Efforts to curb overdiagnosis of thyroid cancer have made a difference in the United States and South Korea, but these countries still have high rates of excess treatment of indolent lesions, according to a recently published global study.

The proportion of thyroid cancer cases attributable to overdiagnosis globally was higher in women (78%) than in men (68%), with this rate varying substantially across countries, wrote Mengmeng Li, PhD, of the Sun Yat-sen University Cancer Center, Guangzhou, China, and coauthors in an October paper in The Lancet Diabetes & Endocrinology.

Overdiagnosis refers to the diagnosis of lesions that would not cause symptoms and that would not progress, if left alone.

Increased testing for thyroid cancer, fueled in large part by the expansion of imaging technologies and progressively more intense and disorganized scrutiny of the thyroid, led many people to be treated for often indolent lesions, exposing them to potential side effects as well as financial and emotional distress.

Li and coauthors estimate that more than 1.7 million people might have been overdiagnosed between 2013 and 2017 in 63 countries.

“Overdiagnosis clearly emerged in some high-resource countries with private-based health systems in which access to healthcare overrules regulatory controls (eg, in the USA) and in some high-quality public health systems with easy and broad access to thyroid gland diagnostic examinations (eg, in Canada),” Li and coauthors wrote. “Conversely, thyroid cancer is less commonly diagnosed in those countries in which access to diagnosis is guided by strong regulatory rules (eg, in Nordic countries).”

Their study drew from almost 40 years of research, including the latest available data from the World Health Organization’s International Agency for Research on Cancer’s (IARC’s) Global Cancer Observatory. Li and coauthors examined patterns in the time trends of thyroid cancer, mortality data, and trends in diagnosis of thyroid cancer before testing became common in many nations.

This approach is needed in estimating overdiagnosis, where it’s not possible to see what’s happening on a case-by-case level, Salvatore Vaccarella, PhD, a scientist at IARC’s Cancer Surveillance Branch, said in an interview.

Researchers can’t tell whether an individual’s detected early-stage cancers would have remained indolent for years or eventually would have put their life at risk, he said. Instead, the patterns emerge through larger studies of the reported cases of cancer like thyroid tumors and then looking at separate datasets on mortality.

“We can only see that as a big phenomenon when we look at population-based data,” Vaccarella said.
 

Persisting Problem

Recognition of the harms of overdiagnosis has resulted in some reduction of the incidence of thyroid cancer in the United States, Li and coauthors wrote. After adjusting for age, incidence has fallen from 19 per 100,000 women in 2013 to 16 per 100,000 women in 2017. The proportion of thyroid cancer attributed to overdiagnosis has dropped from 76% to 68% in the country.

The paper adds to the evidence suggesting that the rise in screening has not changed mortality rates for thyroid cancer. For example, Li and coauthors reported seeing “a small decrease in thyroid cancer mortality rates over time in some European countries, but this decline (less than 1 per 100,000 women) is marginal compared with the increases in incidence (reaching around 100 per 100,000 women).”

“Moreover, previous data show that the downward mortality trends had begun before the wide use of ultrasonography for early detection and that period and birth cohort effects have been declining, probably due to treatment advances and reduced prevalence of risk factors, such as the reduction in iodine deficiency,” they wrote.

In an interview, Amanda Davis, MD, of AnMed, a nonprofit health system based in Anderson, South Carolina, said the new paper from Li and Vaccarella provides further evidence for a cautious approach to thyroid nodules given concerns about overdiagnosis.

If early detection of cancer via discovery of thyroid nodules actually helped patients, mortality rates would have dropped with expansion of screening and the resulting diagnoses, said Davis, who is an associate program director at AnMed’s family medicine residency program and affiliate professor at the Medical University of South Carolina, Charleston.

In many cases, people learn they have thyroid lesions after being tested for other conditions such as ultrasound done on carotid arteries to check for stroke risk. The most common form of thyroid cancer is the papillary form. Papillary thyroid cancer tends to be slow growing, carries a low risk for distant metastasis, and in many cases poses little risk. Some small (< 1 cm) papillary thyroid cancers can be monitored with active surveillance as opposed to thyroid lobectomy.

“So just finding more nodules incidentally or through screening ultrasound and even finding more papillary cancers via these methods does not make people healthier or decrease mortality,” Davis said.

“So just finding more things and even finding more papillary cancers does not increase our ability to treat people and keep them alive longer,” Davis said.

The 5-year survival rate for thyroid cancer overall is 98.1% and varies from 99.9% for localized disease to 55.3% for distant disease, the US Preventive Services Task Force (USPSTF) said in a 2017 publication in JAMA. The task force that year gave a “D” rating on screening of asymptomatic people for thyroid cancer. That means there’s moderate certainty that screening for thyroid cancer in asymptomatic persons results in harms that outweigh the benefits. The decision to give this “D” rating meant this screening is not recommended. That’s still the panel’s view.

“You can think of it as a “D” for ‘don’t screen for thyroid cancer,’ ” in people who present no symptoms of this illness, John Wong, MD, the vice chair of the USPSTF, said in an interview.

In primary care, the challenge is assessing thyroid nodules detected when people undergo testing for another reason, such as an ultrasound of the carotid artery to check for stroke risk.

Thyroid nodules can be detected by ultrasonography in up to 68% of the general population, reported a study in American Family Physician. Nodules with suspicious features or ≥ 1 cm require fine needle aspiration. The Bethesda System for Reporting Thyroid Cytopathology can be used to classify samples, with molecular testing applied to guide treatment when fine needle aspiration yields an indeterminate result.
 

New Thinking on Thyroid Cancer

There’s been a shift in recent years in the approach to how physicians should proceed if certain kinds of thyroid cancer are detected, Cari M. Kitahara, PhD, of the National Cancer Institute noted in a comment accompanying the Li paper.

“Clinicians need to be judicious in the use of thyroid ultrasonography, the diagnostic follow-up of incidentally detected thyroid nodules, and determining the optimal course of treatment,” Kitahara wrote. “For low-risk and incidentally detected tumors, strong consideration should be given to less intensive treatment options (eg, lobectomy, delayed treatment, and active surveillance).”

The American Thyroid Association guidelines encourage de-escalation of treatment for low-risk papillary thyroid carcinoma up to 4 cm.

Physicians often need to make clear to patients how a diagnosis of low-risk papillary thyroid cancer differs from other oncology diagnoses, R. Michael Tuttle, MD, of Memorial Sloan Kettering Cancer Center, New York City, said in an interview.

“I’ll frequently say that everything you’ve ever learned about cancer, you need to forget,” Tuttle said.

Some patients will mistakenly think any cancer diagnosis is a likely death sentence, meaning they should rush to get aggressive treatment. Tuttle has been a leader for many years in efforts in advancing active surveillance as an option for certain people with low-risk thyroid cancer.

“I often start my consultation by saying: ‘We’re going to choose between two right answers here. One right answer is watching right. One right answer is going to surgery,’ ” Tuttle said.

Patients with low-risk thyroid cancer tend to fall into two camps, with maximalists likely to seek quick treatment and minimalists more inclined for surveillance if that’s an option for them, Tuttle said. As opinions have shifted within the medical community about approaches to low-risk thyroid cancer, there’s also been some growing awareness among the public about thyroid overdiagnosis.

“Ten or 15 years ago, people thought we were crazy” to consider active surveillance as an option for low-risk thyroid cancers,” Tuttle said. “Now we have swung, at least in some of the public opinion, to this recognition that every little speck of cancer doesn’t need to be immediately taken out of your body.”

Some patients express regret about having learned that they have low-risk thyroid cancer, Tuttle said.

“Over the last 5 years, it’s not uncommon for patients to ask me, ‘Is this one of those that needs to be treated now, or is this one of those that we wish we would have never found?’ Or people will say, ‘My doctor talked me into an ultrasound, I didn’t want it’ or ‘I had a car wreck, and I found this nodule and I wished I had never found it.’ ”

This study from Li and coauthors was funded by the National Natural Science Foundation of China, the Guangdong Basic and Applied Basic Research Foundation, the Young Talents Program of Sun Yat-sen University Cancer Center, the Italian Association for Cancer Research, and the Italian Ministry of Health. Davis and Tuttle had no relevant financial disclosures.

