Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of CT-G20 or CT-G11 and Food Effect of CT-G20 in Human Participants

June 7, 2020 updated by: Celltrion

A Two-segment Phase I, Randomized, Double-Blind, Placebo-Controlled, Sequential, Ascending Single and Multiple Dose Study to Evaluate Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of CT-G11 and CT-G20 in Healthy Volunteers (Part 1 and Part 2) and Open Label, Balanced, Randomized, Two-period, Two-Sequence Crossover Study to Assess the Effect of Food on the Pharmacokinetics of CT-G20 in Healthy Volunteers (Part 3)

The purpose of this study is to establish safety, tolerability, pharmacokinetics and pharmacodynamics of CT-G20 or CT-11 and to evaluate potential effect of food on pharmacokinetics of CT-G20 in human participants. It will be conducted in three parts, as described below:

  • Part I will be a randomized, double-blind, placebo-controlled, sequential, single ascending dose study.
  • Part II will be a randomized, double-blind, placebo-controlled, sequential, multiple ascending dose study.
  • Part III will be a randomized, open-label, balanced, two-period, two-sequence crossover, food effect study.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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

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

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.
72

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

15 years to 51 years (Adult)

Accepts Healthy Volunteers

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

Secondary Outcome Measures

Secondary Outcome Measures
