This approval provides patients with a more flexible, less frequent dosing regimen administered once every 3–4 weeks enhancing convenience and adherence compared to traditional IVIG infusions
• In August 2024, the Immune Deficiency Foundation (IDF) showcased a breakthrough session titled “Gene Editing for X-linked Agammaglobulinemia” during its annual Primary Immunodeficiency (PI) Conference. Researchers presented progress on CRISPR/Cas9-based gene editing techniques designed to repair defective BTK genes within hematopoietic stem cells. This cutting-edge approach could potentially restore immune function in XLA patients, marking a significant evolution in rare disease therapeutics
• In March 2024, Genezen Therapeutics announced a strategic collaboration with Seattle Children’s Research Institute to advance a novel cell therapy program for X-linked agammaglobulinemia (XLA). The initiative aims to genetically modify a patient’s own stem cells to correct mutations in the BTK gene, responsible for defective B-cell development. This partnership represents a major step toward potentially curative therapies for XLA, shifting focus from lifelong immunoglobulin replacement to gene-based correction
• In June 2023, Dr. Donald Kohn of the University of California, Los Angeles (UCLA) received the Michael Blaese Research Grant from the Immune Deficiency Foundation to support the development of a CRISPR gene-editing strategy for XLA. His team is focusing on precisely inserting functional copies of the BTK gene into patient-derived hematopoietic stem cells, aiming to restore normal B-cell production. This research builds upon Kohn’s previous success in gene therapy for ADA-SCID and offers hope for a similar curative pathway for agammaglobulinemia
• In May 2023, a landmark registry study involving 240 patients with X-linked agammaglobulinemia was published in the Journal of Clinical Immunology. Conducted across the U.S., the study analyzed treatment patterns, infection frequency, and long-term outcomes. Results showed that 92% of patients were on immunoglobulin replacement therapy, with a subset also using prophylactic antibiotics
