Abstract
As a selective estrogen receptor modulator (SERM), raloxifene is used in healthy postmenopausal women to prevent bone loss and reduce fractures. However, the benefit of raloxifene is uncertain in the treatment of osteoporosis among patients with end-stage renal disease (ESRD) or those who require maintenance dialysis. We assessed the safety and efficacy of raloxifene in this particular population. Studies were selected from PubMed, Springer, CNKI (Chinese National Knowledge Infrastructure) and Wanfang Database. Randomized controlled trials (RCTs) and prospective studies with control/placebo groups were included. Five studies were included with a total of 244 participants (121 patients in the raloxifene group and 123 patients in the placebo/control group). The median duration of treatment was 12 months. The incidence rate of side effects of raloxifene was 0/121 (0%). There was a significant improvement of lumbar spine bone mineral density (BMD) levels in the raloxifene group compared with the placebo group (MD: 33.88, 95% CI: 10.93, 56.84, p=0.004). There was no significant difference concerning the improvement of femoral neck BMD (MD: 8.42, 95% CI: -10.21, 27.04, p=0.38), intact parathyroid hormone (iPTH) (MD: -12.62, 95% CI: -35.36, 10.13, p=0.28), calcium (MD: -0.08, 95% CI: -0.61, 0.44, p=0.76), phosphorus (MD: 0.18, 95% CI: -0.12, 0.48, p=0.23) or bone alkaline phosphatase (BAP) (MD: -4.33, 95% CI: -14.44, 5.79, p=0.40). Raloxifene seems to be effective in improving the lumbar spine BMD in postmenopausal women with ESRD. More large RCTs are necessary to evaluate the long-term safety of raloxifene in uremic patients.

Journal of bone and mineral metabolism. 2017;(1):108-113
Abstract
Decline of body weight and body mass index (BMI) with aging is a major risk factor for osteoporosis and fracture, suggesting that treatment for osteoporosis may affect body composition. However, the effects of treatment for osteoporosis on body composition are not well known. The present study aimed to identify the relationship between raloxifene treatment and body composition markers. We measured bone mineral density (BMD), body composition, and bone remodeling markers in 236 Japanese postmenopausal women with raloxifene treatment (N = 50) and without treatment by any osteoporosis drug (N = 186) for 5 years and analyzed the relationship of these with BMD, BMI, body weight, and biochemical markers. The mean (SD) age of the participants was 65.5 (9.3) years. Percent-changes in body weight and BMI were significantly different between women taking raloxifene and those not taking any osteoporosis drugs (P = 0.03 and 0.048, respectively). Raloxifene treatment was a significant independent determinant of body weight and BMI. Long-term treatment with raloxifene prevents age-related weight loss.

Abstract
OBJECTIVE Removal of the ovaries is common during surgery for endometrial cancer. However, because loss of the ovaries can cause several health problems in patients, strategies for the prevention of such problems need to be established. Hence, we decided to conduct a multicenter randomized clinical trial to assess the effect of raloxifene on bone mineral density (BMD), bone metabolism, and the lipid profile of patients who had undergone surgery for patients with endometrial cancer. MATERIALS AND METHODS Patients with endometrial cancer were enrolled after treatment. The participants were randomized into 2 groups: group 1 included 39 women who received alfacalcidol (1 μg/d) alone and group 2 included 37 women who received alfacalcidol and the test drug, raloxifene hydrochloride, at a dose of 60 mg/d. The BMD of lumbar spine and femoral neck, serum bone markers, as well as lipid profile parameters were evaluated at enrollment as well as 6, 12, and 24 months after the enrollment. The primary efficacy end point was the percentage change from baseline to 24 months in lumbar spine (L2-L4) and femoral neck BMD. RESULTS Sixty-four women completed the 24-month study. At 24 months, the lumbar and femoral neck BMDs were significantly increased in group 2 compared with group 1 (3.5% vs -0.8% and 2.3% vs -2.8%, respectively). In group 2, low-density lipoprotein-cholesterol levels were significantly reduced by 13.6% and serum N-terminal telopeptide of type I collagen as well as bone-specific alkaline phosphatase values were significantly reduced by 16.7% and 25.7%, respectively. The patients who received adjuvant therapy for endometrial cancer showed a significantly higher response to raloxifene (5.8% vs 1.9%). Recurrence was detected in 2 (2.6%) patients in group 1. No severe adverse events were noted in any patient during the study period. CONCLUSIONS Raloxifene exerts positive effects on BMD, bone metabolism, and lipid profile parameters and could provide an improved therapeutic option for patients with endometrial cancer.

