Statin therapy seems safe in pregnancy
Statins may be safe when used during pregnancy, with no increase in risk for fetal anomalies, although there may be a higher risk for low birth weight and preterm labor, results of a large study from Taiwan suggest.
The Food and Drug Administration relaxed its warning on statins in July 2021, removing the drug’s blanket contraindication in all pregnant women.
Removal of the broadly worded contraindication should “enable health care professionals and patients to make individual decisions about benefit and risk, especially for those at very high risk of heart attack or stroke,” the FDA said in their announcement.
“Our findings suggested that statins may be used during pregnancy with no increase in the rate of congenital anomalies,” wrote Jui-Chun Chang, MD, from Taichung Veterans General Hospital, Taiwan, and colleagues in the new study, published online Dec. 30, 2021, in JAMA Network Open.
“For pregnant women at low risk, statins should be used carefully after assessing the risks of low birth weight and preterm birth,” they said. “For women with dyslipidemia or high-risk cardiovascular disease, as well as those who use statins before conception, statins may be continuously used with no increased risks of neonatal adverse effects.”
The study included more than 1.4 million pregnant women aged 18 years and older who gave birth to their first child between 2004 and 2014.
A total of 469 women (mean age, 32.6 years; mean gestational age, 38.4 weeks) who used statins during pregnancy were compared with 4,690 matched controls who had no statin exposure during pregnancy.
After controlling for maternal comorbidities and age, women who used statins during pregnancy were more apt to have low-birth-weight babies weighing less than 2,500 g (risk ratio, 1.51; 95% confidence interval, 1.05-2.16) and to deliver preterm (RR, 1.99; 95% CI, 1.46-2.71).
The statin-exposed babies were also more likely to have a lower 1-minute Apgar score (RR, 1.83; 95% CI, 1.04-3.20). Importantly, however, there was no increase in risk for fetal anomalies in the statin-exposed infants, the researchers said.
In addition, for women who used statins for more than 3 months prior to pregnancy, maintaining statin use during pregnancy did not increase the risk for adverse neonatal outcomes, including congenital anomalies, low birth weight, preterm birth, very low birth weight, low Apgar scores, and fetal distress.
The researchers called for further studies to confirm their observations.
Funding for the study was provided by Taichung Veterans General Hospital. The authors have disclosed no relevant financial relationships.

FDA approves first-in-class inclisiran to lower LDL-C
The Food and Drug Administration has approved inclisiran (Leqvio) as an adjunct to statins for further reduction of LDL cholesterol levels, the drug’s developer, Novartis, announced on Dec. 22, 2021.
The first-in-class small interfering RNA (siRNA) agent is also novel among peer drug therapies for its administration by injection initially, at 3 months, and thereafter twice per year.
Inclisiran is indicated for use atop maximally tolerated statins in adults with clinical cardiovascular disease or in patients with heterozygous familial hypercholesterolemia, the company reported.
Such patients who received inclisiran, compared with placebo, in the ORION-9, ORION-10, and ORION-11 randomized trials on which the FDA approval was based showed LDL-C reductions exceeding 50% over 1-2 years.
The drug works by “silencing” RNA involved in synthesis of PCSK9, which has a role in controlling the number of LDL cholesterol cell-surface receptors, a unique mechanism of action among available treatments for dyslipidemia.
Novartis, the company said, “has obtained global rights to develop, manufacture, and commercialize Leqvio under a license and collaboration agreement with Alnylam Pharmaceuticals.”

Last call? Moderate alcohol’s health benefits look increasingly doubtful
When holiday shoppers recently went to their local liquor stores in search of some liquid spirit, many were instead greeted by the sight of increasingly barren shelves.
Although partly a result of global supply chain issues, this was also yet more evidence of the rising demand for alcohol among adults during these difficult COVID years. It’s a trend that has led to concerns of an echo pandemic of alcohol-related morbidity, which has begun to play out in the form of rising rates of gastrointestinal and liver disease, hospital admissions for alcoholic hepatitis, and alcohol-related incidents of domestic violence.
Those who imbibe alcohol in low to moderate levels may not see themselves reflected in such stories of drinking’s hefty tolls. They’re instead following established health guidance that a little bit of alcohol now and then actually has robust health benefits. Yet the past few of years have seen a notable fraying of this idea, as emerging data calls into question whether alcohol in moderation should really continue to be just what the doctor ordered.
Behind the curve: Alcohol’s diminishing cardioprotective value
Perhaps the most resonant argument for the benefits of light to moderate alcohol consumption – usually defined as between one to two drinks a day – has been its proposed cardioprotective value. In this way, alcohol differs from tobacco, which is unsafe at any level. Alcohol’s proposed cardioprotective effects are often represented as a J-shaped curve, with moderate drinking occupying the sweet spot between teetotaling and heavy/binge drinking when it comes to reduced mortality.
In reality, this association is more likely “a statistical artifact” largely derived from low-quality observational studies, according to Christopher Labos, MD, CM, MSc, an epidemiologist and cardiologist at the Queen Elizabeth Health Complex in Montreal.
“When you look at studies that correct for things like reverse causation, or the fact that some people who drink zero alcohol are former drinkers who used to drink alcohol, then you realize that the protective benefit of alcohol is either minimal or nonexistent and that alcohol does more harm than good to our society,” said Dr. Labos, who detailed the reasons underpinning alcohol’s unearned cardioprotective reputation in a 2020 Medscape commentary.
This statistical limitation was on display in July 2021 when BMC Medicine published results from meta-analyses suggesting that current drinkers need not stop consuming small amounts of alcohol for the secondary prevention of cardiovascular disease (CVD). The study’s own investigators noted that it likely overestimated the reduced risk of CVD by including former heavy drinkers as nondrinkers.
Even if the J-shaped curve exists, its simplicity is deceiving. CVD risk increases alongside alcohol consumption owning to a complicated array of genetic and lifestyle factors. The curve also presents something of a catch-22. If you like alcohol enough to drink it every day, staying at the nadir of the curve where you’d gain the most benefits may prove challenging.
Another factor dimming alcohol’s cardioprotective reputation came via recent data that atrial fibrillation episodes can be triggered by acute alcohol use. A randomized, controlled trial published in the New England Journal of Medicine concluded that abstinence reduced arrhythmia recurrences in regular drinkers with atrial fibrillation.
“If we can replicate that, I think we’ll find that reducing alcohol consumption might be a very effective way to prevent and treat atrial fibrillation,” said Dr. Labos.
However, J-curve proponents will note the publication of study data from the UK Biobank indicating that low levels of alcohol consumption confers the greatest reduction in atrial fibrillation risk.
An overlooked carcinogen no longer
Surveys indicate that less than half of Americans realize alcohol increases cancer risk. That might have changed just a bit this year. In early 2021, an epidemiological analysis estimated that alcohol contributed to 4.8% of cancer cases and 3.2% of cancer deaths in the United States. Then the Lancet Oncology published the results of a high-profile, population-based study on the global burden of cancer as a result of alcoho. Although the main takeaway message was that 4% of new cancer cases worldwide in 2020 were attributable to alcohol, it was also noteworthy that moderate drinking accounted for 103,100 out of 741,300 of these projected annual cases.
“The risk of cancer increases even with low or moderate levels of drinking,” said the study’s lead author Harriet Rumgay, BSc, from the International Agency for Research on Cancer in Lyon, France. “Drinking less means you’ll have a lower risk of cancer than if you drink heavily, but there is no safe limit of alcohol consumption.”
The study linked alcohol consumption with an increased risk of at least seven different cancer types, including cancers of the oral cavity, pharynx, larynx, esophagus, colon, rectum, liver, and breast.
Although in North America men represented about two-thirds of the burden of cancer caused by alcohol, Ms. Rumgay added that “low and moderate levels of drinking [one or two alcoholic drinks per day] contributed relatively more cancer cases among women than among men.”
