Investigating MG-O-1002 Eye Drops for Age-Related Macular Degeneration

A Phase II Trial to Evaluate the Efficacy and Safety of Topical Ocular MG-O-1002 in Patients With Neovascular Age-Related Macular Degeneration (nAMD)

This study is testing if MG-O-1002 eye drops can help improve vision in people over 45 with a specific type of age-related macular degeneration.

What this trial studies

This Phase II study aims to evaluate the effect of MG-O-1002 eye drops on central macular thickness in participants aged over 45 with neovascular age-related macular degeneration (nAMD). The study consists of two parts: one for treatment-naïve patients and another for those previously treated with Aflibercept. By using a topical eye drop formulation, the study seeks to provide a safer and more accessible treatment option compared to traditional intravitreal injections. Participants will be monitored for efficacy and safety throughout the trial.

Who should consider this trial

Good fit: Ideal candidates are adults aged 45 and older diagnosed with active, treatment-naïve nAMD or those who have received prior Aflibercept treatment.

Not a fit: Patients with advanced nAMD requiring immediate intervention or those unable to self-administer eye drops may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could offer a safer, self-administered option for patients with nAMD, potentially improving accessibility and adherence.

How similar studies have performed: While the approach of using topical treatments for nAMD is innovative, similar studies have shown promise in other ocular conditions, indicating potential for success.

Eligibility criteria

Inclusion Criteria:

Part 1:

1. Adults aged 45 years or older with a diagnosis of nAMD
2. Diagnosis in the study eye of active, pathologic, newly diagnosed and treatment naïve (i.e., no previous anti-VEGF treatment or other surgery in the study eye)
3. Visual acuity from 20/25 to 20/200 in the study eye
4. Total lesion size (including neovascularization, blood) ≦12 disc areas (30.5 mm2) as assessed by Fluorescein Angiography.
5. Demonstrate the ability, or have a family member who is willing and able to, instill topical ocular drops in the study eye.
6. Ability to give written informed consent and comply with study procedures.

Part 2:

1. Adults aged 45 years or older with a diagnosis of nAMD.
2. Participant with nAMD previously treated with 3 injections of Aflibercept within the preceding 4 months, and received the last injection within 30 to 21 days before visit 1 of this study.
3. Demonstrate the ability, or have a family member who is willing and able to, instil topical ocular drops in the study eye.
4. Ability to give written informed consent and comply with study procedures.

Exclusion Criteria:

Part 1:

1. Prior use within the last 2 months, or a high possibility of requiring treatment with anti-VEGF therapy (except the study drug) in both eyes during the study.
2. Abnormal regions identified by Fundus Autofluorescence (FAF) and Optical Coherence Tomography (OCT) involving the center of the fovea are caused by retinal pigment epithelium (RPE) atrophy, RPE tear, photoreceptor attenuation, or fibrosis/scar tissue.
3. Significant retinal serous pigment epithelial detachment (PED) involving the fovea.
4. History of, or current clinical evidence in the study eye of aphakia, diabetic macular edema, any ocular inflammation or infection, pathological myopia, retinal detachment, advanced glaucoma, and/or significant media opacity, including cataract.
5. History or evidence of the following surgeries in the study eye: penetrating keratoplasty or vitrectomy; corneal transplant; corneal or intraocular surgery within 3 months of Screening.
6. Uncontrolled hypertension despite the use of antihypertensive medications.
7. Diagnosis of Type 1 or Type 2 diabetes.
8. Use of medications that in the opinion of the Investigator could interfere with study results.
9. Participation in any investigational drug or device study, systemic or ocular, within the past 3 months.
10. Women who are pregnant or breast feeding.
11. Women of child-bearing potential who are not using an effective form of birth control.
12. Known serious allergies or hypersensitivity to the fluorescein dye used in angiography, or to the components of the MG-O-1002 formulation, or to topical anesthetics.
13. In the opinion of the investigator, subject who is not suitable for or not likely be benefited from the study treatment.

Part 2:

1. More than 30 days between 3rd injection of Aflibercept and Visit 1.
2. Patients who have received 3 injections of Aflibercept within the last 3 months and need continued treatment in the fellow eye.
3. Significant retinal serous pigment epithelial detachment (PED), atrophy, or fibrosis/scar involving the fovea.
4. History or evidence of the following surgeries in the study eye: penetrating keratoplasty or vitrectomy; corneal transplant; corneal or intraocular surgery within 3 months of Screening.
5. Active intraocular inflammation or uveitis or scleritis or episcleritis in the study eye or ocular or periocular infection in either eye.
6. Uncontrolled hypertension despite the use of antihypertensive medications.
7. Diagnosis of Type 1 or Type 2 diabetes.
8. Use of medications that in the opinion of the Investigator could interfere with study results.
9. Participation in any investigational drug or device study, systemic or ocular, within the past 3 months.
10. Women who are pregnant or breast feeding.
11. Women of child-bearing potential who are not using an effective form of birth control.
12. Known serious allergies or hypersensitivity to the fluorescein dye used in angiography, or to the components of the MG-O-1002 formulation, or to topical anesthetics.
13. In the opinion of the investigator, subject who is not suitable for or not likely be benefited from the study treatment.
