulya emmere entonotono eziwerako olunaku.
Okusinziira ku buzibu bw’ebizibu ebimu, omusawo ayinza okusalawo okukendeeza ku ddoozi y’eddagala lyo, okuyimiriza obujjanjabi okumala akaseera oba okulikomya ddala. Tokyeraliikirira. Byonna bya bukuumi bwo.
Waliwo okulabula okw’enjawulo kw’olina okumanya?
Yee. Enhertu erina okulabula kwa black box okw'amaanyi ennyo . Kuno kwe kulabula okusinga obunene okufulumiziddwa ekitongole kya FDA (US Food and Drug Administration).
1. Obulabe eri omwana ali mu lubuto: Olina okwewala ddala okufuna olubuto ng’omira eddagala lino. Kino kiyinza okukosa ennyo omwana ali mu lubuto. Bw’oba ggwe oba munno muteekateeka okufuna olubuto, kakasa nti otegeeza omusawo wo . Omusawo ajja kukuwa amagezi ku nkola entuufu ey’okuziyiza okuzaala gy’olina okukozesa ng’ojjanjabibwa.
2. Okwonooneka kw’amawuggwe: Eddagala lino liyinza okuleeta embeera y’amawuggwe ey’amaanyi eyitibwa `Interstitial Lung Disease (ILD).` N’olwekyo, omusawo wo ajja kukulondoola kino mu kiseera kyonna eky’obujjanjabi. Bw’ofuna obubonero ng’okusesema n’okukaluubirirwa okussa, tegeeza omusawo mu bwangu.
Olw’ensonga zino, kikulu nnyo okusigala ng’okwatagana n’omusawo buli kiseera n’okugoberera ddala ebiragiro bye.
Obubaka Obutwala Awaka
- Enhertu ddagala lya mulembe erigenderera obutoffaali bwa HER2 mu kookolo w’amabeere era litta obutoffaali bwa kookolo bwokka.
- Buno bujjanjabi obuweebwa okuyita mu musuwa (IV) buli luvannyuma lwa wiiki 3.
- Okugezesebwa mu malwaliro kulaga nti eddagala lino likola nnyo okusinga obujjanjabi obulala obukozesebwa mu kiseera kino.
- Ebizibu ng’okuziyira n’okusiiyibwa biyinza okubaawo ng’ojjanjabwa, era waliwo engeri y’okubiddukanyaamu. Tegeeza mangu omusawo wo ku buzibu bwonna.
- Okumira eddagala lino ng’oli lubuto kiyinza okuleeta obulabe obw’amaanyi ku mwana ali mu lubuto, era waliwo akabi k’ebizibu eby’amaanyi ebikosa amawuggwe. Yogerako n’omusawo wo ku nsonga eno mu lwatu.
