Metabolic Dysfunction–Associated Steatotic Liver Disease Plus HIV Ups Risk for CVD but Not Liver Disease
TOPLINE:
Metabolic dysfunction-associated steatotic liver disease (MASLD) co-occurring with HIV infection does not appear to increase the risk for cirrhosis or hepatocellular carcinoma (HCC) compared with MASLD alone. However, the incidence of major adverse cardiovascular events (MACE) is significantly increased among patients with MASLD and HIV, a large study suggested.
METHODOLOGY:
- MASLD is highly prevalent in people living with HIV, but the impact of HIV on liver and cardiovascular disease (CVD) outcomes in people with MASLD remains unclear.
- To investigate, researchers created a propensity score-matched cohort of veterans with noncirrhotic MASLD, with and without HIV (920 patients in each group).
- They evaluated the incidence of cirrhosis, HCC, and MACE, as well as overall survival, among the two groups. They also assessed these outcomes in MASLD patients with HIV on the basis of whether they were on antiretroviral therapy (ART).
TAKEAWAY:
- During a median follow-up of 10.4 years in the MASLD with HIV group and 11.8 years in the MASLD-only group, the overall incidence of cirrhosis and HCC was similar in MASLD with vs without HIV (cirrhosis: 0.97 vs 1.06 per 100 person-years, P = .54; HCC: 0.26 vs 0.17 per 100,000 person-years, P = .23), regardless of ART use.
- In contrast, the incidence of MACE was significantly higher in MASLD with vs without HIV (5.18 vs 4.48 per 100 person-years, P = .03). The incidence also was higher in patients with MASLD and HIV who were not on ART compared with those on ART (5.83 vs 4.7 per 100 person-years, P = .07).
- Compared with MASLD without HIV, the overall 5-year survival was significantly lower in MASLD with HIV (91.3% vs 85.7%). In MASLD with HIV, receipt of ART was associated with a significantly higher 5-year survival than no ART (87.4% vs 81.6%).
IN PRACTICE:
“Ensuring timely and appropriate initiation of HIV treatment is critical in patients with MASLD who have concurrent HIV infection, as well as optimizing metabolic comorbidities that may also contribute to increased risks of CVD and increased mortality,” the authors wrote.
SOURCE:
The study, led by Robert J. Wong, MD, Division of Gastroenterology and Hepatology, Stanford University School of Medicine, Palo Alto, California, was published online in the American Journal of Gastroenterology.
LIMITATIONS:
The study cohort consisted predominantly of older men, which may limit generalizability to women and younger populations. Metabolic comorbidities are more common in veterans compared with the general population, potentially affecting the generalizability of the CVD risk findings.
DISCLOSURES:
The study was supported by an investigator-initiated research grant from Theratechnologies. Wong has received funding for his institution from Gilead Sciences, Exact Sciences, and Durect Corporation and has served as a consultant for Gilead Sciences.

Novel PCSK9 Inhibitor Reduced LDL by 50%
Lerodalcibep, a novel, third-generation proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor, reduced low-density lipoprotein cholesterol (LDL-C) by more than 50% after 1 year in patients with or at a high risk for cardiovascular disease (CVD), new phase 3 results showed.
Newer, more stringent LDL targets in 90% of patients receiving lerodalcibep vs only 16% of those on placebo, despite concurrent treatment with a statin or statin plus ezetimibe.
“This hopefully gives doctors a more practical PCSK9 antagonist that’s small volume, can be administered monthly, and is an alternative to the every 2 week injection of monoclonal antibodies and probably more effective in LDL cholesterol–lowering compared to the small interfering RNA” medicines, study author Eric Klug, MBBCh, MMed, associate professor, Division of Cardiology, University of the Witwatersrand, Johannesburg, South Africa, told this news organization.
The findings from the LIBerate-HR trial were presented at the American College of Cardiology (ACC) Scientific Session 2024.
Additional Therapy Needed
The first goal is to get at least a 50% reduction in LDL-C, said Dr. Klug. The ACC, the American Heart Association, and the European Society of Cardiology recommended LDL-C of no more than 55 mg/dL as a goal for patients with CVD or who are at a very high risk for myocardial infarction or stroke and no more than 70 mg/dL for high-risk patients.
Most patients don’t get to that combined goal with statins and ezetimibe and need additional therapy, “and it appears the earlier you give the therapy the better,” said Dr. Klug.
Lerodalcibep is given as a low-dose (1.2-mL) monthly injection and is more convenient than other LDL-C–lowering options, said Dr. Klug. “This is a small-volume molecule that can be delivered subcutaneously once a month and can be kept on the shelf so it doesn’t need to be kept in the fridge, and you can travel with it.”
LIBerate-HR included 922 patients with CVD or at a high or very high risk for myocardial infarction or stroke at 66 centers in 11 countries. Over half (52%) fell into the at-risk category.
The mean age of participants was 64.5 years, 77% were White, and, notably, about 45% were women. Some 84% were taking a statin, 16.6% ezetimibe, a quarter had diabetes, and 10% had the more severe inherited familial hypercholesterolemia (FH).
