About this trial
Many patients with CLL have a weakened immune system due to their disease. It increases their risk of developing serious, treatment-requiring infections such as blood poisoning or pneumonia, which in the worst case may end with fatal outcomes.
Serious infections due to CLL are responsible for one third of all deaths among CLL patients. PreVent-ACaLL study will investigate whether a combination of two known types of cancer drugs can reduce the risk of infection and thus mortality when given preventively to newly diagnosed CLL patients.
A newly developed register-based computer model can predict which patients are at high risk in order to develop infections as a result of their CLL. A preventive treatment might be initiated before patients need chemotherapy. In this way, the cancer disease might be "reset" so that the immune system, which is inhibited by CLL, is restored and the risk of fatal infections is minimized.
