There is a higher prevalence of opioid prescribing and opioid-related overdose deaths concentrated in regions with mostly low-income, white residents, compared with regions with high income and the lowest proportion of white residents, according to a new analysis of data on people living in California.

The findings of this study provide further evidence that the opioid epidemic affects a large proportion of low-income white communities (JAMA Intern Med. 2019 Feb 11. doi: 10.1001/jamainternmed.2018.6721).

“Whereas most epidemics predominate within social minority groups and previous US drug epidemics have typically been concentrated in nonwhite communities, the current opioid crisis is largely found among lower-income and majority-white communities,” Joseph Friedman, MPH, from the University of California, Los Angeles, and his colleagues wrote in their study. “Our analysis suggests that, at least in California, an important determinant of this phenomenon may be that white individuals have a higher level of exposure than nonwhite individuals to opioid prescriptions on a per capita basis through the health care system.”

Mr. Friedman and his colleagues analyzed 29.7 million prescription drug records from California’s Controlled Substance Utilization Review and Evaluation System in and examined the prevalence of opioids, benzodiazepines, and stimulants by race, ethnicity, and income level in 1,760 zip codes during 2011-2015. The researchers estimated the prevalence of opioid prescriptions in each zip code by calculating the number of people per zip code receiving an opioid prescription divided by the population of the zip code during each year.

Overall, 23.6% of California residents received at least one opioid prescription each year of the study. The researchers found 44.2% of individuals in zip codes with the lowest income but highest proportion of white residents and 16.1% of individuals in areas with the highest income and lowest proportion of white residents had received a minimum of one opioid prescription each year. The prevalence of stimulant prescriptions was 3.8% in zip codes with high income, and a high proportion of white population, compared with a prevalence of 0.6% in areas with low income and a low proportion of white residents. The researchers noted there was no association between income and benzodiazepine prescription, but the prevalence of benzodiazepine prescriptions was 15.7% in zip codes with the highest proportion of white residents, compared with 7.0% in zip codes with a low proportion of white residents.

During the same time period, there were 9,534 opioid overdose deaths in California from causes such as fentanyl, synthetic opioids, and prescription opioids. “Overdose deaths were highly concentrated in lower-income and mostly white areas,” Mr. Friedman and his colleagues wrote. “We observed an approximate 10-fold difference in overdose rates across the race/ethnicity–income gradient in California.”

Although the number of opioids prescribed each year has decreased since 2012, in a research letter published in the same issue noted that the rate of prescribing is still higher than it was in 1999 (JAMA Intern Med. 2019 Feb 11. doi: 10.1001/jamainternmed.2018.6989). The authors also pointed out increases in the duration of opioid prescriptions and wide regional variations in opioid prescribing rates.

In their study, Gery P. Guy Jr., PhD, and his colleagues used data from the IQVIA Xponent database from approximately 50,400 retail pharmacies and discovered the average morphine milligram equivalent (MME) per capita had decreased from 641.4 MME per capita in 2015 to 512.6 MME per capita in 2017 (20.1%). The number of opioid prescriptions also decreased from 6.7 per 100 persons in 2015 to 5.0 per 100 persons in 2017 (25.3%). However, during 2015-2017, the average duration of opioid prescriptions increased from 17.7 days to 18.3 days (3.4%), while the median duration increased during the same time from 15.0 days to 20.0 days (33.3%).

While 74.7% of counties reduced the number of opioids prescribed during 2015-2017 and there also were reductions in the rate of high-dose prescribing (76.6%) and overall prescribing rates (74.7%), Dr. Guy of the Centers for Disease Control and Prevention and his colleagues found “substantial variation” in 2017 prescription rates at the county level, with opioids prescribed at 1,061.0 MME per capita at the highest quartile, compared with 182.8 MME per capita at the lowest quartile.

“Recent reductions could be related to policies and strategies aimed at reducing inappropriate prescribing, increased awareness of the risks associated with opioids, and release of the CDC Guideline for Prescribing Opioids for Chronic Pain–United States, 2016,” Dr. Guy and his colleagues noted.

In an additional article published in the same JAMA Internal Medicine issue, Bennett Allen, a research associate at the New York City Department of Health and Mental Hygiene and his colleagues examined the rate of opioid overdose deaths for non-Hispanic white, non-Hispanic black, Hispanic, and undefined other races in New York (JAMA Intern Med. 2019 Feb 11. doi: 10.1001/jamainternmed.2018.7700). They identified 1,487 deaths in 2017, which included 556 white (37.0%), 421 black (28.0%), 455 Hispanic (31.0%), and 55 undefined (4.0%) opioid overdose deaths. There was a higher rate of fentanyl and/or heroin overdose deaths from younger (aged 15-34 years) white New Yorkers (22.2/100,000 persons; 95% confidence interval, 19.0-25.5), compared with younger black New Yorkers (5.8/100,000; 95% CI, 4.0-8.2) and Hispanic (9.7/100,000; 95% CI, 7.6-12.1).

Among older residents (aged 55-84 years), Mr. Allen and his colleagues found higher rates of fentanyl and/or heroin overdose for black New Yorkers (25.4/100,000 persons; 95% CI, 20.9-30.0), compared with older white New Yorkers (9.4/100,000 persons; 95% CI, 7.3-11.8), as well as significantly higher rates of cocaine overdose (25.4/100,000 persons; 95% CI, 20.9-30.0), compared with white (5.1/100,000 persons; 95% CI, 3.6-7.0) and Hispanic residents (11.8/100,000 persons; 95% CI, 8.9-15.4).

“The distinct age distribution and drug involvement of overdose deaths among New York City blacks, Latinos, and whites, along with complementary evidence about drug use trajectories, highlight the need for heterogeneous approaches to treatment and the equitable allocation of treatment and health care resources to reach diverse populations at risk of overdose,” Mr. Allen and his colleagues wrote.

Dr. Schriger reported support from Korein Foundation for his time working on the study by Friedman et al. The other authors reported no conflicts of interest.

