RBM-007 in Subjects witH ExudatIve Age-related Macular Degeneration

Phase 1

Completed

• Conditions: Age-related Macular Degeneration
• Interventions: Drug: RBM-007 Injectable Solution

• Registration Number: NCT03633084
• Lead Sponsor: Ribomic USA Inc

Brief Summary

This is an open label, non-controlled, dose-escalating study assessing the safety, tolerability, and bioactivity of a single intravitreal (i.vt.) injection of RBM-007 in approximately nine subjects with exudative age-related macular degeneration.

Detailed Description

Nine subjects in three dose cohorts (3 subjects each cohort) will receive a single i.vt. injection of RBM-007 in the study eye. Subjects will be followed through Day 56.

Recruitment & Eligibility

• Sex: All
• Target Recruitment: 9

Inclusion Criteria

1. Male or female 55 years of age or older on the date of signing the informed consent form and able and willing to comply with all treatment and follow-up study procedures.

2. At Screening Visit, subjects must meet all the following inclusion criteria:

3. Must have had prior treatment in the study eye with any intravitreal vasoactive endothelial growth factor (VEGF) medication (at least 3 anti-VEGF) treatments within the prior 2-6 months), throughout which clinical examination and SD-OCT imaging has shown recurrent or persistent exudative activity, as shown by the presence of intraretinal or subretinal fluid, and/or subretinal exudation or hemorrhage.

4. Best corrected visual acuity of 65 to 20 Early Treatment of Diabetic Retinopathy Study (ETDRS) letters (20/50 to 20/400) in the study eye.

5. Presence of significant subretinal fluid and/or cystoid macular edema secondary to exudative age-related macular degeneration as assessed by optical coherence tomography in the study eye, with a minimum of 300 µm within the central subfield.

6. Total lesion size of ≤9 disc areas, lesion containing ≤50% hemorrhage and ≤50% subretinal fibrosis and ≤50% retinal pigment epithelial atrophy in the study eye.

7. Reasonably clear media and reasonable fixation ability in the study eye to allow for good quality tomography and fundus photography.

   At Baseline Visit (Day 0), subjects must meet all the following inclusion criteria:

8. Best Corrected Visual Acuity (BCVA) of 65 to 20 ETDRS letters (20/50 to 20/400) in the study eye.

9. Presence of significant subretinal and/or intraretinal fluid secondary to exudative age-related macular degeneration as assessed by SD-OCT in the study eye, with a minimum of 300 µm within the central subfield.

10. Total lesion size of ≤9 disc areas, containing ≤ 50% hemorrhage and ≤ 50% fibrosis and ≤ 50% retinal pigment epithelial atrophy in the study eye.

Exclusion Criteria

Ocular exclusion criteria:

1. BCVA better than 65 ETDRS letters (20/50) in the study eye.

2. BCVA worse than 20 ETDRS letters (20/400) in study eye.

3. Fellow eye BCVA worse than 35 ETDRS letters (20/200).

   Use of any of the following treatments to the study eye:

4. Intravitreal anti-VEGF injection (ranibizumab, aflibercept or bevacizumab) in the study eye within the past 4 weeks or less prior to Baseline Visit and RBM-007 injection.

5. Intravitreal or periocular corticosteroid, within 3 months prior to Baseline Visit (Day 0) and throughout the study;

6. Fluocinolone acetonide intravitreal implant, within 12 months prior to Baseline Visit (Day 0) and throughout the study;

7. Visudyne® (verteporfin) photodynamic therapy, within 3 months prior to Baseline Visit (Day 0) and throughout the study.

8. Uncontrolled or advanced glaucoma, defined by an intraocular pressure (IOP) of >21 mmHg or cup/disc ratio > 0.8 while on medical therapy, or chronic ocular hypotony (<6 mmHg) in the study eye.

9. Evidence of ocular disease other than exudative AMD in the study eye that may confound the outcome of the study (e.g., active diabetic retinopathy, posterior uveitis, adult vitelliform dystrophy, moderate/severe myopic degeneration).

10. History of vitrectomy surgery in the study eye.

11. Anticipated need for any ocular surgery involving the study eye during the course of the study.

12. Nd:YAG laser capsulotomy within 28 days prior to Baseline Visit (Day 0) in the study eye.

13. Intraocular surgery, including lens removal or ophthalmologic laser procedure, within 90 days prior to Baseline Visit (Day 0) in the study eye.

14. Ocular or periocular infection in either eye.

15. Pupillary dilation inadequate for good quality fundus photography in the study eye.

16. Media opacity that would limit clinical visualization, fundus photography, fluorescein angiography, or SD-OCT evaluation in the study eye.

17. History of herpetic ophthalmic infection in the study eye or adnexa.

18. Presence of known toxoplasmosis or toxoplasmosis scar in either eye.

19. Presence or history of any form of ocular malignancy including choroidal melanoma in the study eye.

Primary Outcome Measures

Name	Time	Method
Ocular Safety as Assessed Using Biomicroscopy to Investigate Ocular Tolerability	Day 56	Biomicroscopy is used by an ophthalmologist to assess the health of the front of the eye. The measure is the number of subjects with abnormal findings that were not present at screening.
Ocular Safety as Assessed Using Ophthalmoscopy to Investigate Ocular Tolerability	Day 56	Ophthalmoscopy is used by an ophthalmologist to assess the health of the back of the eye. The measure is the number of subjects with abnormal findings that were not present at screening.
