Raising the Bars in the Treatment of Pulmonary Arterial Hypertension: Goal Oriented Strategy to Preserve Ejection Fraction Trial

In this prospective long term feasibility study we examine whether a goal oriented therapeutic strategy that is able to preserve right ventricular function will result in improved clinical outcome in patients with pulmonary arterial hypertension. We hypothesize that right ventricular function can only be preserved when early and aggressive medical combination therapy not only reduces pulmonary vascular resistance but also pulmonary pressures.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Rationale:

The current strategy in patients with pulmonary arterial hypertension (PAH)is to improve exercise capacity which can be achieved by decreasing pulmonary vascular resistance (PVR) and subsequently increasing cardiac output (CO). Despite this load reduction, a substantial proportion of patients show progressive right ventricular (RV) dysfunction leading to clinical worsening and death. A possible explanation is that current therapies show a relatively modest reduction in PVR, leaving mean pulmonary artery pressure (mPAP) unchanged. As a consequence RV work, defined as the product of CO and mPAP increases, contributing to progressive RV dysfunction.

Hypothesis:

A goal oriented therapeutic strategy that is able to preserve RV function will result in improved clinical outcome. RV function can only be preserved when early and aggressive combination therapy not only reduces PVR but also mPAP.

Study questions:

  1. Will a goal oriented strategy to preserve/improve RV function, measured by right ventricular ejection fraction (RVEF) be effective?
  2. Does early and aggressive combination therapy result in improved RV function and survival during long term follow-up?
  3. Does a strategy to preserve RVEF also translate into improvements of other clinically meaningful parameters?
  4. Can RVEF be replaced by more simple measures?
  5. Will a goal oriented strategy to improve RVEF also lead to improvement of myocardial performances and coupling of the RV to its load?

Study design and study population:

In this prospective longitudinal feasibility study, thirty newly diagnosed idiopathic or heritable PAH patients with New York Heart Association (NYHA) functional class II or III will be included. Maintenance/improvement of RVEF will be our primary outcome parameter and therefore cardiac magnetic resonance imaging (CMR) will be performed at baseline and at 4, 8 , 12 and 24 months of follow-up. Six-minute walk testing (6MWT), quality of life questionnaires and blood sampling (NT-proBNP) will be performed at similar follow-up intervals. In addition, right heart catheterization (RHC) will be performed at baseline, after 4, 12 and 24 months of follow-up.

NYHA II patients will start with single agent medical treatment whereas patients with NYHA III will start on combination therapy (2 treatments). In case of a stable/improved RVEF during each follow-up measurement (defined as no decrease in RVEF >3% compared to previous measurement), the treatment strategy will remain unchanged. In case of decreased RVEF >3%, additional medical therapy will be added. Our hypothesis will prove to be correct when the additional medical treatment result in improved RVEF during the subsequent follow-up measurement.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
