RESUMEN
BACKGROUND AND AIMS: We aimed to assess the effects of cholesteryl ester transfer protein inhibitor anacetrapib added to statin ± other lipid-modifying therapies (LMT) in Japanese patients with dyslipidemia who were not at their LDL-C goal. METHODS: Patients on a stable dose of statin ± other LMT with LDL-C ≥100 mg/dL to <145 mg/dL, ≥120 mg/dL to <165 mg/dL, ≥140 mg/dL or ≥160 mg/dL for patients with a history of coronary heart disease (CHD), high-, moderate- and low-risk patients respectively, were randomized 2:1, stratified by background therapy, to double-blind anacetrapib 100 mg (n = 204) or placebo (n = 103) for 24 weeks, followed by a 28-week open-label extension phase (anacetrapib 100 mg) and a 12-week off-drug safety follow-up phase. The primary endpoint was percent change from baseline in LDL-C (beta-quantification method), as well as the safety profile of anacetrapib at Week 24; HDL-C was a key secondary endpoint. RESULTS: Anacetrapib 100 mg further reduced LDL-C (38.0%), non-HDL-C (35.1%), ApoB (28.7%), and Lp(a) (48.3%) and increased HDL-C (148.9%) and ApoAI (50.7%) versus placebo (p < 0.001 for all). There were no meaningful differences between the groups in the proportion of patients with liver enzymes elevations (2.0% vs. 0%), creatine kinase elevations overall (0.5% vs. 0%) or with muscle symptoms (0.5% vs. 0%), blood pressure, electrolytes or adjudicated cardiovascular events (0.5% vs. 0%). In the open-label period, sustained effects on lipid parameters were observed with anacetrapib and the treatment was generally well tolerated. CONCLUSIONS: Long-term treatment with anacetrapib 100 mg substantially reduced LDL-C, increased HDL-C and was well tolerated in Japanese patients with dyslipidemia (ClinicalTrials.gov number NCT01760460).

BACKGROUND AND AIMS: This multicenter, randomized, double-blind, placebo-controlled study assessed the lipid-modifying efficacy/safety profile of anacetrapib 100 mg added to ongoing statin ± other lipid-modifying therapies (LMT) in Japanese patients with heterozygous familial hypercholesterolemia (HeFH). METHODS: Patients 18-80 years with a genotype-confirmed/clinical diagnosis of HeFH who were on a stable dose of statin ± other LMT for ≥6 weeks and with an LDL-C concentration ≥100 mg/dL were randomized to anacetrapib 100 mg (n = 34) or placebo (n = 34) for 12 weeks, followed by a 12-week off-drug reversal phase. The primary endpoints were percent change from baseline in LDL-C (beta-quantification method [BQ]) and safety/tolerability. RESULTS: At Week 12, treatment with anacetrapib reduced LDL-C (BQ) compared to placebo and resulting in a between-group difference of 29.8% (95% CI: -38.6 to -21.0; p < 0.001) favoring anacetrapib. Anacetrapib also reduced non-HDL-C (23. 6%; p < 0.001), ApoB (14.1%; p < 0.001) and Lp(a) (48.7%; p < 0.001), and increased HDL-C (110.0%; p < 0.001) and ApoA1 (48.2%; p < 0.001) versus placebo. Anacetrapib 100 mg added to ongoing therapy with statin ± other LMT for 12 weeks was generally well-tolerated. There were no differences between the groups in the proportion of patients who discontinued drug due to an adverse event or abnormalities in liver enzymes, creatinine kinase, blood pressure, electrolytes or adjudicated cardiovascular events. CONCLUSIONS: In Japanese patients with HeFH, treatment with anacetrapib 100 mg for 12 weeks resulted in substantial reductions in LDL-C and increases in HDL-C and was well tolerated.

