In this issue of Blood, Ferreri et al report preliminary results from the INGRID trial regarding the feasibility and safety of using engineered tumor necrosis factor-α for increasing blood-brain barrier permeability in patients with relapsed or refractory primary central nervous system (CNS) lymphoma.1 The authors demonstrate that treatment with tumor necrosis factor coupled with NGR (NGR-hTNF), a drug that targets CD13 on tumor blood vessels, followed by rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) is safe, selectively increases permeability of the blood-brain barrier (BBB) in the tumor regions, and is associated with radiographic responses.
