Zemaira (Alpha-1-Proteinase Inhibitor) Therapy in HIV-1 Disease
In Brief
A Phase 3 clinical trial evaluating alpha-1-Proteinase Inhibitor for HIV Disease. Completed, enrolled 4 participants across 1 site.
Detailed Summary
For more than 20 years, alpha-1-proteinase inhibitor therapy has been the standard treatment for patients who have inherited alpha-1-proteinase inhibitor deficiency. Adult patients with this condition eventually develop emphysema. Most HIV-1 patients who have low viral load also have alpha-1-proteinase inhibitor deficiency. The number of CD4 cells in blood increases when alpha-1-proteinase inhibitor increases. Patients will be asked to participate in a pilot study to see whether the use of Zemaira® (alpha-1-proteinase inhibitor) can increase blood levels of alpha-1-proteinase inhibitor and consequently increase CD4 counts.
Study Details
Timeline
Interventions
Alpha-1-Proteinase Inhibitor was delivered I.V. A patient weighing 150 pounds was infused with approximately ½ cup containing 8.4 grams of alpha-1-Proteinase Inhibitor. Patients were admitted to hospital for infusion. The I.V. infusion was approximately 1 teaspoon/minute. Patients received weekly infusions of alpha-1-Proteinase Inhibitor for 8-12 weeks. At the time of infusion, 40ml (3 Tablespoons) of blood was collected (IRB approval #R04-003). The blood sample was used to monitor viral load, CD4 cell numbers, and alpha-1-Proteinase Inhibitor.
