A Randomized Controlled Trial of Inhaled Tranexamic Acid for the Treatment of Pulmonary Hemorrhage in Cancer Patients

This study tests whether inhaled tranexamic acid (a drug that helps stop bleeding, delivered as a fine mist through a breathing tube) can reduce or stop bleeding in the lungs of cancer patients who are on ventilators (breathing machines). Lung bleeding is a life-threatening complication in some blood cancer patients. **You may be eligible if...** - You are 18 or older with a diagnosed blood cancer (like leukemia or lymphoma) - You are currently on a mechanical ventilator - You have confirmed bleeding in the lungs (bloody secretions or confirmed by bronchoscopy) - You or your legal representative can give consent **You may NOT be eligible if...** - You are not expected to survive more than 48 hours - You have a do-not-resuscitate or comfort-care order in place - Bleeding appears to be coming from the nose or mouth rather than the lungs - You have a known clotting condition that increases stroke risk Talk to your doctor to see if this trial is right for you.