SAN FRANCISCO – When used as first-line therapy for renal cell carcinoma (RCC), the combination of pembrolizumab and axitinib has similar safety and better efficacy than single-agent sunitinib, the current standard of care, according to findings of the KEYNOTE-426 trial that will be reported at the 2019 Genitourinary Cancers Symposium sponsored by the American Society for Clinical Oncology, the American Society for Radiation Oncology, and the Society of Urologic Oncology.

“Axitinib is usually licensed and usually used in sunitinib-refractory disease. However, there is data for both pembrolizumab and axitinib in the frontline setting,” said lead author Thomas Powles, MBBS, MRCP, MD, of Barts Health and the Royal Free NHS Trusts, Barts Cancer Institute, and Queen Mary University of London. A phase 1b trial testing the combination showed an impressive 73% objective response rate and acceptable toxicity (Lancet Oncol. 2018;19:405-15), prompting further investigation.

The 861 patients in KEYNOTE-426, a phase 3, randomized, controlled trial, were evenly assigned to combination therapy with the immune checkpoint inhibitor pembrolizumab (Keytruda), which targets programmed death–1, plus the tyrosine kinase inhibitor axitinib (Inlyta), which targets vascular endothelial growth factor and platelet-derived growth factor, or to monotherapy with the tyrosine kinase inhibitor sunitinib (Sutent), which also targets those growth factors.

Main results reported in a presscast held before the symposium showed that, with a median follow-up of 12.8 months, pembrolizumab-axitinib reduced the risk of progression-free survival events by a relative 31% and the risk of death by a relative 47%, compared with sunitinib. The combination had a rate of grade 3-5 treatment-related adverse events similar to the rate with sunitinib alone.

“The benefit of pembrolizumab plus axitinib was seen irrespective of IMDC [International Metastatic Renal Cell Carcinoma Database Consortium] risk group or PD-L1 [programmed death–ligand 1] status,” Dr. Powles noted. “Pembrolizumab and axitinib should be a standard of care in this setting, in my opinion.”

“This is a very significant trial, and it’s going to impact on patient management going forward, as it works through the regulatory process,” commented ASCO Expert and presscast moderator Robert Dreicer, MD, MS, MACP, FASCO, who is also deputy director and associate director of clinical research at the University of Virginia Cancer Center and a professor of medicine and urology at the University of Virginia, Charlottesville.

Study details

Patients in KEYNOTE-426 had newly diagnosed or recurrent stage IV clear cell RCC and had not received any previous systemic treatment for their advanced disease. They were randomized to pembrolizumab (200 mg intravenously every 3 weeks up to 35 cycles) plus axitinib (5 mg orally twice daily), or to sunitinib (50 mg orally once daily for first 4 weeks of each 6-week cycle).

Median overall survival was not reached in either group, but the 12-month rate was 89.9% with pembrolizumab-axitinib versus 78.3% with sunitinib, Dr. Powles reported in the presscast. The difference corresponded to a near halving of the risk of death with the combination (hazard ratio, 0.53; P less than .0001).

Median progression-free survival was 15.1 months with pembrolizumab-axitinib and 11.1 months with sunitinib. The difference corresponded to a nearly one-third reduction in the risk of events with the combination (HR, 0.69; P = .0001). “The 11.1 months is quite long for a control arm, so there’s nothing from these data to suggest that sunitinib underperformed in this trial,” he noted.

Pembrolizumab-axitinib was also associated with a higher objective response rate (59.3% vs. 35.7%; P less than .0001). The median duration of response was not reached with the former, compared with 15.2 months with the latter.

“Pembrolizumab and axitinib had a manageable safety profile,” Dr. Powles said. The rate of grade 3-5 treatment-related adverse events was 62.9% with the combination and 58.1% with sunitinib monotherapy.

The rate of events leading to death was similar at 0.9% and 1.6%, respectively. The rate of events leading to discontinuation of any treatment was 25.9% for pembrolizumab-axitinib and 10.1% for sunitinib, and the rate of events leading to discontinuation of both drugs in the combination was 8.2%.

Dr. Powles reported that he has a consulting or advisory role with Genentech/Roche, Bristol-Myers Squibb, Merck, Novartis, and AstraZeneca; has a nonspecified relationship with Ipsen and Bristol-Myers Squibb; receives honoraria from Roche/Genentech, Bristol-Myers Squibb, and Merck; and receives research funding from Astra-Zeneca/MedImmune and Roche/Genentech. The study was funded by Merck.

“The benefit of pembrolizumab plus axitinib was seen irrespective of IMDC [International Metastatic Renal Cell Carcinoma Database Consortium] risk group or PD-L1 [programmed death–ligand 1] status,” Dr. Powles noted. “Pembrolizumab and axitinib should be a standard of care in this setting, in my opinion.”

“This is a very significant trial, and it’s going to impact on patient management going forward, as it works through the regulatory process,” commented ASCO Expert and presscast moderator Robert Dreicer, MD, MS, MACP, FASCO, who is also deputy director and associate director of clinical research at the University of Virginia Cancer Center and a professor of medicine and urology at the University of Virginia, Charlottesville.

Study details

Patients in KEYNOTE-426 had newly diagnosed or recurrent stage IV clear cell RCC and had not received any previous systemic treatment for their advanced disease. They were randomized to pembrolizumab (200 mg intravenously every 3 weeks up to 35 cycles) plus axitinib (5 mg orally twice daily), or to sunitinib (50 mg orally once daily for first 4 weeks of each 6-week cycle).

Median overall survival was not reached in either group, but the 12-month rate was 89.9% with pembrolizumab-axitinib versus 78.3% with sunitinib, Dr. Powles reported in the presscast. The difference corresponded to a near halving of the risk of death with the combination (hazard ratio, 0.53; P less than .0001).

