November 22, 2016 updated by: B.Braun Avitum AG

An Open-label, Single Center Study to Evaluate the Efficacy and Safety of Heparin-induced Extracorporeal Lipoprotein Precipitation (H.E.L.P.) Therapy as a Treatment for Non-exudative (Dry) Age-related Macular Degeneration (AMD)

This is an open-label, single center clinical investigation to evaluate the efficacy and safety of Heparin-induced Extracorporeal Lipoprotein Precipitation (H.E.L.P.) Therapy as a treatment for non-exudative (dry) Age-related Macular Degeneration (AMD). A total of 14 clinic visits are scheduled, one baseline visit, 8 visits for H.E.L.P. therapy treatments (to be performed over a period of 12 weeks for each patient) and 5 follow-up visits to be performed one week following the 4th H.E.L.P. therapy session and 12 weeks, 24 weeks, 36 weeks and 52 weeks after the final H.E.L.P. therapy session.

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.

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.
