Long-term entecavir looks safe, effective in HBV
For patients with chronic hepatitis B virus (HBV) infection, up to 10 years of treatment with entecavir was safe and produced a superior rate of sustained virologic response, compared with other HBV nucleoside or nucleotide analogues in a global randomized clinical trial.
Virologic responses were confirmed and maintained in 80% of entecavir patients and 61% of patients who received other therapies, said Jin-Lin Hou, MD, of Southern Medical University in Guangzhou, China, and associates. Regardless of which treatment patients received, a sustained virologic response was associated with a significantly lower rate of liver-related hepatitis B virus (HBV) disease progression and hepatocellular carcinoma. Rates of serious treatment-related adverse events were 0.2% in the entecavir arm and 0.8% in the nonentecavir arm. Moreover, the primary outcome of time-to-adjudicated clinical outcome events “showed that entecavir treatment, compared with nonentecavir, was not associated with an increased risk of malignant neoplasms, including hepatocellular carcinoma, nonhepatocellular carcinoma malignancies, and overall malignancies,” they wrote in Clinical Gastroenterology and Hepatology.
Entecavir is approved for the treatment of adults with chronic HBV infection, and its long-term use has been linked to the regression of hepatic fibrosis and cirrhosis. In treatment-naive patients, genotypic resistance and virologic breakthrough are rare even after up to 5 years of entecavir therapy. Although human studies have not linked this treatment duration with an increased risk of adverse events, murine studies have identified benign and malignant tumors of the brain, lung, and liver in entecavir-treated mice and rats. “With the exception of lung tumors, which were limited to male mice, rodent tumors occurred only at entecavir exposures [that were] significantly higher than those achieved in human beings with standard approved doses,” the researchers wrote.
For the trial, they assigned more than 12,000 patients with chronic HBV infection to receive long-term treatment with entecavir or investigators’ choice of another HBV nucleoside or nucleotide analogue. Patients were from 229 centers in Asia, Europe, and North and South America, and a total of 6,216 received entecavir, while 6,162 received another therapy.
Compared with other HBV nucleoside and nucleotide analogues, long-term treatment with entecavir “provided a high margin of safety” and was not tied to higher rates of liver or nonliver malignancies, the researchers found. The carcinogenicity of entecavir in rodents did not appear to extend to humans. Furthermore, among 5,305 trial participants in China, a sustained virologic response was associated with a clinically and statistically significant reduction in the risk of liver-related HBV disease progression (hazard ratio, 0.09; 95% CI, 0.04-0.22) and hepatocellular carcinoma (HR, 0.03; 95% CI, 0.009-0.113).
The results confirm the appropriateness of long-term entecavir therapy for chronic HBV infection, as recommended by current guidelines, Dr. Hou and associates concluded. However, patients in this trial were relatively young, with a median age of only 39 years. Therefore, the risk of entecavir-associated malignancies in older age cohorts could not be evaluated.
Bristol-Myers Squibb designed the study, performed statistical analyses, and funded the study and manuscript preparation. The Ministry of Science and Technology of China and the Local Innovative and Research Teams Project of Guangdong Pearl River Talents Program provided partial support. Dr. Hou disclosed grants and personal fees from Bristol-Myers Squibb, GlaxoSmithKline, and Novartis.

PACT-HF: Transitional care derives no overall benefit
Women respond more to intervention
PHILADELPHIA – A clinical trial of a program that transitions heart failure patients after they’re discharged from the hospital didn’t result in any appreciable improvement in all-cause death, readmissions or emergency department visits after 6 months overall, but it did show that women responded more favorably than men.
Harriette G.C. Van Spall, MD, MPH, reported 6-month results of the Patient-Centered Transitional Care Services in Heart Failure (PACT-HF) trial of 2,494 HF patients at 10 hospitals in Ontario during February 2015 to March 2016. They were randomized to the care-transition program or usual care. The findings, she said at the American Heart Association scientific sessions, “highlight the gap between efficacy that’s often demonstrated in mechanistic clinical trials and effectiveness when we aim to implement these results in real-world settings.” Three-month PACT-HF results were reported previously (JAMA. 2019 Feb 26;321:753-61).
The transitional-care model consisted of a comprehensive needs assessment by a nurse who also provided self-care education, a patient-centered discharge summary, and follow-up with a family physician within 7 days of discharge, which Dr. Van Spall noted “is not current practice in our health care system.”
Patients deemed high risk for readmission or death also received nurse home visits and scheduled visits to a multidisciplinary heart function clinic within 2-4 weeks of discharge and continuing as long as clinically suitable, said Dr. Van Spall, a principal investigator at the Population Health Research Institute, Hamilton, Ont., and assistant professor in cardiology at McMaster University in Hamilton.
The trial found no difference between the intervention and usual-care groups in the two composite endpoints at 6 months, Dr. Van Spall said: all-cause death, readmissions, or ED visits (63.1% and 64.5%, respectively; P = .50); or all-cause readmissions or ED visits (60.8% and 62.4%; P = .36).
“Despite the mutual overall clinical outcomes, we noted specific differences in response to treatment,” she said. With regard to the composite endpoint that included all-cause death, “Men had an attenuated response to the treatment with a hazard ratio of 1.05 (95% confidence interval, 0.87-1.26), whereas women had a hazard ratio of 0.85 (95% CI, 0.71-1.03), demonstrating that women have more of a treatment response to this health care service,” she said.
In men, rates for the first primary composite outcome were 66.3% and 64.1% in the intervention and usual-care groups, whereas in women those rates were 59.9% and 64.8% (P = .04 for sex interaction).
In the second composite endpoint, all-cause readmission or ED visit, “again, men had an attenuated response” with a HR of 1.03, whereas women had a HR of 0.83. Results were similar to those for the first primary composite outcome: 63.4% and 61.7% for intervention and usual care in men and 57.7% and 63% in women (P = .03 for sex interaction).
In putting the findings into context, Dr. Van Spall said tailoring services to risk in HF patients may be fraught with pitfalls. “We delivered intensive services to those patients at high risk of readmission or death, but it is quite possible they are the least likely to derive benefit by virtue of their advanced heart failure,” she said. “It may be that more benefit would have been derived had we chosen low- or moderate-risk patients to receive the intervention.”
She also said the sex-specific outcomes must be interpreted with caution. “But they do give us pause to consider that services could be titrated more effectively if delivered to patients who are more likely to derive benefit,” Dr. Van Spall said. The finding that women derived more of a benefit is in line with other prospective and observational studies that have found that women have a higher sense of self-care, self-efficacy, and confidence in managing their own health care needs than men.
Dr. Van Spall has no financial relationships to disclose.

