A plain language summary on ritlecitinib treatment for adults and adolescents with alopecia areata.

WHAT IS THIS SUMMARY ABOUT?: This is a summary of the results of the ALLEGRO phase 2b/3 clinical trial, originally published in The Lancet. ALLEGRO-2b/3 looked at how well and safely the study medicine, ritlecitinib, works in treating people with alopecia areata ('AA' for short). The immune system protects your body from outside invaders such as bacteria and viruses. AA is an autoimmune disease, meaning a disease in which one's immune system attacks healthy cells of the body by mistake. In AA, the immune system attacks hair follicles, causing hair to fall out. AA causes hair loss ranging from small bald patches to complete hair loss on the scalp, face, and/or body. Ritlecitinib is a medicine taken as a pill every day, by mouth, that is approved for the treatment of severe AA. It blocks processes that are known to play a role in causing hair loss in patients with AA. WHAT WERE THE RESULTS OF THE STUDY?: Adults and adolescents (12 years and older) took part in the ALLEGRO-2b/3 study. They either took ritlecitinib for 48 weeks or took a placebo (a pill with no medicine) for 24 weeks. Participants taking placebo later switched to taking ritlecitinib for 24 weeks. The study showed that participants taking ritlecitinib had more hair regrowth on their scalp after 24 weeks than those taking the placebo. Hair regrowth was also seen on the eyebrows and eyelashes in participants taking ritlecitinib. Hair regrowth continued to improve to week 48 with continued ritlecitinib treatment. In addition, more participants taking ritlecitinib reported that their AA had 'moderately' or 'greatly' improved after 24 weeks than those taking the placebo. Similar numbers of participants taking ritlecitinib or placebo had side effects after 24 weeks. Most side effects were mild or moderate. WHAT DO THE RESULTS OF THE STUDY MEAN?: Ritlecitinib was an effective and well-tolerated treatment over 48 weeks for people with AA. Clinical Trial Registration: NCT03732807 (phase 2b/3 ALLEGRO study).

Efficacy and safety of ritlecitinib in adults and adolescents with alopecia areata: a randomised, double-blind, multicentre, phase 2b-3 trial.

BACKGROUND: Alopecia areata is characterised by non-scarring loss of scalp, face, or body hair. We investigated the efficacy and safety of ritlecitinib, an oral, selective dual JAK3/TEC family kinase inhibitor, in patients with alopecia areata. METHODS: In this randomised, double-blind, multicentre, phase 2b-3 trial done at 118 sites in 18 countries, patients aged 12 years and older with alopecia areata and at least 50% scalp hair loss were randomly assigned to oral ritlecitinib or placebo once-daily for 24 weeks, with or without a 4-week loading dose (50 mg, 30 mg, 10 mg, 200 mg loading dose followed by 50 mg, or 200 mg loading dose followed by 30 mg), followed by a 24-week extension period during which ritlecitinib groups continued their assigned doses and patients initially assigned to placebo switched to ritlecitinib 50 mg or 200 mg loading dose followed by 50 mg. Randomisation was done by use of an interactive response system and was stratified by baseline disease severity and age. The sponsor, patients, and investigators were masked to treatment, and all patients received the same number of tablets to maintain masking. The primary endpoint was Severity of Alopecia Tool (SALT) score 20 or less at week 24. The primary endpoint was assessed in all assigned patients, regardless of whether they received treatment. This study was registered with ClinicalTrials.gov, NCT03732807. FINDINGS: Between Dec 3, 2018, and June 24, 2021, 1097 patients were screened and 718 were randomly assigned to receive ritlecitinib 200 mg + 50 mg (n=132), 200 mg + 30 mg (n=130), 50 mg (n=130), 30 mg (n=132), 10 mg (n=63), placebo to 50 mg (n=66), or placebo to 200 mg + 50 mg (n=65). 446 (62%) of 718 patients were female and 272 (38%) were male. 488 (68%) were White, 186 (26%) were Asian, and 27 (4%) were Black or African American. Of 718 patients randomly assigned, 104 patients discontinued treatment (34 withdrew, 19 adverse events [AEs], 12 physician decision, 12 lack of efficacy, 13 lost to follow up, five rolled over to long-term study transfer, four pregnancies, two protocol deviations, one declined to attend follow-up due to COVID-19, one attended last visit very late due to COVID-19, and one non-compliance). At week 24, 38 (31%) of 124 patients in the ritlecitinib 200 mg + 50 mg group, 27 (22%) of 121 patients in the 200 mg + 30 mg group, 29 (23%) of 124 patients in the 50 mg group, 17 (14%) of 119 patients in the 30 mg group, and two (2%) of 130 patients in the placebo group had a response based on SALT score 20 or less. The difference in response rate based on SALT score 20 or less between the placebo and the ritlecitinib 200 mg + 50 mg group was 29·1% (95% CI 21·2-37·9; p<0·0001), 20·8% (13·7-29·2; p<0·0001) for the 200 mg + 30 mg group, 21·9% (14·7-30·2; p<0·0001) for the 50 mg group, and 12·8% (6·7-20·4; p=0·0002) for the 30 mg group. Up to week 48 and including the follow-up period, AEs had been reported in 108 (82%) of 131 patients in the ritlecitinib 200 mg + 50 mg group, 105 (81%) of 129 patients in the 200 mg + 30 mg group, 110 (85%) of 130 patients in the 50 mg group, 106 (80%) of 132 patients in the 30 mg group, 47 (76%) of 62 patients in the 10 mg group, 54 (83%) of 65 patients placebo to ritlecitinib 200 mg + 50 mg in the extension period, and 57 (86%) of 66 patients in the placebo to 50 mg group. The incidence of each AE was similar between groups, and there were no deaths. INTERPRETATION: Ritlecitinib was effective and well tolerated in patients aged 12 years and older with alopecia areata. Ritlecitinib might be a suitable treatment option for alopecia areata in patients who are candidates for systemic therapy. FUNDING: Pfizer.

