View original scientific description
The purpose of this pilot study is to evaluate the safety and efficacy of radiation therapy (RT) in the treatment of unresected keloids.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Clinically diagnosed keloid
- Surgical excision of keloid is either contraindicated or patient has declined treatment with surgical excision (Note: patients with keloids that recurred after previous resection are eligible, as long as the current keloid is either unresectable or patient has declined resection)
- Study specific informed consent provided
Exclusion criteria
- Prior RT to the area of interest that would result in overlap of radiation therapy fields
- Females of child bearing age without a negative serum pregnancy test prior to initiation of RT or unwilling to use contraception prior to and during the radiation course
- Keloids in areas where radiation therapy introduces unacceptable high risk of toxicity as determined by the treating radiation oncologist
- Uncontrolled intercurrent illness (e.g. symptomatic congestive heart failure, uncontrolled cardiac arrhythmia, or psychiatric situation) that would limit compliance with study requirements as judged by the treatment physicians
Where
- The Bronx, New York
Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
