About this study

Official title: Phase III Clinical Trial - Efficacy and Safety Assessment of a Compound Acetaminophen, Chlorpheniramine and Phenylephrine Combination in the Symptomatic Treatment of Common Cold and Flu-Like Syndrome in Adults

The aim of this study is to assess the efficacy and safety of an anti-cold preparation compounded by acetaminophen, chlorpheniramine and phenylephrine for the treatment of cold and flu symptoms in healthy individuals in a randomized, double-blind, placebo-controlled clinical trial.

Read the detailed description

Upper respiratory infections are rather frequent in the population, and their treatment consists, in most cases, in the use of symptomatic drugs. Acetaminophen is widely used as an analgesic and antipyretic, whereas chlorpheniramine is an antihistaminic and phenylephrine is a vasoconstrictor with decongestioning activity. The aim of this study is to assess the efficacy and safety of an anti-cold preparation, currently commercialized in Brazil by the name Resfenol, compounded by acetaminophen, chlorpheniramine and phenylephrine for the treatment of cold and flu symptoms in healthy individuals in a randomized, double-blind, placebo-controlled clinical trial.

Healthy volunteers are recruited through panels fixated at Hospital de Clínicas de Porto Alegre, in Brazil, and must answer a screening questionnaire at first contact. One hundred and forty six patients who met the inclusion criteria were included and, after baseline clinical and laboratory evaluation, were randomized to receive either the active intervention or placebo, 5 times a day, at 4 hour intervals, during 48 to 72 hours, depending on patient availability to show up for re-evaluation. Patients also received acetaminophen as a co intervention, to be taken only in case of persisting symptoms.

Patients answered, during treatment, several symptom questionnaires contained in a diary, and followup was performed at days 3 or 4 (clinical and laboratory evaluation) and 10 or 11 (clinical followup). Axillary temperature was assessed along with every dose with a thermometer provided by the study and registered in the diary.

Primary endpoint consists in the mean symptom scores, assessed through questionnaires in patient diary, baseline and followup. Secondary endpoints are global duration of symptoms, time of return to usual activities, use of co intervention for symptom relief, improval of fever and adverse effect evaluation.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ResfenolDrug

    Also called Anti-cold preparation, Acetaminophen, Chlorpheniramine, Phenylephrine

    Each capsule of the active drug contains 400mg of acetaminophen, 4mg of chlorpheniramine and 4mg of phenylephrine. Patients will receive up to five capsules a day.

  • PlaceboDrug

    Patients in this group will receive placebo capsules up to five times a day, with the exact same taste and appearance as the active comparator.

  • Co interventional acetaminophenDrug

    Also called Rescue medication, Acetaminophen, Paracetamol, Co intervention

    All patients received, along with the assigned intervention, 12 acetaminophen 500mg pills, that they were instructed to take only in case of persisting PAIN or FEVER, up to 4 times a day.

Study groupRoleWhat they receive
ResfenolActive comparatorPatients in this arm will receive 15 capsules containing a combination described below. They are instructed to take one capsule at 7, 11, 15, 19 and 23h every day, starting after baseline evaluation. The duration of the treatment goes from 48 to 72 hours, depending on patient availability for the second evaluation. Patients also receive co interventional acetaminophen pills, that they are allowed to take in case of persisting pain or fever, up to 4 times a day.

PlaceboPlacebo comparatorPatients in this arm will receive 15 capsules of placebo, that they are instructed to take in the same posology and in the same duration than the active comparator. Patients also receive co interventional acetaminophen pills, that they are allowed to take in case of persisting pain or fever, up to 4 times a day.

What is being measured

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

  1. Symptom improval assessed by questionnaires concerning headache, muscle ache, rhinorrhea, nasal obstruction, sneezes, cough, sore or irritated throat, hoarseness and fever, rated by patient himself in a scale from 0 to 4, being 0-absence and 4-severe.

    Measured: Questionnaires were answered at baseline and 1st followup to the investigator and during treatment at every dose, 5 times a day, from day 1 to 3/4, through patient's diary.

Secondary outcomes (5)
  1. Global duration of symptoms, assessed by the investigator through direct questioning at followup visits.

    Measured: Day 3/4 and, if no relief yet, day 10/11.

  2. Time of return to usual activities, such as work or gym, assessed by the investigator through direct questioning at followup visits.

    Measured: Day 3/4 and, if no relief yet, day 10/11.

  3. Use of co intervention for symptom relief during treatment, registered by the volunteer in patient diary, with day and hour of ingestion.

    Measured: Assessed during treatment (day 1 to 3/4) by patient diary and questioned by investigator at 1st followup visit.

  4. Improval of fever by reduction of axillary temperature to less than 38,1°C.

    Measured: Assessed by investigator at baseline and 1st followup visit and by patient (with termometer provided by the study) along with every dose, 5 times a day, from day 1 to 3/4, registered in patient diary.

  5. Adverse effect appearance during and until 7 days after treatment, assessed through patient's report in the diary or followup visit, through physical evaluation at followup and by laboratory exams.

    Measured: Days 1 to 3/4 through patient diary, and followup at days 3/4 an 10/11.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Resfenol and Co interventional acetaminophen in people with Common Cold and Flu-like Syndrome, run by Hospital de Clinicas de Porto Alegre at 1 site in Brazil.

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 6 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: status not confirmed, as of the sponsor's last update on 16 Jul 2009. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.

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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

Are results available for this study?

Results are not available in the source record.

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

Contact Paulo D Picon, MD, PhD (55 xx 51 33598752, paulopicon@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Symptom improval assessed by questionnaires concerning headache, muscle ache, rhinorrhea, nasal obstruction, sneezes, cough, sore or irritated throat, hoarseness and fever, rated by patient himself in a scale from 0 to 4, being 0-absence and 4-severe. (time frame: Questionnaires were answered at baseline and 1st followup to the investigator and during treatment at every dose, 5 times a day, from day 1 to 3/4, through patient's diary.). 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 2009.