Adults aged 45-49 years are as likely as are those aged 50 years to complete a fecal immunochemical test (FIT) as an initial screen for colorectal cancer (CRC) and follow-up with a colonoscopy if needed, a new study has found.

The study also found a similar low 3% rate of CRC detected at colonoscopy in both the younger and older adults.

“Our study suggests that adults ages 45-49 have a colorectal cancer risk that is similar to what we see in adults age 50,” senior author Jeffrey K. Lee, MD, MPH, gastroenterologist and research scientist at Kaiser Permanente Northern California Division of Research (DOR) in Oakland, California, said in a news release.

“The low number of cancers we found also provides support for initially offering younger adults a non-invasive test, like FIT, to determine which patients would benefit from a colonoscopy,” Lee noted.

Timely and Important Question

“This study addresses a timely and important clinical question, namely, is FIT an acceptable screening modality in patients aged 45-49,” Ziad F. Gellad, MD, MPH, AGAF, professor of medicine, Duke University Medical Center, Durham, North Carolina, who was not involved in the study, said in an interview.

“The finding that FIT completion and yield in younger patients is similar to those aged 50 and above is good news because it supports the use of this screening modality in the younger cohort,” said Gellad, section chief, gastroenterology, Durham VA Health Care System.

FIT First Fits With Younger Adults’ Busy Lives

“Overall, people under 50 have lower incidence of cancer than people in their 50s, 60s, and 70s. However, if you do a test like FIT first, you can improve the yield of colonoscopy, which is a much more efficient strategy,” Levin said.

He noted that younger people are the least likely to be screened.

“They are busy with work and family responsibilities and may not realize that they are at risk for CRC. It is important to offer them a test that is easy to perform and does not require them to miss a day of work or arrange for a driver. They should be offered an option to screen with a stool-based test as an easy way to fit CRC screening into their busy lives,” Levin said.

Gellad said the study also highlights the limitations of FIT, “namely, that the low uptake and suboptimal colonoscopy follow-up of positive tests, also extend into the lower age group.”

Additionally, Gellad said he hopes other large systems will replicate this study to address the generalizability of these findings outside the Kaiser system.

The study was funded by the Kaiser Permanente Sydney R. Garfield Memorial Fund. Disclosures for study authors are available with the original article. Gellad consulted for Merck & Co. and Novo Nordisk and is a co-founder of Higgs Boson, Inc.

Gellad said the study also highlights the limitations of FIT, “namely, that the low uptake and suboptimal colonoscopy follow-up of positive tests, also extend into the lower age group.”

Additionally, Gellad said he hopes other large systems will replicate this study to address the generalizability of these findings outside the Kaiser system.

The study was funded by the Kaiser Permanente Sydney R. Garfield Memorial Fund. Disclosures for study authors are available with the original article. Gellad consulted for Merck & Co. and Novo Nordisk and is a co-founder of Higgs Boson, Inc.

VIENNA — A diet high in ultraprocessed foods (UPFs) increases the risk for clinical relapse in patients with Crohn’s disease (CD) who are in remission, results of a new study suggested.

Certain subgroups of UPFs, specifically bread, pastries, and starch as well as oil and spreads, exhibited the strongest association with relapse risks of approximately threefold.

“In addition to treating active inflammatory bowel disease (IBD), we want to maintain remission for the long term,” Chen Sarbagili Shabat, PhD, clinical dietitian from Tel Aviv Medical Center in Israel, said in an interview. “It’s highly important. We know environmental factors are associated with the disease, which is why we can treat active disease with diet. Likewise, we can manage CD in a remission state with diet.”

This is the first prospective study of this particular level of UPFs in people with Crohn’s disease who are in remission, noted Shabat, who presented the findings at United European Gastroenterology (UEG) Week 2024.

Previously, a meta-analysis of prospective cohort studies showed that a diet high in UPFs is associated with a 70% increased risk for development of CD, and a longitudinal study showed that “Western” dietary patterns were associated with relapse risk in patients with IBD, Shabat reported.
 

Effect of High vs Low Intake of UPFs

The current single-center, prospective cohort study, followed 111 patients with CD every 3 months until relapse for up to 1 year.

Participants were aged 18-75 years (mean age, 38 years), with a median disease duration of 8.7 years. They were required to have maintained steroid-free clinical remission (Harvey-Bradshaw Index (HBI), < 5) for 3 months or more. The median duration of clinical remission at recruitment was 3 years.

Data collection included HBI level, medication type and dosage to ensure constant therapy and full compliance, and a stool sample for fecal calprotectin measurement.

The primary outcome comprised a clinical relapse HBI ≥ 5 over the 12-month follow-up or a change in disease activity requiring a change in medication, hospitalization, or any IBD-related surgery.

Participants were asked to complete a processed food questionnaire to assess the intake of UPFs and a food frequency questionnaire to assess the total intake of energy, macronutrients, and micronutrients. UPFs were divided into high and low intakes using a median cutoff of 3.6 servings/day.

The low intake group included 57 participants, and the high intake group included 54.

A total of 24 patients (21.6%) experienced a clinical relapse event, 7 in the low intake group vs 17 in the high intake group (hazard ratio [HR], 3.86; 95% CI, 1.30-11.47; P = .015 after adjustments).

In a subset of 97 patients with baseline fecal calprotectin measurements, 6 (n = 50) in the low intake group experienced a clinical relapse vs 15 (n = 47) in the high intake group (HR, 4.32; 95% CI, 1.36-13.73; P = .013 after adjustments).

Fecal calprotectin results were also suggestive of an association between high intake of UPFs and gut inflammation, Shabat reported.
 

Food Groups and Emulsifiers

UPFs were divided into subgroups: Bread, pastries, and starch; oils and spreads; ultraprocessed meat; sweet products and desserts; and ultraprocessed beverages.

The highest associations with relapse were in the subgroup of bread, pastries, and starch (HR, 3.37; 95% CI, 1.26-8.25) and the subgroup of oils and spreads (HR, 2.76; 95% CI, 1.02-7.45).

“The selection of healthy food is highly important, especially since we know that certain food ingredients can contribute to the pathogenesis of CD,” Shabat said. Patients can use partial enteral nutrition to provide 40%-50% of daily caloric intake in order to maintain remission, but she acknowledged it can be really difficult to adhere to.

She concluded by asserting that the study results, along with future research, should contribute to establishing nutritional guidelines to reduce UPF consumption in patients with CD in order to maintain remission.

Commenting on the study, Kevin Whelan, PhD, professor of dietetics and head of the Department of Nutritional Sciences at King’s College London in England, said that he was intrigued by the subgroup analysis that showed breads, pastries, oils, and spreads as having the strongest association with relapse risk.

He also remarked that these foods almost ubiquitously contain emulsifiers, and so the association might have less to do with UPFs in general and more to do with emulsifiers.

Concurring, Shabat noted that, while emulsifiers can negatively influence the microbiota and the gut barrier function, as well as contribute to intestinal inflammation, further mechanistic studies are required to understand these effects.

We need to determine if all additives have the same effect on the inflammatory process and also need studies looking at UPFs alone, she added.

Shabat reported receiving personal fees from Nestle Health Science (Wolfson Medical Center IP) for consulting and speaking and from Takeda and Ferring for speaking. Whelan reported no relevant disclosures.

Last April, the US Preventive Services Task Force (USPSTF) revised its breast cancer screening guidelines to recommend average-risk women start their screening mammograms at age 40, instead of age 50, and continue every other year until age 74. 

The USPSTF’s recent recommendations align with those from major organizations, including the National Comprehensive Cancer Network and the American College of Radiology. The latest update comes from the American College of Obstetricians and Gynecologists (ACOG), which recommended a start age of 40 and continued screening either annually or every 2 years.

For USPSTF, the decision to recommend the earlier screening age, instead of keeping the choice an individualized one, was largely driven by the steady rise in breast cancer diagnoses among women in their 40s, alongside evidence that Black women are more likely to get breast cancer younger and die from the disease compared with White women. 

But is this recommendation to screen earlier a change for the better? 

Opinions vary.

