Detailed Description:
This is a phase 2a, randomized, double-blind, placebo-controlled, multi-dose, 2-way cross-over study designed to examine the effect of IPI-145 on lung function and inflammatory indices in mild, allergen-reactive asthmatic subjects undergoing allergen challenge.

Ages Eligible for Study:   18 Years to 60 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Male or female adults between 18 and 60 years of age
  • Diagnosis of asthma (mild) for at least 6 months prior to Screening
  • Forced expiratory volume in one second (FEV1) ≥70% of predicted value at Screening

  • Acute asthma exacerbations within 6 weeks prior to Screening
  • Use of any medication for the treatment of asthma other than a short-acting β2 agonist (as needed) within the 4 weeks prior to Screening
  • Participation in another clinical study within minimum of 30 days prior to study Screening
  • A positive screen result for active or latent tuberculosis
  • A history of cardiovascular disease
  • The concomitant use of acid-reducing agents and cholinesterase inhibiting medication
  • Inadequate hepatic function defined by Aspartate Aminotransferase (AST) and/or Alanine Aminotransferase (ALT) greater than 1.5 times greater limit of normal (ULN)
  • Inadequate renal function defined by serum creatinine greater than 2.0 milligrams/dL
