Evaluating OLX10212 for treating neovascular age-related macular degeneration

Evaluation of the Safety and Tolerability of OLX10212 in Patients With Neovascular Age-Related Macular Degeneration

What this trial studies

This Phase 1, multicenter, open-label study investigates the safety and tolerability of OLX10212, a small interference RNA, in patients with neovascular age-related macular degeneration (AMD). The study consists of two parts: Part A involves single ascending doses, while Part B focuses on multiple ascending doses of OLX10212 administered via intravitreal injection. Up to 42 participants will be enrolled to assess both the safety and preliminary efficacy of the treatment, alongside pharmacokinetic evaluations. The study aims to improve retinal inflammation associated with AMD through this novel therapeutic approach.

Who should consider this trial

Good fit: Ideal candidates are men and women aged 50 and older with active neovascular AMD and specific visual acuity criteria.

Not a fit: Patients with other forms of macular degeneration or those who do not meet the inclusion criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients suffering from neovascular age-related macular degeneration.

How similar studies have performed: While this is the first use of OLX10212 in AMD patients, similar approaches using RNA interference have shown promise in other conditions.

Eligibility criteria

Inclusion Criteria:

1. Men and women ≥50 years of age
2. Primary subfoveal CNV lesions secondary to AMD, including juxtafoveal lesions that affect the fovea, as evidenced by FA in the study eye
3. CNV must be ≥50% of the total lesion size in the study eye
4. ETDRS BCVA score ranging from 20/60 to 20/400 in the study eye
5. Clear ocular media and adequate pupillary dilation (able to dilate pupil to ≥4 mm using standard mydriatics) in the study eye to permit good stereoscopic fundus photography
6. Retinal thickness ≥200 μm in the macular region of the study eye as measured by SD-OCT, and active neovascular AMD, in the opinion of the Investigator
7. Willing, committed, and able to return for all clinic visits and complete all study-related procedures
8. Able to read (or if unable to read due to visual impairment, be read to verbatim by the person administering the informed consent or by a family member), understand, and willing to sign the informed consent form

Exclusion Criteria:

1. Any prior systemic treatment for neovascular AMD in either eye, except dietary supplements or vitamins or systemic anti-VEGF therapy, or planned use at any time during the study
2. Any prior treatment in the study eye with another investigational agent to treat neovascular AMD within 6 months prior to Day 0 or planned use at any time during the study
3. Prior treatment with anti-VEGF agents as follows:

   1. Anti-VEGF therapy in the study eye within 4 weeks prior to Day 0
   2. Anti-VEGF therapy in the study eye at any time to which there was no response, as defined by the presence of at least 1 of the following conditions: (1) persistent (plasma) fluid exudation, (2) unresolved or new hemorrhage, and (3) progressive lesion fibrosis
   3. Anti-VEGF therapy in the fellow eye with an investigational agent (not FDA approved, unless it is bevacizumab) within 3 months prior to Day 0 (prior treatment with an FDA approved anti-VEGF therapy in the fellow eye is allowed at any time)
   4. Systemic anti-VEGF therapy, investigational or FDA approved, within 3 months prior to Day 0 or planned use at any time during the study
4. Scar or fibrosis in the study eye involving \>50% of the total lesion size
5. Retinal pigment epithelial tears or rips in the study eye involving the macula within 6 months prior to Day 0
6. History of any vitreous hemorrhage in the study eye within 4 weeks prior to Day 0
7. Presence of other causes of CNV in the study eye, including pathologic myopia, ocular histoplasmosis syndrome, angioid streaks, choroidal rupture, or multifocal choroiditis
8. Clinical evidence of moderate or severe diabetic retinopathy, diabetic macular edema, or any other inflammatory or occlusive vascular disease affecting the retina (other than AMD) in either eye
9. History of stage ≥2 macular hole in the study eye
10. Any prior intraocular or periocular surgery on the study eye within 3 months prior to Day 0 (lid surgery is allowed if it took place at least 1 month prior to Day 0 and is unlikely to interfere with OLX10212 injection). Prior vitrectomy in the study eye, surgery for retinal detachment in the study eye, and prior trabeculectomy or other filtration surgery in the study eye are not permitted at any time
11. Uncontrolled glaucoma (defined as IOP ≥25 mmHg despite treatment with antiglaucoma medication) in the study eye
12. Glaucoma in the study eye requiring treatment with 3 or more antiglaucoma medications
13. Active intraocular inflammation or history of uveitis in either eye
14. Presence or history of ocular or periocular infection in either eye within 2 weeks prior to Day 0
15. Presence of scleromalacia in the study eye
16. Aphakia or absence of posterior capsule in the study eye (unless due to yttrium aluminum garnet \[YAG\] posterior capsulotomy)
17. Prior therapeutic radiation in the region of the study eye or planned use at any time during the study
18. Significant media opacities, including cataract, in the study eye that, in the opinion of the Investigator, could interfere with visual acuity, assessment of safety, or fundus photography
19. Any concurrent intraocular condition in the study eye (eg, cataract) that, in the opinion of the Investigator, could (1) require either medical or surgical intervention during the 24- or 32-week study period (Part A or Part B, respectively), (2) increase the risk to the patient beyond what is to be expected from standard intraocular injection procedures, or (3) otherwise interfere with the injection procedure or efficacy or safety evaluation
20. History of other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that might affect interpretation of the results of the study or renders the patient at high risk for treatment complications
21. Participation as a patient in any clinical study or prior systemic or ocular treatment with an investigational agent within 12 weeks prior to Day 0
22. Prior systemic or intraocular treatment with long-acting steroids within 6 months prior to Day 0 or planned use at any time during the study
23. History of allergy to povidone iodine
24. Known allergy to fluorescein sodium for injection in angiography
25. Unwillingness among females who are pregnant, breastfeeding, or of childbearing potential to practice adequate contraception throughout the study. Adequate contraceptive measures include oral contraceptives (stable use for ≥2 cycles prior to Day 0), intrauterine device, Depo-Provera® (Pfizer, Inc., New York) or Norplant System® (Pfizer, Inc., New York) implants, bilateral tubal ligation, vasectomy, and condom or diaphragm plus contraceptive sponge, foam, or jelly. A female is considered to be of childbearing potential unless she is premenstrual, 1 year postmenopausal, or 3 months post-surgical sterilization. All females of childbearing potential, including those with post-tubal ligation, must have a negative urine pregnancy test result at Day 0 and every 4 weeks as outlined in the Schedule of Activities. A negative serum pregnancy test must be obtained at Screening.
