Proposed low-density lipoprotein cholesterol goals for secondary prevention and familial hypercholesterolemia in India with focus on PCSK9 inhibitor monoclonal antibodies: Expert consensus statement from Lipid Association of India.

Rates of atherosclerotic cardiovascular disease (ASCVD) are strikingly high in India compared to Western countries and are increasing. Moreover, ASCVD events occur at a younger age with only modest hypercholesterolemia, most commonly with low levels of high-density lipoprotein cholesterol. The course of ASCVD also appears to be more fulminant with higher mortality. In light of these issues, the Lipid Association of India (LAI) endeavored to develop revised guidelines with more aggressive low-density lipoprotein cholesterol (LDL-C) goals in secondary prevention and for patients with familial hypercholesterolemia compared to guidelines in the United States and other countries. Owing to the paucity of clinical outcomes data in India, it was necessary to place major emphasis on expert opinion as a complement to randomized placebo-controlled data generated mostly in non-Indian cohorts. To facilitate this process, the LAI conducted a series of 19 meetings among 162 lipid specialists in 13 cities throughout India over a period of 11 months before formulating this expert consensus statement. The LAI recommends an LDL-C goal <50 mg/dL in all patients in secondary prevention or very high-risk primary prevention but proposes an optional goal ≤30 mg/dL in category A extreme-risk patients (eg, coronary artery disease + familial hypercholesterolemia) and a recommended goal ≤30 mg/dL in category B extreme-risk patients [coronary artery disease + (1) diabetes and polyvascular disease/≥3 major ASCVD risk factors/end organ damage, or (2) recurrent acute coronary syndrome within 12 months despite LDL-C <50 mg/dL, or (3) homozygous familial hypercholesterolemia]. More aggressive LDL-C goals are needed for prevention of ASCVD in India, as described in this expert consensus statement. Use of statins and ezetimibe needs to increase in India in combination with improved control of other ASCVD risk factors. Proprotein convertase subtilisin kexin type 9 inhibitors can improve LDL-C goal achievement in patients with refractory hypercholesterolemia.

Clinical reality and challenges with familial hypercholesterolemia patients' management. 2024 results from the Regional Center for Rare Diseases (RCRD) Registry in Poland.

Despite advancements in early diagnosis and effective medications in last decade, most heterozygous familial hypercholesterolemia (heFH) patients still fail to achieve their low-density lipoprotein cholesterol (LDL-C) goals and remain at residual cardiovascular disease risk. We present recent data from the regional FH registry in Poland, highlighting the challenges and real-life clinical management of FH patients. The registry is held at the Regional Centre for Rare Diseases, founded in 2016, at the 2nd largest, supraregional hospital in Poland, where >80 different rare diseases in patients from all over Poland are diagnosed and treated, including phenotypically or genetically diagnosed FH patients. Our analysis focused on both children and adult FH patients, excluding those treated with inclisiran due to a small sample size (n = 5). We studied 173 consecutive heFH patients, median age for adult population was 40 years (range: 27-57), of whom 56.14 % were women. Among the population, 82.1 % were adults (n = 142), and 31 were children (17.92 %; median age 9 (8-13), females 58.16 %). Children exhibited lower total cholesterol and triglyceride levels compared to adults, with no significant differences in LDL-C and high-density lipoprotein cholesterol (HDL-C) levels. Molecular diagnosis in the whole population revealed that 76.6 % had an LDL receptor (LDLR) mutation, while 23.4 % had an apolipoprotein B (APOB) mutation. Risk assessment categorized patients into high (70.7 %), very high (22.1 %), and extremely high (7.1 %) risk groups. Triple therapy achieved treatment goals in 61.76 % of adults and 70.97 % of children. At baseline, 36.62 % of adult patients were not using statins. High-intensity statin therapy combined with ezetimibe was initiated for the remaining patients. Only 3.33 % of patients avoided statins due to complete intolerance. Ezetimibe was used in 57.27 % of patients (mostly in combination therapy), and proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors were prescribed for 28.17 % FH patients. In adults receiving statin and ezetimibe therapy, median achieved LDL-C was 141 mg/dl (107-184). For triple therapy, median achieved LDL-C was 52.5 mg/dL (32-86.5). Overall median achieved LDL-C in the study population was 99.5 mg/dl (57.5-145.4). PCSK9 inhibitors reduced LDL-C by 165.6 mg/dl. Combination therapy did not significantly alter baseline lipoprotein(a) (Lp(a)) levels (p = 0.134), and PCSK9 inhibitors led to a mean Lp(a) reduction of 18.66 mg/dl (45 % reduction; p = 0.013). Multivariable regression analysis identified key factors for achieving LDL-C targets in FH patients: DLCN total score, DLCN category, ezetimibe use, and PCSK9 inhibitors. In Poland, FH patients are often diagnosed too late (usually over 40 years of age), and many still do not reach their LDL-C goals. Combination LLT double or triple therapy significantly increases the likelihood of achieving LDL-C targets - even up to fivefold. Therefore, unrestricted access to PCSK9 inhibitors for all FH patients is crucial, without the current limitations imposed by drug reimbursement programs like B101.

Recaticimab as Add-On Therapy to Statins for Nonfamilial Hypercholesterolemia: The Randomized, Phase 3 REMAIN-2 Trial.

