ClinConnect Summary

This clinical trial is investigating a new treatment for a type of skin cancer called mycosis fungoides, which is a form of cutaneous T-cell lymphoma. The treatment involves using a special ointment called synthetic hypericin (also known as HyBryte) along with exposure to visible light. The study aims to see how effective this combination is for patients over a period of up to 12 months.

To participate, individuals must have a confirmed diagnosis of mycosis fungoides at certain early stages (Stage 1A, 1B, or 2A) and be between the ages of 65 and 74. They should also be willing to follow the treatment plan and provide written consent. It's important for female participants to not be pregnant or nursing and to agree to use birth control during the study. Participants will receive regular treatment and monitoring throughout the trial, and the study is currently recruiting volunteers. If you or a loved one are interested in this study, it’s a good idea to discuss it with a healthcare provider to understand more about the eligibility and what participation entails.

Stage 1B: Patches, papules, and/or plaques cover 10% or more of the skin surface. Stage 2A: Patches, papules, and/or plaques cover any amount of skin surface. Lymph nodes are abnormal, but they are not cancerous.)
