Summary

This trial tests a special gel called SM-020 on people with small, dark skin bumps known as Dermatosis Papulosa Nigra (DPN). Participants will use the gel regularly for several weeks and be monitored over a few months to see if the gel is safe and effective.

Who is the study for?
Adults over 18 with Dermatosis Papulosa Nigra (DPN), specifically those with skin types 4, 5, or 6. Participants must have at least five but no more than ten eligible DPN lesions on the face that are not inflamed or covered by hair and are between 2mm to 5mm in diameter. Pregnant women, individuals using certain medications like immunosuppressives or photosensitizers, and those with a history of skin cancer near the lesions cannot participate.
What is being tested?
The trial is testing SM-020 gel at a concentration of 1.0% for safety and effectiveness in treating DPN. Around ten participants will apply this gel twice daily for four weeks to up to ten selected facial lesions. They'll be monitored for twelve additional weeks after treatment ends.
What are the potential side effects?
While specific side effects aren't listed here, potential risks may include local skin reactions such as irritation, redness, itching or burning sensation where the gel is applied due to sensitivity to its ingredients.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Common treatments for Dermatosis Papulosa Nigra (DPN) often involve topical agents that work through mechanisms such as keratolysis, which helps in the shedding of the outer skin layer, anti-inflammatory effects to reduce skin irritation, and inhibition of melanin production to lighten the lesions. For instance, the investigational SM-020 gel 1.0% being studied aims to target DPN lesions by potentially combining these mechanisms to effectively reduce the size and appearance of the lesions. Understanding these mechanisms is important for patients as it provides insight into how the treatment works and what outcomes they can anticipate.
