Bivalirudin not superior to heparin in real-world analysis
A new study suggests bivalirudin does not produce better outcomes than heparin in patients undergoing transradial primary percutaneous coronary intervention (PCI) for ST elevation myocardial infarction (STEMI).
Researchers found no significant difference in the rate of a composite of death, myocardial infarction, and stroke in patients who received bivalirudin or heparin, with or without glycoprotein (GP) IIb/IIIa inhibitors.
Likewise, the incidence of bleeding was not significantly different between the heparin and bivalirudin groups.
However, the rate of stent thrombosis was significantly higher in patients who received bivalirudin.
Ion S. Jovin, MD, of Virginia Commonwealth University in Richmond, and colleagues reported these results in JACC: Cardiovascular Interventions.
Using data from the National Cardiovascular Data Registry CathPCI Registry, the researchers examined the records of 67,368 patients with STEMI. The patients underwent primary PCI via radial access at 1584 sites between 2009 to 2015.
Patients received anticoagulation with bivalirudin (n=29,660) or heparin (n=37,708). Twenty-three percent (n=6781) of patients on bivalirudin received GP IIb/IIIa inhibitors, as did 59% of patients on heparin (n=22,416).
Results
In an unadjusted analysis, the researchers found no significant difference in the rate of the composite endpoint, which included death, myocardial infarction, and stroke. The incidence was 4.6% with bivalirudin and 4.7% with heparin (P=0.47).
However, patients who received bivalirudin had a significantly higher rate of acute stent thrombosis—1.03%—than patients who received heparin—0.602% (P<0.001).
And there were significantly fewer bleeding episodes with bivalirudin than with heparin—6.8% and 8.1%, respectively, (P<0.001).
The researchers adjusted their analysis for multiple variables, including a propensity score reflecting the probability of receiving bivalirudin to account for patient differences between groups.
After these adjustments, the odds ratio (OR) of the composite endpoint for bivalirudin versus heparin was 0.95 (P=0.152).
The OR ratio for acute stent thrombosis was 2.11 (P<0.001), and the OR for bleeding was 0.98 (P=0.57).
The researchers did note that, among patients who were not receiving GP IIb/IIIa inhibitors, outcomes were better in patients who received bivalirudin. They had a significantly lower risk of bleeding and the composite endpoint than patients who received heparin.
“Our sensitivity analysis provides some insights into direct comparisons of bivalirudin and heparin when GPIIb/IIIa inhibitors are forced out of the equation and suggests that, in the direct comparison, bivalirudin may have superior outcomes,” Dr Jovin said.
“However, our study showed that, in the real world, over a third of the patients with STEMI undergoing transradial PCI who receive heparin and about a fifth of patients who receive bivalirudin also receive GPIIb/IIIa inhibitors.”
The researchers suggested a need for a randomized trial in patients treated exclusively via transradial primary PCI and anticoagulated with bivalirudin versus heparin as well as a cost-effectiveness analysis comparing heparin and bivalirudin.

Drug receives breakthrough designation for relapsed/refractory AML
The US Food and Drug Administration (FDA) has granted GMI-1271 breakthrough therapy designation for the treatment of adults with relapsed/refractory acute myeloid leukemia (AML).
GMI-1271 is an E-selectin antagonist being developed by GlycoMimetics, Inc.
The product already has orphan and fast track designations from the FDA for the treatment of AML.
GMI-1271 is currently being evaluated in a phase 1/2 trial of patients with relapsed or refractory AML and patients age 60 and older with newly diagnosed AML.
The patients are receiving GM-1271 in combination with chemotherapy. The relapsed/refractory group is receiving mitoxantrone, etoposide, and cytarabine. The newly diagnosed patients are receiving cytarabine and idarubicin (7+3).
GlycoMimetics plans to present data from this trial at the 2017 American Society of Clinical Oncology (ASCO) Annual Meeting as abstracts 2520 and 2560.
The company also plans to present the research at the 22nd Congress of the European Hematology Association (EHA) as abstracts P547 and P203.
About breakthrough designation
The FDA’s breakthrough therapy designation is intended to expedite the development and review of new treatments for serious or life-threatening conditions.
Breakthrough designation entitles the company developing a therapy to more intensive FDA guidance on an efficient and accelerated development program, as well as eligibility for other actions to expedite FDA review, such as a rolling submission and priority review.
To earn breakthrough designation, a treatment must show encouraging early clinical results demonstrating substantial improvement over available therapies with regard to a clinically significant endpoint, or it must fulfill an unmet need.
About fast track designation
The FDA’s fast track program is designed to facilitate the development and expedite the review of products intended to treat or prevent serious or life-threatening conditions and address unmet medical need.
Through the fast track program, a product may be eligible for priority review. In addition, the company developing the product may be allowed to submit sections of the new drug application or biologic license application on a rolling basis as data become available.
Fast track designation also provides the company with opportunities for more frequent meetings and written communications with the FDA.
About orphan designation
The FDA grants orphan designation to products intended to treat, diagnose, or prevent diseases/disorders that affect fewer than 200,000 people in the US.
The designation provides incentives for sponsors to develop products for rare diseases. This may include tax credits toward the cost of clinical trials, prescription drug user fee waivers, and 7 years of market exclusivity if the product is approved.

New device that treats esophageal atresia in infants has been authorized
The FDA has authorized a medical device to treat infants up to age 1 year for esophageal atresia, called the Flourish Pediatric Esophageal Atresia Anastomosis.
The device uses magnets attached to two catheters to pull the upper and lower esophagus together, closing the gap for several days until a connection is formed. The catheters are then removed, and the infant can begin feeding via mouth.
Cook Medical provided data on 16 patients implanted with Flourish devices. All patients had successful joining of their esophagus within 3-10 days after receiving the device. A total of 13 of the 16 patients developed anastomotic stricture that required a balloon dilation procedure, a stent, or both to repair. Such strictures also occur with traditional surgery.
The Flourish device should not be used in patients older than 1 year. Other potential complications that may occur include stomach or mouth irritation near the catheter insertion sites and gastroesophageal reflux.

Open-capsule technique improves AIE
CHICAGO – A thrice-daily regimen of open-capsule budesonide has the potential to manage a rare and severe illness – adult autoimmune enteropathy (AIE) – according to Ayush Sharma, MD.
Most patients who received the treatment responded to it, with about half experiencing a complete cessation of the chronic diarrhea that is the clinical hallmark of adult autoimmune enteropathy, Dr. Sharma said at the annual Digestive Disease Week®.
“AIE is a very rare disease, with only about 50 cases reported in the literature,” said Dr. Sharma. But part of its rarity may result from misdiagnosis. AIE is frequently mistaken for severe treatment-refractory celiac disease. Both are clinically characterized by refractory diarrhea, malabsorption of nutrients, and anorexia. However, unlike celiac disease, which is caused by genetic gluten intolerance and limited to the large intestine, AIE is a pangastrointestinal disorder that also involves the pancreas and liver. On histology, the small intestine displays often complete villous atrophy. AIE also has a very specific immune marker: gut epithelial cell antibodies, which attack enterocytes and goblet cells. These cells are often completely absent as the disease progresses.
