Pleuritis, Non-specificEarly Phase 1PROSPECTNCT07039019
Study of the Feasibility and Efficacy of PrednisonE for Non-specifiC pleuriTis
A Early Phase 1 study testing Corticosteroid and No Corticosteroid in people with Pleuritis, Non-specific, run by Icahn School of Medicine at Mount Sinai at 2 sites in United States.
Trial summary
This research study aims to evaluate whether corticosteroids help prevent the recurrence of pleural effusions in patients with non-specific pleuritis diagnosed through pleural biopsy. It can lead to recurrent fluid buildup in the lungs, causing discomfort and requiring additional medical interventions. Read more about this study

About this study
Official title: Pilot, RandOmized Study of the Feasibility and Efficacy of PrednisonE for Non-specifiC pleuriTis
This research study aims to evaluate whether corticosteroids help prevent the recurrence of pleural effusions in patients with non-specific pleuritis diagnosed through pleural biopsy. It can lead to recurrent fluid buildup in the lungs, causing discomfort and requiring additional medical interventions. There is no established treatment to prevent recurrence, and this study seeks to determine whether steroids reduce fluid buildup or cause complications.
There will be two groups: one receiving corticosteroids (standard of care in the institution) and one not receiving corticosteroids (intervention group). The participation will last approximately 6 months, with in-person visits every 2 weeks for the first month, then monthly, along with possible telephone follow-ups. The study will monitor for pleural effusion recurrence, need for additional procedures, and potential side effects of corticosteroids.
This is a pilot study. Although there are forty people expected to take part in this research study based on institutional data, the number of patients included in the study will be determined by the number of patients with non-specific pleuritis diagnosed during the study period.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
CorticosteroidDrug
Also called Prednisone
Patients take 40 mg of prednisone daily for 4 weeks to help reduce inflammation.
No CorticosteroidOther
Patients do not take corticosteroid.
| Study group | Role | What they receive |
|---|---|---|
| Patients with Corticosteroids | Experimental | Standard of care (corticosteroids) as per institutional practice. If the treatment is effective, patients continue for another 4 weeks while taking medication to prevent infections. If it's not effective, they begin a gradual dose reduction until stopping. Receives: Drug: Corticosteroid |
| Patients with No Corticosteroids | Active comparator | Patients will not receive any corticosteroids. Receives: Other: No Corticosteroid |

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Corticosteroid and No Corticosteroid in people with Pleuritis, Non-specific, run by Icahn School of Medicine at Mount Sinai at 2 sites in United States.
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 1 inclusion and 6 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: looking for participants now, as of the sponsor's last update on 25 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United States. 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. 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?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Axel Duval, MD (212-824-8546, axel.duval@mountsinai.org), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of patients screened (time frame: every 2 weeks after pleuroscopy for the first 4 weeks, and then monthly up to 6 months). The study lists 3 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 25 Jun 2026.