Plain language summary: use of isavuconazole in Chinese patients with an invasive fungal disease.

WHAT IS THIS SUMMARY ABOUT?: Invasive aspergillosis (also known as IA) is a type of fungal infection, caused by a species of fungus called Aspergillus, that can be life threatening. Isavuconazole and voriconazole belong to a group of antifungal drugs called triazoles that are recommended for treating IA. In the USA and in Europe, isavuconazole is approved for treating patients with IA. In China, isavuconazole was recently being reviewed for approval for treating patients with IA. This study looked at whether isavuconazole works in the same way in healthy Chinese people as it does in healthy Western people. It also looked to see how well isavuconazole works and how many side effects it has compared with voriconazole in Chinese patients with IA. WHAT WERE THE RESULTS?: The results of this study showed that healthy Chinese people's bodies processed isavuconazole the same way as healthy Western people's bodies. The amount of drug in people's bodies did not change how well the drug worked or how many side effects there were. Isavuconazole worked as well as and had a similar number of side effects as voriconazole in treating Chinese patients with IA. WHAT DO THE RESULTS OF THE STUDY MEAN?: These findings show that isavuconazole may be a suitable treatment for Chinese patients with IA using the same dose that is used in Western patients.

TRS2P and LDL-C alone or in combination for predicting absolute benefits from additional LDL-C lowering: Analysis from the TNT trial.

BACKGROUND AND AIMS: Despite trial evidence, high intensity statins are underutilized in routine clinical practice. This study sought to assess the individual and joint contributions of the TRS2P score as a measure of residual risk and LDL-C levels to benefits from further LDL-C lowering in the TNT trial. METHODS: A total of 9980 patients were divided into 4 groups based on TRS2P and LDL-C at baseline: median (7.2%, group 4), NNT 78 vs. 14 (p-interaction <0.0001). CONCLUSIONS: Measures of residual risk as well LDL-C identify patients who remain at high risk despite statins with the combination identifying those who derive the greatest benefits from even modest additional LDL-C lowering. Attention to residual risk as well as LDL-C may further help to optimize guideline implementation.

Clinical experience with isavuconazole in healthy volunteers and patients with invasive aspergillosis in China, and the results from an exposure-response analysis.

BACKGROUND: Isavuconazole is a broad-spectrum triazole for the treatment of invasive fungal disease (IFD). OBJECTIVE: To investigate the clinical experience with isavuconazole in Chinese individuals. PATIENTS/METHODS: Participants were Chinese healthy volunteers from a Phase I pharmacokinetics (PK) and safety study of single/multiple doses of isavuconazole (n = 36) and Chinese patients from the global Phase III SECURE study that assessed safety and efficacy of isavuconazole vs voriconazole for IFD treatment (n = 26). RESULTS: No clinically relevant differences in PK were found between Chinese and Western participants, although exposure was increased in Chinese volunteers. Treatment-emergent adverse events (TEAEs) were reported in 75.0% of healthy volunteers, many of which were infusion-related. No serious AEs were reported. In SECURE, findings in Chinese patients (n = 26) were similar to the global population. For patients who received ≥1 dose of study drug, allcause mortality from first dose to Day 42 was 10.0% (1/10) with isavuconazole and 25.0% (4/16) with voriconazole (treatment difference [95% confidence interval, CI]: -15.0% [-43.2%, 13.2%]). Overall response at the end of treatment for patients with proven/probable IFD was 25.0% and 16.7% with isavuconazole and voriconazole, respectively (treatment difference [95% CI] -8.3% [-60.2%, 43.5%]). Isavuconazole was associated with lower incidence of hepatobiliary, eye, skin, subcutaneous tissue and psychiatric disorders compared with voriconazole and lower incidence of treatment-related TEAEs, serious TEAES or death overall. CONCLUSIONS: Although further research is required, this study demonstrated a favourable risk-benefit profile of isavuconazole in Chinese patients.

