The CD37 targeting radioimmunoconjugate 177Lu-lilotomab satetraxetan (Betalutin®) is currently being evaluated as monotherapy in a clinical phase 2b trial for patients with follicular lymphoma (FL) and in a phase 1 trial for patients with diffuse large B-cell lymphoma (DLBCL), as well as in a phase 1b trial in combination with rituximab for patients with relapsed/refractory FL. These findings may be of potential relevance for ongoing clinical trials of 177Lu-lilotomab satetraxetan in relapsed, ASCT-non-eligible DLBCL, and may also be more generally applicable to other 177Lu-based RITs and alternative radionuclide utilizing targeted therapies. Future pre-clinical investigations are required to elucidate the potential application of CDK1/2 and AURKA/B inhibitors as a strategy to revert RIT resistance in TP53 deficient cancers.
