BOSTON – Patients with primary biliary cholangitis (PBC) who have compensated cirrhosis fared just as well on obeticholic acid (OCA) as did PBC patients without cirrhosis, according to an analysis of data from POISE, the pivotal clinical trial for approval of OCA for PBC.

The POISE trial included 36 individuals with PBC and compensated cirrhosis, since cirrhosis “is an endpoint for virtually all liver diseases,” John Vierling, MD, said in a video interview at the meeting.

“Significantly more OCA-treated patients with cirrhosis achieved the primary composite endpoint compared to placebo,” Dr. Vierling and his coauthors wrote in a poster presented at the annual meeting for the American Association for the Study of Liver Diseases. The difference was individually significant for all three values that made up the composite primary endpoint as well.

Secondary endpoints included gamma-glutamyltransferase, alanine aminotrasferase, and aspartate aminotransferase, all of which were significantly reduced among patients taking OCA. Patients on placebo saw these values rise over the time period of the study.

There were no new safety signals seen in the post hoc analysis of the group with cirrhosis that were not seen in the trial at large, said Dr. Vierling. Two individuals in the subgroup dropped out of the trial because of pruritis, a similar proportion to that seen in the full trial population.

The drug’s manufacturer, Intercept Pharmaceuticals, is working with the Food and Drug Administration to establish appropriate doses and intervals for obeticholic acid so it may be used safely in individuals with decompensated cirrhosis, said Dr. Vierling.

Obeticholic acid, a farnesoid-X receptor agonist, is an approved agent to use as add-on therapy to ursodeoxycholic acid (UDCA), or as monotherapy for patients who can’t tolerate UDCA.

Dr. Vierling disclosed financial relationships with Intercept Pharmaceuticals and with several other pharmaceutical companies. The study was funded by Intercept Pharmaceuticals.

WASHINGTON – Tumor necrosis factor inhibitors don’t appear to confer any additional cancer risk upon children with juvenile idiopathic arthritis above the increased incidence of cancer that comes hand in hand with the disease itself.

In 2009, the drugs came under suspicion of boosting the already-known increased cancer risk in these patients, Timothy G. Beukelman, MD, said at the annual meeting of the American College of Rheumatology. But the large database review that he conducted with his colleagues doesn’t validate those fears.

“I feel fairly confident now that I can stand in front of parents and say that we can treat their child effectively without putting that child at an even higher risk of a malignancy,” he said in a video interview.

WASHINGTON – Biologic agents should be stopped prior to elective total knee or hip arthroplasty in patients with rheumatic diseases, according to a draft guideline developed by the American College of Rheumatology and the American Association of Hip and Knee Surgeons.

The guideline, which address the perioperative management of antirheumatic medications in patients with rheumatoid arthritis, spondyloarthritis, psoriatic arthritis, juvenile idiopathic arthritis (JIA), or lupus who are undergoing such surgery, is currently under review, Dr. Susan Goodman, MD, coprincipal investigator, reported at the annual meeting of the American College of Rheumatology.

The draft guideline was created because “guidance was needed for common clinical situations, even where data were sparse. We didn’t want to configure treatment mandates – that’s not what these are,” Dr. Goodman of Cornell University, New York, said.

The recommendations are conditional, she said, meaning that the benefits probably outweigh the harms, that the recommendations apply to most but not all patients, and that future research may lead to changes.

“They’re also preference sensitive,” she said, explaining that patients’ values and preferences should be carefully considered, as they might differ from those of the patient panel consulted during guideline development; the panel expressed greater concern about the risk of infection following surgery than about perioperative flares resulting from medication discontinuation.

Based on agreement by at least 80% of a voting panel which considered available evidence in the context of their clinical experience along with the input from the patient panel, the draft guideline states that:

• Current doses of methotrexate, leflunomide, hydroxychloroquine, and sulfasalazine should be continued in patients with rheumatic diseases undergoing elective hip and knee replacement. This recommendation is based on an extensive literature review that showed the infection rate is decreased in patients who continue these medications, Dr. Goodman said.

• All biologics should be withheld prior to surgery in patients with inflammatory arthritis, and surgery should be planned for the end of the dosing cycle. This matter wasn’t specifically addressed in the literature; however, numerous randomized controlled trials outside of the surgical setting demonstrate an increased risk of infection associated with their use, she noted.

