NAFLD can regress with weight loss, activity
BOSTON – All phenotypes of nonalcoholic fatty liver disease (NAFLD) can progress or regress even without pharmacologic intervention, according to a prospective longitudinal study of 394 patients.
Weight loss and baseline NAFLD Activity Score predicted resolution of NAFLD, while weight gain and rising serum transaminases predicted progression to nonalcoholic steatohepatitis (NASH), Arun J. Sanyal, MD, said at the annual meeting of the American Association for the Study of Liver Diseases. Baseline and subsequent NAFLD Activity Score also was “a strong predictor of fibrosis progression or regression,” as was AST, portal inflammation, and baseline fibrosis stage, said Dr. Sanyal of Virginia Commonwealth University in Richmond, Va.
NAFLD comprises two main phenotypes, fatty liver and steatohepatitis. “The phenotype can change over time, and both phenotypes can be associated with fibrosis,” Dr. Sanyal noted. To better understand trends and clinical correlates for these phenotypes, he and his associates analyzed prospectively collected clinical and biopsy data from the NASH Clinical Research Network of the National Institutes of Diabetes and Digestive and Kidney Diseases. Each patient attended multiple clinic visits and underwent two liver biopsies at least 1 year and usually 4-5 years apart, which were interpreted by a masked central pathology review committee.
At baseline, 75 patients had fatty liver without steatohepatitis, of which only 13% resolved and 44% progressed to borderline or definite steatohepatitis. Similarly, among 74 patients with borderline steatohepatitis at baseline, only 22% regressed to fatty liver disease without steatohepatitis, while 43% progressed to definite steatohepatitis. The remaining 245 patients had definite steatohepatitis at baseline, of which 58% failed to regress at all, 20% regressed to borderline, 11% regressed to fatty liver disease without steatohepatitis, and 11% regressed to normal.
The investigators also performed a multivariable analysis of 197 patients with complete data. After the investigators controlled for serum insulin level, alkaline phosphatase level, NAS, and the presence of metabolic syndrome, each 10-U/L increase in ALT more than doubled the odds of progression from fatty liver without steatohepatitis to NASH (odds ratio, 2.2; 95% confidence interval, 1.1 to 4.1; P = .02). The association was even stronger for AST (OR, 3.5; 95% CI, 1.2 to 10.4; P = .03), and each 1-kg gain in body weight increased the odds of progression to NASH by 70% (OR, 1.7; 95% CI, 1.1 to 2.5; P = .01). In contrast, resolution of NAFLD was associated with weight loss (OR per 1 kg, 0.9; P less than .001) and lower baseline NAFLD Activity Score (OR, 0.7; P = .04).
About one in four patients had evidence of fibrosis at baseline, and 44% had at least stage 1 fibrosis at follow-up biopsy. Patients whose NAFLD progressed to a more severe phenotype were much more likely to have evidence of progressive fibrosis than were those whose NAFLD did not progress (OR, 7.2; 95% CI, 2.1 to 21.5; P less than .001), and there was no evidence that time between liver biopsies influenced this relationship. Among patients with definite NASH who had stage 0 fibrosis at baseline, 50% progressed to at least 1 fibrosis stage over the next 6.8 years, and 50% progressed to at least 2 stages over 9.6 years. Patients whose baseline NAFLD Activity Scores were between 1 and 4 were most likely to experience regression of fibrosis, while those with scores between 5 and 8 were more likely to have worsening fibrosis. Patients with severe baseline NAFLD Activity Score component scores for steatosis, lobular inflammation, and ballooning also were significantly more likely to have progressive fibrosis than were those with baseline NAFLD Activity Scores of 0 or 1. Furthermore, increasing NAFLD Activity Score over time predicted fibrosis progression.
Diabetes did not seem to affect fibrosis progression or regression, Dr. Sanyal noted. However, baseline portal inflammation predicted worsening fibrosis (P less than .01), as did baseline and subsequent elevations in AST (P less than .001), insulin (P = .03), and NAS (P less than 001), and baseline ballooning (P less than .01).
