What this study is about
This phase 2 trial is a randomly assigned, where neither patients nor doctors know which treatment is given, compared against an inactive treatment, conducted at multiple hospitals study in patients with wet AMD to assess the effectiveness and safety of NT-101 topical ophthalmic solution (0.20 mM) administered into the study eye twice daily (BID) for 12 weeks.

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Subject who is male or female ≥ 50 years of age at Screening.
- 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.
- BCVA between 35 and 78 letters, inclusive, in the study eye at Screening using ETDRS testing, with BCVA decrement primarily attributable to wet AMD.

- Understands and voluntarily signs an informed consent form.
- 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:
- Hormonal contraception (i.e., birth control pills, injected hormones, dermal patch, or vaginal ring),
- intrauterine device,
- barrier methods (diaphragm, condom) with spermicide, or
- surgical sterilization (hysterectomy or tubal ligation).
Exclusion criteria
- Subject who has the following illness or abnormal laboratory test values at Screening:

- Uncontrolled diabetes (HbA1c \> 12.0%)
- Total bilirubin \> 1.5 × Upper Limit of Normal (ULN)
- Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) \> 2.5 × ULN
- Prothrombin time (PT) \> 1.5 × ULN
- Hemoglobin (Hb) \< 10 g/dL (male); Hb \< 9 g/dL (female)
- Platelets \< 100 × 103 µL
- Estimated glomerular filtration rate (eGFR) \< 30 mL/min/1.73m2
- Positive results for Human Immunodeficiency Virus (HIV) or Hepatitis B or C viruses.
- Other clinically significant abnormal lab values per Investigator's judgement.
- 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).
- History of stroke or myocardial infarction (MI) within 6 months prior to Screening.
- Subject who has had major surgery within 3 months prior to Screening.
- Pregnant or breastfeeding or intending to become pregnant during the study.
- Subject with known hypersensitivity to any active substance or excipients of the investigational product, fluorescein, dilating eye drops, or any of the anesthetic and antimicrobial drops.
- Treatment with investigational therapy or participation in any other type of interventional trial within 30 days before Screening.
- Subject who has a history of AMD treatment in the study eye with Beovu® (brolucizumab) or photodynamic therapy.
- CNV in the study eye secondary to other causes or subject who has an ocular condition (other than AMD) that, in the opinion of the Investigator, may limit visual acuity improvement during the course of the study (e.g., ocular histoplasmosis, trauma, pathological myopia, angioid streaks, choroidal rupture, multifocal choroiditis, congenital eye malformations, retinal pigment epithelial tear, or posterior uveitis, etc.).
- Media opacities or abnormalities in the study eye that would preclude visualization of the retina.
- Subject who has a history of retinal detachment or retinal detachment repair surgery in the study eye, unless otherwise allowed at the discretion of the Investigator.

- Subject who has a history of ocular surgery in the study eye (including cataract extraction, any intraocular surgery, etc.) within 3 months prior to Screening or anticipated within the next 6 months following randomization.
- 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.
- 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).
- Non-study eye with a BCVA worse than 20 letters at Screening using ETDRS testing.
- Total lesion size \>12 disc areas (30.5 mm2), including blood, scar, and neovascularization, in the study eye as assessed by FA.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
