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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study tests a new, non-invasive device that uses a special light to quickly identify a hard-to-treat type of nasal polyp called eosinophilic CRSwNP. Currently, diagnosing this subtype requires surgery to take a tissue sample, which can delay treatment. The device shines a safe light on the polyp during a clinic visit and analyzes the glow to give a diagnosis in real time. Researchers will enroll 353 adults with nasal polyps to see how accurate and safe the system is compared to standard lab tests.

What this could mean

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

Active substance
High-sensitivity spectroscopy with autofluorescence diagnostic system
What this could lead to
If successful, this could allow doctors to diagnose a hard-to-treat subtype of nasal polyps before surgery, leading to more personalized treatment and fewer unnecessary operations.
What could go wrong
This is an early-stage diagnostic study, not a treatment trial. The system may not be accurate enough in real-world use, and it only helps with diagnosis, not with curing the condition.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Male and female subjects aged 18 to 65 years old 2. Subjects diagnosed with CRSwNP by nasal endoscopy, CT, or MRI preoperatively (in accordance with the diagnostic criteria of EPOS 2020) 3. Normal coagulation function (prothrombin time \[PT\], activated partial thromboplastin time \[APTT\], and platelet count are within the normal range) 4. No severe cardiopulmonary dysfunction or other comorbidities that affect the tolerance of general anesthesia and surgery 5. Women of childbearing age must take appropriate medical contraceptive measures during the study period and within 4 weeks after the end of the trial treatment 6. Patients with good compliance, who voluntarily participate in this clinical study and sign the informed consent form. Exclusion Criteria: 1. Patients with other nasal and paranasal sinus diseases excluding chronic rhinosinusitis (such as nasal tumors, fungal sinusitis, and post-traumatic nasal deformities) 2. Patients with coagulation dysfunction, immunodeficiency, or long-term use of anticoagulant/antiplatelet drugs at the time of visit, and females during menstruation 3. Patients who have taken oral glucocorticoids within 1 month prior to the visit 4. Patients with a history of nasal endoscopic surgery or nasal radiotherapy 5. Pregnant or lactating women, or those with severe systemic diseases (such as uncontrolled hypertension, diabetes, hepatic or renal insufficiency) 6. Patients with incomplete clinical data or missing postoperative follow-up data 7. Any other conditions deemed by the researcher as making the subject unsuitable for participating in the trial 8. Patients with poor treatment compliance
