Study summary

This is a multi-center, randomized, double-masked, proof-of-concept study in patients with Active Noninfectious Intermediate, Posterior, or Panuveitis.

Read the detailed description

This study will consist of a 2-week screening period (+7 days), 24-week treatment period, followed by a 24-week extension period, and a 4-week follow up period for a total of up to 55 weeks. Each participant will be randomized to receive one of two doses of ESK-001 daily for 24 weeks. Participants that do not meet the treatment failure criteria at Week 24 will continue into the extension period.

What researchers measure

Primary outcomes

  1. To compare the efficacy between 2 ESK-001 treatment groups for the treatment of active NIU as measured by the proportion of patients failing treatment by Week 24

    The proportion of patients failing treatment for active NIU by Week 24 between 2 ESK-001 treatment groups. Treatment failure is defined as a patient meeting at least 1 of the treatment failure criteria in at least 1 eye at Week 24.

    Time frame: 24 Weeks

Secondary outcomes

  1. To compare the efficacy between 2 ESK-001 treatment groups for the treatment of active NIU as measured by the time to treatment failure on or after Week 24

    Time to treatment failure on or after Week 24 between 2 ESK-001 treatment groups. Time to treatment failure is defined as time to the visit of the first treatment failure as defined per protocol. Median time to treatment failure in each treatment group will be reported and compared.

    Time frame: 24 Weeks

  2. To assess the safety and tolerability of ESK-001 in patients with active NIU by comparing the incidence and proportion of treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs).

    Clinical and laboratory assessments including blood tests, ECGs, hematological measures and physical examinations throughout the study. The number and proportion of TEAEs, SAEs, AEs leading to study discontinuation, and AEs of greater than grade 3 severity will recorded per treatment group and across all groups.

    Time frame: Through study completion, up to 52 weeks

  3. To characterize the pharmacokinetics (PK) of ESK-001 (Cmax)

    Plasma concentrations and PK parameters including steady-state maximum observed concentration (Cmax) for ESK-001 at Day 1, Week 24, and Week 48.

    Time frame: Through study completion, up to 48 weeks

  4. To characterize the pharmacokinetics (PK) of ESK-001 (Ctrough)

    Plasma concentrations and PK parameters including steady-state trough observed plasma concentration (Ctrough) for ESK-001 at Week 24, and Week 48.

    Time frame: Through study completion, up to 48 weeks

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 Aug 28, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
