LB1148 for Pulmonary Dysfunction Associated With COVID-19 Pneumonia

May 9, 2022 updated by: Leading BioSciences, Inc

A Phase 2 Study to Evaluate LB1148 for the Treatment of Pulmonary Dysfunction Associated With COVID-19 Pneumonia

This is a Phase 2, proof of concept, randomized, placebo-controlled, multicenter study to evaluate the ability of LB1148 to attenuate pulmonary dysfunction associated with COVID-19 pneumonia. The primary objective of this study is to determine if enteral administration of LB1148 will effect disease progression in hospitalized patients with moderate to severe COVID-19 via measurement of the proportion of subjects alive and free of respiratory failure at Day 28.

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

The purpose of this study is to establish the safety and tolerability, along with preliminary evidence of efficacy, of LB1148 compared to placebo in hospitalized patients with moderate to severe coronavirus disease (COVID-19). All patients will be randomized into one of two treatment groups (LB1148 or Placebo) in a 1:1 ratio, and stratified by peripheral capillary oxygen saturation (SpO2) ≥ 93% on room air vs. < 93% on room air, and by PF ratio (PaO2, arterial oxygen partial pressure, to FiO2, fractional inspired oxygen) of ≥ 300 mmHg vs. PF ratio of < 300 mmHg at the time of Screening. (If PaO2 cannot be measured or acquired, SpO2 may be substituted to calculate the PF ratio.) LB1148 contains 7.5 g tranexamic acid (TXA), polyethylene glycol (PEG), glucose, and electrolytes. A total of 700 mL of LB1148 will be administered enterally, as a split dose (350 mL, every 12 hours). Study drug is given as a single bolus, to be delivered orally or via nasogastric (NG) or orogastric (OG) tube. For those patients assigned to placebo, a total of 700 mL of placebo will be administered enterally, as a split dose (350 mL, every 12 hours). The placebo contains PEG, glucose, and electrolytes.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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.