Abstract
OBJECTIVES To assess the effect of active vitamin D3 on quality of life (QOL) and pain in raloxifene-treated Japanese women with postmenopausal osteoporosis. RESEARCH DESIGN AND METHODS This is a post hoc analysis of a previous prospective postmarketing observational study conducted without a comparator group. This study was conducted in 60 Japanese hospitals from September 2007 to February 2009. We compared changes from baseline in QOL and pain in patients receiving raloxifene plus active vitamin D3 with those in patients receiving raloxifene monotherapy at 8 and 24 weeks after treatment. CLINICAL TRIAL REGISTRATION Japan Pharmaceutical Information Center (JapicCTI-070465). MAIN OUTCOME MEASURES QOL and pain were assessed using Short Form-8 (SF-8), European Quality of Life Instrument 5 Dimensions (EQ-5D), Japanese Osteoporosis Quality of Life Questionnaire (JOQOL), visual analogue pain scales (VAS pain), and pain frequency scores. RESULTS A total of 506 patients were included in the post hoc analysis. Both raloxifene monotherapy (RLX, n = 354) and active vitamin D3 cotreatment (COMBI, n = 152) significantly improved QOL and reduced pain from the baseline at Week 8 and Week 24. The COMBI group had significantly greater improvements in JOQOL total score and activity of daily living (total) domain at Week 24 and last observation carried forward (LOCF) than the RLX group. The COMBI group also had significantly greater improvements in SF-8 domains of general health (at Week 8, Week 24, and LOCF), role physical (at Week 24 and LOCF), and mental health (at LOCF) than the RLX group. The COMBI group also had significantly greater reduction in VAS pain at LOCF than the RLX group (mean [SD]: RLX = -0.99 [2.72], COMBI = -1.54 [2.21], P = 0.042). CONCLUSIONS Active vitamin D3 supplementation to raloxifene treatment for 24 weeks may have additional benefits in improving QOL and relieving pain in Japanese women with postmenopausal osteoporosis.

Abstract
Nine month teriparatide (TPTD) monotherapy followed by co-administration of raloxifene (RAL) or alendronate (ALN) for another nine 9 months resulted in incremental bone mineral density (BMD) increase. The aim of this study was to investigate the effects of continued antiresorptive treatments for 12 months in the extension phase. Postmenopausal women (n = 125) with severe osteoporosis on ongoing TPTD treatment for 9 months were randomized into three open-label groups for another 9 months: ALN (70 mg/week, n = 41), RAL (60 mg/d, n = 37) in addition to TPTD or no additional medication (n = 47) except Ca and vitamin D. After discontinuation of TPTD the respective antiresorptives were continued for a further 12 months, while patients in the TPTD monotherapy group received Ca and vitamin D. Amino-terminal propeptide of type I procollagen (P1NP) and cross-linked C-telopeptide (CTX), areal and volumetric BMD at the lumbar spine (LS) and hip were assessed. ALN resulted in continued BMD increase in LS (4.3 ± 1.5%; mean ± SD), femoral neck (4.2 ± 1.6%) and total hip (4 ± 1.6%; p < 0.001 for all), while RAL was only effective at the LS (2.4 ± 1.7%, p < 0.001) but no changes at the femoral neck (0.4 ± 1.4%) or total hip (-0.8 ± 1.5%) were observed. Cortical bone only increased in the ALN group (femoral neck 6.7 ± 2.7% and -1.3 ± 2.5%; total hip 13.8 ± 2.9% and -2.3 ± 2.5% for ALN and RAL, p < 0.001 for all; respectively). Analyzing the entire 30 months of therapy, the ALN group revealed the largest BMD increase in all regions. Our results suggest that the addition of ALN to ongoing TPTD and continuing ALN after TPTD was stopped may be beneficial for patients in terms of areal and volumetric BMD increase. Further research is warranted to determine the optimal timing of the initiation of the combination treatment, the respective antiresorptive medication and the potential benefit of this BMD increase regarding fracture prevention.

