Programs that give physicians real-time feedback and financial incentives may lead to improvements in hospital safety, according to a study published in the Journal of Hospital Medicine.
The study showed that hospitalists significantly improved their compliance with practice guidelines for preventing venous thromboembolism (VTE)
when they could get feedback on their compliance rates and a direct financial incentive for improving their performance.
“Our study confirms there is a real return on investment in such programs, not only for patient safety but also for hospitals,” said study author Henry Michtalik, MD, of Johns Hopkins Hospital in Baltimore, Maryland.
“Metrics such as the use of preventive drugs for [VTE] are already being monitored but only really improve a hospital’s quality of care when programs get data back to the people who are treating patients to directly improve care.”
Dr Michtalik and his team found that, by providing such information to physicians through web-based, real-time displays, monthly VTE prophylaxis compliance rates improved from 86% to 90% in 6 months.
Adding pay-for-performance to the real-time feedback for the following 18 months boosted compliance rates to 94%.
Dr Michtalik pointed out that “no one got wealthy off of the pay-for-performance program. Instead, we believe the money served more as a method to engage the providers.”
Payments ranged from $53 to $1244, with all but 2 of the incentive payments totaling under $1000. And it was during the 6-month feedback-only period that compliance rose the fastest.
The study involved 38 part-time and full-time academic hospitalists and the analysis of 3144 inpatients with a median stay of 3 days. The most common diagnoses were heart failure, acute kidney failure, temporary loss of consciousness (syncope), pneumonia, and chest pain.
Following the evidence-based guidelines of the American College of Chest Physicians for VTE prevention, physicians in the study were required to complete a VTE-risk assessment for each patient by using the hospital’s computerized provider order entry system.
“It sort of walks you through the thinking process” for making the VTE-risk assessment, Dr Michtalik said.
The system then prompted physicians with a risk-appropriate recommendation, but it was up to physicians to order the treatment itself. That allowed for physician discretion among types of prevention, as well as for patient and physician preference.
Before implementing the feedback system, the researchers established a 2-year baseline and found that physicians in the study prescribed inappropriate prophylaxis 7.9% of the time and did not prescribe prophylaxis when indicated 6.1% of the time.
Overall, the choice of inappropriate preventive treatment dropped to 6.2% with real-time feedback and to 2.6% with the addition of pay-for-performance. Lack of prophylaxis when indicated fell to 3.2% with feedback and to 3.1% with pay-for-performance.
Dr Michtalik noted that continuous improvements depend not only on the right kind of feedback but also on efforts to avoid “information overload,” especially now that an increasing amount of health and medical records are electronic.
“So you specifically target a few things that need to be improved,” he said, “and really incorporate them into the hospital’s culture.”

