Frequently Asked Questions
What are Clinically Significant Angiokeratomas ?
Clinically Significant Angiokeratomas are a type of vascular malformation caused by enlarged blood/lymphathic vessels close to the surface of the skin.
Angiokeratomas are usually dark red, purple, or black in color and may appear raised or rough on the skin. They can become painful, bleed easily, or grow in areas that are irritated by clothing or movement and may affect comfort, daily activities, or quality of life.lymphatic
What is a clinical trial?
A clinical trial, sometimes called a “study,” is the investigation of a medicine in a new way. Sometimes the medicine has been studied and approved for other diseases. Clinical trials in the United States are closely regulated by the Food & Drug Administration (FDA). Study participants and their doctors are provided with information specific to the trial to help them make a decision about whether the study is right for them.
What is the medicine being tested?
All patients in the LOTU Trial will treat themselves at home with a new gel formulation of an approved drug (rapamycin, also known as sirolimus). The gel will be rubbed onto the skin once a day by the participant, or for very young children, by their caregiver.
How much will participants be compensated for participating in the study?
Compensation is offered to offset patient burden and should not be considered the reason for participation. If you or your child is a good match for the study, the details related to the study stipend will be provided to you.
What if I don't see a location near me?
The study sponsor will pay travel expenses to a study location that is convenient for both the participant and one caregiver.
