Therefore, a conjugate that targets a different antigen could be desirable. Lutetium-177 [177Lu]-lilotomab satetraxetan (Betalutin®, previously known as 177Lu-DOTA-HHl) is a novel conjugate in which the murine mAb lilotomab targets CD37 receptors expressed on malignant B-cells, and 177Lu is a beta-emitter with a mean beta energy of 0.133 MeV (mean and max beta-range in water: 0.23 and 1.9 mm). CD37 is a 31 kDa transmembrane protein that belongs to the tetraspanin family. It has a bivalent role on the phosphatidylinositol 3’-kinase (PI3K)/AKT survival pathway and of humoral immunity. As CD37 is highly expressed in NHL cells, it represents an attractive molecule for targeted therapy.
177Lu-lilotomab is currently tested in a clinical phase 2b trial for the treatment of relapsed indolent B-cell NHL with promising safety and efficacy data especially in patients with FL. An enhancement of the effect of 177Lu-lilotomab would be very valuable.
