Brief Summary

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

Treatment of keloids with targeted Ultraviolet-Beta (UVB) radiation will improve the clinical appearance and induration of lesions.

Study Groups

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

Treatment Group

Keloids that were randomized to the treatment group, were exposed to Narrowband-UVB (NB-UVB). Targeted UVB will be delivered to the keloid for up to 16 weeks using the Lumera UVB light phototherapy device (Daavlin, Bryan Ohio, USA).The affected skin will be irradiated using a hand-held fiber optic cable with an adjustable aperture.

Group Type EXPERIMENTAL

NB-UVB

Intervention Type DEVICE

NB-UVB has an emission spectrum in the ultraviolet B range of 290-320 nm. The system consists of a light source, a spot handpiece, and a light guide that connects the handpiece to the light source. The light source has a Start/Stop switch for light beam activation. Activation can also be controlled remotely with a foot switch. The light source has a timer and an output level control to adjust the intensity of the ultraviolet light. This will be calibrated using a manufacturer-provided UV meter prior to every treatment to ensure accurate doses of ultraviolet light.

Control Group

Keloids that were randomized to a non treatment group, were not exposed to the NB-UVB light.

Group Type NO_INTERVENTION
