Screening and Treating Hepatitis C in the VA: Achieving Excellence Using Lean and System Redesign
Hepatitis C virus (HCV) infection is a major public health problem in the US. Following the 2010 report of the Institute of Medicine/National Academies of Sciences, Engineering, and Medicine (NASEM) on hepatitis and liver cancer, the US Department of Health and Human Services (HHS) released the first National Viral Hepatitis Action Plan in 2011 with subsequent action plan updates for 2014-2016 and 2017-2020.1-3 A NASEM phase 2 report and the 2017-2020 HHS action plan outline a national strategy to prevent new viral hepatitis infections; reduce deaths and improve the health of people living with viral hepatitis; reduce viral hepatitis health disparities; and coordinate, monitor, and report on implementation of viral hepatitis activities.3,4 The Department of Veterans Affairs (VA) is the single largest HCV care provider in the US with about 165,000 veterans in care diagnosed with HCV in the beginning of 2014 and is a national leader in the testing and treatment of HCV.5,6
The VA’s recommendations for screening for HCV infection are in alignment with the United States Preventive Services Task Force (USPSTF) and Centers for Disease Control and Prevention (CDC) recommendations to test all veterans born between 1945 and 1965 and anyone with risk factors such as injection drug use.7-9 As of January 1, 2018, the VA had screened more than 80% of veterans in care within this highest risk birth cohort. As of January 1, 2018, more than 100,000 veterans in VA care have initiated treatment for HCV with direct-acting antivirals (DAAs) (Figure 1).
Several critical factors contributed to the VA success with HCV testing and treatment, including congressional appropriation of funding from fiscal year (FY) 2016 through FY 2018, unrestricted access to interferon-free DAA HCV treatments, and dedicated resources from the VA National Viral Hepatitis Program within the HIV, Hepatitis, and Related Conditions Programs (HHRC) in the Office of Specialty Care Services.5 In 2014, HHRC created and supported the Hepatitis Innovation Team (HIT) Collaborative, a VA process improvement initiative enabling
Veterans Integrated Service Network (VISN) -based, multidisciplinary teams to increase veterans’ access to HCV testing and treatment.
As the VA makes consistent progress toward eliminating HCV in veterans in VA care, it has become clear that achieving a cure is only a starting point in improving HCV care. Many patients with HCV infection also have advanced liver disease (ALD), or cirrhosis, which is a condition of permanent liver fibrosis that remains after the patient has been cured of HCV infection. In addition to hepatitis C, ALD also can be caused by excessive alcohol use, hepatitis B virus (HBV) infection, nonalcoholic fatty liver diseases, and several other inherited diseases. Advanced liver disease affects more than 80,000 veterans in VA care, and the HIT infrastructure provides an excellent framework to better understand and address facility-level and systemwide challenges in diagnosing, caring for, and treating veterans with ALD across the Veterans Health Administration (VHA) system.
This report will describe the elements that contributed to the success of the HIT Collaborative in redesigning care for patients affected by HCV in the VA and how these elements can be applied to improve the system of care for VHA ALD care.
Hepatitis Innovation Teams Collaborative Leadership
After the US Food and Drug Administration (FDA) approved new DAA medications to treat HCV, the VA recognized the need to mobilize the health care system quickly and allocate resources for these new, minimally toxic, and highly effective medications. Early in 2014, HHRC established the National Hepatitis C Resource Center (NHCRC), a successor program to the 4 regional hepatitis C resource centers that had addressed HCV care across the system.10 The NHCRC was charged with developing an operational strategy for VA to respond rapidly to the availability of DAAs. In collaboration with representatives from the Office of Strategic Integration | Veterans Engineering Resource Center (OSI|VERC), the NHCRC formed the HIT Collaborative Leadership Team (CLT).
The HIT CLT is responsible for executing the HIT Collaborative and uses a Lean process improvement framework focused on eliminating waste and maximizing value. Members of the CLT with expertise in facilitation, Lean process improvement, leadership, clinical knowledge, and population health management act as coaches for the VISN HITs. The CLT works to build and support the VISN HITs, identify opportunities for individual teams to improve and assist in finding the right local mix of “players” to be successful. The HIT CLT ensures all teams are functioning and working toward achieving their goals. The CLT obtains data from VA national databases, which are provided to the VISN HITs to inform and encourage continuous improvement of their strategies. Annual VA-wide aspirational goals are developed and disseminated to encourage a unified mission.
Catchment areas for each VISN include between 6 and 10 medical centers as well as outpatient and ambulatory care centers. Multidisciplinary HITs are composed of physicians, nurses, pharmacists, nurse practitioners, physician assistants, social workers, mental health and substance use providers, peer support specialists, administrators, information technology experts, and systems redesign professionals from medical centers within each VISN. Teams develop strong relationships across medical centers, implement context-specific strategies applicable to rural
and urban centers, and share expertise. In addition to intra-VISN process improvement, HITs collaborate monthly across VISNs via a virtual platform. They share strong practices, seek advice from one another, and compare outcomes on an established set of goals.