Strengthening the interpretability of clinical trial results by assessing the effect of informative censoring on the primary estimand in PRECISION.

BACKGROUND: The ICH E9(R1) addendum states that the strategy to account for intercurrent events should be included when defining an estimand, the treatment effect to be estimated based on the study objective. The estimator used to assess the treatment effect needs to be aligned with the estimand that accounted for intercurrent events. Regardless of the strategy, missing data resulting from patient premature withdrawal could undermine the robustness of the study results. Informative censoring due to dropouts in an events-based study is one such example. Sensitivity analyses using imputation methods are useful to examine the uncertainty due to informative censoring and address the robustness and strength of the study results. METHODS: We assessed the effect of premature patient withdrawal in the PRECISION study, a randomized non-inferiority clinical trial of patients with chronic arthritic pain that compared the cardiovascular safety of three nonsteroidal anti-inflammatory drugs-based treatment policies or paradigms. The protocol-defined use of concomitant or rescue medications was permitted since changes in pain medications due to insufficient analgesia were expected in patients in this long-term study. Anticipating that premature study discontinuations could potentially lead to informative censoring, a supplementary analysis was pre-specified in which censored outcomes due to the premature study discontinuation were imputed based on adverse events that were clinically associated with the primary endpoint (cardiovascular outcome based on the Antiplatelet Trialists Collaboration composite endpoint). Furthermore, tipping point analyses were conducted to test the robustness of the primary analysis results by assuming data censored not at random. The level of increase at which the primary study conclusion would change was estimated. RESULTS: For the analysis of time to first primary endpoint event through 30 months, 4065 out of the 24,081 enrolled patients were lost to follow-up, withdrew consent, or were no longer willing to participate in the study. These withdrawals occurred gradually and resulted in a cumulative total of 5893 censored patient-years of observation (10.2%). The rate of discontinuation and the baseline characteristics of the discontinued patients were similar across the three treatment groups. The non-inferiority conclusion from the primary analysis was confirmed in the supplementary analysis incorporating relevant adverse events. Furthermore, tipping point analyses demonstrated that in order to lose non-inferiority in the primary analysis, the risk of primary endpoint events during the censored observation time would have to increase by more than 2.7-fold in the celecoxib group while remaining constant in the other nonsteroidal anti-inflammatory drugs groups, demonstrating that the scenarios where the study results are invalid appear not plausible. CONCLUSIONS: Supplementary and sensitivity analyses presented to address informative censoring in PRECISION helped to further interpret and strengthen the study results.

Atorvastatin Reduces First and Subsequent Vascular Events Across Vascular Territories: The SPARCL Trial.

BACKGROUND: In the SPARCL (Stroke Prevention by Aggressive Reduction in Cholesterol Levels) trial, atorvastatin was compared with placebo in 4,731 participants with recent stroke or transient ischemic attack and no known coronary heart disease. Atorvastatin reduced the first occurrence of stroke and the first occurrence of a composite of vascular events. OBJECTIVES: The aim of this post hoc analysis was to assess the occurrence of all (first and subsequent) vascular events and the effect of atorvastatin to reduce these events by vascular territory (cerebrovascular, coronary, or peripheral) in SPARCL. METHODS: Treatment effects on total adjudicated vascular events, overall and by vascular territory, were summarized by marginal proportional hazards models. Vascular event rates were estimated for each treatment group with cumulative incidence functions. RESULTS: The placebo group had an estimated 41.2 first and 62.7 total vascular events per 100 participants over 6 years. There were 164 fewer first and 390 fewer total vascular events in the atorvastatin group (total events hazard ratio: 0.68; 95% confidence interval: 0.60 to 0.77). The total events reduction included 177 fewer cerebrovascular, 170 fewer coronary, and 43 fewer peripheral events. Over 6 years, an estimated 20 vascular events per 100 participants were avoided with atorvastatin treatment. CONCLUSIONS: In participants with recent stroke or transient ischemic attack, the total number of vascular events prevented with atorvastatin was more than twice the number of first events prevented. Total event reduction provides a comprehensive metric to capture the totality of atorvastatin clinical efficacy in reducing disease burden after stroke or transient ischemic attack.

Atorvastatin Has a Dose-Dependent Beneficial Effect on Kidney Function and Associated Cardiovascular Outcomes: Post Hoc Analysis of 6 Double-Blind Randomized Controlled Trials.

