Episcleral Brachytherapy for the Treatment of Wet AMD (NEAMES)

August 28, 2023 updated by: Salutaris Medical Devices, Inc.

A Prospective Study of Episcleral Brachytherapy for the Treatment of Neovascular Age-related Macular Degeneration

This is a prospective, multi-site, safety and feasibility study of the SalutarisMD SMD-DA system for retrobulbar minimally invasive episcleral brachytherapy device in patients receiving and not responding to anti-VEGF therapy for nAMD. The trial will be open label and non-randomized. The study intervention is a one-time intervention and requires no alteration to the standard of care during the follow-up period.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Subjects will receive a single brachytherapy treatment and 36 months of follow-up.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

50 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Diagnosis of active CNV or PCV due to nAMD
  • Poor or non-responsive to FDA approved intravitreal anti-VEGF therapy for nAMD
  • BCVA 20/63 or worse Snellen equivalent in the study eye
  • Ability to understand nature/purpose of trial and to provide informed consent
  • Ability to undergo diagnostic tests and surgical interventions
  • Ability to follow instructions and complete the trial including all scheduled visits and follow-up

Exclusion Criteria:

  • Neovascularization other than due to AMD
  • Sub-foveal lesion hemorrhage obscuring >50% of lesion
  • Targeted neovascular lesion with greatest linear dimension >3750 microns or <1000 microns as determined by angiography
  • Presence of subretinal fibrosis, including disciform scar, or retinal pigment epithelial (RPE) atrophy that is extensive or foveal threatening in the study eye
  • An existing retinal pigment epithelial (RPE) tear
  • Previous treatment (excluding vitamins) for nAMD in the study eye other than anti-VEGF therapy in the last 6 months
  • A change in anti-VEGF agent in the previous two administrations
  • Anticipate a change to the anti-VEGF agent during the conduct of the study
  • Other clinically significant ocular co-morbidity including, but not limited to, glaucoma, optic neuropathy of any cause, maculopathy / retinopathy of any cause other than nAMD, scleritis, enophthalmos, microphthalmia, or other co-morbidities that in the investigator's opinion could require medical or surgical intervention to prevent or treat visual loss or media opacity that might result from that condition (i.e. severe cataracts).
  • Previous intraocular surgery in study eye other than for uncomplicated phacoemulsification cataract extraction
  • High myopia indicated by a history of refractive error of - 6D or greater (spherical equivalent), demonstrated myopic degeneration, or axial length of >26.5mm.
  • Subjects with orbital structural abnormalities, such as small (axial length <21 mm), deep set globes or other globe dystopias that, in the investigator's clinical judgment, would require a change in the angle of insertion or increase the risk of structural damage from retrobulbar anesthesia, sub-Tenon's anesthesia, or retrobulbar device positioning.
  • Media opacity sufficient to preclude adequate fundoscopy, OCT, or angiography
  • Uncontrolled systemic diseases (e.g. controlled hypertension is acceptable)
  • Type I or type II diabetes mellitus
  • Any previous therapeutic radiation to the head or neck or other areas that may have resulted in a radiation dose to the retina.
  • On anticoagulation or dual anti-platelet therapy with abnormal coagulation panel results.
  • Patient unsuitable for IV or local anesthesia
  • Any contraindication to anti-VEGF, fluorescein, indocyanine green, topical and local anesthetics, topical antiseptics, or topical antibiotics to be used during the study
  • Active ocular or periocular infection or intraocular inflammation
  • Fellow eye with a BCVA of 20/63 Snellen Equivalent or worse, with advanced AMD (neovascular or non-exudative AMD with foveal geographic atrophy), or other vision threatening disease that is not eligible for vision restoring treatment (i.e. inoperable cataracts).
  • Fellow eye is receiving anti-VEGF therapy
  • Have received any investigational treatment for any indication in the previous 30 days
  • Any condition which, in the investigators' opinion, would conflict or otherwise prevent the subject from complying with the required procedures, schedule or other study conduct