Abstract
BACKGROUND The Japanese Osteoporosis Quality of Life (JOQOL) questionnaire measures quality of life in Japanese patients with osteoporosis. However, several important aspects of the psychometric properties of individual domains, including responsiveness, have not been addressed to enable valid clinical application. This analysis examined the internal and external responsiveness of the JOQOL questionnaire. METHODS This was a post hoc analysis of a 24-week prospective postmarketing study of raloxifene (60 mg/day) administered to postmenopausal Japanese women with osteoporosis (JapicCTI-070465). Internal responsiveness was assessed using Standardized Response Mean (SRM) statistics and changes in JOQOL domain scores. Patients were also stratified into those who did or did not achieve a minimal clinically important change (MCIC) in pain, assessed by a visual analogue scale for pain (VAS pain): comparisons were made between treated patients who achieved VAS pain reduction ≥ 20 mm versus VAS pain reduction < 20 mm. External responsiveness was assessed using Pearson's correlation coefficient (r) for changes in JOQOL domain scores with Short Form-8 Health Survey and European Quality of Life Instrument scores. RESULTS Of 506 patients analyzed, 421 had a baseline value for VAS pain; of these, 152 patients (36.1%) had a MCIC, whereas 264 patients (62.7%) did not. The JOQOL domains pain, overall health, and falls/psychological factors had small to moderate SRM values (0.3-0.5) in all patients, but consistently showed significantly larger changes in patients whose pain score changes exceeded the MCIC. Together, these findings suggest some degree of internal responsiveness for these domains. However, activities of daily living domain had a SRM value as low as 0.2, and recreation/social activities and posture/physique domains had SRM values close to 0. Moderate correlation (defined as r ≥ 0.4 to < 0.6) was noted between the domains pain, activities of daily living, and overall health and some Short Form-8 Health Survey subscales and the European Quality of Life total score, suggesting external responsiveness of these domains. CONCLUSIONS The inconsistent responsiveness among individual JOQOL domains in treated patients suggests the need for improving several JOQOL domains, especially the activities of daily living, recreation/social activities and posture/physique domains, before application to clinical research.

Journal of endocrinological investigation. 2013;(11):1076-82
Abstract
AIM: To evaluate and compare the efficacy of alendronate sodium (ALN) and raloxifene (RLX) for the management of primary hyperparathyroidism (PHPT) in postmenopausal female patients (pts) with osteoporosis. METHODS Twenty-four postmenopausal women with osteoporosis who were diagnosed with PHPT, but refused the option of surgery, were enrolled. Participants were sequentially randomized into two groups: an ALN-group of 12 pts (70 mg/week) and a RLX-group of 12 pts (60 mg/day). The control group consisted of 10 pts with PHPT who did not have any indications for surgery. RESULTS The decrease in ionized calcium levels was significantly more pronounced in the ALN group compared to the RLX and control groups (p<0.001). In terms of difference from baseline in bone mineral density (BMD) of the lumbar area in percentages over a period of 12 months, pts in the ALN and RLX groups both showed statistically significant improvements compared to pts in the control group (control vs ALN, p<0.001; control vs RLX, p<0.001). BMD measurements of the femoral and radial areas were comparable in all three groups. CONCLUSIONS ALN and RLX may improve bone density in the lumbar area of osteoporotic post-menopausal women with PHPT. The more significant decrease in serum calcium levels which was observed in the ALN group compared to both RLX and control groups, suggests that ALN could be used for the short-term control of calcium levels in patients awaiting surgery.

Mori, H, Okada, Y, Kishikawa, H, Inokuchi, N, Sugimoto, H, Tanaka, Y
Journal of bone and mineral metabolism. 2013;(1):89-95
Abstract
Evidence suggests that bone quality is poorer and fracture risk is higher in patients with diabetes, even those with normal bone mineral density. The aim of this study was to determine the effects of raloxifene on lipid, bone, and glucose metabolism in postmenopausal women with type 2 diabetes. The study subjects (144 postmenopausal women aged less than 80 years with type 2 diabetes) were randomly assigned into three groups: no medication, alfacalcidol 1 μg/day, or raloxifene hydrochloride 60 mg/day. The primary endpoint was the change in LDL-C at 6 months. Raloxifene significantly decreased the levels of bone metabolism markers NTX and BAP at 6 months in patients with diabetes. The primary endpoint, LDL-C at 6 months, was significantly lower in the raloxifene group than in the other two groups. However, percent changes in HDL-C were not significantly different among the three groups. Although glucose metabolism was unaffected, homocysteine, a bone quality marker, was significantly decreased at 6 months in the raloxifene group. The percent improvement in LDL-C did not correlate with percent improvement in any bone metabolism or bone quality markers. Raloxifene, unlike estrogen, improved LDL-C and decreased homocysteine, indicating that raloxifene can potentially improve LDL-C as well as bone quality in postmenopausal women with type 2 diabetes.