USPSTF member John Wong, MD, chief of clinical decision making and a primary care physician at Tufts Medical Center in Boston, believes the new recommendation is the right move.

“It is now clear that screening every other year starting at age 40 has the potential to save about 20% more lives among all women and there is even greater potential benefit for Black women, who are much more likely to die from breast cancer,” Wong told Medscape last year. 

However, in a recent Viewpoint in JAMA Internal Medicine, experts from the University of California San Francisco expressed their reservations about shifting the recommended screening age a decade earlier.

The trio — Karla Kerlikowske, MD, Laura Esserman, MD, and Jeffrey Tice, MD — called the new recommendations “surprising” given the lack of new randomized control trial data to support the change as well as data that show breast cancer deaths have been decreasing among women, including younger women. 

More specifically, breast cancer deaths for women under 50 have decreased from 5.9 to 3.9 per 100,000 individuals between 2000 and 2020 — a decline that can likely be attributed to better treatments rather than increased screening effectiveness, the Viewpoint authors said.

However, moving the screening age earlier would not markedly improve survival for most women, the authors argued. According to USPSTF modeling, starting mammograms at age 40 instead of 50 could avert only 1.3 additional breast cancer deaths per 1000 women screened biennially and 1.8 additional breast cancer deaths among Black women.

Starting screening at 40, however, does come with an array of potential harms. These include 65 more benign biopsies per 1000 women screened, 1 in 2 women with a false-positive mammography result (503 per 1000), and 1 in 500 women with an over-diagnosed breast cancer, meaning the cancer would not have become clinically evident in their lifetime. 

The use of digital breast tomosynthesis can slightly reduce the number of false-positives and benign biopsies compared to older mammography techniques, but these small improvements did not sway the overall pro-con assessment for the Viewpoint authors.

“False-positive results require additional imaging and are associated with anxiety for patients,” the authors noted. “Women who have benign biopsies may experience the potential adverse effects of biopsies, such as bleeding, infection, and scarring unnecessarily; and over-diagnosis may lead to unnecessary treatment.”

Kenneth Lin, MD, MPH, family physician and associate director of the Lancaster General Hospital Family Medicine Residency in Pennsylvania, agreed that starting mammograms at age 40 is not a change for the better. 

Lin and colleagues conducted an analysis based on data from the USPSTF’s 2016 breast cancer screening report that similarly found 1 additional breast cancer death prevented per 1000 women screened starting at 40 vs 50, at a cost of 576 more false-positive results, 67 more benign breast biopsies, and 2 women diagnosed and treated unnecessarily. 

Overall, “there is no compelling evidence to change our clinical approach to breast cancer screening for women in their 40s: individual decision-making based on patient preferences and values,” Lin wrote in a recent Medscape commentary. 

But several experts not involved in the USPSTF recommendations agree with the change. 

The updated recommendation to begin mammograms at age 40 for women at average risk “aligns with accumulating data suggesting that earlier and more frequent screening can save more lives, and is widely seen as a positive step,” said Lisa Abramson, MD, a radiologist specializing in breast imaging with Mount Sinai Health System and Icahn School of Medicine at Mount Sinai, New York City.

Melissa Fana, MD, a breast surgical oncologist at NYU Langone Health, agreed that the revised recommendation is justified and “will undoubtedly save lives.” 

“The recent change in the screening recommendation was meant to be inclusive, and provide women, particularly women aged 40 to 49 the opportunity to screen with mammography,” Fana said.

One major argument in favor of earlier screening is that it will help address racial inequities in breast cancer diagnoses, treatment, and deaths. Despite a 5% lower incidence of breast cancer, Black women are more likely to be diagnosed with distant-stage cancer or more aggressive breast cancer subtypes, such as triple-negative, compared with White women, and are more likely to die from breast cancer.

“We hope that the earlier initiation of mammography screening across the board will have a great net benefit in outcomes for Black women especially, who have been shown to have the poorest outcomes when it comes to breast cancer, in part because of long-standing inequities in social determinants of health,” said Cherie C. Hill, MD, FACOG, an ob.gyn. at Emory Healthcare in Atlanta, who coauthored the recent ACOG recommendations.

The Viewpoint authors Kerlikowske, Esserman and Tice agreed that Black women may benefit more from earlier screening. However, earlier screening does not address the underlying disparities in treatment and follow-up care for Black women, and it is unclear whether screening alone will help improve breast cancer mortality rates for Black women, the authors noted.

There is one place where experts seem to align: the importance of educating patients about their personal risk. 

The Viewpoint authors favor a risk-based approach to help women decide whether to start screening before age 50. 

“Engaging women in informed decision-making based on their invasive and advanced breast cancer risk would be a patient-centered approach toward tailored screening, informing when to consider starting screening and how often to screen,” the experts wrote. 

For a woman to truly make an educated decision on whether she would like to screen or wait after age 40, she would at least need to know what her specific lifetime risk of developing breast cancer is, not the average risk is for American women in general, Fana told this news organization. 

“Risk assessment calculators are widely available and include factors such as family history and reproductive history, and this information can evolve over time and affect lifetime risk,” Fana noted. But “some women just do not get this information.”

Abramson explained that ob.gyns. and primary care physicians will likely play a larger role in the early assessment of breast cancer risk, including discussions about genetic testing and personal risk factors starting as early as age 25. 

“For clinicians, the emphasis may be on educating patients about their individual risk, ensuring timely mammograms, and referring higher-risk individuals for further testing or consultations with specialists,” Abramson added. 

Esserman reported being a Blue Cross Medical Advisory Panel member, an uncompensated board member of Quantum Leap Healthcare Collaborative, which funds the I-SPY trial through the University of California, San Francisco, and having an investigator-initiated trial for high-risk ductal carcinoma in situ (DCIS) funded through UCSF by Moderna for a DCIS phase 1 study. Tice and Kerlikowske reported receiving grants from the National Cancer Institute outside the submitted work. Abramson and Fana have no relevant disclosures.

The use of digital breast tomosynthesis can slightly reduce the number of false-positives and benign biopsies compared to older mammography techniques, but these small improvements did not sway the overall pro-con assessment for the Viewpoint authors.

“False-positive results require additional imaging and are associated with anxiety for patients,” the authors noted. “Women who have benign biopsies may experience the potential adverse effects of biopsies, such as bleeding, infection, and scarring unnecessarily; and over-diagnosis may lead to unnecessary treatment.”

Kenneth Lin, MD, MPH, family physician and associate director of the Lancaster General Hospital Family Medicine Residency in Pennsylvania, agreed that starting mammograms at age 40 is not a change for the better. 

Lin and colleagues conducted an analysis based on data from the USPSTF’s 2016 breast cancer screening report that similarly found 1 additional breast cancer death prevented per 1000 women screened starting at 40 vs 50, at a cost of 576 more false-positive results, 67 more benign breast biopsies, and 2 women diagnosed and treated unnecessarily. 

Overall, “there is no compelling evidence to change our clinical approach to breast cancer screening for women in their 40s: individual decision-making based on patient preferences and values,” Lin wrote in a recent Medscape commentary. 

But several experts not involved in the USPSTF recommendations agree with the change. 

The updated recommendation to begin mammograms at age 40 for women at average risk “aligns with accumulating data suggesting that earlier and more frequent screening can save more lives, and is widely seen as a positive step,” said Lisa Abramson, MD, a radiologist specializing in breast imaging with Mount Sinai Health System and Icahn School of Medicine at Mount Sinai, New York City.

Melissa Fana, MD, a breast surgical oncologist at NYU Langone Health, agreed that the revised recommendation is justified and “will undoubtedly save lives.” 

“The recent change in the screening recommendation was meant to be inclusive, and provide women, particularly women aged 40 to 49 the opportunity to screen with mammography,” Fana said.

One major argument in favor of earlier screening is that it will help address racial inequities in breast cancer diagnoses, treatment, and deaths. Despite a 5% lower incidence of breast cancer, Black women are more likely to be diagnosed with distant-stage cancer or more aggressive breast cancer subtypes, such as triple-negative, compared with White women, and are more likely to die from breast cancer.

