NCT03132428
Pulmonary hypertension is high blood pressure in the arteries to the lungs. It is a serious condition. It causes the blood vessels that carry blood from the heart to the lungs to become hard and narrow. When this happens, the heart has to work harder to pump the blood through. Some babies are born with pulmonary hypertension (PH). Doctors might use INOmax (a gas the baby breathes) to help newborn babies (neonates) with PH. This study will use information from the records of registered babies to see how effective and safe INOmax is for treating premature and other newborn babies for up to 11 days after they are born.
NCT00673790
This study is being done to see if the blood pressure and metabolic effects of an approved drug nebivolol is comparable to that of another approved drug hydrochlorothiazide (HCTZ) and placebo in hypertensive patients.
NCT02553720
The purpose of this study is to test whether addition of aquatic exercise to conventional treatment helps reduce the adverse outcomes of chronic venous insufficiency including CVI resulting from venous thrombosis.

NCT00644605
To evaluate the effect of three doses of oral sildenafil (20, 40 and 80 mg three times a day \[TID\]) on exercise capacity, as measured by the 6-Minute Walk test, as well as the safety and tolerability, after 12 weeks of treatment in subjects with pulmonary arterial hypertension who are aged 18 years and over. To investigate the plasma concentration-effect relationship and to determine the population pharmacokinetic (PK) parameters.
NCT02462967
Study GT 026 is a Phase 2, multicenter, parallel group, North American, randomized, placebo controlled, double blind study. This study will enroll subjects with portal hypertension (HVPG greater than or equal to 6 mm Hg) who also have a liver biopsy with cirrhosis (Ishak stage 5 or 6), presumably due to NASH, excluding subjects with medium and large varices and those with decompensated cirrhosis. Subjects with portal hypertension and cirrhosis will be randomly assigned (1:1:1 ratio) to receive 1 of 3 treatment assignments including placebo, GR MD 02 in a dose of 2 mg/kg lean body mass, or GR MD 02 in a dose of 8 mg/kg lean body mass administered every other week over a 52 week period for a total of 26 intravenous infusions. The primary endpoint analysis is the baseline adjusted change in HVPG at 1 year (53 55 weeks) in subjects treated with placebo as compared to subjects treated with GR MD 02 (2 mg/kg/week or 8 mg/kg/week). An esophagogastroduodenoscopy (EGD) with evaluation for varices, HVPG, and liver biopsy will be performed before the first infusion and after the final 26th dose of the investigational medicinal product (IMP). Additionally, subjects will undergo a FibroScan (if available) prior to the first infusion, at Infusion Visit 13, and 14 to 28 days following final 26th infusion, an methacetin breath test (MBT), will be performed if available at screening, at Infusion Visit 13, and 14 to 28 days after the final infusion, and blood will be collected for assessment of biomarkers. All subjects are to attend 2 postdose visits: the first will occur 14 to 28 days after the final dose administration and a second will occur 14 days following the first postdose visit. Subjects will be offered enrollment into a subsequent separate study, an open label extension study, if there is adequate tolerability and no safety issues or signs of clinical progression that would recommend discontinuation. Subjects who do not enroll in the open label extension study will be contacted via telephone every 6 months for 2 years and annually thereafter for a total of 4 years.
NCT03767803
Whole blood sample procurement study from pregnant women with signs and symptoms of Preeclampsia.
