Is this trial a fit for you?
✓Likely a good fit
Adults aged 50 years or older with CNV lesions affecting the central macula and BCVA between 35 and 78 letters in the study eye.
✕Probably not a fit
Patients without central subfield involvement, unsuitable BCVA range, or those with insufficient washout from prior anti-VEGF therapy may not benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a phase 2, randomized, double-blind, placebo-controlled study conducted at multiple centers to evaluate the safety and efficacy of NT-101 topical ophthalmic solution for wet AMD. Participants will receive either NT-101 0.20 mM or placebo in the study eye for 12 weeks, with follow-up visits at Weeks 4, 8, and 12 and a safety check 4 weeks after the last dose. The trial includes a 4-week screening, and safety and efficacy will be monitored through measurements such as BCVA, OCT, IOP, and retinal imaging. Approximately 66 eligible subjects will be randomized 1:1, and both eyes will be assessed as part of the study’s comprehensive ocular examinations.
Why it matters
Potential benefit: If successful, NT-101 could provide an effective topical treatment option for improving vision or slowing progression in wet AMD.
How similar studies have gone: Previous studies of similar topical agents in AMD have shown mixed results; this study explores a novel topical approach in a controlled trial setting.

Inclusion Criteria:
1. Subject who is male or female ≥ 50 years of age at Screening.
2. CNV lesions secondary to AMD that affect the central subfield in the study eye that meet the following criteria at Screening:
* CNV lesions affect the fovea, as evidenced by fluorescein angiography in study eye.
* Intraretinal and/or subretinal fluid affecting the central subfield visible on OCT. If fluid is not visible due to previous treatment, earlier documented OCT images showing fluid for diagnosing wet AMD can be reviewed to fulfill this criterion.
3. BCVA between 35 and 78 letters, inclusive, in the study eye at Screening using ETDRS testing, with BCVA decrement primarily attributable to wet AMD.
4. Either no previous treatment in the study eye with anti-VEGF therapy (treatment naïve) or previously treated study eye with adequate washout from the baseline visit as defined below:
* Lucentis (ranibizumab): 30-day washout
* Avastin (bevacizumab): 30-day washout
* Eylea (aflibercept): 60-day washout
* Eylea (aflibercept) high dose 8mg: 70-day washout
* Vabysmo (faricimab-svoa): 70-day washout
* Biosimilars
* Byooviz (ranibizumab-nuna): 30-day washout
* Cimerli (ranibizumab-eqrn): 30-day washout
* Pavblu (aflibercept-ayyh): 60-day washout
* Afqlir (aflibercept): 60-day washout
* Enzeevu (aflibercept-abzv): 60-day washout
* Ahzantive (aflibercept-mrbb): 60-day washout
5. Demonstrates the ability to instill eye drops (by the subject or caregiver) in the study eye, express willingness to comply with the dosing regimen, and commit to attending all study visits.
6. Understands and voluntarily signs an informed consent form.
7. Female participants of childbearing potential and male participants able to father children must have (or have a partner who has) had a hysterectomy or vasectomy, be completely abstinent from intercourse, or agree to practice two acceptable methods of contraception throughout the course of the study and 3 months after their last study administration. Acceptable methods of contraception include:

* intrauterine device,
* barrier methods (diaphragm, condom) with spermicide, or

Subject who has a medical condition that, in the opinion of the Investigator, would preclude participation in the study (e.g., unstable medical status including psychiatric disorder, cardiovascular disease, poor glycemic control, and significant medical condition including end-stage renal disease and severe liver disease).
4. History of stroke or myocardial infarction (MI) within 6 months prior to Screening.
5. Subject who has had major surgery within 3 months prior to Screening.

11. Media opacities or abnormalities in the study eye that would preclude visualization of the retina.

16. Subject who has a history of vitrectomy in the study eye, unless otherwise allowed at the discretion of the Investigator.

18. Subject who has any history of intraocular inflammation in either eye, other than what would be expected in the normal post-operative course following prior routine ocular surgery such as cataract surgery.
19. Subject who has other retinal pathologies in the study eye that would interfere with vision, such as evidence of diabetic macular edema or diabetic retinopathy (defined as more than one microaneurysm).
20. Non-study eye with a BCVA worse than 20 letters at Screening using ETDRS testing.
