Body temperature was measured orally at baseline. Patients completed a symptom questionnaire and recorded severity of baseline symptoms on a 100-mm visual analog scale (VAS; 0 [no symptoms] to 100 [severe symptoms]). The symptom questionnaire consisted of three questions (severity of fever, severity of headache, and severity of aches PU-H71 and pains), each rated on a four-point categorical

scale (0 [absent] to three [severe]). Study medication (acetaminophen, fluvastatin, or placebo) was administered 45 ± 15 min before ZOL administration. Rescue medication (unblinded ibuprofen) was dispensed, and patients were instructed to take ibuprofen in addition to study medication if they experienced severe discomfort. During the 3-day treatment period, patients completed the symptom questionnaire four times

daily (morning, midday, evening, and late evening) and then recorded their oral body temperature prior to taking study medication (acetaminophen/matching placebo). The VAS score was recorded once per day in the late evening. At the final visit, patient diaries were collected and patients returned used bottles and unused study and rescue medication. AEs and clinical chemistry variables were evaluated. Patients in the exploratory inflammatory biomarker subgroup had their first blood sample drawn on Day 1 prior to ingesting their blinded study medications. Additional blood samples were collected at 24 ± 2 and 72 ± 2 h after ZOL MM-102 in vitro infusion. FG-4592 mouse Blood samples were Miconazole processed by Quintiles Transnational (Durham, NC), and highly sensitive serum biomarker assays capable of measuring low normal levels were performed by Pacific Biomarkers of Seattle, WA (IL-6 and TNF-alpha: R&D Systems, Minneapolis, MN; interferon [IFN]-gamma: Meso Scale Discovery, Gaithersburg, MD; highly sensitive CRP [hs-CRP]: Roche Diagnostics

North America, Indianapolis, IN). The primary objective of this study was to demonstrate the superiority of acetaminophen vs. placebo in preventing clinically significant increases in body temperature or use of rescue medication during 3 days following ZOL infusion. Secondary objectives included assessment of whether fluvastatin was superior to placebo in preventing clinically significant increases in body temperature measured orally or use of rescue medication. Patients Postmenopausal women aged between 45 and 79 years with a clinical indication for bisphosphonate treatment for osteopenia or osteoporosis and a documented spine or hip bone mineral density dual-energy X-ray absorptiometry T-score of -1.5 or less were eligible for participation in this study. Women who had used IV bisphosphonates or taken oral bisphosphonates for more than 8 weeks or within 6 months of screening were excluded.