REPORTING FROM AHA 2019
Adolescent alcohol, opioid misuse linked to risky behaviors
Binge drinking and misuse of opioids led to risky behavior during adolescence, two studies from the journal Pediatrics highlighted. And the binge drinking in high school may predict risky driving behaviors up to 4 years after high school.
Federico E. Vaca, MD, of the developmental neurocognitive driving simulation research center at Yale University, New Haven, Conn., and colleagues examined the associations between risky driving behaviors and binge drinking of 2,785 adolescents in the nationally representative, longitudinal NEXT Generation Health Study. The researchers studied the effects of binge drinking on driving while impaired (DWI), riding with an impaired driver (RWI), blackouts, extreme binge drinking, and risky driving.
The adolescents were studied across seven waves, with Wave 1 beginning in the 2009-2010 school year (10th grade; mean age, 16 years), and data extended up to 4 years after high school. Of all adolescents enrolled, 91% completed Wave 1, 88% completed Wave 2, 86% completed Wave 3 (12th grade), 78% completed Wave 4, 79% completed Wave 5, 84% completed Wave 6, and 83% completed Wave 7 (4 years after leaving high school) of the study.
High school binge drinking predicts later risky behavior
About one-quarter of adolescents reported binge drinking in Waves 1-3, with an incidence of 27% in Wave 1, 24% in Wave 2, and 27% in Wave 3. Adolescents who reported binge drinking in Wave 3 had a higher likelihood of DWI in subsequent waves, with nearly six times higher odds in Wave 5 and more than twice as likely in Wave 7, researchers said. Binge drinking in Wave 3 also was associated with greater than four times higher odds of RWI in Wave 4, and more than two and a half times higher odds of RWI in Wave 7. Among adolescents who reported binge drinking across 3 years in high school, there was a higher likelihood of extreme binge drinking in Wave 7, and higher likelihood of risky driving after graduating.
Impact of parental knowledge of drinking
in some waves. Father monitoring knowledge of drinking in Waves 1-3 lowered the odds of DWI by 30% in Wave 5 and 20% in Wave 6, while also lowering the odds of RWI in Wave 4 and Wave 7 by 20%.
Mother knowledge of drinking in Waves 1-3 was associated with 60% lower odds of DWI in Wave 4, but did not lower odds in any wave for RWI.
Overall, parental support for not drinking lowered odds for DWI by 40% in Waves 4 and 5, and by 30% in Wave 7 while also lowering odds of RWI in Wave 4 by 20%.
The results are consistent with other studies examining risky driving behavior and binge drinking in adolescent populations, but researchers noted that “to an important but limited extent, parental practices while the teenager is in high school may protect against DWI, RWI, and blackouts as adolescents move into early adulthood.”
“Our findings are relevant to prevention programs that seek to incorporate alcohol screening with intentional inquiry about binge drinking. Moreover, our results may be instructive to programs that seek to leverage facets of parental practices to reduce health-risk contexts for youth,” Dr. Vaca and colleagues concluded. “Such prevention activities coupled with strengthening of policies and practices reducing adolescents’ access to alcohol could reduce later major alcohol-related health-risk behaviors and their consequences.”
Opioid misuse and risky behavior
In a second study, Devika Bhatia, MD, of the University of Colorado at Denver, Aurora, and colleagues examined opioid misuse in a nationally-representative sample of 14,765 adolescents from the Centers for Disease Control and Prevention’s 2017 Youth Risk Behavior Surveillance Survey. The researchers measured opioid misuse by categorizing adolescents into groups based on whether they had ever misused prescription opioids and whether they had engaged in risky driving behavior, violent behavior, risky sexual behavior, had a history of substance abuse, or attempted suicide.
Dr. Bhatia and colleagues found 14% of adolescents in the study reported misusing opioids, with an overrepresentation of 17-year-old and 18-year-old participants reporting opioid misuse (P less than .0001). there were no statistically significant difference between those who misused opioids and those who did not in terms of race, ethnicity, or sex.
Those adolescents who reported misusing opioids were 2.8 times more likely to not use a seatbelt; were 2.8 times more likely to have RWI; were 5.8 times more likely to have DWI; or 2.3 times more likely to have texted or emailed while driving. In each of these cases, P was less than .0001.
Adolescents who misused opioids also had significantly increased odds of engaging in risky sexual behaviors such as having sex before 13 years (3.9 times); having sex with four or more partners (4.8 times); using substances before sex (3.6 times); and not using a condom before sex (2.0 times). In each of these cases, P was less than .0001.
Additionally, adolescents in this category were between 5.4 times and 22.3 times more likely to use other substances (P less than .0001 for 10 variables); 4.9 times more likely to have attempted suicide (P less than .0001); or more likely to have engaged in violent behavior such as getting into physical fights (4.0 times), carrying a weapon (3.4 times) or a gun (5.1 times) within the last 30 days. In the four latter cases, P was less than .0001.
“With the ongoing opioid epidemic, pediatricians and child psychiatrists are likely to be more attuned to opioid misuse in their patients,” Dr. Bhatia and colleagues concluded. “If youth are screening positive for opioid misuse, pediatricians, nurses, social workers, child psychiatrists, and other providers assessing adolescents may have a new, broad range of other risky behaviors for which to screen regardless of the direction of the association.”
Substance use screening for treating substance use disorder traditionally has been is provided by a specialist, Jessica A. Kulak, PhD, MPH, said in an interview. “However, integration of care services may help to change societal norms around problematic substance use – both by decreasing stigma associated with substance use, as well as increasing clinicians’ preparedness, knowledge, and confidence in preventing and intervening on adolescents’ substance experimentation and use.” She recommended that clinicians in primary care improve their training by using the Substance Abuse and Mental Health Services Administration’s Screening, Brief Intervention, and Referral to Treatment program, which is available as a free online course.
Confidentiality is important in adolescent health, said Dr. Kulak, who is an assistant professor in the department of health, nutrition, and dietetics at State University of New York at Buffalo. “When discussing sensitive topics, such as binge drinking and opioid misuse, adolescents may fear that these or other risky activities may be disclosed to parents or law enforcement officials. Therefore, adolescent health providers should be aware of local, state, and federal laws pertaining to the confidentiality of minors.”
She added, “adolescents are often susceptible to others’ influences, so having open communication and support from a trusted adult – be it a parent or clinician – may also be protective against risky behaviors.”
The study by Vaca et al. was funded by the National Institutes of Health with support from the Intramural Research Program of the Eunice Kennedy Shriver National Institute of Child Health and Human Development; the National Heart, Lung, and Blood Institute; the National Institute on Alcohol Abuse and Alcoholism; the National Institute on Drug Abuse; and the Maternal and Child Health Bureau of the Health Resources and Services Administration. The study by Bhatia et al. had no external funding. The authors from both studies reported no relevant financial disclosures. Dr. Kulak said she had no financial disclosures or other conflicts of interest.

