Exclusion criteria

• Contraindication to any of the individual components of Glofit-Orela-Borte
• Known active infection at the time of enrollment
• Positive test results for chronic hepatitis B infection (defined as positive hepatitis B surface antigen [HBsAg] serology): Patients with occult or prior HBV infection (defined as negative HbsAg and positive hepatitis B core antibody [HbcAb]) may be included if HBV DNA is undetectable, provided that they are willing to undergo DNA testing on Day 1 of every cycle and every three months for at least 12 months after the last cycle of study treatment and appropriate antiviral therapy
• Positive test results for hepatitis C (hepatitis C virus [HCV] antibody serology testing): Patients who are positive for HCV antibody are eligible only if PCR is negative for HCV RNA
• History of other malignancies that could affect compliance with the protocol or interpretation of results
• Active autoimmune disease requiring treatment
• Primary or secondary CNS lymphoma at the time of recruitment
• Any other diseases, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of an investigational drug or that may affect the interpretation of the results or renders the patient at high risk from treatment complications