Patients were randomly assigned to receive monthly 300-mg (1.2-mL) subcutaneous injections of lerodalcibep (n = 615) or placebo (n = 307) for 52 weeks.
The mean LDL-C at baseline was 116.9 mg/dL in the placebo group and 116.3 mg/dL in the treatment group.
The co-primary efficacy endpoints were the percent change from baseline in LDL-C at week 52 and the mean of weeks 50 and 52 (average of the peak and trough dose).
Compared with placebo, lerodalcibep reduced LDL-C by 56.19% at week 52 (P < .0001) and by 62.69% at mean week 50/52 (P < .0001). The absolute decreases were 60.6 mg/dL at week 52 and 74.5 mg/dL for mean week 50/52.
Rule of Thumb
“There’s a sort of rule of thumb that for every 40 mg/dL that LDL-C is reduced, you reduce major adverse cardiovascular events (MACE) by 20%-23%,” said Dr. Klug. “So, by reducing LDL-C by 60 mg/dL at week 52, you’re reducing your risk of MACE maybe by 30% or 35%.”
All subgroups reaped the same benefit from the intervention, noted Dr. Klug. “Whether you were male or female, under age 65, over age 65, baseline BMI less than median or more than median, White, Black or other, baseline statin intensity, diabetic or not diabetic, diagnosis of FH or not, it made no difference.”
As for secondary outcomes, most patients attained the newer, more stringent guideline-recommended LDL targets.
The treatment also reduced non–high-density lipoprotein cholesterol by 47%, apolipoprotein B by 43%, and Lp(a) by 33%.
Lerodalcibep was well-tolerated, with the number of patients with at least one adverse event similar to placebo (71.6% vs 68.1%) as was the case for the number with at least one serious adverse event (12.4% vs 13.4%).
Injection site reactions were mild to moderate. There was no difference in discontinuation rates due to these reactions (4.2% for the treatment and 4.6% for placebo).
A larger and longer trial to begin later this year should determine if the amount of LDL-C–lowering seen with lerodalcibep translates to greater reductions in cardiovascular events.
The company plans to file an application for approval to the US Food and Drug Administration in the next 2-4 months, said Dr. Klug.
Still Work to Do
During a press briefing, Dave L, Dixon, PharmD, professor and chair, Virginia Commonwealth University School of Pharmacy, Richmond, and member of the ACC Prevention of Cardiovascular Disease Council, congratulated the investigators “on moving this product forward and demonstrating the LDL-lowering efficacy, as well as providing some additional safety and tolerability data.”
He added it’s “clear” from the baseline LDL characteristics that “we have a lot of work to do in terms of helping patients achieve their lipid goals.”
Dr. Dixon noted up to about 30% of patients have some form of statin intolerance. “So, we really have to utilize our non-statin therapies, and unfortunately, we’re not doing a great job of that.”
That the trial enrolled so many women is “fantastic,” said Dr. Dixon, adding the investigators also “did a great job” of enrolling underrepresented minorities.
Having a once-a-month self-injection option “is great” and “fills a nice niche” for patients, said Dr. Dixon.
The study was funded by LIB Therapeutics, which manufactures lerodalcibep. Dr. Klug had no conflicts relevant to this study (he received honoraria from Novartis, Amgen, and Sanofi-Aventis).

FROM ACC 2024
Early Olezarsen Results Show 50% Reduction in Triglycerides
ATLANTA — A novel antisense therapy called olezarsen reduced triglycerides (TGs) by approximately 50% with either of the two study doses relative to placebo and did so with a low relative risk for adverse events, new data from a phase 2b trial showed.
“The reduction in triglycerides was greater than that currently possible with any available therapy,” reported Brian A. Bergmark, MD, an interventional cardiologist at Brigham and Women’s Hospital, Boston.
The drug also produced meaningful improvements in multiple other lipid subfractions associated with increased cardiovascular (CV) risk, including ApoC-III, very low–density lipoprotein (VLDL) cholesterol, ApoB, and non-LDL cholesterol. High-density lipoprotein (HDL) cholesterol levels were significantly raised.
The results were presented on April 7 as a late breaker at the American College of Cardiology (ACC) Scientific Session 2024 and published online simultaneously in The New England Journal of Medicine.
No Major Subgroup Failed to Respond
The effect was seen across all the key subgroups evaluated, including women and patients with diabetes, obesity, and severe as well as moderate elevations in TGs at baseline, Dr. Bergmark reported.
Olezarsen is a N-acetylgalactosamine–conjugated antisense oligonucleotide targeting APOC3 RNA.
In this study, 154 patients at 24 sites in North America were randomized in a 1:1 ratio to 50 or 80 mg olezarsen. Those in each of these cohorts were then randomized in a 3:1 ratio to active therapy or placebo. All therapies were administered by subcutaneous injection once per month.
