Sonrotoclax Plus Azacitidine in Patients With MDS-IB2

Korábbi kezelés

• Prior treatment with chemotherapy, sonrotoclax, or other BCL-2 inhibitors.
• Active graft-versus-host disease (GVHD) after prior allogeneic hematopoietic stem cell transplantation or ongoing requirement for systemic immunosuppressive therapy.
• Anticipated need for continuous use of a strong CYP3A inhibitor during sonrotoclax initiation and dose ramp-up that cannot be discontinued or replaced.
• Concurrent participation in another interventional clinical study without meeting applicable discontinuation requirements.

Más betegség

• Disease already transformed to acute myeloid leukemia (AML).
• Uncontrolled active infection, including severe bacterial, fungal, or viral infection.
• Active hepatitis B, hepatitis C, human immunodeficiency virus (HIV) infection, or active tuberculosis that is not adequately controlled.
• Significant uncontrolled cardiac, hepatic, renal, or other major organ dysfunction that, in the investigator's judgment, would preclude safe study treatment.
• Uncontrolled high risk of tumor lysis syndrome (TLS) that, in the investigator's judgment, makes the participant unsuitable for sonrotoclax treatment.
• Known severe hypersensitivity to sonrotoclax, azacitidine, or any of their excipients.
• Any other condition that, in the investigator's judgment, makes the participant unsuitable for participation in the study.