AIE has typically been treated with immunosuppressive therapy, including corticosteroids and azathioprine. Resistant cases have been treated with adalimumab, infliximab, and tacrolimus, which are moderately successful. Because it’s an autoimmune disorder, patients need long-term maintenance therapy, which exposes them to all the risks associated with these powerful medicines.
Recently, physicians at the Mayo Clinic have adopted Dr. Murray’s open-capsule budesonide regimen as an AIE treatment. It employs three daily doses of 3-mg enteric-coated budesonide capsules, which are consumed in three different ways:
- Morning dose: Open the capsule, empty the contents in applesauce, grind between the teeth, and swallow with water.
- Afternoon dose: Open the capsule, empty the contents in applesauce, and swallow without chewing.
- Evening dose: Swallow the whole capsule.
Dr. Sharma presented a retrospective analysis comparing patient characteristics and treatment response among 43 patients with treatment-refractory celiac disease (RCD) and 26 with AIE. Patients were treated at the Mayo Clinic in Rochester from 2001 to 2016.
AIE patients were younger than RCD patients (44 vs. 57 years) and, more often, male (62% vs. 28%). They were more likely to report diarrhea (100% vs. 70%), weight loss (84% vs. 69%), and fatigue (50% vs. 14%), and to be on total parenteral nutrition (35% vs. 7%).
A large proportion (69%) had tried a gluten-free diet, but none responded to it. Gut epithelial cell antibodies were often present (82% of AIE patients vs. 12.5% of RCD patients). AIE patients more often had hypoalbuminemia (64% vs. 16%). Nearly half (46%) showed complete villous atrophy, compared with 30% of those with RCD. However, they showed intraepithelial lymphocytes less often than did those with RCD (54% vs. 91%).
Patients in both the AIE and RCD cohorts were initially treated with other drugs, including azathioprine (27% and 35%, respectively) and systemic corticosteroids (96% and 14%). Only three of the AIE patients responded well to these. Additionally, about a quarter of each cohort had already taken a course of enteric-coated budesonide, but none had responded to it. All patients except the three responders were given a trial of open-capsule budesonide.
Clinical response was defined as complete cessation of diarrhea after treatment. Partial response was an improvement in stool frequency or weight gain but not complete resolution. After subtracting the numbers lost to follow-up and the patients who responded to initial therapy, clinical outcomes were available for 17 AIE patients and 37 RCD patients (about 85% of each group).
Almost half of those with AIE (8; 47%) and a majority of those with RCD (25; 68%) experienced a complete response to open-capsule budesonide. A partial response occurred in seven of those with AIE (41%) and nine of those with RCD (24%). Only two patients with AIE and three with RCD failed to respond to the regimen.
“We were very happy to see that 89% of our AIE patients responded to open-label budesonide,” Dr. Sharma said. “We need prospective clinical trials of this treatment. Open-label budesonide may be useful as an initial treatment in AIE, with the benefit of a safer therapeutic profile than systemic steroids.”
Dr. Sharma had no relevant financial disclosures.

“We were very happy to see that 89% of our AIE patients responded to open-label budesonide,” Dr. Sharma said. “We need prospective clinical trials of this treatment. Open-label budesonide may be useful as an initial treatment in AIE, with the benefit of a safer therapeutic profile than systemic steroids.”

Plecanatide improves bowel function, abdominal pain
CHICAGO – Plecanatide, a drug recently approved for chronic idiopathic constipation, bested placebo in two randomized studies evaluating its effect in irritable bowel syndrome with constipation.
Results of the identical, 12-week, phase III studies propelled plecanatide (Trulance; Synergy Pharmaceuticals) into a supplemental new drug application for adult irritable bowel syndrome–constipation predominant (IBS-C), Ronald Fogel, MD, said at the annual Digestive Disease Week®.
During the question-and-answer period, though, clinicians didn’t quite echo the corporate enthusiasm for plecanatide. Several pointed out that overall responder rates were somewhat low for both the 3-mg and 6-mg dose (study -04, 30% both doses; study -05, 21% and 24%), with a drug-placebo differential of about 12% and 7%, respectively. When questioned, Dr. Fogel didn’t have data on the number needed to treat to improve one case. But, he asserted, such response numbers are typical for drug trials in patients with functional bowel disorders and meaningful to those who did respond.
“The differences were statistically significant, and, as someone who was there for both trials, I would say they are also clinically significant,” said Dr. Fogel, founder of the Digestive Health Center of Michigan, Chesterfield. “Patients who did respond were very happy.”
The drug was also quite well-tolerated, with diarrhea as the only important treatment-related adverse event and. This occurred in less than 2% of patients, and only about 1% of either cohort discontinued the medication because of severe diarrhea.
Plecanatide, structurally, is almost identical to uroguanylin, a peptide that regulates sodium and bicarbonate secretion into the intestine but with 8 times greater binding potential to the guanylate cyclase-C receptor. Both the natural and manmade molecules promote fluid secretion into the lumen and inhibit fluid absorption. Uroguanylin is most active in an acidic environment; therefore, plecanatide exerts most of its action in the proximal small intestine.
Synergy also asserts on its website that activation of the GC-C-receptor “may lead to decreased inflammation and pain sensation in the GI tract.” Abdominal pain was not a primary outcome in the pivotal trials for plecanatide’s idiopathic constipation studies, but it was a coprimary endpoint, with stool frequency, for the IBS-C trials.
The studies enrolled a total of 2,189 patients with a diagnosis of IBS-S. They were equally randomized to placebo or plecanatide 3 mg or 6 mg, once daily. Most (75%) were women. The mean age was about 43 years. At baseline, they reported less than one complete, spontaneous bowel movement per week. They also completed an 11-point scale on abdominal symptoms of pain (mean, 6), discomfort (mean, 6.2), and bloating (mean, 6.5).
The study included a 2-week pretreatment assessment period, 12 weeks of daily therapy during which patients filled out an electronic diary of stool frequency and abdominal pain/discomfort, and a 2-week follow-up. The primary endpoint was the number of overall responders, who had to experience both a decrease of at least 30% in their weekly abdominal pain score and an increase of at least one complete, spontaneous bowel movement per week.
Both studies posted statistically significant overall responder rates, relative to placebo, in both doses.
In study -04, the final overall placebo response rate was 17.8%, compared with 30% in the plecanatide 3-mg group and 29.5% in the plecanatide 6-mg group. In study -05, the placebo responder rate was 14%, compared with 21.5% in the 3-mg group and 24% in the 6-mg group.
Dr. Fogel showed stool frequency data but not abdominal pain data. About 41% of patients taking the study drug had increased bowel movements for at least 6 weeks of treatment, compared with 31.4% of those taking placebo. This 9% absolute difference was remarked on during the question-and-answer period as a surprisingly small separation. However, Dr. Fogel said that it was clinically significant as well as statistically so, with a P value of less than 0.001.
Plecanatide worked quickly. By the end of treatment week 1, the placebo and both active groups had already significantly separated, and that separation remained significant throughout the entire treatment period. During the 2-week follow-up period, the effect of both active doses tailed off and fell to the same as placebo by the end of 2 weeks.
One of the drug’s strongest points was its low rate of treatment-related diarrhea. Any diarrhea occurred in about 4% of both dosage groups, compared to 1% of the placebo group. Severe diarrhea occurred in 1% of the 3-mg and 0.4% of the 6-mg group, compared with 0.1% of the placebo group. This caused about 1% of patients to discontinue the study medication.