Patients were eligible for the trial if they had moderate hypertriglyceridemia, defined as a level of 150-499 mg/dL, and elevated CV risk or if they had severe hypertriglyceridemia (≥ 500 mg/dL) with or without other evidence of elevated CV risk. The primary endpoint was a change in TGs at 6 months. Complete follow-up was available in about 97% of patients regardless of treatment assignment.
With a slight numerical advantage for the higher dose, the TG reductions were 49.1% for the 50-mg dose and 53.1% for the 80-mg dose relative to no significant change in the placebo group (P < .001 for both olezarsen doses). The reductions in ApoC-III, an upstream driver of TG production and a CV risk factor, were 64.2% and 73.2% relative to placebo (both P < .001), respectively, Dr. Bergmark reported.
In those with moderate hypertriglyceridemia, normal TG levels, defined as < 150 mg/dL, were reached at 6 months in 85.7% and 93.3% in the 40-mg and 80-mg dose groups, respectively. Relative to these reductions, normalization was seen in only 11.8% of placebo patients (P < .001).
TG Lowering Might Not Be Best Endpoint
The primary endpoint in this trial was a change in TGs, but this target was questioned by an invited ACC discussant, Daniel Soffer, MD, who is both an adjunct professor assistant professor of medicine at Penn Medicine, Philadelphia, and current president of the National Lipid Association.
Dr. Soffer noted that highly elevated TGs are a major risk factor for acute pancreatitis, so this predicts a clinical benefit for this purpose, but he thought the other lipid subfractions are far more important for the goal of reducing atherosclerotic cardiovascular disease (ASCVD).
Indeed, he said categorically that it is not TGs that drive ASCVD risk and therefore not what is the real importance of these data. Rather, “it is the non-HDL cholesterol and ApoB lowering” that will drive the likely benefits from this therapy in CV disease.
In addition to the TG reductions, olezarsen did, in fact, produce significant reductions in many of the lipid subfractions associated with increased CV risk. While slightly more favorable in most cases with the higher dose of olezarsen, even the lower dose reduced Apo C-III from baseline by 64.2% (P < .001), VLDL by 46.2% (P < .001), remnant cholesterol by 46.6% (P < .001), ApoB by 18.2% (P < .001), and non-HDL cholesterol by 25.4% (P < .001). HDL cholesterol was increased by 39.6% (P < .001).
These favorable effects on TG and other lipid subfractions were achieved with a safety profile that was reassuring, Dr. Bergmark said. Serious adverse events leading to discontinuation occurred in 0%, 1.7%, and 1.8% of the placebo, lower-dose, and higher-dose arms, respectively. These rates did not differ significantly.
Increased Liver Enzymes Is Common
Liver enzymes were significantly elevated (P < .001) for both doses of olezarsen vs placebo, but liver enzymes > 3× the upper limit of normal did not reach significance on either dose of olezarsen relative to placebo. Low platelet counts and reductions in kidney function were observed in a minority of patients but were generally manageable, according to Dr. Bergmark. There was no impact on hemoglobin A1c levels.
Further evaluation of change in hepatic function is planned in the ongoing extension studies.

ATLANTA — A novel antisense therapy called olezarsen reduced triglycerides (TGs) by approximately 50% with either of the two study doses relative to placebo and did so with a low relative risk for adverse events, new data from a phase 2b trial showed.
“The reduction in triglycerides was greater than that currently possible with any available therapy,” reported Brian A. Bergmark, MD, an interventional cardiologist at Brigham and Women’s Hospital, Boston.
The drug also produced meaningful improvements in multiple other lipid subfractions associated with increased cardiovascular (CV) risk, including ApoC-III, very low–density lipoprotein (VLDL) cholesterol, ApoB, and non-LDL cholesterol. High-density lipoprotein (HDL) cholesterol levels were significantly raised.
The results were presented on April 7 as a late breaker at the American College of Cardiology (ACC) Scientific Session 2024 and published online simultaneously in The New England Journal of Medicine.
No Major Subgroup Failed to Respond
The effect was seen across all the key subgroups evaluated, including women and patients with diabetes, obesity, and severe as well as moderate elevations in TGs at baseline, Dr. Bergmark reported.
Olezarsen is a N-acetylgalactosamine–conjugated antisense oligonucleotide targeting APOC3 RNA.
In this study, 154 patients at 24 sites in North America were randomized in a 1:1 ratio to 50 or 80 mg olezarsen. Those in each of these cohorts were then randomized in a 3:1 ratio to active therapy or placebo. All therapies were administered by subcutaneous injection once per month.
Patients were eligible for the trial if they had moderate hypertriglyceridemia, defined as a level of 150-499 mg/dL, and elevated CV risk or if they had severe hypertriglyceridemia (≥ 500 mg/dL) with or without other evidence of elevated CV risk. The primary endpoint was a change in TGs at 6 months. Complete follow-up was available in about 97% of patients regardless of treatment assignment.
With a slight numerical advantage for the higher dose, the TG reductions were 49.1% for the 50-mg dose and 53.1% for the 80-mg dose relative to no significant change in the placebo group (P < .001 for both olezarsen doses). The reductions in ApoC-III, an upstream driver of TG production and a CV risk factor, were 64.2% and 73.2% relative to placebo (both P < .001), respectively, Dr. Bergmark reported.
