2015年9月28日，赛诺菲与再生元宣布欧盟委员会批准Praluent（alirocumab）用于某些高胆固醇血症成年患者的低密度脂蛋白（LDL）胆固醇治疗。
Praluent是欧盟委员会目前为止批准的唯一一款PCSK9（前蛋白转化酶枯草溶菌素 9）抑制剂，其以两种起始剂量为1mL的注射剂上市，每两周注射一次，它可以提供两种水平的疗效。Praluent将以单一剂量预填充笔形式上市，患者可自行注射。
两种不同Praluent剂强度可使医师调整治疗
两种不同剂量强度的Praluent提供了用药的灵活性。在临床实践中，这将使医师基于个体患者降低LDL胆固醇的需求调整治疗方案，法国第戎Point Medical的医学博士、哲学博士Farnier称。在3期试验中，大多数以较低的Praluent75mg 为起始剂量治疗的患者能够达到他们预设的LDL胆固醇目标，并在整个评价期内使用这一剂量能够获得维持治疗。
欧盟委员会批准Praluent作为饮食的一种辅助疗法用于原发性高胆固醇血症（杂合子家族性高胆固醇血症[HeFH] 及非家族性）或混合性血脂异常的治疗：
a) 与一种他汀药物或他汀药物加其它降脂药物联合用于使用最大耐受量他汀药物不能达到其LDL胆固醇目标的患者；
b) 单用或与其它降脂药物联合用于耐受他汀药物的患者，或用于对他汀药物禁忌的患者。Praluent对心血管（CV）发病率与死亡率的影响目前尚不能确定。
Praluent于7月份在美国获得批准
此次欧盟对这款药物的批准基于10关键3期ODYSSEY试验的数据，包括5项安慰剂对照试验及5项依折麦布（Ezetimibe）对照试验。数据表明，当添加到目前的标准治疗（包括最大耐受量的他汀药物）中时，与安慰剂或依折麦布相比，Praluent对LDL胆固醇显示出了一致的、强大的降低。
7月份，两家公司宣布Praluent在美国作为饮食及最大耐受量他汀药物的一种辅助治疗药物，获批用于需要额外降低LDL胆固醇的HeFH或临床动脉粥样硬化心血管疾病（ASCVD）成年患者治疗

Jul 15: US regulators have approved alirocumab (Praluent) for the treatment of high cholesterol, but for a narrower patient population than initially hoped. Specifically, the US FDA has approved its use alongside diet and maximum statin therapy in adults with heterozygous familial hypercholesterolaemia, or those with atherosclerotic cardiovascular disease such as heart attacks or strokes, who need additional lowering of LDL cholesterol. But the regulator has not cleared the drug to be used for patients deemed intolerant to statin therapy, because of uncertainty over the long-term benefit-risk equation for this group [29].
28/07/2015 15:52:04
Jul 15: EU positive opinion for use in adults with primary hypercholesterolaemia (heterozygous familial and non-familial) or mixed dyslipidaemia, as an adjunct to diet, in combination with a statin or statin with other lipid lowering therapies in patients unable to reach LDL-C goals with the maximum tolerated dose of a statin or, alone or in combination with other lipid-lowering therapies in patients who are statin-intolerant, or for whom a statin is contraindicated. The effect of Praluent on cardiovascular morbidity and mortality has not yet been determined [28].
24/07/2015 12:58:03