Yet more negative news for moderate alcohol drinkers arrived in August 2021, when a team of South Korean researchers published data in JAMA Network Open showing that, when it came to the risk of developing gastrointestinal cancers, even binge drinking may be preferable to continuous but moderate consumption.
who in updating its guidelines in 2020 after an 8-year interim offered this succinct piece of advice: “It is best not to drink alcohol.”
Neurotoxic implications
There has similarly been a reconsideration of the effects of moderate alcohol consumption on brain health.
A recent report of multimodal MRI brain and cognitive testing data from over 25,000 participants in the UK Biobank study indicate that alcohol may have no safe dosage . Even moderate consumption reduced gray matter volume and functional connectivity, negative associations that were increased in those with higher blood pressure and body mass index.
Speaking with this news organization in May 2021, an investigator said: “The size of the effect is small, albeit greater than any other modifiable risk factor,” noting that the changes have been linked to decreased memory and dementia.
Louise Mewton, PhD, from the Center for Healthy Brain Aging at the University of New South Wales, Sydney, said that these results provide an interesting comparison with others into the association between alcohol and dementia.
“A recent study of over 1 million dementia cases in France indicated that problematic alcohol use (alcohol use disorders) were one of the strongest risk factors for dementia – even more so than things like high blood pressure and diabetes,” Dr. Mewton said in an interview. In comparison, “the most-recent reviews indicate that 4 drinks/week is associated with the lowest risk for dementia – so we’re talking about very low levels of alcohol use in terms of maintaining brain health.
“Understanding why very small amounts of alcohol appear to be protective in terms of dementia but damaging when we look at brain scans is something that would be really interesting to unpack.”
Dr. Mewton and colleagues recently published data suggesting that there are three periods when the brain might be particularly susceptible to alcohol’s neurotoxic effects: gestation (from conception to birth), later adolescence (15-19 years), and older adulthood (over 65 years). Directing behavioral interventions to patients in these stages may therefore be beneficial.
And there’s no time too soon to promote abstinence among those with alcohol use disorder, as brain damage is shown to still occur even in the immediate period after people cease drinking.
Although in one more argument for the J-shaped curve’s relevance, data from the Massachusetts General Brigham Biobank recently indicated that moderate alcohol use, unlike low and heavy use, lowered both stress-related neurobiological activity and major adverse cardiovascular events.
Getting patients to reconsider alcohol’s ‘benefits’
These new findings mean physicians will find themselves imparting a more nuanced message about the health impacts of moderate alcohol consumption than in prior years. To aid those efforts, Ms. Rumgay advised clinicians to consult a special issue of the journal Nutrients that features review articles of alcohol›s impact on various health outcomes.
Ms. Rumgay also supports broader policy changes.
“There is some evidence that adding cancer warnings to alcohol labels, similar to those used on cigarette packages, might deter people from purchasing alcohol products and increase awareness of the causal link with cancer,” she said. “But the most effective ways of reducing alcohol use in the population are through increasing the price of alcohol through higher taxes, limiting purchasing availability, and reducing marketing of alcohol brands to the public.”
Dr. Mewton recommended various interventions for patients who still find it difficult to curtail their drinking.
“For less severe, problematic use, things like cognitive-behavioral therapy and motivational therapy are very effective in reducing alcohol consumption,” she said in an interview.
For all the discussion about how the COVID-19 pandemic has exacerbated problematic drinking, it has also provided an opportunity for getting patients to reexamine their relationship to alcohol. And as Dr. Labos noted, emerging data on alcohol’s negative effects probably won’t be considered earth-shattering to most patients.
“Deep down, I think most people know that alcohol is not healthy, but it is part of our social culture and so we find ways to justify our own behavior,” he said in an interview.
Dr. Labos suggested that clinicians reframe alcohol in their patients’ minds for what it really is – “an indulgence that we shouldn’t have too much of very often.
“Just like junk food, that doesn’t mean we can’t enjoy small amounts occasionally, but we have to stop presenting that it is good for us, because it isn’t.”

Yet more negative news for moderate alcohol drinkers arrived in August 2021, when a team of South Korean researchers published data in JAMA Network Open showing that, when it came to the risk of developing gastrointestinal cancers, even binge drinking may be preferable to continuous but moderate consumption.
who in updating its guidelines in 2020 after an 8-year interim offered this succinct piece of advice: “It is best not to drink alcohol.”
Neurotoxic implications
There has similarly been a reconsideration of the effects of moderate alcohol consumption on brain health.
A recent report of multimodal MRI brain and cognitive testing data from over 25,000 participants in the UK Biobank study indicate that alcohol may have no safe dosage . Even moderate consumption reduced gray matter volume and functional connectivity, negative associations that were increased in those with higher blood pressure and body mass index.
Speaking with this news organization in May 2021, an investigator said: “The size of the effect is small, albeit greater than any other modifiable risk factor,” noting that the changes have been linked to decreased memory and dementia.
Louise Mewton, PhD, from the Center for Healthy Brain Aging at the University of New South Wales, Sydney, said that these results provide an interesting comparison with others into the association between alcohol and dementia.
“A recent study of over 1 million dementia cases in France indicated that problematic alcohol use (alcohol use disorders) were one of the strongest risk factors for dementia – even more so than things like high blood pressure and diabetes,” Dr. Mewton said in an interview. In comparison, “the most-recent reviews indicate that 4 drinks/week is associated with the lowest risk for dementia – so we’re talking about very low levels of alcohol use in terms of maintaining brain health.
“Understanding why very small amounts of alcohol appear to be protective in terms of dementia but damaging when we look at brain scans is something that would be really interesting to unpack.”
Dr. Mewton and colleagues recently published data suggesting that there are three periods when the brain might be particularly susceptible to alcohol’s neurotoxic effects: gestation (from conception to birth), later adolescence (15-19 years), and older adulthood (over 65 years). Directing behavioral interventions to patients in these stages may therefore be beneficial.
And there’s no time too soon to promote abstinence among those with alcohol use disorder, as brain damage is shown to still occur even in the immediate period after people cease drinking.
Although in one more argument for the J-shaped curve’s relevance, data from the Massachusetts General Brigham Biobank recently indicated that moderate alcohol use, unlike low and heavy use, lowered both stress-related neurobiological activity and major adverse cardiovascular events.
Getting patients to reconsider alcohol’s ‘benefits’
These new findings mean physicians will find themselves imparting a more nuanced message about the health impacts of moderate alcohol consumption than in prior years. To aid those efforts, Ms. Rumgay advised clinicians to consult a special issue of the journal Nutrients that features review articles of alcohol›s impact on various health outcomes.
Ms. Rumgay also supports broader policy changes.
“There is some evidence that adding cancer warnings to alcohol labels, similar to those used on cigarette packages, might deter people from purchasing alcohol products and increase awareness of the causal link with cancer,” she said. “But the most effective ways of reducing alcohol use in the population are through increasing the price of alcohol through higher taxes, limiting purchasing availability, and reducing marketing of alcohol brands to the public.”
Dr. Mewton recommended various interventions for patients who still find it difficult to curtail their drinking.
“For less severe, problematic use, things like cognitive-behavioral therapy and motivational therapy are very effective in reducing alcohol consumption,” she said in an interview.
For all the discussion about how the COVID-19 pandemic has exacerbated problematic drinking, it has also provided an opportunity for getting patients to reexamine their relationship to alcohol. And as Dr. Labos noted, emerging data on alcohol’s negative effects probably won’t be considered earth-shattering to most patients.
“Deep down, I think most people know that alcohol is not healthy, but it is part of our social culture and so we find ways to justify our own behavior,” he said in an interview.
