The Safety and Utility of Skin Testing With XOLAIR® (Omalizumab) and Placebo Omalizumab (Formulation Excipients)

16 mai 2017 mis à jour par: Genentech, Inc.
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.

Armes et Interventions

Groupe de participants / Bras
Intervention / Traitement
Expérimental: Healthy Volunteers
Healthy participants were tested sequentially in a skin prick test procedure with positive control (histamine 6 mg/mL), negative control (saline), and 1:1000, 1:100, 1:10 dilution and full concentrations of both omalizumab and omalizumab excipients.
Médicament: Cohort I

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.
Expérimental: Allergic Asthma Participants
Allergic asthma participants were tested sequentially in a skin prick test procedure with positive control (histamine 6 mg/mL), negative control (saline), and a succession of 1:1000, 1:100, 1:10 dilutions and full concentration of both omalizumab and omalizumab excipients.
Médicament: Cohort 2

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.

Description de la mesure
Délai
Number of Participants by of Adverse Events Following a Skin Test Procedure
Délai: Up to 7 days following skin testing

Skin test procedures were skin prick test or intradermal test. The test started with the lowest concentration. If a positive skin reaction was observed, escalation to the next dilution was stopped. Subjects were observed for 20 minutes following each test; subjects were observed for 1 hour after the last intradermal test. Those with a positive response were observed for an additional 6 hours.

Severity refers to the intensity of an AE (mild, moderate or severe). Mild is itching or hives, for example. A severe event requires emergency medical treatment and can result in death.
Up to 7 days following skin testing
Number of Participants Who Experienced a Positive Skin Reaction (Skin Prick Test)
Délai: on the day of skin test
For skin prick, positive control (histamine 6 mg/mL) and negative control (saline) were used. Positive skin reaction was defined as a ≥ 3-mm wheal and/or > 10-mm erythema from negative control. The skin prick test started with the lowest concentration. If a positive skin reaction was observed, escalation to the next dilution was stopped.
on the day of skin test
Number of Participants Who Experienced a Positive Skin Reaction (Intradermal Test in Healthy Volunteers)
Délai: on the day of skin test
For intradermal testing, positive control (histamine 0.1 mg/mL) and negative control (saline) were used. Positive skin reaction was defined as a ≥ 3-mm wheal and/or > 10-mm erythema from negative control. The intradermal test started with the lowest concentration. If a positive skin reaction was observed, escalation to the next dilution was stopped.

Number of Participants Who Experienced a Positive Skin Reaction (Intradermal Test in Patients With Allergic Asthma)
Délai: on the day of skin test
For intradermal testing, positive control (histamine 0.1 mg/mL) and negative control (saline) were used. Positive skin reaction was defined as a ≥ 3-mm wheal and/or > 10-mm erythema from negative control. The intradermal test started with the lowest concentration.
