iSONEP to Treat Persistent Pigment Epithelial Detachment (PED) in Subjects With Exudative Age-Related Macular Degeneration (AMD) or Polypoidal Choroidal Vasculopathy (PCV) (PED)

April 22, 2013 updated by: Lpath, Inc.

A Phase 1b Multi-Center, Open-Label and Randomized Study of iSONEP (Sonepcizumab/LT1009) Administered as Intravitreous Injections to Subjects With PED Secondary to Exudative Age-Related Macular Degeneration or Polypoidal Choroidal Vasculopathy

LT1009-Oph-002 is a Phase 1b study designed to evaluate the safety and potential efficacy of iSONEP following one, two or three injections of iSONEP, as needed, for the treatment of Pigment Epithelial Detachment (PED) secondary to PED Secondary to Exudative Age-Related Macular Degeneration (AMD) or Polypoidal Choroidal Vasculopathy (PCV).

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

Sixteen (16) subjects per dose group who have received a minimum of 3 and no more than 7 doses of an anti-VEGF agent (i.e., Lucentis or Avastin), and whose PED has not decreased by greater than 25% in height despite therapy, will be enrolled for a total of 32 subjects. The presence of PED diagnosed by the Investigator will be confirmed by SDOCT, ICG and FA by a digital imaging reading center prior to subject enrollment. The ability of iSONEP to induce regression of persistent PED in subjects with exudative AMD or PCV despite previous treatment with an anti-VEGF agent will be evaluated.

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

46 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study