Dr. Labos suggested that clinicians reframe alcohol in their patients’ minds for what it really is – “an indulgence that we shouldn’t have too much of very often.
“Just like junk food, that doesn’t mean we can’t enjoy small amounts occasionally, but we have to stop presenting that it is good for us, because it isn’t.”

Fish oil: ‘No net benefit’ for depression prevention?
Fish oil supplementation does not help prevent depression or boost mood, new research suggests.
The VITAL-DEP study included more than 18,000 participants. Among adults aged 50 years or older free of clinically relevant depressive symptoms at baseline, long-term use of marine omega-3 fatty acid (omega-3) supplements did not reduce risk for depression or clinically relevant depressive symptoms — or make a difference in the quality of mood.
“While a small increase in risk of depression was inside the statistical margin of significance, there was no harmful or beneficial effect of omega-3 on the overall course of mood during the roughly 5 to 7 years of follow-up,” lead author Olivia I. Okereke, MD, Massachusetts General Hospital and Harvard Medical School, Boston, told Medscape Medical News.
“The takeaway from our study is that there is no net benefit of long-term use of daily omega-3 fish oil supplements for preventing depression or boosting mood,” Okereke said.
The findings were published online Dec. 21 in JAMA.
Assessing general population risk
For many years, experts have recommended omega-3 supplements for reduction in depression recurrence in some high-risk patients, Okereke noted.
“However, there are no guidelines related to the use of omega-3 supplements for preventing depression in the general population. Therefore, we undertook this study to provide clarity in the issue,” she said.
The VITAL-DEP study enrolled 18,353 older adults (mean age, 67.5 years; 49% women). Of these, 16,657 were at risk for incident depression, defined as having no previous history of depression; and 1696 were at risk for recurrent depression, defined as having a history of depression but not having undergone treatment for depression within the past 2 years.
Roughly half the participants were randomly assigned to receive marine omega-3 fatty acids (1 g/d of fish oil, including 465 mg of eicosapentaenoic acid [EPA] and 375 mg of docosahexaenoic acid [DHA]) and the other half to matching placebo for an average of 5.3 years.
“Because of the large sample size and long follow-up, we were able to test the effects of daily omega-3 fish oil supplements on universal prevention of depression in the adult population,” Okereke said.
No significant benefit
Results showed risk for depression or clinically relevant depressive symptoms (total of incident and recurrent cases) was not significantly different between the omega-3 group and the placebo group.
The omega-3 group had 651 depression or clinically relevant depressive symptom events (13.9 per 1000 person-years), and the placebo group had 583 depression or clinically relevant depressive symptom events (12.3 per 1000 person-years). The hazard ratio was 1.13 (95% CI, 1.01 - 1.26; P = .03).
There were also no significant between-group differences in longitudinal mood scores. The mean difference in change in 8-item Patient Health Questionnaire (PHQ-8) score was 0.03 points (95% CI, −0.01 to 0.07; P = .19).
“Patients, physicians, and other clinicians should understand that there are still many reasons for some people, under the guidance of their health care providers, to take omega-3 fish oil supplements,” Okereke noted.
“These supplements increasingly have been found to have benefits for cardiac disease prevention and treatment of inflammatory conditions, in addition to being used for management of existing depressive disorders in some high-risk patients,” she said.
“However, the results of our study indicate there is no reason for adults in the general population to be taking daily omega-3 fish oil supplements solely for the purpose of preventing depression or for maintaining a positive mood,” she added.
Okereke noted, however, that the VITAL-DEP study used 1 g/day of omega-3 fatty acids and there may be a greater benefit from taking higher doses, such as 4 g/day.
Cautionary notes
Commenting on the study for Medscape Medical News, Kuan-Pin Su, MD, PhD, chief of the Department of General Psychiatry, China Medical University, Taichung, Taiwan, highlighted some of the limitations cited by the investigators.
First, depression or depressive symptoms were defined using self-rating scales, which are “convenient to screen for depressive disorders, but a high score obtained on a self-rating scale does not necessarily indicate the presence of depressive psychopathology,” said Su, who was not involved with the research.
He also noted that use of 465 mg of EPA and 375 mg of DHA in VITAL-DEP “might be too low” to have an impact.
Finally, Su said it is “very important to also address the potential for type I error, which makes the secondary and subgroup analyses less reliable.”
VITAL-DEP was supported by a grant from the National Institute of Mental Health. Pronova BioPharma donated the fish oil and matching placebo. Okereke reported receiving royalties from Springer Publishing. Su is a founding committee member of the International Society for Nutritional Psychiatry Research, the board director of the International Society for the Study of Fatty Acids, and an associate editor of the journal Brain, Behavior, and Immunity.

Visceral fat may help ID heart risk in obese youth
The amount of fat surrounding abdominal organs may help clinicians identify cardiovascular risk in young people with obesity, researchers have found.
Severely overweight children and young adults showed a subtle association between visceral fat and arterial stiffness independent of body mass index (BMI). The association was not present in those of healthy weight, possibly because their visceral fat stores are too small to have a detectable effect on cardiovascular health, according to the researchers, who reported their findings in the latest issue of Pediatric Obesity.
“Those kids with greater visceral fat had stiffer arteries, which can overtax and overstress the system and lead to unfortunate consequences in terms of cardiovascular health down the line,” senior author Joseph M. Kindler, PhD, an assistant professor of nutritional sciences at the University of Georgia, Athens, told this news organization.
The data came from cross-sectional measurements in 605 youth (67% female, 56% non-Black) aged 10-23 years at Cincinnati Children’s Hospital Medical Center. The sample included 236 individuals of healthy weight, 224 with obesity, and 145 with type 2 diabetes.
Visceral fat was assessed with dual-energy x-ray absorptiometry (DXA), a widely used test of bone mineral density screening to assess fracture risk. Carotid-femoral pulse wave velocity (PWV) was used to gauge arterial stiffness, a subclinical sign of cardiovascular disease.
Visceral fat was associated with PWV in all three groups of study subjects (P < .05), the researchers found, whereas the amount of subcutaneous fat was linked to arterial stiffness in obese youth and those with obesity but not those whose weight was considered healthy.
The amount of fat was associated with an additional 1.6% of the variability in arterial stiffness in youth with obesity after accounting for BMI. Subcutaneous fat, meanwhile, did not appear to affect PWV, the researchers found. “In youth with healthy weight, visceral fat, subcutaneous fat, BMI, and waist circumference were not significantly associated with PWV in any analyses,” they write.
The researchers cited a paucity of data on the relationship between visceral fat and cardiovascular disease in children with obesity. Although BMI is a reliable and readily available indicator of risk for disease, DXA “might give us a little more information,” Dr. Kindler, a nutritionist and bone biologist, said. As for clinical use to supplement BMI and waist circumference, he said, “maybe there’s room for visceral fat, but we do need a lot more science to back those decisions down the line.”
For example, what normal visceral fat accumulation during childhood looks like is unknown, he said.
Rigorous longitudinal studies are needed to establish cause and effect, but the new findings offer “a potential connection between visceral fat and cardiovascular disease risk in youth in a relatively large sample,” Wei Shen, MD, MPH, the associate director of the body composition unit at the New York Obesity Nutrition Research Center at Columbia University, New York, said.
Ideally, said Dr. Shen, who was not involved in the latest study, it would be “more credible to use the most accurate measure of visceral fat, the volumetric measurement of visceral fat using MRI” to establish a causal relationship with cardiovascular risk. However, MRI is more expensive and less accessible than DXA. To assess visceral fat in the clinic, “waist circumference may still be a good choice, as it is so convenient to use,” she added.
Dr. Kindler and his colleagues highlighted the need to examine the effect of excess visceral fat as well as intrahepatic fat on youth with type 2 diabetes, who experience cardiovascular complications independent of whether they are obese. In the new study, the positive association between visceral fat and arterial stiffness did not differ between youth with obesity and normal glucose control and those with obesity and type 2 diabetes.