Background Kidney function decreases during the lifetime, and this decline is a powerful predictor of both kidney and cardiovascular outcomes. Statins lower cardiovascular risk, which may relate to beneficial effects on kidney function. We studied whether atorvastatin influences kidney function decline and assessed the association between individual kidney function slopes and cardiovascular outcome. Methods and Results Data were collected from 6 large atorvastatin cardiovascular outcome trials conducted in patients not selected for having kidney disease. Slopes of serum creatinine reciprocals representing measures of kidney function change ([mg/dL]-1/y), were analyzed in 30 621 patients. Based on treatment arms, patients were categorized into 3 groups: placebo (n=10 057), atorvastatin 10 mg daily (n=12 763), and 80 mg daily (n=7801). To assess slopes, mixed-model analyses were performed for each treatment separately, including time in years and adjustment for study. These slopes displayed linear improvement over time in all 3 groups. Slope estimates for patients randomized to placebo or atorvastatin 10 mg and 80 mg were 0.009 (0.0008), 0.011 (0.0006), and 0.014 (0.0006) (mg/dL)-1/y, respectively. A head-to-head comparison of atorvastatin 10 and 80 mg based on data from 1 study ( TNT [Treating to New Targets]; n=10 001) showed a statistically significant difference in slope between the 2 doses ( P=0.0009). From a Cox proportional hazards model using slope as a predictor, a significant ( P<0.0001) negative association between kidney function and cardiovascular outcomes was found. Conclusions In patients at risk of or with cardiovascular disease, atorvastatin improved kidney function over time in a dose-dependent manner. In the 3 treatment groups, kidney function improvement was strongly associated with lower cardiovascular risk. Clinical Trial Registration URL : http://www.clinicaltrials.gov .

High plasma FGF21 levels predicts major cardiovascular events in patients treated with atorvastatin (from the Treating to New Targets [TNT] Study).

BACKGROUND: Higher plasma fibroblast growth factor 21 (FGF21) levels predict incident cardiovascular events in type 2 diabetes patients. However, whether FGF21 levels predict cardiovascular events in statin-treated patients in the general population is unknown. We investigated whether FGF21 levels predict major cardiovascular event (MCVE) in the Treating to New Targets (TNT) trial participants. METHODS: After 8-week run-in on atorvastatin 10 mg/day, 10,001 patients with stable coronary disease in the TNT trial were randomized to 10 mg or 80 mg/day of atorvastatin for a median of 4.9 years. We analyzed data from 1996 patients with plasma FGF21 levels measured at randomization. Among them, 1835 patients had FGF21 measured one-year post-randomization. RESULTS: Higher ln-transformed FGF21 levels at randomization were associated with higher risk of incident MCVE (adjusted hazards ratio per SD increase = 1.18, P = 0.019). At 1-year post-randomization, FGF21 levels were lower in patients randomized to receive 80 mg versus 10 mg atorvastatin (186.9 versus 207.5 pg/mL respectively, P = 0.006). Higher ln-transformed FGF21 levels at 1-year post-randomization were also associated with higher subsequent risk of MCVEs (adjusted hazards ratio per SD increase = 1.24, P = 0.009). However, changes in FGF21 levels over 1-year were not related to subsequent MCVE risk. FGF21 levels had significant incremental value in net reclassification improvement in MCVE risk prediction. CONCLUSIONS: Higher plasma FGF21 levels are associated with higher CVD risk in statin-treated high-risk patients. Higher dose atorvastatin is associated with a reduction in FGF21 levels. FGF21 provides incremental value in CVD risk prediction in statin-treated patients.

Body Weight Variability and Cardiovascular Outcomes in Patients With Type 2 Diabetes Mellitus.

BACKGROUND: Some studies have shown that body weight variability is a risk factor for cardiovascular events, but this has not been studied in subjects with diabetes mellitus. METHODS AND RESULTS: We measured intraindividual variations in body weight from baseline and follow-up visits in 6408 subjects with type 2 diabetes mellitus from 3 clinical trials. The primary end point, any coronary event, was a composite of coronary heart disease death, myocardial infarction, resuscitated cardiac arrest, coronary revascularization, and unstable or new-onset angina. After adjustment for risk factors, baseline lipid levels, mean body weight, and weight change, each increase of 1 SD in body weight variability, measured as average successive variability and used as a time-dependent covariate, was associated with an increase in the risk of any coronary event (hazard ratio, 1.08; 95% CI, 1.01-1.14; P=0.017), major coronary event (hazard ratio, 1.12; 95% CI, 1.04-1.20; P=0.002), any cardiovascular event (hazard ratio, 1.08; 95% CI, 1.03-1.14; P=0.0015), and death (hazard ratio, 1.16; 95% CI, 1.10-1.22; P<0.0001). Among patients in the quintile with the highest variation in body weight compared with the lowest, the risk of any coronary event was 59% higher; the risk of a major coronary event, 82% higher; any cardiovascular event, 75% higher; death, 82% higher; myocardial infarction, 99% higher; and stroke, 92% higher in adjusted models. The results were consistent in a number of sensitivity analyses. CONCLUSIONS: Among subjects with type 2 diabetes mellitus, fluctuation in body weight was associated with higher mortality and a higher rate of cardiovascular events, independent of traditional cardiovascular risk factors.

Triglyceride-Rich Lipoprotein Cholesterol and Risk of Cardiovascular Events Among Patients Receiving Statin Therapy in the TNT Trial.