“We hope that the earlier initiation of mammography screening across the board will have a great net benefit in outcomes for Black women especially, who have been shown to have the poorest outcomes when it comes to breast cancer, in part because of long-standing inequities in social determinants of health,” said Cherie C. Hill, MD, FACOG, an ob.gyn. at Emory Healthcare in Atlanta, who coauthored the recent ACOG recommendations.

The Viewpoint authors Kerlikowske, Esserman and Tice agreed that Black women may benefit more from earlier screening. However, earlier screening does not address the underlying disparities in treatment and follow-up care for Black women, and it is unclear whether screening alone will help improve breast cancer mortality rates for Black women, the authors noted.

There is one place where experts seem to align: the importance of educating patients about their personal risk. 

The Viewpoint authors favor a risk-based approach to help women decide whether to start screening before age 50. 

“Engaging women in informed decision-making based on their invasive and advanced breast cancer risk would be a patient-centered approach toward tailored screening, informing when to consider starting screening and how often to screen,” the experts wrote. 

For a woman to truly make an educated decision on whether she would like to screen or wait after age 40, she would at least need to know what her specific lifetime risk of developing breast cancer is, not the average risk is for American women in general, Fana told this news organization. 

“Risk assessment calculators are widely available and include factors such as family history and reproductive history, and this information can evolve over time and affect lifetime risk,” Fana noted. But “some women just do not get this information.”

Abramson explained that ob.gyns. and primary care physicians will likely play a larger role in the early assessment of breast cancer risk, including discussions about genetic testing and personal risk factors starting as early as age 25. 

“For clinicians, the emphasis may be on educating patients about their individual risk, ensuring timely mammograms, and referring higher-risk individuals for further testing or consultations with specialists,” Abramson added. 

Esserman reported being a Blue Cross Medical Advisory Panel member, an uncompensated board member of Quantum Leap Healthcare Collaborative, which funds the I-SPY trial through the University of California, San Francisco, and having an investigator-initiated trial for high-risk ductal carcinoma in situ (DCIS) funded through UCSF by Moderna for a DCIS phase 1 study. Tice and Kerlikowske reported receiving grants from the National Cancer Institute outside the submitted work. Abramson and Fana have no relevant disclosures.

VIENNA — Cendakimab, a monoclonal antibody targeting interleukin (IL) 13, improved symptoms and reduced esophageal eosinophil counts in adult and adolescent patients with eosinophilic esophagitis (EoE), according to interim results of a pivotal phase 3 trial.

Treatment with cendakimab also improved key endoscopic and histologic features, even in patients who had an inadequate response or intolerance to steroids, reported Alain Schoepfer, MD, gastroenterologist from Centre Hospitalier Universitaire Vaudois and University of Lausanne, in Switzerland.

The drug was generally safe and well tolerated up to 24 weeks of treatment, added Schoepfer, who presented the results during a presentation at the United European Gastroenterology (UEG) Week 2024.
 

Targeting IL-13 Shows ‘Surprisingly Good Results’

EoE is a chronic, progressive, immune-mediated, inflammatory disease that is mainly driven by the cytokine, IL-13.

In a prior phase 2 study, cendakimab, which selectively binds to IL-13 and blocks its interaction with both the IL-13Ra1 and the IL-13Ra2 receptors, was shown to improve symptoms and endoscopic features of EoE.

For the current phase 3 trial, participants were required to have a peak eosinophil count (PEC) of ≥ 15 eosinophils (eos)/high power field (hpf) and 4 or more days of dysphagia over the 2 weeks prior to the start of the study. In addition, they had to have shown a complete lack of response to proton pump inhibitor (PPI) treatment for 8 weeks or more.

A total of 430 patients were randomized 1:1:1 to subcutaneous cendakimab (360 mg) once weekly for 48 weeks; subcutaneous cendakimab (360 mg) once weekly for 24 weeks, then once every 2 weeks for a further 24 weeks; or subcutaneous placebo once weekly for 48 weeks.

Patient characteristics were similar across randomization groups. The majority of participants were men, with a mean age of 35 years (range, 12-75 years); adolescents comprised 6%-11% of the total. The disease duration was around 5-6 years for all participants, of which 45% were on a stable PPI dosage and around 65% had steroid intolerance or an inadequate response. The endoscopic reference score was around 10 across all groups. The mean PEC was around 160 eos/hpf in the cendakimab arms vs 200 eos/hpf in the placebo arm.

Schoepfer reported results for the coprimary endpoints — the mean change from baseline in dysphagia days and the proportion of patients with eosinophil histologic response (PEC ≤ 6 eos/hpf) — at week 24. At this point, a total of 286 patients had received treatment with 360 mg of cendakimab once weekly, and 143 had received placebo.

The change in dysphagia days was −6.1 in patients on cendakimab once weekly vs −4.2 in patients on placebo (P = .0005). The proportion of patients with eosinophil histologic response was 28.6% in the treatment arm vs 2.2% in the placebo arm.

The results were similar for patients who were classified as having had a steroid inadequate response. The change in dysphagia days was −6.3 in the cendakimab group vs −4.7 in the placebo group (P = .0156). The eosinophil histologic response was 29.5% in the treatment group vs 2.1% in the placebo group (P < .0001).

Endoscopic response, a key secondary endpoint, showed a change from baseline to week 24 in the endoscopic features of EoE. The total endoscopic reference scores were −5.2 for patients on cendakimab once weekly and −1.2 for patients on placebo (P < .0001).

The safety profile of cendakimab was “unspectacular,” Schoepfer said, with adverse events related to the study drug occurring in 30% of patients in the treatment arm vs 18.9% of those in the placebo arm. He noted that as the trial was conducted during the COVID pandemic, there were some infections.

Serious adverse events, which were assessed by investigators to not be related to the study drug, occurred in 1.8% and 2.8% of patients on cendakimab and placebo, respectively. Drug discontinuation occurred in 1.4% in the cendakimab group and 0.7% in the placebo group. There were no deaths.

“We really need drugs for this disease, given that there are very few alternatives to steroids and PPIs,” Co-moderator Ram Dickman, MD, Division of Gastroenterology, Rabin Medical Center, Petah Tikva, Israel, said in an interview.

Right now, we have dupilumab, which targets two receptors: IL-4 and IL-13. But targeting IL-13 by itself “is showing surprisingly good results,” so cendakimab is a good candidate to be in “the first line of biologic treatments,” Dickman said.

“It’s safe and works rapidly,” he added. “Given this is a phase 3 study, I believe we’ll see it on the market.”

Schoepfer has served as a consultant for Regeneron/Sanofi, Adare/Ellodi, AbbVie, AstraZeneca, Celgene/Receptos/Bristol Myers Squibb, Dr. Falk Pharma, Gossamer Bio, GSK, Janssen, MSD, Pfizer, Regeneron/Sanofi, Takeda, and Vifor; received grant/research support from Adare/Ellodi, Celgene/Receptos/Bristol Myers Squibb, GSK, and Regeneron/Sanofi. Dickman has declared no relevant disclosures.

A new consensus statement from the American Diabetes Association provides advice on the use of continuous glucose monitoring (CGM) systems in hospital settings, based in part on data collected during the COVID-19 pandemic.

The statement, Consensus Considerations and Good Practice Points for Use of Continuous Glucose Monitoring Systems in Hospital Settings, was published on October 25, 2024, in Diabetes Care.

“This is something that requires close collaboration with many groups in the hospital ... There needs to be really good guidance within the hospital as to when it can be used, in which patients, and what checks and balances need to be in place,” statement lead author Julie L.V. Shaw, PhD, Laboratory Director at Renfrew Victoria Hospital and St. Francis Memorial Hospital, Ottawa, Ontario, Canada, told this news organization.

CGM use in the outpatient setting continues to grow, among people with type 2 as well as type 1 diabetes. The devices are worn on the body for up to 15 days via a subcutaneously-inserted sensor that detects glucose in interstitial fluid every 1-15 minutes. The readings generally track with blood glucose levels, although discrepancies can occur and may be even more relevant in hospital settings.

About 1 in 4 hospitalized patients have diabetes and/or hyperglycemia. During the COVID-19 pandemic, the US Food and Drug Administration (FDA) and Health Canada temporarily authorized the use of CGM systems in hospitals to supplement point-of-care glucose testing, as an emergency measure to reduce healthcare worker exposure and preserve personal protective equipment. That FDA authorization expired on November 7, 2023, and currently hospital CGM use in the United States is technically off-label, although it is often allowed for patients who already use CGM systems.