Analyses reveal higher-than-expected pediatric cancer rates in Florida

Several statistical analyses have revealed higher-than-expected rates of pediatric cancers in 2 regions of Florida—the Miami metro area and an area west of the Everglades.
The anomalous rates were detected by 5 different research teams—each using different epidemiological and statistical methodology—on a data set spanning the period from 2000 to 2010 that was provided by the Florida Association of Pediatric Tumor Programs (FAPTP).
Lance A. Waller, PhD, of Emory University in Atlanta, Georgia, reviewed the different analyses and described his findings in Statistics and Public Policy.
The research groups applied different analytical approaches to achieve the same goal: detect spatio-temporal pediatric cancer clusters. The analyses used familiar methods—scan statistics, classification, and hierarchical Bayesian modeling—as well as some ideas new to disease clustering: wombling and machine learning.
During their respective analyses of the FAPTP data, the research groups found several suggestive results. For instance, each approach identified local areas in which the observed pediatric cancer rate is significantly higher than the rate expected, given the number of people at risk.
While the precise areas of high reported risk differ between methods, the groups identified a few common results that overlap but are not identical.
For example, all 5 teams identified significantly elevated rates of pediatric cancers in an urban area within collections of ZIP code tabulation areas (ZCTAs) in the Miami metro area and in an area just west of the Everglades. (ZCTAs are geographic areas defined by the US Census Bureau to provide a link between census geography—blocks, block groups, and tracts—and US Postal Service ZIP code areas.)
One analysis suggested the local increase west of the Everglades is based on 2 cases, both classified as “other” race, while another analysis indicated that this cluster is limited to the year 2000.
The observed elevated rates near Miami involved a much larger population size and many more cases, factors that complicate the identification of any shared characteristics common to cases in the cluster.
The analyses also revealed other patterns in the data. Dr Waller said an analysis that revealed a statewide increase in the baseline pediatric cancer incidence rate occurring between 2005 and 2006 merits a closer look to see whether this result represents an overall increase in risk or a change in reporting, because the statistical analysis does not reveal potential reasons for the change.
There also are subtle differences between the specific clusters identified by the various analytical approaches. Comparisons across analyses revealed characteristics of the detected patterns, including the number of cases (2), types of cancer (leukemia or brain/central nervous system cancer), and the racial composition and timing of the cluster west of the Everglades.
As the methods the researchers used don’t completely agree on the precise location, boundaries, and make-up of the detected clusters, the findings suggest a single method may not prove sufficient for such analyses, Dr Waller said.
He added that the identified clusters are geographically quite large and therefore unlikely to provide clear links between particular environmental exposures to local risks.
“While the results do not identify a ‘smoking gun’ in the form of a shared environmental exposure in high-incidence areas, the results do provide epidemiologic insight into the local demographics of the incidence of pediatric cancer cases and suggest more detailed assessment of migration patterns in the Miami area,” Dr Waller said.
“Policy-wise, the results point to responsibly responsive next steps of detailed description of the cases and the at-risk population in the detected areas to summarize local features in the data, particularly the race of cases west of the Everglades and demographic descriptors of any shifts in the at-risk population in the Miami area during the study period.”
Policy responses by local and state health officials may involve more detailed follow-up, including additional data collection, exposure surveys, or in-depth investigation of case histories within a reported cluster.
Dr Waller added that estimated cancer rates consist of the local number of cases (reported by the FAPTP) and the local number of children at risk (reported by the decennial census). Higher-than-expected rates can result from unusually high numbers of reported cases or low numbers of reported local residents.
Since Miami, like many urban areas, often experiences rapid changes in population size and composition between decennial censuses, it is important to assess the accuracy of both data components. Dr Waller suggested, as a first step, assessing the accuracy of the case counts and the inter-census population projections defining the local rates.
“State and local health departments and public health agencies regularly respond to cluster reports from the public,” he said. “Typically, a responsive and effective response is not based on a detailed new epidemiologic study but, rather, is based on education, assessments of local concentrations of demographic risk factors associated with the reported cluster, and an assessment of the distribution of numbers of cases expected given the local demographics.”

Fake malaria drugs may be less common than we thought

Investigations into antimalarial drug quality conducted in Cambodia and Tanzania uncovered no evidence of fake medicines.
Previous reports had suggested that up to a third of antimalarials might be falsified, or do not contain the stated active pharmaceutical ingredient.
The new research revealed no falsified drugs in either country, but it did unearth substandard antimalarial drugs, or genuine medicines that do not have the correct amount of the active ingredient.
These findings were published in 2 articles in the American Journal of Tropical Medicine and Hygiene.
“Although there have been alarming reports about the prevalence of fake antimalarials, our study provides ample data showing that the quality of drugs is not so bad based on comprehensive sampling and analysis presented here,” said Harparkash Kaur, PhD, of the London School of Hygiene & Tropical Medicine in the UK.
“The lack of falsified medicines in Cambodia and Tanzania are reassuring, but the presence of substandard medicines is definitely a concern.”
The researchers analyzed 2028 antimalarials from Tanzania and Cambodia at 3 independent laboratories in the UK and US. They classified drugs as acceptable, falsified, or substandard.
In Tanzania, the researchers used an “overt sampling” system, telling vendors they were going to analyze the quality of their medicines.
In Cambodia, the researchers used overt sampling as well as a “mystery client” approach, where actors pretended to be patients with malaria, or their relatives, and bought the medicines offered to them.
Both studies used a randomized approach to sampling of drug outlets, which differs from previous studies that mostly used non-representative methods for selecting drugs for analysis.
Neither study unearthed falsified drugs, but substandard drugs were found in 31% of samples in Cambodia and 12% of samples in Tanzania.
“Falsified medicines have received much attention globally, but substandard drugs are far more prevalent and of great concern,” said Shunmay Yeung, MBBS, PhD, also of the London School of Hygiene & Tropical Medicine.
“Not only do they leave patients with malaria undertreated, which could be fatal, but they may also contribute to the development of resistance to [artemisinin-based combination therapies], the most effective drugs for malaria. Generally, the fact that no falsified antimalarials were identified reflects the positive impact of the [countries’ efforts] to control drug quality.”

