Full List of Activity Data of This Peptide-drug Conjugate
Identified from the Human Clinical Data
| Experiment 1 Reporting the Activity Data of This PDC | [1] | ||||
| Indication | Triple-negative breast cancer | ||||
| Efficacy Data | Tumor Growth Inhibition value (TGI) |
43% (Day 14)
|
|||
| Administration Time | 4-injection regimen (on day 0, 2, 4, and 6) | ||||
| Administration Dosage | 10 mg/kg | ||||
| Evaluation Method | Tumor volume detection assay | ||||
| MOA of PDC |
N38-HKD increases infiltration, activity, and viability of CD8+T cells, and thus inhibits the growth of primary tumors and pulmonary metastasis. This study highlights the synergistic modulation of cancerous cells and TECs with integrin-targeting PDC filaments as a promising strategy for TNBC chemoimmunotherapy.
|
||||
| Description |
SN38-HKD/RGDR slowed the 4T1 tumor growth by 74%, while irinotecan and SN38-HKD only showed 28% and 43% tumor growth inhibition, respectively, which was further confirmed by its capability in reducing tumor burden.
