Background: Chronic Lymphocytic Leukaemia (CLL) is an indolent disorder, which mainly affects older adults. Since the advent of chemoimmunotherapy, great progress has been made in its treatment. However, some patients develop a more aggressive form of the disease and are included in the group of high-risk CLL patients with a dismal prognosis and a need for new therapies.
Objective: Maltotriose-modified poly(propylene imine) dendrimers were presented as potential agents in targeted therapy for CLL in the murine xenograft model.
Methods: Tumour, brain and internal organs resected from NOD scid gamma mice were subjected to gross and histopathological evaluation.
Results: Results of ex vivo tissues examination indicated that open shell glycodendrimers prevented/inhibited the spread of CLL to the brain and internal organs and its transformation into a more aggressive form.
Conclusion: The results of the study have a potentially important impact on the design of future personalized therapies as well as clinical trials.