Median progression-free survival was 15.1 months with pembrolizumab-axitinib and 11.1 months with sunitinib. The difference corresponded to a nearly one-third reduction in the risk of events with the combination (HR, 0.69; P = .0001). “The 11.1 months is quite long for a control arm, so there’s nothing from these data to suggest that sunitinib underperformed in this trial,” he noted.

Pembrolizumab-axitinib was also associated with a higher objective response rate (59.3% vs. 35.7%; P less than .0001). The median duration of response was not reached with the former, compared with 15.2 months with the latter.

“Pembrolizumab and axitinib had a manageable safety profile,” Dr. Powles said. The rate of grade 3-5 treatment-related adverse events was 62.9% with the combination and 58.1% with sunitinib monotherapy.

The rate of events leading to death was similar at 0.9% and 1.6%, respectively. The rate of events leading to discontinuation of any treatment was 25.9% for pembrolizumab-axitinib and 10.1% for sunitinib, and the rate of events leading to discontinuation of both drugs in the combination was 8.2%.

Dr. Powles reported that he has a consulting or advisory role with Genentech/Roche, Bristol-Myers Squibb, Merck, Novartis, and AstraZeneca; has a nonspecified relationship with Ipsen and Bristol-Myers Squibb; receives honoraria from Roche/Genentech, Bristol-Myers Squibb, and Merck; and receives research funding from Astra-Zeneca/MedImmune and Roche/Genentech. The study was funded by Merck.

LAS VEGAS – Inflammatory bowel disease (IBD) can disrupt both fertility and pregnancy, especially if it’s not fully controlled, and there’s a risk that the condition can be passed onto an unborn child. Still a new study suggests many patients with IBD don’t receive appropriate reproductive counseling.

Nearly two-thirds of 100 patients surveyed at a single center reported that no physician had talked to them about reproductive topics, and some said they’d considered not having children because of the condition. “Really fundamental subjects have not made their way into the interactions between patients and their care teams,” coauthor and gastroenterologist Sarah Streett, MD, AGAF, of Stanford (Calif.) University, said in an interview before the study was presented at the annual congress of the Crohn’s & Colitis Foundation and the American Gastroenterological Association.

IBD can lower fertility in both sexes and boost complications in pregnancy. “The good news is that almost all the medications used for IBD appear safe,” Dr. Streett said. “In fact, the safety risks for the baby and the pregnancy revolve around not having IBD under good control.”

Unfortunately, she said, misinformation is common. “Patients who become pregnant or are trying to become pregnant, and are worried about potential harm to the baby, will stop the medications due to incorrect information. Or they’ll be told by their health care team to stop their medications.”

Dr. Streett and study lead author Aarti Rao, MD, a gastroenterology fellow at Stanford, launched their study of IBD clinic patients to gain more understanding about patient knowledge. “We know from research already published that those with IBD have a lot of concerns about starting families and don’t have a lot of information to base their decision making on,” Dr. Streett said. “We wanted to evaluate that in our population and see how much people knew and what the need was.”

In 2018 and 2019, Dr. Streett and Dr. Rao gave an anonymous, validated 17-question survey to patients aged 18-45 with IBD. One hundred patients responded (median age = 30, 54% female, 59% white, 66% with incomes over $100,000, 52% with ulcerative colitis, 21% with prior IBD surgery, 71% with prior IBD hospitalization).

Just over a third – 35% – of the patients said they’d been counseled about reproductive health by a physician. This finding reflects findings in previous research, said Dr. Rao, who spoke in an interview.

Just 15% of those who’d undergone IBD surgery reported getting guidance about the effects of surgery on fertility.

More than a third (35%) of women and 15% of men said they’d considered not having children because of their IBD. In fact, “most potential dads and moms have the chance to do very well,” Dr. Streett said.

Without reproductive counseling, she added, parents won’t know about the risks of passing on IBD. According to Dr. Rao, there’s an estimated less than 5% chance that IBD will be passed on to children if one parent has the condition; the risk is much higher if both parents have it.

Going forward, “there’s a really urgent need for proactive counseling on the part of gastroenterologists and health care teams to give people of childbearing age the right information so they can be informed to make the best decisions,” Dr. Streett said.

The study was funded by a philanthropic grant. The study authors report no relevant disclosures.

The mother of three looked tired and little worried. She wasn’t one to bring her kids to the pediatrician’s office with every minor illness, but her youngest had 3 days of fever, runny nose, cough, and little of her normal energy.

DavidWhalen/Thinkstock

The pediatrician entered the room and smiled sympathetically.

“We ran tests for flu and RSV [respiratory syncytial virus] and it’s neither of those so. ...”

“So it’s just a virus that we don’t routinely test for and it’s going to need to run its course,” the mother finished his sentence. She knew the drill.

Before the doctor could leave the room though, the mother had one more question. “You don’t think it could be adenovirus do you?”

Most years, influenza and RSV command center stage, and adenovirus is relegated to the wings. It is not so much lack of disease or morbidity, but rather lack of recognition. Yes, we all learned in medical school that it is a cause of epidemic keratoconjunctivitis, but many adenoviral infections are clinically indistinguishable from infections caused by other viruses. Common symptoms – fever, cough, sore throat, and malaise – overlap with those caused by influenza. Like rhinovirus, adenovirus can cause common cold symptoms. Like RSV, it can cause bronchiolitis. Just like parainfluenza, it can cause croup. It can cause a pertussislike syndrome with prolonged cough, and enteric adenoviruses, especially types 40 and 41, cause gastroenteritis that mimics norovirus or rotavirus infection.

Testing for adenovirus is not readily available or routine in most pediatricians’ offices, and while many hospitals and reference labs offer adenovirus polymerase chain reaction testing as part of a comprehensive respiratory virus panel, the test can be expensive and unlikely to change management in most ambulatory patients. This makes it difficult to count the number of adenoviruses annually.