The investigators reported that the study had no sponsors. Dr. Sanyal disclosed ties to a wide number of drug companies.

What’s New in Rare Neuromuscular Disorders?
LAS VEGAS—At the American Academy of Neurology’s Fall 2016 Conference, Robert M. Pascuzzi, MD, presented several case videos to illustrate recent advances in caring for patients with rare neuromuscular disorders, including myasthenia gravis, Lambert-Eaton syndrome, Duchenne muscular dystrophy, and amyotrophic lateral sclerosis (ALS). Dr. Pascuzzi is Chair of the Department of Neurology at Indiana University School of Medicine in Indianapolis.
Myasthenia Gravis
The first case, a 55-year-old woman with a six-month history of double vision and swallowing trouble, also expressed the Cogan lid twitch, which is “pathognomonic for myasthenia gravis,” Dr. Pascuzzi said.
“It’s nice to have a test to confirm your clinical suspicions,” he said, noting that antibodies to the acetylcholine receptor (AChR) yield “almost perfect specificity” for myasthenia gravis. Other antibodies in use or under study to confirm this diagnosis include muscle-specific kinase (MuSK), low-density lipoprotein receptor-related protein 4 (LRP4), agrin, and cortactin.
The recently completed International Thymectomy Trial, which followed 126 patients for three years, found that those randomly assigned to transsternal thymectomy plus prednisone versus prednisone alone had significantly improved clinical outcomes, as measured on the Quantitative Myasthenia Gravis scale. Patients also required less prednisone, 44 mg versus 60 mg (alternate days), and fewer patients in the thymectomy group required azathioprine (17% versus 48%) or were hospitalized for exacerbations (9% versus 37%).
“Up until this study, nobody was completely sure this treatment worked,” Dr. Pascuzzi said.
Lambert-Eaton Syndrome
In the second case, a woman presented with a six-month history of falling down after her legs gave out on her. She also complained of dry mouth and, on examination, had proximal weakness and no muscle stretch reflexes.
Serology and EMG testing confirmed Lambert-Eaton myasthenic syndrome, a paraneoplastic syndrome. Half the patients with this syndrome have small cell carcinoma, Dr. Pascuzzi said, usually lung, due to smoking. In 64% of cases, the SOX1 antibody is positive.
Treatment approaches include treating the cancer; and 3,4 diaminopyridine, pyridostigmine, and immunotherapy.
Duchenne Muscular Dystrophy
A six-year-old boy with progressive clumsiness was found to have Duchenne muscular dystrophy, a diagnosis with “huge” genetic implications for his three younger brothers, Dr. Pascuzzi said. By age 20, patients are usually on ventilators.
Recently, the FDA granted accelerated approval to the first drug to treat Duchenne muscular dystrophy—Exondys 51 (eteplirsen). The drug “is specifically indicated for patients who have a confirmed mutation of the dystrophin gene amenable to exon 51 skipping, which affects about 13% of the population with Duchenne muscular dystrophy,” the FDA noted.
However, eteplirsen is not without controversy, Dr. Pascuzzi said. “There’s no documented clinical benefit. If you show there is a little more dystrophin being deposited and built in muscle, what does that mean? As of today, nobody knows. So that is an issue I think the FDA Advisory Panel and other people are worried about. And then, at $300,000 a year, it is not a financially insignificant impact.”
As the drug is used, further studies and data “will eventually show that it does or does not have clinical benefit,” Dr. Pascuzzi said. Patients must undergo testing for the mutation. Reported adverse events include balance issues and vomiting.
Amyotrophic Lateral Sclerosis
The third and fourth cases focused on a 53-year-old man with 12 months of progressive decline in speech and swallowing, and a woman with similar symptoms who also would laugh for no apparent reason. Both cases were displaying the pseudobulbar affect of ALS.
About 5% to 10% of all ALS cases are familial and, in 40% to 50%, the most common gene is C9orf72. Less common is the SOD1 gene (20%), with those carrying its A4V mutation generally dying within one year. Other mutations include TDP-43 (5%), and FUS (5%).