These newly published reports indicate the high prevalence of risky behaviors and their associations – cross-sectionally and longitudinally – with major threats to adolescent health – so asking about alcohol use, opioid misuse, and associated health risks is truly “in the lane” of clinicians, school professionals, and parents who see and care about adolescents.
At this point, I think it’s incontrovertible that clinicians should screen adolescents to learn about their physical, emotional, and behavioral health. And they should seek opportunities for professional training, skills development, and expansion of their professional networks so they are able to address – individually or collaboratively via referrals – the behavioral and psychosocial health risks of their patients.
The good news is that there is growing awareness of the importance of using validated screening tools to identify patient behavioral health risks – including those pertaining to adolescent and young adult alcohol use and opioid misuse. “Best practice” dictates that screening approaches rely on asking questions using structured tools; intuition and “just winging it” are not effective or reliable for identifying patient behavior. Forward-looking clinics and practices could be asking patients to report about health behaviors in the waiting room (on a computer tablet, for example), or even remotely (using a secure app or data collection tool) in advance of a visit. Asking should be periodic – since behaviors can change fairly rapidly among young people. The benefit is that patient-reported information can be processed in advance to cue clinician follow-up and intervention. And youth tend to share more about their behaviors when they are asked electronically, rather than face to face. Intelligent screens can provide near real-time estimation of risk – to support in-office brief intervention tailored to the risk level of a young person or to trigger follow-up.
These studies indicate that binge alcohol use and misuse of prescription opioids among adolescents are real, pervasive, and deserving of our considered attention. There is no magic bullet. However busy clinicians may have a significant role to play in identifying and addressing these problems.

The good news is that there is growing awareness of the importance of using validated screening tools to identify patient behavioral health risks – including those pertaining to adolescent and young adult alcohol use and opioid misuse. “Best practice” dictates that screening approaches rely on asking questions using structured tools; intuition and “just winging it” are not effective or reliable for identifying patient behavior. Forward-looking clinics and practices could be asking patients to report about health behaviors in the waiting room (on a computer tablet, for example), or even remotely (using a secure app or data collection tool) in advance of a visit. Asking should be periodic – since behaviors can change fairly rapidly among young people. The benefit is that patient-reported information can be processed in advance to cue clinician follow-up and intervention. And youth tend to share more about their behaviors when they are asked electronically, rather than face to face. Intelligent screens can provide near real-time estimation of risk – to support in-office brief intervention tailored to the risk level of a young person or to trigger follow-up.
These studies indicate that binge alcohol use and misuse of prescription opioids among adolescents are real, pervasive, and deserving of our considered attention. There is no magic bullet. However busy clinicians may have a significant role to play in identifying and addressing these problems.

These newly published reports indicate the high prevalence of risky behaviors and their associations – cross-sectionally and longitudinally – with major threats to adolescent health – so asking about alcohol use, opioid misuse, and associated health risks is truly “in the lane” of clinicians, school professionals, and parents who see and care about adolescents.

