  • Research summary

    The purpose of this study is to find out about the safety, tolerability and efficacy of leniolisib for the treatment of immune dysregulation in common variable immunodeficiency (CVID). Leniolisib is an experimental drug which is not approved for the treatment of CVID by health authorities. However, leniolisib is approved in the United States, Israel and United Kingdom for the treatment of a related disease, activated phosphoinositide 3-kinase delta syndrome (APDS) in patients 12 years of age and older.

    CVID is a disease that can cause the immune system to not function properly. This can lead to an increased chance of infections, and/or problems of immune dysregulation like developing an enlarged spleen, enlarged lymph nodes, low blood cell numbers, and autoimmune and inflammatory problems of the lungs, gastrointestinal tract, or other organs. The Sponsor of this study, Pharming Technologies, B.V., is researching leniolisib as a potential new treatment for the immune dysregulation problems associated with CVID.

    Approximately 20 patients, age 12-75 years with CVID, will take part in this study at several different locations in the UK, Spain and USA.
    Patients participating in this study will be required to attend between 12 and 14 study visits over a period of up to 35 weeks. The visits will vary in duration depending on the procedures performed, with 4 of these visits conducted as telephone calls with associated local/at home blood draws.
