What the trials found For clinicians

Common Variable Immunodeficiency: what the trials found

Clinical evaluations of various immunoglobulin treatments for Common Variable Immunodeficiency have established specific safety and efficacy profiles. Gammaplex was associated with a statistically significant incidence of adverse events (p=0.01) in a Phase 4 study 1. Additionally, trials were conducted evaluating the use of Gammaplex (5%) 3 and Subgam 4.

Data regarding patient outcomes for intravenous and subcutaneous immunoglobulin therapies indicate specific metrics for morbidity. Patients receiving Human Immunoglobulins Intravenous reported an average of 8.5 days out of work/school due to illness and 0.0 days of hospitalization 5. For patients receiving Human Normal Immunoglobulin for Subcutaneous Administration (IGSC), the annual rate was 8.00 days out of work/school and 3.48 days of hospitalization due to infections 6.

Quality of life assessments were conducted using standardized tools in a Phase 4 study involving Vivaglobin. Results for the SF-36 (Age ≥ 14 Years) ranged from 54.40 to 80.00, while results for the CHQ-PF50 (Age ≤ 13 Years) ranged from 74.06 to 100.00 2.

Recent results — preliminary, needs further review

  • A Phase 2 trial of Thiotepa (single daily dose) reported 0% graft rejection/failure and 100% survival at 24 months post-transplant, though these findings are not yet corroborated 7.

For the clinician treating this condition

  • Immunoglobulin therapies show measurable impacts on patient activity; intravenous administration was associated with 8.5 days out of work/school and 0.0 hospitalizations 5.
  • Subcutaneous administration (IGSC) resulted in an annual rate of 8.00 days out of work/school and 3.48 days of hospitalization due to infections 6.
  • Gammaplex was associated with a statistically significant rate of adverse events (p=0.01) 1.