Binge drinking and misuse of opioids led to risky behavior during adolescence, two studies from the journal Pediatrics highlighted. And the binge drinking in high school may predict risky driving behaviors up to 4 years after high school.
Federico E. Vaca, MD, of the developmental neurocognitive driving simulation research center at Yale University, New Haven, Conn., and colleagues examined the associations between risky driving behaviors and binge drinking of 2,785 adolescents in the nationally representative, longitudinal NEXT Generation Health Study. The researchers studied the effects of binge drinking on driving while impaired (DWI), riding with an impaired driver (RWI), blackouts, extreme binge drinking, and risky driving.
The adolescents were studied across seven waves, with Wave 1 beginning in the 2009-2010 school year (10th grade; mean age, 16 years), and data extended up to 4 years after high school. Of all adolescents enrolled, 91% completed Wave 1, 88% completed Wave 2, 86% completed Wave 3 (12th grade), 78% completed Wave 4, 79% completed Wave 5, 84% completed Wave 6, and 83% completed Wave 7 (4 years after leaving high school) of the study.
High school binge drinking predicts later risky behavior
About one-quarter of adolescents reported binge drinking in Waves 1-3, with an incidence of 27% in Wave 1, 24% in Wave 2, and 27% in Wave 3. Adolescents who reported binge drinking in Wave 3 had a higher likelihood of DWI in subsequent waves, with nearly six times higher odds in Wave 5 and more than twice as likely in Wave 7, researchers said. Binge drinking in Wave 3 also was associated with greater than four times higher odds of RWI in Wave 4, and more than two and a half times higher odds of RWI in Wave 7. Among adolescents who reported binge drinking across 3 years in high school, there was a higher likelihood of extreme binge drinking in Wave 7, and higher likelihood of risky driving after graduating.
Impact of parental knowledge of drinking
in some waves. Father monitoring knowledge of drinking in Waves 1-3 lowered the odds of DWI by 30% in Wave 5 and 20% in Wave 6, while also lowering the odds of RWI in Wave 4 and Wave 7 by 20%.
Mother knowledge of drinking in Waves 1-3 was associated with 60% lower odds of DWI in Wave 4, but did not lower odds in any wave for RWI.
Overall, parental support for not drinking lowered odds for DWI by 40% in Waves 4 and 5, and by 30% in Wave 7 while also lowering odds of RWI in Wave 4 by 20%.
The results are consistent with other studies examining risky driving behavior and binge drinking in adolescent populations, but researchers noted that “to an important but limited extent, parental practices while the teenager is in high school may protect against DWI, RWI, and blackouts as adolescents move into early adulthood.”
“Our findings are relevant to prevention programs that seek to incorporate alcohol screening with intentional inquiry about binge drinking. Moreover, our results may be instructive to programs that seek to leverage facets of parental practices to reduce health-risk contexts for youth,” Dr. Vaca and colleagues concluded. “Such prevention activities coupled with strengthening of policies and practices reducing adolescents’ access to alcohol could reduce later major alcohol-related health-risk behaviors and their consequences.”
Opioid misuse and risky behavior
In a second study, Devika Bhatia, MD, of the University of Colorado at Denver, Aurora, and colleagues examined opioid misuse in a nationally-representative sample of 14,765 adolescents from the Centers for Disease Control and Prevention’s 2017 Youth Risk Behavior Surveillance Survey. The researchers measured opioid misuse by categorizing adolescents into groups based on whether they had ever misused prescription opioids and whether they had engaged in risky driving behavior, violent behavior, risky sexual behavior, had a history of substance abuse, or attempted suicide.
Dr. Bhatia and colleagues found 14% of adolescents in the study reported misusing opioids, with an overrepresentation of 17-year-old and 18-year-old participants reporting opioid misuse (P less than .0001). there were no statistically significant difference between those who misused opioids and those who did not in terms of race, ethnicity, or sex.
Those adolescents who reported misusing opioids were 2.8 times more likely to not use a seatbelt; were 2.8 times more likely to have RWI; were 5.8 times more likely to have DWI; or 2.3 times more likely to have texted or emailed while driving. In each of these cases, P was less than .0001.
Adolescents who misused opioids also had significantly increased odds of engaging in risky sexual behaviors such as having sex before 13 years (3.9 times); having sex with four or more partners (4.8 times); using substances before sex (3.6 times); and not using a condom before sex (2.0 times). In each of these cases, P was less than .0001.
Additionally, adolescents in this category were between 5.4 times and 22.3 times more likely to use other substances (P less than .0001 for 10 variables); 4.9 times more likely to have attempted suicide (P less than .0001); or more likely to have engaged in violent behavior such as getting into physical fights (4.0 times), carrying a weapon (3.4 times) or a gun (5.1 times) within the last 30 days. In the four latter cases, P was less than .0001.
“With the ongoing opioid epidemic, pediatricians and child psychiatrists are likely to be more attuned to opioid misuse in their patients,” Dr. Bhatia and colleagues concluded. “If youth are screening positive for opioid misuse, pediatricians, nurses, social workers, child psychiatrists, and other providers assessing adolescents may have a new, broad range of other risky behaviors for which to screen regardless of the direction of the association.”
Substance use screening for treating substance use disorder traditionally has been is provided by a specialist, Jessica A. Kulak, PhD, MPH, said in an interview. “However, integration of care services may help to change societal norms around problematic substance use – both by decreasing stigma associated with substance use, as well as increasing clinicians’ preparedness, knowledge, and confidence in preventing and intervening on adolescents’ substance experimentation and use.” She recommended that clinicians in primary care improve their training by using the Substance Abuse and Mental Health Services Administration’s Screening, Brief Intervention, and Referral to Treatment program, which is available as a free online course.
Confidentiality is important in adolescent health, said Dr. Kulak, who is an assistant professor in the department of health, nutrition, and dietetics at State University of New York at Buffalo. “When discussing sensitive topics, such as binge drinking and opioid misuse, adolescents may fear that these or other risky activities may be disclosed to parents or law enforcement officials. Therefore, adolescent health providers should be aware of local, state, and federal laws pertaining to the confidentiality of minors.”
She added, “adolescents are often susceptible to others’ influences, so having open communication and support from a trusted adult – be it a parent or clinician – may also be protective against risky behaviors.”
The study by Vaca et al. was funded by the National Institutes of Health with support from the Intramural Research Program of the Eunice Kennedy Shriver National Institute of Child Health and Human Development; the National Heart, Lung, and Blood Institute; the National Institute on Alcohol Abuse and Alcoholism; the National Institute on Drug Abuse; and the Maternal and Child Health Bureau of the Health Resources and Services Administration. The study by Bhatia et al. had no external funding. The authors from both studies reported no relevant financial disclosures. Dr. Kulak said she had no financial disclosures or other conflicts of interest.

Adenotonsillectomy doesn’t improve cognitive function in preschoolers with OSA
according to a prospective study.
The study showed no significant difference in global IQ at 12 months between children who underwent adenotonsillectomy and those who did not. However, as expected, the adenotonsillectomy group did experience improvements in sleep.
Karen A. Waters, MBBS, PhD, of the Children’s Hospital at Westmead and the University of Sydney, and her colleagues reported these results in Pediatrics. There also was a related commentary.
The study enrolled 190 children (ages 3-5 years) with mild obstructive sleep apnea. Roughly half of patients (n = 99) were randomized to early adenotonsillectomy (within 2 months), and the other half (n = 91) were randomized to no adenotonsillectomy (12-month routine wait). There were 121 patients who had global IQ assessments at 12 months, as measured by the Woodcock Johnson III Brief Intellectual Ability (BIA) test. Of these patients, 61 were in the adenotonsillectomy group, and 60 were in the control group.
Both groups had improvements in BIA scores from baseline to 12 months, and the 12-month BIA score was not significantly different between the groups.
At baseline, the mean W score (task proficiency) for BIA was 448.36 in the adenotonsillectomy group and 451.3 in the control group. At 12 months, the scores were 465.46 and 463.12, respectively (P = .29).
“Intellectual ability scores improved in both groups over time with no effect attributable to the intervention [adenotonsillectomy],” Dr. Waters and her colleagues wrote.
However, patients in the adenotonsillectomy group did have greater improvements in sleep than patients in the control group, as assessed by polysomnogram and parent reports.
In the adenotonsillectomy group, the mean total sleep time was 469.2 minutes at baseline and 481.8 minutes at 12 months. In the control group, the mean total sleep time was 463.8 minutes at baseline and 475.3 minutes at 12 months. The adjusted mean difference was –2.12 (P less than .001).
According to parent reports, children in the adenotonsillectomy group were significantly less likely than those in the control group to have trouble sleeping at night at 12 months: 8% and 74%, respectively (P less than .001).
“Children randomly assigned to adenotonsillectomy did show greater improvement in polysomnography obstructive indices and parent-reported behavior but did not demonstrate a treatment-attributable improvement in cognitive function,” David O. Francis, MD, of University of Wisconsin–Madison, and Derek J. Lam, MD, of Oregon Health & Science University in Portland, wrote in a related commentary.
The commentators noted that these results are similar to those of the CHAT study, which showed no significant differences in Developmental Neuropsychological Assessment results between children (ages 5-9 years) who underwent adenotonsillectomy and those who did not (N Engl J Med. 2013 Jun 20;368[25]:2366-76).