In those with moderate hypertriglyceridemia, normal TG levels, defined as < 150 mg/dL, were reached at 6 months in 85.7% and 93.3% in the 40-mg and 80-mg dose groups, respectively. Relative to these reductions, normalization was seen in only 11.8% of placebo patients (P < .001).
TG Lowering Might Not Be Best Endpoint
The primary endpoint in this trial was a change in TGs, but this target was questioned by an invited ACC discussant, Daniel Soffer, MD, who is both an adjunct professor assistant professor of medicine at Penn Medicine, Philadelphia, and current president of the National Lipid Association.
Dr. Soffer noted that highly elevated TGs are a major risk factor for acute pancreatitis, so this predicts a clinical benefit for this purpose, but he thought the other lipid subfractions are far more important for the goal of reducing atherosclerotic cardiovascular disease (ASCVD).
Indeed, he said categorically that it is not TGs that drive ASCVD risk and therefore not what is the real importance of these data. Rather, “it is the non-HDL cholesterol and ApoB lowering” that will drive the likely benefits from this therapy in CV disease.
In addition to the TG reductions, olezarsen did, in fact, produce significant reductions in many of the lipid subfractions associated with increased CV risk. While slightly more favorable in most cases with the higher dose of olezarsen, even the lower dose reduced Apo C-III from baseline by 64.2% (P < .001), VLDL by 46.2% (P < .001), remnant cholesterol by 46.6% (P < .001), ApoB by 18.2% (P < .001), and non-HDL cholesterol by 25.4% (P < .001). HDL cholesterol was increased by 39.6% (P < .001).
These favorable effects on TG and other lipid subfractions were achieved with a safety profile that was reassuring, Dr. Bergmark said. Serious adverse events leading to discontinuation occurred in 0%, 1.7%, and 1.8% of the placebo, lower-dose, and higher-dose arms, respectively. These rates did not differ significantly.
Increased Liver Enzymes Is Common
Liver enzymes were significantly elevated (P < .001) for both doses of olezarsen vs placebo, but liver enzymes > 3× the upper limit of normal did not reach significance on either dose of olezarsen relative to placebo. Low platelet counts and reductions in kidney function were observed in a minority of patients but were generally manageable, according to Dr. Bergmark. There was no impact on hemoglobin A1c levels.
Further evaluation of change in hepatic function is planned in the ongoing extension studies.
Characterizing these results as “exciting,” Neha J. Pagidipati, MD, a member of the Duke Clinical Research Institute and an assistant professor at the Duke School of Medicine, Durham, North Carolina, said that identifying a drug effective for hypertriglyceridemia is likely to be a major advance.

Magnesium and Metabolic Syndrome: Any Connection?
TOPLINE:
Higher urinary magnesium loss, as indicated by an elevated magnesium depletion score (MDS), may be an independent risk factor for metabolic syndrome in US adults.
METHODOLOGY:
- Increasing evidence suggests that chronic hypomagnesemia may play a role in the pathogenesis of metabolic disorders, including overweight and obesity, insulin resistance, type 2 diabetes, hypertension, and dyslipidemia.
- Researchers examined the relationship between magnesium status and metabolic syndrome in 15,565 US adults (mean age, 47 years; half women) participating in the National Health and Nutrition Examination Survey (2003-2018), of whom 5438 had metabolic syndrome (mean age, 55 years).
- Magnesium deficiency was predicted by MDS, a four-factor score that aggregates diuretic use (one point), proton pump inhibitor (one point), kidney function (estimated glomerular filtration rate; one or two points), and heavy (one point).
- MDS was categorized into six levels (by scores 0-5), with a higher MDS indicating a more severe magnesium deficiency.
- Metabolic syndrome was defined according to the National Cholesterol Education Program’s Adult Treatment Panel III report.
TAKEAWAY:
- The proportion of patients with MDS ≥ 2 was higher in the group with vs without metabolic syndrome (P < .05).
- Even after adjusting for potential confounding factors, each 1-unit increase in the MDS increased the odds of metabolic syndrome by about 30% (adjusted odds ratio, 1.31; 95% CI, 1.17-1.45).
- A dose-response relationship was observed between MDS and metabolic syndrome, with MDS level 1 being associated with 1.28-fold higher odds of metabolic syndrome (95% CI, 1.06-1.55) than MDS level 0; further escalation in the odds was noted for MDS levels 2, 3, and 4.
- The association between metabolic syndrome and MDS remained consistent across all population subgroups defined by age, gender, race (except Mexican American), body mass index, drinking status, or smoking status.
IN PRACTICE:
“It is possible to prevent and reduce MetS [metabolic syndrome] by supplementing with magnesium supplements or encouraging higher magnesium intake diet because the diet is a factor that can be changed,” the authors wrote.
SOURCE:
The study was led by Xiaohao Wang, Department of Geriatrics, the First Affiliated Hospital, School of Medicine, Southern University of Science and Technology (Shenzhen People’s Hospital), Shenzhen, China. It was published online in the Journal of Clinical Endocrinology & Metabolism.