This winter though, adenovirus was in the news ... repeatedly. In November 2018, CBS News reported that a University of Maryland freshman had died of an adenovirus-related illness. The family of Olivia Paregol told reporters that she was being treated for Crohn’s disease. Immune suppression is one recognized risk factor for more severe adenoviral disease; underlying heart and lung disease are others. Testing at the Centers for Disease Control and Prevention revealed that the student and several others on campus were infected with adenovirus type 7, a strain that has been associated with outbreaks of acute, severe respiratory illness in military recruits. As of Jan. 24, 2019, university officials reported 42 confirmed cases of adenovirus in University of Maryland students, 13 of which were confirmed as adenovirus 7.

Adenovirus type 7 also caused an outbreak at a pediatric long-term care facility in New Jersey late last year. Between Sept. 26 and Nov. 11, 2018, 36 residents and 1 staff member became ill. Eleven individuals died. In an unrelated outbreak at a second pediatric long-term care facility, 17 residents were affected between Oct. 20 and Dec. 10, 2018. Adenovirus 3 was identified and all children recovered.

Depending on your perspective, measures to prevent the spread of adenovirus are elegantly simple, evidence-based, public health intervention or maddeningly little more than common sense. Wash your hands often with soap and water. Avoid touching your eyes, mouth, and nose with unwashed hands. Avoid close contact with people who are sick. The latter is easier if those who are sick stay home. Prior to the start of the most recent academic semester at the University of Maryland, university officials urged students who were sick not to return to campus but to stay at home to rest and recover. Those who fell ill on campus were urged to return home via nonpublic transportation if possible. Those who stayed on campus were advised to stay in their living spaces and clean high-touch surfaces with bleach. Like other nonenveloped viruses, adenovirus is not easily destroyed by many commonly used disinfectants. Under ideal conditions, it can survive on surfaces – remaining infectious – for up to 3 months.

Back at the pediatrician’s office, “We need an adenovirus vaccine,” the mother said as she picked up her child and headed for the door.

There is, in fact, a live oral vaccine that protects against adenovirus types 4 and 7. It is only approved for use in United States military personnel aged 17-50 years and it is given to all recruits as soon as they enter basic training. It works too. Before vaccine was available, up to 80% of recruits became infected during their initial training, half of those developing significant illness and a quarter being hospitalized. When the current vaccine was introduced in 2011, there was a 100-fold decrease in adenovirus-related disease burden (from 5.8 to 0.02 cases per 1,000 person-weeks, P less than .0001). That translates to 1 death, 1,100-2,700 hospitalizations and 13,000 febrile illnesses prevented each year (Clin Infect Dis. 2014 Oct 1. doi: 10.1093/cid/ciu507).

Some experts have suggested that adenovirus vaccine could be useful in civilian populations, too, but I question what the public reception would be. We have safe influenza vaccines that reduce the need for hospitalization and reduce mortality from influenza, but we still can’t convince some people to immunize themselves and their children. In the last 4 years, flu vaccination rates among children have remained just shy of 60% and adult rates are even lower. Collectively, we don’t seem to be ready to relinquish – or at least diminish – the annual suffering that goes with flu. I have to wonder if the same would be true for adenovirus.

Are residents generally prepared for fellowship interviews? Applications to the Fellowship Match through the National Residency Matching Program (NRMP) Specialties Matching Service (SMS) are at an all-time high, but there is limited data regarding the preparedness of residents who go through the fellowship interview process, said Kelvin Wong, MD, a coauthor of research describing a new approach to fellowship interview preparation, which may be generalizable to hospitalists in applying for other positions.

“Applicants receive little to no feedback after their interviews and are thus likely to repeat the same mistakes throughout the process. Verbal feedback from our own fellowship directors indicated that residents as a whole are unprepared to interview,” according to an abstract written by Dr. Wong and his colleagues.

Dr. Wong wanted to investigate the effects of a standardized fellowship interview preparation course on resident preparedness. He and his coauthors developed a formal preparation course for the applicants in the summer of 2017.

Precourse surveys showed that only 17.65% of residents felt prepared to go on interviews; postcourse surveys showed a rise in this number to 82.35%. Immediately after their mock interview, only 27.78% of residents rated their overall interview skills as “very good” or “excellent,” whereas 87.5% of interviewers and 70.59% of observers rated their skills to be “very good” or “excellent.”

A final survey will be given to the applicants and the fellowship program directors once the applicants have completed all of their actual interviews.

“This demonstrates the potential positive impact that mock interviews and standardized interview preparation courses can have, which may be generalizable to hospitalists applying for other positions,” Dr. Wong said. “Specifically for teaching hospitalists in teaching hospitals, the institution of such fellowship interview preparation courses may improve resident preparedness for the fellowship application process.”

Immediately after their mock interview, only 27.78% of residents rated their overall interview skills as “very good” or “excellent,” whereas 87.5% of interviewers and 70.59% of observers rated their skills to be “very good” or “excellent.”

A final survey will be given to the applicants and the fellowship program directors once the applicants have completed all of their actual interviews.

“This demonstrates the potential positive impact that mock interviews and standardized interview preparation courses can have, which may be generalizable to hospitalists applying for other positions,” Dr. Wong said. “Specifically for teaching hospitalists in teaching hospitals, the institution of such fellowship interview preparation courses may improve resident preparedness for the fellowship application process.”

Are residents generally prepared for fellowship interviews? Applications to the Fellowship Match through the National Residency Matching Program (NRMP) Specialties Matching Service (SMS) are at an all-time high, but there is limited data regarding the preparedness of residents who go through the fellowship interview process, said Kelvin Wong, MD, a coauthor of research describing a new approach to fellowship interview preparation, which may be generalizable to hospitalists in applying for other positions.

“Applicants receive little to no feedback after their interviews and are thus likely to repeat the same mistakes throughout the process. Verbal feedback from our own fellowship directors indicated that residents as a whole are unprepared to interview,” according to an abstract written by Dr. Wong and his colleagues.