The new statement summarizes clinical study data and also addresses the potential benefits of CGM systems for inpatients, existing guidance, analytical and clinical evaluation of CGM performance, safety factors, staff training, clinical workflow, and hospital policies. Also covered are issues around quality assurance, integration of CGM data into electronic health records, cost considerations, and barriers to implementation.

The “good practice points for consideration” in the document are as follows:

• If healthcare professionals want to use CGM systems beyond their intended use, eg, to replace or reduce point-of-care glucose measurements, analytical and clinical performance should be assessed.
• The Clinical and Laboratory Standards Institute (CLSI) 2nd Edition of POCT05 — Performance Metrics for Continuous Interstitial Glucose Monitoring provides helpful guidance.
• Potential interferences that preclude patients from being eligible for CGM should be noted, and staff must be aware that CGM can’t be used for clinical decision-making in these patients.
• A CGM system and/or inpatient glycemia management committee should oversee the development and implementation of hospital-approved policies and procedures for CGM use in the hospital. This committee should have representatives from nursing leadership, physician leadership (e.g., endocrinologists, internal medicine specialists, hospitalists), laboratory, information services, hospital administration, pharmacy, and risk management/legal.
• Policies for patient-owned and hospital-owned CGM devices should be developed, and staff should be trained in their use.

“During the pandemic, there was a lot of research on CGM use in the hospital setting, so we could look at how it works and was it safe. I think we have some good data to show where it can be used,” said Shaw, who also heads the Division of Biochemistry at the Ottawa Hospital. She added, “There’s quite a bit we still don’t know, but I think with some guidance in place about when not to use it, there are certainly patient populations who could benefit from it in the hospital setting.” 

Shaw had no disclosures. Another author is general manager and medical director of the Institute for Diabetes Technology (IfDT), which carries out clinical studies, eg, with medical devices for diabetes therapy, on its own initiative and on behalf of various companies. Another author is an IfDT employee. Other authors have received speakers’ honoraria or consulting fees in the last 3 years from Abbott, Berlin-Chemie, BOYDSense, Dexcom, Lilly Deutschland, Novo Nordisk, Perfood, PharmaSens, Roche, Sinocare, Terumo, and Ypsomed.

A group of researchers from the University of Pennsylvania, Philadelphia, has developed a messenger RNA (mRNA) vaccine, delivered via lipid nanoparticles (LNPs) — the same type as the COVID-19 vaccine produced by Moderna and Pfizer — targeting Clostridioides difficile (formerly Clostridium difficile). According to the authors, the results of their preclinical study, published in Science, demonstrated this technology as a promising platform for C difficile vaccine development and could be the starting point for curbing intestinal infections that, in their most severe forms (pseudomembranous colitis, toxic megacolon), can be fatal.

An Increasingly Pressing Issue

C difficile is the leading cause of infectious diarrhea acquired in healthcare settings. In recent years, community-acquired C difficile infections have also become more frequent. The increase in infections has been attributed to the emergence of highly virulent and antibiotic-resistant strains.

A 2019 study reported a global incidence of C difficile infections at 2.2 per 1000 hospital admissions per year and 3.5 per 10,000 patient-days per year.
 

The Vaccine Candidate

Vaccine candidates tested so far have used toxoids or recombinant proteins targeting the combined repetitive oligopeptide (CROP) or receptor-binding domain (RBD) of the two primary C difficile toxins, TcdA and TcdB. The US researchers are now exploring the mRNA-LNP vaccine approach to target multiple antigens simultaneously. They developed a bivalent vaccine (including the CROP and RBD domains of both toxins) and a trivalent vaccine (with an additional virulence factor, the metalloprotease Pro-Pro endopeptidase-1).

Mice vaccinated with the bivalent and trivalent vaccines produced immunoglobulin G antibody titers two to four times higher than those elicited by recombinant protein with an adjuvant. The vaccination stimulated the proliferation of follicular T helper cells and the antigen-specific response of B lymphocytes, laying the foundation for a strong and long-lasting humoral response. The vaccines were also immunogenic in hamsters.

Vaccinated mice not only survived a toxin dose five times higher than the 100% lethal dose but also demonstrated the vaccine’s protective effect through serum transfer; unvaccinated mice given serum from vaccinated mice survived the lethal challenge. More importantly, when exposed to a lethal dose of the bacterium itself, all vaccinated mice survived.

To demonstrate the vaccine’s efficacy in patients with a history of C difficile infection and high recurrence risk — ideal candidates for vaccination — the researchers vaccinated mice that had previously survived a sublethal infection. Six months after the initial infection and vaccination, these mice remained protected against mortality when reexposed to the bacterium.

Additionally, a quadrivalent vaccine that included an immunogen targeting C difficile spores — key agents in transmission — also proved effective. Low levels of bacteria and toxins in the feces of mice vaccinated in this way suggested that spore vaccination could limit initial colonization.

In tests with nonhuman primates, two doses of the vaccines targeting either the vegetative form or the spores elicited strong immune responses against bacterial toxins and virulence factors. Human trials may indeed be on the horizon.

A novel digital treatment designed to reduce the frequency of auditory hallucinations and associated distress in patients with psychosis has been shown to be safe and effective, results from the largest study of avatar therapy to date show. 

The therapy allows patients to interact with a “digital embodiment” of the voice they hear, which is represented by a computer-generated face, also known as an avatar.

In the randomized, multisite, phase 2/3 AVATAR2 trial, patients who received AVATAR-Extended therapy, which included a personalized series of voiced dialogues based on their life history, plus treatment as usual (TAU) showed significantly greater improvement in distress and voice severity levels at 16 weeks vs those who received TAU only. They also had significant reductions in voice frequency at 16 and 28 weeks.

Patients in a third arm who were assigned to TAU plus AVATAR-Brief therapy, which included six sessions of a standardized version of the therapy, also showed improvements at 16 weeks, compared with TAU alone — but the clinical impact was stronger with the extended version. 

“I was surprised at the extent to which the extended version seemed to be a more optimal version, and it should be the way forward with this therapy,” said study investigator Philippa A. Garety, PhD, professor emerita of clinical psychology at the Institute of Psychiatry, Psychology, and Neuroscience at King’s College, London, England.

With more than 300 participants, AVATAR2 is the largest trial to access avatar therapy to date, Garety noted.

“What’s unique about this work is that technology allows us to create safe face-to-face encounters with a representation of a person’s voice and allows them to relate to that voice in a new way,” she added. 

The findings were published online in Nature Medicine. 
 

A Decade of Research

Auditory verbal hallucinations are common in patients with schizophrenia, but currently available therapies can be ineffective, investigators wrote. 

The therapy allows patients to customize how the avatar looks and sounds. Face-to-face dialogues are then conducted between the patients and avatars in order to build empowerment. A trained therapist provides support during these sessions.

As previously reported, the creator of avatar therapy, Julian Leff, MD, presented promising results from a pilot study of 26 patients at the International Congress of the Royal College of Psychiatrists in 2014. 

“Opening up a dialogue between a patient and the voice they’ve been hearing is powerful,” said Leff, who was emeritus professor at the Institute of Psychiatry in London at the time.

In 2018, a randomized single-site study (AVATAR1) of 150 participants showed that the intervention was associated with a greater decrease in voice severity at 12 weeks vs supportive therapy. Past research led to the idea of incorporating personalization to better optimize the experience. 

Garety noted that AVATAR2 is the largest trial to date of the therapy, as well as the first multisite trial to test the intervention, which was important in order to determine whether it could work outside of a research setting. 

The study included 345 participants (61.4% men; mean age, 39.6 years) from three sites in England and one in Scotland. All were randomly assigned to receive TAU alone (n = 115), TAU plus AVATAR-Brief (n = 116), or TAU plus AVATAR-Extended (n = 114). 

TAU typically included use of antipsychotics, as well as outpatient psychiatric visits and follow-up by case managers and care coordinators. 

“We didn’t interfere with treatment as usual. We wanted to test whether adding this therapy to [TAU] would enhance effects and provide better treatment for their voices,” Garety noted. 

