What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This observational study is developing a computer model to identify different types of bronchiectasis in adults. Researchers will collect health data from 750 participants over time to see if they can predict disease patterns. No treatments or interventions are given; participants receive standard care.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could help doctors better predict disease patterns and personalize care for people with bronchiectasis.
What could go wrong
This is an observational study, so it does not test any treatment. The model may not work in other hospitals or populations.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Adult patients with clinically and radiologically confirmed non-cystic fibrosis bronchiectasis (NCFB) attending outpatient clinics, inpatient wards, or respiratory follow-up services at Assiut University Hospitals during the enrollment period will be prospectively screened. Eligible participants will undergo baseline disease-signature assessment within the Bronchiectasis Phenotype Identification Model (BPIM) framework and planned longitudinal follow-up for latent class trajectory analysis (LCTA), supervised BPIM classifier development, and validation. Participants receive routine clinical care; no treatment or intervention is assigned by the protocol.

Inclusion Criteria: * Adult patients aged 18 years or older. * Diagnosis of non-cystic fibrosis bronchiectasis (NCFB) based on clinical assessment and high-resolution computed tomography (HRCT). * Patients attending outpatient clinics, inpatient wards, or respiratory follow-up services at Assiut University Hospitals during the study enrollment period. * Patients suitable for baseline disease-signature assessment within the Bronchiectasis Phenotype Identification Model (BPIM) framework. * Ability to undergo routine clinical, functional, radiological, oxygenation, and inflammatory assessment according to the study protocol. * Ability to complete planned longitudinal follow-up required for latent class trajectory analysis (LCTA) and Bronchiectasis Phenotype Identification Model (BPIM) validation. * Written informed consent obtained from the patient or legal representative. Exclusion Criteria: * Cystic fibrosis-related bronchiectasis. * Traction bronchiectasis due to advanced fibrotic interstitial lung disease as the dominant respiratory diagnosis. * Active pulmonary tuberculosis at enrollment. * Active nontuberculous mycobacterial pulmonary disease requiring specific treatment at enrollment. * Active malignancy or terminal non-respiratory illness expected to prevent planned follow-up. * Acute life-threatening illness preventing safe enrollment or reliable baseline assessment. * Recent major thoracic surgery or acute thoracic trauma interfering with baseline respiratory assessment. * Inability to complete required baseline disease-signature assessment according to the Bronchiectasis Phenotype Identification Model (BPIM) protocol. * Inability or unwillingness to complete planned longitudinal follow-up. * Refusal to participate.