“All of the biologic medications were found to be associated with an increased risk of infection,” she said. “Because of this and the level of importance patients place on minimizing infection risk, we’ve recommended that biologics be withheld prior to surgery.”

• Tofacitinib, which was considered in a separate oral, targeted therapy category, should be withheld for at least 7 days prior to surgery in patients with RA, spondyloarthritis, and JIA. Data from systematic reviews and meta-analyses showed an increased risk of infection with tofacitinib, although more research is needed in order to “firm up” this recommendation, Dr. Goodman said.

• In lupus patients, rituximab and belimumab should be withheld prior to surgery, and surgery should be planned for the end of the dosing period.

“Again, this was not answered in the literature. We depended on observational studies that we reviewed that did show that patients with severe active lupus were at much higher risk for adverse events. But since rituximab isn’t approved by the [Food and Drug Administration] for use in lupus, and belimumab isn’t approved for use in severe lupus – and those seem to be the high-risk patients – we thought withholding them was more prudent,” she said.

• Patients with severe lupus should continue on current doses of methotrexate, mycophenolic acid, azathioprine, mizoribine, cyclosporine, and tacrolimus through surgery. This recommendation is based on indirect data from experience in organ transplant patients.

• All medications should be discontinued in patients whose lupus is not severe.

“Our recommendation is to withhold for 7 days to 2-5 days after surgery in the absence of any wound healing complications or any other complications,” she said, noting that the literature does not directly address this; the recommendation is based on indirect evidence in patients with either active infection or who are at risk for infection.

“We thought that careful monitoring of the patient would permit us to identify flare and intervene quickly. … and that, for mild cases of lupus, the morbidity associated with infection might not be greater than the morbidity associated with the disease flare,” she said.

• Biologics should be restarted once surgical wounds show evidence of healing and there is no clinical evidence of infection. The literature does not directly address this; the recommendation is based on the rationale for use of these medications in patients with either active infection or risk for infection.

• Current daily doses of glucocorticoids, rather than supraphysiologic doses, should be continued in adults with RA, lupus, or inflammatory arthritis. A meta-analysis and systematic review of randomized controlled trial data and observational data showed no hemodynamic difference between daily doses and stress doses.

“In addition, there are abundant observational data demonstrating an increase in infection in patients on chronic steroids greater than 15 mg, and we thought that part of the optimization of the patient would be getting them on the lowest possible steroid dose,” she said, stressing that this refers only to adults receiving glucocorticoids for their rheumatic disease, and not to those with a history of JIA who may have received steroids during development, or to those receiving glucocorticoids for primary, adrenal, or hypothalamic disease.

According to Dr. Goodman, the time is right for the introduction of these recommendations, because the increased use of disease-modifying drugs and biologics means that most patients coming in for these surgeries will be taking these medications.

Further, despite the widespread use of the medications, the rate of total knee and hip arthroplasty surgeries among patients with rheumatic diseases is about the same as it was 20 or 30 years ago – and their risk for devastating complications, including infections, remains high, she said, noting that appropriate medication management provides an opportunity to mitigate risk.

Coprincipal investigator, Bryan Springer, MD, further emphasized the importance of the guideline, noting that the 5-year survival among rheumatic disease patients who develop certain perioperative complications is lower than for many common cancers, and that the literature offers little guidance on managing medications in the perioperative period.

“We now have a document that’s based on the available evidence, and also based on expert opinion, to help us manage these patients much more thoroughly in the perioperative period,” Dr. Springer, an orthopedic surgeon in Charlotte, N.C., said during a press briefing on the guideline.

Dr. Springer highlighted the value of the unique collaboration between the ACR and the AAHKS, calling the effort a win both for patients, and for “collaborative efforts, collaborative research, which we just really don’t do enough of,” he said. “I hope this is a huge step towards that direction.”

NEW ORLEANS – A single 300-mg injection of inclisiran, a novel non–monoclonal antibody PCSK9 inhibitor, plus statin therapy, achieved a mean 51% reduction in LDL cholesterol, compared with placebo plus a statin, an effect sustained for 90 days.

Moreover, a second subcutaneous 300-mg dose given at day 90 resulted in a 57% reduction in LDL sustained at day 180 with a highly favorable safety profile in the phase II ORION-1 study, Kausik K. Ray, MD, reported at the American Heart Association scientific sessions.

“The efficacy, safety and dosing profile of inclisiran are likely to ensure significant and durable reductions in LDL-C and thus could potentially impact cardiovascular outcomes,” said Dr. Ray, professor of public health at Imperial College London.

