    An Open-Label Study to Explore the Impact of Inhaled Treprostinil Sodium on Ventilation Perfusion Matching When Used for Treatment of Group 1 Pulmonary Arterial Hypertension in Patients With Concomitant Chronic Obstructive Pulmonary Disease (COPD)

    Location:

    Jacksonville, Fla.

    Trial status:

    Open for Enrollment

    Why is this study being done?

    In patients with severe COPD where the FEV1 is 50% or less than predicted, emphysema and obliterating bronchiolitis presenting a "ceiling" to any improvement in function that can be achieved by therapies that dilate the airways or lessen inflammation. Such severe COPD is commonly associated with pulmonary hypertension at rest or during exercise. Although hypoxia has been classically considered to be the major pathogenic mechanism of pulmonary hypertension in COPD and oxygen has been the mainstay of therapy, other mechanisms may play important roles. Indeed, endothelial dysfunction can be observed in patients with mild to moderate COPD who do not have hypoxemia and in smokers with normal lung function. In addition, long-term oxygen therapy does not generally result in resolution of the pulmonary hypertension. A key question that remains is whether the newer therapies for pulmonary arterial hypertension (PAH) could improve pulmonary hypertension and therefore exercise tolerance in COPD. Unfortunately the use of non-selective pulmonary vasodilator therapy in oral, intravenous or subcutaneous form for PAH patients who have unrelated concomitant COPD, is known to cause worsening gas exchange and intensification of symptoms despite a decrease in pulmonary vascular resistance and arterial pressures. We hypothesize that an inhaled pulmonary vasodilator may not worsen ventilation-perfusion mismatching by selectively vasodilating well ventilated areas in PAH patients with concomitant COPD and in fact may improve ventilation perfusion matching leading to preservation or improvement of oxygenation.

  2. The Systolic Blood Pressure Intervention Trial (SPRINT) is a two-arm, multicenter, randomized clinical trial designed to test whether a treatment program aimed at reducing systolic blood pressure (SBP) to a lower goal than currently recommended will reduce cardiovascular disease (CVD) risk.
    Jacksonville, Fla. View Summary

    The Systolic Blood Pressure Intervention Trial (SPRINT) is a two-arm, multicenter, randomized clinical trial designed to test whether a treatment program aimed at reducing systolic blood pressure (SBP) to a lower goal than currently recommended will reduce cardiovascular disease (CVD) risk.

    Location:

    Jacksonville, Fla.

    Trial status:

    Open for Enrollment

    Why is this study being done?

    Elevated blood pressure (BP) is an important public health concern. It is highly prevalent, the prevalence may be increasing, and it is a risk factor for several adverse health outcomes, especially coronary heart disease, stroke, heart failure, chronic kidney disease, and decline in cognitive function.  SPRINT will randomize about 9250 participants aged ≥ 55 years with SBP ≥130 mm Hg and at least one additional CVD risk factor. The trial will compare the effects of randomization to a treatment program of an intensive SBP goal with randomization to a treatment program of a standard goal. Target SBP goals are <120 vs <140 mm Hg, respectively, to create a minimum mean difference of 10 mm Hg between the two randomized groups. The primary hypothesis is that CVD event rates will be lower in the intensive arm. Participants will be recruited at approximately 90 clinics within 5 clinical center networks (CCNs) over a 2-year period, and will be followed for 4-6 years.

  3. A Multicenter, Double-blind, Randomized, Placebo-controlled, Phase 3 Study to Assess the Efficacy and Safety of Oral BPS-314d-MR added-on to Treprostinil, Inhaled (Tyvaso®) in Subjects With Pulmonary Arterial Hypertension

    A Multicenter, Double-blind, Randomized, Placebo-controlled, Phase 3 Study to Assess the Efficacy and Safety of Oral BPS-314d-MR added-on to Treprostinil, Inhaled (Tyvaso®) in Subjects With Pulmonary Arterial Hypertension

    Location:

    Jacksonville, Fla.

    Trial status:

    Open for Enrollment

    Why is this study being done?

    This is a multicenter, double-blind, randomized, placebo-controlled Phase 3 study, to assess the efficacy and safety of BPS-314d-MR when added-on to inhaled treprostinil (Tyvaso®)in patients with pulmonary arterial hypertension. Patients new to Tyvaso, will enter a run-in period on inhaled treprostinil until 90 days of experience is achieved to ensure drug tolerability before enrolling in the study. Treatment groups consist of one active and one placebo group. Subjects will be randomly allocated in a 1:1 ratio to one of the two treatment groups.