AVATAR-Brief included a standardized process that focused on such things as self-esteem and assertiveness. AVATAR-Extended had two phases. In the first, participants received AVATAR-Brief therapy, whereas the second phase offered a more personalized intervention.
 

An ‘Unusual Finding’ 

The study’s primary outcome was voice-related distress at 16 and 28 weeks. Although the TAU plus AVATAR-Extended group did show a significant decrease in distress at 16 weeks vs TAU alone (–1.6 points; P = .029), the improvement was no longer significant at the 28-week follow-up (P = .175). The same was also true for the key secondary outcome of reduction in voice severity (–2.32 points; P = .009 at 16 weeks but P =.1 at 28 weeks).

The investigators noted that this might be caused by the number of dropouts in the AVATAR-Extended group by the 28-week timepoint. The completion rate for those patients was only 58%. The completion rate for the shorter, AVATAR-Brief group was 82%.

On the other hand, the other key secondary outcome of voice frequency was significantly reduced with AVATAR-Extended at both 16 weeks (–0.62 point; P = .01) and 28 weeks (–0.89 point; P = .003).

“This is an unusual finding. We’re not aware of any other psychological therapy that shows a reduction in the occurrence of the voice,” Garety said. 

For TAU plus AVATAR-Brief, there were improvements at 16 weeks for distress (-1.05 points; P = .035) vs TAU alone. However, the researchers noted that this version of the therapy was just below the prespecified threshold for a clinically significant change and was at the threshold for statistical significance. 

Although the shorter therapy was associated with a reduction in voice severity level at 16 weeks (–2.04 points; P = .017) vs TAU alone, there was no reduction in distress or voice severity at 28 weeks. There was no improvement in voice frequency at either timepoint. 

Both the brief and the extended versions of AVATAR therapy showed improved mood and anxiety levels at 16 weeks and sustained improvement in well-being and recovery, the researchers noted.

“The short version, as expected, did deliver benefits posttreatment, but clearly the extended, optimized version outperformed the brief version. It had stronger and more lasting effects across quite a wide range of outcomes that matter to people who hear voices,” Garety said. 

“In the extended version, people felt more empowered. And in just that version, the frequency of voices was reduced, which is a very important outcome,” she added. 
 

Safety Issues?

There were 58 serious adverse events (SAEs) in total, with 51% of those occurring in the AVATAR-Extended group. Two participants in that group died; however, independent reviews deemed these events as not related to the intervention. 

In addition, there were no “definitely related” SAEs and only a small number of “possibly related” SAEs, which typically included hospitalization with other contributory factors.

Garety noted during a press briefing that AVATAR therapy has now been demonstrated to be safe across two large trials. 

Study limitations cited included no direct comparison between AVATAR-Brief and AVATAR-Extended or between AVATAR therapy and a different type of psychological treatment. 

Overall, “we recommend that future development and provision of AVATAR therapy is primarily guided” by the AVATAR-Extended protocol, the investigators wrote.

Because the therapy was recommended by a National Institute for Health and Care Excellence Early Value Assessment, the investigators are now seeking to provide it in routine National Health Service settings to gather further real-world evidence of effectiveness over the next 3 years.
 

Next Steps

Although the intervention isn’t currently available to everybody who might be seeking it, “there’s a pipeline of movement from research into treatment and it’s moving towards the next stage of delivery,” Garety said. 

Investigators are also looking into cultural adaptations for the therapy so it can be used in different locales, including Ethiopia and India, she added. There isn’t a US version yet, but Garety noted that investigators in Canada are looking at similar research and suspects that will also occur in the United States soon. 

“We’re pioneers in this work, and it now needs to be going international and into services,” she said. “We have had many people who hear voices say what an amazing experience this has been. So, I feel very proud and excited to have been able to be part of this.” 

At the press briefing, Miranda Wolpert, director of mental health at Wellcome, which funded the study, noted that it is encouraging to see the development of a new intervention that could potentially change the lives of patients across the world.

“We know that psychosis can start early in life, stopping people from having the jobs and relationships they want and from achieving the goals they want. This intervention was developed with those people to help them address an issue that really troubles them,” Wolpert said. 

“For me, this represents part of a revolution we are starting to see in terms of mental health interventions and the potential impact on mental health science,” she added. 
 

Digital Placebo Effect?

Commenting on the findings, John Torous, MD, a psychiatrist and director of digital psychiatry at Beth Israel Deaconess Medical Center, Boston, Massachusetts, said there is a need for new treatments for schizophrenia that work with different mechanisms.

“We have a lot of medication studies but not as many innovative therapy studies. I think it’s exciting that the results, at least in the shorter-term outcome, were positive. And I think that’s something that can give people hope in using these new technologies,” said Torous, who is also an assistant professor of psychiatry at Harvard Medical School, Boston, and was not involved with the research. 

Still, he did note some study limitations, including whether there could have been some type of “digital placebo effect” from the therapy. 

“If you tell people they’re getting high-tech advanced digital care, that may have some effect,” he said, adding that “it’s always interesting” to tease out the benefit being delivered by the technology vs the delivery mechanism itself — or some combination of both.

Torous added, though, that it’s very difficult to have a rigorous digital control group. “It’s not necessarily a fault of their study, but it’s something to keep in mind when interpreting what the results are.”

He also noted that he would have liked to have seen a direct comparison between this new kind of psychological therapy vs standard psychological therapy, such as cognitive-behavioral therapy. 

In addition, he wondered about expenses and scalability of the intervention, and whether patients would need to go to a specialized center to undergo treatment. Torous mentioned that a version involving virtual reality could perhaps make this more scalable in the future. 

Overall, he said that what the investigators are currently doing is very innovative. “It’s exciting that we’re talking about the next steps. Giving people new options for psychological therapy that may be effective for their disorders is really wonderful to see,” Torous said. 

The study was funded by the National Institute for Health and Care Research (NIHR), the Wellcome Trust King’s Clinical Research Facility, the NIHR Maudsley Biomedical Research Centre and Maudsley NHS Foundation Trust, King’s College London, the Manchester Biomedical Research Centre, and NHS Research Scotland, as well as by a grant from Wellcome.

Torous reported no relevant financial relationships.

Garety noted that AVATAR2 is the largest trial to date of the therapy, as well as the first multisite trial to test the intervention, which was important in order to determine whether it could work outside of a research setting. 

The study included 345 participants (61.4% men; mean age, 39.6 years) from three sites in England and one in Scotland. All were randomly assigned to receive TAU alone (n = 115), TAU plus AVATAR-Brief (n = 116), or TAU plus AVATAR-Extended (n = 114). 

TAU typically included use of antipsychotics, as well as outpatient psychiatric visits and follow-up by case managers and care coordinators. 

“We didn’t interfere with treatment as usual. We wanted to test whether adding this therapy to [TAU] would enhance effects and provide better treatment for their voices,” Garety noted. 

AVATAR-Brief included a standardized process that focused on such things as self-esteem and assertiveness. AVATAR-Extended had two phases. In the first, participants received AVATAR-Brief therapy, whereas the second phase offered a more personalized intervention.
 

An ‘Unusual Finding’ 

The study’s primary outcome was voice-related distress at 16 and 28 weeks. Although the TAU plus AVATAR-Extended group did show a significant decrease in distress at 16 weeks vs TAU alone (–1.6 points; P = .029), the improvement was no longer significant at the 28-week follow-up (P = .175). The same was also true for the key secondary outcome of reduction in voice severity (–2.32 points; P = .009 at 16 weeks but P =.1 at 28 weeks).

The investigators noted that this might be caused by the number of dropouts in the AVATAR-Extended group by the 28-week timepoint. The completion rate for those patients was only 58%. The completion rate for the shorter, AVATAR-Brief group was 82%.

On the other hand, the other key secondary outcome of voice frequency was significantly reduced with AVATAR-Extended at both 16 weeks (–0.62 point; P = .01) and 28 weeks (–0.89 point; P = .003).

“This is an unusual finding. We’re not aware of any other psychological therapy that shows a reduction in the occurrence of the voice,” Garety said. 