SAN FRANCISCO – Men with metastatic castrate-resistant prostate cancer (mCRPC) who have exhausted conventional treatment options have very good outcomes when treated with the novel targeted radioligand lutetium-177 PSMA-617 (LuPSMA), finds a single-center phase 2 trial to be reported at the 2019 Genitourinary Cancers Symposium sponsored by the American Society of Clinical Oncology, ASTRO, and the Society of Urologic Oncology.

“Whilst there have been major advances in the last few years with several drugs that prolong survival in these men, the disease remains fatal in a relatively short period of time, and there is an urgent need for new effective therapies,” said lead study author Michael Hofman, MBBS, professor of nuclear medicine at the Peter MacCallum Cancer Centre, Melbourne.

LuPSMA is a radiolabeled small molecule that binds with high affinity to PSMA (prostate-specific membrane antigen), enabling targeted delivery of beta radiation to lesions throughout the body. To be eligible for the trial, patients had to have PSMA-positive disease. Results among the first 30 patients treated showed good activity and acceptable toxicity (Lancet Oncol. 2018;19:825-33), leading to enrollment of an expansion cohort of 20 patients.

With a median follow-up of 23.5 months among all 50 patients, nearly two-thirds achieved a 50% or greater reduction in their PSA level, Dr. Hofman reported in a presscast held before the symposium. Median overall survival exceeded 12 months for the whole cohort and was especially good for the subset achieving that level of PSA reduction, at 18 months.

“This is a single-arm study with no control arm. So whilst my impression is that this is a life-prolonging therapy, this is not a claim that we can make yet because there is no comparator arm with an existing treatment or therapy,” he acknowledged. However, data from the literature suggest that in the absence of this novel radioligand, the patients would likely have survived only about 6-9 months.

“These results in 50 men provide further confidence to our previously published 30-patient cohort, demonstrating high response rates and low toxicity in men with mCRPC who have progressed after multiple conventional therapies,” Dr. Hofman said. The findings also “support a novel mechanism of action for this therapy compared to existing therapies.”

The favorable data have led to initiation of two randomized controlled trials: the phase 2 TheraP trial (NCT03392428) comparing LuPSMA with cabazitaxel (Jevtana), and the phase 3 VISION trial (NCT03511664), comparing LuPSMA with best standard of care. “We really need the larger trials ... to get a confident assessment on whether it improves survival and by how much,” he maintained. “But my impression, seeing these patients come into the clinic very sick and seeing them improve on the therapy, and knowing those averages [for survival without this therapy], is that these trials are likely to be positive.”

“As a clinician, I will tell you that this is a very intriguing agent, and the VISION study, which is a registration trial, is open in the U.S.,” said ASCO expert and presscast moderator Robert Dreicer, MD, MS, MACP, FASCO, deputy director and associate director of clinical research at the University of Virginia Cancer Center and professor of medicine and urology at the University of Virginia, Charlottesville.
 

Study details

Of the 76 patients screened for the LuPSMA trial, 16 (21%) were ineligible because of insufficient PSMA uptake on a PSMA–FDG PET scan. “The majority of patients with this disease are suitable. Probably somewhere in the range of 20% to 30%, depending on how you measure it, may not be suitable,” Dr. Hofman said.

The 50 patients ultimately enrolled had aggressive disease, as indicated by a median PSA doubling time of 2.6 months. Most had previously received abiraterone (Zytiga), enzalutamide (Xtandi), or both (90%), as well as docetaxel (84%) or cabazitaxel (48%). “Many of these men had no further treatment options, and without this study open, they probably would have received end-of-life palliative care,” he said.

The median number of LuPSMA cycles administered was four, according to data reported in the presscast leading up to the symposium. Eight patients received fewer than four cycles because they had an exceptional response, while 10 patients did not complete all planned cycles because of disease progression.

Main results showed that PSA levels fell by at least 30% in 74% of patients, at least 50% in 64% of patients, and at least 80% in 44% of patients. Only two patients did not see any reduction. “We think this is probably a feature of our careful selection of patients with the PET scanning up front to really enrich the study for patients who are likely to benefit from the treatment,” Dr. Hofman said. The reductions in PSA were accompanied by reductions in positive lesions on PSMA–FDG PET.

For the entire cohort, median overall survival was 13.3 months. But it was significantly longer for those with versus without at least a 50% PSA decline (18.0 vs. 8.7 months; P = .001).

Fourteen patients who experienced progression on LuPSMA were given additional doses after the trial ended, as part of an off-trial expanded-access program. Fully 64% of these patients achieved a PSA reduction of at least 50%, and median overall survival in all of the retreated patients was 33 months.

Dr. Hofman disclosed that he has a consulting or advisory role with Endocyte; receives research funding (institutional) from Endocyte; and receives travel, accommodations, and/or expenses from Ipsen and Sanofi. The trial received research funding from the Peter MacCallum Cancer Centre.

Previous dengue exposure may confer a protective effect against Zika virus infection, according to a paper published in Science.

In a prospective cohort study, researchers followed 1,453 urban residents in Salvador, Brazil, to assess the impact of the 2015 Zika virus outbreak in the region. Data on dengue immunity was available for 642 of these individuals.

Overall, 73% of the cohort were seropositive for Zika virus. However, the frequency of seropositivity varied significantly by location, from 29% in a valley in the northeastern sector of the study area to 83% in the southeast corner; the authors wrote that this was consistent with some form of acquired immunity “blunting the efficiency of transmission.”

When researchers looked at the relationship between prior immunity to the dengue virus and the risk of Zika infection, they found that each doubling of total IgG titers against dengue NS1 was associated with a 9% reduction in the risk of Zika virus infection.

Individuals in the highest tertile of dengue IgG titers showed a 44% reduction in the odds of Zika seropositivity, compared with individuals with no or low dengue IgG titers, while those in the middle tertile of dengue IgG titer had a 38% reduction.

