Enrolled patients will receive combination therapy with golidocitinib (150 mg QD or 150 mg QOD) and chidamide (20 mg BIW or 25 mg BIW)； If the MTD is determined at Dose Level 1 (chidamide 20 mg BIW / golidocitinib 150 mg QD), Dose Level 0 (chidamide 20 mg BIW / golidocitinib 150 mg QOD) will be further investigated. If the MTD is not established after escalating to Dose Level 2 (chidamide 25 mg BIW / golidocitinib 150 mg QD), the recommended Phase 2 dose (RP2D) will be determined through investigator consensus.
