Clinical efficacy and safety of achieving very low LDL-cholesterol concentrations with the PCSK9 inhibitor evolocumab: a prespecified secondary analysis of the FOURIER trial. The trial ran until at least 1,630 patients had a cardiovascular death, MI, or stroke. FOURIER is the first large trial to rigorously assess cardiovascular outcomes of a PCSK9 inhibitor, in this case Amgen’s evolocumab. Introduction to the Fourier Series The Fourier Series 4 of 28 The Designer’s Guide Community odic if it repeats itself identically after a period of time. As she told the New York Times, Amgen paid for the study, helped design it, collected the data and helped write the paper. 2019 Jan 1;4(1):59-63. doi: 10.1001/jamacardio.2018.4178. All Rights Reserved, This is a BETA experience. FOURIER was designed to find out. This study involved 27,564 patients with cardiovascular (CV) disease, 80% of whom had already experienced a heart attack. The calculation of the sample size was based on the postulated frequency of the key secondary end point. And before the “pharmascolds” begin their rants about conflicts of interest, one has to remember that a lot of these expensive, large clinical trials often result in failure. Fran ç ois Marie Charles Fourier, the French social critic, utopian socialist, and eccentric, was born into a merchant family in Besan ç on. FOURIER Trial Reviewed: Are the Expensive PCSK9 Inhibitors Right for Your Patients? It will be interesting to watch how the negotiations between Amgen and insurers unfold over the coming months. 2017 Oct 28;390(10106):1962-1971. doi: 10.1016/S0140-6736(17)32290-0. Thanks for visiting The Medical Bag. As it turns out the PCSK9 inhibitor saga ends not with a bang but a whimper. Lancet. Frankly, that’s absurd. In patients with established atherosclerotic heart disease, or diabetes with an additional risk factor, on pre-existing statin therapy with residual hypertriglyceridemia (fasting triglyceride level 135-499 mg/dL), does icosapent ethyl, a highly purified eicosapentaenoic acid ethyl ester, reduce cardiovascular events compared to placebo? They are, however, necessary to advance the field of medicine. FOURIER, FRAN Ç OIS MARIE CHARLES (1772 – 1837). researchers have an easier time showing a statistically significant difference between the treatment group and controls “If you had an LDL during the trial of less than 25 mg/dL, you were down-titrated from the 150-mg dose to the 75-mg dose, or if you were on the 75-mg dose with two consecutive LDLs less than 15 mg/dL, the alirocumab was stopped, all in blinded fashion.” A total of 27,564 individuals from 49 countries who had established atherosclerotic cardiovascular disease and LDL levels greater than or equal to 70 mg/dl, and who were already on statin therapy, were randomized to receive either evolocumab or a placebo. The integrity of these distinguished researchers shouldn’t be so easily dismissed by Dr. Redberg. The FOURIER trial compared evolocumab or matching placebo and followed up patients for a median of 2.2 years. There were high hopes for the FOURIER trial. George Marzouka, MD. There was a 62% reduction in LDL in these patients with no increase in cardiovascular events, and a post-hoc analysis showed a 2% absolute risk reduction in major cardiovascular events (MACE). Some experts, like Dr. Eugene Braunwald of Harvard Medical School, hailed these results: “This is like the era of statins coming in.” However, others are concerned over the costs of this drug. Results of the FOURIER trial were recently published in The New England Journal of Medicine, and the findings were presented at the American College of Cardiology 66th Annual Session & Expo (ACC.17) with mixed reviews.2. Monoclonal antibodies to PCSK9 are now available to treat patients at high atherosclerotic risk — either due to familial hypercholesterolemia with intact LDL receptors who would have otherwise needed plasmapheresis, or because of having LDL levels far above guideline limits despite maximal therapy with moderate- or high-intensity statins. The most eagerly awaited study presented at last week’s American College of Cardiology meeting was Amgen’s FOURIER clinical trial. Background: The proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor evolocumab reduced LDL cholesterol and cardiovascular events in the FOURIER trial. However, Dr. Rita Redberg, a cardiologist at the University of California, San Francisco, has a different concern about the FOURIER study and its results. What Dr. Redberg doesn’t mention is that Amgen did not design this trial in a vacuum; they did it in collaboration with expert cardiologists as well as the FDA. Criticism of capitalism comes from various political and philosophical approaches, including anarchist, socialist, religious and nationalist viewpoints. The trial differed from FOURIER by including participants with a recent acute coronary syndrome (ACS) event in the last 1-12 months (median 2.6 months since index ACS) rather than the more stable ASCVD population of FOURIER. 4. Yes, the data were collected by Amgen, but the data analyses were done independently by a team of academic researchers led by Dr. Marc Sabatine, chairman of the Thrombolysis and Myocardial Infarction Group at Brigham and Women’s Hospital. It was estimated that 1.630 such end-point events were required to provide a 90% power to detect a 15% relative reduction with evolocumab as … I am also a senior partner at PureTech Health. I was the president of Pfizer Global Research and Development in 2007 where I managed more than 13,000 scientists and professionals in the United States, Europe, and Asia.

