abstract = {Radioimmunotherapy is considered as treatment option in
recurrent and/or refractory B-cell non-Hodgkin lymphoma
(B-NHL). To overcome the dose limiting bone marrow toxicity
of IgG-based radioimmunoconjugates (RICs), we modified a
humanized diabody with 5-, 10-, or 20-kDa polyethylene
glycol (PEG) for CD22-targeted radioimmunotherapy using the
low-energy β-emitter lutetium-177 ((177)Lu). A favorable
pharmacokinetic profile was observed for the
10-kDa-PEG-diabody in nude mice being xenografted with
subcutaneous human Burkitt lymphoma. Even at high doses of
16 MBq this diabody RIC was well tolerated by NOD
Rag1(null) IL2rγ(null) (NRG) mice and did not reveal signs
of organ long-term toxicity 80 days post injection.
Combination therapy of the diabody RIC with unconjugated
anti-CD20 Rituximab demonstrated therapeutic efficacy in
established disseminated mantle cell lymphoma xenograft
models. When compared with the combination of the IgG
formatted (177)Lu anti-CD22 antibody and Rituximab, dual
targeted therapy with the diabody RIC achieved an improved
reduction of disease burden in the first nine days following
treatment. The data indicate that the PEGylated anti-CD22
diabody may have potential for extending the repertoire of
radiopharmaceuticals for the treatment of patients with
B-NHL.},
