May 2, 2024 updated by: Santen Inc.

OPSIS: A Phase IIa, Randomized, Double-Masked, Placebo-Controlled, Parallel-Group, Multicenter Study Assessing the Efficacy and Safety of STN1013600 Ophthalmic Solution 0.1% and 0.3% Compared With Placebo in Subjects With Presbyopia

This is a Phase IIa study to assess efficacy and safety of STN1013600 ophthalmic solution (0.1%, and 0.3 %), twice daily when compared to Placebo in subjects diagnosed with presbyopia. This study will consist of a Screening Period of up to 15 days followed by a 2 Month Treatment Period. After the Treatment Period subjects will be followed for a one-month treatment free period.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

47 years to 55 years (Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Phakic presbyopic subjects, Male or Female between 47 and 55 years of age.
  • Distance-corrected near visual acuity (DCNVA) for each eye, as well as for binocular vision, 70 EDTRS letters or worse (equivalent to 0.3 logMAR or worse; or 20/40 Snellen or worse) at 40 cm. To be reconfirmed at Visit 2 (Baseline).
  • Best-corrected distance visual acuity (BCDVA) for each eye of 85 ETDRS letters or better (equivalent to 0.00 logMAR or better; or 20/20 Snellen or better) at 4 m. To be reconfirmed at Visit 2 (Baseline).

Exclusion Criteria:

  • Secondary cause of presbyopia in either eye as assessed by investigator (e.g., damage to lens, zonules or ciliary muscle, multiple sclerosis, cardiovascular accidents, vascular insufficiency, myasthenia gravis, anemia, influenza, measles).
  • Any history of ocular surgery (including ocular laser surgery) in either eye or plan of ocular surgery (including ocular laser surgery) during the course of the study.
  • Prior invasive therapy for presbyopia (e.g., ciliary body electrostimulation, corneal implants).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Mean Change From Baseline in Binocular Distance Corrected Near Visual Acuity (DCNVA)
Time Frame: At Month 2
Analysis of Change from Baseline at Month 2 was done using Bayesian Approach Analysis Population.
At Month 2

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Mean Change From Baseline in Study Eye Distance Corrected Near Visual Acuity (DCNVA) at Month 2
Time Frame: Month 2
Summary of Early Treatment Diabetic Retinopathy Study (ETDRS) Letters and Change from Baseline by Analysis Visit.
Month 2
Percentage of Participants Who Improved 1/2/3-lines or More in Study Eye and Binocular Distance Corrected Near Visual Acuity (DCNVA) at Month 2
Time Frame: Month 2
The response rate is the percentage of participants that achieved the specified gain in Distance Corrected Intermediate Visual Acuity (DCIVA) without losing more than 5 ETDRS (Early Treatment Diabetic Retinopathy Study) letters in Best Corrected Distance Visual Acuity (BCDVA)
Month 2
Mean Change From Baseline in Quality of Life Assessed With Near Activity Visual Questionnaire (NAVQ) at Month 2
Time Frame: Month 2

Analysis of change from baseline in Rasch Score was done using Mixed-Effects Model for Repeated Measures (MMRM). Least Square Means were obtained by fitting a MMRM model to the NAVQ values.

The summated NAVQ score from initial 10 questions ranged from 0 to 30, where higher score indicates more difficulty with near tasks. The summated NAVQ score is converted to Rasch score which ranged from 0 to 100, with higher values indicating more difficulty with near tasks.
Month 2
Subject Treatment Satisfaction as Assessed by Patient Global Rating of Treatment
Time Frame: Month 2
The response rate is the percent of participants that responded with "Satisfactory" or "Very Satisfactory" when asked to rate the overall satisfaction with the treatment.