The adverse event profile was notably better than that of linaclotide (Linzess; Allergan), plecanatide’s close competitor. Also a guanylate cyclase–C agonist, linaclotide provoked diarrhea in almost 20% of patients in its pivotal phase III trials. Symptoms were severe in 2%. Lincalotide’s effectiveness in promoting bowel movements was slightly higher than that of plecanatide (about 48% in the pivotal trials), with a similar placebo response rate.
Plecanatide was approved earlier this year for chronic idiopathic constipation in adults.
Synergy Pharmaceuticals sponsored the study. Dr. Fogel has no financial interest in the company or in plecanatide.

Challenges facing independent integrated gastroenterology in 2017
The practice of gastroenterology is challenging for community physicians, those employed in multi-specialty clinics or large health care systems and those in academic health centers. Unique challenges confront independent GI practices, and there are mounting regulatory, financial, and operational barriers. Election results of 2016 have thrown us into an even more confusing future. In this month’s Road Ahead column, national GI leaders summarize the major challenges facing independent practices. Each leads (or has led) large GI practices and each has extensive experience with the policies, politics, payers, and pitfalls that impact our specialty. They have written a clear and helpful article for all physicians trying to maintain their independence and patient-focused practices. I have worked in many settings from the VA, to small and then large, independent practice, within a health system and in 2 academic medical centers. There is much to treasure in every type of practice and also many challenges. Physician leaders, both old and young, need to be informed and active in shaping medical policy.
John I. Allen, MD, MBA, AGAF, Editor in Chief
Physicians practicing in independent settings report greater satisfaction with their careers compared with those employed in hospital systems. In a recent survey,1 nearly two-thirds of independent practitioners strongly agreed with the statement, “I like being a physician,” compared with approximately half of those employed by hospital systems. The rapid pace of change in care delivery is forcing all caregivers to modify how they provide care. For physicians practicing in independent settings, understanding, reacting, and adapting to these changes is especially challenging.
It is particularly difficult for physicians and practices to remain abreast and cognizant of the ever-changing rules governing how we deliver care for our patients. The Digestive Health Physicians Association was formed 2 years ago to provide an active voice specifically for independent gastroenterology (GI) practices. The mission of the Digestive Health Physicians Association is to promote and protect the high-quality and cost-efficient care provided in the integrated GI practice model.
In the past decade, meeting the goal of the Triple Aim (improving population health, improving patient experience of care, and reducing the per-capita cost of health care) has become a central tenet of our national health policy strategy, especially since the enactment of the Affordable Care Act. Achieving the goals of the Triple Aim and complying with the changes and new requirements challenges all gastroenterologists, but particularly those working in the independent practice setting, and especially those in small group practices. The Centers for Medicare and Medicaid Services (CMS) recently estimated that under the Merit-Based Incentive Payment System, payment reductions resulting from the first year of reporting in 2017 will occur in 87% of solo practices, in 70% of groups with 2 to 9 physicians, and in 60% of groups with 10 to 24 physicians.2
Preparing yourself and your practice for the changes ahead will require an understanding of the rules, an assessment of your practice’s readiness, and the creation of a plan for compliance to ensure success.
The care model has undergone major changes in the past decade. The development of regional hospital systems has resulted in increasing numbers of employed physicians. Independent gastroenterology practices also have made changes in how they provide care. Vertical integration by independent practices has been a major, positive, and continuing development. As practices have grown more sophisticated with greater areas of specialization, they are increasingly capable of providing services directly to their patients rather than outsourcing them to external providers. Beginning first with endoscopic procedures and now extending to anesthesia, pathology, infusion, and other critical services, increased integration of services across the entire continuum of care has led to improved efficiency and care coordination, benefitting patients with improved outcomes as well as lower costs to our health care system.
The benefits and successes of practice integration, unfortunately, also have made vertically integrated practices a target for regulators and policy makers. Attacks on the integrated delivery model in gastroenterology have at times been supported, if not directly initiated, by our own colleagues in the house of medicine. In this article, we describe some of the threats and challenges confronting independent GI practice.
Anesthesia services
In April 2016, the Florida Society of Anesthesiologists (FSA) made headlines by drawing attention to its role as the relator in a qui tam (whistleblower) lawsuit that it had filed against more than 50 physicians, Ambulatory Surgery Centers, and anesthesia entities. This legal action — which the FSA filed in October 2013 but remained under seal until earlier this year — alleged that the defendants perpetrated Medicare and Medicaid fraud through violations of the federal Anti-Kickback Statute and the False Claims Act. In this lawsuit, the FSA specifically targeted the company model used to provide anesthesia services. Based on publicly available documents, the case currently is in its early stages, although the FSA has made it clear that it views the lawsuit as a blueprint for attacking integrated anesthesia services.
The FSA’s qui tam action in Florida is part of a broader agenda by those who seek to undermine the integrated care model that enables gastroenterologists and other physician specialists to integrate anesthesia services into lawful care models. A website describing the Florida qui tam action hailed the American Society of Anesthesiology for having “repeatedly petitioned the Office of the Inspector General, brought the issue up with Congressional leaders and executive branch regulators, and provided information and legal resources to its members.”3 These efforts to undermine integrated, coordinated care at the federal level also have extended to the state level, in which efforts have been made in front of licensing boards and state legislatures – albeit unsuccessfully – to restrict the integration of anesthesia services.
In-Office Ancillary Services Exception
The In-Office Ancillary Services Exception (IOASE) to the federal physician self-referral statute (the Stark Law), allows physician practices to provide certain services, including diagnostic imaging and anatomic pathology, in an integrated and coordinated fashion within their respective practices when strict criteria are met.
Not surprisingly, competing providers of these services have long fought for the elimination of the IOASE. In 2013, Representative Jackie Speier (D-CA) introduced the Promoting Integrity in Medicare Act. This bill sought to eliminate those legal protections for providing those integrated medical services under the IOASE. Vigorous support for the legislation was provided by a group called the Alliance for Integrity in Medicine, a coalition of organizations including the College of American Pathologists, the American Society for Clinical Pathology, the American Clinical Laboratory Association, and the American College of Radiology. Although that bill did not even receive a vote during the last Congress, Representative Speier has re-introduced it in this current session, and continues to lobby aggressively in support of this legislation. President Obama’s budget for 2016, as the President’s budget proposal had done for the past several years, also included elimination of the IOASE provision. Extensive advocacy efforts by a broad range of specialty organizations have been instrumental to date in defeating this proposal. A study commissioned by the Digestive Health Physicians Association,4 using Medicare data, showed that GI-related anatomic pathology services actually increased more slowly in professional settings (physician offices and laboratories), at an annual rate of 1.2% from 2009 to 2013, compared with the outpatient hospital setting of 3.5% during that same period. Efforts to restrict practice integration similarly are being made at the state level. In California, legislation to eliminate the IOASE under the State’s self-referral law was introduced in 2014. Coordinated efforts by California patient- and physician-interest groups were successful in educating legislators on the value of the integrated care mode and the bill was soundly defeated.
