Inoltre, i partecipanti devono soddisfare i seguenti criteri di ammissibilità per la fase corrispondente dello studio:
un. Fase 1a: partecipanti con stato di mutazione noto e tumore che ospita una mutazione oncogenica del gene BRAF (omologo virale dell'oncogene virale del sarcoma murino v-RAF) (le mutazioni di interesse primario sono la mutazione BRAF Classe II, Classe
III mutazione o fusione BRAF). Inoltre, i partecipanti con tumori che ospitano la mutazione del gene dell'omologo dell'oncogene virale del neuroblastoma RAS (NRAS) o dell'omologo dell'oncogene del virus del sarcoma di Kirsten (KRAS) sono idonei per la Parte 1a. Per i pazienti con mutazioni KRAS, sono esclusi i tipi di tumore del cancro del colon-retto (CRC) e del cancro del pancreas. Fase 1b: i partecipanti devono avere uno stato di mutazione noto e soddisfare uno dei seguenti criteri in base al gruppo in cui sono arruolati:
I. Gruppo 1: pazienti con tipi di tumore diversi dal carcinoma del colon-retto (CRC) che presentano mutazioni BRAF V600 che sono stati trattati e sono progrediti con una precedente inibizione di BRAF e/o di proteina chinasi attivata dal mitogeno (MEK).
II. Gruppo 2: pazienti con tumori solidi avanzati che ospitano una mutazione BRAF di classe II o una mutazione di fusione BRAF III. Gruppo 3: pazienti con melanoma cutaneo che ospita una mutazione IV dell'omologo oncogeno virale RAS del neuroblastoma (NRAS).