The HITs use process improvement tools to systematically assess the current steps involved in care. At the close of each year, the HITs analyze the current state of operations and set goals to improve over the following year guided by a target state map. Seed funding is provided to every VISN HIT annually to launch change initiatives. Many VISN HITs use these funds to support a VISN HIT coordinator, and HITs also use this financial support to conduct 2- to 3-day process improvement workshops and to purchase supplies, such as point-of-care testing kits. The HIT communication and work are predominantly executed virtually.
Each year, teams worked toward achieving goals set nationally. These included increasing HCV birth cohort testing and improving the percentage of patients who had SVR12 testing
(Table).
the percentage of patients who received SVR12 testing posttreatment completion was not included in the HIT Collaborative’s annual goals for the first year of the program. Recognizing this as a critical area for improvement, the HIT CLT set a goal to test 80% of all patients who completed treatment. The HITs applied Lean tools to identify and overcome gaps in the SVR12 testing process. By the end of the second year, 84% of all patients who completed treatment had been tested for SVR12.
The HITs also set specific local VISN and medical center goals, prioritizing projects that could have the greatest impact on local patient access and quality of care and build on existing strengths and address barriers. These projects encompass a wide range of areas that contribute to the overall national goals.
Focus on Lean
Lean process improvement is based on 2 key pillars: respect for people (those seeking service as customers and patients and those providing service as frontline staff and stakeholders) and continuous improvement. With Lean, personnel providing care should work to identify and eliminate waste in the system and to streamline care delivery to maximize process steps that are most valued by patients (eg, interaction with a clinical provider) and minimize those that are not valued (eg, time spent waiting to see a provider). With the knowledge that HHRC fully supports their work, HITs were encouraged to innovate based on local resources, context, and culture.
Teams receive basic training in Lean from the HIT CLT and local systems redesign specialists if available. The HITs apply the A3 structured approach to problem solving.11 The HITs follow prescribed problemsolving steps that help identify where to focus process improvement efforts, including analyzing the current state of care, outlining the target state, and prioritizing solution
approaches based on what will have the highest impact for patients.
to accommodate the outcomes they observe (Figure 2).
Innovations
Over the course of the HIT Collaborative, numerous innovations have emerged to address and mitigate barriers to HCV screening and treatment. Examples of successful innovations include the following:
- To address transportation issues, several teams developed programs specific to patients with HCV in rural locations or with limited mobility. Mobile vans and units traditionally used as mobile cardiology clinics were transformed into HCV clinics, bringing testing and treatment services directly to veterans;
- Pharmacists and social workers developed outreach strategies to locate homeless veterans, provide point-of-care testing and utilize mobile technology to concurrently enroll and link veterans to care; and
- Many liver care teams partnered with inpatient and outpatient substance use treatment clinics to provide patient education and coordinate HCV treatment.
Inter-VISN working groups developed systemwide tools to address common needs. In the program’s first year, a few medical facilities across a handful of VISNs shared local population health management systems, programming, and best practices. Over time, this working group combined the virtual networking capacity of the HIT Collaborative with technical expertise to promote rapid dissemination and uptake of a population health management system. Providers at medical centers across VA use the tools to identify veterans who should be screened and treated for HCV with the ability to continuously update information, identifying patients who do not respond to treatment or patients overdue for SVR12 testing.
Providers with experience using telehepatology formed another inter-VISN working group. These subject matter experts provided guidance to care teams interested in implementing telehealth in areas where limited local resources or knowledge had prevented them from moving forward. The ability to build a strong coalition across content areas fostered a collaborative learning environment, adaptable to implementing new processes and technologies.
In 2017, the VA made significant efforts to reach out to veterans eligible for VA care who had not yet been screened or remained untreated. In May, Hepatitis Awareness Month, HITs held HCV testing and community outreach events and participated in veteran stand-downs and veteran service organization activities.
Evaluation
Since 2014, the VA has increased its HCV treatment and screening rates. To assess the components contributing to these achievements and the role of the HIT Collaborative in driving this success, a team of implementation scientists have been working with the CLT to conduct a HIT program evaluation. The goal of the evaluation is to establish the impact of the HIT Collaborative. The evaluation team catalogs the activities of the Collaborative and the HITs and assesses implementation strategies (use of specific techniques) to increase the uptake of evidence-based practices specifically related to HCV treatment.12
At the close of each FY, HCV providers and members of the HIT Collaborative are queried through an online survey to determine which strategies have been used to improve HCV care and how these strategies were associated with the HIT Collaborative. The use of more strategies was associated with more HCV treatment initiations.13 All utilized strategies were identified whether or not they were associated with treatment starts. These data are being used to understand which combinations of strategies are most effective at increasing treatment for HCV in the VA and to inform future initiatives.
