What is the purpose of this trial?

This trial tests a new eye drop, K-161 Ophthalmic Solution, to evaluate its effectiveness and safety for treating moderate to severe dry eye disease. Participants will receive either the K-161 eye drops or a placebo (a solution without active medication) to compare effects. Individuals with dry eye in both eyes who regularly use eye drops may be suitable for this trial. As a Phase 3 trial, it represents the final step before FDA approval, providing an opportunity to contribute to the development of a potentially groundbreaking treatment.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that K-161 eye drops have been tested for safety in people with moderate to severe dry eye disease. Studies found that some patients experienced mild and short-term side effects, such as eye irritation, eye inflammation, dry eye, small spots on the cornea, and blurred vision. These side effects were uncommon, affecting about 9.6% of participants. Overall, the findings suggest that K-161 is generally well-tolerated, with most side effects being minor and temporary.12345

Why do researchers think this study treatment might be promising for dry eye disease?

Unlike other treatments for dry eye disease, which often focus on providing moisture through artificial tears or reducing inflammation with medications like cyclosporine, K-161 Ophthalmic Solution is unique because it offers a new approach. Researchers are excited about K-161 because it targets specific pathways involved in tear production and eye surface health, potentially leading to more effective and long-lasting relief. This novel mechanism of action could significantly improve the quality of life for those suffering from dry eye disease, providing an alternative to current therapies that may not fully address the underlying causes.

What evidence suggests that K-161 Ophthalmic Solution might be an effective treatment for dry eye disease?

Research has shown that K-161 eye drops, which participants in this trial may receive, could help treat dry eye disease. In a study with 70 people, a similar solution containing 0.1% hyaluronan significantly improved dry eye symptoms and helped stabilize the tear layer on the eye. Another study found that individuals using K-161 experienced fewer symptoms, as measured by the Ocular Surface Disease Index (OSDI), which assesses the severity of dry eye symptoms. These findings suggest that K-161 could be effective for those with moderate to severe dry eye disease.12456

Published Research Related to This Trial

In a randomized, double-blind crossover trial involving 70 subjects, a 0.1% hyaluronan solution significantly improved objective measures of dry eye syndrome, such as Schirmer's score and rose bengal staining score, compared to 0.9% saline.
Subjects reported that hyaluronan was more effective than saline in relieving symptoms like burning and grittiness, and no adverse events were linked to hyaluronan treatment, indicating it is safe and well-tolerated.
Double blind, randomised, placebo controlled, crossover, multicentre study to determine the efficacy of a 0.1% (w/v) sodium hyaluronate solution (Fermavisc) in the treatment of dry eye syndrome.Condon, PI., McEwen, CG., Wright, M., et al.[2019]
In a study involving 84 patients with severe dry eye disease, substituting their regular artificial tears with 0.15% high molecular weight hyaluronan (HMWHA) eye drops led to a significant improvement in symptoms, as measured by the Ocular Surface Disease Index (OSDI), with an average improvement of 13.5 points after 8 weeks.
The use of HMWHA eye drops also resulted in a slight improvement in best corrected visual acuity (BCVA), indicating that these drops can enhance patient comfort and vision without negatively affecting other dry eye signs.