“These findings provide empirical support for the hypothesis that accumulated immunity drove ZIKV [Zika virus] to local extinction by reducing the efficiency of transmission,” wrote Isabel Rodriguez-Barraquer, MD, PhD, from the department of medicine at the University of California, San Francisco, and her coauthors.

Individuals who were infected with the Zika virus but had high dengue IgG titers were significantly less likely to exhibit fever with viral infection, but had the same risk of developing rash as those with low or no IgG titers.

Researchers also examined the link between a subclass of IgG antibodies that are associated with more recent exposure to dengue virus – within the prior 6 months – and the risk of Zika virus infection. In contrast, they found that the levels of this subclass of antibodies, known as IgG3, were positively associated with an increased risk of Zika virus infection. Each doubling in IgG3 levels was associated with a 23% increase in the odds of being positive for Zika.

“This positive association might reflect an immune profile, in individuals who have experienced a recent DENV [dengue virus] infection, that is associated with having a greater risk of a subsequent ZIKV infection,” the authors wrote. “Alternatively, it is also possible that higher levels of IgG3 are a proxy for frequent DENV exposure and thus greater risk of infection by Aedes aegypti–transmitted viruses.”

The study was supported by Yale University, a number of Brazilian research organizations, the Research Support Foundation for the State of São Paulo, CuraZika Foundation, Wellcome Trust, and the National Institutes of Health. Three authors are listed on a patent application related to the work, and one reported an honoraria from Sanofi-Pasteur.

Eight weeks of a mindfulness intervention known as acceptance and commitment therapy (ACT) significantly improved stress and depression among patients with inflammatory bowel disease, and these improvements persisted for at least 12 weeks after therapy ended, according to the results of a randomized, controlled trial.

Source: The American Gastroenterological Association

In the intention-to-treat analysis, stress symptoms, as measured by the Depression Anxiety and Stress Scales (DASS-21), improved by 39% at week 8 and by 45% at week 20, reported Brona Wynne, PhD, of University College Dublin together with her associates. These improvements were highly significant compared with baseline and treatment as usual (P = .001 for both comparisons). “Post hoc analyses indicated that baseline stress levels were similar in control and treatment groups,” the researchers wrote in Gastroenterology. “The results of the per protocol analysis were comparable, with a 43% and 49% reduction in stress in the treatment group from baseline to 8 and 20 weeks.”

Multiple studies have documented high levels of stress and psychological dysfunction among patients with Crohn’s disease and ulcerative colitis. Studies of various mindfulness therapy, relaxation, stress management, cognitive-behavioral therapy, and hypnotherapy interventions often failed to collect key clinical data or were underpowered, uncontrolled, and unrandomized. Acceptance and commitment therapy uses mindfulness to identify adverse thoughts and experiences, accept these as part of life, and recommit to “move towards values that have been identified and adopted by the individual,” the investigators wrote. “This can be defined as the ability to contact the present moment more fully as a conscious human being and to change, or persist in, behavior when doing so serves valued ends.”

Their single-center study, which they said was the first to evaluate ACT in IBD patients, included 79 individuals with stable or mildly active Crohn’s disease (38 patients) or ulcerative colitis (41 patients) who were randomly assigned to ACT (37 patients) or control treatment as usual (42 patients). The two comparison groups were demographically and clinically similar. The ACT program involved eight 90-minute, weekly sessions of groups of 14-16 individuals, led by a single psychologist who tailored the course material toward IBD with a focus on lowering stress. An independent psychologist observed each session to assess adherence to protocol.

Not only did ACT meet the primary study endpoint, it also produced a 25% decrease in perceived stress (on a 1-10 scale) by week 8 and a 27% decrease in perceived stress by week 20 (P less than .001 versus treatment as usual). Depression scores in the ACT group also fell by 47% by week 8 and by 45% at week 20 (P = .01 versus treatment as usual). Anxiety levels decreased by 29% at week 8 and by 31% at week 20, but these improvements did not significantly differ from those in the control group (P = .39).

Interestingly, ACT did not significantly improve symptom burden, activities of daily living, disease-related worry, general well-being, C-reactive protein (CRP) levels, fecal calprotectin levels, or scores on the version used of the Clinical Assessment of Depression (CAD) or the short Mayo assessment. Hair cortisol levels showed an association with baseline stress and anxiety, but not with treatment response.

Care programs for IBD increasingly emphasize mental health services despite a lack of robust trials to support these interventions, the investigators noted. Thus, their findings highlight “the need for researchers and clinicians to further develop and optimize the content and delivery of psychological programs for IBD patients.”

Tillotts Pharma and Boston Scientific provided partial funding, but had no other role in the study. The researchers reported having no relevant conflicts of interest.

Their single-center study, which they said was the first to evaluate ACT in IBD patients, included 79 individuals with stable or mildly active Crohn’s disease (38 patients) or ulcerative colitis (41 patients) who were randomly assigned to ACT (37 patients) or control treatment as usual (42 patients). The two comparison groups were demographically and clinically similar. The ACT program involved eight 90-minute, weekly sessions of groups of 14-16 individuals, led by a single psychologist who tailored the course material toward IBD with a focus on lowering stress. An independent psychologist observed each session to assess adherence to protocol.

Not only did ACT meet the primary study endpoint, it also produced a 25% decrease in perceived stress (on a 1-10 scale) by week 8 and a 27% decrease in perceived stress by week 20 (P less than .001 versus treatment as usual). Depression scores in the ACT group also fell by 47% by week 8 and by 45% at week 20 (P = .01 versus treatment as usual). Anxiety levels decreased by 29% at week 8 and by 31% at week 20, but these improvements did not significantly differ from those in the control group (P = .39).

Interestingly, ACT did not significantly improve symptom burden, activities of daily living, disease-related worry, general well-being, C-reactive protein (CRP) levels, fecal calprotectin levels, or scores on the version used of the Clinical Assessment of Depression (CAD) or the short Mayo assessment. Hair cortisol levels showed an association with baseline stress and anxiety, but not with treatment response.