Alzheimer’s drug improves cognitive function after RT for brain tumors
Adult brain tumor survivors taking donepezil, a drug approved for the treatment of Alzheimer’s disease, showed significant improvements in the cognitive functions of memory, motor speed, and dexterity, compared with those taking a placebo. However, improvements in the primary outcome of composite cognitive function were similar for the two arms, investigators reported.
The study results were published online April 20 in the Journal of Clinical Oncology.
Patients with greater pretreatment deficits saw greater improvements in cognitive functioning with donepezil treatment, reported Stephen Rapp, Ph.D., professor of psychiatry and behavioral medicine at Wake Forest School of Medicine, Winston-Salem, N.C., and associates.
“This suggests that treatment with a daily dose of donepezil can provide benefit to some adult long-term brain tumor survivors after PBI or WBI [partial- or whole-brain irradiation], particularly those with greater pretreatment cognitive impairment,” they wrote (J. Clin. Oncol. 2015 Apr. 20 [doi: 10.1200/JCO.2014.58.4508]).
The phase III trial enrolled 198 primary or metastatic brain tumor survivors who underwent fractionated PBI or WBI at least 6 months previously. Patients received either donepezil at 5 mg daily for 6 weeks, followed by 10 mg daily for 18 weeks if well tolerated, or placebo for 24 weeks. Composite cognitive scores improved for both arms and did not differ significantly. Donepezil treatment resulted in significantly greater improvements in memory (recognition, P = .027; discrimination, P = .007) and motor speed and dexterity (P = .016).
Donepezil was generally well tolerated, except for diarrhea in 25% of the active arm vs. 9% in the placebo arm (P = .005). The study retention rate was 74% at 24 weeks for both groups.
Although enrolled patients had a high level of cognitive impairment relative to noncancer controls, with 91% having at least one test score at least 1.5 standard deviations below the normal comparison group, scores across most measures varied widely from significantly lower to higher than the comparison group. This heterogeneity may underlie the less than significant improvement observed with the study treatment. Patients with greater cognitive deficits saw greater benefits.
“This indicates that brain tumors and their treatments, including cranial irradiation, are associated with clinically significant cognitive impairment among some but not all patients. In future studies, demonstrable cognitive impairment should be an inclusion criterion for enrollment,” Dr. Rapp and associates wrote.
The study by Rapp et al. suggests that for brain tumor survivors experiencing cognitive difficulties, intervention with donepezil, a drug approved for use in Alzheimer’s disease (AD), may be helpful. Although average improvements were small, the trial indicates clear benefit for some patients, especially those most impaired. The study followed patients taking the drug for 6 months, but patients who responded to treatment likely will continue with lifelong therapy, based on experience with donepezil in AD. After cessation of the agent, neurocognitive function of treated AD patients declined to the level of untreated patients.
The results of the current study justify administering the drug to affected patients and monitoring for effects. In the absence of evidence of clinical benefit, the data do not support continuing treatment. Donepezil use in AD is continued for some patients even without signs of improvement, on the basis of slowing expected decline. However, cognitive declines due to tumor and treatment injury do not progress over time, and donepezil use in this population is supported only with evidence of benefit.
Optimal dosing for cancer patients requires further study, but studies with AD patients showed no clear benefit of dose escalation that outweighed GI adverse effects.
Maintaining maximal cognitive functioning in patients who often begin treatment with brain injury due to the tumor and unrelated illnesses, requires first the prevention of further damage. Strategies include functional image-guided surgery, limiting daily radiation fraction size, improved image-guided radiotherapy target definition, highly conformal radiotherapy administration techniques, and highly focused stereotactic radiosurgery in place of whole-brain radiotherapy for many patients with brain metastasis. Research on improvements in imaging of tumor and functional brain to better guide surgery and radiation is worthwhile.
Neurocognitive rehabilitation is recommended for patients with cognitive deficits that persist after therapy had ended. A recent randomized study showed clear benefit of rehabilitation for attention, verbal memory, and mental fatigue.
By taking steps to prevent injury, rehabilitate patients with deficits, and administer drug therapies while monitoring for benefit, improvements to cognitive function in brain tumor survivors may begin to increase. To best employ these strategies, a validated, easy-to-use instrument that measures mild to moderate impairment is needed for routine oncology practice.
Dr. Lawrence Kleinberg is associate professor of radiation oncology and molecular radiation sciences at Johns Hopkins Sidney Kimmel Comprehensive Cancer Center, Baltimore.

