043 and p = 0.012, respectively). QUALIOST® global scores were lower (indicating better QoL) in the strontium ranelate group than in the placebo group at each post-baseline assessment and significant between-group differences in favor of strontium ranelate in the change from baseline to endpoint (mean change from baseline in the strontium ranelate group = −0.06 and mean change from baseline in the placebo group = 1.92, p = 0.020) and from baseline to endpoint on treatment (mean change from baseline in the

strontium ranelate group = −0.40 and mean change from baseline in the placebo group = 1.63, p = 0.015) were observed. When the physical and emotional QUALIOST® dimensions were considered separately, a statistically significant between-group difference of the change from baseline to last value and from baseline to last value in treatment in favor of strontium ranelate was observed for both emotional score (p = 0.025 Vactosertib cell line and p = 0.012, respectively) and physical score (p = 0.022 and p = 0.034, respectively; Fig. 4).

or upper part of your back?’, QUALIOST® item 6) after 4 years of treatment was 28% higher in the strontium ranelate group than with placebo (p = 0.005). Indeed, 14.6% of patients receiving strontium ranelate versus 11.2% of patients receiving placebo were free of back pain [RR, 1.28; 95% CI (1.08, 1.52)]. Safety In all, over 4 years, 739 patients in the strontium ranelate group (89.5%) and 720 patients in the placebo group (88.5%) reported at least

one emergent adverse event under treatment. Diarrhea (6.3% versus 3.8%, respectively) and nausea (5.2% versus 3.8%, respectively) were more frequently DOK2 reported in the strontium ranelate group than in the placebo group. Skin disorders were reported similarly in both groups (14.5% in the strontium ranelate group and 15.1% in the placebo group), including dermatitis and eczema (2.1% versus 1.8% and 1.0% versus 1.2%, respectively). Over 4 years, four serious adverse events in each group concerning skin disorders were reported (one dermatitis and one contusion in each group, a pemphigoid and a lichen planus in the strontium ranelate group, and two skin ulcers in the placebo group). None were considered as related to the study drug by the investigators. Over 4 years, the number of patients reporting an embolism or a venous thrombosis was eight and five in the strontium ranelate and placebo groups, respectively. In the fifth year, in patients starting strontium ranelate (placebo/SR group), the number of emergent adverse events reported was similar to the SR/SR and SR/placebo groups (55.
