Study summary

Statement of the problem:

Overprescription of antibiotics raises important public health issues because of the emergence of multiresistant bacteria by selection pressure. The results of the observational prospective study entitled "CAPA" on the description of 886 suspected cases of acute community-acquired pneumonia (CAP) treated in general practices in France confirm that, whatever the etiologic hypothesis and the results of the chest X-ray, these patients routinely receive antibiotics. Therefore, it is important to be able to distinguish cases of pneumococcal CAP in which early antibiotic treatment is justified from those cases for which another strategy could be considered.

Primary objective:

To identify the clinical, biological and radiological characteristics of patients with pneumococcal CAP amongst all patients with CAP radiologically confirmed, in general practice in France.

Design :

Prospective cross-sectional descriptive study.

Inclusion criteria. Adults older than 18 showing clinical signs suggestive of CAP (at least one sign of infection and at least one pulmonary sign) and able to realize chest X ray within 6 hours after prescription.

Patient follow-up procedures. Patients will be treated by standard of care according to French recommendations. After observing clinical signs suggestive of CAP, the physician prescribes a chest X-ray. Then, protocol-specific examinations (blood sample, oropharyngeal sample for multiplex polymerase chain reaction (PCR), sputum sample testing (induced expectoration if possible), urinary sample) will be performed on all out patients. Patients will be contacted again on day 28 to increase diagnostic certainty. For patients with clinical signs of CAP and hospitalized, the investigator will ask their consent to retrieve the hospital report, on or before day 28 and to be contacted on day 90.

Read the detailed description

The aim of the study is to enroll approximately 2000 patients with CAP in total. Approximately 1000 X-ray positive patients and 1000 X-ray negative patients will be enrolled over 18 months.

Investigating GPs will identify patients with clinical signs suggestive of CAP at clinic visits.

A chest X-ray will be prescribed in accordance with local standard of care practices for patients that do not require immediate hospitalization. Chest X-ray must be completed within the 6 hours following its prescription.

For the 1000 patients (patient enrolment will be monitored centrally) with a positive chest X-ray, all procedures will be undertaken according to the protocol. Patients will attend the local medical analysis laboratory for biological sample collection (blood, sputum, oropharyngeal swab for the PCR, and urine). If a patient has taken antibiotics prior to the clinic visit at which CAP is suspected, will only have urine samples collected.

As a diagnostic confirmation of the chest X-ray assessments, for the 1000 patients for whom the local radiologist will have diagnosed a parenchymal opacity compatible with CAP, 200 patients will be randomly selected by the clinical research organization (CRO Paris Descartes Necker Cochin). A central independent thoracic radiologist expert will re-read their chest X-ray. In case of insufficient agreement, all chest X-rays will be re-read.

Patients will be asked to complete and return a self-assessment questionnaire at day 7 (D7) and at day 14 (D14) on the number of work days missed, if any, interruption of occupational activity, and the number of days of restricted everyday activities or recreational.

Patients will be contacted by telephone at day 28, and day 90 if they are hospitalized between day 0 and day 28.

For the 1000 patients (patient enrolment will be monitored centrally) with a negative chest X-ray, no medical analysis will be performed. Only clinical examination data will be recorded. Patients will be contacted by telephone at day 28.

For patients who will be directly hospitalized before the completion of the additional examinations, they will be contacted by telephone at day 28 to retrieve the hospitalization report and at day 90.

Control Patients will be included for the assessment of Pneumococcal urine antigen detection (UAD) Assay: in the two weeks following the inclusion of a patient with CAP, investigators should include a control patient according to the control patient inclusion / exclusion criteria. For these healthy patients, the number of inclusion is limited to 400.

Terms in these criteria, in plain language(7)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

COPD

Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Dec 2017 to primary completion in Dec 2019, 23 months.

Of 38 observational studies under Community-Acquired Pneumonia, half reached primary completion within 31 months of starting (the median), counting those still running; a quarter within 22 and three quarters within 57. This study's 23 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 12, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