However, cognitive declines due to tumor and treatment injury do not progress over time, and donepezil use in this population is supported only with evidence of benefit.
Optimal dosing for cancer patients requires further study, but studies with AD patients showed no clear benefit of dose escalation that outweighed GI adverse effects.
Maintaining maximal cognitive functioning in patients who often begin treatment with brain injury due to the tumor and unrelated illnesses, requires first the prevention of further damage. Strategies include functional image-guided surgery, limiting daily radiation fraction size, improved image-guided radiotherapy target definition, highly conformal radiotherapy administration techniques, and highly focused stereotactic radiosurgery in place of whole-brain radiotherapy for many patients with brain metastasis. Research on improvements in imaging of tumor and functional brain to better guide surgery and radiation is worthwhile.
Neurocognitive rehabilitation is recommended for patients with cognitive deficits that persist after therapy had ended. A recent randomized study showed clear benefit of rehabilitation for attention, verbal memory, and mental fatigue.
By taking steps to prevent injury, rehabilitate patients with deficits, and administer drug therapies while monitoring for benefit, improvements to cognitive function in brain tumor survivors may begin to increase. To best employ these strategies, a validated, easy-to-use instrument that measures mild to moderate impairment is needed for routine oncology practice.

The study by Rapp et al. suggests that for brain tumor survivors experiencing cognitive difficulties, intervention with donepezil, a drug approved for use in Alzheimer’s disease (AD), may be helpful. Although average improvements were small, the trial indicates clear benefit for some patients, especially those most impaired. The study followed patients taking the drug for 6 months, but patients who responded to treatment likely will continue with lifelong therapy, based on experience with donepezil in AD. After cessation of the agent, neurocognitive function of treated AD patients declined to the level of untreated patients.
The results of the current study justify administering the drug to affected patients and monitoring for effects. In the absence of evidence of clinical benefit, the data do not support continuing treatment. Donepezil use in AD is continued for some patients even without signs of improvement, on the basis of slowing expected decline. However, cognitive declines due to tumor and treatment injury do not progress over time, and donepezil use in this population is supported only with evidence of benefit.

