Outcomes

Primary Outcome Measures

Adverse events
Type, frequency, seriousness, severity and relationship to treatment

Secondary Outcome Measures

Participant-reported eye-toxicities
Assessed from change from baseline in ocular symptoms score determined using a Visual Analogue Scale with 0-100 range, where 0= no symptom and 100= worst possible discomfort.
Investigator-reported eye-toxicities - BCVA
Assessed from change from baseline in Best Corrected Visual Acuity (BCVA) using the Early Treatment Diabetic Retinopathy Study research group (ETDRS) visual acuity chart with objective and subjective refraction.
Investigator-reported eye-toxicities - Slit lamp examination
Assessed from change from baseline in slit lamp examination parameters (eyelid swelling, eyelid redness, conjunctival redness, conjunctival chemosis, scleral redness, corneal opacity, iris alterations and anterior chamber flare) graded on a 4-point scale where 0= none, 1= mild, 2= moderate, and 3= severe.
Investigator-reported eye-toxicities - Corneal fluorescein staining
Assessed from change from baseline in corneal fluorescein staining determined using the NEI/Industry Workshop guidelines. The cornea is divided into five sectors (central, superior, inferior, nasal and temporal) and each sector scored on a 4-point scale, where 0= no staining and 3= maximum staining.
Investigator-reported eye-toxicities - Intraocular pressure
Assessed from change from baseline in intraocular pressure (mmHg) determined using a Goldmann applanation tonometer.
Investigator-reported eye-toxicities - Funduscopy in mydriasis
Assessed from change from baseline in clinical signs detected by indirect funduscopic inspection of the optic disc, macula, retinal vessels and retinal periphery.
Peak plasma concentration of laquinimod
Maximal plasma concentration (Cmax) of laquinimod as assessed from samples collected pre-dose and at frequent intervals over 7 days after (last) dose
Time to peak plasma concentration of laquinimod
Time to maximal plasma concentration (tmax) of laquinimod as assessed from samples collected pre-dose and at frequent intervals over 7 days after (last) dose
Trough plasma concentration of laquinimod at steady-state
Minimal plasma concentration (Cmin,ss) of laquinimod as assessed from samples collected pre-dose on Days 12, 13 and 14 within the multiple-dose arm
Systemic exposure of laquinimod
Area under the plasma concentration time curve (AUC) of laquinimod

5. Study Description

Brief Summary
This is a Phase 1 randomized, double-masked, placebo-controlled study performed with healthy participants to assess the safety and tolerability of laquinimod eye-drops.
Detailed Description
Laquinimod administered as an oral capsule formulation has previously been studied in neurodegenerative and autoimmune diseases. The clinical side effect profile of orally administered laquinimod is well-characterized based on this previous experience. This trial will establish a safe and tolerated dose of laquinimod when administered as an eye-drop formulation following single ascending dose (SAD) and multiple ascending dose (MAD) administrations. There are four planned groups in the SAD-part of the study which will enroll 28 participants, if all dose levels are explored. The subsequent MAD-part of the study will enroll another 28 participants.
