Clinical Trials for Tyvaso

Trial ID Title Status Sponsor Phase Start Date Summary
NCT00147199 Clinical Investigation Into Inhaled Treprostinil Sodium in Patients With Severe Pulmonary Arterial Hypertension (PAH) Completed United Therapeutics Phase 3 2005-06-01 This is a double-blind placebo-controlled clinical investigation into the efficacy and tolerability of inhaled treprostinil in patients with severe pulmonary arterial hypertension. The primary outcome is the change in 6-minute walk distance from baseline to week 12.
NCT00741819 Safety Evaluation of Inhaled Treprostinil Administration Following Transition From Inhaled Ventavis in Pulmonary Arterial Hypertension (PAH) Subjects Completed United Therapeutics Phase 4 2008-09-01 This is a 24-month, multi-center, prospective, open-label, safety evaluation in PAH subjects following transition from a stable dose of inhaled iloprost (Ventavis). Subjects are to be evaluated for safety throughout the course of the study while secondary assessments will be conducted at Baseline, Week 6, Week 12, and Months 6, 12, 18 and 24 following initiation of treprostinil sodium.
NCT01266265 Study of Incidence of Respiratory Tract AEs in Patients Treated With Tyvaso® Compared to Other FDA Approved PAH Therapies Completed United Therapeutics N/A 2010-12-01 A surveillance of respiratory tract related adverse events in patients treated with Tyvaso®(treprostinil) Inhalation Solution versus other FDA approved therapies
NCT01268553 Transition From Injectable Prostacyclin Medication to Inhaled Prostacyclin Medication Active, not recruiting United Therapeutics Phase 4 2010-08-01 The purpose of this study is to assess tolerability and clinical effects of transition from intravenous (IV, needle in the vein) or subcutaneous (SQ, needle in the skin) to the recently-approved inhaled treprostinil (Tyvaso) for the treatment of pulmonary arterial hypertension (PAH). Our hypothesis is that the transition to inhaled treprostinil will be tolerated by patients. The intravenous and subcutaneous drugs epoprostenol and treprostinil received approval for treatment of PAH many years ago. While these medications improve exercise capacity and the symptoms of PAH, they are given by injection and thus have several side effects, such as pain and catheter infection. This has resulted in many patients either refusing to take the medication or quitting these medications because of not tolerating them. The only other form of prostacyclin treatment available for PAH patients is inhaled. There are 2 inhaled prostacyclins approved for PAH, however one of these requires at least 6 inhalations per day, every day, and takes about 30 minutes to inhale each time. Thus, it has not been a regularly-used medication and issues surrounding compliance make it a riskier drug to use if patients do not get their full doses every day. The other inhaled medication, treprostinil, was approved a few months ago, only needs to be given 4 times a day, and takes about 2-3 minutes to inhale. Since inhaled treprostinil can be administered easily, it is anticipated that many patients will transition from epoprostenol or treprostinil to the recently approved inhaled treprostinil, however we do not know if this is a safe or effective way to manage patients. Thus, the goal of this prospective study is to gather observational data regarding how that switch is made, tolerability of the switch, and, to the extent possible with this methodology, assess clinical effects of the switch. This is a prospective study. Twenty patients > 18 years old with PAH will be enrolled. Patients enrolled will be those in whom a clinical decision to convert from either IV epoprostenol, IV treprostinil, or SQ treprostinil to inhaled treprostinil therapy has been made. This is usually the result of patients asking to switch to inhaled therapy, but only allowed by physicians if they feel the switch would be safe. If eligible, and after informed consent, patients will have a history and physical examination, a 6 min walk test, a cardiopulmonary exercise test (CPET), blood tests, and a symptom questionnaire will be filled out. Patients will then be admitted to the hospital where a monitoring catheter will be placed inside the patient's heart and inhaled treprostinil will be initiated, while the dose of IV/SQ medication is reduced over about 24-26 hours. Clinical follow-up will be at weeks 1, 4, and 12. The procedures above are all part of the routine clinical care that patients would receive if they were to be transitioned to inhaled therapy, including the hospitalization and catheterization. The criteria for them to be able to be switched are conservative. Pressure in their heart and lungs must be low (mPAP < 40 mmHg and RAP <12 mmHg on catheterization), and their dose of IV or SQ medication must be low (< 20 ng/kg/min). Regarding the patient subset enrolled in this study in whom a clinical decision to convert transition therapy has been made, we will try to ensure that our clinical decision-making will not be influenced by the need to enroll subjects in the study by explicitly noting the potential for conflict of interest with each patient (addressed in the ICF). We will not make a clinical decision for our patients based on the desire to fill the study numbers, and every will be made to avoid the potential for a perceived conflict of interest.
