About laquinimod

Laquinimod is a first-in-class immunomodulator that induces immune tolerance and reduces the proinflammatory and angiogenic response by targeting of the myeloid cell compartment. Laquinimod is developed as a new treatment for inflammatory eye disorders in the first step non-infectious uveitis. Laquinimod was previously studied in patients with neurodegenerative and inflammatory diseases, including a phase III randomized study program in multiple sclerosis (MS) patients. The clinical safety and tolerability of laquinimod is well known and preclinical data in disease models support the use of laquinimod for treatment of severe eye disorder including uveitis and eye disorders with abnormal vascularization.