Abstract
INTRODUCTION We previously demonstrated that 1 or 5 mg per day of tamoxifen (T) given for four weeks before surgery reduces Ki-67 in breast cancer (BC) patients to the same extent as the standard 20 mg/d. Given the long half-life of T, a weekly dose (10 mg per week (w)) may be worth testing. Also, raloxifene (R) has shown Ki-67 reduction in postmenopausal patients in a preoperative setting, but data in premenopausal women are limited. We conducted a randomized trial testing T 10 mg/w vs. R 60 mg/d vs. placebo in a presurgical model. METHODS Out of 204 screened subjects, 57 were not eligible, 22 refused to participate and 125 were included in the study. The participants were all premenopausal women with estrogen receptor-positive BC. They were randomly assigned to either T 10mg/w or R 60 mg/d or placebo for six weeks before surgery. The primary endpoint was tissue change of Ki-67. Secondary endpoints were modulation of estrogen and progesterone receptors and several other circulating biomarkers. RESULTS Ki-67 was not significantly modulated by either treatment. In contrast, both selective estrogen receptor modulators (SERMs) significantly modulated circulating IGF-I/IGFBP-3 ratio, cholesterol, fibrinogen and antithrombin III. Estradiol was increased with both SERMs. Within the tamoxifen arm, CYP2D6 polymorphism analysis showed a higher concentration of N-desTamoxifen, one of the tamoxifen metabolites, in subjects with reduced CYP2D6 activity. Moreover, a reduction of Ki-67 and a marked increase of sex hormone-binding globulin (SHBG) were observed in the active phenotype. CONCLUSIONS A weekly dose of tamoxifen and a standard dose of raloxifene did not inhibit tumor cell proliferation, measured as Ki-67 expression, in premenopausal BC patients. However, in the tamoxifen arm women with an extensive phenotype for CYP2D6 reached a significant Ki-67 modulation.

Abstract
BACKGROUND/OBJECTIVES The antiestrogen, Raloxifene (Ral) is an effective breast cancer chemopreventive agent. Omega-3 fatty acids (n-3FA) may inhibit mammary carcinogenesis. On the basis of their mechanisms of action, we test the hypothesis that a combination of n-3FA and Ral may be superior in reducing select biomarkers of breast cancer risk in women. SUBJECTS/METHODS Postmenopausal women at increased risk for breast cancer (breast density ≥ 25%) were randomized to: (1) no intervention; (2) Ral 60 mg; (3) Ral 30 mg; (4) n-3FA (Lovaza) 4 g and (5) Lovaza 4 g+Ral 30 mg for 2 years. Reduction in breast density is the primary end point of the study. We report preliminary data on feasibility, compliance and changes in secondary end points related to IGF-I signaling, estrogen metabolism, oxidative stress and inflammation in the first group of 46 women who completed 1 year of the study. RESULTS All interventions were well tolerated with excellent compliance (96 ± 1% overall) by pill count and also supported by the expected rise in both serum n-3FA and n-3FA/Omega-6 fatty acids (n-6FA) ratio in women randomized to groups 4 and 5 (P<0.05). Lovaza decreased serum triglycerides and increased high-density lipoprotein (HDL) cholesterol compared with control (P<0.05 for both). Ral reduced serum IGF-1 in a dose-dependent manner (P<0.05) while Lovaza did not. Lovaza had no effect on IGF-1 or IGFBP-3. None of the other biomarkers were affected by our treatment. CONCLUSION The combination of Lovaza and Ral is a feasible strategy that may be recommended in future breast cancer chemoprevention trials.
