Outcomes
Primary Outcomes
Pharmacokinetics: Observed Maximum Serum Concentration (Cmax) Following Single Dose of Anifrolumab.
Time Frame: On Day 1 pre-dose and at 5 minutes (IV cohort only), 24 and 48 hours post-dose and at each follow-up visit, up to 85 days
To evaluate Cmax of anifrolumab after single administration of two doses subcutaneously and one dose intravenously. Up to 13 blood samples were collected in total.
Pharmacokinetics: Area Under the Serum Concentration-time Curve From Time Zero to Time of Last Quantifiable Concentration (AUC0-t) Following Single Dose of Anifrolumab
Time Frame: On Day 1 pre-dose and at 5 minutes (IV cohort only), 24 and 48 hours post-dose and at each follow-up visit, up to 85 days
To evaluate AUC(0-t) of anifrolumab after single administration of two doses subcutaneously and one dose intravenously Up to 13 blood samples were collected in total.
Pharmacokinetics: Area Under Serum Concentration-time Curve From Time Zero Extrapolated to Infinity (AUC) Following Single Dose of Anifrolumab
Time Frame: On Day 1 pre-dose and at 5 minutes (IV cohort only), 24 and 48 hours post-dose and at each follow-up visit, up to 85 days
To evaluate AUC of anifrolumab after single administration of two doses subcutaneously and one dose intravenously. Up to 13 blood samples were collected in total.
Safety: Number of Participants With Adverse Events (AEs)
Time Frame: From screening to final follow-up visit, up to 16 weeks
To assess the safety and tolerability of single doses of anifrolumab
Safety: Summary of Local Injection Site Pain (SC Cohorts) Assessed in Participants
Time Frame: Immediately after dosing, at 10, 20 minutes and 1 hour after injection
Local injection site pain was assessed using a 100 mm participant rated Visual Analog Scale (VAS 0mm - 100mm ungraduated scale, where 0 = "no pain" to 100 = "worst imaginable pain"). This assessment was taken for only those participants in subcutaneously dosed treatment groups; 600 mg SC and 300 mg SC, anifrolumab and placebo. For the 300 mg SC anifrolumab and 300 mg SC placebo groups which received two simultaneous injections, the average VAS score (0mm-100mm) of the two injection sites were reported.
Safety: Summary of Local Injection Site Pruritus (SC Cohorts) Assessed in Participants
Time Frame: Immediately after dosing, at 10, 20 minutes and 1 hour after injection
Local injection site pruritus was assessed using a 100 mm participant rated Visual Analog Scale (VAS 0mm - 100mm ungraduated scale, where 0 = "no itching" to 100 = "worst imaginable itching"). This assessment was taken for only those participants in subcutaneously dosed treatment groups; 600 mg SC and 300 mg SC, anifrolumab and placebo. For the 300 mg SC anifrolumab and 300 mg SC placebo groups which received two simultaneous injections, the average VAS score (0mm-100mm) of the two injection sites were reported.
Safety: Summary of Erythema Injection Site Reaction (SC Cohorts) Assessed in Participants
Time Frame: Immediately after dosing, at 10, 20 minutes and 1 hour after injection
Erythema was measured as the largest diameter across the needle site on the skin in millimetres (mm). This assessment was taken for only those participants in subcutaneously dosed treatment groups; 600 mg SC and 300 mg SC, anifrolumab and placebo. For the 300 mg SC anifrolumab and 300 mg SC placebo groups which received two simultaneous injections, the average of the two injection site diameters (mm) were reported.
Safety: Summary of the Induration Injection Site Reaction (SC Cohorts) Assessed in Participants
Time Frame: Immediately after dosing, at 10, 20 minutes and 1 hour after injection
Induration was measured as the largest diameter across the needle site on the skin in millimetres (mm). This assessment was taken for only those participants in subcutaneously dosed treatment groups; 600 mg SC and 300 mg SC, anifrolumab and placebo. For the 300 mg SC anifrolumab and 300 mg SC placebo groups which received two simultaneous injections, the average of the two injection site diameters (mm) were reported.
