Disease: Autoimmune Lymphoproliferative Syndrome

Research Description: Autoimmune Lymphoproliferative Syndrome (ALPS) is a rare childhood autoimmune disease. Patients suffer from enlarged lymph nodes and spleen, increased infections and anemia. ALPS patients may spend as many as 5-10 days in the hospital each month and may not survive beyond their teens. Dr. Teachey tested the repurposed generic drug sirolimus, a drug used to prevent rejection in organ transplants, in mice. Using the results of this CWR-funded mouse study, he then conducted a pilot clinical study among six patients at the Children’s Hospital of Philadelphia, in which five of the six patients were in complete remission in 90 days. Patient hospitalizations declined, and patients have continued to survive and thrive on sirolimus. The cost to treat these patients has also significantly decreased, resulting in lower medical bills.
