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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Age ≥18 years, regardless of gender;
  2. Diagnosed with non-infectious intermediate-, posterior-, or pan-uveitis, and had a medical history of more than 1 yearsince the initial diagnosis;
  3. Must have active disease at the baseline visit while receiving a stable dose of oral prednisone maintenance therapy for at least 2 weeks;
  4. Must have demonstrated a prior adequate response to oral corticosteroid therapy (equivalent of oral prednisone up to 1 mg/kg/day), as judged by the investigator;
  5. No intention to become pregnant and willingness to use highly effective contraception during the study and for 24 weeks after the last dose of study drug;
  6. Able to understand the study procedures, voluntarily agree to participate, provide written informed consent (ICF), and comply with study requirements and complete the study.

Exclusion Criteria:

  1. Subjects with isolated anterior uveitis;
  2. Subjects with neovascular/wet age-related macular degeneration, proliferative or severe non-proliferative diabetic retinopathy, or clinically significant macular edema due to diabetic retinopathy;
  3. Subjects with systemic inflammatory diseases requiring continued treatment with oral corticosteroids or prohibited immunosuppressive agents at screening or baseline visits;

  4. Any of the following:

    Confirmed active tuberculosis (TB) infection, including but not limited to radiologically confirmed active TB; Subjects with latent TB infection or at high risk for TB may be enrolled, provided they are not considered unsuitable by the investigator (e.g., unwillingness to continue anti-TB treatment per local guidelines after entering the study);

  5. Presence of significant comorbidities, including but not limited to: uncontrolled hypertension (≥200/105 mmHg), congestive heart failure (Stage D), or uncontrolled type 1 or type 2 diabetes (fasting blood glucose >7.0 mmol/L or random blood glucose >11.1 mmol/L); eligibility will be determined at the discretion of the investigator;
  6. Subject has previous exposure to anti-tumor necrosis factor (TNF) therapy or any other biologic therapy with a potential therapeutic impact on non-infectious uveitis (intravitreal anti-VEGF therapy excluded) within 12 weeks prior to baseline visit;

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
Measure Description
Time Frame
The effectiveness of GenSci048 administered by subcutaneous injection
Time Frame: 25 weeks
Calculate the proportion of subjects with treatment failure at Week 25 for each GenSci048 dose group and the placebo group, respectively. A superiority test (α=0.05, two-tailed) for the proportion of subjects with treatment failure at Week 25 between each GenSci048 dose group and the placebo group is performed using the stratified Cochran-Mantel-Haenszel (CMH) method.
25 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
Measure Description
Time Frame
The effectiveness of GenSci048 administered by subcutaneous injection
Time Frame: From Baseline until end of study/early termination visit (up to 29 weeks)
The change of different ophthalmic parameters at weeks 5, 9, 13, 17, 21, and 25 to baseline and best state achieved prior to week 5(inclusive).
From Baseline until end of study/early termination visit (up to 29 weeks)
The Pharmacokinetic (PK) characteristics and immunogenicity of GenSci048 administered by subcutaneous injection
Time Frame: 197 days
PK; Incidence of anti-drug antibody (ADA) and neutralizing antibody (NAb) (if applicable).
197 days
Incidence and severity of treatment-emergent adverse events (TEAEs)
Time Frame: 197 days
197 days

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