BACKGROUND: Mendelian randomization data suggest that the genetic determinants of lifetime higher triglyceride-rich lipoprotein-cholesterol (TRL-C) are causally related to cardiovascular disease and therefore a potential therapeutic target. The relevance of TRL-C among patients receiving statins is unknown. We assessed the relationship between TRL-C and cardiovascular risk, and whether this risk was modifiable among patients receiving statins in the TNT trial (Treating to New Targets). METHODS: Patients with coronary heart disease and low-density lipoprotein cholesterol (LDL-C) 130 to 250 mg/dL entered an 8-week run-in phase with atorvastatin 10 mg/d (ATV10). After this period, participants with LDL-C <130 mg/dL entered the randomized phase with ATV10 (n=5006) versus atorvastatin 80 mg/d (ATV80, n=4995). The primary end point was coronary heart disease death, nonfatal myocardial infarction, resuscitated cardiac arrest, or stroke (major adverse cardiovascular events [MACE]). TRL-C was calculated as total cholesterol minus high-density lipoprotein cholesterol minus LDL-C. The effect of atorvastatin on TRL-C was assessed during the run-in phase (ATV10) and randomized phase (ATV80 versus ATV10). The risk of MACE was assessed across quintiles (Q) of baseline TRL-C (and, for comparison, by baseline triglycerides and non-high-density lipoprotein cholesterol) during the randomized period. Last, the association between TRL-C changes with atorvastatin and cardiovascular risk was assessed by multivariate Cox regression. RESULTS: ATV10 reduced TRL-C 10.7% from an initial TRL-C of 33.9±16.6 mg/dL. ATV80 led to an additional 15.4% reduction. Cardiovascular risk factors positively correlated with TRL-C. Among patients receiving ATV10, higher TRL-C was associated with higher 5-year MACE rates (Q1=9.7%, Q5=13.8%; hazard ratio Q5-versus-Q1, 1.48; 95% confidence interval, 1.15-1.92; P-trend<0.0001). ATV80 (versus ATV10) did not significantly alter the risk of MACE in Q1-Q2, but significantly reduced risk in Q3-Q5 (relative risk reduction, 29%-41%; all P<0.0250), with evidence of effect modification ( P-homogeneity=0.0053); results were consistent for triglycerides ( P-homogeneity=0.0101) and directionally similar for non-high-density lipoprotein cholesterol ( P-homogeneity=0.1387). Last, in adjusted analyses, a 1 SD percentage reduction in TRL-C with atorvastatin resulted in a significant lower risk of MACE (hazard ratio, 0.93; 95% confidence interval, 0.86-1.00; P=0.0482) independent of the reduction in LDL-C and of similar magnitude to that per 1 SD lowering in LDL-C (hazard ratio, 0.89; 95% confidence interval, 0.83-0.95; P=0.0008). CONCLUSIONS: The present post hoc analysis from TNT shows that increased TRL-C levels are associated with an increased cardiovascular risk and provides evidence for the cardiovascular benefit of lipid lowering with statins among patients who have coronary heart disease with high TRL-C.

Visit-to-visit variability of lipid measurements as predictors of cardiovascular events.

BACKGROUND: Higher visit-to-visit variability in risk factors such as blood pressure and low-density lipoprotein (LDL)-cholesterol are associated with an increase in cardiovascular (CV) events. OBJECTIVE: The purpose of this study was to determine whether variability in high-density lipoprotein cholesterol (HDL-C) and triglyceride levels predicted coronary and CV events in a clinical trial population with known coronary disease. METHODS: We assessed intraindividual variability in fasting high-density lipoprotein (HDL)-cholesterol, triglyceride, and LDL-cholesterol measurements among 9572 patients in the Treating to New Targets trial and correlated the results with coronary events over a median follow-up of 4.9 years. RESULTS: In the fully adjusted Cox model, 1 standard deviation of average successive variability, defined as the average absolute difference between successive values, was associated with an increased risk of a coronary event for HDL-cholesterol (hazard ratio [HR] 1.16, 95% confidence interval [CI] 1.11-1.21, P < .0001), for triglycerides (HR 1.09, 95% CI 1.04-1.15, P = .0005), and for LDL-cholesterol (HR 1.14, 95% CI 1.09-1.19, P < .0001). Similar results were found for the 3 other measures of variability, standard deviation, coefficient of variability, and variability independent of the mean. Similar results were seen for CV events, stroke, and nonfatal myocardial infarction. Higher variability in triglyceride and LDL-cholesterol, but not HDL-cholesterol, was predictive of incident diabetes. The correlation among the variability of the 3 lipid measurements was weak. CONCLUSION: Visit-to-visit variability in fasting measurements of HDL-cholesterol, triglycerides, and LDL-cholesterol are predictive of coronary events, CV events, and for triglyceride and low-density lipoprotein cholesterol variability, incident diabetes. The mechanisms accounting for these associations remain to be determined.

Relationship of High-Density Lipoprotein Cholesterol With Renal Function in Patients Treated With Atorvastatin.