LIMITATIONS:
The study found no significant link between MDS level 5 and metabolic syndrome, likely due to the small sample size at this level. The study could not draw any causal relationship between metabolic syndrome and MDS owing to its cross-sectional nature. It also could not determine whether MDS was a better marker of magnesium deficiency than serum magnesium levels. MDS is a categorical, not continuous, variable.
DISCLOSURES:
This study was supported by grants from the National Natural Science Foundation of China and the Natural Science Foundation of Shenzhen City, China. The authors declared no conflicts of interest.

Statins Tied to Lower Mortality, Even With Comorbid Dementia
Use of statin drugs was associated with improved mortality in older nursing home residents, regardless of dementia status, a new study showed.
The study is among the first to explore whether statin use in older nursing home residents offers a mortality benefit, especially among individuals with dementia, a group largely excluded from earlier statin trials.
Investigators’ analysis of 4 years of data on nearly 300,000 nursing home residents revealed that statin use was associated with a 40% lower risk for all-cause mortality than statin nonuse in those without dementia and a 20% lower risk in those with dementia.
“These findings may provide evidence that supports the continued use of statins in older nursing home patients with multiple medical conditions,” wrote lead author Julie Lorraine O’Sullivan, PhD, of the Charité–Universitätsmedizin Berlin, Freie Universität Berlin, German Center for Mental Health, Berlin, and colleagues.
The study was published online on February 27 in Neurology.
Understudied Population
Statins are the first-line treatment for preventing atherosclerotic cardiovascular disease (ASCVD), but they are also known to carry risks to patients who are frail or care-dependent. Many prior clinical trials excluded older participants with multiple comorbidities, especially those with dementia. So, evidence regarding the drugs’ efficacy in this population was lacking.
Investigators retrospectively examined 5 years of claims data from a German health and long-term care insurance provider on 282,693 nursing home residents (mean age, 83 years) who had used statins consecutively for ≥ 6 months.
Researchers used propensity score matching in 96,162 individuals to adjust for potential imbalances in the distribution of covariates (eg, age, sex, atrial fibrillation, ASCVD, and other conditions, as well as medications) and to reduce bias. Cox regression models were similarly adjusted for these factors, as well as care level. Residents were followed for an average of 2 years.
There were 54,269 recorded deaths during the study period, with most patients requiring a high level of care and 65% with dementia.
Statin use was associated with lower all-cause mortality in residents with dementia (hazard ratio [HR], 0.80, P < .001) and those without dementia (HR, 0.73; P < .001) compared with nonusers. The benefits remained consistent even after excluding participants with a history of ASCVD and across subgroups stratified by age sex, care level, and dementia type.
Limitations included the potential for unknown confounders and a lack of information about previous statin use, smoking and sedentary behavior, and the cause of mortality.
“Although our findings suggest the benefits of statins ... it is vital to acknowledge the need for further research to understand the underlying mechanism and the need for replication of our results to understand the potential risks before making recommendations to clinicians and families regarding statin therapy,” investigators wrote.
‘First Step’
In an accompanying editorial, Ariela R. Orkaby, MD, MPH, assistant professor of medicine, Brigham and Women’s Hospital, Harvard Medical School, Boston, called the study a “first step” to a better understanding of statin use in an understudied population.
“These findings build on a limited body of observational evidence for statin use in high-risk older adults, which has generally demonstrated protective associations for statins and mortality, including those with dementia and frailty, although nursing home status has not been specifically explored,” Dr. Orkaby wrote.
Perhaps more important than gaining information about statins’ effect on mortality risk in older people with dementia may be a better understanding of how the drugs might improve quality of life by reducing the risk for stroke or other cardiovascular events.
“It may be time to reconsider the broad recommendations to avoid or deprescribe statins in nursing home residents and rather invest in high-quality evidence to guide the care of this vulnerable population. After all, a lack of evidence does not imply benefit or harm, rather a need for more data,” Dr. Orkaby added.
The research was funded by Stiftung Charité; Dr. O’Sullivan and coauthors reported no relevant financial relationships. Dr. Orkaby received funding from a VA CSR&D CDA-2 award.

After all, a lack of evidence does not imply benefit or harm, rather a need for more data,” Dr. Orkaby added.
The research was funded by Stiftung Charité; Dr. O’Sullivan and coauthors reported no relevant financial relationships. Dr. Orkaby received funding from a VA CSR&D CDA-2 award.

Phase 2 Results: Zerlasiran siRNA Drug Lowers Lp(a) by 90%
Silence Therapeutics shared positive topline 36-week data from its ongoing phase 2 study of zerlasiran, a long-acting agent directed at lowering Lp(a) levels.
In a statement, the company said the study shows a highly significant reduction from baseline in Lp(a) levels with zerlasiran compared with placebo at 36 weeks, the primary endpoint.