FROM PEDIATRICS
Navitoclax may overcome ruxolitinib resistance in MF
ORLANDO – Adding navitoclax to ruxolitinib improved responses in a phase 2 trial of patients with uncontrolled myelofibrosis (MF) and prolonged exposure to ruxolitinib.
Navitoclax and ruxolitinib yielded “clinically meaningful” spleen responses, improved total symptom scores, and produced “encouraging” reductions in bone marrow fibrosis among patients with primary or secondary MF, according to Jacqueline S. Garcia, MD, of Dana-Farber Cancer Institute in Boston.
Dr. Garcia presented these results at the annual meeting of the American Society of Hematology.
Navitoclax binds with high affinity to BCL-XL, BCL-2, and BCL-W, Dr. Garcia noted. Preclinical research has shown that combining Janus kinase 2 (JAK2) inhibition with BCL-XL/BCL-2 inhibition has a synergistic cytotoxic effect on JAK2-mutated cells (Blood. 2009 Feb 12;113[7]:1522-5), and BCL-XL inhibition can overcome resistance to JAK2 inhibition (Cell Rep. 2013 Nov 27;5[4]:1047-59).
These findings led to the theory that combining navitoclax and ruxolitinib could overcome resistance to JAK2 inhibition in MF. The researchers tested this theory in a phase 2 trial (NCT03222609) of 34 MF patients.
The patients had primary MF (n = 16), post–polycythemia vera MF (n = 13), and post–essential thrombocythemia MF (n = 5). At baseline, their median age was 68 years (range 42-86 years), and 68% of them were men.
There were 33 patients with genetic testing results available. None of them were triple negative, 27 had JAK2 mutations, and 7 had CALR mutations. Roughly half of patients (n = 17) were classified as high molecular risk, with mutations in ASXL1, EZH2, IDH1/2, SRSF2, or U2AF1.
Treatment
All patients had received ruxolitinib for at least 12 weeks prior to their first dose of navitoclax. They had been receiving a stable dose of 10 mg or greater, twice daily, for at least 8 weeks. The median duration of prior ruxolitinib exposure was 21 months (range, 4-71 months).
On study, patients received navitoclax once daily plus the current stable dose of ruxolitinib (10 mg or greater twice daily). Navitoclax dosing started at 50 mg, but weekly dose escalation was allowed to a maximum daily dose of 300 mg. Treatment could continue until the loss of clinical benefit, unacceptable toxicity, or discontinuation.
There were 23 patients who received the maximum dose of navitoclax, and the median duration of navitoclax treatment was 330 days (range, 29-588 days). Of the 25 patients who started the study on a ruxolitinib dose higher than 10 mg twice daily, 22 had their dose reduced to 10 mg twice daily.
Nine patients discontinued study treatment – three due to adverse events, two due to progressive disease, and four for other reasons.
Efficacy
Navitoclax appears to overcome ruxolitinib resistance, Dr. Garcia said, citing improvements in spleen size, symptom scores, bone marrow fibrosis, white blood cell counts, and transfusion needs.
Thirty patients were evaluable for spleen response. At week 24, 30% had a spleen volume reduction of 35% or greater from baseline. At any time on study, 43% of patients had a spleen volume reduction of 35% or greater from baseline. More than half of patients (53%) had a resolution of palpable splenomegaly.
Eight of 32 patients (25%) had a reduction in bone marrow fibrosis, four with a one-grade reduction and four with a two-grade reduction.
Seventeen patients were evaluable for change in total symptom score. Eleven patients (65%) experienced a reduction in symptoms, and six (35%) had a 50% or greater reduction in symptoms. The median total symptom score was 12 (range, 0-30) at baseline and 7 (range, 0-23) at 24 weeks.
Patients had a significant reduction in white blood cells on study. The mean white blood cell reduction at week 24 was 25.8 x 109/L.
Patients’ hemoglobin levels remained stable over time, but a few patients had a decreased need for transfusions on study. Seven patients entered the study having received at least one unit of packed red blood cells in the prior 12 weeks. Four of them (57%) have had a transfusion-free period of at least 12 weeks on study.
Safety
“Navitoclax in combination with ruxolitinib appears to be well tolerated,” Dr. Garcia said.
She noted that treatment resulted in reduced platelet counts, but counts stabilized after 6-8 weeks. The mean platelet count was 232 x 109/L at baseline and 95 x 109/L at week 8.
In fact, the most common adverse event was thrombocytopenia, with any-grade thrombocytopenia occurring in 85% of patients and grade 3/4 occurring in 44%. One patient had grade 4 thrombocytopenia, but it was reversed by withholding treatment and subsequent dose modification.
Other common treatment-emergent adverse events were diarrhea (68%), fatigue (53%), nausea (35%), anemia (29%), dizziness (27%), confusion (27%), and vomiting (24%).
All 34 patients experienced at least one adverse event. Eight patients (24%) had serious adverse events, including anemia, pancytopenia, splenic infarction, upper abdominal pain, vomiting, chest pain, pneumonia, and abnormal liver function test.
One patient had a grade 5 adverse event – pneumonia – that was deemed unrelated to navitoclax.
This trial is sponsored by AbbVie. Dr. Garcia reported relationships with AbbVie, Genentech, and Pfizer.

