CAR T cells recently showed incredible clinical response targeting CD19 and CD22 in hematological malignancies.

In the present study, we demonstrate that the immune checkpoint molecule B7-H3 (CD276) is aberrantly expressed on NB cells. Second generation CD276-CAR-engineered but not parental NK-92 cells were capable of specific and long-term elimination of NB cells in vitro while sparing CD276-negative cancer cells. Furthermore, CD276-CAR NK-92 cells showed increased cytotoxicity in a three-dimensional NB spheroid model which can recapitulate in vivo morphology as well as cell connectivity, polarity, gene expression, and tissue architecture, thereby, bridging the gap between in vitro and in vivo models. CD276-CAR NK-92 cells produced a multitude of NK effector molecules as well as pro-inflammatory cytokines that can stimulate the immune system. CD276-CAR surface expression and cytotoxic effector function remained stable for more than 6 months.

Despite an improvement in OS over the past 2 decades, most patients do experience disease relapse. A subset of patients who experience an early disease relapse within 1-2 years posttransplant, and considered functional high-risk. Recent findings implicated high-risk cytogenetic features and minimal residual disease as negative prognostic factors, each independently associated with early relapse among autologous stem cell transplant recipients(ASCT). The spectrum of disease relapse could range from asymptomatic/biochemical to more aggressive forms such as plasma cell leukemia. Hence, it is imperative that therapy be tailored based on these patterns of relapse upon presentation. The past few years have witnessed an explosion in the armamentarium of second-line agents for the treatment of relapsed MM. Accordingly, choosing the optimal regimen has become quite challenging for the practicing clinician. In this review, we outline the approach for therapy selection, which takes into account underlying comorbid conditions, duration of response, presence of high-risk features, etc Due to a better understanding of disease biology coupled with the advances in molecular techniques, the treatment landscape of relapsed MM (posttransplant) will most likely continue to evolve. Novel agents with distinct modes of action, such as immune therapies and novel oral agents are undergoing investigation in the relapsed setting.
