Active clinical trials for "Keratoconjunctivitis Sicca"

Severe dry eye is a debilitating ocular disease resulting in loss of vision, reduced day-to-day function and significant discomfort. Tear substitutes are an important part of the treatment of all patients, however, even with aggressive us, the corneal(ocular)surface often remains very irregular due to poor surface healing. The agent being evaluated in this study, Thymosin Beta 4, promotes healing of the corneal surface and has been studied in patients with recalcitrant corneal ulcers and erosions with significant success (Arch Ophthalmol. 2010;128(5):636-638., Ann of the NY Acad of Sci, May, 2010). The study hypothesis is that Thymosin Beta 4, in its role as a modulator of corneal surface healing, may be able to promote healing of the corneal surface allowing for more conventional modalities to take over and maintain a smooth and regular ocular surface. The investigators hope to be able to demonstrate an improvement in visual acuity, surface healing and a reduction in dry-eye related symptoms.

Primary Sjögren syndrome is one of the most prevalent autoimmune diseases that present with dry eye and dry mouth. But there is no proven effective treatment for Sjögren syndrome patient. The relation between toll-like receptor (TLR) and the pathogenesis of Sjögren syndrome has been reported. Hydroxychloroquine is TLR7 and TLR9 antagonist. A few studies have been reported the effectiveness of Hydroxychloroquine for Sjögren syndrome but no randomized controlled study has been done. So the investigators evaluate the effectiveness and safeness of Hydroxychloroquine for primary Sjögren syndrome by randomized controlled study (Hydroxychloroquine 300 mg once daily p.o. group (N = 30) versus placebo group (N = 30).

The objective of this study is to compare the safety and efficacy of 1% MIM-D3 and 5% MIM-D3 to placebo for the treatment of the signs and symptoms of dry eye.

The purpose of this study is to evaluate the efficacy of Optive versus Systane used concomitantly with topical cyclosporine for the treatment of dry eye.

The purpose of this trial is to assess the effectiveness and safety of 2% diquafosol tetrasodium ophthalmic solution versus placebo following 6 weeks of treatment in subjects with mild to moderate dry eye disease.

The primary purpose of the study is to determine whether B-cell depletion with Rituximab has an effect on the oral, ocular and general disease manifestations in patients with primary Sjögren´s syndrome, that is, an effect on the symptoms of oral and ocular dryness, improvement of the glandular function and a beneficial effect on the general symptoms such as fatigue. The secondary purpose of the study is the investigate the underlying autoimmune and pathophysiological mechanisms in Sjögren´s syndrome.

The purpose of the study is to evaluate dose-response, efficacy and safety of CP-690,550 eye drops in patients with dry eye disease.

The objective of this study is to compare the safety and efficacy of azithromycin ophthalmic solution, 1% in dry eye subjects over a four week treatment period, using placebo as a comparison.

The purpose of this study is to evaluate the safety and efficacy of rebamipide 2% suspension for the treatment of patients with dry-eye.

The purpose of this study is to evaluate safety and efficacy of OPC-12759 ophthalmic suspension during 52 weeks in dry eye patients