ORLANDO – Adding navitoclax to ruxolitinib improved responses in a phase 2 trial of patients with uncontrolled myelofibrosis (MF) and prolonged exposure to ruxolitinib.
Navitoclax and ruxolitinib yielded “clinically meaningful” spleen responses, improved total symptom scores, and produced “encouraging” reductions in bone marrow fibrosis among patients with primary or secondary MF, according to Jacqueline S. Garcia, MD, of Dana-Farber Cancer Institute in Boston.
Dr. Garcia presented these results at the annual meeting of the American Society of Hematology.
Navitoclax binds with high affinity to BCL-XL, BCL-2, and BCL-W, Dr. Garcia noted. Preclinical research has shown that combining Janus kinase 2 (JAK2) inhibition with BCL-XL/BCL-2 inhibition has a synergistic cytotoxic effect on JAK2-mutated cells (Blood. 2009 Feb 12;113[7]:1522-5), and BCL-XL inhibition can overcome resistance to JAK2 inhibition (Cell Rep. 2013 Nov 27;5[4]:1047-59).
These findings led to the theory that combining navitoclax and ruxolitinib could overcome resistance to JAK2 inhibition in MF. The researchers tested this theory in a phase 2 trial (NCT03222609) of 34 MF patients.
The patients had primary MF (n = 16), post–polycythemia vera MF (n = 13), and post–essential thrombocythemia MF (n = 5). At baseline, their median age was 68 years (range 42-86 years), and 68% of them were men.
There were 33 patients with genetic testing results available. None of them were triple negative, 27 had JAK2 mutations, and 7 had CALR mutations. Roughly half of patients (n = 17) were classified as high molecular risk, with mutations in ASXL1, EZH2, IDH1/2, SRSF2, or U2AF1.
Treatment
All patients had received ruxolitinib for at least 12 weeks prior to their first dose of navitoclax. They had been receiving a stable dose of 10 mg or greater, twice daily, for at least 8 weeks. The median duration of prior ruxolitinib exposure was 21 months (range, 4-71 months).
On study, patients received navitoclax once daily plus the current stable dose of ruxolitinib (10 mg or greater twice daily). Navitoclax dosing started at 50 mg, but weekly dose escalation was allowed to a maximum daily dose of 300 mg. Treatment could continue until the loss of clinical benefit, unacceptable toxicity, or discontinuation.
There were 23 patients who received the maximum dose of navitoclax, and the median duration of navitoclax treatment was 330 days (range, 29-588 days). Of the 25 patients who started the study on a ruxolitinib dose higher than 10 mg twice daily, 22 had their dose reduced to 10 mg twice daily.
Nine patients discontinued study treatment – three due to adverse events, two due to progressive disease, and four for other reasons.

Scientific Roundtable Focuses Efforts on Leiomyosarcoma Research
Research clinicians from the US and abroad participated in a scientific research roundtable this past September to establish the most important issues facing leiomyosarcoma (LMS) research and clinical trials. The workshop, expected to be an annual event, is a joint effort of the National Leiomyosarcoma Foundation (NLMSF) and Sarcoma Patients EuroNet (SPAEN).
The roundtable’s mission is to bring together sarcoma experts for a meeting dedicated to LMS, where participants discuss the present state of LMS and the continued challenges of diagnosis and treatment. Its goal is to develop working plans to close the gaps in LMS patient care and improve LMS patient-care protocols. They also advise the NLMSF on worthy and important research projects that deserve the foundation’s future funding efforts.
Plans for roundtable meetings in 2020 and 2021 are already underway. Between the annual meetings, workgroups continue to take steps toward addressing the issues identified by the roundtable. For more information on the roundtable and NLMSF, visit: https://nlmsf.org.

State of Hospital Medicine Survey plays key role in operational decision making
Results help establish hospitalist benchmarks
The Hospitalist recently spoke with Brian Schroeder, MHA, FACHE, FHM, assistant vice president, Hospital & Emergency Medicine, at Atrium Health Medical Group in Charlotte, N.C., to discuss his participation in the State of Hospital Medicine Survey, which is distributed every other year, and how he uses the resulting report to guide important operational decisions.
Please describe your current role.
At Carolinas Hospitalist Group, we have approximately 250 providers at nearly 20 care locations across North Carolina. Along with my specialty medical director, I am responsible for the strategic growth, program development, and financial performance for our practice.
How did you first become involved with the Society of Hospital Medicine?
When I first entered the hospital medicine world in 2008, I was looking for an organization that supported our specialty. My physician leaders at the time pointed me to SHM. Since the beginning of my time as a member, I have attended the Annual Conference each year, the SHM Leadership Academy, served on an SHM committee, and participate in SHM’s multisite Leaders group. Additionally, I have served as faculty at SHM’s annual conference for 3 years – and will be presenting for the third time at HM20.
Why is it important that people participate in the State of Hospital Medicine Survey?
Participation in the survey is key for establishing benchmarks for our specialty. The more people participate (from various arenas like private groups, health system employees, and vendors), the more accurate the data. Over the past 4 years, SHM has improved the submission process of survey data – especially for practices with multiple locations.
How has the data in the report impacted important business decisions for your group?
We rely heavily on the investment/provider benchmark within the survey data. Over the years, as the investment/provider was decreasing nationally, our own investment/provider was increasing. Based on the survey, we were able to closely evaluate our staffing models at each location and determine the appropriate skill mix-to-volume ratio. Through turnover and growth, we have strategically hired advanced practice providers to align our investment more closely with the benchmark. Over the past 2 years, our investment/provider metric has decreased significantly. We were able to accomplish this while continuing to provide appropriate care to our patients. We also utilize the Report to monitor performance incentive metrics, staffing model trends, and encounter/provider ratios.
What would you tell people who are on the fence about participating in the survey – and ultimately, purchasing the finished product?
Do it! Our practice would never skip a submission year. The data produced from the survey helps us improve our clinical operations and maximize our financial affordability. The data also assists in defending staffing decisions and clinical operations change with senior leadership within the organization.
Don’t miss your chance to submit data that will build the latest snapshot of the hospital medicine specialty. The State of Hospital Medicine Survey is open now and runs through February 16, 2020. Learn more and register to participate at hospitalmedicine.org/survey.