Medicare Part B Drug Benefit
In March 2016, a new threat to integrated care in GI surfaced when the CMS released a proposed rule that would test a new Medicare Part B payment model for infused drugs including infliximab and vedolizumab. Under the proposal, the CMS would reduce the current reimbursement of 6% above average sales price (ASP) to ASP plus 2.5%, plus a flat fee of $16.85 per infusion. CMS calculations in this proposal failed to include the mandatory 2% sequestration of Medicare payments under the Budget Control Act, which means that the actual reimbursement will be less than 1% over ASP. Because many practices are unable to negotiate discounts for these drugs, unintended consequences of this proposal may disrupt care coordination efforts, resulting in movement of infusions performed in the office setting into the more costly hospital setting. Perversely, although the stated intent of this proposal was to reduce incentives for prescribing more expensive drugs, infused biologic agents are actually treatments of last choice for many inflammatory bowel disease patients.
In the absence of less-expensive alternatives, this proposed change in reimbursement likely will reduce access to effective therapy for some of our sickest patients and will not reduce costs. It is hoped that the vigorous advocacy by a coalition of more than 300 medical societies and patient-interest groups along with a majority of members of Congress may result in modifications to this proposal when the final rule is released later this year.
Stark Law
The Stark Law, commonly known as the Physician Self-Referral Law, originally was passed by Congress in 1989 and was substantially amended last in 1993. The Stark Law was enacted to address concerns of potential overuse or inappropriate use of services in a fee-for-service payment system. Health care delivery has changed dramatically since the Stark law was passed 27 years ago, but this statute has not kept pace and is incompatible with new and innovative delivery models that now mandate a shift from fee-for-service payment models to value-based care and the development of risk-sharing arrangements and bundling of services. In 2011, the CMS created a set of waivers for Accountable Care Organizations in the Medicare Shared Savings Program, but these waivers do not apply to many of the alternative payment models under development by independent physicians.
In the past year, Congress repealed the Sustainable Growth Rate formula. Both the Affordable Care Act and the Medicare Access and Children’s Health Insurance Program Reauthorization Act of 2015 were designed to move our health care system away from fee for service (volume) and toward payment for value. The current Stark Law was created to control arrangements in a fee-for-service system, but the Stark Law now obstructs the ability of physicians in independent practices to coordinate care and work as teams across specialties and with their colleagues who care for patients in other sites of service such as hospitals and academic medical centers.
Congress and CMS recently have heard from dozens of physician organizations, including all of the GI societies, about the need to modernize the Stark Law (by way of updates to the Stark statute and its corresponding regulations) to keep pace with the changes in health care delivery and to ensure successful implementation of the Medicare Access and Children’s Health Insurance Program Reauthorization Act. The changes sought include modifications to the definition of the term group practice to permit coordinated care across specialties and sites of service as well as to promote value-based compensation for all physicians.
Conclusions
To maximally amplify our voices as well our ability to effect positive change, gastroenterologists and other specialists should be actively engaged with the GI societies to help influence those changes proposed. Joining together will facilitate the adaptation by practices to change as it is mandated. The American Gastroenterological Association has long advocated for independent practices promoting optimal patient care delivery. Working cooperatively and collectively with colleagues in all GI professional organizations will enhance our ability to advance the best interests of our patients and our practices.

This legal action — which the FSA filed in October 2013 but remained under seal until earlier this year — alleged that the defendants perpetrated Medicare and Medicaid fraud through violations of the federal Anti-Kickback Statute and the False Claims Act. In this lawsuit, the FSA specifically targeted the company model used to provide anesthesia services. Based on publicly available documents, the case currently is in its early stages, although the FSA has made it clear that it views the lawsuit as a blueprint for attacking integrated anesthesia services.
The FSA’s qui tam action in Florida is part of a broader agenda by those who seek to undermine the integrated care model that enables gastroenterologists and other physician specialists to integrate anesthesia services into lawful care models. A website describing the Florida qui tam action hailed the American Society of Anesthesiology for having “repeatedly petitioned the Office of the Inspector General, brought the issue up with Congressional leaders and executive branch regulators, and provided information and legal resources to its members.”3 These efforts to undermine integrated, coordinated care at the federal level also have extended to the state level, in which efforts have been made in front of licensing boards and state legislatures – albeit unsuccessfully – to restrict the integration of anesthesia services.
In-Office Ancillary Services Exception
The In-Office Ancillary Services Exception (IOASE) to the federal physician self-referral statute (the Stark Law), allows physician practices to provide certain services, including diagnostic imaging and anatomic pathology, in an integrated and coordinated fashion within their respective practices when strict criteria are met.
Not surprisingly, competing providers of these services have long fought for the elimination of the IOASE. In 2013, Representative Jackie Speier (D-CA) introduced the Promoting Integrity in Medicare Act. This bill sought to eliminate those legal protections for providing those integrated medical services under the IOASE. Vigorous support for the legislation was provided by a group called the Alliance for Integrity in Medicine, a coalition of organizations including the College of American Pathologists, the American Society for Clinical Pathology, the American Clinical Laboratory Association, and the American College of Radiology. Although that bill did not even receive a vote during the last Congress, Representative Speier has re-introduced it in this current session, and continues to lobby aggressively in support of this legislation. President Obama’s budget for 2016, as the President’s budget proposal had done for the past several years, also included elimination of the IOASE provision. Extensive advocacy efforts by a broad range of specialty organizations have been instrumental to date in defeating this proposal. A study commissioned by the Digestive Health Physicians Association,4 using Medicare data, showed that GI-related anatomic pathology services actually increased more slowly in professional settings (physician offices and laboratories), at an annual rate of 1.2% from 2009 to 2013, compared with the outpatient hospital setting of 3.5% during that same period. Efforts to restrict practice integration similarly are being made at the state level. In California, legislation to eliminate the IOASE under the State’s self-referral law was introduced in 2014. Coordinated efforts by California patient- and physician-interest groups were successful in educating legislators on the value of the integrated care mode and the bill was soundly defeated.
Medicare Part B Drug Benefit
In March 2016, a new threat to integrated care in GI surfaced when the CMS released a proposed rule that would test a new Medicare Part B payment model for infused drugs including infliximab and vedolizumab. Under the proposal, the CMS would reduce the current reimbursement of 6% above average sales price (ASP) to ASP plus 2.5%, plus a flat fee of $16.85 per infusion. CMS calculations in this proposal failed to include the mandatory 2% sequestration of Medicare payments under the Budget Control Act, which means that the actual reimbursement will be less than 1% over ASP. Because many practices are unable to negotiate discounts for these drugs, unintended consequences of this proposal may disrupt care coordination efforts, resulting in movement of infusions performed in the office setting into the more costly hospital setting. Perversely, although the stated intent of this proposal was to reduce incentives for prescribing more expensive drugs, infused biologic agents are actually treatments of last choice for many inflammatory bowel disease patients.
In the absence of less-expensive alternatives, this proposed change in reimbursement likely will reduce access to effective therapy for some of our sickest patients and will not reduce costs. It is hoped that the vigorous advocacy by a coalition of more than 300 medical societies and patient-interest groups along with a majority of members of Congress may result in modifications to this proposal when the final rule is released later this year.
