  Purpose
Plasmin is expected to create a posterior vitreous detachment (PVD) when injected directly into the eye. The pharmacological creation of a PVD may be beneficial in helping to treat a variety of conditions.

Condition Intervention Phase
Disorders Caused by Vitreo-retinal Traction. Drug: Plasmin Phase 1 Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open Label Sequential Dose Response Observational Study of Intravitreally Administered Plasmin for the Creation of a Posterior Vitreous Detachment (PVD)

Further study details as provided by Bausch & Lomb Incorporated:

Primary Outcome Measures:
  • Presence of a Posterior Vitreous Detachment (PVD) [ Time Frame: 14 days ]
    Presence of posterior vitreous detachment evaluated durning virectomy

Study Completion Date: June 2007
Primary Completion Date: May 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Plasmin
Human-derived plasmin reconstituted with sterile sodium chloride for intravitreal injection.
Drug: Plasmin
27 mg of human-derived plasmin to be reconstituted with of 0.9% Sterile Sodium Chloride for a single intravitreal injection
