  Purpose

Plasmin is expected to create a posterior vitreous detachment. The pharmacological creation of a posterior vitreous detachment may be beneficial in a variety of conditions.


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

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Investigator)
Primary Purpose: Treatment
Official Title: A Multicenter, Randomized, Double Masked, Placebo Controlled, Sequential Dose Response 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 Grade A Posterior Vitreous Detachment (PVD) [ Time Frame: 14 Days ] [ Designated as safety issue: No ]
    PVD at the disc and macula post plamin injection


Enrollment: 29
Study Start Date: April 2006
Study Completion Date: August 2007
Primary Completion Date: August 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
