Study summary

This is a multi-center, randomized, double-masked, placebo-controlled, Phase 2 study evaluating the safety and tolerability of NCX 4251 (fluticasone propionate nanocrystal) Ophthalmic Suspension 0.1% QD and BID for the treatment of acute exacerbations of blepharitis. The study will be performed in two sequential dose escalating cohorts.

The study is designed to select the dose(s) of NCX 4251 to advance into the next stage of development, and to assess the safety and tolerability of NCX 4251 Ophthalmic Suspension.

Inclusion criteria

  • history of blepharitis and meet qualifying criteria for an acute exacerbation of blepharitis in both eyes at Screening and Baseline/Day 1 Visits
  • have a qualifying best-corrected visual acuity

Exclusion criteria

Exclusion Criteria:

  • abnormality of the eyelids or lashes (other than blepharitis), or previous eyelid surgery
  • IOP > 21 mmHg at Screening or Baseline/Day 1 Visits
  • use of in the past 30 days or retinoids in the past 12 months
  • uncontrolled systemic disease
Terms in these criteria, in plain language(1)

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.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

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 18, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
