  Purpose

During this proposed clinical trial, the investigators intend to evaluate the pharmacodynamic anti-inflammatory properties and safety of TPI ASM8, by investigating the effect on sputum eosinophils and the airway responses during an allergen challenge at different dose levels.

Primary Outcome Measures:
  • Sputum eosinophils (%) on Day 4 versus Screening for each dose level. [ Time Frame: 7 and 24 hrs post-allergen challenge ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Safety and tolerability. [ Time Frame: Throughout the study ] [ Designated as safety issue: Yes ]
  • Plasma and sputum pharmacokinetic profile at the two highest dose levels. [ Time Frame: Dose level 3 and 4 ] [ Designated as safety issue: No ]

Detailed Description:

The early and late asthmatic response were both significantly attenuated by the highest dose of ASM8. The methacholine challenge and other parameters (ECP, mRNA knockdown on CCR3 and B-Chain of IL-3-Il-5 and GMCSF were attenuated by ASM8.
