研究概览
简要总结
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.
详细描述
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.

入选标准
- •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.
- •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
- •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.
- •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).
排除标准

- •Uncontrolled diabetes (HbA1c > 12.0%)
- •Total bilirubin > 1.5 × Upper Limit of Normal (ULN)
- •Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) > 2.5 × ULN

- •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.