Adult brain tumor survivors taking donepezil, a drug approved for the treatment of Alzheimer’s disease, showed significant improvements in the cognitive functions of memory, motor speed, and dexterity, compared with those taking a placebo. However, improvements in the primary outcome of composite cognitive function were similar for the two arms, investigators reported.
The study results were published online April 20 in the Journal of Clinical Oncology.
Patients with greater pretreatment deficits saw greater improvements in cognitive functioning with donepezil treatment, reported Stephen Rapp, Ph.D., professor of psychiatry and behavioral medicine at Wake Forest School of Medicine, Winston-Salem, N.C., and associates.
“This suggests that treatment with a daily dose of donepezil can provide benefit to some adult long-term brain tumor survivors after PBI or WBI [partial- or whole-brain irradiation], particularly those with greater pretreatment cognitive impairment,” they wrote (J. Clin. Oncol. 2015 Apr. 20 [doi: 10.1200/JCO.2014.58.4508]).
The phase III trial enrolled 198 primary or metastatic brain tumor survivors who underwent fractionated PBI or WBI at least 6 months previously. Patients received either donepezil at 5 mg daily for 6 weeks, followed by 10 mg daily for 18 weeks if well tolerated, or placebo for 24 weeks. Composite cognitive scores improved for both arms and did not differ significantly. Donepezil treatment resulted in significantly greater improvements in memory (recognition, P = .027; discrimination, P = .007) and motor speed and dexterity (P = .016).
Donepezil was generally well tolerated, except for diarrhea in 25% of the active arm vs. 9% in the placebo arm (P = .005). The study retention rate was 74% at 24 weeks for both groups.
Although enrolled patients had a high level of cognitive impairment relative to noncancer controls, with 91% having at least one test score at least 1.5 standard deviations below the normal comparison group, scores across most measures varied widely from significantly lower to higher than the comparison group. This heterogeneity may underlie the less than significant improvement observed with the study treatment. Patients with greater cognitive deficits saw greater benefits.
“This indicates that brain tumors and their treatments, including cranial irradiation, are associated with clinically significant cognitive impairment among some but not all patients. In future studies, demonstrable cognitive impairment should be an inclusion criterion for enrollment,” Dr. Rapp and associates wrote.

ABVD and Stanford V similar for bulky mediastinal Hodgkin’s lymphoma
Failure-free survival and overall survival were similar between two combined modality therapies in patients with stage I or II bulky mediastinal Hodgkin’s lymphoma, investigators reported.
The results were published online April 20 in the Journal of Clinical Oncology.
The phase III trial evaluated outcomes following treatment with either doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) or mechlorethamine, doxorubicin, vincristine, bleomycin, vinblastine, etoposide, and prednisone (Stanford V).
Median failure-free survival (FFS) and overall survival (OS) were not reached in either arm. The 5-year FFS and OS were 85% and 96% for ABVD, respectively, and 79% and 92% for Stanford V, reported Dr. Ranjana H. Advani, professor of oncology at Stanford (Calif.) University, and associates.
At a median follow up of 6.54 years, 19 treatment failures occurred in the ABVD arm and 23 in the Stanford V arm. In total, 14 deaths occurred, 5 in the ABVD group and 9 in the Stanford V group.
Approximately 20%-25% of patients with stage I or II Hodgkin’s lymphoma (HL) have bulky mediastinal involvement, and this was the first contemporary prospective trial to evaluate this patient subgroup, the investigators wrote (J. Clin. Oncol. 2015 April 20 [doi:10.1200/JCO.2014.57.8138]).
“This is important because ongoing trials in North America use mediastinal bulk as an eligibility criterion, and contemporary guidelines use it to define treatment algorithms,” Dr. Advani and associates said, noting that both regimens are acceptable treatment options.
“In addition, these results provide an important contemporary benchmark for comparison of ongoing and future studies,” they wrote.
Out of 854 patients with HL enrolled in the trial, 264 with bulky disease were eligible for the subgroup analysis; 135 received ABVD and 129 received Stanford V. After completion of chemotherapy, all patients received 36 Gy of modified involved field radiotherapy (IFRT). Patterns of relapse were similar between treatment arms, and less than 10% of patients had in-field recurrences, a finding that indicated effective local control with IFRT.
Both treatment arms had similar rates of grade 3-4 neutropenia, and the Stanford V arm had more grade 3 lymphopenia (83% vs. 46%, P < .001) and grade 3 and 4 sensory neuropathy. At 5 years, both groups had similar risks of second cancers: two in the ABVD group and six in the Stanford group. The assessment of risks associated with higher doses of anthracycline and bleomycin in ABVD and larger radiation fields in Stanford V requires longer follow-up, the researchers wrote.