Zerlasiran (formerly known as SLN360), is a short interfering RNA (siRNA) agent, or “ gene silencing” therapy. It binds to and temporarily blocks the action of the LPA gene which encodes for apolipoprotein(a), a dominant and a rate-limiting component in the hepatic synthesis of the Lp(a) particle.
A previous phase 1 study showed that single subcutaneous doses of the drug, ranging from 30 mg to 600 mg, produced a dose-dependent reduction in Lp(a) plasma levels at 45-60 days.
The current double-blind placebo-controlled phase 2 trial — known as ALPACAR-360 — enrolled 178 patients at high risk for atherosclerotic cardiovascular events who had elevated levels of Lp(a), ie, ≥ 125 nmol/L (median baseline Lp(a) was approximately 215 nmol/L). They were randomized to zerlasiran or placebo.
Zerlasiran was administered at 300 mg subcutaneously every 16 or 24 weeks or at 450 mg every 24 weeks.
The 60-week study is ongoing, and secondary endpoints, including change in Lp(a) from baseline to 48 weeks (end of treatment period) and 60 weeks (end of study) and potential effects on other lipids/lipoproteins, will be evaluated.
Silence says it plans to report topline 48-week data from the ALPACAR-360 study in the second quarter of this year.
Elevated levels of Lp(a) represent a genetic risk factor for cardiovascular disease, which is believed to affect approximately 20% of the population. Although there are currently no approved Lp(a)-lowering therapies, several drug candidates are in late-stage clinical testing.

Semaglutide Curbs MASLD Severity in People Living With HIV
Semaglutide improved metabolic dysfunction–associated steatotic liver disease (MASLD) among people living with HIV, and in some cases resolved it completely, according to results from the SLIM LIVER study presented by the AIDS Clinical Trials Group (ACTG) at this year’s Conference on Retroviruses and Opportunistic Infections (CROI) 2024 Annual Meeting in Denver.
Furthermore, although muscle volume decreased with weight loss, participants did not experience significant changes in muscle quality or physical function.
‘A First’
SLIM LIVER is the first study evaluating semaglutide as a treatment of MASLD among people living with HIV.
The phase 2b, single-arm pilot study enrolled adults living with HIV who were virally suppressed and had central adiposity, insulin resistance or prediabetes, and steatotic liver disease.
Participants self-injected semaglutide weekly at increasing doses until they reached a 1-mg dose at week 4. At 24 weeks, the study team assessed changes in participants’ intra-hepatic triglyceride content using magnetic resonance imaging-proton density fat fraction.
The primary analysis results from SLIM LIVER were reported in an oral presentation, “Semaglutide Reduces Metabolic-Associated Steatotic Liver Disease in People With HIV: The SLIM LIVER Study,” on March 5 by Jordan E. Lake, MD, MSc, of UTHealth Houston.
A subgroup analysis of the study was provided in a poster, “Effects of Semaglutide on Muscle Structure and Function in the SLIM LIVER Study,” presented on March 4 by Grace L. Ditzenberger, PT, DPT, of the University of Colorado Anschutz Medical Campus in Aurora.
In the primary analysis, the median age of the 49 participants was 52 years, 43% were women (cisgender and transgender), the mean body mass index was 35, 39% were Hispanic and 33% were Black/African American, and 82% were taking antiretroviral therapy that included an integrase inhibitor.
Liver fat was reduced by an average of 31%, with 29% of participants experiencing a complete resolution (5% or less liver fat) of MASLD. They also experienced weight loss, reduced fasting blood glucose, and reduced fasting triglycerides, consistent with effects observed in studies of semaglutide in people without HIV.
The sub-analysis of the 46 participants for whom muscle measurements were available showed that muscle volume (measured in the psoas) decreased but with no significant change in physical function.
Semaglutide was generally well tolerated, with an adverse event profile similar to that seen in individuals without HIV.
The most common adverse events were gastrointestinal (ie, nausea, diarrhea, vomiting, and abdominal pain). Two participants experienced more significant adverse events possibly related to semaglutide but were able to continue in the study.
All participants completed the full 24 weeks of therapy at the originally prescribed dose.
Potential Impact
“Even at the low dose of 1 mg every week, most participants lost significant weight, and weight loss was closely associated with improvements in MASLD,” Dr. Lake said. “Additional research will assess the secondary effects of semaglutide on systemic inflammation and metabolism and determine whether semaglutide may have unique risks or benefits for people living with HIV.”
“These findings have the potential to have a significant impact on the health and quality of life of people living with HIV,” added ACTG Chair Judith Currier, MD, MSc, University of California Los Angeles.
The SLIM LIVER study was sponsored by the US National Institute of Allergy and Infectious Diseases (NIAID), with additional funding from UTHealth Houston McGovern School of Medicine. ACTG is a clinical trials network focused on HIV and other infectious diseases, funded by NIAID and collaborating institutes of the US National Institutes of Health.
No conflicts of interest were reported.

Nurse-Led Strategy Reduces Cholesterol, BP in HIV
TOPLINE:
A multicomponent strategy of nurse-led communication, home blood pressure monitoring, evidence-based treatment algorithms, and electronic health record tools improved systolic blood pressure (SBP) and non–high-density lipoprotein (non-HDL) cholesterol levels in people living with HIV.