Inclisiran is a synthetic RNA interference agent. After injection it selectively goes to the liver, bypassing other tissues and thereby limiting toxicity. Inclisiran halts PCSK9 protein synthesis in the liver, with a resultant sharp, steep, and sustained drop in LDL levels.

Inclisiran achieves LDL lowering of a magnitude similar to that of the PCSK9-inhibiting monoclonal antibodies alirocumab (Praluent) and evolocumab (Repatha), but it will be less expensive to produce and far less costly to administer than the monoclonal antibodies. Dosing is planned to be two or three injections per year, rather than every 2 or 4 weeks, as with the PCSK9 inhibitor monoclonal antibodies, which cost a hefty $14,000 per year. And the sustained efficacy of a dose of inclisiran should make patient adherence to LDL-lowering therapy less of an issue, Dr. Ray continued.

ORION-1 (Inhibition of PCSK9 Synthesis Via RNA Interference) was a double-blind, randomized, placebo-controlled trial comprising 501 patients already on maximally tolerated statin therapy for atherosclerotic cardiovascular disease or at high risk. Nevertheless, their baseline LDL was 125-135 mg/dL. Participants were randomized to one of six doses of inclisiran or placebo. At 90 days they received a second dose. Dr. Ray presented 90- and 180-day outcomes.

This was primarily a safety and dose-ranging study. Side effects at 90 days were no different from placebo regardless of whether patients received 100, 200, 300, or 500 mg of inclisiran. There was no signal of a problem with myalgia or elevated liver enzymes. Mild injection site reactions lasting for more than 4 hours occurred in 1.5%-3.3% of inclisiran-treated patients, but not in a dose-dependent fashion.

One 300-mg dose of inclisiran, in addition to achieving a mean 51% reduction in LDL from baseline at day 90, resulted in a mean 28% reduction in total cholesterol, a modest 10% drop in triglycerides, a 9% increase in HDL, a 37% drop in Apo-B, and a median 23% reduction in Lp(a). Plasma PCSK9 levels plunged in parallel with LDL.

The mean drop in LDL from baseline at day 180 after two 300-mg doses of inclisiran spaced 90 days apart was 65 mg/dL. The LDL reduction ranged from a minimum of 26.5 mg/dL to a maximum of 122 mg/dL.

Dr. Ray’s presentation of the ORION-1 findings followed on the heels of publication of a positive but much smaller phase I study of inclisiran (N Engl J Med. 2016 Nov 13. doi: 10.1056/NEJMoa1609243).

A large phase II clinical trial with cardiovascular outcomes is planned.

Discussant Borge G. Nordestgaard, MD, could find no fault with ORION-1 or inclisiran’s performance to date.

NEW ORLEANS – A single 300-mg injection of inclisiran, a novel non–monoclonal antibody PCSK9 inhibitor, plus statin therapy, achieved a mean 51% reduction in LDL cholesterol, compared with placebo plus a statin, an effect sustained for 90 days.

Moreover, a second subcutaneous 300-mg dose given at day 90 resulted in a 57% reduction in LDL sustained at day 180 with a highly favorable safety profile in the phase II ORION-1 study, Kausik K. Ray, MD, reported at the American Heart Association scientific sessions.

“The efficacy, safety and dosing profile of inclisiran are likely to ensure significant and durable reductions in LDL-C and thus could potentially impact cardiovascular outcomes,” said Dr. Ray, professor of public health at Imperial College London.

Inclisiran is a synthetic RNA interference agent. After injection it selectively goes to the liver, bypassing other tissues and thereby limiting toxicity. Inclisiran halts PCSK9 protein synthesis in the liver, with a resultant sharp, steep, and sustained drop in LDL levels.

Inclisiran achieves LDL lowering of a magnitude similar to that of the PCSK9-inhibiting monoclonal antibodies alirocumab (Praluent) and evolocumab (Repatha), but it will be less expensive to produce and far less costly to administer than the monoclonal antibodies. Dosing is planned to be two or three injections per year, rather than every 2 or 4 weeks, as with the PCSK9 inhibitor monoclonal antibodies, which cost a hefty $14,000 per year. And the sustained efficacy of a dose of inclisiran should make patient adherence to LDL-lowering therapy less of an issue, Dr. Ray continued.