Dr. Pascuzzi cautioned that cognitive impairment among patients with ALS can be as high as 40% and cannot usually be detected on a bedside exam. Up to 15% of patients “get a frank, overt, clinically significant dementia, usually a frontotemporal syndrome.”
Treatment approaches include use of multidisciplinary clinics, ankle-foot orthosis, tools for activities of daily living, bilevel positive airway pressure, chin tuck, and power chairs; drugs include riluzole, dextromethorphan/quinidine for pseudobulbar affect, and drugs for spasticity.
He said it is important to address fear, depression, and anxiety in patients with ALS, and not to overlook the caregiver: “We are slowly but surely melting down our caregivers.”
A recent study in Lancet Neurology helped Dr. Pascuzzi and colleagues decide against diaphragm pacing for patients with respiratory insufficiency due to ALS, due to the potential for harm. “I would be cautious about pursuing this,” he said.
Despite the many failed controlled trials over the past 20 years, much investigational work is being done on ALS therapeutics, from injection of antisense molecules to tirasemtiv to stem cells, immune therapy, neuro-protection, and high fat/calorie diet, “so there is reason to be hopeful.”
Stem cell transplantation, in particular, is something he said his patients always ask him about. Two forms, “both important,” have undergone fairly extensive clinical investigation.
In the first, spinal cord-derived neural stem cells are transplanted into the spinal cord.
“The people that drive this work are convinced this is not stem cells that turn into motor neurons and replace lost or failing motor neurons, but instead these are stem cells that provide an environment that is more favorable for sick motor neurons,” Dr. Pascuzzi said. “They secrete nerve growth factors and transport proteins to improve the environment.”
The second approach, autologous stem cell treatment, is a “culture-based method for inducing mesenchymal stem cells to secrete neurotrophic factors,” he said, which has been “shown to be protective in several animal models of neurodegenerative diseases.”

Dr. Pascuzzi cautioned that cognitive impairment among patients with ALS can be as high as 40% and cannot usually be detected on a bedside exam. Up to 15% of patients “get a frank, overt, clinically significant dementia, usually a frontotemporal syndrome.”
Treatment approaches include use of multidisciplinary clinics, ankle-foot orthosis, tools for activities of daily living, bilevel positive airway pressure, chin tuck, and power chairs; drugs include riluzole, dextromethorphan/quinidine for pseudobulbar affect, and drugs for spasticity.
He said it is important to address fear, depression, and anxiety in patients with ALS, and not to overlook the caregiver: “We are slowly but surely melting down our caregivers.”
A recent study in Lancet Neurology helped Dr. Pascuzzi and colleagues decide against diaphragm pacing for patients with respiratory insufficiency due to ALS, due to the potential for harm. “I would be cautious about pursuing this,” he said.
Despite the many failed controlled trials over the past 20 years, much investigational work is being done on ALS therapeutics, from injection of antisense molecules to tirasemtiv to stem cells, immune therapy, neuro-protection, and high fat/calorie diet, “so there is reason to be hopeful.”
Stem cell transplantation, in particular, is something he said his patients always ask him about. Two forms, “both important,” have undergone fairly extensive clinical investigation.
In the first, spinal cord-derived neural stem cells are transplanted into the spinal cord.
“The people that drive this work are convinced this is not stem cells that turn into motor neurons and replace lost or failing motor neurons, but instead these are stem cells that provide an environment that is more favorable for sick motor neurons,” Dr. Pascuzzi said. “They secrete nerve growth factors and transport proteins to improve the environment.”
The second approach, autologous stem cell treatment, is a “culture-based method for inducing mesenchymal stem cells to secrete neurotrophic factors,” he said, which has been “shown to be protective in several animal models of neurodegenerative diseases.”

Impact of a literacy-sensitive intervention on CRC screening knowledge, attitudes, and intention to screen
Background Colorectal cancer (CRC) screening rates remain low, especially among low-income populations.
Objective To determine if a CRC screening intervention (video, brochure) improves knowledge about CRC and CRC screening, attitudes toward screening, and intention to complete CRC screening among average-risk adults with different health literacy skills, seeking medical care at a Federally Qualified Health Center (FQHC).
