Participants who have received an allogeneic haematopoietic stem cell transplant within 6 months prior to the first administration of the investigational product, have received an autologous haematopoietic stem cell transplant within 100 days prior to the first administration of the investigational product, or have received CAR-T cell therapy within 3 months prior to the first administration of the investigational product. Participants with active graft versus host disease;