Expanding the Scope
Inspired by the successful results of the HIT work in HCV and in the spirit of continuously improving health care delivery, HHRC expanded the scope of the HIT Collaborative in FY 2018 to include ALD. There are about 80,000 veterans in VA care with advanced scarring of the liver and between 10,000 to 15,000 new diagnoses each year. In addition to HCV as an etiology for ALD, cases of cirrhosis are projected to increase among veterans in care due to metabolic syndrome and alcohol use. A recent review of VA data from fiscal year 2016 found that 88.6% of ALD patients had been seen in primary care within the past 2 years, with about half (51%) seen in a gastroenterology (GI) or hepatology clinic (Personal communication, HIV, Hepatitis, and Related Conditions Program Office March 16, 2018). For patients in VA care with ALD, GI visits are associated with a lower 5-year mortality.14 Annual mortality for all ALD patients in VA is 6.2%, and of those with a hospital admission, mortality rises to 31%.15 In FY 2016, there were about 52,000 ALD-related discharges (more than 2 per patient). Of those discharges, 24% were readmitted within 30 days, with an average length of stay of 1.9 days and an estimated cost per patient of $47,000 over 3 years.16
Hepatologists from across the VA convened to identify critical opportunities for improvement for patients with ALD. Base on available evidence presented in the literature and their clinical expertise, these subject matter experts identified several areas for quality improvement, with the overarching goal to improve identification of patients with early cirrhosis and ensure appropriate linkage to care for all cirrhotic patients, thus improving quality of life and reducing mortality. Although not finalized, candidate improvement targets include consistent linkage to care and treatment for HCV and HBV, comprehensive case management, post-discharge patient follow-up, and adherence to evidence-based standards of care.
Conclusion
The VA has made great strides in nearly eliminating HCV among veterans in VA care. The national effort to redesign hepatitis care using Lean management strategies and develop local and regional teams and centralized support allowed VA to maximize available resources to achieve higher rates of HCV birth cohort testing and treatment of patients infected with HCV than has any other health care system in the US.
The HIT Collaborative has been a unique and innovative mechanism to promote directed, patient-outcome driven change in a large and dynamic health care system. It has allowed rural and urban providers to work together to develop and spread quality improvement innovations and as an integrated system to achieve national priorities. The focus of this foundational HIT structure is expanding to identifying, treat, and care for VA’s ALD population.

The HIT CLT is responsible for executing the HIT Collaborative and uses a Lean process improvement framework focused on eliminating waste and maximizing value. Members of the CLT with expertise in facilitation, Lean process improvement, leadership, clinical knowledge, and population health management act as coaches for the VISN HITs. The CLT works to build and support the VISN HITs, identify opportunities for individual teams to improve and assist in finding the right local mix of “players” to be successful. The HIT CLT ensures all teams are functioning and working toward achieving their goals. The CLT obtains data from VA national databases, which are provided to the VISN HITs to inform and encourage continuous improvement of their strategies. Annual VA-wide aspirational goals are developed and disseminated to encourage a unified mission.
Catchment areas for each VISN include between 6 and 10 medical centers as well as outpatient and ambulatory care centers. Multidisciplinary HITs are composed of physicians, nurses, pharmacists, nurse practitioners, physician assistants, social workers, mental health and substance use providers, peer support specialists, administrators, information technology experts, and systems redesign professionals from medical centers within each VISN. Teams develop strong relationships across medical centers, implement context-specific strategies applicable to rural
and urban centers, and share expertise. In addition to intra-VISN process improvement, HITs collaborate monthly across VISNs via a virtual platform. They share strong practices, seek advice from one another, and compare outcomes on an established set of goals.
The HITs use process improvement tools to systematically assess the current steps involved in care. At the close of each year, the HITs analyze the current state of operations and set goals to improve over the following year guided by a target state map. Seed funding is provided to every VISN HIT annually to launch change initiatives. Many VISN HITs use these funds to support a VISN HIT coordinator, and HITs also use this financial support to conduct 2- to 3-day process improvement workshops and to purchase supplies, such as point-of-care testing kits. The HIT communication and work are predominantly executed virtually.
Each year, teams worked toward achieving goals set nationally. These included increasing HCV birth cohort testing and improving the percentage of patients who had SVR12 testing
(Table).
the percentage of patients who received SVR12 testing posttreatment completion was not included in the HIT Collaborative’s annual goals for the first year of the program. Recognizing this as a critical area for improvement, the HIT CLT set a goal to test 80% of all patients who completed treatment. The HITs applied Lean tools to identify and overcome gaps in the SVR12 testing process. By the end of the second year, 84% of all patients who completed treatment had been tested for SVR12.
The HITs also set specific local VISN and medical center goals, prioritizing projects that could have the greatest impact on local patient access and quality of care and build on existing strengths and address barriers. These projects encompass a wide range of areas that contribute to the overall national goals.
Focus on Lean
Lean process improvement is based on 2 key pillars: respect for people (those seeking service as customers and patients and those providing service as frontline staff and stakeholders) and continuous improvement. With Lean, personnel providing care should work to identify and eliminate waste in the system and to streamline care delivery to maximize process steps that are most valued by patients (eg, interaction with a clinical provider) and minimize those that are not valued (eg, time spent waiting to see a provider). With the knowledge that HHRC fully supports their work, HITs were encouraged to innovate based on local resources, context, and culture.
Teams receive basic training in Lean from the HIT CLT and local systems redesign specialists if available. The HITs apply the A3 structured approach to problem solving.11 The HITs follow prescribed problemsolving steps that help identify where to focus process improvement efforts, including analyzing the current state of care, outlining the target state, and prioritizing solution
approaches based on what will have the highest impact for patients.
to accommodate the outcomes they observe (Figure 2).
