Objectives: To investigate effects of romosozumab treatment on disease activity and bone mineral density (BMD) in patients with rheumatoid arthritis (RA) and severe osteoporosis in comparison with effects of denosumab treatment. Methods: A total of 50 women were enrolled in this study. The subjects were randomized equally into 2 groups: the romosozumab group or the denosumab group. Disease activity score in 28 joints (DAS28)- erythrocyte sedimentation rate (ESR) and BMD at lumbar spine were evaluated. Results: The percent changes (Δ) in the BMD values at 3 and 6 months for the lumbar spine were as follows: romosozumab; 4.9% and 5.2%, denosumab: 2.3% and 3.2%. The ΔBMD for the lumbar spine at 3 months was significantly higher in the romosozumab group than in the denosumab group (P= 0.044). The DAS28-ESR at baseline, 3 and 6 months in the romosozumab group were 2.88, 2.60 (P = 0.427) and 2.58 (P = 0.588), respectively. The change from baseline in DAS28-ESR did not differ significantly between these 2 groups at any time point. Conclusions: The present study revealed that romosozumab treatment is more effective than denosumab treatment in increasing BMD of the lumbar spine at 3 months. Furthermore, the present study suggested that romosozumab treatment has no effects on the disease activity of RA in patients with RA and severe osteoporosis for 6 months.

Objectives: This study aims to examine the 2-year outcomes of zoledronic acid (ZOL) with or without eldecalcitol (ELD) on bone mineral density (BMD) and fracture in Japanese patients with osteoporosis. Methods: The subjects were 98 patients who were randomly (1:1) assigned to treatment with ZOL combined with ELD (ZOL þ ELD group; n = 51) and ZOL alone (ZOL group; n = 47). Treatment efficacy was examined based on a comparison of changes in BMD from baseline (DBMD) in the lumbar spine, total hip, and femoral neck in the 2 groups. Results: The percent change from baseline in BMD values for the lumbar spine, total hip, and femoral neck at 24 months were 10.8% ± 6.1%, 6.0% ± 6.6%, and 5.1% ± 5.1%, respectively, in the ZOL þ ELD group, and 7.7% ± 6.2%, 5.1% ± 5.6%, and 2.9% ± 8.3%, respectively, in the ZOL group. The percent change from baseline BMD for the lumbar spine at 24 months differed significantly between the 2 groups. Conclusions: The effect of a combination of ZOL þ ELD on BMD for 24 months was more favorable than that of ZOL alone. This drug combination is promising for the treatment of drug-naïve Japanese patients with primary osteoporosis.

This study was conducted to evaluate the effectiveness of a combination of gemcitabine and nedaplatin therapy among patients with metastatic urothelial carcinoma previously treated with two lines of chemotherapy. Between February 2009 and August 2013, 30 patients were treated with gemcitabine and paclitaxel as a second-line chemotherapy. All had received a first-line chemotherapy consisting of methotrexate, vinblastine, doxorubicin and cisplatin. Ten patients who had measurable histologically proven advanced or metastatic urothelial carcinoma of the urinary bladder and upper urinary tract received gemcitabine $1,000mg/m^2$ on days 1, 8 and 15 and nedaplatin $70mg/m^2$ on day 2 as a third-line chemotherapy. Tumors were assessed by imaging every two cycles. The median number of treatment cycles was 3.5. One patient had partial response and three had stable disease. The disease-control rate was 40%, the median overall survival was 8.8 months and the median progression-free survival was 5.0 months. The median overall survival times for the first-line and second-line therapies were 29.1 and 13.9 months, respectively. Among disease-controlled patients (n=4), median overall survival was 14.2 months. Myelosuppression was the most common toxicity. There were no therapy-related deaths. Gemcitabine and nedaplatin chemotherapy is a favorable third-line chemotherapeutic option for patients with metastatic urothelial carcinoma. Given the safety and benefit profile seen in this study, further prospective trials are warranted given the implications of our results with regard to strategic chemotherapy for patients with advanced or metastatic urothelial carcinoma.