Stark Law
The Stark Law, commonly known as the Physician Self-Referral Law, originally was passed by Congress in 1989 and was substantially amended last in 1993. The Stark Law was enacted to address concerns of potential overuse or inappropriate use of services in a fee-for-service payment system. Health care delivery has changed dramatically since the Stark law was passed 27 years ago, but this statute has not kept pace and is incompatible with new and innovative delivery models that now mandate a shift from fee-for-service payment models to value-based care and the development of risk-sharing arrangements and bundling of services. In 2011, the CMS created a set of waivers for Accountable Care Organizations in the Medicare Shared Savings Program, but these waivers do not apply to many of the alternative payment models under development by independent physicians.
In the past year, Congress repealed the Sustainable Growth Rate formula. Both the Affordable Care Act and the Medicare Access and Children’s Health Insurance Program Reauthorization Act of 2015 were designed to move our health care system away from fee for service (volume) and toward payment for value. The current Stark Law was created to control arrangements in a fee-for-service system, but the Stark Law now obstructs the ability of physicians in independent practices to coordinate care and work as teams across specialties and with their colleagues who care for patients in other sites of service such as hospitals and academic medical centers.
Congress and CMS recently have heard from dozens of physician organizations, including all of the GI societies, about the need to modernize the Stark Law (by way of updates to the Stark statute and its corresponding regulations) to keep pace with the changes in health care delivery and to ensure successful implementation of the Medicare Access and Children’s Health Insurance Program Reauthorization Act. The changes sought include modifications to the definition of the term group practice to permit coordinated care across specialties and sites of service as well as to promote value-based compensation for all physicians.
Conclusions
To maximally amplify our voices as well our ability to effect positive change, gastroenterologists and other specialists should be actively engaged with the GI societies to help influence those changes proposed. Joining together will facilitate the adaptation by practices to change as it is mandated. The American Gastroenterological Association has long advocated for independent practices promoting optimal patient care delivery. Working cooperatively and collectively with colleagues in all GI professional organizations will enhance our ability to advance the best interests of our patients and our practices.

The practice of gastroenterology is challenging for community physicians, those employed in multi-specialty clinics or large health care systems and those in academic health centers. Unique challenges confront independent GI practices, and there are mounting regulatory, financial, and operational barriers. Election results of 2016 have thrown us into an even more confusing future. In this month’s Road Ahead column, national GI leaders summarize the major challenges facing independent practices. Each leads (or has led) large GI practices and each has extensive experience with the policies, politics, payers, and pitfalls that impact our specialty. They have written a clear and helpful article for all physicians trying to maintain their independence and patient-focused practices. I have worked in many settings from the VA, to small and then large, independent practice, within a health system and in 2 academic medical centers. There is much to treasure in every type of practice and also many challenges. Physician leaders, both old and young, need to be informed and active in shaping medical policy.

Physicians practicing in independent settings report greater satisfaction with their careers compared with those employed in hospital systems. In a recent survey,1 nearly two-thirds of independent practitioners strongly agreed with the statement, “I like being a physician,” compared with approximately half of those employed by hospital systems. The rapid pace of change in care delivery is forcing all caregivers to modify how they provide care. For physicians practicing in independent settings, understanding, reacting, and adapting to these changes is especially challenging.
It is particularly difficult for physicians and practices to remain abreast and cognizant of the ever-changing rules governing how we deliver care for our patients. The Digestive Health Physicians Association was formed 2 years ago to provide an active voice specifically for independent gastroenterology (GI) practices. The mission of the Digestive Health Physicians Association is to promote and protect the high-quality and cost-efficient care provided in the integrated GI practice model.
In the past decade, meeting the goal of the Triple Aim (improving population health, improving patient experience of care, and reducing the per-capita cost of health care) has become a central tenet of our national health policy strategy, especially since the enactment of the Affordable Care Act. Achieving the goals of the Triple Aim and complying with the changes and new requirements challenges all gastroenterologists, but particularly those working in the independent practice setting, and especially those in small group practices. The Centers for Medicare and Medicaid Services (CMS) recently estimated that under the Merit-Based Incentive Payment System, payment reductions resulting from the first year of reporting in 2017 will occur in 87% of solo practices, in 70% of groups with 2 to 9 physicians, and in 60% of groups with 10 to 24 physicians.2
Preparing yourself and your practice for the changes ahead will require an understanding of the rules, an assessment of your practice’s readiness, and the creation of a plan for compliance to ensure success.
The care model has undergone major changes in the past decade. The development of regional hospital systems has resulted in increasing numbers of employed physicians. Independent gastroenterology practices also have made changes in how they provide care. Vertical integration by independent practices has been a major, positive, and continuing development. As practices have grown more sophisticated with greater areas of specialization, they are increasingly capable of providing services directly to their patients rather than outsourcing them to external providers. Beginning first with endoscopic procedures and now extending to anesthesia, pathology, infusion, and other critical services, increased integration of services across the entire continuum of care has led to improved efficiency and care coordination, benefitting patients with improved outcomes as well as lower costs to our health care system.
The benefits and successes of practice integration, unfortunately, also have made vertically integrated practices a target for regulators and policy makers. Attacks on the integrated delivery model in gastroenterology have at times been supported, if not directly initiated, by our own colleagues in the house of medicine. In this article, we describe some of the threats and challenges confronting independent GI practice.

FDA approves pembrolizumab for advanced urothelial carcinoma
The Food and Drug Administration has granted regular approval to pembrolizumab (Keytruda) for patients with locally advanced or metastatic urothelial carcinoma who have disease progression during or following platinum-containing chemotherapy or within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy.
Accelerated approval was granted for patients with locally advanced or metastatic urothelial carcinoma who are not eligible for cisplatin-containing chemotherapy.
Approval of pembrolizumab for the second-line indication was based on an improvement in overall survival and objective response rate (ORR) in the KEYNOTE-045 trial. Median overall survival was 10.3 months for patients randomized to receive pembrolizumab (n = 270) every 3 weeks, compared with 7.4 months for patients randomized to receive the investigator’s choice of a chemotherapy regimen (paclitaxel [n = 84], docetaxel [n = 84], or vinflunine [n = 87]) every 3 weeks (hazard ratio, 0.73; 95% confidence interval: 0.59-0.91, P =.004). ORR was 21% for pembrolizumab and 11% for chemotherapy (P = .002). All patients had locally advanced or metastatic urothelial carcinoma with disease progression on or after platinum-containing chemotherapy. No statistically significant difference in progression-free survival between the two arms was observed, the FDA said in a statement.
The accelerated approval for the first-line indication was based on an ORR of 28.6% (95% CI, 24-34) in KEYNOTE-052, a single-arm, open-label trial in 370 patients with locally advanced or metastatic urothelial carcinoma who were deemed not eligible for cisplatin-containing chemotherapy. The median response duration was not reached (range, 1.4+-17.8+ months).
The most common adverse reactions reported for those receiving pembrolizumab in either of the two trials included fatigue, musculoskeletal pain, pruritus, decreased appetite, nausea, diarrhea, constipation, and rash. Discontinuation of pembrolizumab occurred in 8% of patients in KEYNOTE-045 and in 11% in KEYNOTE-052. Serious adverse reactions occurred in approximately 40% of pembrolizumab-treated patients, the FDA said.
The recommended pembrolizumab dose and schedule for the treatment of urothelial carcinoma is 200 mg as an intravenous infusion over 30 minutes every 3 weeks. Full prescribing information is available the FDA website.