METHODOLOGY:
- Investigators assessed if EXTRA-CVD, a nurse-led multicomponent intervention for preventing cardiovascular diseases (CVD), could effectively improve SBP and non-HDL cholesterol levels in people living with HIV whose viral replication has been controlled effectively using antiretroviral therapy.
- They recruited 297 individuals (median age, 59 years; 20.9% women) from three academic HIV clinics in the United States with an HIV-1 viral load < 200 copies/mL who were diagnosed with both hypertension and hypercholesterolemia.
- Participants were randomly assigned to either the EXTRA-CVD intervention group or a control group comprising individuals who received general prevention education.
- SBP (the primary outcome) was calculated as the mean of two SBP measurements obtained 1 minute apart, and non-HDL cholesterol (the secondary outcome) was calculated as total cholesterol minus HDL cholesterol.
TAKEAWAY:
- Participants in the intervention vs control group reported having significantly lower SBP as early as 4 months after the nurse-led strategy (mean difference, −6.4 mm Hg; P = .002), with the improvements sustaining until 12 months (mean difference, −4.2 mm Hg; P = .04).
- At 12 months, participants in the intervention group showed a 16.9-mg/dL (P < .001) reduction in non-HDL cholesterol levels compared with those in the control group.
- The nurse-led strategy led to a greater reduction in SBP in women with HIV vs men living with HIV (5.9 mm Hg greater SBP difference at 12 months), with the difference being clinically meaningful but not statistically significant.
- This nurse-led strategy did not increase the risk for adverse events in people living with HIV.
IN PRACTICE:
“Although the EXTRA-CVD intervention was limited to BP and cholesterol, nurse-led case management might be beneficial for a range of other primary care conditions in HIV clinics. If HIV clinics choose to implement EXTRA-CVD, they might consider adding staff trained in other chronic comorbidities and/or health promotion activities,” the authors noted.
SOURCE:
This study was led by Christopher T. Longenecker, MD, University of Washington School of Medicine, Seattle, and published online on March 5, 2024, in JAMA Network Open.
LIMITATIONS:
Because this trial was conducted at well-resourced, major academic HIV clinics, the results may not be applicable to other populations, such as smaller community-based clinics or HIV care outside the United States. The sensitivity analyses performed in this study may not have fully accounted for the bias introduced by the differential attrition in the intervention group.
DISCLOSURES:
This study was supported by grants from the National Institutes of Health (NIH). The authors declared receiving grants and personal fees from or having other ties with the NIH and other sources.

Higher Dietary Niacin Tied to Lower Mortality Risk in MASLD
TOPLINE:
Higher dietary niacin intake is associated with a lower risk for all-cause mortality among people with metabolic dysfunction-associated steatotic liver disease (MASLD), but there is no connection between niacin consumption and cardiovascular disease (CVD) mortality, a recent study suggested.
METHODOLOGY:
- Researchers analyzed data from the National Health and Nutrition Examination Survey (2003-2018) for 4315 adults with MASLD (mean age, 52.5 years; 55%, men; 67%, non-Hispanic White).
- Dietary niacin intake levels were based on two 24-hour dietary recall interviews to report the types and quantities of foods that participants consumed in the 24 hours prior to the interviews.
- Participants were categorized by tertile of dietary niacin intake: Tertile 1 (n = 1440), < 18.4 mg; tertile 2 (n = 1441), 18.5-26.6 mg; and tertile 3 (n = 1434), > 26.7 mg.
TAKEAWAY:
- During a median follow-up of 8.8 years, 566 deaths occurred, of which 197 were attributed to CVD.
- Compared with participants with a niacin intake of 18.4 mg or lower (the lowest tertile), the multivariable-adjusted hazard ratios (HRs) for participants with a niacin intake of 26.7 mg or higher (the highest tertile) were 0.70 for all-cause mortality and 0.65 for CVD mortality.
- For the subgroup with diabetes compared with the reference group (the first tertile), the HR of all-cause mortality in the third tertile was 0.82.
- When the subgroup without diabetes was compared with the reference group, the HR of all-cause mortality in the third tertile was 0.58, suggesting a significant interaction between niacin and diabetes with the risk of all-cause mortality.
- An inverse association between dietary niacin intake and all-cause mortality was seen in sensitivity analyses, when excluding a participant who died within 2 years of follow-up.
IN PRACTICE:
“Higher dietary niacin intake was associated with a lower risk of all-cause mortality,” but not CVD, among individuals with MASLD, and “the dose-response association…needs to be further investigated to determine optimal intake level,” the authors wrote.
SOURCE:
The study, led by Jie Pan, MD, Sun Yat-sen University, Guangzhou, China, was published online in JAMA Network Open.
LIMITATIONS:
Physical activity data were missing and could not be adjusted for. The National Death Index used by the researchers has only “modest” ability to accurately classify CVD mortality, and the dietary data were subject to recall bias.
