Experiment 1 Reporting the Activity Data of This PDC [1]
Indication Triple-negative breast cancer
Efficacy Data Tumor Growth Inhibition value (TGI)
74% (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/RGDR 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.