Currently available antiproprotein convertase subtilisin/kexin type 9 monoclonal antibodies can effectively decrease low-density lipoprotein cholesterol (LDL-C) levels, but require frequent dosing. Recaticimab is a novel humanized monoclonal antibody against proprotein convertase subtilisin/kexin type 9. In a phase 1b/2 trial, recaticimab as add-on to stable statins showed robust LDL-C reduction with a dosing interval up to every 12 weeks (Q12W) in patients with hypercholesterolemia. REMAIN-2 (REcaticiMab Add-on therapy In patients with Nonfamilial hypercholesterolemia) aimed to assess the efficacy and safety of 48-week treatment with recaticimab as add-on therapy to statins in nonfamilial hypercholesterolemia. REMAIN-2 was a multicenter, randomized, double-blind, placebo-controlled, phase 3 trial. During the run-in period, patients received stable moderate or high-intensity statin, with or without cholesterol absorption inhibitors (ezetimibe) or fenofibrate, for ≥4 weeks. Patients with an LDL-C of ≥1.8 mmol/L (if with atherosclerotic cardiovascular disease [ASCVD]) or ≥2.6 mmol/L (if without ASCVD) were then randomized (2:2:2:1:1:1) to receive recaticimab 150 mg every 4 weeks (Q4W), 300 mg every 8 weeks (Q8W), or 450 mg Q12W, or matching placebo injections (Q4W, Q8W, or Q12W) for 48 weeks. The primary efficacy endpoint was percentage change from baseline to week 24 in LDL-C level. A total of 689 randomly assigned patients received treatment (mean age, 55.8 years; male, 64.4%; ASCVD history, 69.5%; concomitant ezetimibe, 11.2%; mean baseline LDL-C, 2.8 mmol/L). Percentage change in LDL-C from baseline to week 24 was significantly more pronounced with recaticimab vs placebo (P < 0.0001), with least-squares mean differences of -62.2% (95% CI: -67.0% to -57.4%), -59.7% (95% CI: -65.0% to -54.4%), and -53.4% (95% CI: -58.7% to -48.2%) for the 150 mg Q4W, 300 mg Q8W, and 450 mg Q12W regimens, respectively. The decreases in LDL-C with recaticimab were maintained through week 48. Secondary lipid variables, including non-high-density lipoprotein cholesterol, apolipoprotein B, and lipoprotein(a) also favored the recaticimab groups. During the treatment period, the incidence of treatment-related adverse events (28.5% vs 26.6%) and serious treatment-related adverse events (0.4% vs 0.4%) was similarly low in both the recaticimab and placebo groups. Recaticimab as add-on to stable statin therapy significantly decreased LDL-C levels at week 24 and sustained the decreases through week 48, providing a novel therapeutic alternative with a dosing interval of up to every 12 weeks in patients with nonfamilial hypercholesterolemia.

The German Lipoprotein Apheresis Registry-Summary of the eleventh annual report.

In 2012, the German Lipoprotein Apheresis Registry (GLAR) was launched. Real-world data on lipoprotein apheresis (LA) treatment are now available for a time period of 11 years. All patients received the maximally tolerated lipid-lowering therapy, which included statins, ezetimibe, bempedoic acid, and either proprotein convertase subtilisin/kexin type 9 (PCSK9) antibodies or antisense therapy. During the time period from 2012 to 2022, 92 German apheresis centers collected retrospective and prospective observational data of a total of 2,301 patients undergoing regular lipoprotein apheresis (LA) treatment of hypercholesterolemia or/and Lp(a)-hyperlipoproteinemia suffering from progressive atherosclerotic cardiovascular disease (ASCVD), with complete data sets of 1.125 patients, who were the subject of this analysis. More than 61,500 LA sessions are documented in the database. In 2022, all patients treated with LA demonstrated a significant immediate median reduction rate of LDL-C (68.8 %) and Lp(a) (72.9 %). Patient data were analyzed for the incidence rate of major coronary events (MACE) 1 and 2 years before the beginning of LA treatment (y-2 and y-1) and prospectively up to eleven years on LA treatment (y+1 to y+11). During the first two years of LA treatment (y+1 and y+2), a MACE reduction of 73 % was observed and continued to be low during y+3 to y+11, when all LA patients were analyzed. LA patients with only increased Lp(a) levels (Lp(a) ≥ 60 mg/dl (≥120 nmol/l) and an LDL-C < 100 mg/dl (<2.6 mmol/l)) had a higher MACE reduction (85 %; n = 443) in the first two years of LA treatment compared to LA patients with only increased LDL-C-levels (LDL-C ≥ 100 mg/dl (≥2.6 mmol/l); Lp(a) < 60 mg/dl (<120 nmol/l)) (53 %; n = 171). Adverse events of LA remained low (about 5 %) over the eleven years and mainly represented puncture problems (1.0 %). No side effects resulted in termination of LA therapy. The current analysis of GLAR data indicates that regular LA leads to very low incidence rates of cardiovascular events in patients with high LDL-C and/or high Lp(a) levels, progressive ASCVD, and maximally tolerated lipid-lowering medication, including proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibition. Additionally, LA was safe with a low rate of adverse effects over an 11-year period. The number of enrolled patients and the duration of observation establish GLAR as the largest LA registry worldwide.
