Details and patient eligibility

About

This study has two main objectives. The first objective is to study the pharmacokinetics of topical netarsudil administration in the posterior segment of the eye, where netarsudil must exert its effect in order to prevent formation of tractional membranes.

The second objective is to assess the safety profile of topical netarsudil in the pre- and post-operative periods. A secondary objective of the study is to begin to assess signs of efficacy in preventing formation of tractional membranes post-operatively.

Full description

This is an open-label, randomized study that will test the safety and pharmacokinetics of topical netarsudil at a dose frequency of once-daily in two cohorts of patients: those with primary rhegmatogenous detachments, and those with established proliferative vitreoretinopathy. The intervention will be topical application of Netarsudil from time of diagnosis of retinal detachment to 16 weeks post-operatively.

Patients will be randomized to one of the following groups:

  • The primary rhegmatogenous detachment cohort: A total of 24 study subjects (24 eyes) will be stratified by their lens status (12 phakic versus 12 pseudophakic). All patients will receive once per day dosing of netarsudil.
  • The proliferative vitreoretinopathy cohort: A total of 24 study subjects (24 eyes) will be stratified by their lens status (12 phakic versus 12 pseudophakic). All patients will receive once per day dosing of netarsudil.

After surgery, patients will continue on once per day dosing of Netarsudil for a total of 16 weeks post-op.
