Understanding the complexities of neuroendocrine prostate cancer (NEPC) is crucial for advancing diagnosis and treatment. Insights into lineage plasticity and novel diagnostic tools, including PET imaging and liquid biopsies, are paving the way for more effective management strategies.

Twenty-seven (27) children with heavily pretreated neuroblastoma (12 with refractory disease, 14 with relapsed disease, and one with a complete response at the end of first-line therapy) were enrolled in this academic, phase 1-2 clinical trial to test autologous, third-generation GD2-CAR T cells expressing the inducible caspase 9 suicide gene (GD2-CART01). The use of GD2-CART01 in the treatment of high-risk neuroblastoma was feasible and safe. Treatment-related toxic effects emerged, and the suicide gene was activated to control side effects. GD2-CART01 may have long-term antitumor activity.

Reversal of HLA-I loss is crucial for an effective antitumor cytotoxic T cell response. Thus, HLA-I–upregulating drugs could augment immunotherapy response. The authors describe here a small-molecule USP7 inhibitor as a promising avenue for pharmacologic upregulation of HLA-I in MCC.

MDM2 is an important regulator of p53 and can be an effective therapeutic target in cancers. Pharmacological inhibition of MDM2 for stabilization of p53 has been of interest for several years and several MDM2 inhibitors targeting the MDM2-p53 interaction are currently in clinical trials. Approximately 80% of Merkel cell carcinoma (MCC) tumors have wild type p53 and could potentially respond to treatment with MDM2 inhibitors. In this study, milademetan showed a dose-dependent inhibition of tumor growth in MKL-1 xenograft and patient-derived xenograft models and is a potent MDM2 inhibitor in MCC.