Care programs for IBD increasingly emphasize mental health services despite a lack of robust trials to support these interventions, the investigators noted. Thus, their findings highlight “the need for researchers and clinicians to further develop and optimize the content and delivery of psychological programs for IBD patients.”

Tillotts Pharma and Boston Scientific provided partial funding, but had no other role in the study. The researchers reported having no relevant conflicts of interest.

In the intention-to-treat analysis, stress symptoms, as measured by the Depression Anxiety and Stress Scales (DASS-21), improved by 39% at week 8 and by 45% at week 20, reported Brona Wynne, PhD, of University College Dublin together with her associates. These improvements were highly significant compared with baseline and treatment as usual (P = .001 for both comparisons). “Post hoc analyses indicated that baseline stress levels were similar in control and treatment groups,” the researchers wrote in Gastroenterology. “The results of the per protocol analysis were comparable, with a 43% and 49% reduction in stress in the treatment group from baseline to 8 and 20 weeks.”

Diabetes mellitus (DM) was the third most common medical diagnosis in 2016.¹ Uncontrolled DM can lead to cardiovascular disease, nephropathy, neuropathy, and retinopathy. It is estimated that only 52.5% of patients with DM have achieved their goal hemoglobin A_1c (HbA_1c) level. The 2018 American Diabetes Association (ADA) clinical guidelines lack strong recommendations on sequential therapy for patients who have received a diagnosis of type 2 diabetes mellitus (T2DM) and have been unable to achieve their goal HbA_1c level with lifestyle changes and maximum-dose metformin.² Although those guidelines support treatment intensification with a glucagon-like peptide 1 receptor agonist (GLP-1 RA), prescribing patterns for T2DM most commonly include adding insulin to try to control blood glucose and reduce long-term comorbidities.^2,3

Related: 

Insulin therapy is known for its ability to effectively lower blood glucose and HbA_1c levels but comes with many limitations. Mealtime insulin has the highest risk of hypoglycemia, causes significant weight gain, requires several additional injections per day, and additional monitoring of blood glucose.^4,5 The 2018 ADA guidelines state that hypoglycemia is the major limiting factor in the management of insulin-treated T2DM.²

Compared with mealtime insulin, GLP-1 RAs have the benefit of reducing the risk of hypoglycemia, weight gain, and number of daily injections.⁵ In addition, compared with insulin alone, GLP-1 RAs have the advantage of reducing glycemic variability.⁶ These advantages are especially attractive in the treatment of geriatric patients. Given its mechanism of action, liraglutide is expected to have an effect on both fasting and postprandial blood glucose. There are no recommendations on how to empirically reduce the dose of insulin when starting liraglutide.⁷

Background

GLP-1 is an incretin hormone that is secreted in response to meal ingestion. GLP-1 stimulates insulin release, suppresses elevated glucagon levels, and delays gastric emptying. Patients with a DM diagnosis have impaired secretion of GLP-1.⁸

The GLP-1 RA liraglutide was approved by the FDA in January 2010 as a once-daily injection for patients with uncontrolled T2DM despite lifestyle changes and metformin monotherapy. Because of its intermediate half-life, liraglutide has an effect on both fasting and postprandial blood glucose.⁷ GLP-1 RAs are associated with reduced hypoglycemic episodes—an association attributable to the mechanism of action and potentially to improved pancreatic α-cell function.^3,4 In July 2016, results of the LEADER trial showed that liraglutide therapy had a cardiovascular benefit in high-risk patients.⁸ In October 2017, liraglutide was FDAapproved for reducing 3-point major adverse cardiac events.⁷

Xultophy (Novo Nordisk, Plainsboro, NJ) is a fixed-dose medication combining degludec, a long-acting basal insulin analog, with liraglutide. As seen in the DUAL trials, Xultophy was more beneficial in reducing HbA_1c levels than each component alone, and minimized hypoglycemic events, weight gain, and complexity of insulin treatment intensification.^9-11 Therapy that combines basal insulin and a GLP-1 RA may be more effective than either agent as monotherapy and may have a significant impact on cardiovascular risk because of the synergistic vasodilatory, anti-inflammatory, and antioxidant properties of insulin and GLP-1 RA.⁶ In addition, combination therapy offers many benefits over traditional basal and bolus insulin regimens. These benefits include fewer daily injections, additional weight reduction resulting from the reduced insulin requirement, and fewer episodes of hypoglycemia. Reported gastrointestinal adverse effects have been transient and were not augmented when a GLP-1 RA was used in combination with basal insulin.¹¹

Methods

We performed a retrospective chart analysis to quantify the benefit of using liraglutide as an add-on therapy to basal and bolus insulin regimens in veterans treated at VA Boston Healthcare System (VABHS). The analysis evaluated changes in insulin doses and HbA_1c levels when liraglutide was added to these regimens. Patients identified for the study had electronic medication orders for concurrent therapy with liraglutide, insulin glargine, and insulin aspart filled through outpatient VABHS campus pharmacies for at least 3 months between January 2010 and December 2016. Sixty-nine patients who were on basal-bolus insulin for T2DM and who were prescribed liraglutide for treatment intensification were screened for inclusion and exclusion criteria. Data were analyzed at baseline and 3 months after liraglutide treatment.

Study Protocol

The inclusion criteria were patients aged ≥ 18 years, T2DM diagnosis, and therapy with insulin glargine and insulin aspart for at least 3 months before treatment intensi fication with liraglutide. Exclusion criteria were diagnosis of type 1 DM. To accurately quantify mean change in number of insulin units used, the study included patients only if they had been prescribed insulin glargine and insulin aspart before starting liraglutide. All other insulin regimens were excluded. To detect the true change that occurs when liraglutide is added to basal-bolus insulin, the study also excluded patients if they had been previously prescribed another GLP-1 RA. Patients with contraindications to liraglutide, insulin aspart, or insulin glargine were excluded as well. In addition, patients were excluded from the exposed arm if they were injecting < 1.2 mg of liraglutide once daily or if they had been on liraglutide for < 3 months.