Innovations
Over the course of the HIT Collaborative, numerous innovations have emerged to address and mitigate barriers to HCV screening and treatment. Examples of successful innovations include the following:
- To address transportation issues, several teams developed programs specific to patients with HCV in rural locations or with limited mobility. Mobile vans and units traditionally used as mobile cardiology clinics were transformed into HCV clinics, bringing testing and treatment services directly to veterans;
- Pharmacists and social workers developed outreach strategies to locate homeless veterans, provide point-of-care testing and utilize mobile technology to concurrently enroll and link veterans to care; and
- Many liver care teams partnered with inpatient and outpatient substance use treatment clinics to provide patient education and coordinate HCV treatment.
Inter-VISN working groups developed systemwide tools to address common needs. In the program’s first year, a few medical facilities across a handful of VISNs shared local population health management systems, programming, and best practices. Over time, this working group combined the virtual networking capacity of the HIT Collaborative with technical expertise to promote rapid dissemination and uptake of a population health management system. Providers at medical centers across VA use the tools to identify veterans who should be screened and treated for HCV with the ability to continuously update information, identifying patients who do not respond to treatment or patients overdue for SVR12 testing.
Providers with experience using telehepatology formed another inter-VISN working group. These subject matter experts provided guidance to care teams interested in implementing telehealth in areas where limited local resources or knowledge had prevented them from moving forward. The ability to build a strong coalition across content areas fostered a collaborative learning environment, adaptable to implementing new processes and technologies.
In 2017, the VA made significant efforts to reach out to veterans eligible for VA care who had not yet been screened or remained untreated. In May, Hepatitis Awareness Month, HITs held HCV testing and community outreach events and participated in veteran stand-downs and veteran service organization activities.
Evaluation
Since 2014, the VA has increased its HCV treatment and screening rates. To assess the components contributing to these achievements and the role of the HIT Collaborative in driving this success, a team of implementation scientists have been working with the CLT to conduct a HIT program evaluation. The goal of the evaluation is to establish the impact of the HIT Collaborative. The evaluation team catalogs the activities of the Collaborative and the HITs and assesses implementation strategies (use of specific techniques) to increase the uptake of evidence-based practices specifically related to HCV treatment.12
At the close of each FY, HCV providers and members of the HIT Collaborative are queried through an online survey to determine which strategies have been used to improve HCV care and how these strategies were associated with the HIT Collaborative. The use of more strategies was associated with more HCV treatment initiations.13 All utilized strategies were identified whether or not they were associated with treatment starts. These data are being used to understand which combinations of strategies are most effective at increasing treatment for HCV in the VA and to inform future initiatives.
Expanding the Scope
Inspired by the successful results of the HIT work in HCV and in the spirit of continuously improving health care delivery, HHRC expanded the scope of the HIT Collaborative in FY 2018 to include ALD. There are about 80,000 veterans in VA care with advanced scarring of the liver and between 10,000 to 15,000 new diagnoses each year. In addition to HCV as an etiology for ALD, cases of cirrhosis are projected to increase among veterans in care due to metabolic syndrome and alcohol use. A recent review of VA data from fiscal year 2016 found that 88.6% of ALD patients had been seen in primary care within the past 2 years, with about half (51%) seen in a gastroenterology (GI) or hepatology clinic (Personal communication, HIV, Hepatitis, and Related Conditions Program Office March 16, 2018). For patients in VA care with ALD, GI visits are associated with a lower 5-year mortality.14 Annual mortality for all ALD patients in VA is 6.2%, and of those with a hospital admission, mortality rises to 31%.15 In FY 2016, there were about 52,000 ALD-related discharges (more than 2 per patient). Of those discharges, 24% were readmitted within 30 days, with an average length of stay of 1.9 days and an estimated cost per patient of $47,000 over 3 years.16
Hepatologists from across the VA convened to identify critical opportunities for improvement for patients with ALD. Base on available evidence presented in the literature and their clinical expertise, these subject matter experts identified several areas for quality improvement, with the overarching goal to improve identification of patients with early cirrhosis and ensure appropriate linkage to care for all cirrhotic patients, thus improving quality of life and reducing mortality. Although not finalized, candidate improvement targets include consistent linkage to care and treatment for HCV and HBV, comprehensive case management, post-discharge patient follow-up, and adherence to evidence-based standards of care.
Conclusion
The VA has made great strides in nearly eliminating HCV among veterans in VA care. The national effort to redesign hepatitis care using Lean management strategies and develop local and regional teams and centralized support allowed VA to maximize available resources to achieve higher rates of HCV birth cohort testing and treatment of patients infected with HCV than has any other health care system in the US.
The HIT Collaborative has been a unique and innovative mechanism to promote directed, patient-outcome driven change in a large and dynamic health care system. It has allowed rural and urban providers to work together to develop and spread quality improvement innovations and as an integrated system to achieve national priorities. The focus of this foundational HIT structure is expanding to identifying, treat, and care for VA’s ALD population.