Funding came from the Endocrine Fellows Foundation, the National Institutes of Health, and the University of Georgia Obesity Initiative. Dr. Kindler and Dr. Shen have disclosed no relevant financial relationships.

Metabolites implicated in CHD development in African Americans
Selected metabolic biomarkers may influence disease risk and progression in African American and White persons in different ways, a cohort study of the landmark Jackson Heart Study has found.
The investigators identified 22 specific metabolites that seem to influence incident CHD risk in African American patients – 13 metabolites that were also replicated in a multiethnic population and 9 novel metabolites that include N-acylamides and leucine, a branched-chain amino acid.
“To our knowledge, this is the first time that an N-acylamide as a class of molecule has been shown to be associated with incident coronary heart disease,” lead study author Daniel E. Cruz, MD, an instructor at Harvard Medical School in the division of cardiovascular medicine at Beth Israel Deaconess Medical Center in Boston, said in an interview.
The researchers analyzed targeted plasma metabolomic profiles of 2,346 participants in the Jackson Heart Study, a prospective population-based cohort study in the Mississippi city that included 5,306 African American patients evaluated over 15 years. They then performed a replication analysis of CHD-associated metabolites among 1,588 multiethnic participants in the Women’s Health Initiative, another population-based cohort study that included 161,808 postmenopausal women, also over 15 years. In all, the study, published in JAMA Cardiology, identified 46 metabolites that were associated with incident CHD up to 16 years before the incident event
Dr. Cruz said the “most interesting” findings were the roles of the N-acylamide linoleoyl ethanolamide and leucine. The former is of interest “because it is a lipid-signaling molecule that has been shown to have anti-inflammatory effects on macrophages; the influence and effects on macrophages are of particular interest because of macrophages’ central role in atherosclerosis and coronary heart disease,” he said.
Leucine draws interest because, in this study population, it was linked to a reduced risk of incident CHD. The researchers cited four previous studies in predominantly non-Hispanic White populations that found no association between branched-chain amino acids and incident CHD in Circulation, Stroke Circulation: Genomic and Precision Medicine, and Atherosclerosis. Other branched-amino acids included in the analysis trended toward a decreased risk of CHD, but those didn’t achieve the same statistical significance as that of leucine, Dr. Cruz said.
“In some of the analyses we did, there was a subset of metabolites that the associations with CHD appeared to be different between self-identified African Americans in the Jackson cohort vs. self-identified non-Hispanic Whites, and leucine was one of them,” Dr. Cruz said.
He emphasized that this study “is not a genetic analysis” because the participants self-identified their race. “So our next step is to figure out why this difference appears between these self-identified groups,” Dr. Cruz said. “We suspect environmental factors play a role – psychological stress, diet, income level, to name a few – but we are also interested to see if there are genetic causes.”
The results “are not clinically applicable,” Dr. Cruz said, but they do point to a need for more ethnically and racially diverse study populations. “The big picture is that, before we go implementing novel biomarkers into clinical practice, we need to make sure that they are accurate across different populations of people,” he said. “The only way to do this is to study different groups with the same rigor and vigor and thoughtfulness as any other group.”
These findings fall in line with other studies that found other nonmetabolomic biomarkers have countervailing effects on CHD risk in African Americans and non-Hispanic Whites, said Christie M. Ballantyne, MD, chief of cardiology at Baylor College of Medicine in Houston. For example, African Americans have been found to have lower triglyceride and HDL cholesterol levels than those of Whites.
The study “points out that there may be important biological differences in the metabolic pathways and abnormalities in the development of CHD between races,” Dr. Ballantyne said. “This further emphasizes both the importance and challenge of testing therapies in multiple racial/ethnic groups and with more even representation between men and women.”
Combining metabolomic profiling along with other biomarkers and possibly genetics may be helpful to “personalize” therapies in the future, he added.
Dr. Cruz and Dr. Ballantyne have no relevant relationships to disclose.
Selected metabolic biomarkers may influence disease risk and progression in African American and White persons in different ways, a cohort study of the landmark Jackson Heart Study has found.
The investigators identified 22 specific metabolites that seem to influence incident CHD risk in African American patients – 13 metabolites that were also replicated in a multiethnic population and 9 novel metabolites that include N-acylamides and leucine, a branched-chain amino acid.
“To our knowledge, this is the first time that an N-acylamide as a class of molecule has been shown to be associated with incident coronary heart disease,” lead study author Daniel E. Cruz, MD, an instructor at Harvard Medical School in the division of cardiovascular medicine at Beth Israel Deaconess Medical Center in Boston, said in an interview.
The researchers analyzed targeted plasma metabolomic profiles of 2,346 participants in the Jackson Heart Study, a prospective population-based cohort study in the Mississippi city that included 5,306 African American patients evaluated over 15 years. They then performed a replication analysis of CHD-associated metabolites among 1,588 multiethnic participants in the Women’s Health Initiative, another population-based cohort study that included 161,808 postmenopausal women, also over 15 years. In all, the study, published in JAMA Cardiology, identified 46 metabolites that were associated with incident CHD up to 16 years before the incident event
Dr. Cruz said the “most interesting” findings were the roles of the N-acylamide linoleoyl ethanolamide and leucine. The former is of interest “because it is a lipid-signaling molecule that has been shown to have anti-inflammatory effects on macrophages; the influence and effects on macrophages are of particular interest because of macrophages’ central role in atherosclerosis and coronary heart disease,” he said.
Leucine draws interest because, in this study population, it was linked to a reduced risk of incident CHD. The researchers cited four previous studies in predominantly non-Hispanic White populations that found no association between branched-chain amino acids and incident CHD in Circulation, Stroke Circulation: Genomic and Precision Medicine, and Atherosclerosis. Other branched-amino acids included in the analysis trended toward a decreased risk of CHD, but those didn’t achieve the same statistical significance as that of leucine, Dr. Cruz said.
“In some of the analyses we did, there was a subset of metabolites that the associations with CHD appeared to be different between self-identified African Americans in the Jackson cohort vs. self-identified non-Hispanic Whites, and leucine was one of them,” Dr. Cruz said.
He emphasized that this study “is not a genetic analysis” because the participants self-identified their race. “So our next step is to figure out why this difference appears between these self-identified groups,” Dr. Cruz said. “We suspect environmental factors play a role – psychological stress, diet, income level, to name a few – but we are also interested to see if there are genetic causes.”
The results “are not clinically applicable,” Dr. Cruz said, but they do point to a need for more ethnically and racially diverse study populations. “The big picture is that, before we go implementing novel biomarkers into clinical practice, we need to make sure that they are accurate across different populations of people,” he said. “The only way to do this is to study different groups with the same rigor and vigor and thoughtfulness as any other group.”

New CETP inhibitor impresses in LDL lowering
A new lipid-lowering agent in a class that had been written off by many is being developed by a group of academic experts, with new data showing large LDL reductions on top of high-intensity statins.
Obicetrapib is a member of the cholesteryl ester transfer protein (CETP) inhibitor class, which had fallen out of favor after several disappointments with previous drugs in this class.
These agents were initially developed for their ability to raise HDL cholesterol, which was thought to be beneficial. But that approach has now been virtually abandoned after several studies failed to show a link between raising HDL and a reduction in subsequent cardiovascular events.
However, obicetrapib, which is said to be the most potent CETP inhibitor to date, has been shown to produce impressive LDL reductions, and it’s this important data that has caused several lipid experts to want to continue its development.
New data, presented at the recent American Heart Association scientific sessions, show that obicetrapib reduces LDL by 50% when given in addition to high-intensity statins, which could place it as competition for PCSK9 inhibitors or the new agent, inclisiran, but with the advantage of oral dosing.