For TAU plus AVATAR-Brief, there were improvements at 16 weeks for distress (-1.05 points; P = .035) vs TAU alone. However, the researchers noted that this version of the therapy was just below the prespecified threshold for a clinically significant change and was at the threshold for statistical significance. 

Although the shorter therapy was associated with a reduction in voice severity level at 16 weeks (–2.04 points; P = .017) vs TAU alone, there was no reduction in distress or voice severity at 28 weeks. There was no improvement in voice frequency at either timepoint. 

Both the brief and the extended versions of AVATAR therapy showed improved mood and anxiety levels at 16 weeks and sustained improvement in well-being and recovery, the researchers noted.

“The short version, as expected, did deliver benefits posttreatment, but clearly the extended, optimized version outperformed the brief version. It had stronger and more lasting effects across quite a wide range of outcomes that matter to people who hear voices,” Garety said. 

“In the extended version, people felt more empowered. And in just that version, the frequency of voices was reduced, which is a very important outcome,” she added. 
 

Safety Issues?

There were 58 serious adverse events (SAEs) in total, with 51% of those occurring in the AVATAR-Extended group. Two participants in that group died; however, independent reviews deemed these events as not related to the intervention. 

In addition, there were no “definitely related” SAEs and only a small number of “possibly related” SAEs, which typically included hospitalization with other contributory factors.

Garety noted during a press briefing that AVATAR therapy has now been demonstrated to be safe across two large trials. 

Study limitations cited included no direct comparison between AVATAR-Brief and AVATAR-Extended or between AVATAR therapy and a different type of psychological treatment. 

Overall, “we recommend that future development and provision of AVATAR therapy is primarily guided” by the AVATAR-Extended protocol, the investigators wrote.

Because the therapy was recommended by a National Institute for Health and Care Excellence Early Value Assessment, the investigators are now seeking to provide it in routine National Health Service settings to gather further real-world evidence of effectiveness over the next 3 years.
 

Next Steps

Although the intervention isn’t currently available to everybody who might be seeking it, “there’s a pipeline of movement from research into treatment and it’s moving towards the next stage of delivery,” Garety said. 

Investigators are also looking into cultural adaptations for the therapy so it can be used in different locales, including Ethiopia and India, she added. There isn’t a US version yet, but Garety noted that investigators in Canada are looking at similar research and suspects that will also occur in the United States soon. 

“We’re pioneers in this work, and it now needs to be going international and into services,” she said. “We have had many people who hear voices say what an amazing experience this has been. So, I feel very proud and excited to have been able to be part of this.” 

At the press briefing, Miranda Wolpert, director of mental health at Wellcome, which funded the study, noted that it is encouraging to see the development of a new intervention that could potentially change the lives of patients across the world.

“We know that psychosis can start early in life, stopping people from having the jobs and relationships they want and from achieving the goals they want. This intervention was developed with those people to help them address an issue that really troubles them,” Wolpert said. 

“For me, this represents part of a revolution we are starting to see in terms of mental health interventions and the potential impact on mental health science,” she added. 
 

Digital Placebo Effect?

Commenting on the findings, John Torous, MD, a psychiatrist and director of digital psychiatry at Beth Israel Deaconess Medical Center, Boston, Massachusetts, said there is a need for new treatments for schizophrenia that work with different mechanisms.

“We have a lot of medication studies but not as many innovative therapy studies. I think it’s exciting that the results, at least in the shorter-term outcome, were positive. And I think that’s something that can give people hope in using these new technologies,” said Torous, who is also an assistant professor of psychiatry at Harvard Medical School, Boston, and was not involved with the research. 

Still, he did note some study limitations, including whether there could have been some type of “digital placebo effect” from the therapy. 

“If you tell people they’re getting high-tech advanced digital care, that may have some effect,” he said, adding that “it’s always interesting” to tease out the benefit being delivered by the technology vs the delivery mechanism itself — or some combination of both.

Torous added, though, that it’s very difficult to have a rigorous digital control group. “It’s not necessarily a fault of their study, but it’s something to keep in mind when interpreting what the results are.”

He also noted that he would have liked to have seen a direct comparison between this new kind of psychological therapy vs standard psychological therapy, such as cognitive-behavioral therapy. 

In addition, he wondered about expenses and scalability of the intervention, and whether patients would need to go to a specialized center to undergo treatment. Torous mentioned that a version involving virtual reality could perhaps make this more scalable in the future. 

Overall, he said that what the investigators are currently doing is very innovative. “It’s exciting that we’re talking about the next steps. Giving people new options for psychological therapy that may be effective for their disorders is really wonderful to see,” Torous said. 

The study was funded by the National Institute for Health and Care Research (NIHR), the Wellcome Trust King’s Clinical Research Facility, the NIHR Maudsley Biomedical Research Centre and Maudsley NHS Foundation Trust, King’s College London, the Manchester Biomedical Research Centre, and NHS Research Scotland, as well as by a grant from Wellcome.

With tens of millions of Euros in the offing, researchers across the European Union have eagerly taken up the gauntlet to find novel interventions for difficult-to-treat mental health and pain conditions. Their target is psychedelics, including classic compounds like psilocybin and atypical ones like ketamine and MDMA. Some of these still carry a stigma as party drugs and spiritual gateways to holotropic experiences.

Twelve groups make up the European College of Neuropsychopharmacology’s psychedelic research network. Along with several affiliates, the groups span nine countries (Denmark, Sweden, Finland, Switzerland, Germany, the Netherlands, the Czech Republic, Greece, and the United Kingdom) and are focused on the use of psychedelic compounds as potential treatments for psychiatric conditions like treatment-resistant depression, addiction, attention-deficit/hyperactivity disorder, anorexia, and obsessive-compulsive disorder.

One of the largest endeavors is PsyPal, a 4-year, randomized controlled trial investigating the potential of psilocybin for treating psychological distress in palliative care patients with life-limiting conditions. PsyPal is the first multisite clinical trial funded by the European Union to explore psychedelic-assisted therapy.

At PsyPal’s helm is Robert Schoevers, MD, PhD, professor of psychiatry and Department Head at University Medical Center Groningen (UMCG), Groningen, the Netherlands, a major hub for psychedelic research.

Schoevers is a bit of a pioneer who said he entered psychedelic research somewhat reluctantly. A decade ago, a colleague showed him a few papers on ketamine and depression. Because UMCG has a large population of patients with treatment-resistant depression, he agreed to do a pilot study. Since then, he has put together an interdisciplinary team of 25 researchers, published numerous papers, and currently has seven studies, including PsyPal, in various stages of progress.

Schoevers is also building a large national consortium that aims to investigate and, if shown effective, implement novel psychiatry treatments much more rapidly and efficiently than current drug development and approval processes, which can take 12 years or longer. He has just secured millions in government funding to start this process.

Next year, Schoevers and his team will decide to test either MDMA for posttraumatic stress disorder (PTSD) or psilocybin for depression in a large clinical trial, with the aim of getting a treatment as near to formal registration as possible. This will involve working with the European Medicines Agency and its Dutch counterpart, talking to experts who are familiar with the US Food and Drug Administration’s rejection of Lykos Therapeutics’ MDMA treatment for PTSD, and working directly with patients through the National Patient Alliance. The team is also talking to insurers and pharma companies.

The ultimate goal is to “see if we can build a platform in the Netherlands that would have a European perspective, serve as a point of entry for researchers with good ideas, and [attract] public funding as well as companies who have interesting compounds we think would be worthwhile to study,” Schoevers said.

His multiple endeavors emphasize a transdisciplinary and transdiagnostic approach he has been honing for decades. He and his colleagues are investigating the clinical, psychological, and neurobiological parallels between different treatment- resistant conditions and seeking to understand how contextual factors might influence patients, experiences, and outcomes.
 

Connecting the Dots

Jens H. van Dalfsen, PhD, a postdoctoral researcher in biological psychiatry, is the principal investigator of another UMCG group looking into the neurobiological mechanisms of major depressive disorder and treatment-resistant depression. His team’s strategy entails an elaborate coordination between the preclinical and clinical research settings.

For example, Sarah Massetti, a PhD candidate in biological psychiatry, is using blood samples collected in clinical trials to investigate the molecular mechanisms underpinning the neuroplasticity and immune-modulating effects produced by psychedelic compounds.

