Study to Evaluate the Safety of CB-280 in Patients With Cystic Fibrosis

Status Completed

Clinical Trial Summary

This is a phase 1b multiple ascending dose escalation study to evaluate the safety and tolerability of arginase inhibitor CB-280 in subjects with cystic fibrosis.

Clinical Trial Description

Study CX-280-202 is a Phase 1b, randomized, double-blind, placebo-controlled, multiple ascending dose escalation study of CB-280 in adult subjects with cystic fibrosis and chronic infection with Pseudomonas aeruginosa. The study will evaluate the safety, pharmacokinetics, pharmacodynamics, and biological activity of CB-280 in approximately 32 adult patients with cystic fibrosis. There are four planned sequential dose escalation cohorts of 8 subjects each, randomized 6:2 to receive CB-280 or matched placebo at doses of 50 mg, 100 mg, 200 mg, or 400 mg administered twice daily for 14 days. Intermediate dose levels may be evaluated based on emerging safety data at the planned dose levels. ;
