Clinical Proof-of-conceptPhase 2a crossover design targets a clinically meaningful sweat chloride reduction without new safety signals, which would validate the NBD1 stabilization approach and materially lower development risk.
Combination Compatibility And TolerabilityDrug–drug interaction testing and pharmacokinetic and safety data indicate the candidate can be combined with standard CF therapy and achieves intended exposure at low doses, supporting both add-on and standalone development paths.
Translational Assay ValidationCalibration of the company's CF HBE assay to the industry standard creates a translational tool that guides dose selection and increases confidence in the probability of clinical success for NBD1 stabilizers.
