Current Trials for Vitreosolve® for Diabetic Retinopathy

Vitreosolve® is being studied in two Phase III trials conducted in multiple sites in the United States, India and Mexico.

PVD-301 Study

The objective of the PVD-301 study is to evaluate the safety and efficacy of Vitreosolve® ophthalmic intravitreal injection in patients with nonproliferative diabetic retinopathy (NPDR), a medical condition which affects the health of the eyes resulting in bleeding, inappropriate blood vessel growth, and severe vision loss or blindness. Vitreosolve® is used for inducing a posterior vitreous detachment (PVD) in these patients to prevent the loss of vision. This is a prospective, randomized, double-masked, placebo-controlled study. Approximately 400 patients with NPDR in the United States and India will be enrolled and randomized into one of two study groups:  active study group or control group.  The duration of the study is approximately seven months.

PVD-302 Study

The objective of the second clinical trial, PVD-302, is to evaluate the safety and efficacy of Vitreosolve® ophthalmic intravitreal injection in patients who have nonproliferative diabetic retinopathy (NPDR), a medical condition which affects the health of your eyes resulting in bleeding, inappropriate blood vessel growth, and severe vision loss or blindness. Vitreosolve® is used for inducing a posterior vitreous detachment (PVD) in these patients to prevent the loss of vision. This is a prospective, randomized, double-masked, placebo-controlled study. Approximately 150 patients with NPDR in Mexico will be enrolled and randomized into one of two study groups: active study group or control group. The duration of the study is approximately five months.

Sites in the United States, India and Mexico are actively recruiting subjects.
