Verducatib
Based on 1 Customer Validation
Verducatib (BI 1291583) is an orally active inhibitor of cathepsin C (also known as DPP1). Verducatib restores the protease-inhibitor balance by inhibiting the activation of neutrophil serine proteases, thereby alleviating pulmonary inflammation and regulating infection responses. Verducatib significantly reduces the risk (including severe exacerbations) and frequency of acute exacerbations in bronchiectasis (BE). Verducatib also improves lung function and quality of life, and shortens the duration of antibiotic use. The overall incidence of adverse events of Verducatib is comparable to that of placebo, with only slightly more mild-to-moderate cutaneous adverse events observed in the high-dose group, demonstrating promising clinical application potential.

Cathepsin C |
Verducatib (BI 1291583) (0.08, 0.4, 2, 10, 50 nM, pH 4.5) binds to recombinant human cathepsin C (CatC) in a reversible covalent manner, with binding kinetic parameters of kon 6.36×106 M-1s-1, koff 2.29×10-3 s-1, an equilibrium dissociation constant KD of 0.43 nM, and a binding half-life t1/2 of 5.19 min[3].
Verducatib (0.064-1000 nM; 48 h) concentration-dependently inhibits the production of active neutrophil elastase (NE) in human neutrophil progenitor U937 cells, with an IC50 of 0.7 nM. It shows no obvious cytotoxicity against U937 cells, with cell viability higher than 93% at all tested concentrations and an average cell viability of 98% at the highest concentration of 1000 nM[3].

Result:Inhibited the production of active neutrophil elastase (NE) in human neutrophil progenitor U937 cells, with an IC50 of 0.7 nM.
Verducatib (single dose; p.o.) exhibits rapid distribution to the target tissue bone marrow and slow clearance in the pharmacokinetic models of healthy mice and rats. Even at low doses, it achieves a distribution profile where bone marrow exposure is significantly higher than plasma exposure, and this property shows no obvious interspecies difference between the two species[3].

Animal Model:Female Crl:NMRI mice, LPS-challenged lung neutrophil influx model for bronchiectasis preclinical mechanism verification[3]
-
Dosage:0.005 mg/kg, 0.05 mg/kg, 0.5 mg/kg, 5 mg/kg
-
Administration:oral gavage twice daily on Days 1-5, 8 and 9, with final dose on Day 10 followed by nebulised E. coli LPS challenge
-
Result:Inhibited the production of active neutrophil elastase (NE) and cathepsin G (CatG) in bronchoalveolar lavage fluid (BALF) neutrophils in a dose-dependent manner.
The maximum inhibition rate of NE reached 97%, with an ED99 value of 1.5 mg/kg for NE inhibition, and the maximum inhibition rate of CatG reached 99%.
Showed statistically significant inhibition of NE activity compared with the vehicle control (p<0.001).
At 5 h after the final dose of 0.5 mg/kg, the mean exposure of BI 1291583 in bone marrow was 2981.7 nM, while the corresponding plasma exposure was 32.5 nM.
