If ibuprofen was contraindicated, acetaminophen was used in place of ibuprofen. Acetaminophen doses were adjusted so as it did not exceed 1000 mg per 6 hour or 4000 mg per day. A non-sedating antihistamine (cetirizine) was administered approximately 1 hour prior to each infusion of study drug. The recommended initial dose of cetirizine was 5 mg or 10 mg per day in adults and children aged 12 years and older. Normal saline solution was administered IV as needed to maintain hydration., Up to Day 8|Change From Baseline in Percent Glycosylated Hemoglobin (HbA1c), Participants were seen weekly during the first 4 weeks post-dose and then every other week through Week 12.
