The safety profiles of the monthly 30- and 50-mg regimens and the daily 1-mg regimen were also compared. Materials and methods Patient enrollment We studied men and postmenopausal women with osteoporosis, aged 51 to 89 years, who had a BMD below 70% (T-score −2.6 at the LS) of the young adult mean (YAM) or a BMD below 80% (T-score −1.7 at the LS) of the YAM with at least one fragility fracture, as defined by the criteria of the Japanese Society for Bone and Mineral Research [9]. Vertebral fractures were assessed by X-ray www.selleckchem.com/JNK.html films of the vertebrae and were diagnosed in accordance with the criteria of

the Japanese Society for Bone and Mineral Research. Men with a total hip BMD below 70% (T-score −2.6 at the total hip) of the YAM were also eligible. Subjects were excluded if they had disorders such as primary hyperparathyroidism; Cushing’s syndrome; premature menopause due to hypothalamic, pituitary or gonadal insufficiency, or other causes of secondary osteoporosis; or if there were any radiographic findings that might affect bone densitometry assessment. Subjects with peptic ulcer were excluded. Subjects were excluded if they had received bisphosphonate injections, strontium, or RANKL antibody at any time. Subjects were also excluded if they had taken

oral bisphosphonates within the previous 1 year or for at least 30 days during the previous 2 years up until 1 year before the first dose of the study medication. Subjects were also excluded if they had taken glucocorticoids, calcitonin, vitamin K, active vitamin D compounds, MK-1775 solubility dmso or hormone replacement therapy within the previous 2 months; had serum calcium

(Ca) levels above 10.6 mg/dL (2.6 mmol/L) or below 8.0 mg/dL (2.0 mmol/L); had serum creatinine levels above 1.5 mg/dL (133 μmol/L); or had clinically significant hepatic disorders. This study was conducted in accordance with the principles that have their origin in the Declaration of Helsinki and was approved by the appropriate institutional review boards. All subjects gave written informed consent before undergoing any examination or study procedure, all of which were conducted Liothyronine Sodium in compliance with Good Clinical Practice. Eligibility of patients for enrollment was evaluated by H. Hagino—Rehabilitation Division, Tottori University Hospital, Yonago; M. Ito—Department of Radiology, Nagasaki University School of Medicine, Nagasaki; and T. Sone—Department of Nuclear Medicine, Kawasaki Medical School, Okayama. Study design This study was a randomized, double-blind, active-controlled, parallel-group, multicenter study conducted at 31 sites in Japan. Subjects who met all the entry criteria were enrolled and sequentially assigned an allocation number independent of study site. Subjects were randomized to take minodronate (Astellas Pharma Inc., Tokyo, Japan) at 1 mg daily, 30 mg monthly, or 50 mg monthly for 12 months.
