This phase 2 trial is a randomized, double-blind, placebo-controlled, multicenter study in patients with wet AMD to assess the efficacy and safety of NT-101 topical ophthalmic solution (0.20 mM) administered into the study eye twice daily (BID) for 12 weeks.
This study will consist of a 4-week screening, 12-week treatment, and 4-week follow-up. After completing screening procedures, approximately 66 eligible subjects will be randomized in a 1:1 ratio to receive 0.20 mM of NT-101 or placebo to be self-administered (or by a caregiver) two drops of NT-101 or placebo into the study eye twice daily for 12 weeks. Following the baseline visit, all study subjects will return to the clinic for study visit assessments at Weeks 4, 8, and 12. Subjects who discontinue early will complete an early termination visit for safety assessments. A follow-up will occur 4 weeks after the end of the treatment period (the last dose) and will include safety and efficacy assessments.
Clinical assessments include BCVA, slit-lamp examination, intraocular pressure (IOP) measurement, optical coherence tomography (OCT), indirect ophthalmoscopy/dilated fundus examination, fundus photography, and fundus fluorescein angiography (FFA). Adverse events (AEs) will be recorded at all study visits.
Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
CNV lesions secondary to AMD that affect the central subfield in the study eye that meet the following criteria at Screening:
Either no previous treatment in the study eye with anti-VEGF therapy (treatment naïve) or previously treated study eye with adequate from the baseline visit as defined below:
Biosimilars
Female participants of 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 throughout the course of the study and 3 months after their last study administration. Acceptable methods of contraception include:
Exclusion Criteria:

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A planned gap after a treatment, so that its effects can lessen before the study treatment or a study assessment. Ask the study team and the doctor who prescribed it before changing any medicine.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.
Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

A planned gap after a treatment, so that its effects can lessen before the study treatment or a study assessment. Ask the study team and the doctor who prescribed it before changing any medicine.

Started Jun 2026 (actual). Primary completion is estimated for Feb 2028, 20 months after the start.
Of 66 industry-sponsored phase 2 interventional studies under Macular Degeneration, half reached primary completion within 22 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 30. This study's planned 20 months is close to that.
Counting every sponsor, half of 83 studies reached it within 24 months; a quarter within 16 and three quarters within 35.
How these figures are worked out, and which studies are left out of them.
