Project description:Patients with cerebrovascular disease (CeVD) have been shown to benefit from lipid-lowering therapies, but guideline-recommended levels of low-density lipoprotein cholesterol (LDL-C) are often not attained with statin treatment alone. The ORION-9, ORION-10, and ORION-11 trials evaluated the efficacy and safety of inclisiran in 3660 primary and secondary prevention patients with hyperlipidemia despite maximum tolerated statin treatment. This pooled post hoc analysis comprised 202 randomized patients from those trials with established CeVD who had received either 284 mg inclisiran (equivalent to 300 mg inclisiran sodium, n = 110) or placebo (n = 92) on Days 1, 90, and 6-monthly thereafter up to Day 540. At baseline, mean (SD) LDL-C was 108.4 (34.3) mg/dL and 110.5 (35.3) mg/dL in inclisiran and placebo arms, respectively. Inclisiran produced a mean (95% CI) placebo-corrected percentage change in LDL-C from baseline to Day 510 of -55.2 (-64.5 to -45.9; p < 0.0001); the corresponding time-adjusted percentage change from baseline after Day 90 and up to Day 540 was -55.2 (-62.4 to -47.9; p < 0.0001). Treatment-emergent adverse events (TEAEs) and TEAEs at the injection site, mostly mild, were more frequent with inclisiran versus placebo (82.7% vs 70.7% and 3.6% vs 0%, respectively). In patients with CeVD, twice-yearly dosing with inclisiran (after the initial and 3-month doses) in combination with maximally tolerated statins provided effective and consistent LDL-C reductions and was well tolerated.

Project description:BackgroundHomozygous familial hypercholesterolemia is a genetic disease characterized by extremely high levels of low-density lipoprotein cholesterol (LDL-C) and a high risk of premature cardiovascular events. The proof-of-concept study ORION-2 (A Study of Inclisiran in Participants With Homozygous Familial Hypercholesterolemia) showed that inclisiran, a small interfering RNA that prevents production of the hepatic PCSK9 protein (proprotein convertase subtilisin/kexin type 9), could lead to durable reductions in LDL-C levels when added to statins and ezetimibe in patients with homozygous familial hypercholesterolemia.MethodsORION-5 was a phase 3, 2-part, multicenter study in 56 patients with homozygous familial hypercholesterolemia and elevated LDL-C levels despite maximum tolerated doses of LDL-C-lowering therapies with or without lipoprotein apheresis. Patients eligible for part 1 (double-blind, 6 months) were randomized 2:1 to receive either 300 mg of inclisiran sodium (equivalent to 284 mg of inclisiran) or placebo. Placebo-treated patients from part 1 were transitioned to inclisiran in part 2 (open-label, 18 months). The primary end point was the percentage change in LDL-C levels from baseline to day 150.ResultsThe mean age of the patients was 42.7 years, and 60.7% were women. The mean baseline LDL-C levels were 294.0 mg/dL and 356.7 mg/dL in the inclisiran and placebo groups, respectively. The placebo-corrected percentage change in LDL-C level from baseline to day 150 was -1.68% (95% CI, -29.19% to 25.83%; P=0.90), and the difference was not statistically significant between the inclisiran and placebo groups. The placebo-corrected percentage change in PCSK9 levels from baseline to day 150 was -60.6% with inclisiran treatment (P<0.0001); this was sustained throughout the study, confirming the effect of inclisiran on its biological target of PCSK9. No statistically significant differences between the inclisiran and placebo groups were observed in the levels of other lipids and lipoproteins (apolipoprotein B, total cholesterol, and non-high-density lipoprotein cholesterol). Adverse events and serious adverse events did not differ between the inclisiran and placebo groups throughout the study.ConclusionsInclisiran treatment did not reduce LDL-C levels in patients with homozygous familial hypercholesterolemia despite substantial lowering of PCSK9 levels. Inclisiran was well-tolerated, and the safety findings were consistent with previously reported studies and the overall safety profile.RegistrationURL: https://www.clinicaltrials.gov; Unique identifier: NCT03851705.

