Single Ascending Dose Study of PCSK-9 Inhibitor (IBI306) in Healthy Subjects.

December 17, 2020 updated by: Innovent Biologics (Suzhou) Co. Ltd.

A Randomized, Double Blind, Dose Escalation Study to Evaluate the Safety, Tolerability and Pharmacokinetics/Pharmacodynamics of IBI306 in Healthy Subjects.

IBI306 is a fully human monoclonal antibody that binds proprotein convertase substilisin/kexin type 9 (PCSK9), preventing its interaction with the low-density lipoprotein cholesterol receptor (LDL-R) and thereby restoring LDL-R recycling and low-density lipoprotein cholesterol（LDL-C）uptake. This is a randomized, double-blind, placebo-controlled,single ascending dose study to evaluate the safety, tolerability, pharmacokinetics/pharmacodynamics and immunogenicity of IBI306 in healthy adults.

Study Overview

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

Ascending dose design includes 6 dose levels （25 mg, 75 mg, 150 mg, 300 mg, 450 mg and 600 mg). Tolerance and safety data up to 14 days after dosing from all subjects of the previous cohort will be reviewed before proceeding to the next dose. Total duration of the study per subject is 12 weeks.

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 55 years (Adult)

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: up to 12 weeks
up to 12 weeks

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
The area under the curve (AUC) of serum concentration of the drug after the administration
