What You Need to Know Before You Apply

What is the purpose of this trial?

The purpose of this study is to evaluate the safety, pharmacokinetics, and pharmacodynamics of multiple doses of VIS954 compared with placebo in healthy adult participants.

Will I have to stop taking my current medications?

The trial requires that participants stop taking any prescription or over-the-counter medications 30 days before the trial, except for certain exceptions like acetaminophen, ibuprofen, hormonal contraceptives, topical medications, vitamins, and dietary or herbal remedies.

How does the drug VIS954 differ from other drugs for this condition?

VIS954 is unique because it is being evaluated for safety in healthy subjects, which suggests it may have a novel mechanism or application compared to existing treatments. The use of standardized electroretinography in its evaluation highlights a focus on assessing potential ocular side effects, which may not be as emphasized in other treatments. ^{1 2 3 4 5}

What Are the Treatments Tested in This Trial?

Interventions

• VIS954

Trial Overview The study tests VIS954 against a placebo in healthy participants to assess its safety and how it's processed by the body (pharmacokinetics) as well as its effects on bodily functions (pharmacodynamics). The comparison aims to determine if there are any differences between multiple doses of VIS954 and an inactive substance.

How Is the Trial Designed?

Group I: VIS954 - Medium Dose Experimental Treatment 1 Intervention

VIS954 Medium Dose will be administered subcutaneously on Days 1, 15, 29, 43, 57, and 71

Group II: VIS954 - Low Dose Experimental Treatment 1 Intervention

VIS954 Low Dose will be administered subcutaneously on Days 1, 15, 29, 43, 57, and 71

Group III: VIS954 - High Dose Experimental Treatment 1 Intervention

VIS954 High Dose will be administered subcutaneously on Days 1, 15, 29, 43, 57, and 71

Group IV: Placebo Placebo Group 1 Intervention

Placebo will be administered subcutaneously on Days 1, 15, 29, 43, 57, and 71

Published Research Related to This Trial

Visual electrophysiological techniques like electroretinography (ERG) and visual evoked potentials (VEP) are valuable tools for assessing the safety and efficacy of new ophthalmic drug therapies during their development and post-marketing phases.

These techniques can objectively measure patient responses to eye medications and detect side effects from non-eye-related drugs, highlighting their importance in monitoring ocular health throughout the drug lifecycle.