Another line of research spearheaded by Rutger Boesjes, a PhD candidate in biological psychiatry, is exploring the interactions between drugs like ketamine and the circadian system and how they might relate to antidepressant responses in animal models. It could be that the timing of administration of these drugs is relevant, he explained.
 

The Patient Factor

How psychedelics work and in whom is a big question for the UMCG team and across the research landscape.

“When researchers and the general public talk about psychedelics, they frequently refer to how they promote synaptic plasticity and new connections in the brain,” said van Dalfsen. “But traditional compounds also do that. So the ultimate question that we’ve been exploring is whether findings reflect an actual pharmacological effect or if expectancy also plays a role. In other words: How can we explain why psychedelics might or might not be effective in treatment-resistant patients?” he explained.

This is where the connection to the clinical experience becomes paramount and Joost Breeksema, PhD, comes in.

Breeksema divides his time between UMCG research and his role as executive director and co-founder of the Open Foundation, a nonprofit dedicated to advancing scientific psychedelic research. The work he’s doing outside the university is helping to frame the investigations of the wider group.

So far he has conducted two qualitative studies.

One was an off-label study in which patients with treatment-resistant depression were administered esketamine.

The other was a randomized clinical trial in which participants were blinded to a single 10- or 25-mg dose of psilocybin versus a 1-mg psilocybin microdose placebo that is too small to invoke any effects.

A key insight was the degree to which participants were unprepared for the intensity of their experiences, especially with regards to ketamine. Breeksema said the sessions might not have been so intense or negative for some participants had they been informed beforehand to expect the drugs could provoke “quite overwhelming experiences” and had they been accompanied by an experienced guide providing reassurance and support.

The format for the psilocybin trial met part of this criteria. Participants received a micro (placebo), medium, or high dose in a single session accompanied by two trained therapists. They then engaged in two sessions afterward to process their experiences. A single psilocybin experience appeared to be not enough or too much depending on the dose they were assigned and if they had prior experience with the compound.

Trial participants also felt they needed more help making sense of the experience. “This is a common and important theme,” said Breeksema. “Think about it. If you’ve been depressed for 10, 15 years and … you uncover something and break through something that’s been stuck, you need to process it.”

Jeanine Kamphuis, PhD, a psychiatrist and senior researcher at UMCG and one of the trial study co-authors, explained that they want to find a way to identify who will be too overwhelmed by these experiences if the dose should be adjusted or if some time needs to pass between dosing sessions. They also want to spend more time preparing patients for these sessions.

She emphasized that the studies have provided a reality check. “These are not wonder pills or wonder experiences. And in these types of patients, they’re not intended for a personal growth experience,” she said. “You have a patient who is sitting in front of you who seeks therapy and relief from very severe mood complaints, and the suffering is high,” she said, adding that expectancy bias further complicates patient participation and, likely, outcomes.
 

The Challenges

For all the potential and opportunity that psychedelics may hold for treatment, UMCG’s work has underscored some challenges.

The field of psychedelic research is characterized by methodological issues, explained van Dalfsen, such as blinding, expectancy, and overestimation of treatment effects. When looking at efficacy, “Is it the compound or the expectancy and promise? This is why it’s important to study how the drugs differ from each other in their biological effects and why they are or are not effective,” he said.

The team has also experienced issues with trial recruitment.

Martijn Godschalk, MD, a PhD candidate in psychiatry, has been addressing this problem while working on RESET-TRD, a phase 3, randomized controlled trial comparing an oral esketamine drink with electroconvulsive therapy in patients with treatment-resistant depression.

He’s been coordinating with local university hospitals, general hospitals, and municipal healthcare clinics to meet inclusion criteria and ensure the trial has enough power to demonstrate effectiveness. In turn, these sites are able to participate in a trial they wouldn’t normally be involved in due to lack of resources.

But Godschalk said he was concerned that many patients have gotten wind of the hype surrounding psychedelic treatments within psychiatry — a factor that has contributed to recruitment challenges. “There are a lot of patients who are interested in the non-registered drug and don’t necessarily have an interest in the other [control] arm,” he said.

Despite the challenges, the classic psychedelics such as MDMA and psilocybin “seem to catalyze a psychological process that may be harder to get with regular psychotherapies,” said Schoevers.

He remains cautious, noting there are still unanswered questions, such as who are the best candidates for these drugs and whether they might cause harm in certain patients while benefiting others. “I do think that this is the first time in 20 or 30 years that there is a group of potential treatments that would really make a difference.”

Schoevers received grants and other funding from The Netherlands Organisation for Health Research & Development, Horizon 2020, Horizon 2023, the National Institute of Mental Health (USA), UMCG, Stichting tot Steun VCVGZ, Nationaal programma Groningen, Healthcare Innovation Funds, Janssen Pharmaceuticals, Novartis, Compass Pathways, Clexio Biosciences, and GH research.

He’s been coordinating with local university hospitals, general hospitals, and municipal healthcare clinics to meet inclusion criteria and ensure the trial has enough power to demonstrate effectiveness. In turn, these sites are able to participate in a trial they wouldn’t normally be involved in due to lack of resources.

But Godschalk said he was concerned that many patients have gotten wind of the hype surrounding psychedelic treatments within psychiatry — a factor that has contributed to recruitment challenges. “There are a lot of patients who are interested in the non-registered drug and don’t necessarily have an interest in the other [control] arm,” he said.

Despite the challenges, the classic psychedelics such as MDMA and psilocybin “seem to catalyze a psychological process that may be harder to get with regular psychotherapies,” said Schoevers.

He remains cautious, noting there are still unanswered questions, such as who are the best candidates for these drugs and whether they might cause harm in certain patients while benefiting others. “I do think that this is the first time in 20 or 30 years that there is a group of potential treatments that would really make a difference.”

Schoevers received grants and other funding from The Netherlands Organisation for Health Research & Development, Horizon 2020, Horizon 2023, the National Institute of Mental Health (USA), UMCG, Stichting tot Steun VCVGZ, Nationaal programma Groningen, Healthcare Innovation Funds, Janssen Pharmaceuticals, Novartis, Compass Pathways, Clexio Biosciences, and GH research.

Case: An 80-year-old man with advanced Alzheimer’s disease is admitted to the hospital after a fall. He is noted to have coughing spells after drinking liquids. He has a swallowing study done which shows severe slowing of motility in the esophagus.

What do you recommend?

A. Feeding tube

B. Thickened liquids

C. Continue current diet

The correct answer for this patient is to allow them to continue their current diet. They do not need thickened liquids. A feeding tube would not be recommended.¹

So are there any data supporting the widespread use of thickened liquid diets for patients with dysphagia and aspiration?

Multiple clinical guidelines for stroke recommend the use of thickened liquids despite minimal to no evidence of efficacy.² It is a common practice to give patients with advanced dementia thickened liquids, especially in the hospital setting. Does this help?

Makhnevich and colleagues published a cohort study of Alzheimer’s disease patients with dysphagia admitted to the hospital over a 5-year period.³ Almost half of the cohort received a thickened liquid diet; these patients were matched with patients who received a thin liquid diet. There was no significant difference in hospital mortality between the groups that received thick liquids and thin liquids (hazard ratio, 0.92; P = .46). Patients receiving thickened liquids were less likely to be intubated but were more likely to have pulmonary infections.

A 2018 Cochrane review concluded that there was no consensus on immediate and long-term effects of modifying the consistency of fluid for swallowing difficulties in dementia because too few studies have been completed.⁴ So why is this important information or lack of information?

What is so bad about a thickened liquid diet?

Eric Widera, MD, shared in JAMA Internal Medicine his experience along with his hospice and palliative care team of drinking thickened liquids.⁵ He drank only thickened liquids for a 12-hour period. “The challenge was eye-opening. It was the first time I experienced the terrible taste and texture of thickened liquids,” he wrote. He shared some of the risks of thickened liquids: dehydration, poor oral intake, and decreased quality of life.

The bottom line is that there is scant evidence for the benefit of thickened liquids, especially for patients with advanced dementia and dysphagia, and giving thickened liquids is not a benign intervention, because of poor tolerability of the diet.
