Study summary

The objective of this clinical study is to evaluate the safety and efficacy of NCX 470 Ophthalmic Solution in lowering intraocular pressure (IOP) in patients with ocular hypertension or open-angle glaucoma. In the adaptive dose selection phase of the trial, subjects will be randomized in a 1:1:1 ratio to one of two doses of NCX 470 (0.065% or 0.1%) or to latanoprost 0.005%. Following the selection of one dose of NCX 470, subjects will be randomized in a 1:1 ratio to the chosen dose of NCX 470 or to latanoprost 0.005%.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Diagnosis of open-angle glaucoma or ocular hypertension in both eyes
  • Qualifying IOP at 3 time points through the day at 2 visits following washout of IOP-lowering medication, if applicable
  • Qualifying best-corrected visual acuity in each eye
  • Ability to provide and follow study instructions

Exclusion criteria

Exclusion Criteria:

  • Narrow anterior chamber angles or disqualifying corneal thickness in either eye
  • ocular disease in either eye
  • Previous complicated surgery or certain types of glaucoma surgery in either eye
  • Incisional ocular surgery or severe trauma in either eye within the past 6 months
  • Uncontrolled systemic disease
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

What researchers measure

Primary outcomes

  1. Mean IOP Reduction From Time-Matched Baseline at the 8AM and 4PM Time-Points at Week 2, Week 6, and Month 3

    The analysis performed as part of the Adaptive Dose Phase of the study was to evaluate the efficacy and safety of both concentrations of NCX 470 compared to Latanoprost. The primary endpoint for the interim analysis was mean diurnal IOP. Subsequent to the interim analysis at Week 2, the NCX 470 0.065% arm was discontinued and the primary analysis only included NCX 470 0.1% vs Latanoprost. The primary efficacy outcome results are reported for the NCX 470 0.1% and Latanoprost 0.005% treatment groups at Week 2, Week 6, and Month 3. As prespecified in the Statistical Analysis Plan, mean change from baseline in time-matched IOP was not calculated for the 0.065% group. The study eye was defined as the eye with the highest mean diurnal intraocular pressure (IOP) value at baseline (or right eye if both eyes had the same IOP value at baseline). The fellow eye was followed for safety.

    Time frame: Baseline, Week 2, Week 6, and Month 3

Secondary outcomes

  1. Reduction From Baseline in Mean Diurnal IOP at Week 2, Week 6, and Month 3 in the Study Eye

    Subjects in the NCX 470 0.065% treatment group were discontinued at Week 2 based upon the results of the planned, interim analysis. Subjects in the NCX 470 0.1% and Latanoprost 0.005% treatment groups continued for 3 months. Participants used medication in both eyes for 3 months with 1 eye designated as study eye at baseline. The study eye was defined as the eye with the highest mean diurnal intraocular pressure (IOP) value at baseline (or right eye if both eyes had the same IOP value at baseline).

Results

Posted May 30, 2025
Limitations and caveats
This was a robust, international trial demonstrating the safety and efficacy of NCX 470 0.1% Ophthalmic Solution. A 2nd Phase 3 trial is on-going and the sponsor expects the results of the 2nd trial to be consistent with the results of this study. While this study was only 3 months in length, the 2nd trial is a 12-month study.

Participant flow

Participants were recruited from 56 ophthalmologists' clinics in the US and 1 clinic in China. The first participant for the study was screened in June 2020 and the last participant exited the trial in September 2022.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jun 2020 to primary completion in Sep 2022, 27 months.

Results were first posted in May 2025, 2 years 8 months after primary completion. A results delay was requested in Sep 2022.

Of 47 industry-sponsored phase 3 interventional studies under Glaucoma, Open-Angle, half reached primary completion within 25 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 39. This study's 27 months is close to that.

Counting every sponsor, half of 49 studies reached it within 25 months; a quarter within 12 and three quarters within 39.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 24, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