ORION-1 (Inhibition of PCSK9 Synthesis Via RNA Interference) was a double-blind, randomized, placebo-controlled trial comprising 501 patients already on maximally tolerated statin therapy for atherosclerotic cardiovascular disease or at high risk. Nevertheless, their baseline LDL was 125-135 mg/dL. Participants were randomized to one of six doses of inclisiran or placebo. At 90 days they received a second dose. Dr. Ray presented 90- and 180-day outcomes.

This was primarily a safety and dose-ranging study. Side effects at 90 days were no different from placebo regardless of whether patients received 100, 200, 300, or 500 mg of inclisiran. There was no signal of a problem with myalgia or elevated liver enzymes. Mild injection site reactions lasting for more than 4 hours occurred in 1.5%-3.3% of inclisiran-treated patients, but not in a dose-dependent fashion.

One 300-mg dose of inclisiran, in addition to achieving a mean 51% reduction in LDL from baseline at day 90, resulted in a mean 28% reduction in total cholesterol, a modest 10% drop in triglycerides, a 9% increase in HDL, a 37% drop in Apo-B, and a median 23% reduction in Lp(a). Plasma PCSK9 levels plunged in parallel with LDL.

The mean drop in LDL from baseline at day 180 after two 300-mg doses of inclisiran spaced 90 days apart was 65 mg/dL. The LDL reduction ranged from a minimum of 26.5 mg/dL to a maximum of 122 mg/dL.

Dr. Ray’s presentation of the ORION-1 findings followed on the heels of publication of a positive but much smaller phase I study of inclisiran (N Engl J Med. 2016 Nov 13. doi: 10.1056/NEJMoa1609243).

A large phase II clinical trial with cardiovascular outcomes is planned.

Discussant Borge G. Nordestgaard, MD, could find no fault with ORION-1 or inclisiran’s performance to date.

NEW ORLEANS – Results of a new 40,000-patient Swedish observational study provide the strongest evidence to date suggesting a causal relationship between bariatric surgery and reduced risk of heart failure, according to Johan Sundström, MD.

The study, which included patients drawn from two large Swedish national registries, demonstrated that bariatric surgery was associated with a 46% reduction in the incidence of heart failure during a median 4.1 years of follow-up, compared with an intensive lifestyle modification program for weight loss.

“These are observational data, but it’s a very large study population – and probably there will never be a large randomized trial of bariatric surgery versus weight loss through intensive lifestyle modification as a means of reducing the risk of heart failure,” Dr. Sundström, professor of epidemiology and a cardiologist at Uppsala (Sweden) University, said at the American Heart Association scientific sessions.

The study included 25,804 bariatric surgery patients in SOReg, the Scandinavian Obesity Surgery Registry, and a matched comparator group of 13,701 participants in a Swedish national registry of obese participants in a commercial Sweden-based intensive structural lifestyle modification program for weight loss called Itrim. The two groups were matched for baseline body mass index, which was a mean of 41.5 kg, and numerous other demographic factors and comorbid conditions. Participants weighed an average of 119 kg at baseline. None of the subjects had a history of heart failure.

The bariatric surgery group lost substantially more weight than did the lifestyle modification group: an average loss of about 35 kg after 1 year, which was 18.8 kg more than in the lifestyle modification group. After 2 years, the bariatric surgery group had an average of 22.6 kg more weight loss than did the comparison group.

The primary outcome was hospitalization for new-onset heart failure during a median 4.1 years of follow-up. Subjects were well below the age range when the incidence of heart failure accelerates – they averaged 41 years of age – but 73 of them did develop heart failure during follow-up. The incidence was 46% lower in the bariatric surgery patients. This supports the study hypothesis that bariatric surgery leads to a low incidence of new-onset heart failure, compared with intensive lifestyle modification because of its larger weight loss effect.

When Dr. Sundström and his coinvestigators combined the two study groups, they found that a 10-kg weight loss at 1 year was associated with a 23% reduction in the risk of heart failure during follow-up, irrespective of whether the weight loss was achieved surgically or through the lifestyle program.

“A great way of studying causality is to take away the exposure and note what happens to the outcome. If there’s a causal link, then if you take away the risk factor – in this case, obesity – the disease should go away,” he explained in a video interview.

The reduced risk of heart failure in the bariatric surgery patients wasn’t because of fewer acute MIs. Indeed, their acute MI rate during follow-up was similar to that of the lifestyle modification group. But bariatric surgery was associated with relative risk reductions of 35%-37% for atrial fibrillation or need for diabetes or blood pressure–lowering medications at 1 year – and atrial fibrillation, diabetes, and hypertension are all established risk factors for heart failure, Dr. Sundström noted.