A ‘highly effective’ strategy for haplo-HSCT
STOCKHOLM—Researchers have identified a “highly effective” transplant strategy for pediatric patients with primary immunodeficiencies who lack a suitable HLA-compatible donor, according to a speaker at the 23rd Congress of the European Hematology Association (EHA).
The strategy involves α/β T-cell- and B-cell-depleted haploidentical hematopoietic stem cell transplant (haplo-HSCT) followed by infusion of the T-cell product BPX-501.
Children treated with this strategy in a phase 1/2 trial had disease-free and overall survival rates that compared favorably with rates observed in recipients of matched, unrelated transplants.
In addition, the incidence of severe acute and chronic graft-versus-host disease (GHVD) was low in this trial.
Daria Pagliara, MD, PhD, of Ospedale Pediatrico Bambino Gesu in Rome, Italy, presented these results at the recent EHA Congress as abstract S871.
The research was sponsored by Bellicum Pharmaceuticals, Inc., the company developing BPX-501.
BPX-501 consists of genetically modified donor T cells incorporating the CaspaCIDe safety switch, which is designed to eliminate the T cells in the event of toxicity. Rimiducid is used to activate the CaspaCIDe safety switch, which consists of the CID-binding domain coupled to the signaling domain of caspase-9, an enzyme that is part of the apoptotic pathway.
Dr Pagliara explained that T cells are collected from donors via non-mobilized apheresis, the cells are modified to create the BPX-501 product, and the product is infused in HSCT recipients at day 14 after transplant (+/- 4 days).
The patients do not receive GVHD prophylaxis after transplant but are given rimiducid if they develop GVHD that does not respond to standard therapy.
Patients and transplant characteristics
Dr Pagliara reported results with BPX-501 in 59 patients. They had a median age of 1.85 years (range, 0.21 to 17.55), and 57.6% were male.
Patients had severe combined immune deficiency (32%), Wiskott–Aldrich syndrome (15%), chronic granulomatous disease (12%), hemophagocytic lymphohistiocytosis (10%), combined immunodeficiency disease (7%), major histocompatibility complex class II deficiency (5%), and “other” immunodeficiencies (19%).
The patients received BPX-501 after an α/β T-cell-depleted, B-cell-depleted haplo-HSCT. Most patients had a parent donor (94.9%), and 5.1% had a sibling donor. The median donor age was 34 (range, 21-52).
About half of patients (49.2%) received treosulfan-based conditioning, 39% received busulfan-based conditioning, and 11.9% received other conditioning.
The median CD34 dose was 22.0 x 106/kg, and the median α/β T-cell dose was 0.4 x 105/kg.
The median time to BPX-501 infusion was 15 days (range, 11-56). The median time to discharge was 40 days (range, 18-204).
The median follow-up was 536 days (range, 32-1252).
Engraftment and survival
The median time to neutrophil engraftment was 16 days, and the median time to platelet engraftment was 11 days.
Three patients had primary graft failure (5.1%), but 1 of these patients was successfully re-transplanted from the same donor.
The cumulative incidence of transplant-related mortality was 8.7%.
There were 5 cases of transplant-related mortality, which were due to graft failure/disseminated fungal infection, cytomegalovirus (CMV) encephalitis, worsening juvenile dermatomyositis/macrophage activation syndrome, bronchopulmonary hemorrhage, and CMV/adenovirus.
“I would like to underline that 3 of these 5 patients died of infectious complications that were present before the transplant—1 fungal invasive infection, 1 encephalitis due to CMV reactivation, and 1 pulmonary infection due to the presence of adenovirus and cytomegalovirus,” Dr Pagliara said.
The rate of disease-free survival and overall survival were both 87.6%.
GVHD and adverse events
Dr Pagliara said there were low rates of acute GVHD in the first 100 days.
The rate of grade 2-4 acute GVHD was 8.9%, and the rate of grade 3-4 acute GVHD was 1.8%. There were 4 cases of grade 2 GVHD—three stage 3 skin and one stage 1 upper gastrointestinal. There was a single case of grade 3 GVHD—stage 3 liver.
Of the 19 patients who developed acute GVHD, 7 received at least 1 dose of rimiducid. These patients had visceral involvement or GVHD that was not responsive to standard care.
Four patients had a complete response to rimiducid, and 1 had a partial response. One patient did not respond, and 1 was not evaluable. The non-evaluable patient was on corticosteroids and cyclosporine with controlled GVHD but was unable to be weaned off corticosteroids. Rimiducid was given in an attempt to wean the patient off corticosteroids.
“Most importantly, only 1 patient out of 59 developed chronic GVHD, with only mild involvement of the skin,” Dr Pagliara said. This patient did not receive rimiducid.
Nine patients (15.2%) had at least 1 adverse event (AE).
AEs occurring after BPX-501 administration were grade 1 or 2 in nature. They included diarrhea, vomiting, pyrexia, CMV viremia, rhinovirus infection, hypokalemia, pruritus, and rash.
There were no severe AEs attributed to BPX-501.

Dr Pagliara said there were low rates of acute GVHD in the first 100 days.