Methods Average-risk adults (50 years or older) who were not within CRC screening guidelines completed face-to-face pre- and post-intervention interviews that focused on knowledge about CRC and CRC screening, attitudes toward CRC screening, and intention to complete CRC screening.
Results Of the 270 participants, 64% were women, 72% were black/African American, 86% were not married, 79% had an annual household income of <$20,000, and 57% did not have health insurance. Reading levels by Rapid Estimate of Adult Literacy in Medicine health literacy test were: 3rd grade or lower, 17 participants (6.3%); 4th-6th grade, 27 (10.0%); 7th-8th grade, 101 (37.4 %); and high school, 125 (46.3%). CRC screening knowledge mean score improved, and perceived CRC susceptibility and self-efficacy to complete screening significantly increased, irrespective of health literacy (all P < .01). There were no significant changes in other attitudes or intention to complete screening.
Limitations The study was conducted in a single FQHC, so the results may not be generalizable to other health centers or populations of low-income and minority patients.
Conclusion A CRC screening intervention improved CRC screening knowledge and attitudes across levels of health literacy and may be an important strategy for improving CRC screening in the primary care setting.

Liraglutide lessens risk of kidney disease progression in type 2 diabetes
CHICAGO – Liraglutide reduced the risk of kidney disease progression in patients with type 2 diabetes, a study showed.
The latest results from the LEADER (Liraglutide Effect and Action in Diabetes: Evaluation of Cardiovascular Outcome Results) trial build on the previously reported success of liraglutide in reducing the risk of adverse cardiovascular events in people with type 2 diabetes.
“We now have drugs that not only lower blood sugar but also have an impact on new development of diabetic kidney disease and cardiovascular disease,” said Johannes Mann, MD, of the University of Erlangen-Nürnberg, Erlangen, Germany, in a plenary presentation at the meeting sponsored by the American Society of Nephrology.
The LEADER trial involved people with type 2 diabetes mellitus (mean duration, about 13 years) with a baseline hemoglobin A1c level greater than or equal to 7%. Some had never taken antidiabetic drugs, and some were taking oral antidiabetic drugs and/or basal/premixed insulin. They were either 50 years of age or older with established cardiovascular disease and chronic kidney disease, or 60 years and older with risk factors for cardiovascular disease.
Exclusion criteria included type 1 diabetes; a history of medication with glucagonlike peptide–1 receptor agonists, dipeptidyl peptidase–4 inhibitors, pramlintide, or rapid-acting insulin; and a family/personal history of multiple endocrine neoplasia type 2 or medullary thyroid cancer.
The 9,340 subjects were randomized in a double-blind fashion to daily subcutaneous injection with 0.6-1.8 mg of liraglutide (4,668) or placebo (4,672) for at least 3.5 years to a maximum treatment time of 5 years. The mean follow-up was 3.8 years.
At baseline, microalbuminuria had been diagnosed in 26.4% and 26.6% of those randomized to liraglutide or placebo, respectively. The respective baseline rates of macroalbuminuria were 10% and 11%. An estimated glomerular filtration rate (eGFR) less than 60 mL/min per 1.73 m2 was present in 23.9% of the liraglutide group and 22.3% of the control group.
In this analysis of the LEADER results, the primary renal outcome was a composite of the development of macroalbuminuria, doubling of serum creatinine, end-stage renal disease, or renal death. Liraglutide was superior to placebo in delaying the time to the primary outcome (hazard ratio, 0.78; 95% confidence interval, 0.67-0.92; P equal to .003). The outcome was driven by the reduction in development of macroalbuminuria (HR, 0.74; 95% CI, 0.60-0.91; P = .004), with treatment not being significantly effective for doubling of serum creatinine (HR, 0.89; 95% CI, 0.67-1.19) or the need for dialysis (HR, 0.87; 95% CI, 0.61-1.24).
The eGFR declined less in the liraglutide arm. The renal protection of the drug was restricted to subjects with a baseline eGFR of 30-59 mL/min per 1.73 m2. Liragutide was not associated with an increased risk of adverse renal events.