BACKGROUND: Recent evidence points to an increased incidence of new-onset diabetes and a negative impact on glucose parameters with statin use. This study examined the safety of ezetimibe vs placebo for change from baseline to week 24 in HbA1c (primary endpoint), glycoalbumin, and fasting plasma glucose (secondary endpoints) in Japanese subjects with type 2 diabetes and hypercholesterolemia. METHODS: This was a randomized, double-blind, placebo-controlled, parallel-group, multi-site trial. Adults with type 2 diabetes and hypercholesterolemia whose LDL-C measured <140 mg/dl (subjects receiving lipid-lowering drugs) or <160 mg/dl (subjects not receiving lipid-lowering drugs) at the start of the screening phase, were randomized after a 5-week wash-out period to ezetimibe 10 mg or placebo (1:1) for 24 weeks. Changes in HbA1c, glycoalbumin and fasting plasma glucose from baseline to week 24 were evaluated. The non-inferiority margin was set at 0.5% for HbA1c. RESULTS: Overall, 152 subjects were randomized (75 to ezetimibe and 77 to placebo). From baseline to 24 weeks, HbA1c significantly increased in both the ezetimibe and placebo groups (between-treatment difference 0.08 [95% CI: -0.07 to 0.23]). Ezetimibe was statistically non-inferior to placebo. At 24 weeks, the mean change from baseline in glycoalbumin levels (between-treatment differences 0.00 [95% CI: -0.47, 0.47]) and fasting plasma glucose (between-treatment differences -4.8 [95% CI: -12.1, 2.1]) were similar in both treatment groups. CONCLUSIONS: These results suggest that ezetimibe 10 mg does not result in dysregulation of glucose metabolism in Japanese patients with type 2 diabetes and hypercholesterolemia over 24 weeks of treatment.

Efficacy and tolerability of sitagliptin, a dipeptidyl peptidase-4 inhibitor, were assessed in Japanese patients with type 2 diabetes. In a multicenter, double-blind, randomized, placebo-controlled trial in Japan, 151 patients with inadequate glycemic control [HbA(1c) > or =6.5% to <10%, fasting plasma glucose (FPG) > or =126 to < or =240 mg/dL] were randomized to once-daily sitagliptin 100mg or placebo for 12 weeks. After 12 weeks, the least squares (LS) mean change from baseline HbA(1c) was -0.65% (95% CI: -0.80, -0.50) with sitagliptin versus 0.41% (0.26, 0.56) with placebo [between-group difference=-1.05% (-1.27, -0.84); p<0.001]. LS mean change from baseline FPG was -22.5mg/dL (95% CI: -28.0, -17.0) with sitagliptin versus 9.4 mg/dL (3.9, 14.9) with placebo [between-group difference=-31.9 mg/dL (95% CI: -39.7,-24.1); p<0.001]. More patients achieved HbA(1c) <7% or <6.5% with sitagliptin than with placebo (p<0.001). Following a meal tolerance test, 2-h postprandial glucose was significantly reduced with sitagliptin relative to placebo. Clinical and laboratory adverse experiences were similar between treatments, with no reported hypoglycemia adverse events with sitagliptin. Body weight was unchanged relative to baseline in the sitagliptin group (-0.1 kg), but significantly (p<0.01) different relative to the placebo group (-0.7 kg). In this study, once-daily sitagliptin 100mg for 12 weeks improved fasting and postprandial glycemic control and was generally well tolerated in Japanese patients with type 2 diabetes.

The efficacy and safety of treatment with oral alendronate (ALN) 35 mg once weekly for 52 weeks were compared with those of ALN 5 mg once daily in a double-blind, randomized, multicenter study of Japanese patients with involutional osteoporosis. The primary efficacy end point was the percent change from baseline in the lumbar spine (L1-L4) bone mineral density (BMD) after 52 weeks of treatment. In this study, 328 patients were randomized to ALN 5 mg once daily (160 patients) or ALN 35 mg once weekly (168 patients). The adjusted mean percent change from baseline in lumbar spine (L1-L4) BMD after 52 weeks of treatment was 5.8% and 6.4% in the once-daily group and the once-weekly group, respectively (both P < 0.001). The 95% confidence interval for the difference in spine BMD change between the two treatment groups was -0.31% to 1.48%, indicating that the two regimens were therapeutically equivalent, since the confidence interval fell entirely within the predefined equivalence criterion (+/-1.5%). The time course of the spine BMD increase was also similar for both regimens. Regarding total hip BMD, mean changes from baseline at 52 weeks were 2.8% and 3.0% in the once-daily group and the once-weekly group, respectively. In addition, the bone markers (urinary deoxypyridinoline, urinary type-I collagen N-telopeptides, and serum bone-specific alkaline phosphatase) were reduced to a similar level by either treatment throughout the treatment period. The tolerability and safety profiles were also similar between the treatment groups. Taken together, we conclude that the efficacy and safety of the ALN 35-mg once-weekly regimen are therapeutically equivalent to those of the ALN 5-mg once-daily regimen.