The rate of grade 2-4 acute GVHD was 8.9%, and the rate of grade 3-4 acute GVHD was 1.8%. There were 4 cases of grade 2 GVHD—three stage 3 skin and one stage 1 upper gastrointestinal. There was a single case of grade 3 GVHD—stage 3 liver.
Of the 19 patients who developed acute GVHD, 7 received at least 1 dose of rimiducid. These patients had visceral involvement or GVHD that was not responsive to standard care.
Four patients had a complete response to rimiducid, and 1 had a partial response. One patient did not respond, and 1 was not evaluable. The non-evaluable patient was on corticosteroids and cyclosporine with controlled GVHD but was unable to be weaned off corticosteroids. Rimiducid was given in an attempt to wean the patient off corticosteroids.
“Most importantly, only 1 patient out of 59 developed chronic GVHD, with only mild involvement of the skin,” Dr Pagliara said. This patient did not receive rimiducid.
Nine patients (15.2%) had at least 1 adverse event (AE).
AEs occurring after BPX-501 administration were grade 1 or 2 in nature. They included diarrhea, vomiting, pyrexia, CMV viremia, rhinovirus infection, hypokalemia, pruritus, and rash.
There were no severe AEs attributed to BPX-501.
Perioperative RBC transfusions linked to VTE
Patients who receive red blood cell (RBC) transfusions before, during, or immediately after surgery may have an increased risk of venous thromboembolism (VTE), a new study suggests.
In this retrospective study, transfusion recipients had twice the risk of VTE as patients who did not receive RBC transfusions during the perioperative period.
Investigators say these findings require validation, but they suggest a need for physicians to consider non-transfusion alternatives to treat anemia in patients undergoing surgery.
“These findings reinforce the importance of following rigorous perioperative patient blood management practices for transfusions,” said Ruchika Goel, MD, of Weill Cornell Medicine in New York, New York.
Dr Goel and her colleagues reported their findings in JAMA Surgery.
The investigators analyzed data on 750,937 patients who underwent surgery in 2014. In all, 6.3% (n=47,410) of patients received at least one RBC transfusion.
Within 30 days of surgery, 0.8% (n=6309) of all patients had a VTE. This included 0.6% (n=4336) with deep vein thrombosis (DVT), 0.3% (n=2514) with pulmonary embolism (PE), and 0.1% (n=541) with DVT and PE.
Analyses showed that patients who received RBC transfusions were twice as likely to develop VTE as those who did not receive transfusions (adjusted odds ratio [aOR]=2.1). This was true for both DVT (aOR=2.2) and PE (aOR=1.9).
“We also saw this risk across different surgical disciplines, ranging from neurosurgery to cardiac surgery,” said study author Aaron Tobian, MD, PhD, of Johns Hopkins University School of Medicine in Baltimore, Maryland.
Furthermore, VTE risk increased with the number of RBC transfusions a patient received. The aORs were 2.1 for 1 transfusion, 3.1 for 2 transfusions, and 4.5 for 3 or more transfusions (compared to patients who did not receive any transfusions).
“This retrospective study demonstrates that there may be additional risks to blood transfusion that are not generally recognized in the community,” Dr Tobian said. “While additional research is needed to confirm these results, the findings reinforce the need to limit blood transfusions to only when necessary.”

Company stops development of eryaspase in ALL
Erytech Pharma said it plans to stop development of eryaspase for acute lymphoblastic leukemia (ALL).
This means withdrawal of the European marketing authorization application for eryaspase as a treatment for relapsed and refractory ALL.
However, Erytech will continue development of eryaspase as a treatment for certain solid tumor malignancies.
Eryaspase consists of L-asparaginase encapsulated inside donor-derived red blood cells. These enzyme-loaded red blood cells function as bioreactors to eliminate circulating asparagine and “starve” cancer cells, thereby inducing their death.
Erytech noted that eryaspase has produced favorable efficacy and safety results in ALL.
However, based on recent feedback from regulatory agencies in Europe and the US, the company believes significant additional investment would be required to seek regulatory approval of eryaspase for the treatment of ALL. Erytech also believes there would be a limited market opportunity for eryaspase in ALL.
Therefore, the company decided to cease further clinical development efforts in ALL. The resources that will become available as a result of this decision will be allocated to the development of eryaspase in solid tumors.
In 2017, Erytech announced results from a phase 2b clinical trial of eryaspase plus chemotherapy in patients with second-line metastatic pancreatic cancer. The company expects to begin enrollment in a phase 3 trial of this patient population in the third quarter of 2018.
In addition, Erytech is preparing for a pair of phase 2 proof-of-concept trials of eryaspase. One is in first-line pancreatic cancer, and the other is in metastatic triple-negative breast cancer. The company is also evaluating development options in additional solid tumor indications with high unmet medical need.
To ensure an adequate supply of eryaspase, Erytech is constructing a large-scale manufacturing facility in Princeton, New Jersey, and is expanding its manufacturing capacity in Lyon, France. The company expects both facilities to be operational for clinical production at the expanded capacity in the first quarter of 2019.

