Evaluation the Pharmacokinetics, Safety, Tolerability of TK001 in Patients With Neovascular Age-related Macular Degeneration

February 27, 2018 updated by: Jiangsu T-Mab Biopharma Co.,Ltd

A Single-center, Open-label, Single Ascending Dose Phase 1 Study to Evaluate the Safety, Pharmacokinetics, and Tolerability of Intravitreal TK001(Recombinant Humanized Anti-VEGF Monoclonal Antibody) in Subjects With Neovascular Age-Related Macular Degeneration

The purpose of this first-in-human study is to evaluate the safety, pharmacokinetics and tolerability of single ascending doses of TK001(Recombinant humanized anti-VEGF monoclonal antibody) to determine the maximum tolerated dose (MTD) in neovascular wet age-related macular degeneration (wAMD) subjects.

Study Overview

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 an open-label, non-comparative, non-randomized, single-center phase 1 study evaluating pharmacokinetics, safety and tolerability of single intravitreal injections of TK001 in the patients with AMD.TK001 is a full-length recombinant humanized anti-VEGF monoclonal antibody. Compared with Avastin(a similar marketed product), the findings of preclinical studies suggested that TK001 might be more effective in inhibiting pathological angiogenesis, or to achieve equivalent effect with less dosage and better safety. In this study, participants will be administrated a single dose of TK001.Every subject will only accept one dose. In addition to safety and preliminary efficacy, pharmacokinetics and immunogenicity of TK001will be evaluated as well.

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.

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.