NSAIDs for depression
At the risk of stating the obvious, our patients are becoming increasingly complex. Life is prolonged and comorbidities accumulate, creating dizzying laundry lists of medical problems.
Within the context of clinical or, increasingly, nonreimbursed telephonic or electronic visits, we attack the medical problem with the worst severity in an attempt to tamp it down to the level of its comorbid brethren.
Almost without exception, depression rears its ugly head in our sickest patients. Antidepressants will be started and added to the three pages (double-spaced, with 1-inch margins) of medications.
But in all of these patients, are we treating the disease or just the symptom? What if inflammation is causing the depression? Will reduction of inflammation treat the depression?
Dr. Ole Köhler of Aarhus University Hospital, Denmark, and his colleagues conducted a systematic review on the antidepressant effects of anti-inflammatory medications (JAMA Psychiatry 2014;71:1381-91). Fourteen trials informed the meta-analysis, 10 that evaluated NSAID drugs (for example, celecoxib, naproxen, ibuprofen), and 4 that investigated cytokine inhibitors (for example, etanercept, infliximab). Six of the 10 NSAID studies evaluated NSAIDs as monotherapy. All four of the cytokine-inhibitor trials evaluated them as monotherapy. Length of treatment was between 6 and 12 weeks.
The pooled effect suggests that anti-inflammatory treatment reduced depressive symptoms. Celecoxib seemed to have the strongest effect on remission and clinical response. No increase in adverse events was reported.
We know that proinflammatory drugs can induce depression. So the opposite is quite possibly true, and these data suggest it to be so. Findings suggest that reducing the inflammatory state among our patients with depression may be a useful adjunct to antidepressant therapy, at least in the initial period.
Whatever we can do to facilitate depressive symptom relief seems a worthy goal. So, here again, we could tell our patients presenting with depression to take two (with an SSRI, perhaps) and call us in the morning. But how best to do this and in what patients remains uncertain.

Low-risk PE patients can be treated as outpatients
Patients with pulmonary embolism considered as low risk can be treated successfully as outpatients, according to a research letter by Dr. Margaret Fang and her associates.
Of nearly 5,000 patients included in the study, 494 were discharged from emergency departments. The proportion of PE patients discharged increased from 5.6% in 2004 to 11.1% in 2010. Just under 19% of those discharged visited the ED within 30 days, and 7.9% were hospitalized. Eleven patients were diagnosed with hemorrhage within 30 days, and there were two deaths within 90 days.
“Although still representing relatively few patients with PE, the proportion of discharges from ED settings nearly doubled during the 7-year study. Shifting appropriate patients to outpatient treatment may have benefits in terms of improved quality of life, enhanced physical and social functioning, and reduced costs of medical care,” the investigators said.

Fatal opioid overdoses down dramatically since 2010
Two changes in the pharmaceutical market in late 2010 dramatically reversed the alarming rise in fatal opioid overdoses that occurred during the preceding decade, according to a report published online April 20 in JAMA Internal Medicine.
Overdose deaths attributed to prescription opioids quadrupled in the U.S. between 1999 and 2010, in parallel with rapidly expanding sales of the drugs. Two changes in the pharmaceutical market were undertaken to address these unrelenting increases: replacing the standard formulation of OxyContin with an abuse-deterrent formulation (resistant to crushing and dissolving the tablets for ingestion, snorting, or injection) and withdrawing propoxyphene from sale, wrote Dr. Marc R. Larochelle of Harvard Pilgrim Health Care Institute and the department of population medicine, Harvard, both in Boston, and his associates.
To assess the impact of these 2 interventions, the investigators examined hospitalizations for prescription opioids as well as dispensing patterns using an insurance database covering adults in all 50 states. The data comprised 31,316,598 patients aged 18-64 who were enrolled in a commercial health plan between 2003 and 2012. There were 12,164 overdoses attributed to prescription opioids during the study period.
The “sudden, substantial, and sustained decreases” in the dispensing of prescription opioids at the end of 2010 was associated with parallel declines in fatal overdoses, which dropped by 19% in 2011 and by a further 20% in 2012. “Extrapolating our estimates at 2 years to the 124 million commercially insured U.S. residents aged 18-64 years, there would be 5,456 fewer prescription opioid overdoses . . . annually,” Dr. Larochelle and his associates said (JAMA Intern. Med. 2015 April 20 [doi:10.1001/jamainternmed.2015.0914]).
“This is the first study to demonstrate that a decrease in opioid supply is associated with a decrease in overall prescription opioid overdose,” they noted. “Our results have significant implications for policymakers and health care professionals grappling with the epidemic of opioid abuse and overdose.”
The findings by Larochelle et al highlight the critical importance of one public health lever: controlling the market supply of opioids.
Another effective intervention is to promote judicious opioid prescribing: favoring nonopioid or nonpharmacologic approaches to pain management and, when opioids are necessary, prescribing the lowest possible dose for the shortest amount of time necessary to control pain. Oher promising public health strategies include prescription drug monitoring programs and the regulation of pain clinics.

