NCT01272635

Brief Summary

This protocol is comprised of two separate, but linked, clinical trials for treating preschool-aged children with recurrent severe episodes of wheezing. The first study (APRIL) will try to prevent wheezing illness from developing using azithromycin. If a wheezing illness does occur, the second trial (OCELOT) will try to decrease the severity of symptoms using oral corticosteroids.

Outcome Measures

Primary Outcomes (2)

  • Progression to Clinically Significant Lower Respiratory Tract Symptoms

    Progression to clinically significant lower respiratory tract symptoms defined by: (1) having symptoms that were more than mild after 3 albuterol administrations over 1 hour, or (2) requiring albuterol administrations more often than once every 4 hours, or (3) requiring more than 6 albuterol treatments over a 24-hour period, or (4) having moderate to severe cough or wheeze for 5 or more days since study medication was initiated.

    14 days after initiation of APRIL therapy

  • OCELOT: Pediatric Respiratory Assessment Measure

    The Pediatric Respiratory Assessment Measure (PRAM) is a composite outcome with scores ranging from 0-12 with higher numbers representing worse symptoms. The score is calculated as the sum total of the follow five elements: (1) scalene retractions, (2) suprasternal retractions, (3) wheezing, (4) air entry, (5) oxygen saturation. A complete description can be found in: Ducharme FM, Chalut D, Plotnick L, et al. The Pediatric Respiratory Assessment Measure: a valid clinical score for assessing acute asthma severity from toddlers to teenagers. J Pediatr 2008;152:476-80.

    36-72 hours after initiation of OCELOT therapy

Secondary Outcomes (4)

  • Asthma Related Symptoms Among RTI Progressing to Severe LRTI

    14 days after initiation of therapy

  • Absence From School, Daycare, and/or Parental Work

    14 days after initiation of therapy

  • Urgent Care Visits, ED Visits and Hospitalizations

    14 days after initiation of therapy

  • Drug Related Side Effects

    14 days after initiation of therapy

Eligibility Criteria

Age12 Months - 71 Months
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • months of age.
  • Recurrent significant wheezing in the past year (any of the following):
  • \>3 episodes, ≥1 of which was clinically significant\*; OR
  • \>2 clinically significant\* episodes; OR
  • \>4 months of daily controller therapy AND \>1 clinically significant\* episode.
  • \* Clinically significant episode: requiring any of the following: (1) systemic corticosteroids (oral or injectable), (2) unscheduled physician office visit, (3) ED visit, (4) urgent care visit, or (5) hospitalization.
  • Up to date with immunizations, including varicella (unless the subject has already had clinical varicella). If the subject needs varicella vaccine, this will be arranged with the primary care physician and must be received prior to randomization.
  • Willingness to provide informed consent by the child's parent or guardian.

You may not qualify if:

  • \>4 courses of systemic corticosteroids in past 12 months.
  • More than 1 hospitalization for wheezing illnesses within the preceding 12 months.
  • Use of long-term controller medications for asthma, including inhaled corticosteroids, leukotriene modifiers, cromolyn/nedocromil, or theophylline for more than 8 months (cumulative use) in the past 12 months.
  • Current use of higher than step 2 NAEPP asthma guideline therapy (e.g. medium-high dose ICS alone or combination therapy of low-medium-high dose ICS + LABA, montelukast, theophylline or cromolyn). NOTE: children who have evidence of well-controlled symptoms immediately preceding study entry while receiving Step 2 controller therapy (presence of self-reported symptoms on average no more than 2 times per week and less than 2 nights per month of nocturnal awakenings, requiring albuterol, during the 4 weeks preceding visit 1) may be enrolled and will have their controller therapy discontinued upon study entry.
  • Use of OCS in the past 2 weeks.
  • Daily symptoms or \>2 nocturnal awakenings, requiring albuterol, on average in the last 2 weeks.
  • Use of antibiotics in the past month.
  • Current treatment with antibiotics for diagnosed sinus disease.
  • Participation presently or in the past month in another investigational drug trial.
  • Evidence that the family may be unreliable or nonadherent, or may move from the clinical center area before trial completion.
  • Contraindication of use of systemic corticosteroids or azithromycin.
  • Clinically relevant gastroesophageal reflux.
  • Concurrent medical conditions other than asthma that are likely to require oral or injectable corticosteroids during the study.
  • If receiving allergy shots, change in dose within the past 3 months.
  • Participants who meet any of the following criteria are NOT eligible for enrollment, and may not be re-enrolled:
  • +8 more criteria