The drug was in development by Amgen, but the company decided to discontinue its development in 2017 after disappointing results had been seen with several other CETP inhibitors and interest in this class of agent was waning.
But academic experts in the lipid field, led by John Kastelein, MD, PhD, professor of medicine at the Academic Medical Center, University of Amsterdam, and Michael Davidson, MD, clinical professor of medicine at University of Chicago, believed the drug had potential and have acquired obicetrapib from Amgen.
Dr. Kastelein and Dr. Davidson have set up a new company – New Amsterdam Pharma – to further develop obicetrapib, and have raised $200 million from venture capital funding to complete phase 2 and phase 3 studies.
The company has a heavyweight academic advisory board including Stephen Nicholls, MD, Monash University, Clayton, Australia; Kausik Ray, MD, Imperial College London; and Christie Ballantyne, MD, Baylor College of Medicine, Houston.
“We wanted to develop obicetrapib further because of its amazing LDL-lowering properties,” Dr. Kastelein said in an interview.
“No one has paid much attention to CETP inhibitors after the HDL hypothesis was disregarded, as everyone thought these drugs were just about raising HDL. But actually, they can also lower LDL, and this particular agent reduces LDL very effectively,” Dr. Kastelein said.
ROSE study
Dr. Nicholls presented the latest data on obicetrapib at the AHA meeting.
“Despite the use of high-intensity statins, two-thirds of patients do not reach their target LDL level, so we have a need for new therapies that lower LDL and can be used in combination with high-intensity statins,” he explained.
He noted that earlier studies with obicetrapib showed a 45% lowering of LDL with monotherapy.
Dr. Nicholls reported that recent evidence has emerged that increases interest in inhibiting CETP to be potentially cardioprotective.
To begin, genetic studies have shown that genetic polymorphisms associated with lower levels of CETP appear to be cardioprotective, and this is associated with lower levels of LDL rather than higher levels of HDL.
Furthermore, the REVEAL cardiovascular outcomes trial with anacetrapib (also a CETP inhibitor) in 2017 showed a significant 9% reduction in major adverse cardiac events (MACE) after 4 years of follow-up. “This was exactly predicted by the 11 mg/dL drop in absolute LDL cholesterol level. It was not predicted or associated with the increase in HDL level observed with that agent,” Dr. Nicholls said.
The objective of the current ROSE study was to evaluate the lipid-lowering ability, safety, and tolerability of obicetrapib in patients on high-intensity statins.
The study included 120 patients who had been treated on a stable dose of high-intensity statins (atorvastatin at a dose of at least 40 mg daily or rosuvastatin at a dose of 20 mg daily) for at least 8 weeks. All patients were required to have a fasting LDL of at least 70 mg/dL and the median baseline LDL was 90 mg/dL. They were randomly assigned to obicetrapib (5 mg or 10 mg daily) or placebo.
The primary endpoint was the difference between groups in percentage change in LDL from baseline to week 8, with LDL levels measured by two different techniques.
Results showed a “robust” 51% reduction in LDL with the 10-mg dose of obicetrapib, and a 42% reduction with the 5-mg dose, Dr. Nicholls reported.
These effects were comparable regardless of baseline LDL and were similar with both methods of LDL measurement.
Almost all patients demonstrated some degree of LDL cholesterol lowering, with only three patients on the 5-mg dose and one patient on the 10-mg dose not showing any reduction in LDL.
Other results showed a dose-dependent lowering of Apo B of up to 30%, and a reduction of non-HDL cholesterol of up to 44%.
“Predictably, there were also increases of HDL cholesterol,” Dr. Nicholls said. “At the 10-mg dose, we see a 165% increase in HDL levels. That is associated with a 48% increase in Apo A1 levels. This is very consistent with findings from the previous monotherapy study.”
There was a 56% reduction in Lp(a) levels, and a modest 11% reduction in triglycerides.
Both doses of obicetrapib were well tolerated, with no increase in the rate of adverse events. Only one patient discontinued the study drug because of an adverse event and that patient was in the placebo group, Dr. Nicholls noted.
“Blood pressure is an important adverse event to look at in the CETP class given the challenges seen with the first CETP evaluated – torcetrapib,” Dr. Nicholls said. “But in the three clinical trials with obicetrapib conducted to date, reassuringly, we see no increase in either systolic or diastolic blood pressure with either the 5-mg or 10-mg dose.”
He concluded that obicetrapib “could be a valuable addition to high-risk patients with atherosclerotic cardiovascular disease who do not achieve their target LDL level despite use of high-intensity statin therapy.”
Differences from other CETP inhibitors
Asked how obicetrapib differs from other agents in the CETP inhibitor class, Dr. Nicholls replied that obicetrapib is much more potent, as shown by the large lipid changes seen with very small quantities of this drug, 5 mg or 10 mg, whereas prior CETP inhibitors showed smaller changes with much higher doses.
“We are giving very small amounts of obicetrapib and seeing very robust effects on both atherogenic and lipid parameters,” he said.
“The other major point with this class of agent is that the first drug, torcetrapib, had toxicity, which resulted in increased cardiovascular events. But it has now been established that torcetrapib had a number of off-target effects that have not been seen with subsequent agents in this class,” he said.
Studies so far show that obicetrapib does not have torcetrapib-like effects. “That is encouraging. This, and the impressive LDL lowering effects, certainly lay the foundation for larger studies moving forward,” he added.
“This has been an intriguing field to many of us involved from the start. We started with a very disappointing result with torcetrapib. Then a couple of studies looked to be clinically futile, but we were encouraged by the REVEAL study which suggested that there might be benefit,” Dr. Nicholls said.
“If we combined the REVEAL results with the genetic data, it has actually flipped the whole CETP story upside down. We started thinking that inhibiting CETP was all about raising HDL, but it turns out that it is about LDL lowering,” he said. “And that is not only important in terms of the lipid effects but also the trials and the way they are designed.
“I think you’ll find that the future trials in this class and with this agent will have LDL very much in mind and that will very much influence the study design,” he said, adding that a larger cardiovascular outcome trial is now being planned.
“The regulatory perspective is that LDL is a pretty trusted surrogate ... but I think an outcomes trial will be important to reinforce and reassure on safety and outline cost-effectiveness, which will help us understand where the sweet spot for using this agent in the clinic will be,” Dr. Nicholls noted.
Dr. Kastelein explained that it has taken some time to realize that CETP inhibitors may be valuable for reducing LDL.
“The first agent, torcetrapib, had an off-target toxicity that led to increased blood pressure but a specific part of the torcetrapib molecule was subsequently identified that was responsible for that, and subsequent agents in the CETP inhibitor class did not have such adverse effects,” he said.
“The next agent, dalcetrapib (Roche), raised HDL but didn’t move LDL, and an outcomes trial with evacetrapib (Lilly) was stopped after 2 years because of futility, but we now believe that lipid lowering trials need longer term follow-up – up to 5 years – to see a benefit,” he noted.
Dr. Kastelein reports that anacetrapib (Merck) has been the most powerful CETP inhibitor until now, giving an LDL reduction of about 20%, which was associated with a 10% reduction in cardiovascular events in first 4 years of follow-up.
“Oxford academic researchers decided to continue follow-up in this trial without Merck and showed a 20% reduction in cardiovascular events by 6 years. This has been the strongest rationale for our investors,” Dr. Kastelein said.
He pointed out that obicetrapib is much more potent than anacetrapib. “Obicetrapib reduces LDL by 50% at just a 10-mg dose, whereas anacetrapib was used at a dose of 100 mg to give a 17%-20% LDL reduction.”
Could HDL increase be beneficial after all?
Although increasing HDL is currently not thought to bring about a direct reduction in cardiovascular events, there is new evidence emerging that increasing HDL may confer some benefit in protecting against the development of type 2 diabetes, Dr. Kastelein noted.
