Results from a Phase 2 clinical trial have been published, demonstrating that a drug candidate -- AF-219 -- reduced daytime cough frequency by 75 percent compared to placebo in patients with treatment-refractory chronic cough. AF-219 is a selective, non-narcotic, orally administered P2X3 receptor antagonist targeting the mechanism by which certain nerve fibers become hyper-sensitized.