Nov 15: Sanofi and Regeneron announce a new post-hoc analysis of the 6 PIII ODYSSEY clinical trials (n=1291) showing that ~ 74% of pts reached their pre-specified LDL cholesterol targets within 8 weeks of adding Praluent® (alirocumab) injection 75 mg to their standard-of-care, which included statins. In the 26% of pts whose dose was increased to 150 mg, most were able to achieve their pre-specified LDL cholesterol target, with an average additional 14% reduction in LDL cholesterol. Comparable adverse event (AE) rates were observed in pts whose Praluent dose was increased, vs. those whose dose was not (66% in both arms in placebo-controlled trials; and 55% vs. 56% respectively in ezetimibe-controlled trials) [35].
12/11/2015 12:22:23
Sep 15: Results of ODYSEY FH1 and FHII published in the European Heart Journal. In patients with HeFH with inadequately controlled LDL-C levels despite maximally tolerated statin with or without other lipid lowering therapy, self-administered alirocumab reduced LDL-C from baseline by 57.9% (FH I study) and 51.4% (FH II study) v placebo at week 24 (p<0.001) [30].
04/09/2015 09:21:46
Jun 15: Results from ODYSSEY OPTIONS I (n=355) published in Journal of Clinical Endocrinology and Metabolism. Adding alirocumab to atorvastatin provided greater LDL-C reductions vs. adding ezetimibe, doubling atorvastatin dose, or switching to rosuvastatin (p<0.001 vs. all compatators), and enabled greater LDL-C goal achievement. Treatment-emergent adverse events occurred in 65.4% of alirocumab patients, vs 64.4% ezetimibe and 63.8% double atorvastatin/switch to rosuvastatin (data pooled) [28].
12/06/2015 11:13:21
Mar 15: ODYSSEY LONG TERM published in NEJM. At week 24, the difference between the alirocumab and placebo groups in the mean percentage change from baseline in calculated LDL cholesterol level was −62 percentage points (P<0.001); the treatment effect remained consistent over a period of 78 weeks. The alirocumab group, as compared with the placebo group, had higher rates of injection-site reactions (5.9% vs. 4.2%), myalgia (5.4% vs. 2.9%), neurocognitive events (1.2% vs. 0.5%), and ophthalmologic events (2.9% vs. 1.9%). In a post hoc analysis, the rate of major adverse cardiovascular events (death from coronary heart disease, nonfatal myocardial infarction, fatal or nonfatal ischemic stroke, or unstable angina requiring hospitalization) was lower with alirocumab than with placebo (1.7% vs. 3.3%; hazard ratio, 0.52; 95% confidence interval, 0.31 to 0.90; nominal P=0.02) [26].
18/03/2015 12:50:58
Feb 15. Results of the ODYSSEY COMBO II trial published in European Heart Journal. This RCT (n=720) reported a 50% reduction in LDL-C from 2.9 to 1.3 mmol/L for patients on alirocumab 75mg sc. every 2 weeks and a 20% reduction from 2.7 to 2.1 mmol/L for those on ezetimibe 10 mg daily (P<0.0001) at week 24 (primary efficacy endpoint). [25]
18/02/2015 14:55:10
Jan 15: The two ODYSSEY PIII trials designed to look at how alirocumab impacted patients with hypercholesterolemia when administered every four weeks met their primary endpoints. ODYSSEY CHOICE I looked at the efficacy and safety of alirocumab in 803 patients at moderate to high cardiovascular risk, while ODYSSEY CHOICE II examined it in patients with the same risk and a history of intolerance to two or more statins. In the monthly dosing trials, the mean percent reduction in LDL-C from baseline was consistent with that seen in previous PIII trials evaluating alirocumab every other week dosing. [22]
12/01/2015 12:42:34
Nov 14: Data from six PIII trials (ODYSSEY LONG TERM, COMBO I, ALTERNATIVE, OPTIONS I, OPTIONS II, and HIGH FH) of alirocumab presented at the American Heart Association (AHA). Pts all had high CV risk, heterozygous familial hypercholesterolemia (HeFH), and/or a history of intolerance to two or more statins. All the PIII trials were reported to have met their primary efficacy endpoints of significantly reduced LDL-C at 24 weeks compared with either active comparator or placebo. In addition, new interim results from ODYSSEY LONG TERM provide further support for alirocumab´s consistent safety profile. The company plans to file for approval by the end of the year [21].
20/11/2014 09:06:56
Nov 14: Data presented at the AHA congress. Among the 360 pts in a PIII study, those in the alirocumab arm reported a 45% LDL cholesterol reduction vs. 14.6% for subjects taking ezetimibe. Alirocumab helped 42% of pts get lower their LDL to target levels vs. 4% in the ezetimibe group [20].
19/11/2014 10:10:12
Aug 14: Results from 4 studies announced.

Nov 12: Results from a PII study published early online in N Engl J Med (October 31, 2012DOI: 10.1056/NEJMoa1201832). The study enrolled patients with primary hypercholesterolaemia with elevated LDL-C (≥100 mg/dL) who were on a stable 10mg dose of atorvastatin. The mean reduction in LDL-C after 8 weeks in patients who received alirocumab sc once every two weeks + atorvastatin 80mg was 73%, vs 17% in 17% for patients who switched to atorvastatin 80mg alone (p<0.001). 90% vs 17.2% of patients respectively, achieved a pre-specified level of 70mg/dL (p<0.001). In a third arm of the study in which alirocumab was added to the stable 10mg of atorvastatin, 96.6 achieved the pre-specified goal of 70mg/dL. The most common AEs reported in patients on alirocumab were headache, dizziness, and diarrhoea. There was one serious AE in the alirocumab + atorvastatin 80mg group (dehydration) that was deemed not to be treatment-related [10].

In the most intense dose regimen tested (150mg every two weeks), 93.8% of patients achieved LDL-C levels <2.59 mmol/L vs 13.3% of patients on placebo, and 81.3% reached LDL-C levels <1.81 mmol/L vs none on placebo. There were no serious adverse events on active treatment. No elevations in liver function tests >3 times the upper limit of normal and no cases of elevated creatinine kinase were reported. The most common adverse event reported was injection-site reaction [4].
29/05/2012 22:10:23
Mar 12: PII data presented at the American College of Cardiology´s 61st Annual Scientific Meeting in Chicago. The dose-finding study enrolled 183 pts with elevated LDL-C (greater than or equal to 100 mg/dL) despite being on a stable dose of atorvastatin. Across the five different dose regimens tested, pts receiving twice monthly SC injections of SAR236553 for 12 wks achieved & sustained a mean LDL-C reduction from baseline of 40% to 72%, vs. 5% in pts receiving placebo (p<0.0001). Pts in the study were followed for a total of 20 wks for safety. Most common adverse events (AEs) were injection site reactions. Serious AEs occurred in one pt receiving placebo & three pts in the active treatment arms, including a pt on active treatment who experienced a skin rash diagnosed as leukocytoclastic vasculitis. Six pts, all on active treatment, prematurely discontinued therapy due to AEs. Muscle complaints were infrequent & similar across all treatment gps. There were no significant elevations in liver enzymes or other lab values in pts on active treatment [2].
