Brief Summary:

The goal of the current study is to evaluate the ability of CGB-400, a proprietary eutectic mixture of GRAS compounds, to clear the toenail fungal growth and improve the appearance of the fungus affected area(s).

This is an open-label, single group POC study evaluating the effectiveness of CGB-400 Topical Gel for toenail fungal growth clearing. The study consists of a 12-week period with 5 clinic visits at the following timepoints: Baseline (Day 0), and Weeks 2, 6, and 12 and post-application follow-up at Week 24. The applications could be extended for an additional 12 weeks based on PI's observations.

Approximately 15 subjects will be enrolled and subjected to application of CGB-400 Topical Gel. Subjects must be at least 18 years of age and will be selected by the concerned PI.

Group/Cohort Intervention/treatment
Treatment group
Only one treatment group (CGB-400 Topical Gel) will be used for analysis
Drug: CGB-400 Topical Gel
CGB-400 Gel contains two main ingredients: geranic acid and choline. Geranic acid, a naturally occurring essential oil/terpenoid, is a key ingredient in lemon grass and is also found in other natural materials such as cardamom. The other main ingredient in CAGE is choline, which is an essential dietary component and found in foods as free choline and as several esterified forms such as phosphocholine and phosphatidylcholine.
Other Name: CGB-400C Gel

Primary Outcome Measures :
  1. Investigator Global Assessment (IGA) of affected toenails [ Time Frame: 24 weeks ]

    Clear 0% nail involvement

    1. Almost clear 0%-≤10% nail involvement
    2. Mild 10%-<25% nail involvement
    3. Moderate 25%-≤50% nail involvement
    4. Severe >50%-≤75% nail involvement

Secondary Outcome Measures :
  1. Percent clear area on affected toenail/region (s) [ Time Frame: 24 weeks ]

    *Clear nail is defined as area from proximal nail fold till most proximal area of abnormality with evidence of persistent clear growth.

    Clearance must be progressively observed over two time points.

  2. Visual inspection (pictures to be collected) [ Time Frame: 24 weeks ]
    Visual inspection for application site reactions: performed at each visit along with images taken by subjects and at the time of clinic visit

Other Outcome Measures:
  1. Subject Global Assessment [ Time Frame: 24 weeks ]

    The Subject Global Assessment will be collected in the form "subject questionnaire"


    The Investigator (or designate) will ask the following questions at the Baseline visit and subject's answers will be recorded:

    1. How frequently do you typically experience fungal growth each month?
    2. How do you rate your fungal growth today relative to other times?
    3. Are you aware of specific triggers that aggravate fungal growth?
    4. How do you deal with or treat fungal growth?
    5. What other products have you tried in the past for managing/treating fungal growth?
    6. Are there any other aspects of fungal growth or experience that we should know about?
