Léčebné vzorce a klinické výsledky kombinací palbociklib u HR+HER2-MBC (PRECIOUS)

9. června 2026 aktualizováno: Pfizer

Kombinace palbociklibu u pacientek s HR+/HER2- metastatickým karcinomem prsu: Neintervenční prospektivní studie o léčebných vzorcích a klinických výsledcích v Africe na Středním východě (PRECIOUS)

Cílem této neintervenční multicentrické studie je poskytnout prospektivní, observační data o pacientech zahajujících léčbu kombinací palbociklib, která by přispěla ke znalostem managementu HR+ HER2-metastatického/lokálně pokročilého karcinomu prsu (BC), jeho léčebného vzoru, klinických výsledků a kvalitu života (QoL) v běžné klinické praxi v Africe a zemích Středního východu.

Detailní popis

Pacienti s HR+/HER2- metastatickým/lokálně pokročilým BC, jejichž ošetřující lékař rozhodl o léčbě palbociklibem a kteří splňují kritéria způsobilosti, budou pozváni k účasti ve studii. Do studie mohou být zařazeni pacienti, kteří zahájí léčbu palbociklibem plus letrozol/inhibitor aromatázy nebo palbociklibem plus fulvestrant v souladu s licencovanou indikací (indikacemi), jako první nebo druhou linii léčby metastatického/lokálně pokročilého BC při zařazení.

Proměnné hodnocené v této studii budou demografie pacienta, klinické charakteristiky, komorbidní stavy a souběžná medikace, anamnéza lokálně pokročilé a metastatické BC HR+ HER2, současná léčba BC, výkonnostní stav (Eastern Cooperative Oncology Group (ECOG), klinické výsledky a QoL. Všechna hodnocení popsaná v tomto protokolu se provádějí jako součást běžné klinické praxe nebo pokynů pro standardní praxi pro populaci pacientů a specializaci poskytovatelů zdravotní péče v zemích, kde se tato neintervenční studie provádí. Všechna data shromážděná v této studii jsou určena k zachycení skutečných vzorců léčby a výsledků u pacientů s HR+/HER2- metastatickým/lokálně pokročilým BC. Pro sběr dat bude použit elektronický formulář kazuistiky (eCRF). Zkoušející budou proškoleni úvodní návštěvou na klinice ohledně protokolu, systému elektronického sběru dat (EDC) (tj. eCRF), hlavního souboru vyšetřujícího pracoviště (ISMF), dokumentace a jakýchkoli použitelných procesů studie. Jakékoli nové informace související s prováděním této neintervenční studie (NIS) budou během studie předány zdravotnickému personálu. Dálkové monitorování dat bude prováděno během doby trvání studie, aby bylo zajištěno včasné vykazování bezpečnostních dat, integrity a konzistence dat.