HCV remodels lipid metabolism in infected cells
Hepatitis C virus infection often is associated with the accumulation of fat in hepatocytes, which shows a connection between the virus and the lipid metabolism of the liver, according to Sarah Hoffman, MD, of the Leibniz Institute for Experimental Virology, Hamburg, Germany, and her colleagues. “Our study provides a detailed analysis of the changes in the lipid composition in HCV-infected cells that revealed dependency on FA [fatty acid] elongation and desaturation for effective viral replication and virion production,” they reported.
Dr. Hoffman and her colleagues assessed lipid composition of infected cells in an in vitro study of cell lines, which were assessed 8-11 days post infection, according to the report published in BBA: Molecular and Cell Biology of Lipids. They determined the abundance of each major lipid class and compared the pattern of HCV-infected cells with that of controls.
The researchers found that HCV caused an accumulation of membrane phosopholipids but not neutral lipids and that cholesterol accumulated in the perinuclear region of HCV-infected cells. In addition, lipid species with longer fatty acyl chains were more abundant in HCV-infected cells and free polyunsaturated fatty acid (PUFA) levels were greatly increased.
In further confirmation of the critical role of lipid metabolism in HCV replication, they found that knockdown of fatty acid elongases and desaturases disrupted HCV replication, while overexpression of these enzymes showed a proviral effect.
“We identified several lipid-remodeling pathways that are required for distinct steps in viral infection. Future studies have to address the molecular function of longer fatty acyl chains in HCV RNA replication and why PUFAs are needed for HCV particle production,” the researchers concluded.
The authors reported government and institutional-only funding and no personal disclosures.

CPAP and oxygen have different cardiac effects in OSA
BALTIMORE – Continuous positive airway pressure (CPAP) may supersede supplemental oxygen and patient education for improving one key marker of cardiac electrophysiological autonomic function during sleep, but supplemental oxygen may have the upper hand in improving a second key electrophysiological biomarker, according to results of a multicenter, randomized clinical trial presented at the annual meeting of the Associated Professional Sleep Societies.
“Based on these findings, it appears that there are opposing alterations in both frequency and time domain in heart rate variability indices in the CPAP versus oxygen groups,” said Jenie George, MD, of the Cleveland Clinic.
The study evaluated 3-month outcomes of frequency-based heart rate variability (HRV) indices obtained with ECG from sleep studies in 203 patients with obstructive sleep apnea and increased cardiovascular risk in the Heart Biomarker Elevation in Apnea Treatment (HeartBEAT) trial. The interventions were either CPAP, supplemental oxygen, or healthy lifestyle education. Dr. George noted that HRV is a noninvasive tool to evaluate autonomic function by quantifying changes in intervals between sinus beats during sleep.
On the high-frequency power index, patients on CPAP had a 9% reduction versus a 19% increase for those on supplemental oxygen, Dr. George said. However for the low frequency to high frequency ratio, the CPAP group had a 4% increase, whereas the oxygen group had a 34% reduction.
The increase of low frequency to high frequency ratio in the CPAP group is a reflection of sympathovagal balance – the ratio between low-frequency and high-frequency powers – while the changes in high-frequency power in the CPAP patients reflect changes in sinoatrial node electrophysiological function, Dr. George said.
Strengths of the study were its use of data from a large clinical trial, careful preprocessing of ECG data, and consideration of the influence of oxygen in sleep apnea and of confounding influences, such as medications. Limitations of the study, Dr. George noted, include the absence of sleep-wake data and acknowledgment that HRV measures are accepted surrogates of autonomic imbalance but that they are not direct measures.
The next steps for the current research, Dr. George said, include an analysis of how respiratory events influence HRV indices in CPAP and supplemental oxygen. Future trials should be designed to examine how the two interventions affect direct measures of autonomic function and consider a longer follow-up duration, she said.
Dr. George had no financial relationships to disclose. The trial received support from the National Heart, Lung, and Blood Institute and the National Center for Research Resources.

Prompting during rounds decreases lab utilization in patients nearing discharge
Clinical question: Does prompting hospitalists during interdisciplinary rounds to discontinue lab orders on patients nearing discharge result in a decrease in lab testing?
Background: The Society of Hospital Medicine, as part of the Choosing Wisely campaign, has recommended against “repetitive complete blood count and chemistry testing in the face of clinical and lab stability.” Repeated phlebotomy has been shown to increase iatrogenic anemia and patient discomfort. While past interventions have been effective in decreasing lab testing, this study focused on identifying and intervening on patients who were clinically stable and nearing discharge.
Study design: Prospective, observational study.
Setting: Tertiary care teaching hospital in New York.
Synopsis: As part of structured, bedside, interdisciplinary rounds, over the course of a year, this study incorporated an inquiry to identify patients who were likely to be discharged in the next 24-48 hours; the unit medical director or nurse manager then prompted staff to discontinue labs for these patients when appropriate. This was supplemented by education of clinicians and regular review of lab utilization data with hospitalists.
The percentage of patients with labs ordered in the 24 hours prior to discharge decreased from 50.1% in the preintervention period to 34.5% in the postintervention period (P = .004). The number of labs ordered per patient-day dropped from 1.96 to 1.83 (P = .01).
