Phase 2b Pivotal Study of Izokibep in Non-infectious, Intermediate-, Posterior- or Pan-uveitis

Stopped early · Phase 2 · Has a placebo group

Conditions studied: Uveitis

In brief

Izokibep is a small protein molecule that acts as a selective, potent inhibitor of interleukin-17A, to which it binds with high affinity. This study investigates izokibep in subjects with active non-infectious, intermediate-, posterior- or pan-uveitis requiring high-dose steroids.

Who can join

Age: 18 and older, up to 75. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• General
• Subject has provided signed informed consent including consenting to comply with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.
• 18 years to 75 years of age
• Type of Subject and Disease Characteristics
• Subject is diagnosed with non-infectious intermediate-, posterior- or pan-uveitis
• Active disease defined by the presence of at least 1 of the following criteria in at least 1 eye despite treatment with stable doses of corticosteroids for at least 2 weeks prior to day 1:
• Active, inflammatory, chorioretinal and/or inflammatory retinal vascular lesion by dilated indirect ophthalmoscopy, fundus photography, fluorescein angiography (FA), and Spectral-Domain Optical Coherence Tomography (SD-OCT) to determine whether a lesion is active or inactive (the central reading center assessment using FA, fundus photography and/or SD-OCT is required to confirm eligibility prior to day 1).
• ≥ 2+ vitreous haze (National Eye Institute [NEI]/Standardization of Uveitis Nomenclature [SUN] criteria) by digital indirect ophthalmoscope and fundus photography (the central reading center assessment using fundus photography is required to confirm eligibility prior to day 1).
• Currently receiving treatment with oral corticosteroids (≥ 7.5 mg/day to ≤ 40 mg/day oral prednisone/prednisolone or corticosteroid equivalent) at a stable dose for at least 2 weeks prior to day 1.

You may not qualify if…

• Disease-related Medical Conditions
• Subject with isolated anterior uveitis
• Subject with serpiginous choroidopathy
• Subject with confirmed or suspected infectious uveitis
• Subject with corneal or lens opacity that precludes visualization of the fundus or that likely requires cataract surgery during the duration of the study
• Subject with intraocular pressure of ≥ 25 mmHg while on ≥ 2 glaucoma medications or evidence of glaucomatous optic nerve injury
• Subject with severe vitreous haze that precludes visualization of the fundus prior to first dose of study drug
• Subject has a contraindication for mydriatic eye drops OR subject cannot be dilated sufficiently well to permit good fundus visualization
• Subject with best corrected visual acuity (BCVA) < 20 letters (Early Treatment Diabetic Retinopathy Study [ETDRS]) in at least 1 eye prior to first dose of study drug
• Subject with proliferative or severe non-proliferative retinopathy or clinically significant macular edema due to diabetic retinopathy
• Subject with neovascular/wet age-related macular degeneration
• Subject with an abnormality of the vitreo-retinal interface with the potential for macular structural damage independent of the inflammatory process
• Subject with a history of active scleritis ≤ 12 months of first dose of study drug
• Other protocol defined Inclusion/Exclusion criteria may apply
