A Study to Compare Quality of Life and Satisfaction in Primary Immunodeficient Patients Treated With Subcutaneous Injections of Gammanorm® 165 mg/mL Administered With Two Different Delivery Devices: Injections Using Pump or Rapid Push

Each patient will receive the study treatment of Gammanorm using each of the two studied delivery devices according to the sequence randomly assigned based on a cross-over design: • pump and then syringe The use of automatic, programmable, compact pumps (such as CRONO SUPER PID) allows patients to remain mobile without interrupting their activities. Patients can infuse several sites simultaneously with infusion rates of up to 40 mL/h at 2 to 4 sites (abdomen, thighs, upper arms, lower back). Rapid and manual administration of SCIg using a syringe could therefore represent an alternative method by decreasing the duration of administration (around 10 minutes per injection at 1 or 2 sites simultaneously). The injection is self-administered by the patient. The infusion rate usually is 1 to 2 mL/min. The use of low viscosity products could facilitate injection