The latest results extend the potential indications of the therapeutic prowess of liraglutide in type 2 diabetes patients with chronic kidney disease, with the caveat that the significance of the primary outcome was due to macroalbuminuria rather than the arguably more important outcomes of doubling of serum creatinine and development of end-stage renal disease.
The trial was sponsored and funded by Novo Nordisk, the maker of liraglutide (Victoza) and the National Institutes of Health. Dr. Mann disclosed financial relationships with various drug companies, including Novo Nordisk.

MACRA final rule – 2017 is a transition year
This October, CMS released the final rule implementing the provisions of the Medicare Access and CHIP Reauthorization Act (MACRA). AGA is reviewing the 2,398-page regulation and will release a summary of key provisions impacting gastroenterologists in the coming weeks.
• When do changes take effect? Services provided beginning on Jan. 1, 2017, will directly impact reimbursement provided in 2019, the first year in which the MIPS program and APMs are effective.
• What should I do right now? AGA’s MACRA resource center (www.gastro.org/MACRA) provides customized advice based on your practice situation.
• What’s next? Over the coming weeks and months, we will provide detailed information and resources to help practices prepare for the upcoming policy and delivery changes.
Join AGA for our upcoming MACRA webinar series to hear from experts about how MACRA will affect you and your practice. Stay tuned for more information about dates and time. Keep reading below for an overview of the final rule and how it will affect your practice.
Final rule overview
• MACRA implementation will not be delayed. The first performance period begins Jan. 1, 2017, which CMS describes as a “transition year.” However, the final rule provides additional details on CMS’ plan to allow physicians to pick their pace of participation under MIPS (see below).
• Merit-based Incentive Programs (MIPS). CMS lowered the cost performance category to 0% in the 2017 transition period and gave clinicians three reporting options under MIPS and one under Advanced Alternative Payment Models (APMs).
• Option one: Report to MIPS for a full 90-day period or full year on quality, clinical performance improvement activities (CPIA), and advancing care (EHR), and maximize the chance to qualify for positive payment adjustments.
• Option two: Report less than a year, but for the full 90-day period on one quality measure, more than one CPIA, or more than the required measures in advancing care information to avoid penalties and receive a possible positive update.
• Option three: Report one quality measure, one CPIA, or report measures of advancing care to avoid penalty.
• Option four: Join an Advanced APM (see below).
Bottom line: If you do not report at least some data in 2017, you will be penalized.

How to Tweet: a guide for physicians
Social media, and Twitter in particular, is reshaping the practice of medicine by bringing physicians, scientists, and patients together on a common platform. With the pressures for providers to remain current with new clinical developments within the framework of health reform and to navigate the shift from volume- to value-based, patient-centered care, immediate access to a dynamic information-exchange medium such as Twitter can have an impact on both the quality and efficiency of care.

Should surgeons change gloves during total laparoscopic hysterectomy?
ORLANDO – Many gynecologic surgeons change gloves, gowns, and even surgical drapes during total laparoscopic hysterectomy to prevent bacterial infections, but little data support the practice.
In a small study of women undergoing total laparoscopic hysterectomy, investigators found that the overall risk of infection from contaminated gowns, gloves, and instruments was very low, with bacterial growth below the infection threshold in 98.9% of samples and no surgical site infections reported during 6 weeks of follow-up after surgery.
“Tradition dictates that even after both fields have been prepped, we refer to the perineum and vagina as ‘dirty,’ and the abdomen as ‘clean,’ ” Dr. Shockley said, “And surgeons habitually change their gown and gloves when inadvertent contact with the perineum or vagina occurs.”
To elucidate the true pathogen picture, Dr. Shockley and her colleagues assessed 31 women undergoing total laparoscopic hysterectomy for a benign indication during 2016. They evaluated the type and quantity of bacteria found intraoperatively on the abdomen, vagina, surgical gloves, instrument tips, and uterus.