Bottom line: An intervention with prompting during structured interdisciplinary rounds decreased the frequency of labs ordered for patients nearing hospital discharge.

Ozenoxacin is a novel treatment option for impetigo
Ozenoxacin (Xepi cream), a potent novel topical antibacterial agent, is effective and well tolerated for treatment of impetigo in patients aged 2 months and older, according to results of a phase 3 randomized, double-blind, vehicle-controlled clinical trial.
A 1% cream formulation of ozenoxacin had a clinical and microbiologic response that was rapid and superior to placebo, investigators reported in this second phase 3 pivotal study, which demonstrated the efficacy of ozenoxacin cream in impetigo patients.
“With concerns over widespread antibiotic resistance, ozenoxacin is an important potential treatment option with an expanded spectrum against bacterial pathogens, including those resistant to mupirocin, ciprofloxacin, and methicillin, including MRSA [methicillin-resistant Staphylococcus aureus],” Dr. Rosen and his colleagues wrote in a report on their study in JAMA Dermatology.
The clinical trial included 412 patients aged 2 months or older with impetigo. Clinical success, defined as complete absence of the treated lesions, was seen after 5 days of treatment in 112 of the 206 (54.4%) patients randomized to ozenoxacin versus 78 of 206 patients (37.9%) who received placebo (P = .001), which confirmed the superiority of ozenoxacin, Dr. Rosen and his coauthors wrote.
In addition, microbiologic response was seen in 87.2% of patients in the ozenoxacin group during therapy (day 3) versus 63.9% in the placebo group (P = .002); by the end of therapy (day 6), response rates were 92.0% and 73.1%, respectively (P = .005).
All patients with drug-resistant infections had clinical cure or improvement at the end of treatment, including 10 patients with mupirocin-resistant S. aureus and 8 patients with MRSA, investigators wrote.
Adverse event rates were low for both ozenoxacin and placebo groups, at 3.9% and 3.4%, respectively. One patient in the ozenoxacin group experienced a serious adverse event “at least potentially related” to treatment (rosacea and seborrheic dermatitis).
“The lack of systemic adverse effects is consistent with previous studies that demonstrated that topically applied ozenoxacin has negligible systemic absorption,” Dr. Rosen and his coauthors wrote.
The study was partly supported by Ferrer Internacional; two coauthors of the study reported employment with that company. Dr. Rosen reported consulting work with Medimetriks Pharmaceuticals, which developed the agent.

Ozenoxacin (Xepi cream), a potent novel topical antibacterial agent, is effective and well tolerated for treatment of impetigo in patients aged 2 months and older, according to results of a phase 3 randomized, double-blind, vehicle-controlled clinical trial.
A 1% cream formulation of ozenoxacin had a clinical and microbiologic response that was rapid and superior to placebo, investigators reported in this second phase 3 pivotal study, which demonstrated the efficacy of ozenoxacin cream in impetigo patients.
“With concerns over widespread antibiotic resistance, ozenoxacin is an important potential treatment option with an expanded spectrum against bacterial pathogens, including those resistant to mupirocin, ciprofloxacin, and methicillin, including MRSA [methicillin-resistant Staphylococcus aureus],” Dr. Rosen and his colleagues wrote in a report on their study in JAMA Dermatology.
The clinical trial included 412 patients aged 2 months or older with impetigo. Clinical success, defined as complete absence of the treated lesions, was seen after 5 days of treatment in 112 of the 206 (54.4%) patients randomized to ozenoxacin versus 78 of 206 patients (37.9%) who received placebo (P = .001), which confirmed the superiority of ozenoxacin, Dr. Rosen and his coauthors wrote.

Cigarette smoking epidemic among HCV-infected individuals
There is a cigarette smoking epidemic embedded within the hepatitis C virus epidemic in the United States, according to the results of an analysis of data between 1999 and 2014 from the National Health and Nutrition Examination Survey (NHANES).
Smoking and hepatitis C information were available for 90.1% of the NHANES adult population. Of the 39,472 individuals evaluated, 1.3% were hepatitis C+ and 22.3% were current smokers. Hepatitis C+ individuals were almost three times as likely to be smokers as were those who were hepatitis C– (62.4% vs. 22.9%, respectively), according to the report, published in The American Journal of Medicine (Am J Med. 2018 Jun;131[6]:699-75).
Ryung S. Kim, PhD, of Albert Einstein College of Medicine, New York, and his colleagues also found that hepatitis C+ smokers were more likely to be older, male, black, less educated, poor, and uninsured compared with their hepatitis C– smoking counterparts. They also were more likely to use drugs, including heroin, and to be depressed.
Multivariate analysis showed a significant association of both hepatitis C infection and smoking with current depression and hypertension, Dr. Kim and his colleagues wrote.
“It is public health folly to spend tens of millions of dollars annually” on treatment of hepatitis C patients, “and ignore the lethal addiction affecting more than 60% of them. As we enter a new era of hepatitis C treatment, it is a public health imperative to research, develop, and implement tobacco treatments for the hepatitis C+ community,” Dr. Kim and his colleagues concluded.
The authors reported that they had no conflicts of interest.