New heart failure guidelines prioritize prevention
The latest update to U.S. guidelines for heart failure management, released at the end of April , puts unprecedented emphasis on heart failure prevention and also shines a brighter light on patients at risk for developing heart failure – people with hypertension, diabetes, or coronary artery disease.
“We have embraced the fact that heart failure can be prevented and that the progression of heart failure can be interrupted, and we articulated how we can use biomarkers to screen patients with asymptomatic left ventricular dysfunction,” said Clyde W. Yancy, MD, chair of the writing group that issued the 2017 focused update to the heart failure management guidelines on behalf of the American College of Cardiology, the American Heart Association, and the Heart Failure Society of America. (Circulation. 2017 Apr 28. doi: 10.1161/CIR.0000000000000509).
This means that, for the first time, these guidelines focus on stage A heart failure patients, those without symptoms or detectable left ventricular dysfunction but at risk for heart failure, a heart failure subgroup that was ignored in the past. Prevention is most immediate for stage A patients. The new guidelines cite the stage A definition from the 2009 guidelines: patients with “risk factors that clearly predispose toward the development of heart failure. For example, patients with coronary artery disease, hypertension, or diabetes mellitus who do not yet demonstrate impaired left ventricular function.”
The number of patients with coronary artery disease, hypertension, or diabetes is pretty large. The new heart failure guidelines apply to many people.
“The mindset [on heart failure] has been on treatment, not prevention. There is far more focus [in the new guidelines] on prevention than ever before,” commented Javed Butler, MD, professor and chief of cardiology at Stony Brook (N.Y.) University and a member of the guideline writing panel.
“One reason why heart failure prevention has not been a focus was because people thought that, if you prevented coronary artery disease, you prevented heart failure. What we’ve learned is that a lot of heart failure is not ischemic and not from overt coronary disease, especially age-related HFpEF [heart failure with preserved ejection fraction]. Hopefully, these guidelines will spur more interest in prevention and risk factor control,” Dr. Butler said in an interview.
It starts with blood pressure
The guidelines contain an entirely new section devoted to blood pressure, and, while part of the section deals with a target blood pressure for symptomatic (stage C) heart failure patients (a goal systolic pressure of less than 130 mm Hg for patients with either a preserved or reduced ejection fraction), the first entry is a target blood pressure of less than 130/80 mm Hg for all stage A heart failure patients.
Because stage A is defined to include any adult with hypertension, the new heart failure guidelines set a new blood pressure treatment goal for all U.S. adults with hypertension at a time when the long-awaited revision to U.S. hypertension management guidelines from the ACC and AHA are still pending. Until the new hypertension guidelines come out – they’re expected later this year – the blood pressure target set in the heart failure guidelines will have to suffice.
Indeed, the less than 130/80-mm Hg target for on-treatment blood pressure set for heart failure prevention in the new guidelines was picked to “harmonize” with the guidelines that the ACC and AHA hypertension panel will soon release, Dr. Jessup said in an interview.
The main evidence for this target, lower than in most prior U.S. hypertension guidelines, comes from SPRINT (Systolic Blood Pressure Intervention Trial) (N Engl J Med. 2015 Nov 26;373[22]:2103-16). In that trial, the goal blood pressure that linked with the best outcomes was less than 120/80 mm Hg, although the average achieved systolic blood pressure was above that goal with a mean systolic pressure of 121.5 mm Hg. One reason for setting a higher goal systolic pressure for practice was that analyses have shown that blood pressure measurement in SPRINT did not perform like conventional measurements in routine practice. SPRINT patients appeared to have lower measured pressures than they would have recorded had they been measured by more conventional means (Hypertension. 2017 January;69[1]:15-9).
“The way that blood pressures were measured in SPRINT, a pressure of 120/80 mm Hg in the trial was akin to a pressure of 130/80 mm Hg in an office,” Dr. Yancy, chief of cardiology at Northwestern University, Chicago, said in an interview. “To avoid dangerous hypotension and to approximate SPRINT, an office pressure of less than 130 mm Hg is a reasonable number.”
New role for BNP screening
Stage A patients are more than just the target for more aggressive hypertension control. They are now also potential candidates for screening for an elevated blood level of brain natriuretic peptide (BNP) or N-terminal (NT)–proBNP. The guidelines panel makes this a level IIa recommendation, saying that a screening BNP test in patients at risk for developing heart failure can be useful if followed by team-based care and optimized guideline directed medical therapy.
This guideline follows the lead of two successful controlled trials that focused more aggressive preventive treatments on stage A patients with an elevated level of BNP or NT-proBNP – the STOP-HF (JAMA. 2013 July 3;310[1]:66-74) and PONTIAC (J Am Coll Cardiol. 2013 Oct;62[15]:1365-72) trials. The target population for some type of BNP screening are patients with cardiovascular disease, vascular disease, diabetes, obesity, or hypertension, Dr. Yancy said. “It was evident in STOP-HF that, if you screened and intervened, you could make a difference” in the development of heart failure.
The STOP-HF intervention included “optimal risk factor management” and “coaching by a specialist nurse who emphasized individual risk status and the importance of adherence to medication and healthy lifestyle behaviors.”
The guidelines aren’t clear on which patients at risk for developing heart failure, stage A patients, should get screened with BNP or NT-proBNP. Dr. Jessup said that it’s for patients in whom a positive result would trigger more aggressive management.
Getting a BNP on a suspect patient can raise a red flag to the patient, as well as to the physician, that more intervention is needed. “It’s easy for a physician to ignore a high-risk patient who looks okay and feels okay.” A BNP or NT-proBNP test can pick out the patients who shouldn’t be ignored, Dr. Januzzi said.
HFpEF treatment now possible
Another groundbreaking change in the guidelines is inclusion, for the first time, of a medical treatment specific for HFpEF. The aldosterone receptor antagonists (ARAs) spironolactone and eplerenone received a class IIb recommendation: An ARA might be considered to decrease hospitalizations in patients with HFpEF with an ejection fraction of at least 45%, an elevated BNP or recent hospitalization, and good renal function and potassium level.
The “might be considered” recommendation is guarded but understandable given that the evidence comes from the somewhat controversial, post-hoc analysis of data from the pivotal TOPCAT trial (N Engl J Med. 2014 Apr 10;370[15]:1383-92) that focused on just the roughly half of patients seen at centers in North or South America (Circulation. 2015 Jan 6;131[1]:34-42).
“It would be irresponsible to overlook the potential that [ARAs] may help patients who looks like the ones enrolled in TOPCAT in the Americas,” said Dr. Yancy. “We blended evidence and pragmatism and said that the field needs this” treatment. He said that an ARA was a reasonable option for HFpEF patients with symptoms of heart failure and a positive biomarker test result.
Dr. Butler largely agreed. ARA treatment is for HFpEF patients with symptomatic heart failure and either a history of hospitalization or a high BNP level, he said.
“I was surprised by how strongly the committee felt there was a reasonable signal of help from ARAs in HFpEF,” said Dr. Jessup. “I believe in them too,” she added.
