Easing the study enrollment process

To enable easier access to the clinical trial for children and their families, 25 locations for The TAPESTRY Study are planned across the United States, Australia and New Zealand.

Eligible participants will be randomly assigned to receive AB-2004 or placebo and all study-related assessments at no cost. Expenses for travel to and from the doctor and medical visits will be paid for by Axial Therapeutics. Additional information around travel reimbursement will be provided by the trial coordinator.
