Identification of the Ki-1 antigen (CD30) as a novel therapeutic target in systemic mastocytosis

Abstract: Key Points• In a majority of patients with advanced SM, neoplastic MCs express the target receptor CD30.• The CD30-targeting drug brentuximab-vedotin blocks growth and survival in CD301 neoplastic MCs which favors drug development in advanced SM.The Ki-1 antigen (CD30) is an established therapeutic target in patients with Hodgkin lymphoma and anaplastic large-cell lymphoma. We have recently shown that CD30 is expressed abundantly in the cytoplasm of neoplastic mast cells (MCs) in patients with advanced systemi… Show more

“…In initial investigations, CD30 was found to be primarily expressed in MCs in advanced SM (62). However, although a correlation does exist, CD30 is not an absolute marker of advanced SM (ASM, MCL, SM-AHN), but is also detectable in MCs in many patients with ISM (59,63). CD30 may thus not be an optimal grading-marker in SM, but may qualify as a new minor criterion of SM, similar to CD25.…”

“…Such MCL-initiating stem cells have recently been identified in advanced SM (98). One effective approach to kill such quiescent (stem) cells may be to apply antibody-based toxin conjugates or other targeted antibodies (63,99,100). The CD30 antibody-based drug brentuximab-vedotin has recently been considered for the treatment of patients with advanced SM (63) and a clinical trial in patients with CD30+ ASM and MCL has recently been initiated in the USA.…”

“…[65][66][67][68][69][70][71] Antibody-based drugs directed against these targets may induce cell lysis or apoptosis in neoplastic MCs. 66,69,70 In addition, initial clinical observations suggest that antibody-based drugs exert antineoplastic effects in patients with advanced SM. 72,73 A summary of surface markers and potential targets expressed by neoplastic MCs is shown in Figure 1 and supplemental Table 5.…”

“…CD30 has been targeted with some success for relapsed hematological malignancies. CD30 can be expressed on the cell surface and in the cytoplasm but correlation between surface expression of CD30 and expression of cytoplasmic CD30 remains unclear (Blatt et al, 2015). CD30 targeting has shown to produce growth inhibition (G2/M cell cycle arrest) and apoptosis in neoplastic cells.…”
