Experimental drug aims to help ARDS patients breathe easier
NCT ID NCT05496868
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This Phase 2 trial tested whether adding reparixin, an anti-inflammatory drug, to standard care could improve lung function in adults with moderate to severe acute respiratory distress syndrome (ARDS). The study enrolled 66 patients on mechanical ventilators. Researchers measured changes in oxygenation and how many days patients were free from the ventilator. The goal was to see if reparixin could speed recovery and reduce inflammation.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Reparixin (an experimental anti-inflammatory drug)
- What this could lead to
- If successful, reparixin could help reduce lung injury and shorten the time patients with ARDS need a ventilator, potentially improving recovery.
- What could go wrong
- This is an early Phase 2 trial with only 66 participants, so results may not apply to all ARDS patients. The drug may not show clear benefit over standard care, and side effects are possible.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Signed Informed Consent, according to local guidelines and regulation. 2. Male and female adults (\>18 years old). 3. Mechanically ventilated (invasive) patients with PaO2/FIO2 ratio ≤200 in the presence of PEEP of ≥5 cmH20. 4. Respiratory failure not fully explained by cardiac failure or fluid overload (if acute Congestive Heart Failure exacerbation is identified as part of the clinical picture this should be addressed effectively and as soon as possible before the patient can be enrolled). 5. Bilateral radiologic opacities consistent with pulmonary edema on the frontal chest x-ray (CXR), or bilateral ground glass opacities on a chest computerized tomography (CT) scan. 6. ≤48 hours from fulfilling above ARDS criteria (if a patient is transferred from a non-participating hospital to a participating site a 12-hour period beyond the 48 hours is allowed) 7. Females of child-bearing potential who are sexually active must be willing not to get pregnant within 30 days after the last Investigational Medicinal Product (IMP) dose and must agree to at least one of the following reliable methods of contraception: 1. Hormonal contraception, systemic, implantable, transdermal, or injectable contraceptives from at least 2 months before the screening visit until 30 days after the last IMP dose; 2. A sterile sexual partner; 3. Abstinence. In patients non able to personally consent to above due to complications of acute illness and/or its treatment assurances for the above must be given by LR and reiterated by patient when/if she is able to do so. Female participants of non-child-bearing potential or in post- menopausal status for at least 1 year will be admitted. For all female subjects with child-bearing potential, pregnancy test result must be negative before first drug intake. Exclusion Criteria: 1. Moderate-Severe chronic hepatic disease (as verified by a previously known Child-Pugh score ≥7). If baseline Child-Pugh score is not known it should not be calculated while the patient is acutely ill. In that case the patient is excluded on the basis of: ALT/AST ≥ 3x ULN and total bilirubin \> 2x ULN or ALT/AST ≥ 5x ULN 2. Severe chronic renal dysfunction: eGFR (2021 CKD-EPI) \< 30 mL/min/1.73m2. If baseline (chronic) renal function is not known the patient is only excluded if in need of acute renal replacement therapy (currently on RRT or to be imminently placed on RRT) 3. Participation in another interventional clinical trial. 4. Patients that are clinically determined to have a high likelihood of death within the next 24 hours based on PI's estimation. 5. Currently receiving ECMO or high frequency oscillatory ventilation. 6. Anticipated extubation within 24 hours of screening. (In such cases re-screening is allowed if the patient is within the enrollment window). 7. Evidence of GI dysmotility as demonstrated by presence of all the following: persistent gastric distention and enteral feeding intolerability and persistent gastric residuals \>500 ml). 8. Anticipated transfer to a hospital not participating in the trial within 72 hours of screening. 9. Decision to withhold or withdraw life-sustaining treatment (patients may still be eligible however if they are committed to full support except cardiopulmonary resuscitation if cardiac arrest occurs). 10. History of: 1. Documented allergy/hypersensitivity to sulfonamides, ibuprofen and other COX-1 and 2 inhibitors, and to the study product and/or its excipients. 2. Lactase deficiency, galactosemia or glucose-galactose malabsorption. 3. History of peptic ulcer, GI bleeding or perforation due to previous NSAID therapy. 11. Active bleeding (excluding menses) from uncontrolled site that cannot be definitively resolved prior to enrollment. 12. Pregnant or lactating women. 13. Women of childbearing potential and fertile men who do not agree to use at least one primary form of contraception during the study and up to 30 days after the last IMP dose. For patients non able to personally consent to above due to complications of acute illness and/or its treatment assurances for the above must be given by LR and reiterated by patient when/if he/she is able to do so.