The results of the highly anticipated FOURIER trial show that the drugs work, though not as powerfully as many had hoped and expected. Contribution To Literature: The FOURIER trial showed that evolocumab was superior to placebo at reducing adverse cardiovascular events. The most eagerly awaited study presented at last week’s American College of Cardiology meeting was Amgen’s FOURIER clinical trial. Because of the risks, these studies are undertaken with great care and with the advice and oversight of many outside of the company that is footing the bill for the study. Essays and criticism on Jonathan Beecher's Charles Fourier - Critical Essays. Dr. Redberg’s unfortunate comments play into the fears of those who believe that any science generated by the biopharmaceutical industry cannot be trusted. Several important cardiovascular prevention studies were presented at the 2019 AHA Scientific Sessions. I've received numerous awards including an Honorary Doctor of Science degree from the University of New Hampshire. The medical community as well as the FDA are grateful for these results as they add to our understanding of the role of LDL-c in CV disease. Repatha is expensive, with a list price of over $14,000 per year--although it is believed that payers have negotiated prices that are closer to $9,000/year. However, data supporting clinical outcomes with PCSK9-inhibitor use is lacking. Chicago, IL (updated) - The JUPITER trial is on the receiving end of an avalanche of criticism in four papers published in the June 28, 2010 issue of the Archives of Internal Medicine.

I cover news on drugs and R&D in the pharma industry, EY & Citi On The Importance Of Resilience And Innovation, Impact 50: Investors Seeking Profit — And Pushing For Change, Michigan Economic Development Corporation BrandVoice, the effects of bococizumab faded over time. JAMA Cardiol. Outcome studies such as these are among the riskiest in pharmaceutical R&D. Prior studies have shown that patients with angiographically established CAD who were already on chronic statin therapy and were randomized to receive treatment with PCSK9 inhibitors had significant plaque regression compared to the placebo group.1 However, translating those findings into clinical benefits on hard endpoints — such as cardiovascular death — has been difficult. You may opt-out by. Large, long-term trials have failed with other CV drugs like the CETP inhibitors, and even for drugs in other fields, particularly with Alzheimer’s disease drugs. The study was funded by Amgen. I am also the author of "Drug Truths: Dispelling The Myths Of R&D" and the recently published Devalued And Distrusted: Can The Pharmaceutical Industry Restore Its Broken Image?" here. Let the period be denoted T. Then mathematically, a T-periodic waveform v satisfies — a periodic waveform with period T (2) for all t.To make things simpler, let’s further assume that v is a continuous function of We hope you’re enjoying the latest health care news coverage, and lifestyle and business advice. In summary, it may be convenient to criticize FOURIER as a failure of genetic medicine, as the composite cardiovascular endpoint was less than what many had hoped and the current drug price is high. In this prespecified analysis of FOURIER, we investigated the efficacy and safety of evolocumab by diabetes status and the effect of evolocumab on glycaemia and risk of developing diabetes. The FOURIER trial also showed 1.5% absolute reduction in MACE when added to a high intensity statin with LDL above 70 mg/dL (Sabatine, 2017). She doesn’t mention that the study was carried out by investigators at leading teaching hospitals. The PCSK9 had only a 15% decrease in CV events, only half of what had been hoped. Design, setting, and participants: Secondary analysis of a randomized, double-blind clinical trial. Navigating the Unknown in The World of Lipid Management – Where are We Now? Current dogma is that the more you can lower your LDL cholesterol (LDL-c), the lower the risk of a heart attack or stroke. Registration is free. © 2020 Forbes Media LLC. In FOURIER median duration of follow-up of 26 months as opposed to approximately 4-year follow-up that was originally planned. At the current price of the drug, and lacking sufficient mortality data, treating patients for longer periods of time with expensive PCSK9 inhibitors is likely to result only in large profits. 27,000 patients with cardiovascular disease and already taking statins were randomized to evolocumab or placebo. However, it must be pointed out that the costs of such a study are beyond the means of the NIH or any other publicly funded institution. It shows that the benefits of LDL-c lowering may begin to level off at a certain point. Criticism of capitalism ranges from expressing disagreement with the principles of capitalism in its entirety to expressing disagreement with particular outcomes of capitalism.. Participants were monitored for a median follow-up period of only 2.2 years, despite original plans for 4 years of follow-up due to higher than expected​ event rates in the primary and secondary end-points. However, data supporting clinical outcomes with PCSK9-inhibitor use is lacking. Given the accrued benefits in risk reduction over time, one criticism of this trial is the short duration of follow-up. Coronary Artery Calcium Scores – A Marker for Early Adverse Events in Young Patients? Only the private sector has the funds needed to carry out such a large clinical trial. If you wish to read unlimited content, please log in or register below. Those patients taking optimal doses of statins had on average LDL-c levels of 92mg/dL, whereas those who were also dosed with Repatha had average LDL-c levels of 30mg/dL. The FOURIER trial previously established that, relative to placebo, evolocumab significantly reduced the first occurrence of the primary end point by 15% and the key secondary end point by 20%, but whether the benefit would be extended beyond the first event was unknown. However, don’t let those two critical issues muddle the importance of the trial itself and the impact on genetic-drive drug discovery. ...