BACKGROUND: It is not known whether the concentration of high-density lipoprotein (HDL) cholesterol is related to renal function in statin-treated patients. We therefore investigated whether HDL cholesterol levels predicted renal function in atorvastatin-treated patients in the TNT (Treating to New Targets) trial. METHODS AND RESULTS: A total of 9542 participants were included in this analysis. Renal function was assessed by estimated glomerular filtration rate (eGFR). HDL cholesterol levels at month 3 were used as this is the time point at which on-treatment HDL cholesterol levels became stable. Among 6319 participants with a normal eGFR (≥60 mL/min per 1.73 m2) at baseline, higher HDL cholesterol levels at month 3 were significantly associated with lower risk of decline in eGFR (ie, having eGFR <60 mL/min per 1.73 m2) during follow-up (HR of 1.04, 0.88, 0.85, and 0.77 for HDL cholesterol quintiles 2, 3, 4, and 5, respectively, relative to quintile 1, P for trend=0.006). Among 3223 participants with an eGFR (<60 mL/min per 1.73 m2) at baseline, higher HDL cholesterol levels at month 3 had less impact on eGFR during follow-up, with statistical significance observed only when analyzing HDL cholesterol levels as a continuous variable (P=0.043), but not as a categorical quintile variable (P for trend=0.27). CONCLUSIONS: In patients treated with atorvastatin, higher HDL cholesterol levels were associated with lower risk of eGFR decline in patients with normal eGFR at baseline. However, further study is needed to establish whether there is any causal relationship between HDLs and renal function. CLINICAL TRIAL REGISTRATION: URL: https://www.clinicaltrials.gov.

Differential blood pressure effects of ibuprofen, naproxen, and celecoxib in patients with arthritis: the PRECISION-ABPM (Prospective Randomized Evaluation of Celecoxib Integrated Safety Versus Ibuprofen or Naproxen Ambulatory Blood Pressure Measurement) Trial.

AIMS: Non-steroidal anti-inflammatory drugs (NSAIDs), both non-selective and selective cyclooxygenase-2 (COX-2) inhibitors, are among the most widely prescribed drugs worldwide, but associate with increased blood pressure (BP) and adverse cardiovascular (CV) events. PRECISION-ABPM, a substudy of PRECISION was conducted at 60 sites, to determine BP effects of the selective COX-2 inhibitor celecoxib vs. the non-selective NSAIDs naproxen and ibuprofen. METHODS AND RESULTS: In this double-blind, randomized, multicentre non-inferiority CV-safety trial, 444 patients (mean age 62 ± 10 years, 54% female) with osteoarthritis (92%) or rheumatoid arthritis (8%) and evidence of or at increased risk for coronary artery disease received celecoxib (100-200 mg bid), ibuprofen (600-800 mg tid), or naproxen (375-500 mg bid) with matching placebos in a 1: 1: 1 allocation, to assess the effect on 24-h ambulatory BP after 4 months. The change in mean 24-h systolic BP (SBP) in celecoxib, ibuprofen and naproxen-treated patients was -0.3 mmHg [95% confidence interval (CI), -2.25, 1.74], 3.7 (95% CI, 1.72, 5.58) and 1.6 mmHg (95% CI, -0.40, 3.57), respectively. These changes resulted in a difference of - 3.9 mmHg (P = 0.0009) between celecoxib and ibuprofen, of - 1.8 mmHg (P = 0.12) between celecoxib and naproxen, and of - 2.1 mmHg (P = 0.08) between naproxen and ibuprofen. The percentage of patients with normal baseline BP who developed hypertension (mean 24-h SBP ≥ 130 and/or diastolic BP ≥ 80 mmHg) was 23.2% for ibuprofen, 19.0% for naproxen, and 10.3% for celecoxib (odds ratio 0.39, P = 0.004 and odds ratio 0.49, P = 0.03 vs. ibuprofen and naproxen, respectively). CONCLUSIONS: In PRECISION-ABPM, allocation to the non-selective NSAID ibuprofen, compared with the COX-2 selective inhibitor celecoxib was associated with a significant increase of SBP, and a higher incidence of new-onset hypertension.

Comparing the Safety and Efficacy of Celecoxib for the Treatment of Osteoarthritis in Asian and non-Asian Populations: An Analysis of Data from Two Randomized, Double-blind, Placebo-controlled, Active-comparator Trials.

