What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants With Rhinovirus PCR-Positive Colds

    The common cold was defined as moderate or severe rhinorrhea and at least one other cold symptom of moderate to severe intensity for at least 1 day, together with rhinovirus-positive polymerase chain reaction (PCR), after a participant had temporal exposure to an index case. PCR+ was defined as positive or equivocal outcome of the picornavirus test any time after randomization.

    Measured: From time of exposure to index case to end of Follow-up Period (21 days)

  2. Percentage of Participants With Asthma Exacerbations Together With Rhinovirus-Positive PCR

    Asthma exacerbation was defined as a participant having one of the following:

    1. 0.5 point or more increase in the Asthma Control Questionnaire (ACQ) from Baseline at Day 7. The ACQ is a validated instrument containing 7 questions to assess asthma control which incorporates symptoms, beta-agonist use, and spirometry. Participants recall their experiences during the previous 7 days and respond to each question using a 7-point scale. The items are equally weighted and the ACQ score is the mean of the 7 items and therefore ranges between 0 (well controlled) and 6 (extremely poorly controlled). The ACQ completed on the day of exposure was the Baseline ACQ.
    2. Any change to asthma treatment as prescribed by a physician, unscheduled contact (either office visit or phone contact where medication was changed for asthma symptoms), emergency room visit, or hospitalization.

    PCR+ was defined as positive or equivocal outcome of the picornavirus test any time after randomization.

    Measured: From time of exposure to index case to end of Follow-up Period (21 days)

Secondary outcomes (8)
  1. LS Mean Change From Baseline in the Asthma Control Questionnaire (ACQ)

    The ACQ is a validated instrument containing 7 questions to assess asthma control which incorporates symptoms, beta-agonist use, and spirometry. Participants recall their experiences during the previous 7 days and respond to each question using a 7-point scale. The items are equally weighted and the ACQ score is the mean of the 7 items and therefore ranges between 0 (well controlled) and 6 (extremely poorly controlled). The ACQ completed on the day of exposure was the Baseline ACQ. Pooled standard deviations (SDs) and least square (LS) means were calculated based on an analysis of variates (ANOVA) model.

    Measured: Baseline through the Final Visit (Day 21)

  2. LS Mean Change From Baseline in Forced Expiratory Volume in 1 Second (FEV1)

    FEV1 is the volume of air that can forcibly be blown out in one second, after full inspiration. Pooled SDs and LS means were calculated based on an ANOVA model.

    Measured: Baseline through the Final Visit (Day 21)

  3. LS Mean Change From Baseline in Peak Expiratory Flow (PEF) in AM

    PEF is a person's maximum speed of expiration as measured with a peak flow meter and was measured twice daily in the morning (AM) and evening (PM). Pooled SDs and LS means were calculated based on an ANOVA model.

    Measured: Baseline through the Final Visit (Day 21)

  4. LS Mean Change From Baseline in Peak Expiratory Flow (PEF) in PM

    PEF is a person's maximum speed of expiration as measured with a peak flow meter and was measured twice daily in the morning (AM) and evening (PM). Pooled SDs and LS means were calculated based on an ANOVA model.

    Measured: Baseline through the Final Visit (Day 21)

  5. LS Mean Change From Baseline in Total Cold Symptom Score

    Participants entered their cold symptoms into an e-diary twice daily beginning at the Screening Visit through completion of the study. The total cold symptom score was the sum of 6 scores for rhinorrhea, nasal congestion, cough, score throat, malaise, and myalgia. Each symptom is scored as follows: 0 = none-sign/symptom is not present, 1 = mild-sign/symptom noticeable but did not bother me or interfere with my normal daily activities/sleep, 2 = moderate- sign/symptom annoying and may have interfered with my normal daily activities/sleep, or 3 = severe-symptom very uncomfortable and interfered with most or all of my normal daily activities/sleep. The total score ranges from 0 to 18, with increasing scores reflecting more severe colds. Baseline values were defined as the average of the last seven assessments prior to randomization (before exposure to an index case). Pooled SDs and LS means were calculated based on an ANOVA model.

    Measured: Baseline through the Final Visit (Day 21)

  6. LS Mean Change From Baseline in Total Asthma Symptom Score

    Participants entered their asthma symptoms into an e-diary twice daily beginning at the Screening Visit through completion of the study. The total asthma symptom score was the sum of 3 scores for wheeze, cough, and dyspnea. Each symptom is scored as follows: 0 = none-sign/symptom is not present, 1 = mild-sign/symptom noticeable but did not bother me or interfere with my normal daily activities/sleep, 2 = moderate- sign/symptom annoying and may have interfered with my normal daily activities/sleep, or 3 = severe-symptom very uncomfortable and interfered with most or all of my normal daily activities/sleep. The total score ranges from 0 to 9, with increasing scores reflecting more severe asthma. Baseline values were defined as the average of the last seven assessments prior to randomization (before exposure to an index case). Pooled SDs and LS means were calculated based on an ANOVA model.

    Measured: Baseline through the Final Visit (Day 21)

  7. LS Mean Change From Baseline in Short-acting Beta-Agonist (SABA) Rescue Medication Usage

    SABAs such as albuterol were permitted during the study as rescue medication and required a 6-hour washout prior to each visit. Participants entered their asthma medication use into an e-diary twice daily beginning at the Screening Visit through completion of the study. The Baseline for diary symptoms was the average of the last seven assessments prior to Randomization. Pooled SDs and LS means were calculated based on an ANOVA model.

    Measured: Baseline through the Final Visit (Day 21)

  8. LS Mean Change From Baseline in Asthma-Related Sleep Interference

    Participants entered their asthma-related changes in sleep into an e-diary once daily (in the morning) beginning at the Screening Visit through completion of the study. Changes from Baseline in asthma-related sleep interference were determined using the following question: How did cold and asthma symptoms interfere with your sleep? The question was scored as follows: 0 = None, no interference with sleep at all, 1 = Mild, not annoying or troublesome, adequate amount of sleep, 2 = Moderate, interfered somewhat with sleep, woke up a few times, average sleep, 3 = Severe, substantially interfered with sleep, poor sleep. The Baseline for diary symptoms was the average of the last seven assessments prior to Randomization. Pooled SDs and LS means were calculated based on an ANOVA model.

    Measured: Baseline through the Final Visit (Day 21)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Pleconaril in people with Asthma and Common Cold, run by Merck Sharp & Dohme LLC.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 15 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 16 Jul 2015. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 31 Oct 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of Participants With Rhinovirus PCR-Positive Colds (time frame: From time of exposure to index case to end of Follow-up Period (21 days)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Jul 2015.
