Brenetafusp
Based on 1 Customer Validation
Brenetafusp is a TCR/anti-CD3 bispecific fusion protein, consisting of a TCR targeting the PRAME peptide and an anti-CD3 scFv effector domain. Brenetafusp redirects CD3+ T cells to kill PRAME+ tumor cells. Brenetafusp can be used in research related to cutaneous melanoma, non-small cell lung cancer, ovarian cancer, endometrial cancer, triple-negative breast cancer, and small cell lung cancer.

Brenetafusp (10-13-10-8 M) potently activates T cells in a dose-dependent manner against HLA-A*02:01+ PRAME+ MEL624, MEWO, SKMEL5, and C32 melanoma cell lines, with EC50 values ranging from 12.4 to 98.0 pM[1].
Brenetafusp (10-14-10-9 M) potently mediates T cell-directed cytotoxicity against HLA-A*02:01+ PRAME+ MEL624, MEWO, and C32 melanoma cell lines, with EC50 values ranging from 2.99 to 20.4 pM[1].
Brenetafusp (10-13-10-8 M) potently activates T cells in a dose-dependent manner against HLA-A*02:01+ PRAME+ NCI-H1755 and NCI-H1703 NSCLC cell lines, with EC50 values of 17.9 and 76.9 pM, respectively[1].
Brenetafusp (10-14-10-9 M) potently mediates T cell-directed cytotoxicity against HLA-A*02:01+ PRAME+ NCI-H1755 and NCI-H1703 NSCLC cell lines, with EC50 values of 1.3 and 4.4 pM, respectively[1].
Brenetafusp (10-13-10-8 M) potently activates T cells in a dose-dependent manner against HLA-A*02:01+ PRAME+ OV56 and COV318 ovarian cancer cell lines, with EC50 values of 2.4 and 17.4 pM, respectively[1].
Brenetafusp (10-14-10-9 M) potently mediates T cell-directed cytotoxicity against HLA-A*02:01+ PRAME+ OV56 and COV318 ovarian cancer cell lines, with EC50 values of 1.6 and 10.5 pM, respectively[1].
Brenetafusp (10-1000 pM) effectively redirects T cells to induce dose-dependent apoptosis in HLA-A*02:01+ PRAME+ patient-derived tumor organoids[1].
Brenetafusp (10-13-10-8 M) mediated T cell activation is dependent on PRAME expression in MEL624 melanoma cells, with robust activity in parental cells, reduced activity in PRAME KO cells, and dose-dependent restored activity in PRAME-rescued KO cells[1].
Brenetafusp (10-100 pM; 80 hours) redirects PD-1+ exhausted TILs to kill PD-L1+ MEL624 melanoma cells, with impaired activity that is fully rescued by anti-PD-1 antibody[1].
Brenetafusp (up to 10 nM for bronchial epithelial cells; down to 1 nM for melanocytes) shows minimal reactivity against primary normal human bronchial epithelial cells and melanocytes, demonstrating specificity for PRAME+ tumor cells[1].

Cell Line:PD-1+ and PD-1- tumor-infiltrating lymphocytes (TILs) from melanoma biopsies, co-cultured with PD-L1+ or PD-L1- MEL624 melanoma cells
-
Concentration:10 pM, 100 pM
-
Incubation Time:80 hours
-
Result:Mediated cytotoxicity by PD-1+ TILs against PD-L1+ MEL624 cells that was 3-10-fold lower than against PD-L1- cells at 100 pM; co-incubation with anti-PD-1 antibody fully restored this cytotoxicity.
Unconjugated
The product can be reconstituted/diluted with sterile PBS or saline.

Flow cytometric analysis of 1X106 Jurkat cells with Brenetafusp (HY-P990717, red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. Then stained with the primary antibody at 1/50 dilution for an hour at 4℃. Alexa Fluor 488-conjugated AffiniPure Goat Anti-Human IgG H&L (HY-P83776) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Cells without incubation with primary antibody were used as the unlabeled control (black). -