“We know that statins can increase risk of developing type 2 diabetes, and post hoc analyses of previous trials with CETP inhibitors suggest that these drugs have the opposite effect,” he said. “We will investigate this protectively in our phase 3 outcomes trial. If this is a true effect, it should eventually translate into a reduction in cardiovascular outcomes, but this could take a longer time to see than the benefits of lowering LDL.”
Commenting on the current data, Steven Nissen, MD, of Cleveland Clinic, said: “The results are truly impressive – a nearly 50% LDL reduction on a background of statins with a once-daily oral agent. While PCSK9 inhibitors can achieve similar results, they are injectable and costly.
“Since anacetrapib, a much weaker CETP inhibitor, was successful at reducing major adverse cardiac events, the likelihood that obicetrapib would reduce MACE even more substantially is very high,” he added.
Dr. Nissen said he has been aware of this drug for some time and has advised the company about development options and regulatory strategy. “I have encouraged this company to develop this very promising drug,” he said.
The current study was funded by New Amsterdam Pharma. Dr. Nicholls reports grants from AstraZeneca, Amgen, Anthera, Eli Lilly, Esperion, Novartis, Cerenis, The Medicines Company, Resverlogix, Infraredx, Roche, Sanofi-Regeneron and LipoScience, and honoraria from New Amsterdam Pharma, AstraZeneca, Akcea, Eli Lilly, Anthera, Omthera, Merck, Takeda, Resverlogix, Sanofi-Regeneron, CSL Behring, Esperion, and Boehringer Ingelheim. Dr. Kastelein is chief scientific officer of New Amsterdam Pharma.

“Despite the use of high-intensity statins, two-thirds of patients do not reach their target LDL level, so we have a need for new therapies that lower LDL and can be used in combination with high-intensity statins,” he explained.
He noted that earlier studies with obicetrapib showed a 45% lowering of LDL with monotherapy.
Dr. Nicholls reported that recent evidence has emerged that increases interest in inhibiting CETP to be potentially cardioprotective.
To begin, genetic studies have shown that genetic polymorphisms associated with lower levels of CETP appear to be cardioprotective, and this is associated with lower levels of LDL rather than higher levels of HDL.
Furthermore, the REVEAL cardiovascular outcomes trial with anacetrapib (also a CETP inhibitor) in 2017 showed a significant 9% reduction in major adverse cardiac events (MACE) after 4 years of follow-up. “This was exactly predicted by the 11 mg/dL drop in absolute LDL cholesterol level. It was not predicted or associated with the increase in HDL level observed with that agent,” Dr. Nicholls said.
The objective of the current ROSE study was to evaluate the lipid-lowering ability, safety, and tolerability of obicetrapib in patients on high-intensity statins.
The study included 120 patients who had been treated on a stable dose of high-intensity statins (atorvastatin at a dose of at least 40 mg daily or rosuvastatin at a dose of 20 mg daily) for at least 8 weeks. All patients were required to have a fasting LDL of at least 70 mg/dL and the median baseline LDL was 90 mg/dL. They were randomly assigned to obicetrapib (5 mg or 10 mg daily) or placebo.
The primary endpoint was the difference between groups in percentage change in LDL from baseline to week 8, with LDL levels measured by two different techniques.
Results showed a “robust” 51% reduction in LDL with the 10-mg dose of obicetrapib, and a 42% reduction with the 5-mg dose, Dr. Nicholls reported.
These effects were comparable regardless of baseline LDL and were similar with both methods of LDL measurement.
Almost all patients demonstrated some degree of LDL cholesterol lowering, with only three patients on the 5-mg dose and one patient on the 10-mg dose not showing any reduction in LDL.
Other results showed a dose-dependent lowering of Apo B of up to 30%, and a reduction of non-HDL cholesterol of up to 44%.
“Predictably, there were also increases of HDL cholesterol,” Dr. Nicholls said. “At the 10-mg dose, we see a 165% increase in HDL levels. That is associated with a 48% increase in Apo A1 levels. This is very consistent with findings from the previous monotherapy study.”
There was a 56% reduction in Lp(a) levels, and a modest 11% reduction in triglycerides.
Both doses of obicetrapib were well tolerated, with no increase in the rate of adverse events. Only one patient discontinued the study drug because of an adverse event and that patient was in the placebo group, Dr. Nicholls noted.
“Blood pressure is an important adverse event to look at in the CETP class given the challenges seen with the first CETP evaluated – torcetrapib,” Dr. Nicholls said. “But in the three clinical trials with obicetrapib conducted to date, reassuringly, we see no increase in either systolic or diastolic blood pressure with either the 5-mg or 10-mg dose.”
He concluded that obicetrapib “could be a valuable addition to high-risk patients with atherosclerotic cardiovascular disease who do not achieve their target LDL level despite use of high-intensity statin therapy.”
Differences from other CETP inhibitors
Asked how obicetrapib differs from other agents in the CETP inhibitor class, Dr. Nicholls replied that obicetrapib is much more potent, as shown by the large lipid changes seen with very small quantities of this drug, 5 mg or 10 mg, whereas prior CETP inhibitors showed smaller changes with much higher doses.
“We are giving very small amounts of obicetrapib and seeing very robust effects on both atherogenic and lipid parameters,” he said.
“The other major point with this class of agent is that the first drug, torcetrapib, had toxicity, which resulted in increased cardiovascular events. But it has now been established that torcetrapib had a number of off-target effects that have not been seen with subsequent agents in this class,” he said.
Studies so far show that obicetrapib does not have torcetrapib-like effects. “That is encouraging. This, and the impressive LDL lowering effects, certainly lay the foundation for larger studies moving forward,” he added.
“This has been an intriguing field to many of us involved from the start. We started with a very disappointing result with torcetrapib. Then a couple of studies looked to be clinically futile, but we were encouraged by the REVEAL study which suggested that there might be benefit,” Dr. Nicholls said.
“If we combined the REVEAL results with the genetic data, it has actually flipped the whole CETP story upside down. We started thinking that inhibiting CETP was all about raising HDL, but it turns out that it is about LDL lowering,” he said. “And that is not only important in terms of the lipid effects but also the trials and the way they are designed.
“I think you’ll find that the future trials in this class and with this agent will have LDL very much in mind and that will very much influence the study design,” he said, adding that a larger cardiovascular outcome trial is now being planned.
“The regulatory perspective is that LDL is a pretty trusted surrogate ... but I think an outcomes trial will be important to reinforce and reassure on safety and outline cost-effectiveness, which will help us understand where the sweet spot for using this agent in the clinic will be,” Dr. Nicholls noted.
Dr. Kastelein explained that it has taken some time to realize that CETP inhibitors may be valuable for reducing LDL.
“The first agent, torcetrapib, had an off-target toxicity that led to increased blood pressure but a specific part of the torcetrapib molecule was subsequently identified that was responsible for that, and subsequent agents in the CETP inhibitor class did not have such adverse effects,” he said.
“The next agent, dalcetrapib (Roche), raised HDL but didn’t move LDL, and an outcomes trial with evacetrapib (Lilly) was stopped after 2 years because of futility, but we now believe that lipid lowering trials need longer term follow-up – up to 5 years – to see a benefit,” he noted.
Dr. Kastelein reports that anacetrapib (Merck) has been the most powerful CETP inhibitor until now, giving an LDL reduction of about 20%, which was associated with a 10% reduction in cardiovascular events in first 4 years of follow-up.
“Oxford academic researchers decided to continue follow-up in this trial without Merck and showed a 20% reduction in cardiovascular events by 6 years. This has been the strongest rationale for our investors,” Dr. Kastelein said.
