入选标准

  • Diagnosis of ADA-deficient combined immunodeficiency
  • Stable clinical status while receiving therapy with Adagen®. Patients previously receiving gene therapy or undergoing hematopoietic stem cell transplantation who still require Adagen® treatment are eligible. The dose of Adagen® must be stable for at least 6 months prior to study entry.
  • Have both of the following during the Adagen® Lead-in phase of the study prior to EZN-2279 transition:
  • Trough plasma ADA activity >15 μmol/h/mL while receiving Adagen® and
  • Total erythrocyte dAXP ≤0.02 μmol/mL from a trough blood sample
  • Patients or parent/guardian must be capable of understanding the protocol requirements and risks and providing written informed assent/consent

排除标准

  • Autoimmunity requiring immunosuppressive treatment
  • Patients with detectable neutralizing anti-Adagen® antibodies at screening evaluation
  • Severe thrombocytopenia (platelet count <50 x 10^9/L)
  • Current participation in other therapeutic protocols for ADA-deficient combined immunodeficiency
  • Current or prior participation in another clinical study with an investigational agent and/or use of an investigational drug in the 30 days before study entry
  • Known planned participation in a gene-therapy study for the planned duration of this study
  • Any condition that, in the opinion of the PI, makes the patient unsuitable for the study
  • Inability or unwillingness to administer Adagen® or EZN-2279 on a one-time-per-week regimen
  • Inability to comply with the study protocol
  • Female patients who are pregnant or lactating
  • Female patients who are breast-feeding
  • Female subjects of childbearing potential who are not using an FDA approved birth control method
