  • Volunteer is a non-smoker or ex-smoker of at least 12 months' duration prior to screening with a history of less than 1 pack per year.

Exclusion criteria

  • Volunteers receiving chronic medication other than oral contraceptives;
  • Screening forced expiratory volume FEV1 is < 80% of the predicted value for their age, gender, height and race and/or their FEV1/FVC ration is below 70%;
  • Volunteers with significant occupational exposure to respiratory irritants or toxins
  • Upper respiratory tract infection within 30 days of the first study day, or lower respiratory tract infection within the last 3 months;
  • Volunteers taking any medication that may affect the respiratory tract within 30 days of the first study day;
  • Volunteers with a history of asthma

Treatment and study plan

PUR118

Drug

inhaled PUR118, BID

Primary outcomes

  1. Change from baseline in sputum cell counts and inflammatory markers

    Time frame: 6 hours post-initiation of ozone challenge

  2. Change from baseline in white blood cell and inflammatory biomarker counts in blood

    Time frame: 7 and 24 hours post-initiation of ozone challenge

Secondary outcomes

  1. Change from baseline in pulmonary function

    Time frame: all post-dose timepoints up to 24 hours post-initiation of ozone challenge

  2. Changes in clinical signs and symptoms from physical examination at baseline

    Time frame: Subjects will be followed for an expected average of 12 weeks

  3. Changes in clinical safety laboratory tests from baseline

    Time frame: Subjects will be followed for an expected average of 12 weeks

  4. Changes in vital signs from baseline

    Time frame: Subjects will be followed for an expected average of 12 weeks

  5. Changes in ECG from baseline

    Time frame: Subjects will be followed for an expected average of 12 weeks

  6. Number of subjects with adverse events
