October 28, 2024 updated by: Oxular Limited

A Multi-Center, Randomized, Two-Arm, Parallel-Group, Single-masked, 24-week, Clinical Trial to Evaluate Safety and Tolerability of Two Dose Levels of Suprachoroidal Triamcinolone Acetonide Administered With the Oxulumis® Ophthalmic Administration Device in Subjects With Diabetic Macular Edema

The purpose of this clinical trial is to evaluate the safety and tolerability of suprachoroidal microcatheterization with the Oxulumis® device for a randomized treatment with two dose levels of Triesence® in subjects with Diabetic Macular Edema.

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

Twenty-four (24) week, randomized, two-arm, single-masked, clinical trial to evaluate safety, tolerability, and to explore the efficacy of two dose levels of suprachoroidal triamcinolone acetonide suspension (Triesence®, 2.4 mg, and 4.0mg) administered using the Oxulumis® microcatheterization device in subjects with previously treated Diabetic Macular Edema.

After a screening period, approximately 20 eligible Diabetic Macular Edema subjects will be treated using a 1:1 ratio to receive a single administration of one of two dose levels of triamcinolone acetonide (low dose, 2.4mg. or mid-dose, 4.0mg, respectively). If for any reasons treatment in randomized subjects cannot be completed, additional consecutive subjects will be randomized until the target number of approximately 20 treated subjects is reached.

From Week 4, subjects will be assessed for the need for follow-on treatment. The follow-up period after treatment administration will be up to twenty-four (24) weeks.

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 and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

  • Short-lived, limited, or no response to prior ocular injection therapy

Exclusion Criteria:

  • Macular edema is considered due to a cause other than diabetes mellitus in the study eye.

  • Active proliferative diabetic retinopathy (PDR) or sequelae of PDR in the study eye.
  • Active malignancy or history of malignancy within the past five years.
  • Prior intravitreal (IVT) treatment with anti-Vascular endothelial growth factor (VEGF) in the study eye: last injection within four weeks, before screening
  • Prior ocular treatment with steroids in the study eye: last injection (intra- or periocular) with triamcinolone acetonide within three (3) months, with dexamethasone implant (Ozurdex®) within six (6) months before screening.
  • Prior treatment with longer duration steroid implants (e.g., fluocinolone acetonide IVT implant, Iluvien®) is exclusionary.
  • Prior treatment with suprachoroidal steroids is exclusionary.
  • Uncontrolled diabetes with a hemoglobin A1c (HbA1c) > 12% or any other uncontrolled systemic disease at screening.

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
Frequency of Ocular Adverse Events, Systemic Adverse Events, Serious, and Treatment-emergent Non-serious Adverse Events
Time Frame: Day 0 up to Week 24 (per protocol individual trial duration per participant)
Treatment-emergent ocular adverse events are defined as an ocular event that emerges following the start of administration of Triesence® with the Oxulumis® microcatheter at Visit 2 (Baseline, Day 0)
Day 0 up to Week 24 (per protocol individual trial duration per participant)
Frequency of Adverse Device Effects and Frequency of Serious Adverse Device Effects

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.
Outcome Measure
Measure Description
Time Frame