Yes, Amgen did pay for this study–I would guess about $500 million or so. There's something for every health care professional on The Medical Bag. The question now will be whether the modest efficacy of the drugs is worth their immodest cost, at least for the vast majority of patients who are not at extreme high risk for … Clearly, Amgen’s actions must be scrutinized. FOURIER is one of the biggest randomized placebo-controlled trials on drug therapy so far performed. The goal was to show that Amgen’s drug, the PCSK9 inhibitor called Repatha, when added on top of statin therapy, further reduced CV events when compared to statin therapy alone. Epub 2017 Aug 28. In 2005, a loss-of-function mutation was found, supporting the concept that inhibitors of the enzyme could help lower LDL cholesterol and consequently reduce atherosclerotic cardio-vascular events. The goal of the trial was to provide some of the much-needed evidence regarding the risk reduction of cardiovascular events attributable to the addition of PCSK9 inhibitors to guideline-directed antilipid therapies, and to evaluate for potential side effects of very low LDL levels. Could a PCSK9 inhibitor be a major breakthrough against the world’s leading killer? Editorial, see p 150 Low-density lipoprotein cholesterol (LDL-C) has long been recognized as a risk factor for atherosclerotic cardiovascular disease.1 To that end, the cardiovascular benefit of LDL-C lowering has been demonstrated with multiple agents, including statins and nonstatin agents (eg, ezetimibe).2–4 Most recently, the FOURIER trial (Further Cardiovascular Outcomes Research With PCSK9 Inhibition in Patients With Elevated Risk) showed that the anti-PCSK9 (proprotein convertase subtilisin-kexin type 9) monoclo… “Some of that is just the way the study is set up, which is to ask people at the end of the trial, so it’s a little bit of an unfair criticism, I … 1. High Risk ASCVD This is not unique to PCSK9 clinical trials. A total of 27.564 were randomized to either evolocumab (13.784) or placebo (13.780). The mean baseline LDL-C was 92 mg/dL and the on-treatment LDL-C was 30 mg/dL, a reduction in mean LDL cholesterol of 59%. Please login or register first to view this content. Repatha did, in fact, produce unprecedented LDL-c lowering in FOURIER. There was no significant difference between study groups with regards to adverse events. Although FOURIER is a high-quality trial that conclusively demonstrates that lowering LDL with a PCSK9 inhibitor reduces CV risk, it's not clear from this study for whom this reduction is clinically important enough to justify the substantial cost of these drugs.

Long-term post-trial (legacy) beneficial effects have been reported with statins, niacin, hypoglycemic therapy and fibrates. Enjoying our content? The results of FOURIER vindicate those who opposed the treat-to-risk idea, and it probably brings back the practice of micromanagement of LDL-C levels.

All Rights Reserved Trial Design and Oversight The FOURIER trial was a randomized, double-blind, placebo-controlled, multinational clinical trial in which patients at 1242 sites in 49 coun- Dr. Redberg essentially believes that we shouldn’t accept the Amgen data at face value. However, translating those findings into clinical benefits on hard endpoints — such as cardiovascular death — has been difficult. FOURIER Basics. This observational study will follow participants who completed follow-up in the FOURIER OUTCOMES trial to evaluate the long-term effects of evolocumab treatment.

Responding to some of Robinson’s critiques about the patients who took the ECog surveys, Giugliano acknowledged that the patients who took the survey were at lower risk. This review highlights selected cardiovascular disease (CVD) prevention studies presented at the 2019 American Heart Association (AHA) Scientific Sessions. In late January, Pfizer had to stop the development of their own PCSK9 inhibitor, bococizumab, because their 32,000 patient SPIRE-1 and 2 studies showed that the effects of bococizumab faded over time. Except during the French Revolution, Charles Fourier led a quiet and isolated life as a minor business employee and bachelor in Paris, Lyons, Rouen, and elsewhere in France, with occasional trips abroad.
