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

65 years and older (Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Autofluorescence atrophy area changes in treated eyes compared with sham group
Time Frame: 1 year
Stabilization of enlargement of hypoautofluorescent area (atrophy) or at most a maximum increase of no more than 20% compared with baseline in treated subjects compared with placebo group from baseline until follow-ups
1 year
Autofluorescence atrophy area changes in treated eyes compared with sham group (1)
Time Frame: 1 year
Stabilization of the enlargement of the hyperfluorescent area (atrophy enhancement) or at most a maximum increase of not more than 20% from the baseline
1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure

ETDRS visual acuity
Time Frame: 1 year
Increase of at least two lines from baseline measurement and/or to the contralateral untreated eye at 3 and 6, 12, months.

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Evaluation of therapy safety
Time Frame: 1 year
Evaluation of major ocular adverse events (bacterial or fungal septic endophthalmitis, retinal detachment, vitreous proliferative-fibrotic reaction with retinal traction, secondary glaucoma, phthisis bulbs, iris rubeosis), studied at slit-lamp evaluation in the anterior and posterior chambers.
