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 study that will be conducted at a single site in Argentina to characterize the Pharmacokinetics (PK) profile, safety and tolerability of anti-Shiga toxin hyperimmune equine immunoglobulin F(ab')2 fragment (INM004) in 14 healthy subjects. This is a dose escalation study. Subjects will receive a single dose of an infusion of the biological product or placebo in Stage I where 2 cohorts will be assessed with 2 different doses of INM004. Subjects will receive a repeated dose (3 doses total, every 24 hs) of an infusion of the biological product or placebo in Stage II. The total duration of study participation is 4 weeks for each subject. Subjects will complete a follow-up visit at Day 30 after the dosing. Study duration is expected to last 6 months. The investigational product intent to use is for the prevention of the development of Hemolytic Uremic Syndrome (HUS) associated to Shigatoxin producing Escherichia coli (STEC).

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.
