    MUC1-C INTEGRATES CHRONIC ACTIVATION OF INTERFERON PATHWAYS WITH CHROMATIN REMODELING IN TREATMENT RESISTANCE OF TRIPLE-NEGATIVE BREAST CANCER (SABCS 2023)
    In support of these results, targeting MUC1-C in wild-type BRCA1/2 TNBC cells enhanced carboplatin-induced DNA damage and loss of self- renewal capacity. In addition, MUC1-C was necessary for DNA damage resistance, self-renewal and tumorigenicity of olaparib-resistant BRCA1-mutant TNBC cells...As one example, an allogeneic anti-MUC1-C CAR T cell using MAb 3D1 sequences is undergoing Phase I evaluation for the treatment of MUC1-C-expressing cancers (NCT05239143: P-MUC1C-ALLO1 Allogeneic CAR-T Cells in the Treatment of Subjects with Advanced or Metastatic Solid Tumors). In addition, anti-MUC1-C huMAb3D1-MMAE ADCs are under development by the NCI NExT Program for IND-enabling studies and performing early phase clinical trials in patients with TNBC.

    Development of an allogeneic CAR-T targeting MUC1-C (MUC1, cell surface associated, C-terminal) for epithelial derived tumors (ESMO-IO 2022)
    In early phase I experience, P-MUC1C-ALLO1 is safe and tolerable with an early signal of efficacy at a low starting dose. P-MUC1C-ALLO1 phase I trial enrollment is on-going.
