In addition, any event that did not meet the regulatory definition of a serious adverse event, but in the opinion of the investigator or sponsor represented a significant medical hazard, was also considered a serious adverse event. Adverse events and LY333531 chemical structure serious adverse events of infections—those adverse events categorized in the MedDRA system organ class “Infections and Infestations”—were evaluated for this report. This category is broad and includes contagious as well as noncontagious (e.g., appendicitis, cholecystitis, diverticulitis) events. Information about antibiotic treatments was obtained from case narratives and/or RXDX-101 price concomitant medication listings. Microbial classification (bacterial, viral, or fungal)
could only be determined if cultures were collected at the time of event and culture results were reported by the investigators. Microbial classification was listed as unknown if cultures were not collected at the time of event, no organisms were isolated upon culture, or no culture results were reported. Serious adverse events of opportunistic infections were identified by a search of the clinical trial safety database using predefined
MedDRA terms that included fungal and mycobacterial infections. The presence of an organism by itself was not sufficient to qualify an adverse event as a serious opportunistic infection; events needed to meet the regulatory definition of serious (described above) and were verified by medical review. Colonization or localized infections were distinguished from invasive or disseminated infections. For example, shingles AZD5363 confined to a single dermatome would not be considered opportunistic, but herpes zoster infection that was disseminated or involved
multiple dermatomes would be included. Queries were generated by the sponsor to obtain additional information from investigators if important case-level detail was missing. Statistical analysis Demographic data for all randomized subjects were summarized Selleck Sirolimus by treatment group. Safety data were summarized by actual treatment received. Thus, seven subjects assigned to placebo who received a single dose of denosumab at some point during the study were included in the denosumab group for purposes of safety assessments. Yearly incidence rates of serious adverse events of infection were calculated. The temporal relationship between occurrence and resolution of serious adverse events of infections of interest and administration of investigational product was explored. P values were based on the log-rank test. The analyses did not include any adjustments for multiplicity and should be considered exploratory. Results Baseline characteristics of subjects enrolled in the pivotal phase 3 fracture trial have been previously reported . Subjects were primarily Caucasian (93%); the mean (SD) age was 72.3 (5.2) years and 74% were 70 years of age or older.
