Topical Absorption of Glutathione-cyclodextrin Complex in Healthy Human Subjects Improves Immune Response Against Mycobacterium Infection

Phase 1

Completed

• Conditions: Glutathione-cyclodextrin Complex Absorption
• Interventions: Dietary Supplement: Placebo Solution; Dietary Supplement: Glutaryl Solution

• Registration Number: NCT05926245
• Lead Sponsor: Western University of Health Sciences

Brief Summary

The proposed clinical trial will confirm the therapeutic absorption of glutathione following topical Glutaryl application in increasing blood GSH levels without an invasive procedure.

GOAL: Confirm therapeutic level of glutathione following topical transdermal application.

HYPOTHESIS: The hypothesis of the proposed study is that the glutathione administration will increase RBC levels of glutathione above 80%.

AIM: Determine a non-invasive way to increase glutathione levels in the plasma and blood cells.

This aim will be accomplished as follows:

STEP 1: We will recruit eligible healthy participants in the two study groups who are not currently taking any glutathione or N-acetyl cysteine (NAC) supplementation.

STEP 2: Determine baseline levels of GSH, free radicals and cytokines through analysis of venipuncture blood draws.

STEP 3: Study subjects will be asked to spray themselves with either placebo or Glutaryl four times twice a day for three days on the ventral part of the abdomen. Measure the levels of GSH, free radicals and cytokines after 1 hour, 4 hour and 72 hours.

Recruitment & Eligibility

• Status: COMPLETED
• Sex: All
• Target Recruitment: 30

Inclusion Criteria

• Group 1 (Control group) will include 15 healthy volunteers with the age group between 21-65. Participants belonging to Group 1 will be recruited from the local area. Group 1 will serve as controls for Group 2.

Group 2 (Glutathione Group) will include 15 healthy volunteers that are not allergic to any components of GlutarylTM who will be sprayed four times twice a day for three days with Topical glutathione Complex (GlutarylTM) formulation on their skin on their ventral part of the abdomen.

Components of Glutaryl:

Main ingredients of Glutaryl are Glutathione, ascorbic acid and cyclodextrin. The preservative system used is potassium sorbate and radish root extracts.

Exclusion Criteria

• Pregnant and breastfeeding women. Anyone below age of 21 or above age of 65. Patients with active cancer. Patients with known liver disease, hepatitis, COVD-19, HIV, or AIDS. Patients taking some form of glutathione. Subjects who have previously fainted following venipuncture will also be excluded. By interviewing the subjects we will determine whether or not the subject will be excluded from the study based on their previous phlebotomy experiences.

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: PARALLEL

Arm && Interventions

Group	Intervention	Description
Placebo Group	Placebo Solution	15 adult healthy volunteers to serve as controls for the experimental group. This group will receive a placebo-topical spray with empty nanoparticles.
Glutathione Group	Glutaryl Solution	15 adult healthy volunteers will serve in the experimental group. This group will receive glutaryl treatment topical spray with nanoparticles containing GSH.

Primary Outcome Measures

Name	Time	Method
GSH	72 hours	Levels of total, reduced, and oxidized forms of GSH in the isolated plasma, red blood cells (RBCs) and peripheral blood mononuclear cells (PBMCs) isolated from the peripheral blood of the two-study groups will be assayed by spectrophotometry using an assay kit from Arbor Assays (3-12).

Secondary Outcome Measures

Name	Time	Method
Pro- and Anti-inflammatory Cytokines	72 hours	To demonstrate that increased levels of GSH in the experimental group is accompanied by altered levels of pro- and anti-inflammatory cytokines and chemokines, we will measure the levels of pro- and anti-inflammatory cytokines and cytokines in the plasma derived from the two study groups by ELISA using an assay kit from ThermoFisher.
Free Radicals	72 hours	To demonstrate that increased levels of GSH in the experimental group is accompanied by decreased levels of reactive oxygen species (ROS), free radical activity will be measured by malondialdehyde (MDA) assay that measures several end products of lipid peroxidation (3-12).
