The Safety and Utility of Skin Testing With XOLAIR® (Omalizumab) and Placebo Omalizumab (Formulation Excipients)
In Brief
A Phase 4 clinical trial evaluating Cohort I and Cohort 2 for Healthy and Asthma. Completed, enrolled 60 participants.
Detailed Summary
This study enrolled 30 healthy volunteers and 30 patients with atopic asthma, for a total of 60 subjects. The study examined the tolerability of omalizumab and omalizumab excipients in two successive cohorts of subjects, healthy volunteers and patients with allergic asthma without prior exposure to omalizumab, according to a skin test protocol, consisting of a prick skin test and/or intradermal test.

Interventions
In sterile water for injection (SWFI), full concentration and 1:1000, 1:100, 1:10 dilutions of 125 mg/mL of standard solution of omalizumab and its excipients. Skin prick test of each dilution concentration of 1:1000, 1:100, 1:10 and full concentration and Intradermal tests of each dilution concentration of 1:1000, 1:100 and 1:10 were followed by 20 minutes of observation. For the skin prick test, participants were tested initially with positive control (histamine 6 mg/mL) and negative control (saline), and with omalizumab and its excipients simultaneously from the lowest concentration. For the intradermal test, participants were tested initially with positive control (histamine 0.1 mg/mL) and negative control (saline), and with omalizumab and its excipients simultaneously from the lowest concentration. Dilutions of omalizumab and its excipients were in SWFI.
In a saline solution, full concentration and 1:1000, 1:100, 1:10 dilutions of 125 mg/mL of standard solution of omalizumab and its excipients. Skin prick test of each dilution concentration of 1:1000, 1:100, 1:10 and full concentration and Intradermal tests of each dilution concentration of 1:100,000 and 1:10,000 were followed by 20 minutes of observation. For the skin prick test, participants were tested initially by positive control (histamine 6 mg/mL) and negative control (saline), and with omalizumab and its excipients simultaneously from the lowest concentration. For the intradermal test, participants were tested initially with positive control (histamine 0.1 mg/mL) and negative control (saline), and with omalizumab and its excipients simultaneously from the lowest concentration. Dilutions of omalizumab and its excipients were made in saline.