Project description:AimsPatients often require combination therapies to achieve LDL cholesterol (LDL-C) targets for the primary prevention of atherosclerotic cardiovascular disease. This study investigates the effect of inclisiran, a small interfering ribonucleic acid targeting hepatic proprotein convertase subtilisin/kexin type 9 production, in primary prevention patients with elevated LDL-C despite statins.Methods and resultsThis pre-specified analysis of the placebo-controlled, randomized ORION-11 trial included 203 individuals at risk of, but without prior, cardiovascular events and LDL-C ≥2.6 mmol/L, despite maximally tolerated statins. Inclisiran 284 mg or placebo was administered on Days 1, 90, and thereafter every 6 months up to 540 days. Co-primary endpoints were percentage LDL-C change from baseline to Day 510 and time-adjusted change from baseline after Day 90 and up to Day 540. Key secondary endpoints included percentage and absolute changes in atherogenic lipoproteins. Safety was assessed over 540 days. The mean baseline (SD) LDL-C was 3.6 (1.5) mmol/L. At Day 510, the placebo-corrected LDL-C change with inclisiran was -43.7% [95% confidence interval (CI): -52.8 to -34.6] with a corresponding time-adjusted change of -41.0% (95% CI: -47.8 to -34.2); (P < 0.0001). The placebo-corrected absolute change in LDL-C at Day 510 with inclisiran was -1.5 mmol/L (95% CI: -1.8 to -1.2), with a respective time-adjusted change of -1.3 mmol/L (95% CI: -1.6 to -1.1). Inclisiran significantly lowered non-HDL cholesterol and apolipoprotein B (apoB) at Day 510 vs. placebo (P < 0.0001 for both), with a greater likelihood of attaining lipoprotein and apoB goals, and was well-tolerated except for mainly mild, treatment-emergent adverse events at the injection site.ConclusionInclisiran was generally well-tolerated in primary prevention patients with elevated LDL-C, who derived significant reductions in atherogenic lipoprotein levels with twice-yearly maintenance dosing.

Project description:AimsData describing the long-term efficacy and tolerability of inclisiran are limited. This was explored in ORION-8, an open-label extension of preceding Phase 2 and Phase 3 placebo-controlled and open-label extension trials.Methods and resultsFollowing completion of the parent trial, adult patients with atherosclerotic cardiovascular disease (ASCVD), ASCVD risk equivalent, or heterozygous familial hypercholesterolaemia received open-label inclisiran twice yearly (after initial and 3-month doses) until Day 990, followed by an end-of-study visit at Day 1080 or ≥ 90 days after the last dose. The study endpoints included the proportion of patients achieving pre-specified low-density lipoprotein cholesterol (LDL-C) goals [ASCVD: < 1.8 mmol/L (< 70 mg/dL); ASCVD risk equivalent: < 2.6 mmol/L (< 100 mg/dL)], percentage and absolute changes in LDL-C at end-of-study, and safety of inclisiran. Of 3274 patients, 2446 (74.7%) were followed until end-of-study. Mean age was 64.9 ± 9.9 years, 82.7% (n = 2709) had ASCVD, and mean baseline LDL-C was 2.9 ± 1.2 mmol/L. Mean cumulative exposure to inclisiran (including parent trials) was 3.7 years; maximum exposure was 6.8 years. With inclisiran, 78.4% [95% confidence interval (CI): 76.8, 80.0] of patients achieved pre-specified LDL-C goals and mean percentage change in LDL-C was -49.4% (95% CI: -50.4, -48.3). No attenuation of LDL-C lowering over time was observed. Treatment-emergent adverse events at injection site (all mild/moderate) occurred in 5.9% of the patients. Inclisiran-associated anti-drug antibodies were infrequent (5.5%) and had no impact on the efficacy or safety of inclisiran. No new safety signals were identified.ConclusionIn the largest and longest follow-up to date with >12 000 patient-years exposure, inclisiran demonstrated consistent and effective LDL-C lowering with a favourable long-term safety and tolerability profile.Trial registration numberClinicalTrials.gov identifier: NCT03814187.

Project description:IntroductionInclisiran, a small interfering RNA (siRNA), reduces the levels of low-density lipoproteins (LDL) in the body by preventing the hepatic synthesis of proprotein convertase subtilisin/kexin type 9 (PCSK9). However, there is limited pooled data regarding the efficacy and safety of inclisiran in patients with hypercholesterolemia.MethodsPubMed/MEDLINE, Embase and the Cochrane Library were searched by investigators from inception till July 2024 to identify randomised controlled trials (RCTs) that investigated inclisiran in patients with hypercholesterolemia. Weighted mean differences (MDs) for continuous outcomes and risk ratios (RRs) for the dichotomous outcomes were pooled. The analysis was conducted using the random effects model, and a p-value of < 0.05 was considered statistically significant.ResultsA total of 8 RCTs reporting data for 5016 patients were included in the pooled analysis. Our pooled analysis demonstrated that inclisiran was associated with a significant decline in the % of LDL-C levels (MD = -50.42, 95% CI: -56.15 to -44.70), % of PCSK9 levels (MD = -78.57, 95% CI: -81.64 to -75.50), % of total cholesterol levels in the body (MD = -31.22, 95% CI: -33.08.15 to -29.37), and apo B levels (MD = -41.47, 95% CI: -44.83 to -38.11) when compared with the control group. The risk of all-cause death, cardiovascular death, major adverse cardiovascular events, myocardial infarction, stroke, and serious adverse events remained comparable (p > 0.05) across the two groups.ConclusionInclisiran reduces LDL-C, PCSK9, cholesterol and apo-B levels in the body without increasing the risk of serious adverse events.

