What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change from baseline at week 6 in ocular itching score assessed by visual analog scale (VAS).

    The ocular itching VAS ranges from 0 to 100 mm (0 mm = no ocular itching at all, 100 mm = intolerable itching). Participants will be asked to subjectively rate the current severity of ocular itching at each time point.

    Measured: Baseline and at Week 6

Secondary outcomes (16)
  1. Change from baseline at week 6 in corneal epithelial fluorescein staining, scored by modified Oxford scale, in the study eye.

    Fluorescein will be applied to the inferior fornix of the palpebral conjunctiva of each eye. To avoid the phenomenon of quenching, staining will be assessed within 1 to 4 minutes from fluorescein instillation. Examination will be performed at the slit-lamp using blue (cobalt) light. Corneal fluorescein staining will be graded according to the modified Oxford scale (7-point scale: 0, 0.5. 1, 2, 3, 4, 5).

    Measured: Baseline and at Week 6

  2. Change from baseline at week 6 in bulbar conjunctival hyperemia assessed by Validated Bulbar Redness (VBR) 10 scale (0 to 100), in the study eye.

    Bulbar conjunctival redness will be assessed at the slit-lamp examination using white light prior to vital dye instillation and graded according to the VBR 10 scale.

    Measured: Baseline and at Week 6

  3. Change from baseline over time in ocular itching score assessed by VAS.

    The ocular itching VAS ranges from 0 to 100 mm (0 mm = no ocular itching at all, 100 mm = intolerable itching). Participants will be asked to subjectively rate the current severity of ocular itching at each time point.

    Measured: Baseline and at Week 4, Week 6, Week 8, Week 12, and Week 16

  4. Change from baseline over time in ocular symptoms of itching, tearing, discomfort, mucous discharge, and photophobia on a 4-point scale (0 to 3).

    Ocular symptoms are assessed using a 4-point severity scale ranging from 0 (none) to 3 (severe). Five ocular symptoms, itching, tearing, ocular discomfort (including burning, stinging, and foreign body sensation), mucous discharge, and photophobia are evaluated in the study eye. A composite symptom score is described in calculated at screening and Baseline by summing the individual symptom scores, resulting in a total score range of 0 to 15, with higher scores indicating greater symptom severity.

    Measured: Baseline and at Week 4, Week 6, Week 8, Week 12, and Week 16

  5. Change from baseline over time in corneal fluorescein staining (modified Oxford scale) in the study eye.

    Corneal fluorescein staining modified Oxford scale (0-5) as per corneal dot count in each eye.

    Measured: Baseline and at Week 4, Week 6, Week 8, Week 12, and Week 16

  6. Change from baseline over time in bulbar conjunctival hyperemia assessed by VBR 10 scale (0 to 100) in the study eye.

    Bulbar conjunctival hyperemia assessed by Validated Bulbar Redness (VBR) 10 scale (0 to 100).

    Measured: Baseline and at Week 4, Week 6, Week 8, Week 12, and Week 16

  7. Change from baseline over time in signs of tarsal papillary reaction, corneal neovascularization, cicatrizing conjunctivitis and blepharitis on a 4-point scale (0 to 3) in the study eye.

    Change in signs on a 4-point scale (0 to 3) in the study eye.

    Measured: Baseline and at Week 4, Week 6, Week 8, Week 12, and Week 16

  8. Change from baseline at week 6 and 12 in the QoL scores assessed by the Standardized Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ-S) (assessed in the adult cohort only)

    Standardized Rhinoconjunctivitis QoL Questionnaire (RQLQ[S]) is a validated questionnaire that assesses QoL specifically in patients with rhinoconjunctivitis. There are 28 questions, which are categorized under 7 domains (activities, sleep, non-nose/eye symptoms, practical problems, nasal symptoms, eye symptoms, and emotional). Each question is scored on a 7-point scale from no impairment (score 0) to severe impairment (score 6).

    Measured: Baseline and at Week 6 and Week 12.

  9. Patient Global Impression of Change (PGIC) at week 6 and week 12 (assessed in the adult cohort only)

    PGIC is a short questionnaire used to assess how a participant perceives changes in their condition following treatment, on a scale ranging from 1 to 7.

    Measured: At week 6 and week 12.

  10. Number of Participants receiving rescue medication over time after week 6

    Participants who received rescued medication over time after week 6 (visit 4).

    Measured: Week 6 to Week 12

  11. Number of participants with treatment-emergent adverse events and serious adverse events (SAEs)

    Any adverse events occurring or worsening after the first administration of investigational product is classified as "treatment-emergent" adverse events and does not necessarily have a causal relationship with the intervention. A SAE is any untoward medical occurrence that at any dose results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, is a suspected transmission of any infectious agent via a medicinal product, and is medically important.

    Measured: Up to Week 16

  12. Change from baseline over time in best corrected distance visual acuity (BCDVA) in each eye.

    Best corrected visual acuity (BCDVA) is determined by careful refraction according to the standard protocol for refraction. BCDVA is measured by Early Treatment of Diabetic Retinopathy Study chart.

    Measured: Baseline and at Week 4, Week 6, Week 8, Week 12, and Week 16

  13. Change from baseline at week 12 in corneal endothelial cell density in each eye (only at selected sites that have the required equipment).

    Corneal central region endothelial cell density will be determined for each eye using specular microscopy and expressed as the number of cells/mm2 using the Cell Density readout provided by the software.

    Measured: Baseline and at week 12

  14. Change from baseline at week 12 in dilated fundus exam in each eye

    After specular microscopy, mydriatic drops will be instilled in both eyes and once adequate dilation is achieved, a fundal exam shall be performed to examine the vitreous, retina, and optic nerve.

    Measured: Baseline and at week 12

  15. Change from baseline over time in intraocular pressure in each eye.

    IOP will be assessed by tonometry for each eye and will be measured in mmHg.

    Measured: Baseline and at Week 6 and Week 12

  16. Number of participants discontinued due to tolerability during the treatment period

    Treatment discontinuation rate due to tolerability.

    Measured: Baseline to week 12
