Clinical Trial Summary

The Glaucoma Nicotinamide Trial (TGNT) is a prospective, randomized, placebo-controlled double-masked clinical trial composed of two cohorts; The Swedish Glaucoma Nicotinamide Trial (SGNT) and the Vitamin B3 In Glaucoma Study (VBIGS). Patients with open-angle glaucoma (OAG) will be randomized to receive either Nicotinamide or placebo through block randomization stratified by glaucoma subtype with a 1:1 allocation.


Clinical Trial Description

The treatment arms that included patients will be randomized into are either Nicotinamide tablets 1.5g for 6 weeks and then 3.0g onwards or true placebo tablets. A major difference between the SGNT and VBIGS is that in SGNT untreated newly diagnosed glaucoma patients will be included whereas in VBIGS glaucoma patients with intraocular pressure lowering treatment will be included. Also, in SGNT an additional non-blinded arm with healthy subjects will receive Nicotinamide tablets 1.5g for 6 weeks and then 3.0g onwards. For participants where both eyes are eligible, both will be included. The primary endpoint is visual field progression change over two years. ;