Study Outcomes

All 35 patients who met the inclusion and exclusion criteria were included in this retrospective chart review. The primary outcome was determined by changes in HbA_1c level and number of insulin doses 3 months after treatment with liraglutide. For each patient, a chart review was performed to determine the amount of insulin added or reduced during the study period. Data were collected at baseline and 3 months after initiation of liraglutide.

Statistical Analysis

Statistical analyses were performed with SPSS Version 20.0 (IBM, Armonk, NY). Population characteristics and study outcomes with normal distribution were compared using a paired t test and are reported as means with standard deviations. Nonnormally distributed variables (bolus insulin, HbA_1c level) were compared using the nonparametric Wilcoxon rank sum test and are reported as median values with interquartile ranges. Normality was tested with the Shapiro-Wilk test. The primary outcome evaluated was change in number of insulin units used. Secondary outcomes included change in HbA_1c level and change in body weight. A Bonferroni correction for multiple comparisons was used to prevent type I error. Significance at the Bonferroni-corrected level of .01 (.05/5 = .01) is indicated.

Results

Patients were included if they were previously on insulin glargine and insulin aspart before starting liraglutide for treatment intensification. 

As Table 1 indicates, 100% of patients were male, and mean (SD) age was 65.5 (9.3) years. 

Discussion

After 3 months of treatment with liraglutide, patients experienced a significant decrease in HbA_1c levels. Insulin doses also decreased, but this finding was not statistically significant after correcting for multiple testing. These results are similar with those in larger studies of the effectiveness of liraglutide and the addition of liraglutide to insulin therapy. ^6,8,12,13 Liraglutide has been shown to decrease HbA_1c levels, lower rates of progression of kidney failure, decrease weight, and provide cardiovascular benefit.

In a prospective, randomized controlled trial evaluating the effect of adding liraglutide to insulin therapy, 21 of the 37 patients who had T2DM and required more than 100 total units of basal-bolus insulin daily were initiated on liraglutide, and changes in HbA_1c level, body weight, and glycemic variability were compared. Results showed statistically significant improvement in all 3 outcomes in the group treated with liraglutide.⁶ Our findings, in conjunction with those of the larger studies, suggest that many of these results are generalizable to our local veteran population. Importantly, liraglutide was successfully started in pharmacy clinics—an indication that this treatment need not be initiated by an endocrine specialist.

Limitations

Given the lack of gender and racial diversity in this study population, our findings have limited generalizability to other populations. It is possible that, with a larger sample size, these results regarding reduced basal insulin doses would be significant. It has been hypothesized that patients experience fewer episodes of hypoglycemia when insulin doses are reduced, but we were unable to measure the frequency of these episodes. Other study limitations include inability to assess adherence and inability to account for concurrent regimens and/or for lifestyle changes that may have been made during the study period. Further, the study did not collect data on changes made to current DM medication regimens during the study period, and these changes may have influenced outcomes.

Conclusion

Patients who require treatment intensification for insulin-dependent T2DM may benefit from having liraglutide added to their basal-bolus insulin regimen. Liraglutide may prove to be more favorable than bolus insulin when choosing add-on therapy to basal insulin. Benefits include reductions in insulin doses, HbA_1c levels, number of daily injections, and body weight. Therefore, we suggest that empirically reducing basal insulin by 10% to 25% and bolus insulin by 25% to 50% will avoid relative hypoglycemia. Prescribers must keep in mind patient-specific factors when adjusting insulin doses, if these doses are adjusted at all. Follow-up of 2 to 4 weeks is recommended for review of home monitoring of glucose for further insulin adjustments.

This study has important clinical implications. First, the finding of a reduction in HbA_1c levels supports use of liraglutide therapy for HbA_1c reduction in veterans. Second, the number of veterans who were successfully initiated on liraglutide therapy by nonphysician providers indicates that liraglutide can be effectively and safely started in primary care pharmacy clinics, increasing access to the medication.

Patients who require treatment intensification for insulin-dependent T2DM may benefit from having liraglutide added to their basal-bolus insulin regimen. Liraglutide may prove to be more favorable than bolus insulin when choosing add-on therapy to basal insulin. Benefits include reductions in insulin doses, HbA_1c levels, number of daily injections, and body weight. Therefore, we suggest that empirically reducing basal insulin by 10% to 25% and bolus insulin by 25% to 50% will avoid relative hypoglycemia. Prescribers must keep in mind patient-specific factors when adjusting insulin doses, if these doses are adjusted at all. Follow-up of 2 to 4 weeks is recommended for review of home monitoring of glucose for further insulin adjustments.

This study has important clinical implications. First, the finding of a reduction in HbA_1c levels supports use of liraglutide therapy for HbA_1c reduction in veterans. Second, the number of veterans who were successfully initiated on liraglutide therapy by nonphysician providers indicates that liraglutide can be effectively and safely started in primary care pharmacy clinics, increasing access to the medication.

The products, many of which are marketed as dietary supplements, are being sold in a variety of forms, including tablets, capsules, and oils. These drugs are either unapproved or mislabeled and claim to prevent, treat, or cure Alzheimer’s disease, as well as a number of other serious diseases and health conditions, in violation of the Federal Food, Drug, and Cosmetic Act.

“Alzheimer’s is a challenging disease that, unfortunately, has no cure. Any products making unproven drug claims could mislead consumers to believe that such therapies exist and keep them from accessing therapies that are known to help support the symptoms of the disease, or worse, as some fraudulent treatments can cause serious or even fatal injuries,” FDA Commissioner Scott Gottlieb, MD, said in a press release.

In an additional statement, Dr. Gottlieb detailed several new strategies for improving the safety and accuracy of dietary supplements, including efforts to more rapidly communicate to the public potential safety issues with dietary supplement products and to establish a flexible regulatory framework that promotes innovation and upholds product safety.