The Itrim intensive lifestyle modification program entailed an initial very-low-energy diet for the first 3 months in order to achieve massive weight loss, followed by a 9-month maintenance program involving motivational counseling, exercise, behavioral therapy, and a restricted diet.

Dr. Sundström said he and his coinvestigators plan to continue the study and expand it to look at differences in additional cardiovascular endpoints as patients age.

The study was funded by the U.S. National Institute of Diabetes and Digestive and Kidney Diseases, Uppsala University, the Karolinska Institute, and the Swedish Research Council. Dr. Sundström reported serving as a scientific advisor to Itrim.

NEW ORLEANS – The puzzle of how to safely prevent thrombotic events in patients with atrial fibrillation who receive a coronary stent now has a little more clarity in the era of new oral anticoagulants.

The first randomized trial to compare the safety of a new oral anticoagulant (NOAC, in this case rivaroxaban) against warfarin when paired with one or more antiplatelet drugs showed that the NOAC edged out warfarin for safety by cutting the rate of clinically significant bleeding events while preventing thrombotic events roughly as well as warfarin.

NEW ORLEANS – Patients undergoing coronary artery bypass graft (CABG) surgery do not see any 5-year survival advantage when their surgeon uses both internal mammary (thoracic) arteries for grafting rather than just one of them along with a vein, finds an interim analysis from the randomized Arterial Revascularization Trial (ART).

Overall, about 8.5% of the 3,102 patients randomized had died 5 years after surgery, with no significant difference between the bilateral graft and single graft groups, according to data reported at the American Heart Association scientific sessions and simultaneously published (N Engl J Med. 2016 Nov 14. doi: 10.1056/NEJMoa1610021). The former had roughly triple the rate of sternal reconstruction, mainly driven by complications in insulin-dependent diabetes patients having high body mass index.

Pointed questions

The lack of difference was possibly due to a very high level of guideline-based medical therapy in the trial (which may have especially protected the vein grafts) or to the fact that the annual failure rate of vein grafts is modest and steady up to 5 years but accelerates thereafter, Dr. Taggart proposed. The trial’s primary outcome of 10-year survival, expected in 2018, will likely differ, speculated Dr. Sellke, who is also program chair for the AHA scientific sessions.

“Do you think multiple arterial grafting is superior to single internal mammary artery grafting considering the lack of improvement in survival and other outcomes in the study, with the increase in sternal wound infections?” he asked.

“I personally, if I needed the operation, would insist on having bilateral internal mammary artery grafts done by an experienced operator because it is totally counterintuitive to believe that having more patent grafts in your heart at 10 to 20 years of follow-up is of no benefit,” Dr. Taggart maintained.

When data meet clinical practice

It may require time for the benefit of the bilateral artery graft to emerge, he agreed. “I’m undeterred from my belief that ... in patients who are getting CABG done in their 40s or 50s or early 60s, betting on a graft that’s going to outperform vein grafts is the better strategy.”

Until the trial’s 10-year results become available, physicians may wish to put these interim results in the context when counseling patients, according to Dr. Gardner.

“We have indisputable evidence that arterial grafts have better long-term patency than vein grafts,” he elaborated. “If we had a very sophisticated patient, we might tell them that we were a little surprised that this head-to-head trial of single versus double didn’t show any survival benefit at 5 years, but we still are persuaded by the data that shows the better patency, and we think in the situation that the patient’s in, that we would still recommend a double mammary, assuming that the patient doesn’t have comorbidities that would make that more dangerous.”

Trial details

ART enrolled patients from 28 cardiac surgical centers in seven countries. The patients, all of whom had multivessel coronary disease and were scheduled to undergo CABG, were randomized evenly to single or bilateral internal thoracic artery grafts.

The interim results showed differences in nonadherence to the randomized operation: 2.4% of patients in the single graft group ultimately underwent got bilateral grafts, whereas 14% of patients in the bilateral graft group ultimately got a single graft.

“This raises questions about how experienced some surgeons were with the use of bilateral internal mammary artery grafts,” Dr. Taggart commented.

At 5 years of follow-up, 8.7% of patients in the bilateral graft group and 8.4% of patients in the single graft group had died, a nonsignificant difference. “Those mortalities are similar to what has been observed in other contemporary trials of CABG,” he noted. There was no difference between diabetic and nondiabetic patients with respect to this outcome.

