  Purpose

The purpose of this study is to determine the safety, efficacy and pharmacokinetics of OMS302 (the study drug) for maintaining intraoperative mydriasis and preventing post operative pain in individuals undergoing Intraocular Lens Replacement (ILR) surgery.


Condition Intervention Phase
Intraocular Lens Replacement
Drug: OMS302
Drug: Placebo
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Phase 3 Randomized, Double-Masked, Placebo-Controlled Study of the Pharmacokinetics of OMS32 and the Effect of OMS302 on Intraoperative Pupil Diameter and Early Postoperative Pain in Subjects Undergoing Intraocular Lens Replacement With Phacoemulsification

Further study details as provided by Omeros Corporation:

Primary Outcome Measures:
  • Intraoperative pupil diameter [ Time Frame: Intraoperative ] [ Designated as safety issue: No ]
    Change in pupil diameter over time from surgical baseline to end of the surgical procedure determined by video capture during ILR.

  • Pain during the early postoperative period [ Time Frame: 12 hours ] [ Designated as safety issue: No ]
    Postoperative pain as measured by the Visual Analog Scale at 2, 4, 6, 8 and 10-12 hours after ILR surgery.


Secondary Outcome Measures:
  • Intraoperative pupil diameter [ Time Frame: Intraoperative ] [ Designated as safety issue: No ]
    Proportion of subjects having a pupil diameter >= 6mm at cortical clean-up.

  • Intraoperative pupil diameter [ Time Frame: Intraoperative ] [ Designated as safety issue: No ]
    Proportion of subjects having a pupil diameter < 6mm anytime during surgery.

  • Moderate-to-severe pain pain during the early postoperative period [ Time Frame: 12 hours ] [ Designated as safety issue: No ]
    Proportion of subjects reporting moderate-to-severe pain at any timepoints during 12 hours postoperatively.

  • No Pain during the early postoperative period [ Time Frame: 12 hours ] [ Designated as safety issue: No ]
    Proportion of subjects reporting no pain at all timepoints during 12 hours postoperatively.

  • Pain during the late postoperative period [ Time Frame: 14 days ] [ Designated as safety issue: No ]
    Postoperative pain as measured by the Visual Analog Scale at 24 and 48 hours, and Days 3-7 and 14 after ILR surgery.

  • Safety as measured by adverse events [ Time Frame: 90 days ] [ Designated as safety issue: Yes ]
    Safety as assessed by the incidence of adverse events and serious adverse events through day 90.

  • Postoperative photophobia [ Time Frame: 14 days ] [ Designated as safety issue: No ]
    Photophobia as measured by the photophobia scale of the NRS at 2, 6, 24, and 48 hours, and 7 and 14 days after surgery.

  • Postoperative best-corrected visual acuity (BVCA) [ Time Frame: 90 days ] [ Designated as safety issue: Yes ]
    BVCA as measured using the Early Treatment Diabetic Retinopathy Study method at 24 and 48 hours, and 7, 14 and 90 days after surgery.

  • Postoperative inflammation [ Time Frame: 90 days ] [ Designated as safety issue: No ]
    Postoperative inflammation as measured using the Summed Ocular Inflammation Score at 24 and 48 hours, and 7, 14 and 90 days after surgery.

  • Systemic Pharmacokinetics of OMS302 [ Time Frame: 24 hours ] [ Designated as safety issue: Yes ]
    Pharmacokinetics will be evaluated using plasma concentrations of OMS302 at baseline and at approximately 15 and 30 minutes and 1, 2, 4, 8 and 24 hours following initiation of study drug administration.

Arms Assigned Interventions
Experimental: OMS302
OMS302 diluted in Balanced Salt Solution and administered as irrigation solution during Intraocular Lens Replacement surgery.
Drug: OMS302
OMS302 drug product will be supplied as a sterile, clear colorless liquid, free from particulates of foreign matter. Each vial contains a nominal 4.5 mL solution containing 60.75 mM phenylephrine HCl and 11.25 mM ketorolac tromethamine formulated in a 20mM sodium citrate buffer (pH 6.3 +/- 0.5). For administration to patients, 4.4 mL of the drug product is added to a 500 mL bottle of commercially available BSS solution through a syringe filter. This will achieve 4.0 mL of the drug product in a 500 mL bottle of BSS solution.