He pointed out that obicetrapib is much more potent than anacetrapib. “Obicetrapib reduces LDL by 50% at just a 10-mg dose, whereas anacetrapib was used at a dose of 100 mg to give a 17%-20% LDL reduction.”
Could HDL increase be beneficial after all?
Although increasing HDL is currently not thought to bring about a direct reduction in cardiovascular events, there is new evidence emerging that increasing HDL may confer some benefit in protecting against the development of type 2 diabetes, Dr. Kastelein noted.
“We know that statins can increase risk of developing type 2 diabetes, and post hoc analyses of previous trials with CETP inhibitors suggest that these drugs have the opposite effect,” he said. “We will investigate this protectively in our phase 3 outcomes trial. If this is a true effect, it should eventually translate into a reduction in cardiovascular outcomes, but this could take a longer time to see than the benefits of lowering LDL.”
Commenting on the current data, Steven Nissen, MD, of Cleveland Clinic, said: “The results are truly impressive – a nearly 50% LDL reduction on a background of statins with a once-daily oral agent. While PCSK9 inhibitors can achieve similar results, they are injectable and costly.
“Since anacetrapib, a much weaker CETP inhibitor, was successful at reducing major adverse cardiac events, the likelihood that obicetrapib would reduce MACE even more substantially is very high,” he added.
Dr. Nissen said he has been aware of this drug for some time and has advised the company about development options and regulatory strategy. “I have encouraged this company to develop this very promising drug,” he said.
The current study was funded by New Amsterdam Pharma. Dr. Nicholls reports grants from AstraZeneca, Amgen, Anthera, Eli Lilly, Esperion, Novartis, Cerenis, The Medicines Company, Resverlogix, Infraredx, Roche, Sanofi-Regeneron and LipoScience, and honoraria from New Amsterdam Pharma, AstraZeneca, Akcea, Eli Lilly, Anthera, Omthera, Merck, Takeda, Resverlogix, Sanofi-Regeneron, CSL Behring, Esperion, and Boehringer Ingelheim.

Make cholesterol control a greater priority in diabetes
, a new population-based study in Finland suggests.
In the study, recently published online in Scientific Reports , the authors showed that LDL-C control and statin prescriptions remain suboptimal in this patient population in clinical practice.
They identified four 5-year trajectories of LDL-C along with concurrent levels of statin treatment. The percentages of patients in each group were:
- Moderately stable LDL-C: 2.3 mmol/L (90 mg/dL): 86%
- High stable LDL-C: 3.9 mmol/L (152 mg/dL): 7.7%
- Decreasing LDL-C: 3.8%
- Increasing LDL-C: 2.5%
“The second-largest group consisted of predominantly untreated patients (7.7%) with alarmingly ‘high stable’ LDL-C levels around 3.9 mmol/L,” the researchers noted.
And among patients with “increasing” LDL-C cholesterol, statin treatment “declined drastically.”
Moreover, 42% of patients had no statins prescribed at the end of follow-up.
These findings show that “efforts to control LDL-C should be increased – especially in patients with continuously elevated levels – by initiating and intensifying statin treatment earlier and reinitiating the treatment after discontinuation, if possible,” lead author Laura Inglin, MPH, told this news organization.
Discuss risks vs. benefits of statins with patients
Patients may not understand the benefits versus potential side effects of statins, said Ms. Inglin, of the Institute of Public Health and Clinical Nutrition, University of Eastern Finland, Kuopio.
To improve management of cholesterol levels, she said, “clinician-patient discussions are crucial, addressing risk/benefits and treatment goals, and offering reputable sources” of information about statins.
When patients discontinue statin treatment, Ms. Inglin continued, “physicians should try to reinitiate another statin or to lower the dose if possible, following guidelines on how to do that,” as other research has reported that more than 70% of patients who stopped a statin because of side effects tolerated it when it was restarted.
The study also identified gender differences, she continued. Compared with men, women had significantly higher average LDL-C levels, but were less likely to be prescribed a statin or were prescribed a lower-dose statin, and they were more likely to discontinue statin therapy.
Four LDL-C trajectories with statin treatment differences
Suboptimal lipid profiles, especially elevated LDL-C, are strongly associated with atherosclerotic CVD in individuals with type 2 diabetes, Ms. Inglin and colleagues write.
“To prevent or at least delay complications, regular follow-up visits and good control of A1c, LDL-C, blood pressure, and other CVD risk factors are vital in diabetes management,” they continued. “Guidelines have consistently identified statins as the principal lipid-lowering therapy, recommended particularly at moderate- to high-intensity.”
The researchers aimed to identify LDL-C level trajectories and concomitant statin treatment in patients with type 2 diabetes.
They identified 8,592 patients – 4,622 men (54%) and 3,970 women (46%) – with type 2 diabetes seen by primary care physicians or specialists in North Karelia, Eastern Finland, during 2011-2017.
As with other international guidelines, the Finnish Current Care Guideline recommended assessing LDL-C levels every 1-3 years in patients with type 2 diabetes, with LDL-C treatment targets of < 2.5 mmol/L (< 100 mg/dL) for those at high CVD risk due to diabetes, and targets of < 1.8 mmol/L (< 70 mg/dL) or a 50% reduction from baseline in those at very high CVD risk due to additional risk factors.
At baseline, on average, men in the current study were aged 66 years and had had diabetes for 8 years; 60% were receiving a statin and 56% had an LDL-C < 2.5 mmol/L.
Women were, on average, age 69 years and had had diabetes for 8 years; 56% were receiving a statin and 51% had an LDL-C < 2.5 mmol/L.
The researchers identified the four distinct LDL-C trajectories, each with differences in statin treatment.
In the “moderate-stable” LDL-C group, 67% of men and 64% of women were receiving a statin, and the rates of high-intensity statin increased in both men and women.
In the “high-stable” LDL-C group, rates of statin use decreased from 42% to 27% among men and from 34% to 23% among women.
In the “decreasing” LDL-C group, the proportion of patients who received a statin increased; the percentage of patients who received a high-intensity statin also increased among men (6.2% to 29%) and women (7.7% to 14%).
In the “increasing” LDL-C group, the percentage of patients receiving a statin decreased from more than 64% to less than 43%.
“Physicians should increase efforts to achieve the LDL-C treatment targets – especially in the patient group with constantly elevated LDL-C levels – by paying attention to earlier initiation of statin treatment, intensification of treatments when necessary, and reinitiating if possible,” the researchers reiterated.
“The results of our study may support physicians to identify patients who need to be monitored more closely beyond a single time point measurement,” they concluded.
The study was partly funded by the Strategic Research Council of the Academy of Finland (project IMPRO), the Finnish Diabetes Association, and the Research Committee of the Kuopio University Hospital Catchment Area for the State Research Funding (project QCARE). The authors have reported no relevant financial relationships.

AHA statement on impact of major life events on physical activity
Physical activity levels may decline during major life events, and it’s important for health care professionals to encourage patients to maintain regular physical activity during times of significant changes in their lives, the American Heart Association says in a new scientific statement.
With this statement, “We hope health care providers, public health workers, and individuals understand that a major life change can lead to decreases in physical activity or increases in sedentary behavior,” writing group chair Abbi D. Lane-Cordova, PhD, said in an interview.
The statement includes “tips for screening for physical activity and talking to people about their activity during these big life events and resources that can be used by health care providers to help people achieve healthy levels of physical activity,” said Dr. Lane-Cordova, assistant professor in exercise science, Arnold School of Public Health, University of South Carolina, Columbia.
The statement was published online Dec. 1 in the journal Circulation.
The AHA Committee on Physical Activity, part of the organization’s Council on Lifestyle and Cardiometabolic Health, began discussing this topic back in 2019, Dr. Lane-Cordova explained.
“We spoke as a group about how much activity levels can change when something big happens in life, like becoming a parent or retiring. The change in activity behavior (physical activity or sedentary behavior) is important because these activity behaviors can influence heart health,” she said.
