In this week's episode, Blood editor Dr. Laurie Sehn interviews Drs. Camille Laurent and Christine Bezombeson on their latest article published in Blood titled "Patient-derived lymphoma spheroids reveal predictive markers of glofitamab resistance in relapsed/refractory B-NHL." By using patient-derived lymphoma spheroids as an ex vivo platform, they identify key mechanisms of resistance to the bispecific T-cell engager glofitamab in B-cell non-Hodgkin lymphoma, showing that higher CD8 T-cell abundance and cytotoxic activity is associated with better therapeutic responses, while increased T follicular helper (Tfh) cells correlate with resistance. The authors further show that resistance could be overcome by depleting Tfh cells or combining glofitamab with TIGIT (T-cell immunoreceptor with Ig and ITIM domains) blockade, highlighting promising strategies to improve responses to T-cell engager therapies.