Larochelle of Harvard Pilgrim Health Care Institute and the department of population medicine, Harvard, both in Boston, and his associates.
To assess the impact of these 2 interventions, the investigators examined hospitalizations for prescription opioids as well as dispensing patterns using an insurance database covering adults in all 50 states. The data comprised 31,316,598 patients aged 18-64 who were enrolled in a commercial health plan between 2003 and 2012. There were 12,164 overdoses attributed to prescription opioids during the study period.
The “sudden, substantial, and sustained decreases” in the dispensing of prescription opioids at the end of 2010 was associated with parallel declines in fatal overdoses, which dropped by 19% in 2011 and by a further 20% in 2012. “Extrapolating our estimates at 2 years to the 124 million commercially insured U.S. residents aged 18-64 years, there would be 5,456 fewer prescription opioid overdoses . . . annually,” Dr. Larochelle and his associates said (JAMA Intern. Med. 2015 April 20 [doi:10.1001/jamainternmed.2015.0914]).
“This is the first study to demonstrate that a decrease in opioid supply is associated with a decrease in overall prescription opioid overdose,” they noted. “Our results have significant implications for policymakers and health care professionals grappling with the epidemic of opioid abuse and overdose.”
Two changes in the pharmaceutical market in late 2010 dramatically reversed the alarming rise in fatal opioid overdoses that occurred during the preceding decade, according to a report published online April 20 in JAMA Internal Medicine.

