The 4WHIM Trial is a phase 3 clinical research study now enrolling people living with WHIM syndrome to see if mavorixafor, an investigational treatment, can lower
infections and warts
WHIM syndrome is a rare and difficult-to-diagnose primary immunodeficiency in which the body’s immune system does not function properly and has trouble fighting infections. Some doctors also call primary immunodeficiencies inborn errors of immunity, which are genetic mutations that cause immunodeficiencies. WHIM syndrome is caused by mutations in the CXCR4 gene which causes white blood cells to get trapped in the bone marrow.
WHIM syndrome was named after four symptoms that most diagnosed patients have experienced: Warts, Hypogammaglobulinemia, Infections, Myelokathexis. There are no existing treatments that specifically target the underlying problem of WHIM syndrome—new treatments are needed.
The goals of the new phase 3 study are to find out if the investigational oral drug mavorixafor can safely reduce bacterial infections and warts in people with WHIM syndrome.
The 4WHIM Trial is a phase 3, randomized, double-blind, placebo-controlled study in patients with WHIM syndrome with an open-label extension study.
Researchers learned in phase 1 and phase 2 studies that mavorixafor may help people with WHIM syndrome by targeting the way the disease manifests.
Talk to your doctor to see if joining a clinical trial is a good option for you.
The study is now enrolling up to 28 people who meet the following criteria.
Additional criteria will need to be met and can be discussed with your doctor. There is no cost to participate in the trial.
All study participants will have an opportunity to receive 400 mg of mavorixafor until it is commercially available, or the study ends. This is called an open-label extension study. The results will be shared.
The 4WHIM Trial is being conducted at multiple medical centers around the world. Study sites are now open in the U.S. and now enrolling volunteers who are living with WHIM syndrome.
You do not need to live near a study site to participate in the 4WHIM Trial. If you need to travel to a study site, the study sponsor, X4 Pharmaceuticals, will pay for travel and lodging. Also, for some study participants, visits can occur at home through video calls and home visits.
