SYD1091 [Investigative]
Discovered Using Cell Line-derived Xenograft Model
| Experiment 1 Reporting the Activity Date of This ADC | [1] | ||||
| Efficacy Data | Tumor Growth Inhibition value (TGI) | ≈ 67.53% (Day 69) | Positive PSMA expression (PSMA+++/++) | ||
| Method Description |
Tumours were induced subcutaneously by injecting of 10,000,000 LnCap C4.2 cells in 200 uL of RPMI 1640 containing matrigel into the right flank of male CB17.SCID mice. Treatments were started when the tumors reached a mean volume of 100-200 mm3. Mice were randomized according to their individual tumor volume into groups and received a single i.v, 2 mg/kg inection of anti-PSMA ADC.

Revealed Based on the Cell Line Data
| Experiment 1 Reporting the Activity Date of This ADC | [1] | ||||
| Efficacy Data | Max inhibition rate (MIR) |
59.00%
|
Negative PSMA expression (PSMA-) | ||
| Method Description |
To assess the sensitivity towards cathepsin B, the ADCs were treated for 2 minutes and 4 hours with activated cathepsin B. To measure release of the respective free toxins DUBA or MMAE, PSMA-negative DU-145 cells (1,000 cells/well) was cultured with the ADCs for 6 days,and the cell viability was measured after 6 days using the CellTiter-GloTM (CTG) assay kit.
