A Study Designed to Compare the Safety and Pharmacokinetics of Intravenously Administered Superoxide Dismutase Mimetic GC4711 and GC4419 in Healthy Volunteers

February 13, 2018 updated by: Galera Therapeutics, Inc.

A Phase 1, Randomized, Double-Blind, Crossover, Single Dose Study Designed to Compare the Safety and Pharmacokinetics of Intravenously Administered Superoxide Dismutase Mimetic GC4711 and GC4419 in Healthy Volunteers

The study will be a double-blind, randomized, crossover, single-dose assessment of IV-administered GC4711 compared to GC4419 in healthy volunteers.

Consenting subjects will undergo screening procedures within 28 days of the start of dosing. Pharmacokinetics (parent drug and major metabolites) will be assessed in plasma and urine from all subjects.

Initially, a sentinel cohort of 4 subjects, will be enrolled; each eligible subject will receive single dose of GC4711 IV at dose of 30 mg over one hour. Following a clinical safety review by the Galera study team , if no safety concerns are identified after the last subject completes study participation, enrollment will continue in 2 stages to a crossover study design. In stage 1, 12 subjects will be enrolled and in stage 2, if no safety concerns are identified in stage 1 following a clinical safety review by the Galera study team, 20 subjects will be enrolled. In both enrollment stages, eligible subjects in the crossover design will be randomized in 1:1 ratio to one of two treatment sequences: Test (GC4711) -> Ref (GC4419) or Ref (GC4419) -> Test (GC4711). On Day 1, subjects will receive the first treatment they were randomized to, and on Day 4 (following a washout), they will receive the second treatment. Subjects will be followed up for 2 days after the second treatment.

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

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 50 years (Adult)

Accepts Healthy Volunteers