The group started work on the scientific statement in early 2020 – “and then the pandemic hit, and it seemed more important than ever to create awareness and a resource for people to help improve, or at least maintain, favorable activity behaviors when there’s a profound change or event in life,” Dr. Lane-Cordova said.
Some more vulnerable than others
The writing group examined data on 17 different life events or transitions and found evidence that physical activity levels may decline during nine events: beginning a new school (elementary, middle, high school, or college); a first job or career change; a marriage or civil union; pregnancy; parenting; retirement; or moving into a long-term care facility.
The authors also identified individuals who may be particularly susceptible to lower levels of physical activity in general and during important life events. They include those with lower levels of education; those who live alone; those who lack access to a safe outdoor space; Black Americans; some members of the LGBTQ+ community; and women who are pregnant and new parents.
They offer practical strategies for health care professionals to support routine physical activity levels during major life events and transitions. These include asking simple questions about how life transitions may be changing physical activity patterns and encouraging the use of wearable step trackers to monitor levels and changes.
“It’s important to maintain or improve physical activity when major life events happen, which is often a time when exercise is most needed,” Dr. Lane-Cordova said in a news release.
“Clinicians should express compassion as they ask about life transitions and initiate conversations about physical activity during life events and transitions,” the writing group advises.
The group also says its important “to look beyond the health care setting and engage organizations, communities, workplaces, faith-based communities, and assisted living facilities to promote physical activity.”
The statement provides a list of resources for individuals and health care professionals, many of which are free and online.
This research had no commercial funding. Members of the writing group have disclosed no relevant financial relationships.

They include those with lower levels of education; those who live alone; those who lack access to a safe outdoor space; Black Americans; some members of the LGBTQ+ community; and women who are pregnant and new parents.
They offer practical strategies for health care professionals to support routine physical activity levels during major life events and transitions. These include asking simple questions about how life transitions may be changing physical activity patterns and encouraging the use of wearable step trackers to monitor levels and changes.
“It’s important to maintain or improve physical activity when major life events happen, which is often a time when exercise is most needed,” Dr. Lane-Cordova said in a news release.
“Clinicians should express compassion as they ask about life transitions and initiate conversations about physical activity during life events and transitions,” the writing group advises.
The group also says its important “to look beyond the health care setting and engage organizations, communities, workplaces, faith-based communities, and assisted living facilities to promote physical activity.”
The statement provides a list of resources for individuals and health care professionals, many of which are free and online.
This research had no commercial funding. Members of the writing group have disclosed no relevant financial relationships.

Could an oral PCSK9 inhibitor be on the horizon?
The investigational PCSK9 inhibitor that Merck showcased recently would be more than a “me-too” drug if it ultimately wins approval, despite competition from several approved agents that slash elevated cholesterol levels by targeting the same protein.
In fact, it would be something of a breakthrough. The new agent under study – now called MK-0616 – comes in pill form, in contrast to the three currently available PCSK9-lowering drugs that must be given in injections separated by weeks to months.
The drug faces an uncertain road to regulatory review and any approval, but MK-0616 at least seems to be starting out in the right direction.
In two phase 1 studies with a total of 100 participants, plasma PCSK9 levels plunged more than 90% after a single dose of the drug; and low-density-lipoprotein cholesterol (LDL-C) levels dropped about 65% when MK-0616 was given daily for 2 weeks on a background of statin therapy.
Moreover, “MK-0616 was generally well tolerated at up to and including single doses of 300 milligrams,” the maximum tested in the studies, Douglas G. Johns, PhD, reported at the virtual American Heart Association scientific sessions.
The collective results from the oral agent’s earliest human experience are “definitely encouraging” and support MK-0616 as a potential LDL-lowering agent that would be more convenient and arguably more accessible to patients compared to current injectable PCSK9 inhibitors, proposed Dr. Johns, clinical director of translational medicine for Merck in Kenilworth, N.J.
Available PCSK9-targeting agents include alirocumab (Praluent, Sanofi/Regeneron), Food and Drug Administration–approved in July 2015, and evolocumab (Repatha, Amgen), approved by the agency the following month. Both are monoclonal antibodies with neutralizing specificity for the PCSK9 protein; whereas the third such agent, inclisiran (Leqvio, Novartis) is a small-molecule interfering-RNA that suppresses PCSK9 synthesis. Inclisiran is approved in the European Union but its case to the FDA was turned down in 2020.
Dr. Johns said MK-0616 is a cyclic peptide that is “about one-hundredth the size of a monoclonal antibody, but we’re able to achieve monoclonal antibody-like potency and selectivity with this much smaller footprint.”
Added to statin therapy, the current PCSK9-targeting agents reduce LDL-C by an additional one-half or more, and the two antibody-based agents “also decrease atherosclerotic cardiovascular events. They are, however, expensive and not always available, requiring insurance or other approval,” observed Anne C. Goldberg, MD, as invited discussant after Dr. Johns’ presentation.
“They require every 2- to 4-week injections. They’re generally reserved for secondary prevention, and sometimes primary prevention as in familial hypercholesterolemia,” said Dr. Goldberg, of Washington University, St. Louis. Inclisiran, she noted, requires injections every 6 months and has yet to show its mettle in cardiovascular outcomes trials.
“Certainly, an oral form would be easier to use,” she said. “This would be particularly helpful in patients averse to injections,” especially, perhaps, in children. “Children with familial hypercholesterolemia could benefit with greater cholesterol lowering and might be better off with a pill than an injection.” That would be good reason to emphasize the enrollment of children in the drug’s upcoming clinical trials, Dr. Goldberg said.
But cost could potentially become restrictive for MK-0616 as well, should it ever be approved. “If it’s priced too high, then are you really going to see the increased use?” she posed. “Certainly, there’s a high bar for therapies that are add-on to statins in terms of cost effectiveness.”
In the first of the two trials, 60 predominantly White male participants aged 50 or younger were randomly assigned to receive a single dose of MK-0616, at different levels ranging from 10 mg to 300 mg, or placebo. They subsequently crossed over to a different group for a second round of dosing. Both times, three participants took the drug for every one who received placebo.
Participants who took the active drug, regardless of dosage, showed greater than 90% reductions in circulating PCSK9 levels compared to baseline. Six participants discontinued the study before its completion.
In the second trial, 40 White adults aged 65 or younger (mean, 58), including 13 women, with LDL-C of 60 mg/dL to 160 mg/dL (mean, 87 mg/dL) on statin therapy for at least 3 months were randomly assigned 3-to-1 to add-on MK-0616, either 10 mg or 20 mg daily, or placebo for 14 days.
LDL-C levels fell an average of about 65% over the 2 weeks among those taking the active drug; they declined less than 5% for those who took placebo.
There were no deaths or serious adverse events in either trial, Dr. Johns reported. On the other hand, pharmacokinetics studies showed that exposure to the drug fell by “about 50%-60%” when dosing was preceded by food intake within the previous 30 minutes. “However, if a meal is consumed 30 minutes after the dose, this food effect is much, much less prominent, almost negligible.”
These preliminary results show the drug is “orally bioavailable and exerts a clinically meaningful effect,” Dr. Johns said. “However, there’s definitely more to be done. And we are planning the next phase of clinical development, a phase 2 trial, sometime next year.”
The research was funded by Merck. Dr. Johns disclosed employment with and equity ownership in Merck, as did all the study’s coauthors. Dr. Goldberg disclosed holding research contracts through her institution with Regeneron/Sanofi-Aventis, Amarin, Amgen, Pfizer, IONIS/Akcea, Regeneron, Novartis, Arrowroot Pharmaceuticals, and the FH Foundation; and consulting for Novartis, Akcea, Regeneron, and Esperion.
