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

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

30 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. The participant must have macular edema associated branch retinal vein occlusion.
  2. The participant has retinal photographs, optical coherence tomography (OCT) and angiography of sufficient quality, allowing assessment of the macular area according to standard clinical practice.
  3. The participant must be willing and able to comply with the protocol.

Exclusion Criteria:

  1. The participant has BRVO with other ocular vascular diseases such as central retinal vein occlusion, hypertensive retinopathy, etc.
  2. The participant has any additional ocular diseases that have irreversibly compromised or could likely compromise the visual acuity of the study eye including amblyopia, anterior ischemic optic neuropathy, clinically significant diabetic macular edema, severe non proliferative diabetic retinopathy, or proliferative diabetic retinopathy.
  3. The participant has a history of treatment for BRVO in the study eye with focal laser photocoagulation, intravitreal triamcinolone acetonide injection or intravitreal Bevacizumab injection
  4. The participant has a history of intraocular surgery (including lens replacement surgery).
  5. The participant has a history of ocular trauma, or current ocular or periocular infection (including any history of ocular herpes zoster or simplex).

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Monotherapy group
The monotherapy group receive intravitreal injection of 1.25 mg/0.05 ml bevacizumab. The injections are performed using 0.5% proparacaine drops for topical anesthesia under sterile conditions. The bevacizumab is injected through the pars plana using a 30-gauge needle.
Procedure: intravitreal bevacizumab monotherapy
The monotherapy group receive intravitreal injection of 1.25 mg/0.05 ml bevacizumab. The injections are performed using 0.5% proparacaine drops for topical anesthesia under sterile conditions. The bevacizumab is injected through the pars plana using a 30-gauge needle.
Experimental: Combined group
The combined group receive intravitreal injection of 1.25 mg/0.05 ml bevacizumab and posterior subtenon injection of 40 mg/1.0 ml triamcinolone acetonide. The injections are performed using 0.5% proparacaine drops for topical anesthesia under sterile conditions. The Bevacizumab is injected through the pars plana using a 30-gauge needle and triamcinolone acetonide is injected through the posterior subtenon area (near macula) by using a 27-gauge needle at the same time.
Procedure: combined therapy of posterior subtenon triamcinolone acetonide and intravitreal bevacizumab injection

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
Changes of Central Retinal Thickness
Time Frame: baseline, 1, 3, 6 months after injection
Changes of central retinal thickness on optical coherence tomography (OCT) at baseline and 1, 3, 6 month after injection
baseline, 1, 3, 6 months after injection

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
Additional Intravitreal Bevacizumab Injection
Time Frame: 6 months
Comparison of the additional intravitreal bevacizumab injection of intravitreal bevacizumab monotherapy or combined therapy of posterior subtenon triamcinolone acetonide and intravitreal bevacizumab during 6 months
6 months

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