Project description:Purpose:Previous studies demonstrating efficacy and safety of once-daily umeclidinium (UMEC) in patients with chronic obstructive pulmonary disease (COPD) have included few Asian patients. This study evaluated efficacy and safety of UMEC 62.5 mcg versus placebo in Asian patients with COPD. Patients and Methods:A Phase III, randomized, double-blind, parallel-group study. Patients (aged ?40 years with COPD, pre-, and post-albuterol forced expiratory volume in 1 s [FEV1]/forced vital capacity ratio <0.70 and low risk of exacerbations) were randomized 2:1 to once-daily UMEC 62.5 mcg or placebo via the ELLIPTA inhaler for 24 weeks. Primary endpoint was change from baseline (CFB) in trough FEV1 on Day 169. Secondary endpoints were weighted mean FEV1 over 0-6 hrs post-dose on Day 1 and CFB in Transition Dyspnea Index (TDI) focal score on Day 168. Results:A total of 306 patients were included in the modified intent-to-treat population (UMEC: 205; placebo: 101). UMEC versus placebo provided a statistically significant improvement in least squares (LS) mean trough FEV1 between baseline and Day 169 (154 mL [95% confidence interval (CI): 113, 194]; p<0.001). A clinically meaningful difference of 125 mL in favor of UMEC (95% CI: 103, 147; p<0.001) was also seen in LS weighted mean FEV1 0-6 hrs post-dose on Day 1. A LS mean treatment difference in TDI focal score of 0.9 units in favor of UMEC was seen on Day 168 (95% CI: 0.3, 1.5; p=0.004). Incidence of on-treatment adverse events (AEs) was lower in the placebo (55%) versus UMEC arm (60%); non-fatal serious AEs, drug-related AEs, and AEs leading to withdrawal were similar with UMEC and placebo. Conclusion:Once-daily UMEC 62.5 mcg resulted in statistically significant and clinically meaningful improvements in lung function and dyspnea, compared with placebo, in Asian patients with COPD, with no new safety concerns observed.

Project description:BackgroundCombination of the inhaled long-acting muscarinic antagonist umeclidinium (UMEC; GSK573719) with the long-acting β2-agonist vilanterol (VI) is an approved maintenance treatment for COPD in the US and EU. We compared the efficacy and safety of UMEC/VI with placebo in patients with COPD of Asian ancestry.Patients and methodsIn this 24-week, Phase III, multicenter, randomized, double-blind, placebo-controlled, parallel-group study, patients were randomized 1:1:1 to UMEC/VI 125/25 μg, UMEC/VI 62.5/25 μg, or placebo. The primary efficacy end point was trough forced expiratory volume in 1 second (FEV1) on day 169; secondary end points were Transition Dyspnea Index (TDI) focal score at week 24 and weighted mean (WM) FEV1 over 0-6 hours postdose on day 1. Additional end points and safety were also assessed.ResultsBoth UMEC/VI 125/25 μg and UMEC/VI 62.5/25 μg statistically significantly improved trough FEV1 at day 169 versus placebo (UMEC/VI 125/25 μg, 0.216 L, [95% confidence interval [CI] 0.175-0.257]; UMEC/VI 62.5/25 μg, 0.151 L, 95% CI 0.110-0.191; both P<0.001). Statistically significant improvements in TDI score were observed for both UMEC/VI groups versus placebo (UMEC/VI 125/25 μg, 0.9, 95% CI 0.3-1.4, P=0.002; UMEC/VI 62.5/25 μg, 0.7, 95% CI 0.1-1.2, P=0.016). On day 1, both UMEC/VI groups improved 0-6-hour WM FEV1 versus placebo (UMEC/VI 125/25 μg, 0.182 L 95% CI 0.161-0.203; UMEC/VI 62.5/25 μg, 0.160 L, 95% CI 0.139-0.181; both P<0.001). Statistically significant improvements for UMEC/VI groups versus placebo were observed for rescue albuterol use at weeks 1-24 (puffs/day, both P<0.001). The incidence of adverse events was similar across groups.ConclusionIn Asian patients with COPD, once-daily UMEC/VI 125/25 μg and UMEC 62.5/25 μg resulted in clinically meaningful and statistically significant improvements in lung-function end points versus placebo. Symptomatic and quality of life measures also improved. The safety profile of UMEC/VI was consistent with previous studies.