INTRODUCTION: Celecoxib is an effective treatment for pain associated with osteoarthritis. There are differences in patient demographics among ethnic groups, with Asian populations typically smaller in body size. As a consequence, there may be a perception that celecoxib is less effective, or has poorer tolerability in Asian patients. METHODS: This analysis compares data from two multicenter, randomized, double-blind, placebo-controlled, active-comparator trials of celecoxib for the treatment of osteoarthritis of the knee: one study in Asian patients and the other in a mixed population comprised mostly of non-Asian patients (from which Asian patients were excluded for this analysis). Each trial was of similar design, with patients randomized 2:2:1 to 6 weeks treatment with celecoxib 200 mg once daily, active comparator (naproxen 500 mg twice daily or ibuprofen 800 mg three times daily), or placebo. The primary efficacy endpoint in each trial was the change from baseline to week 6 in the Patient's Assessment of Arthritis Pain, as measured on a visual analog scale. RESULTS: In total, 329 patients were included in the efficacy analysis, 179 in the Asian study and 150 in the non-Asian study. The Asian population was significantly older and smaller in body size (P < 0.0001). There was no significant difference between the Asian and non-Asian populations in change in pain score (95% confidence interval) at study endpoint with celecoxib [-1.1 (-7.7, 5.5); P = 0.7400] or placebo [-5.2 (-14.8, 4.4); P = 0.2870]. There were also no notable differences in safety outcomes between populations. CONCLUSIONS: Due to the smaller size of some Asian patients with OA, physicians may be tempted to decrease the dose of celecoxib below the therapeutic range recognized by regulatory authorities; these data suggest that dose changes are not necessary.

Effectiveness of Lipid-Lowering Statin Therapy in Patients With and Without Psoriasis.

BACKGROUND: Psoriasis is associated with dyslipidemia and metabolic syndrome, and has been linked to an increased cardiovascular risk. The aim of this study was to compare baseline characteristics and effects of statin therapy on lipid levels and cardiovascular outcomes in patients with and without psoriasis. METHODS: This post-hoc analysis assessed patients from one primary cardiovascular prevention statin trial (Collaborative AtoRvastatin Diabetes Study [CARDS]) and two secondary cardiovascular prevention statin trials (Treating to New Targets [TNT] and Incremental Decrease in End Points Through Aggressive Lipid Lowering [IDEAL]). Baseline characteristics, lipid changes from baseline, and cardiovascular event rates were analyzed. TNT and IDEAL data were pooled. RESULTS: Baseline characteristics and lipid profiles differed minimally in patients with and without psoriasis. In CARDS and TNT/IDEAL, similar apolipoprotein B, total cholesterol, and low-density lipoprotein cholesterol reductions occurred with statin therapy in patients with or without psoriasis. High-dose atorvastatin significantly reduced cardiovascular events vs. standard/low-dose statins in patients without psoriasis in TNT/IDEAL; similar numeric differences in event rates were observed in patients with psoriasis. CONCLUSIONS: In this post-hoc analysis, statins improved lipid levels and cardiovascular outcomes in patients with and without psoriasis, supporting statin use in patients with psoriasis.

Early, intensive statin treatment reduces 'hard' cardiovascular outcomes after acute coronary syndrome.

Background Early, intensive statin treatment is the standard of care after acute coronary syndrome (ACS). However, the benefit of this approach to prevent major adverse cardiovascular events has been demonstrated in only one randomised, placebo controlled trial. The Myocardial Ischemia Reduction with Aggressive Cholesterol Lowering (MIRACL) trial demonstrated that atorvastatin 80 mg daily, compared with placebo, reduced time to first occurrence of death, non-fatal myocardial infarction, resuscitated cardiac arrest, or hospitalisation for unstable angina (stroke not included) during the 16 week period following ACS. However, there were no significant effects on individual components of the composite endpoint except unstable angina. This led some to question whether early, intensive statin treatment reduces 'hard' events after ACS. Aim The burden of coronary heart disease after ACS, and therefore the efficacy of its treatment, depends not only on the occurrence of one ischaemic event, but rather on cumulative events experienced by patients. Accordingly, we conducted a post-hoc analysis of the MIRACL trial to examine the effect of atorvastatin on first as well as recurrent (i.e. total) hard cardiovascular events after ACS (death, myocardial infarction, stroke, and resuscitated cardiac arrest). Methods and Results In the 3086 patients who comprised the MIRACL trial, atorvastatin 80 mg did not reduce time to first hard event compared with placebo (hazard ratio 0.89, 95% confidence interval 0.72-1.10, P = 0.27). However, atorvastatin significantly reduced total hard events (hazard ratio 0.80, 95% confidence interval 0.66-0.97, P = 0.03). To prevent one hard event during the 16 weeks following ACS, only 11 patient-years of treatment with atorvastatin were required. Conclusion Early, intensive treatment with atorvastatin is an efficient intervention to reduce hard cardiovascular events after ACS.

Body-Weight Fluctuations and Outcomes in Coronary Disease.

