Effect of Pre-Treatment With Cromolyn or Albuterol on Response to PUL-042 Inhalation Solution (PUL-042)


This study evaluates the effect of pre-treatment with either cromolyn sodium or albuterol sulfate on the safety and tolerability or PUL-042 Inhalation Solution in healthy subjects.

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Crossover Assignment
    • Primary Purpose: Treatment
    • Masking: None (Open Label)
  • Study Primary Completion Date: January 2016

Detailed Description

Healthy subjects (8 per cohort) will be randomized to either pre-treatment or no pre-treatment (4 per group). The initial cohort will receive pre-treatment with cromolyn sodium. Subjects will be followed for 2 weeks for safety and tolerability, undergo a 2 week washout period and then be assigned to the alternative treatment (i.e., subjects who received cromolyn sodium prior to PUL-042 inhalation solution will not receive pretreatment) and then followed for an additional 2 weeks.

Subsequent cohort will receive pre-treatment with albuterol sulfate in a like manner.