Project description:We evaluated the efficacy and safety of as-needed tadalafil in a diverse clinical population (with varying patient demographics, disease severity, and comorbid medical conditions) of Asian men with erectile dysfunction (ED). An integrated analysis of five double-blind, placebo-controlled trials (N = 1 046) was performed. Patients were randomly assigned to receive 10 mg tadalafil (N = 185), 20 mg tadalafil (N = 510), or placebo (N = 351). Efficacy assessments included the International Index of Erectile Function (IIEF), Sexual Encounter Profile (SEP) diary and Global Assessment Question (GAQ). Patients receiving 10 mg or 20 mg tadalafil showed significant improvement from baseline-to-end point on the Erectile Function domain of the International Index of Erectile Function (IIEF-EF) domain score in all clinical sub-populations analyzed, compared with patients receiving placebo (P < 0.001). The 10-mg and 20-mg tadalafil groups showed a mean success rate of 64.1% and 70.5% for sexual intercourse attempts (SEP3, successful intercourse), respectively, compared with 33.4% in the placebo group (P < 0.001), and 85.5% and 85.4% reported improved erections at end point GAQ, respectively, versus 43.5% in the placebo group (P < 0.001). Tadalafil was well tolerated across all groups studied. Headache and back pain were the most frequently reported adverse events. Overall, tadalafil was effective and well tolerated across a diverse clinical spectrum of Asian men with ED.

Project description:Aims/introductionDiabetic peripheral neuropathic pain (DPNP) affects the functionality, mood and sleep patterns of patients with diabetes. Mirogabalin, an α2 δ ligand with a slower dissociation for α2 δ-1 versus α2 δ-2 subunits, showed efficacy and safety in a randomized, double-blind, placebo-controlled, 14-week study in Asian patients with DPNP. This open-label extension study evaluated the long-term safety and efficacy of mirogabalin in Asian patients with DPNP.Material and methodsThis 52-week open-label extension study was carried out in Japan, Korea and Taiwan in patients with DPNP. Patients received mirogabalin, initiated at 5 mg twice daily and increased to a flexible maintenance dosage of 10 or 15 mg twice daily. Adverse events were monitored throughout the study. Patients provided a self-assessment of pain using the Short-Form McGill Pain Questionnaire.ResultsOf the 214 patients who entered the study, 172 (80.4%) completed the extension study. Of 172 patients who completed the study, 149 received the highest dosage of mirogabalin (15 mg twice daily). The most common treatment-emergent adverse events were nasopharyngitis, diabetic retinopathy, peripheral edema, somnolence, diarrhea, increased weight and dizziness. Most treatment-emergent adverse events were mild or moderate in severity. The incidence of treatment-emergent adverse events leading to treatment discontinuation was 13.1%. The visual analog scale and all other Short-Form McGill Pain Questionnaire subscales (sensory score, affective score, total score and present pain intensity) generally decreased over time from baseline until week 52.ConclusionsThis extension study showed the safety and efficacy of a long-term flexible dosing regimen of mirogabalin 10 or 15 mg twice daily in patients with DPNP.

Project description:AimPost-hoc analysis of the efficacy and safety of ertugliflozin in East/Southeast (E/SE) Asian patients with type 2 diabetes mellitus (T2DM).Materials and methodsEfficacy evaluations used data from randomized, double-blind, phase 3 studies: a pool of two 26-week placebo-controlled studies and one 52-week active-comparator (glimepiride) study. Least squares mean change from baseline was calculated for HbA1c, fasting plasma glucose (FPG), body weight (BW) and systolic blood pressure (SBP). Safety evaluation included overall and prespecified adverse events based on pooled data (broad pool) from seven phase 3 studies (including studies in the efficacy analysis).ResultsAmong 161 E/SE Asian patients in the placebo pool (ertugliflozin, n = 106), ertugliflozin reduced HbA1c, FPG, BW and SBP from baseline at week 26. The placebo-adjusted changes from baseline for ertugliflozin 5 and 15 mg were: HbA1c, -0.9% and -1.0%; BW, -2.1 and -1.9 kg; and SBP, -3.3 and -3.5 mmHg, respectively. Among 174 E/SE Asian patients in the active-comparator study (ertugliflozin, n = 118), HbA1c changes from baseline at week 52 were -0.6%, -0.6% and -0.7% for ertugliflozin 5 mg, 15 mg and glimepiride, respectively. Ertugliflozin 5 and 15 mg reduced BW from baseline by -4.3 and -4.1 kg, respectively, and SBP by -7.4 and -9.3 mmHg, respectively, compared with glimepiride. Safety findings were generally consistent with overall ertugliflozin safety data published to date.ConclusionsTreatment with ertugliflozin was associated with reductions in HbA1c, FPG, BW and SBP, and was generally well tolerated in E/SE Asian patients with T2DM.
