Prevention of Severe SARS-CoV-2 Infection in Hospitalized Patients With COVID-19

February 15, 2024 updated by: Pharming Technologies B.V.

Recombinant Human C1 Esterase Inhibitor (Ruconest®) in the Prevention of Severe SARS-CoV-2 Infection in Hospitalized Patients With COVID-19: a Randomized, Parallel-group, Open-label, Multi-center Pilot Trial in the US

The primary purpose of this study is to evaluate if adding rhC1-INH to standard of care (SOC) in patients admitted for stage II COVID-19 infection may reduce the risk of disease progression, i.e. ALI requiring mechanical ventilation, or increase the chance of a faster clinical improvement compared to SOC alone.

Study Overview

Status

Status

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

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

Patients fulfilling all eligibility criteria will be randomized in a 2:1 ratio in an open-label controlled design to treatment with rhC1-INH in addition to SOC or SOC only starting on day 0. The first rhC1-INH treatment will be administered on the same day and continued for a total of 4 days.

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.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

14 years to 81 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

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
Number of Participants With Each Score on WHO 7-point Outcome Scale at Day 7
Time Frame: Assessed on each day after enrollment (worst status) with the use of the WHO Ordinal Scale and the score on day 7 will be analyzed stratified by its baseline value
The disease severity on the 7-point WHO Ordinal Scale on Day 7 was the primary objective of this study. This endpoint had been suggested by the WHO for clinical trials in patients with Covid-19. The ordinal scale measures illness severity over time. The higher score, the worst outcome: meaning score 1, no limitation in activities and score 7, death.
Assessed on each day after enrollment (worst status) with the use of the WHO Ordinal Scale and the score on day 7 will be analyzed stratified by its baseline value

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
Measure Description
Time Frame
Time to Clinical Improvement
Time Frame: Daily until day 14
Time from randomization to an improvement of (at least) two (score) points on the seven-category WHO Ordinal Scale or live discharge from hospital whichever came first within 14 days after enrollment
Daily until day 14
Invasive (Mechanical) or Non-invasive Ventilation
Time Frame: Daily until day 14.
Admission to ICU with invasive or non-invasive ventilation will be assessed.
Daily until day 14.
Number of Days Hospitalized
Time Frame: between D0 and D90
Amount of days the patient is hospitalized during participation in the study.
between D0 and D90