Bimekizumab elevates psoriasis therapy
MADRID – Renowned dermatologic clinical trialist Kim A. Papp, MD, PhD, is known to pick his words carefully, and the word he uses to describe the quality of life improvement documented in psoriasis patients treated with the novel investigational humanized monoclonal antibody bimekizumab is “phenomenal.”
Dr. Papp was lead investigator in the previously reported phase 2b multicenter BE ABLE 1 trial, in which 250 patients with moderate to severe chronic plaque psoriasis were randomized double-blind to various doses of bimekizumab or placebo every 4 weeks for 12 weeks (J Am Acad Dermatol. 2018 Aug;79[2]:277-86.e10. doi: 10.1016/j.jaad.2018.03.037). He was also lead investigator in the 48-week phase 2b BE ABLE 2 extension study. He presented the 60-week quality-of-life BE ABLE 2 results for the first time at the annual congress of the European Academy of Dermatology and Venereology.
“Small numbers, but the results are nonetheless very compelling,” said Dr. Papp, president and founder of Probity Medical Research in Waterloo, Ont.
Bimekizumab is unique in that it selectively neutralizes both interleukin-17A and -17F, two closely related proinflammatory cytokines which, when upregulated, synergize with other proinflammatory cytokines to drive psoriasis and other immune-mediated inflammatory diseases. In contrast, secukinumab (Cosentyx) and ixekizumab (Taltz) specifically inhibit only IL-17A, and brodalumab (Siliq) targets the IL-17 receptor A. The bimekizumab clinical trials program – a work in progress – aims to demonstrate that dual neutralization of IL-17A and -17F provides a more complete therapeutic approach in psoriasis, with greater efficacy and fewer safety concerns than with current biologics, the dermatologist explained.
In BE ABLE 1, the primary endpoint of at least a 90% reduction in Psoriasis Area and Severity Index (PASI90) response was achieved at week 12 in 46%-79% of patients randomized to bimekizumab in dose-dependent fashion. Those PASI90 responses were maintained with additional treatment out to week 60 in BE ABLE 2 in 80%-100% of patients.
Dr. Papp’s focus at EADV 2019 was on the quality-of-life improvement achieved in bimekizumab-treated patients, a benefit not captured by PASI scores. For this purpose, he and coinvestigators turned to the Dermatology Life Quality Index (DLQI), measured in structured fashion every 4 weeks out to week 60.
“We often forget that even though we’re looking at the patient from the outside, what’s really important is how well they respond to our treatments internally. The DLQI is not a perfect tool, but it’s the best tool we have available. It gives us a fairly good survey of the various domains that affect patients’ day-to-day living,” he said.
In BE ABLE 1, the proportion of week-12 PASI90 responders achieving a DLQI of 0 or 1 – indicative of essentially no disease impact on quality of life – increased rapidly up until week 8. At week 12, 70%-100% of the PASI90 responders in the various treatment arms had a DLQI of 0 or 1. This quality-of-life improvement, like the PASI90 response, proved durable: When the week-12 PASI90 responders were assessed at week 60 in BE ABLE 2, 76%-93% of them had a DLQI of 0 or 1.
The improvements in quality of life correlated with clinical response. BE ABLE enrollees had an average PASI score of 19 at baseline.

MADRID – Renowned dermatologic clinical trialist Kim A. Papp, MD, PhD, is known to pick his words carefully, and the word he uses to describe the quality of life improvement documented in psoriasis patients treated with the novel investigational humanized monoclonal antibody bimekizumab is “phenomenal.”
Dr. Papp was lead investigator in the previously reported phase 2b multicenter BE ABLE 1 trial, in which 250 patients with moderate to severe chronic plaque psoriasis were randomized double-blind to various doses of bimekizumab or placebo every 4 weeks for 12 weeks (J Am Acad Dermatol. 2018 Aug;79[2]:277-86.e10. doi: 10.1016/j.jaad.2018.03.037). He was also lead investigator in the 48-week phase 2b BE ABLE 2 extension study. He presented the 60-week quality-of-life BE ABLE 2 results for the first time at the annual congress of the European Academy of Dermatology and Venereology.
“Small numbers, but the results are nonetheless very compelling,” said Dr. Papp, president and founder of Probity Medical Research in Waterloo, Ont.
Bimekizumab is unique in that it selectively neutralizes both interleukin-17A and -17F, two closely related proinflammatory cytokines which, when upregulated, synergize with other proinflammatory cytokines to drive psoriasis and other immune-mediated inflammatory diseases. In contrast, secukinumab (Cosentyx) and ixekizumab (Taltz) specifically inhibit only IL-17A, and brodalumab (Siliq) targets the IL-17 receptor A. The bimekizumab clinical trials program – a work in progress – aims to demonstrate that dual neutralization of IL-17A and -17F provides a more complete therapeutic approach in psoriasis, with greater efficacy and fewer safety concerns than with current biologics, the dermatologist explained.
In BE ABLE 1, the primary endpoint of at least a 90% reduction in Psoriasis Area and Severity Index (PASI90) response was achieved at week 12 in 46%-79% of patients randomized to bimekizumab in dose-dependent fashion. Those PASI90 responses were maintained with additional treatment out to week 60 in BE ABLE 2 in 80%-100% of patients.
Dr. Papp’s focus at EADV 2019 was on the quality-of-life improvement achieved in bimekizumab-treated patients, a benefit not captured by PASI scores. For this purpose, he and coinvestigators turned to the Dermatology Life Quality Index (DLQI), measured in structured fashion every 4 weeks out to week 60.
“We often forget that even though we’re looking at the patient from the outside, what’s really important is how well they respond to our treatments internally. The DLQI is not a perfect tool, but it’s the best tool we have available. It gives us a fairly good survey of the various domains that affect patients’ day-to-day living,” he said.
In BE ABLE 1, the proportion of week-12 PASI90 responders achieving a DLQI of 0 or 1 – indicative of essentially no disease impact on quality of life – increased rapidly up until week 8. At week 12, 70%-100% of the PASI90 responders in the various treatment arms had a DLQI of 0 or 1. This quality-of-life improvement, like the PASI90 response, proved durable: When the week-12 PASI90 responders were assessed at week 60 in BE ABLE 2, 76%-93% of them had a DLQI of 0 or 1.
The improvements in quality of life correlated with clinical response. BE ABLE enrollees had an average PASI score of 19 at baseline. Overall, 79% of those with an absolute PASI score of 0 at week 12 had a DLQI of 0 or 1 at that time, as did 95% of those with a PASI of 0 at week 60. A PASI of 1 was associated with a 77% likelihood of a DLQI of 0 or 1 at week 12 and an 82% rate at week 60.