BACKGROUND: Body-weight fluctuation is a risk factor for death and coronary events in patients without cardiovascular disease. It is not known whether variability in body weight affects outcomes in patients with coronary artery disease. METHODS: We determined intraindividual fluctuations in body weight from baseline weight and follow-up visits and performed a post hoc analysis of the Treating to New Targets trial, which involved assessment of the efficacy and safety of lowering low-density lipoprotein cholesterol levels with atorvastatin. The primary outcome was any coronary event (a composite of death from coronary heart disease, nonfatal myocardial infarction, resuscitated cardiac arrest, revascularization, or angina). Secondary outcomes were any cardiovascular event (a composite of any coronary event, a cerebrovascular event, peripheral vascular disease, or heart failure), death, myocardial infarction, or stroke. RESULTS: Among 9509 participants, after adjustment for risk factors, baseline lipid levels, mean body weight, and weight change, each increase of 1 SD in body-weight variability (measured according to average successive variability and used as a time-dependent covariate) was associated with an increase in the risk of any coronary event (2091 events; hazard ratio, 1.04; 95% confidence interval [CI], 1.01 to 1.07; P=0.01), any cardiovascular event (2727 events; hazard ratio, 1.04; 95% CI, 1.02 to 1.07; P<0.001), and death (487 events; hazard ratio,1.09; 95% CI, 1.07 to 1.12; P<0.001). Among patients in the quintile with the highest variation in body weight, the risk of a coronary event was 64% higher, the risk of a cardiovascular event 85% higher, death 124% higher, myocardial infarction 117% higher, and stroke 136% higher than it was among those in the quintile with the lowest variation in body weight in adjusted models. CONCLUSIONS: Among participants with coronary artery disease, fluctuation in body weight was associated with higher mortality and a higher rate of cardiovascular events independent of traditional cardiovascular risk factors.

Relation of Variability of Low-Density Lipoprotein Cholesterol and Blood Pressure to Events in Patients With Previous Myocardial Infarction from the IDEAL Trial.

In patients with previous myocardial infarction (MI), aggressive hypertension control and low-density lipoprotein cholesterol (LDL-C) reduction are important secondary prevention measures. However, residual risk remains despite aggressive treatment. Whether variability in blood pressure (BP) and LDL-C can explain this residual risk is not known. Patients enrolled in the Incremental Decrease in End Points Through Aggressive Lipid-Lowering trial with at least 1 post-baseline measurement of LDL-C and blood pressure (BP) were included. Visit-to-visit LDL-C and BP variabilities were evaluated using various measures of variability. Primary outcome was any coronary event with the secondary outcomes of any cardiovascular event (CV), MI, stroke, death, and CV death. Among the 8,658 patients included, each 1-SD (10.8 mg/dl) increase in LDL-C variability increased the risk of any coronary event (adjusted HR [HRadj] 1.07; 95% CI 1.04 to 1.11; p <0.0001), any CV event, MI, and death (HRadj 1.19; 95% CI 1.14 to 1.25; p <0.0001). Similarly, each 1-SD (7.2 mm Hg) increase in systolic BP variability increased the risk of any coronary event (HRadj 1.15; 95% CI 1.10 to 1.20; p <0.0001), any CV event, MI, stroke, death (HRadj 1.28; 95% CI 1.18 to 1.38; p <0.0001), and CV death. Compared with the group with low variability for both LDL-C and systolic BP, the group with high variability for both had a significant increase in any coronary event (HRadj 1.48; 95% CI 1.30 to 1.70), any CV event (HRadj 1.43; 95% CI 1.27 to 1.61), and MI (HRadj 1.87; 95% CI 1.46 to 2.41). In conclusions, in patients with a history of MI, variabilities in LDL-C and BP are powerful and independent predictors of CV events including death.

Safety of atorvastatin in Asian patients within clinical trials.

INTRODUCTION: Data on statin safety in Asian patients are limited compared with evidence from Western populations. AIM: This study assessed atorvastatin safety among Asian patients enrolled in 58 randomized clinical trials. METHODS: Data from 52 short-term trials (median exposure 4-72 weeks) and six long-term cardiovascular outcomes trials (median exposure 3.1-4.9 years) conducted across the atorvastatin 10-80-mg dose range were analyzed retrospectively to assess the incidence of safety endpoints. RESULTS: A total of 77 952 patients were identified (49 974 received atorvastatin), among whom 3191 were Asian (2519 received atorvastatin). In the short-term trials, the incidence of all-causality adverse events (AEs) and serious AEs (SAEs) in Asian patients treated with atorvastatin was similar to or lower than that observed with other statins or placebo, and discontinuations due to treatment-related AEs/SAEs were infrequent (2.0% across all doses). These observations were confirmed in the long-term trials. Treatment-related SAEs were rare (n = 4) among Asian patients receiving atorvastatin. No cases of rhabdomyolysis were observed in atorvastatin-treated Asian patients, and the incidence of myalgia was 1.8% in the short-term studies and 6.7% in the long-term trials. Elevations (>3× the upper limit of normal) in liver transaminases were observed in ~2% of Asian patients receiving atorvastatin; renal AEs occurred in <2%. CONCLUSION: The incidence of AEs/SAEs with atorvastatin 10-40-mg in patients of Asian origin was low and comparable to placebo. Further evaluation of atorvastatin 80-mg is required owing to the limited number of Asian patients (n = 281; 11.2%) who received this dose.
