Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The initial focus of the study will be on safety, sun protection factor (SPF) characterization, and substantivity (duration of protection) studies. The primary outcome of the study will be to measure the sun protection factor (SPF) of a bioadhesive nanoparticles (BNP) formulation in 20-25 healthy volunteers with fair skin.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of this study will be to evaluate the duration of protection and efficacy of a novel bioadhesive nanoparticle sunscreen in 20-25 human volunteers.This technology makes sunscreens safer and longer-lasting by encapsulating UV sunscreen active agents in non-toxic nanoparticles. Strong preclinical data exists demonstrating the potential for improved safety, long-duration of retention, and increased effectiveness of this product.

This innovative solution focuses on preventing damage caused by UV exposure through the use of a nanoparticle delivery vehicle. The bioadhesive feature of this technology enables longer protection. In addition, encapsulation of the UV filter in a bioadhesive nanoparticle (BNP) improves filter photo-stability, delays filter photo-degradation, and prevents reactive oxygen species (ROS) escape, thereby reducing the risk of cell damage and epidermal toxicity from UV filters.

Furthermore, the bioadhesive feature of our technology eliminates penetration into deeper skin layers or into the blood, minimizing the potential side-effects of UV filters. It is believed that the translation of this technology will provide a longer-lasting, safer, more protective UV sunscreen.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

UV Filter + BNP

A UV filtering agent and bioadhesive nanoparticles (BNPs) will comprise the experimental condition in this study. Participants will have 5 sites on their torso where they will have these placed.

Group Type EXPERIMENTAL

Standard Sunscreen

Intervention Type DRUG

Areas will be treated with a standard preparation, consisting of padimate O (7%) and oxybenzone (3%) will be used as the control sunscreen.

BNP

Intervention Type DEVICE

Additional areas will be treated with empty bioadhesive nanoparticles (BNPs).

BNP only

A placebo bioadhesive nanoparticles (BNPs) (strips with no UV filtering) will comprise the sham comparison in this study. Participants will have 5 sites on their torso where they will have these placed.

Group Type SHAM_COMPARATOR

BNP

Intervention Type DEVICE

Additional areas will be treated with empty bioadhesive nanoparticles (BNPs).

Standard

As the active comparator, participants will have 5 sites on their torso where they will have standard sunscreen applied.

Group Type ACTIVE_COMPARATOR

Standard Sunscreen

Intervention Type DRUG

Areas will be treated with a standard preparation, consisting of padimate O (7%) and oxybenzone (3%) will be used as the control sunscreen.

Control

Participants will have 5 sites on their torso where no agent will be applied.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Subjects must be in good health with minimal skin irregularities, as evaluated by a physical examination.
* The physical examination shall determine the presence of sunburn, suntan, scars, active dermal lesions, and uneven skin tones on the areas of the back to be tested. The presence of nevi, blemishes, or moles will be acceptable if in the physician's judgment they will not interfere with the study results. Excess hair on the back is acceptable if the hair is clipped or shaved.
* Subjects must fall into one of the following 3 Fitzpatrick Skin Scale categories:

1. Always burns easily; never tans (sensitive)
2. Always burns easily; tans minimally (sensitive)
3. Burns moderately; tans gradually (light brown) (normal)

Exclusion Criteria

* Volunteers cannot have a history of skin cancer (such as basal cell carcinoma, squamous cell carcinoma, or melanoma).
* Volunteers cannot have a history of skin disease (such as psoriasis, exema, or vitiligo).