All patients received perioperative antibiotic prophylaxis and standard, separate perineovaginal and abdominal prep with chlorhexidine. Investigators swabbed the vaginal fornices and abdomen at six sites, as well as the surgeon’s gloves following placement of the uterine manipulator, tips of instruments used to close the vaginal cuff, uterine fundus after extraction, and surgeon’s gloves following removal of the uterus.
They detected no anaerobic bacterial growth from samples taken from the abdomen, in the vagina, or on the tips of instruments used for cuff closure. Similarly, there was no aerobic growth observed in the vagina of any patient. However, they did detect aerobic bacterial growth in the abdomen, which in all cases was consistent with skin flora.
Three patients demonstrated some growth with the surgeon’s gloves following manipulator placement. Nearly one-third – 32% – of surgeon’s gloves cultured bacteria after removal of the uterus. One sample yielded cumulative growth for a bacterial count considered high enough to potentially cause infection, defined as more than 5,000 colony-forming units (CFU) per milliliter. This was the highest growth sample out of the 180 samples collected.
Additionally, 39% of samples from the uterine fundus were positive, a higher percentage than at any other site, Dr. Shockley reported. “And the one sample with growth exceeding 5,000 CFU/mL – you guessed it – was from the same patient.”
Bacterial growth was scant on the instrument tips used to close the vaginal cuffs.
Overall, bacterial growth in 98.9% of samples was below the infection threshold. “We did not identify any post–surgical site infections during 6 weeks of follow-up,” Dr. Shockley said at the meeting sponsored by AAGL.
“This study does provide a good description and count of the bacteria encountered during total laparoscopic hysterectomy. They are unlikely to cause surgical site infections … but based on concentration and frequency of bacterial growth on the surgeon’s gloves after specimen extraction, we would recommend if you are going to change gloves, do it after this step, before turning your attention back to the abdomen for vaginal cuff closure,” she said.
But changing gloves after placing the Foley and uterine manipulator “seems to be a wasted exercise,” Dr. Shockley said. “There was no growth on the vaginal fornices of any patient.”
The bacteria on the gloves in those three cases developed very low colony counts. “Yes, there was growth after the removal of the specimen, but with the exception of one patient, the colony counts were all below 5,000,” she said. “I think we need more data to reassure ourselves [attire changes are] unnecessary at every step of the [total laparoscopic hysterectomy].”
The study was supported by an educational grant from the Foundation of the AAGL Jerome J. Hoffman Endowment. Dr. Shockley reported having no relevant financial disclosures.
ORLANDO – Many gynecologic surgeons change gloves, gowns, and even surgical drapes during total laparoscopic hysterectomy to prevent bacterial infections, but little data support the practice.
In a small study of women undergoing total laparoscopic hysterectomy, investigators found that the overall risk of infection from contaminated gowns, gloves, and instruments was very low, with bacterial growth below the infection threshold in 98.9% of samples and no surgical site infections reported during 6 weeks of follow-up after surgery.
“Tradition dictates that even after both fields have been prepped, we refer to the perineum and vagina as ‘dirty,’ and the abdomen as ‘clean,’ ” Dr. Shockley said, “And surgeons habitually change their gown and gloves when inadvertent contact with the perineum or vagina occurs.”
To elucidate the true pathogen picture, Dr. Shockley and her colleagues assessed 31 women undergoing total laparoscopic hysterectomy for a benign indication during 2016. They evaluated the type and quantity of bacteria found intraoperatively on the abdomen, vagina, surgical gloves, instrument tips, and uterus.
All patients received perioperative antibiotic prophylaxis and standard, separate perineovaginal and abdominal prep with chlorhexidine. Investigators swabbed the vaginal fornices and abdomen at six sites, as well as the surgeon’s gloves following placement of the uterine manipulator, tips of instruments used to close the vaginal cuff, uterine fundus after extraction, and surgeon’s gloves following removal of the uterus.
They detected no anaerobic bacterial growth from samples taken from the abdomen, in the vagina, or on the tips of instruments used for cuff closure. Similarly, there was no aerobic growth observed in the vagina of any patient. However, they did detect aerobic bacterial growth in the abdomen, which in all cases was consistent with skin flora.