Dr. Jessup suggested targeting an ARA to a HFpEF patient with some hypertension, some volume problem, some peripheral edema, and a lot of breathlessness but with no underlying ischemia. “I use an ARA on these patients pretty quickly,” Dr. Jessup said. It’s best to start with a low dosage and see how the patient responds. “The best responders have a really stiff heart” and are usually not the more elderly HFpEF patients. ARA treatment also provides more steady volume control, superior to furosemide, she said.
Yet more additions
The revised guidelines contain even more changes. “We say that checking for anemia is important and how iron is an intervention that might make a difference,” said Dr. Jessup. Also, primary care physicians and cardiologists “should look for obstructive sleep apnea” in heart failure patients for whom “intervention with weight loss might help,” she said.
Another feature is the focus on tailored treatment, with many treatment elements that need customizing to each different type of heart failure patient. “Not every drug needs to be given to every patient,” Dr. Yancy warned.
The specifics of how to orchestrate all the guidelines into a coherent management plan may become clearer later this year, when the ACC/AHA group will release a follow-up “Heart Failure Pathways” document, aimed at bridging the gap between guidelines and actual clinical practice, Dr. Yancy said. “We want more value from writing the guidelines. The biggest obstacle is how to implement them,” and that’s what the pathways follow-up will address.
“The biggest challenge the societies have is how to motivate physicians and nurses to more aggressively treat heart failure,” said Dr. Butler.
Dr. Yancy and Dr. Jessup had no disclosures. Dr. Butler has been a consultant to 11 companies.

The latest update to U.S. guidelines for heart failure management, released at the end of April , puts unprecedented emphasis on heart failure prevention and also shines a brighter light on patients at risk for developing heart failure – people with hypertension, diabetes, or coronary artery disease.
“We have embraced the fact that heart failure can be prevented and that the progression of heart failure can be interrupted, and we articulated how we can use biomarkers to screen patients with asymptomatic left ventricular dysfunction,” said Clyde W. Yancy, MD, chair of the writing group that issued the 2017 focused update to the heart failure management guidelines on behalf of the American College of Cardiology, the American Heart Association, and the Heart Failure Society of America. (Circulation. 2017 Apr 28. doi: 10.1161/CIR.0000000000000509).
This means that, for the first time, these guidelines focus on stage A heart failure patients, those without symptoms or detectable left ventricular dysfunction but at risk for heart failure, a heart failure subgroup that was ignored in the past. Prevention is most immediate for stage A patients. The new guidelines cite the stage A definition from the 2009 guidelines: patients with “risk factors that clearly predispose toward the development of heart failure. For example, patients with coronary artery disease, hypertension, or diabetes mellitus who do not yet demonstrate impaired left ventricular function.”
The number of patients with coronary artery disease, hypertension, or diabetes is pretty large. The new heart failure guidelines apply to many people.
“The mindset [on heart failure] has been on treatment, not prevention. There is far more focus [in the new guidelines] on prevention than ever before,” commented Javed Butler, MD, professor and chief of cardiology at Stony Brook (N.Y.) University and a member of the guideline writing panel.
“One reason why heart failure prevention has not been a focus was because people thought that, if you prevented coronary artery disease, you prevented heart failure. What we’ve learned is that a lot of heart failure is not ischemic and not from overt coronary disease, especially age-related HFpEF [heart failure with preserved ejection fraction]. Hopefully, these guidelines will spur more interest in prevention and risk factor control,” Dr. Butler said in an interview.
It starts with blood pressure
The guidelines contain an entirely new section devoted to blood pressure, and, while part of the section deals with a target blood pressure for symptomatic (stage C) heart failure patients (a goal systolic pressure of less than 130 mm Hg for patients with either a preserved or reduced ejection fraction), the first entry is a target blood pressure of less than 130/80 mm Hg for all stage A heart failure patients.
Because stage A is defined to include any adult with hypertension, the new heart failure guidelines set a new blood pressure treatment goal for all U.S. adults with hypertension at a time when the long-awaited revision to U.S. hypertension management guidelines from the ACC and AHA are still pending. Until the new hypertension guidelines come out – they’re expected later this year – the blood pressure target set in the heart failure guidelines will have to suffice.
Indeed, the less than 130/80-mm Hg target for on-treatment blood pressure set for heart failure prevention in the new guidelines was picked to “harmonize” with the guidelines that the ACC and AHA hypertension panel will soon release, Dr. Jessup said in an interview.
The main evidence for this target, lower than in most prior U.S. hypertension guidelines, comes from SPRINT (Systolic Blood Pressure Intervention Trial) (N Engl J Med. 2015 Nov 26;373[22]:2103-16). In that trial, the goal blood pressure that linked with the best outcomes was less than 120/80 mm Hg, although the average achieved systolic blood pressure was above that goal with a mean systolic pressure of 121.5 mm Hg. One reason for setting a higher goal systolic pressure for practice was that analyses have shown that blood pressure measurement in SPRINT did not perform like conventional measurements in routine practice. SPRINT patients appeared to have lower measured pressures than they would have recorded had they been measured by more conventional means (Hypertension. 2017 January;69[1]:15-9).
“The way that blood pressures were measured in SPRINT, a pressure of 120/80 mm Hg in the trial was akin to a pressure of 130/80 mm Hg in an office,” Dr. Yancy, chief of cardiology at Northwestern University, Chicago, said in an interview. “To avoid dangerous hypotension and to approximate SPRINT, an office pressure of less than 130 mm Hg is a reasonable number.”
New role for BNP screening
Stage A patients are more than just the target for more aggressive hypertension control. They are now also potential candidates for screening for an elevated blood level of brain natriuretic peptide (BNP) or N-terminal (NT)–proBNP. The guidelines panel makes this a level IIa recommendation, saying that a screening BNP test in patients at risk for developing heart failure can be useful if followed by team-based care and optimized guideline directed medical therapy.
This guideline follows the lead of two successful controlled trials that focused more aggressive preventive treatments on stage A patients with an elevated level of BNP or NT-proBNP – the STOP-HF (JAMA. 2013 July 3;310[1]:66-74) and PONTIAC (J Am Coll Cardiol. 2013 Oct;62[15]:1365-72) trials. The target population for some type of BNP screening are patients with cardiovascular disease, vascular disease, diabetes, obesity, or hypertension, Dr. Yancy said. “It was evident in STOP-HF that, if you screened and intervened, you could make a difference” in the development of heart failure.
The STOP-HF intervention included “optimal risk factor management” and “coaching by a specialist nurse who emphasized individual risk status and the importance of adherence to medication and healthy lifestyle behaviors.”
The guidelines aren’t clear on which patients at risk for developing heart failure, stage A patients, should get screened with BNP or NT-proBNP. Dr. Jessup said that it’s for patients in whom a positive result would trigger more aggressive management.
Getting a BNP on a suspect patient can raise a red flag to the patient, as well as to the physician, that more intervention is needed. “It’s easy for a physician to ignore a high-risk patient who looks okay and feels okay.” A BNP or NT-proBNP test can pick out the patients who shouldn’t be ignored, Dr. Januzzi said.
HFpEF treatment now possible
Another groundbreaking change in the guidelines is inclusion, for the first time, of a medical treatment specific for HFpEF. The aldosterone receptor antagonists (ARAs) spironolactone and eplerenone received a class IIb recommendation: An ARA might be considered to decrease hospitalizations in patients with HFpEF with an ejection fraction of at least 45%, an elevated BNP or recent hospitalization, and good renal function and potassium level.
