November 22, 2015 updated by: Xu Zhuoming, Shanghai Jiao Tong University School of Medicine

Randomized Double-blind Study of Inhaled Iloprost for the Treatment of Pulmonary Hypertension (PH) and Pulmonary Hypertensive Crisis (PHC) After Repair of Congenital Heart Disease (CHD)

The aim of this study is to determine whether inhaled iloprost can be used to prevent and treat PH and PHC while in children after operation of CHD

Study Overview

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

Pulmonary hypertension (PH) is a significant contributor to the postoperative morbidity and mortality of congenital heart disease. Inhaled iloprost has been approved for the treatment of adults with PH, but little is known about the effects in children with PH.

Iloprost is a prostacyclin analogue. When applied by inhalation, it selectively dilates pulmonary vessels without side affecting the systemic circulation. There is no RCTs of iloprost have previously been performed in this indication.

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.

Ages Eligible for Study

1 week to 12 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

  2. EKG: right ventricular hypertrophy, right atrial dilatation
  3. Chest X-ray: enhanced vascular signs in trans-hilar, loss of blood vessal in bilateral lung fields, pulmonary arterial trunk dilatation, right ventricular enlargement
  4. Cardiac echocardiography: fast tricuspid or pulmonary valve regurgitant velocity, ventricular and aortic level bidirectional shunt, or even right-to-left shunt
  5. Under-filling of pulmonary capillary, 'pruning' of the peripheral blood vessels

  9. Rp/Rs graeter than 0.5

Exclusion Criteria:

After corrective procedure for CHD:

  1. Deficient anatomy associated with remained intracardiac shunts and severe artrio-ventricular regurgitation
  2. Severe arrhythmia led to low cardiac output
  3. PLT smaller than 50,000*109/L and obvious bleeding

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The primary end point is a composite variable (incidence rate of any events) consisting of reactive PH, PHC and death requiring additional pharmacological or other support administered within the first 48 hours after receiving study drug.
Time Frame: The pulmonary heamodynamic variable is measured before, after ilkoprost inhalation instantly and 30-min later.

Reactive PH is defined as Pp/Ps greater than 0.5 for more than 30min.

End point of observation: in case of Pp/Ps greater than 0.5 for more than 30min or Pp/Ps greater than 1 for any time period, drug inhalation will be immediately stopped and other therapies such as NO inhalation and/or iloprost 80 ng/kg/min inhalation will be resorted to treat pulmonary hypertension.
The pulmonary heamodynamic variable is measured before, after ilkoprost inhalation instantly and 30-min later.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Change from base line of pulmonary heamodynamic measurements: Pp/Ps, PVRI, SVRI
Time Frame: The heamodynamic variable is measured before, after iloprost inhalation instantly and 30-min later.
The heamodynamic variable is measured before, after iloprost inhalation instantly and 30-min later.
