Efgartigimod Co-administered Subcutaneously With rHuPH20 in Healthy Subjects

December 27, 2019 updated by: argenx

A Phase 1, Randomized, Open-label, Parallel-group Trial to Investigate the Pharmacodynamics, Pharmacokinetics, Safety, and Tolerability of Different Single Subcutaneous Dose Levels of Efgartigimod Co-administered With rHuPH20 in Healthy Adult Male Subjects

The aim of this trial is to investigate the pharmacodynamic (PD), pharmacokinetic (PK), safety, tolerability, and immunogenicity of efgartigimod co-administered with rHuPH20, and to measure the time to inject the full dose of investigational medicinal product (IMP) of different dose levels of efgartigimod co-administered with a fixed concentration of rHuPH20 by the subcutaneous (SC) route of administration in healthy adult male subjects.

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.

Study Type

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

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

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
Time Frame
IgG levels of four different subcutaneous dose levels
Time Frame: Up to 11 weeks, from study start until the end of the study
Up to 11 weeks, from study start until the end of the study

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
Maximum serum concentrations (Cmax) of four different subcutaneous dose levels of efgartigimod co-administered with rHuPH20
Time Frame: Up to 11 weeks, from study start until the end of the study
