Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a single-center, double-blind, randomized, 2 period cross-over study to be conducted in 18 subjects (18 years of age and above) each of whom will receive SB204 8% and Vehicle Gel. Subjects who satisfy the entry criteria will be randomized to SB204 8% or Vehicle Gel in a 1:1 ratio for the first treatment period. Study drug will be applied to the face, upper chest, upper back and shoulders (approximately 17% BSA) twice daily on Days 1- 4 approximately 12 hours apart. On Day 5, the study drug will be applied to the same areas only once, in the morning. Pharmacokinetic (PK) profiling will be performed on Day 1 and Day 5. After a wash out period, subjects will be treated with the alternate product and undergo similar treatment and assessments. The primary assessment is the pharmacokinetic profile of nitrate and silicon as markers for systemic exposure to nitric oxide (nitrate) and NVN1000 (silicon) after topical application of SB204 8% to approximately 17% of the total body surface area.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Pharmacokinetics of nitrate and silicon
Time Frame: After single dose and multiple dose (Day 5) application
Standard PK parameters including area under the curve (AUC) 0-∞, AUC0-t, Cmax, Cmin, and T1/2, for nitrate and silicon. Calculations may be based on actual and/or baseline-subtracted concentrations for nitrate.
After single dose and multiple dose (Day 5) application

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Safety
Time Frame: Safety will be assessed throughout the study duration (up to 7 weeks).
Physical examinations including vital signs, EKGs, and laboratory assessments (serum chemistry, hematology and urinalysis) will be performed at Screening and during the study. Adverse events will be collected throughout the study.
Safety will be assessed throughout the study duration (up to 7 weeks).

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Tolerability
Time Frame: During both treatment periods, through last day of treatment.
During the study, cutaneous tolerability assessments will be made at Day 1 and at the end of each treatment period (Day 5). Erythema, dryness, scaling, stinging/burning and itching will be assessed on a four point scale where 0 = none, 1 = mild, 2 = moderate, and 3 = severe.
During both treatment periods, through last day of treatment.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