The rate of the composite outcome of death, myocardial infarction, or stroke was 12.2% in the bilateral graft group and 12.7% in the single graft group, also a nonsignificant difference.

On the other hand, patients in the bilateral graft group had higher rates of sternal wound complications (3.5% vs. 1.9%; P = .005) and sternal reconstruction (1.9% vs. 0.6%; P = .002).

The groups were statistically indistinguishable with respect to rates of mortality, major bleeding, or need for repeat revascularization, as well as angina status and quality of life measures, according to Dr. Taggart, who disclosed that he had no relevant conflicts of interest.

NEW ORLEANS – Blood pressure and cholesterol lowering in elderly patients with moderate vascular risk did not prevent cognitive decline in HOPE-3, the large randomized Heart Outcomes and Prevention Evaluation-3 trial, Jackie Bosch, PhD, reported at the American Heart Association scientific sessions.

Disappointing, but the study also brought some welcome glass-half-full good news: Although treatment did not slow cognitive decline, it didn’t worsen it, either, as some had feared. That means the clinically meaningful reduction in cardiovascular events conferred with blood pressure and cholesterol lowering previously reported in HOPE-3 does not come at the cost of an increased risk of dementia.
Rosuvastatin had no adverse effect on cognitive function in HOPE-3. This is an important finding, given the black box warning for statins mandated by the Food and Drug Administration, which was based only on observational postmarketing surveillance data,” observed Dr. Bosch of the Population Health Research Institute at McMaster University in Hamilton, Ont.

BOSTON – Obeticholic acid resulted in a significant reduction of a biomarker for liver fibrosis in patients with primary biliary cholangitis, according to a retrospective analysis of clinical trial data. In addition, patients taking obeticholic acid had a mean reduction in liver stiffness as measured by transient elastography.

Gideon Hirschfield, MD, PhD, presented the re-analysis of clinical trial data at the annual meeting of the American Association for the Study of Liver Diseases.

POISE was a phase III randomized, double-blind, placebo-controlled study of obeticholic acid for patients with primary biliary cholangitis (PBC). The clinical trial’s primary composite endpoint was an alkaline phosphatase level less than 1.67 times the upper limit of normal, with at least a 15% reduction in alkaline phosphatase and normal serum bilirubin.

The cohort of POISE patients on obeticholic acid met this biochemical surrogate endpoint, resulting in approval of the farnesoid X receptor agonist for treatment of PBC as an add-on to ursodeoxycholic acid (UDCA), or for patients who cannot tolerate UDCA.

However, transient elastography and the aspartate transaminase (AST) to platelet ratio index (APRI) have both been used to assess fibrosis in PBC, and have been found to predict clinical outcomes in PBC. These measures have the advantage of being noninvasive methods to measure the quality of liver tissue.

Dr. Hirschfield, a transplant hepatologist at the institute of immunology and immunotherapy at the University of Birmingham, England, and his coinvestigators reevaluated data from the POISE trial. They determined that APRI dropped significantly over 12 months of obeticholic acid treatment compared to placebo (P less than .01 for each of the two dosing arms of the POISE trial). Patients who switched to 5-10 mg of obeticholic acid daily from placebo during an open-label extension of POISE also had significant reductions in APRI scores (P less than .05); the reduction for placebo-switchers on a fixed 10-mg dose during the open-label study was not significant

Liver stiffness, as measured by transient elastography, was reduced for both arms of the POISE study at 12 months, but increased for those in the placebo arm. “Fewer patients receiving obeticholic acid 10 mg progressed” to a level associated with histological cirrhosis, “and patients receiving obeticholic acid showed an improvement in liver stiffness,” said Dr. Hirschfield.

Pruritis is a feature of PBC, and worsening pruritis can be a side effect of deoxycholic acid. However, the worsening is often transitory, so patients should be encouraged to try to stay the course, said Dr. Hirschfield. Managing patient expectations; sharing improved biomarkers; and considering the addition of a bile acid sequestrant or rifampicin, or reducing the obeticholic acid dose are all strategies to consider when caring for PBC patients, said Dr. Hirschfield.

Clinical trials to assess the safety and efficacy of obeticholic acid for individuals with nonalcoholic fatty liver disease and steatohepatitis are underway.

Dr. Hirschfield discussed his findings in a video interview.