NCT01224210
This is an Open Label, Multicenter, pilot clinical trial to assess the efficacy and safety of an oral selective Endothelin Receptor Antagonist (ambrisentan) in patients with portopulmonary hypertension. Preliminary evidence suggests that ambrisentan is safe and effective in patients with portopulmonary hypertension. The goal of therapy for these patients is to improve symptoms of dyspnea and to improve pulmonary hemodynamics to a mean pulmonary artery pressure \<35 mm Hg in order to make patients eligible for liver transplantation. Therefore, the primary endpoints for this study will include 6 minute walk distance (6MWD) and pulmonary vascular resistance (PVR). Eligible subjects will receive 5 mg ambrisentan once-daily for the first 4 weeks. After the initial 4-week period, investigators will increase study drug dose to 10 mg once daily (both 5 mg and 10 mg doses are FDA approved). If 10 mg is not tolerated in the opinion of investigator, then the investigator may decrease the dose back to 5 mg once daily. Primary outcome is a change in both the 6 Minute Walk Distance and in Pulmonary Vascular Resistance from baseline to Week 24. Subjects will be monitored with liver function tests (LFT) every 2 weeks for the first 8 weeks, then every 4 weeks thereafter. These safety laboratory tests may be performed at a local phlebotomy laboratory or at the Investigator clinic. In addition, the Investigator will assess each subject for safety and efficacy at Week 4, Week 12, and Week 24. Following Week 24, subjects will be assessed for safety and efficacy every 12 weeks. Patients will be followed for a total of 1 year. After 1 year, if the Investigator feels that continuing the treatment will be beneficial to the patients, they will be provided with ambrisentan by Gilead Pharmaceuticals, free of charge.
NCT03808688
To evaluate the IOP lowering efficacy of netarsudil ophthalmic solution 0.02% when used as monotherapy or when used concomitantly with other IOP-lowering agents in subjects with elevated IOP due to open angle glaucoma or ocular hypertension in a real-world clinical setting. The study is an open-label design. The patients will receive treatment for 12 weeks.
NCT02358369
The Bimatoprost Ocular Insert is intended to provide sustained delivery of bimatoprost to the ocular surface to lower the intraocular pressure (IOP) in patients with Open-Angle Glaucoma or Ocular Hypertension. This study evaluated the safety and efficacy of two different doses of the Bimatoprost Ocular Insert, compared to an active control arm with timolol ophthalmic solution (0.5%).
NCT00133679
The purpose of this study is to test if sildenafil is effective in the treatment of infants with severe congenital diaphragmatic hernia (determined by the presence of prolonged pulmonary hypertension or prolonged oxygen supplementation on mechanical ventilation), as measured by the estimated pulmonary artery systolic pressure following treatment.
NCT00147615
To assess the long-term safety and toleration of eplerenone in the children aged 6 to 16 years with high blood pressure. The study will last at least 1 year and about 140 patients will participate.
NCT03858894
This is a randomized, double-masked, parallel-group, multi-center study. Subjects diagnosed with POAG or OHT who meet eligibility criteria at Visit 1 (Screening) will wash out their current topical IOP lowering medication(s), if any. After completing the required washout period, subjects will return for Visit 2 (Baseline, Day 1). Subjects who meet all eligibility criteria at Visit 2 (Baseline, Day 1) will be randomized to receive study medication for up to 6 weeks. Approximately 100 subjects with POAG or OHT will be randomized in a 1:1 ratio to either: * DE-117 ophthalmic solution 0.002% QD (Once Daily) * DE-117 ophthalmic solution 0.002% BID (Twice Daily) This study will consist of a screening period of up to 35 days including a washout period of up to 28 days (+ 7 days window), and a 6-week double-masked treatment period.
NCT02279160
The study was conducted as a placebo-controlled, randomized, 22-week double-blind study which included a dose titration period. An additional transition period occurred for those patients who elected to enroll into the open-label extension study, APD811-007. A total of 61 patients with PAH were enrolled.
NCT02341664
The purpose of the Patient and Provider Assessment of Lipid Management Registry (PALM) is to gain a better understanding of physicians' cholesterol medication prescribing practices, patient and physician attitudes and beliefs related to cholesterol management, and current utilization of cholesterol-lowering therapies given the new ACC/AHA guideline recommendations. The PALM Registry hopes to allow for the design of ways to improve cholesterol management and decrease the burden of cardiovascular disease (CVD) in the US.
