July 12, 2018 updated by: Windtree Therapeutics

A Multicenter, Randomized, Controlled Trial Comparing the Safety and Effectiveness of SURFAXIN® (Lucinactant) Delivered Via Bronchopulmonary Segmental Lavage to Standard of Care in Patients With Acute Respiratory Distress Syndrome (ARDS).

Lung wash with KL₄Surfactant of individual lung segments using a bronchoscope compared to usual care alone consisting primarily of assisted (mechanical) ventilation in patients with acute respiratory distress syndrome(ARDS).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

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

This is a multinational, multicenter, two-part, Phase 2 study that will evaluate the tolerability, safety, and efficacy of KL₄Surfactant in adult ARDS patients when administered by sequential bronchoscopic lavage into each of the 19 bronchopulmonary segments of the lung and as a bolus instillation into each lung.

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

16 years to 75 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Intubated and required mechanical ventilation support
  • Met the criteria for ARDS
  • Partial pressure of oxygen/fraction of inspired oxygen (PaO2/FiO2) ≤ 200 mmHg and ≥ 60 mmHg within 60 minutes before randomization
  • Mean blood pressure was ≥ 60 mmHg immediately before randomization

Exclusion Criteria:

  • Had ARDS due solely to a major trauma
  • Was currently participating in another clinical trial or received an experimental drug or device within the previous month

  • Had a disease that was sufficiently advanced, in the best judgment of the Principal Investigator, to markedly limit life expectancy to < 6 months

What is the study measuring?