The “might be considered” recommendation is guarded but understandable given that the evidence comes from the somewhat controversial, post-hoc analysis of data from the pivotal TOPCAT trial (N Engl J Med. 2014 Apr 10;370[15]:1383-92) that focused on just the roughly half of patients seen at centers in North or South America (Circulation. 2015 Jan 6;131[1]:34-42).

Study links photosensitizing antihypertensives to SCC
PORTLAND, ORE. – Patients prescribed photosensitizing antihypertensive drugs had a 16% increase in risk of cutaneous squamous cell carcinoma (cSCC) in a large retrospective cohort study.
These drugs include alpha-2 receptor agonists and loop diuretics, potassium-sparing diuretics, thiazide diuretics, and combination diuretics, Katherine Levandoski said in an oral presentation at the annual meeting of the Society for Investigative Dermatology.
Furthermore, taking antihypertensive drugs of unknown photosensitizing potential conferred a 10% increase in risk of cSCC in the study, she added. Such medications include angiotensin–converting enzyme inhibitors, calcium channel blockers, and vasodilators, she said.
More than 50 million Americans take antihypertensive drugs, many of which are photosensitizing, noted Ms. Levandoski, a research assistant in the Patient Oriented Research on the Epidemiology of Skin Diseases Unit in the department of dermatology, Massachusetts General Hospital, and the department of population medicine, Harvard University, Boston. However, few studies have explored the oncogenic effects of exposure to these drugs, and those that have done so were subject to confounding, small sample sizes, missing data, lack of pathologic verification, and reliance on self-reported medication history, she added.
To help fill this knowledge gap, she and her associates studied 28,357 non-Hispanic whites diagnosed with hypertension and treated at Kaiser Permanente Northern California between 1997 and 2012. They limited the cohort to non-Hispanic whites because they represent the group with most cases of cSCC.
During follow-up, 3,010 patients were diagnosed with new-onset, pathologically verified cSCC, Ms. Levandoski said. Compared with nonusers of antihypertensives, users of photosensitizing antihypertensives had about a 16% increase in the rate of cSCC (hazard ratio, 1.16; 95% confidence interval, 1.06-1.27), even after accounting for age, sex, smoking, comorbidities, health care utilization, skin cancer history, length of health plan membership, and prior exposure to photosensitizing medications.
Strikingly, patients who used antihypertensives of unknown photosensitizing effect had a 10% increase in risk of incident cSCC (RR, 1.10; 95% CI, 1.02-1.19). Some antihypertensive drugs that are classified as unknown photosensitizers “may actually have photosensitizing properties,” Ms. Levandoski commented. Patients taking antihypertensives of known or unknown photosensitizing potential “should be educated on safe sun practices and may benefit from closer screening for cutaneous squamous cell carcinoma,” she added.
The risk of cSCC was not increased among users of nonphotosensitizing antihypertensives (HR, 0.99; 95% CI, 0.91-1.07), including alpha-blockers, beta-blockers, central agonists, and angiotensin receptor blockers, Ms. Levandoski reported.
Patients in the study cohort averaged aged 60 years (standard deviation, 10.6 years), and 56% were female. In all, 1,530 had never been prescribed antihypertensives, while about 17,000-19,000 had been prescribed unknown, known, or nonphotosensitizing antihypertensives.
The work was funded by the National Institutes of Health, a travel award from the Society for Investigative Dermatology, and a Massachusetts General Hospital Medical Student Award. Ms. Levandoski had no conflicts of interest.

Pembrolizumab shows some activity against advanced endometrial cancer
In some women with heavily pretreated locally advanced or metastatic endometrial cancers, treatment with the immune checkpoint inhibitor pembrolizumab (Keytruda) produced partial, durable responses, investigators reported.
The women were participants in the KEYNOTE-028 trial, a multicohort, open-label phase Ib basket trial of patients with advanced solid tumors positive for programmed death ligand 1 (PD-L1). Of 24 women with PD-L1-positive endometrial tumors, 3 (13%) had confirmed partial responses, and 2 of these patients remained on therapy with a continued response at the time of data cutoff, reported Patrick A. Ott, MD, PhD, of Dana-Farber Cancer Institute, Boston, and his colleagues.
“[T]he results from the KEYNOTE-028 trial presented herein indicate that pembrolizumab shows promise as a treatment for advanced endometrial cancer, a disease for which current treatment options are limited,” they wrote (J Clin Oncol. 2017 May 10; doi: 10.1200/JCO.2017.72.5952).
Patients with advanced endometrial cancer have a poor prognosis, with 5-year survival rates below 50% for patients with lymph node metastases, and less than 20% for those with distant metastases or disease that has spread to the peritoneum, the investigators noted.
“Treatment options for patients presenting with advanced disease are limited, with no consensus on a standard regimen. Similarly, no optimal therapy for patients who experience progression during first-line therapy has been identified, with second-line chemotherapeutic options producing only modest activity,” they wrote.
PD-L1 was shown to be expressed on 83% of primary endometrial tumors and 100% of metastatic endometrial cancers in one study (Cancer Immunol Immunother. 2014;63[6]:545-57), suggesting that could be a viable target in this difficult-to-treat disease, noted Dr. Ott and his colleagues.
In their study, 24 women with locally advanced or metastatic PD-L1–positive endometrial cancer who had experienced progression after standard therapy were treated with pembrolizumab 10 mg/kg every 2 weeks for up to 24 months or until disease progression or unacceptable toxicity. As noted, 3 of the 24 patients met the primary efficacy endpoint of objective response rate by Response Evaluation Criteria in Solid Tumors (RECIST; version 1.1) with a partial response, with the median duration of response (a secondary endpoint) not reached at the time of data cutoff on Feb. 17, 2016.
Three other patients (13%) had stable disease, with a median duration of 24.6 weeks.
Safety, also a secondary endpoint, was comparable to that seen in other studies with pembrolizumab. Four patients had grade 3 treatment-related adverse events (AEs). There were no grade 4 AEs of any kind, no immune-mediated AEs of any grade, and no treatment-related deaths.
One of the patients who had a partial response was found through genomic profiling to have a polymerase E, or POLE mutation, and this patient had a rapid improvement after starting on pembrolizumab, with the response lasting longer than 14 months.
“These exceptional results support the theory that the presence of POLE mutations may aid in identifying patients for whom pembrolizumab may be particularly effective, a concept that should be investigated further,” wrote Dr. Ott and his colleagues.
Merck Sharp & Dohme sponsored the study. Dr. Ott and multiple coauthors disclosed institution research funding, honoraria, consulting, or advising with the company, and three are Merck employees..
In some women with heavily pretreated locally advanced or metastatic endometrial cancers, treatment with the immune checkpoint inhibitor pembrolizumab (Keytruda) produced partial, durable responses, investigators reported.
The women were participants in the KEYNOTE-028 trial, a multicohort, open-label phase Ib basket trial of patients with advanced solid tumors positive for programmed death ligand 1 (PD-L1). Of 24 women with PD-L1-positive endometrial tumors, 3 (13%) had confirmed partial responses, and 2 of these patients remained on therapy with a continued response at the time of data cutoff, reported Patrick A.
