    Effects of Combination of Bosentan and Sildenafil Versus Sildenafil Monotherapy on Morbidity and Mortality in Symptomatic Patients With Pulmonary Arterial Hypertension - A Multicenter, Double-blind, Randomized, Placebo-controlled, Parallel Group, Prospective, Event Driven Phase IV Study

    Location:

    Jacksonville, Fla., Rochester, Minn.

    Trial status:

    Open for Enrollment

    Why is this study being done?

    This study will investigate the effects of the combination of bosentan and sildenafil. Patients with symptomatic PAH treated with a stable dose of sildenafil equal to or greater tha 20 mg t.i.d. for at least 12 weeks will be randomized to placebo or bosentan 125 mg b.i.d. All randomized patients will be treated with study drug until the predefined target number of morbidity/mortality events is reached.

    Randomized Trial of Rosuvastatin for Acutely Injured Lungs From Sepsis

    Location:

    Rochester, Minn.

    Trial status:

    Open for Enrollment

    Why is this study being done?

    ALI/ARDS involves extensive inflammation in the lungs that can lead to rapid respiratory failure. These conditions are most commonly caused by pneumonia, generalized infection, or severe trauma to the lungs, but can also be less commonly caused by smoke or salt water inhalation, drug overdose, or shock. For some people, ALI/ARDS resolves without treatment, but many severe cases result in hospitalization in the intensive care unit (ICU), where 30% to 40% of cases end in mortality. Current treatments for ALI/ARDS include assisted breathing with a ventilator, supportive care, and management of the underlying causes. Upon admission to the ICU, Rosuvastatin or placebo will be administered through an enteral feeding tube or administered orally following extubation when patients are able to safely take oral medications. The type and placement of the enteral feeding tube (nasogastric, nasoenteric, PEG, orogastric, oroenteric, etc.) and the ability to safely take oral medications will be determined by the patient's primary team. Study drug will be blinded with an identical appearing placebo. The first study drug dose (rosuvastatin or placebo) will be administered within 4 hours of randomization as a loading dose of 40 mg. Blood pressure, heart rate, ventilation settings, and various blood factors will be measured during treatment. Phone-based follow-up assessments will occur at Months 6 and 12 after ICU discharge and will include measurements of health-related quality of life; psychological, neurocognitive, and physical activity outcomes; healthcare utilization; and mortality.