PHILADELPHIA—Cytotoxic T lymphocytes designed to target Epstein-Barr virus (EBV-CTLs) can elicit durable responses in patients
with EBV–associated lymphoproliferative disorder (EBV-LPD), according to data presented at the AACRAnnual Meeting 2015.
Results from two trials showed that EBV-CTLs derived from a patient’s transplant donor could produce a response rate of 62%, and EBV-CTLs derived from third-party donors could produce a response rate of 61%.
Study investigators noted that, with the achievement of complete response (CR), remission proved durable. And, unlike with chemotherapy, partial responses (PRs) to EBV-CTLs were durable as well.
The team presented these results as abstract CT107.*
“The purpose of our clinical trials was to see if giving T cells from a normal-immune individual that were expanded in culture and stimulated to respond to multiple proteins from the Epstein-Barr virus could provide a safe and effective treatment,” said Richard J. O’Reilly, MD, of Memorial Sloan Kettering Cancer Center in New York.
“The good news from our two clinical trials is that EBV-CTLs generated from either the patient’s transplant donor or from the bank of normal donor T cells developed at Memorial Sloan Kettering put aggressive EBV-LPD that had failed to respond to rituximab into long-lasting remission in more than 60% of patients.”
In the first trial, 26 patients with EBV-LPD received EBV-CTLs generated from their transplant donor. Thirteen of these patients had previously received rituximab, and 16 had high-risk disease.
Thirteen patients in this trial received HLA-matched, EBV-CTLs from the Memorial Sloan Kettering Cancer Center bank of EBV-CTLs generated from third-party, healthy donors. All 13 patients had high-risk disease, and 12 had received prior rituximab.
Dr O’Reilly noted that good results were observed with EBV-CTLs from both sources in this trial. And because EBV-CTLs from the bank are available immediately, he and his team used only EBV-CTLs from the bank when treating the 18 patients enrolled in the second trial.
Among the 39 patients enrolled in the first trial, 23 had a CR, none had a PR, and 2 had stable disease.
For patients who received EBV-CTLs from their primary donor, the combined rate of CR and PR was 62% (16 CRs). For patients who received third-party EBV-CTLs, the combined rate of CR and PR was 54% (7 CRs).
Sixteen of the patients who achieved a CR are still doing well, Dr O’Reilly said. Eight of these patients are alive more than 5 years after receiving EBV-CTLs, and 1 is alive more than 10 years after treatment.
Among the 18 patients enrolled in the second trial, 9 had a CR, 3 had a PR, and 1 had stable disease. The combined rate of CR and PR was 67%.
All of the patients who achieved a CR in this trial continue to do well, and the investigators will be following them long-term, Dr O’Reilly said.
He also noted that toxicities with EBV-CTLs were minimal, and there were no treatment-related deaths. None of the patients developed cytokine release syndrome or graft-vs-host disease requiring systemic therapy.
“The EBV-CTLs work well for the majority of recipients,” Dr O’Reilly said. “However, the responses became clinically evident only after the T cells expanded in vivo, which took about 7 to 14 days. We are rigorously pursuing the development of biomarkers or other tests to predict response earlier.”
Memorial Sloan Kettering Cancer Center has entered into an option agreement with Atara Biotherapeutics to further develop EBV-CTLs for clinical use. However, the data presented at AACR were accrued prior to that agreement.
Last month, the US Food and Drug Administration granted breakthrough therapy designation to EBV-CTLs generated from third-party donors for the treatment of patients with rituximab-refractory EBV-LPD.

New mAb can overcome resistance to other mAbs

A newly developed monoclonal antibody (mAb) can reverse resistance to other mAbs in chronic lymphocytic leukemia (CLL) and mantle cell lymphoma (MCL), according to research published in Cancer Cell.
Investigators found that some cancer cells draw mAbs inside themselves, making them invisible to immune cells.
But a mAb called BI-1206 can prevent this process and enhance cancer killing by binding to a molecule called FcγRIIB.
In preclinical experiments, BI-1206 was able to overcome resistance to mAbs such as rituximab.
“With more monoclonal antibody treatments being developed, there is an urgent need to understand how tumors become resistant to them and develop ways to overcome it,” said study author Mark Cragg, PhD, of the University of Southampton in the UK.
“Not only does BI-1206 appear to be able to reverse resistance to a range of monoclonal antibodies, it is also effective at directly killing cancer cells itself.”
In the Cancer Cell paper, BI-1206 is referred to as 6G11. The investigators found that 6G11 can block rituximab internalization and has “potent antitumor activity” in vitro. 6G11 was also well-tolerated and did not prompt cytokine storm.
In a mouse model of CLL, 6G11 enhanced rituximab-mediated depletion of primary CLL cells and improved responses when compared to rituximab alone.
In mice engrafted with cells from patients with CLL that was refractory to rituximab, ofatumumab, and/or alemtuzumab, 6G11 alone depleted CLL cells but did not improve overall response rates compared to rituximab alone. However, 6G11 in combination with rituximab did improve overall response rates compared to rituximab alone.
In a mouse model of MCL, neither 6G11 nor rituximab alone improved long-term survival. However, 30% of mice treated with both drugs survived tumor-free out to 100 days.
Combining 6G11 with obinutuzumab significantly improved splenic tumor cell depletion in mice with CLL. And more than 90% of mice that received 6G11 and alemtuzumab had a complete response to the treatment.
The investigators said these data suggest 6G11 can overcome mAb resistance for multiple targets. They said the drug will be tested in patients with CLL and non-Hodgkin lymphoma in an early stage clinical trial.
