En studie som evaluerer kombinasjonen av Encorafenib og Cetuximab versus Irinotecan/Cetuximab eller infusjonsbasert 5-fluorouracil (5-FU)/Folinsyre (FA)/Irinotecan (FOLFIRI)/Cetuximab hos kinesiske pasienter med BRAF V600E mutant kreftmetastaser. (NAUTICALCRC)

8. april 2026 oppdatert av: Pierre Fabre Medicament

En multisenter, randomisert, åpen, 2-arms, fase II-studie med en sikkerhetsinnledningsfase som evaluerer kombinasjonen av encorafenib og cetuximab versus irinotecan/cetuximab eller infusjonsbasert 5-fluorouracil (5-FU)/folinsyre (FA) /Irinotecan (FOLFIRI)/Cetuximab hos kinesiske pasienter med BRAF V600E mutant metastatisk kolorektal kreft.

Encorafenib utvikles for tiden (med eller uten binimetinib), i kombinasjon med cetuximab, for behandling av voksne pasienter med B-RAF proto-onkogen, serin/treoninkinase V600E mutant (BRAF V600E) metastatisk kolorektal kreft (mCRC), som har mottatt systemisk behandling tidligere.

Completions of questionnaire are summarized per treatment group and study visits. Number of participants analyzed correspond to the actual number of participants who completed the questionnaire at the corresponding visit.
