NVAMD Satellite Study

August 28, 2018 updated by: Johns Hopkins University

A Multi-Satellite Comparison of Standard-of-Care, Physician-Based Retinal Evaluation Versus Physician-Guided Diagnostic Evaluation in the Management of Neovascular Age-Related Macular Degeneration With Anti-Vascular Endothelial Growth Factor Therapy

Intravitreal delivery of anti-vascular endothelial growth factor (VEGF) drugs has revolutionized the management of neovascular age-related macular degeneration (NVAMD). However, the requirement for near monthly administration of therapy coupled with the growing number of patients needing treatment has become a universal challenge in efficient delivery of care for retina physicians. While many retina practices have both increased the size of their staffs to accommodate the growing patient population and increased efficiency with the aid of digital photography, patient encounter times in clinic continue to increase, often spanning 2-4 hours. While maintaining the highest level of patient care, a streamlined alternative in the evaluation of patients with NVAMD to determine whether intravitreal therapy with an anti-VEGF agent is indicated at a particular office visit would be desirable.

This multi-satellite, prospective, randomized pilot study will compare standard-of-care, physician- based retinal evaluation, defined as retinal examination by a physician and standard imaging with optical coherence tomography (OCT) and optional fluorescein angiography (FA), versus physician-guided diagnostic evaluation, defined as standard imaging with OCT and optional FA without retinal examination by a physician in the management of NVAMD with anti-VEGF therapy. Outcomes for this study are aimed primarily at demonstrating that the physician-guided diagnostic approach to managing patients with NVAMD is not inferior to the physician-based retinal evaluation based on measures such as a change from baseline in visual acuity and in central subfield thickness (CSF) on OCT. Other outcomes to be assessed in this study are length of visit times, numbers of intravitreal injections of anti-VEGF agents administered, numbers of diagnostic tests performed to determine whether treatment should be given at each visit, and frequency of retinal examinations performed for each participating patient in each cohort. Perceptions of quality of vision and patient satisfaction will be captured by interviews with patients following each clinic visit; clinical impressions of physicians will be captured by a brief physician survey. Finally, the feasibility of recruiting patients, as measured by how many eligible patients are seen at each Wilmer satellite, how many patients agree to be randomized, how many patients follow-up, and the attrition rates at the 4 and 8-month outcome visits will be assessed.

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

18 years to 100 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Inclusion criteria:

  • Established diagnosis of NVAMD in one or both eyes
  • Received 2 or more intravitreal injections of anti-VEGF therapy from the retinal physician during the prior 6 months
  • Need for more therapy on a near monthly basis is anticipated
  • Usual corrected visual acuity (UCVA) of at least one eye must be 20/200 or better
  • Must be physically able to cooperate with OCT and other diagnostic imaging procedures
  • Must be able to give informed consent and be able to complete telephone surveys

Exclusion criteria:

  • Systemic disease that can affect the peripheral retina (e.g., diabetes mellitus, sickle cell)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
No Intervention: SOC Examination Based Cohort
Participants in this arm will receive standard of care (SOC) retinal examinations at each study visit.
Active Comparator: Physician-Guided Diagnostic
Participants in this arm of the study will only receive the physical standard-of-care retinal examination at the 4-month and -month office visits, unless requested by the Physician-Investigator or study participant. At each standard study visit, the physician will use diagnostic imaging to determine if the participant will receive the anti-VEGF injection.
Procedure: Physician-guided diagnostic
NVAMD participants in the physician-guided diagnostic arm will have receive injections based on diagnostic imaging provided by optical coherence tomography and optional fluorescein angiography, those in this group will only receive retinal examinations at the 4- and 8-month clinic visits.