REPORTING FROM THE EADV CONGRESS
Unique T cell populations pinpointed in hepatocellular carcinoma tissue
Hepatocellular carcinoma (HCC) tissue contains several unique populations of tumor infiltrating cells, including some exhausted effector T cells that regain normal function when treated with the immunotherapy drug nivolumab, according to researchers.
The unique populations of recently activated CD4+, CD8+, and CD4-CD8 double-negative cells identified in the tumors expressed specific activation markers and inhibitor receptors, according to investigators, who have published the results of their immune profiling analyses in Cellular and Molecular Gastroenterology and Hepatology.
“Importantly, these cells expressed markers of activation and tissue residence, possibly suggesting activation within the tumor,” said Daniela Di Blasi, PhD, and the others researchers, of the University of Basel in Switzerland.
A further look at tumor histology revealed an accumulation of those activated T cells in immune-inflamed HCC, according to the investigators, who added that enumeration of specific tumor-infiltrating lymphocytes could represent “a prognostic indicator of therapy responsiveness.”
However, they advised caution in interpreting the results to date: “We are aware that the analysis described here is based on a small number of patients and that validation of its prognostic value requires ad hoc prospective studies that include more patients,” they said in their report.
The researcher’s findings were based on analysis of HCC biopsies before and after treatment with the immune checkpoint inhibitor nivolumab, nontumor liver tissue biopsies, and peripheral blood samples from 36 patients, most of whom were male, and about half of whom had cirrhosis. Investigators used multiparametric flow cytometry to characterize expression of activation markers including CD137, CD150, and ICOS, among others, as well as expression of inhibitory receptors including TIGIT and PD1.
Compared with nonneoplastic liver tissue, tumor tissue was enriched with T cells expressing the activation marker CD137 and the inhibitory receptor ICOS, indicating that HCC tumor-infiltrating lymphocytes “are different from liver-resident T cells and might have immunologic relevance,” Dr. Di Blasi and coauthors said in their report.
Further analysis revealed several cell populations unique to HCC samples, the authors said, including CD4+ T cells coexpressing ICOS and TIGIT, which tended to accumulate in tumor tissue, compared with nontumor tissue and peripheral blood mononuclear cells. Those CD4+ tumor-infiltrating T cells were functionally impaired, they added, as shown by a lack of cytokine production.
Activated CD8+ T cells likewise preferentially accumulated in tumor tissue, and most of those tumor-infiltrating cells expressed CD38 and PD1. The presence of these proliferating and functional cells may contribute to local inflammation and antitumor response, according to the investigators, who also identified two unique populations of double-negative T cells, including some that expressed CD137, which they said was a marker of recent T-cell activation.
The investigators also looked at the presence of tumor-infiltrating lymphocytes correlated to the presence of mononuclear cell infiltrate in tumor tissue. They found that immune-inflamed tumors had significantly increased proliferation of unique CD4+, CD8+, and double-negative T cell populations.
Nivolumab treatment appeared to substantially reduce the proportion of impaired CD4+ T cells, while increasing the percentage of interferon gamma–producing CD38+ CD4+ T cells and also promoting enrichment of interferon gamma–producing CD38+ CD8+ cells. Those increases in release of interferon gamma may have a positive influence on antitumor immunity via modulation of immune and tumor cell functions, according to the investigators.
Not all immune-inflamed tumors responded to nivolumab treatment, suggesting that an immune-inflamed profile is “necessary but not sufficient” for clinical response to an anti-PD1 agent, noted Dr. Di Blasi and colleagues.
Taken together, the researchers said their investigations suggest the presence of unique populations of T cells that might be providing effective anti-tumor immunity.
“These studies set the point for the identification of the tumor antigens stimulating these T cells and their possible exploitation as immunotherapeutic targets in HCC,” they concluded in the report.
The study was supported by grants from the European Research Council and the Swiss Initiative in Systems Biology, among others. Dr. Di Blasi and coauthors disclosed no conflicts of interest.

Immunotherapy with checkpoint inhibitors has been suggested for the treatment of hepatocellular carcinoma (HCC) and finding relevant predictors of response to immunotherapy remains one of the most challenging tasks for solid gastrointestinal cancers such as HCC where efficiency of immune therapy suggests only a moderate response so far. Recently, two randomized phase 3 trials on checkpoint inhibitors in HCC, both first-line against sorafenib (Checkmate 459) as well as second-line against placebo (KEYNOTE-240), have failed to show an overall survival benefit despite clinical benefit in some patients and a manageable side effects profile. The study by Di Blasi et al. therefore provides important insights into the immune cell composition of tumor-infiltrating lymphocytes (TILs) in HCC. In this study it was possible to identify certain cell populations within TILs that resembled recently activated tumor-specific T cells that were in an exhausted state. It was possible to reinvigorate these exhausted cell clusters and to activate IFN-delta–producing T cells with the help of checkpoint inhibitor therapy in these patients. These data suggest that the enumeration of certain immune cell infiltrates may identify patients responding to checkpoint inhibitor therapy. Another important observation from this study was that not all immune-inflamed tumors identified by immunohistochemistry (or so-called “hot tumors”) responded to checkpoint inhibitor therapy and that more sophisticated analysis of the immune infiltrates with, e.g., flow cytometry or mass cytometry seems to be necessary to understand which patients respond. Different immune cell clusters have been suggested by other research groups and further research is needed to confirm this theory and to understand which of the proposed immune cell clusters and phenotypic profiles will prove most valuable in terms of prognosis for checkpoint inhibitor therapy in HCC.