GLAGOV finds evolocumab plus statin drives unprecedented plaque regression
NEW ORLEANS – Adding the PCSK9 inhibitor evolocumab to maximum tolerated statin therapy in subjects with symptomatic coronary disease induced atheromatous plaque regression of a previously unheard-of scale in the phase III GLAGOV trial, Steven E. Nissen, MD, reported at the American Heart Association scientific sessions.
Over 18 months of follow-up, percent atheroma volume was unchanged in patients treated with maximum tolerated statin therapy. But in patients on maximum tolerated statin therapy plus evolocumab, mean atheroma volume decreased by 0.95%. A reduction in atheroma volume as small as 0.5% has been associated with a reduced rate of cardiovascular events in previous studies, according to GLAGOV principal investigator Stephen J. Nicholls, MBBS, PhD, of the University of Adelaide in Australia.
Total atheroma volume was reduced by 5.8 mm3 with dual therapy, compared with a nonsignificant 0.9-mm3 decrease in patients on statin monotherapy.
Among 423 patients on statin monotherapy, 47% had regression and 53% had progression of atheroma volume. In contrast, 64% of 423 patients on a statin plus evolocumab had atheroma regressions and 36% had atheroma progression.
What’s more, plaque regression was directly related to declines in LDL levels.
“We saw a linear relationship between lower LDL and greater regression with no tailing off of benefit at very low LDL levels. Down to 20 mg/dL, it’s continuous and linear,” the cardiologist said. “I thought there might be diminishing return at low LDL levels. We don’t see that.”
GLAGOV (Global Assessment of Plaque Regression with a PCSK9 antibody as Measured by Intravascular Ultrasound) was a double-blind, placebo-controlled, randomized trial including 846 evaluable patients with symptomatic CAD at 197 centers. All were on a stable maximum tolerated dose of a statin at baseline, at which point they underwent intravascular ultrasound (IVUS) and were assigned to subcutaneous evolocumab (Repatha) at 420 mg once monthly or placebo injections while continuing on their statin. At 18 months, participants had a follow-up IVUS of the originally imaged target vessel.
The mean LDL-cholesterol level was 93 mg/dL at the start of the study. With the addition of evolocumab, the mean LDL level dropped to 37 mg/dL; that’s a 60% further reduction below the level on statin alone.
The investigators conducted a post hoc exploratory subgroup analysis confined to 144 patients whose baseline LDL on statin monotherapy was less than 70 mg/dL. In this group, the addition of evolocumab caused the mean LDL level to plunge to 24 mg/dL. Mean atheroma volume in dual-treatment patients with a baseline LDL below 70 mg/dL decreased by 1.97% – double the reduction seen in the overall statin/evolocumab study arm. Further, 81% of patients on dual therapy who started out with an LDL below 70 mg/dL showed IVUS evidence of plaque regression, compared with 48% of those on statin monotherapy. For those whose baseline LDL level was below 70 mg/dL and who remained on statin monotherapy, there was no change in atheroma volume over time.
No signals of any safety concerns arose in the group on a statin plus evolocumab. Of particular interest, there was no increase in new-onset diabetes, neurocognitive dysfunction, or myalgia in patients given dual therapy, compared with patients on a statin alone.
Dr. Santos, of the University of Sao Paolo in Brazil, noted that GLAGOV wasn’t powered to provide evidence of long-term safety or of hard clinical endpoints such as acute MI. For those outcomes, physicians must await the soon-to-come results of the nearly 28,000-patient FOURIER clinical outcomes trial.
The GLAGOV trial was sponsored by Amgen, the maker of evolocumab (Repatha). Dr. Santos reported serving as a consultant to and paid researcher for the company. Dr. Nissen reported serving as a consultant to Amgen and several other companies; any resultant consultant fees are directly paid to charities. Dr. Nicholls reported receiving research support from and serving as a consultant to Amgen and several other drug companies.
Simultaneously with Dr. Nissen’s presentation in New Orleans, the GLAGOV results were published online (JAMA. 2016 Nov 15. doi: 10.1001/jama.2016.16951).