DISCLOSURES:
One author was supported by a grant from the National Nature Science Foundation of China. No other conflicts of interest were reported.

- For the subgroup with diabetes compared with the reference group (the first tertile), the HR of all-cause mortality in the third tertile was 0.82.
- When the subgroup without diabetes was compared with the reference group, the HR of all-cause mortality in the third tertile was 0.58, suggesting a significant interaction between niacin and diabetes with the risk of all-cause mortality.
- An inverse association between dietary niacin intake and all-cause mortality was seen in sensitivity analyses, when excluding a participant who died within 2 years of follow-up.
IN PRACTICE:
“Higher dietary niacin intake was associated with a lower risk of all-cause mortality,” but not CVD, among individuals with MASLD, and “the dose-response association…needs to be further investigated to determine optimal intake level,” the authors wrote.
SOURCE:
The study, led by Jie Pan, MD, Sun Yat-sen University, Guangzhou, China, was published online in JAMA Network Open.
LIMITATIONS:
Physical activity data were missing and could not be adjusted for. The National Death Index used by the researchers has only “modest” ability to accurately classify CVD mortality, and the dietary data were subject to recall bias.
DISCLOSURES:
One author was supported by a grant from the National Nature Science Foundation of China. No other conflicts of interest were reported.

Does worsening metabolic syndrome increase the risk of developing cancer?
The conditions that comprise metabolic syndrome (high blood pressure, high blood sugar, increased abdominal adiposity, and high cholesterol and triglycerides) have been associated with an increased risk of diseases, including heart disease, stroke, and type 2 diabetes, wrote Li Deng, PhD, of Capital Medical University, Beijing, China, and colleagues.
A systematic review and meta-analysis published in Diabetes Care in 2012 showed an association between the presence of metabolic syndrome and an increased risk of various cancers including liver, bladder, pancreatic, breast, and colorectal.
More recently, a 2019 study published in Diabetes showed evidence of increased risk for certain cancers (pancreatic, kidney, uterine, cervical) but no increased risk for cancer overall.
However, the reasons for this association between metabolic syndrome and cancer remain unclear, and the effect of the fluctuating nature of metabolic syndrome over time on long-term cancer risk has not been explored, the researchers wrote.
What Does New Study Add to Other Research on Metabolic Syndrome and Cancer Risk?
In the new study, published in Cancer on March 11 (doi: 10.1002/cncr.35235), 44,115 adults in China were separated into four trajectories based on metabolic syndrome scores for the period from 2006 to 2010. The scores were based on clinical evidence of metabolic syndrome, defined using the International Diabetes Federation criteria of central obesity and the presence of at least two other factors including increased triglycerides, decreased HDL cholesterol, high blood pressure (or treatment for previously diagnosed hypertension), and increased fasting plasma glucose (or previous diagnosis of type 2 diabetes).
The average age of the participants was 49 years. The four trajectories of metabolic syndrome were low-stable (10.56% of participants), moderate-low (40.84%), moderate-high (41.46%), and elevated-increasing (7.14%), based on trends from the individuals’ initial physical exams on entering the study.
Over a median follow-up period of 9.4 years (from 2010 to 2021), 2,271 cancer diagnoses were reported in the study population. Those with an elevated-increasing metabolic syndrome trajectory had 1.3 times the risk of any cancer compared with those in the low-stable group. Risk for breast cancer, endometrial cancer, kidney cancer, colorectal cancer, and liver cancer in the highest trajectory group were 2.1, 3.3, 4.5, 2.5, and 1.6 times higher, respectively, compared to the lowest group. The increased risk in the elevated-trajectory group for all cancer types persisted when the low-stable, moderate-low, and moderate-high trajectory pattern groups were combined.
The researchers also examined the impact of chronic inflammation and found that individuals with persistently high metabolic syndrome scores and concurrent chronic inflammation had the highest risks of breast, endometrial, colon, and liver cancer. However, individuals with persistently high metabolic syndrome scores and no concurrent chronic inflammation had the highest risk of kidney cancer.
What Are the Limitations of This Research?
The researchers of the current study acknowledged the lack of information on other causes of cancer, including dietary habits, hepatitis C infection, and Helicobacter pylori infection. Other limitations include the focus only on individuals from a single community of mainly middle-aged men in China that may not generalize to other populations.
Also, the metabolic syndrome trajectories did not change much over time, which may be related to the short 4-year study period.
What Is the Takeaway Message for Clinical Practice?
The results suggest that monitoring and managing metabolic syndrome could help reduce cancer risk, the researchers concluded.
“This research suggests that proactive and continuous management of metabolic syndrome may serve as an essential strategy in preventing cancer,” senior author Han-Ping Shi, MD, PhD, of Capital Medical University in Beijing, said in a press release accompanying the study.
More research is needed to assess the impact of these interventions on cancer risk, he noted. However, the data from the current study can guide future research that may lead to more targeted treatments and more effective preventive strategies, he said in a statement.
The study was supported by the National Key Research and Development Program of China. The researchers had no financial conflicts to disclose.
