A Phase 2a Study of Weekly Doses of GCS-100 in Patients With Chronic Kidney Disease

August 31, 2015 updated by: La Jolla Pharmaceutical Company

A Phase 2a, Placebo-Controlled, Randomized, Single-Blind Study of Weekly Doses of GCS-100 in Patients With Chronic Kidney Disease

The primary objective of this study is to compare the change in estimated glomerular filtration rate (eGFR) from baseline to Week 8 between placebo and GCS-100 treatment. The secondary objective is to determine the safety and tolerability of GCS-100 administered for 8 weeks relative to placebo. In addition, the study will measure the effect of GCS-100 on circulating galectin-3 and other markers of disease activity.

Study Overview

Status

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

Galectin-3 contributes to fibrosis, is elevated in patients with ESRD, and correlates with adverse outcomes (de Boer et. al., 2011, Dang et. al., 2012, Fernandes Bertocchi et. al., 2008, Henderson et. al., 2008). Animal models with genetic knockout of galectin-3 demonstrate a reduction in structural and functional deficits in the kidney (Dang et. al., 2012, Fernandes Bertocchi et. al., 2008, Henderson et. al., 2008). GCS-100 is a galectin- 3 antagonist that has been shown to reduce fibrosis pre-clinically. Based on the role of galectin-3 and fibrosis in kidney disease, the Sponsor believes GCS-100 may be effective at treating patients with CKD.

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.

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

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 80 years (Adult, Older Adult)
