SINGAPORE – Treatment with an investigational oral interleukin-23 receptor (IL-23R) antagonist peptide – currently known as JNJ-2113 – significantly improved skin lesions in patients with moderate to severe plaque psoriasis across all doses, compared with placebo, according to results of the FRONTIER 1 trial.

In the 16-week phase 2b study, 255 adults with moderate to severe plaque psoriasis were randomly assigned into six treatment groups: placebo (n = 43), JNJ-2113 25 mg daily (n = 43), 25 mg twice daily (n = 41), 50 mg daily (n = 43), 100 mg daily (n = 43), or 100 mg twice daily (n = 42).

Of those who took the placebo, only 9.3% achieved the study’s primary endpoint of a 75% or greater improvement in the Psoriasis Area and Severity Index (PASI-75) by week 16. This was compared with 78.6% in the group that took the highest dose.

“Additionally, the onset of action was fairly fast: at week 4, more than 20% of patients had achieved PASI 75,” said Robert Bissonnette, MD, CEO of Innovaderm Research in Montreal, who presented the findings during a late-breaker session at the World Congress of Dermatology.

Patients in the remaining groups demonstrated a response that corresponded to dosing level: with 37.2%, 51.2%, 58.1%, and 65.1% achieving PASI-75 in the 25 mg daily, 25 mg twice-daily, 50 mg daily, and 100 mg daily groups, respectively.

“These results are very interesting because in terms of psoriasis treatment, if this is confirmed in phase 3, it would give us an oral alternative that would be selective for IL-23,” said Dr. Bissonnette, referring to the signaling pathway that plays a critical role in the pathogenesis of several immune-mediated inflammatory diseases, including plaque psoriasis.

Although rarely life-threatening, the skin disorder is often intractable to treatment. In recent years, therapies that block IL-23 signaling and downstream inflammatory cytokine production have proven useful. “We have on the market a number of biological agents targeting IL-23 that we use on a regular basis,” said Dr. Bissonnette. “However, there are currently no orally delivered therapies.”

If successful, JNJ-2113 – a first-in-class oral IL-23 antagonist peptide developed by Janssen – could change the treatment paradigm for patients with moderate to severe plaque psoriasis. “When I was first introduced to the concept, I thought it wouldn’t work as it’s a peptide, that it would be digested by the stomach,” he told the audience. “But because of its GI stability and its potency, when you administer it orally, you can detect pharmacological activity.”
 

A well-tolerated alternative

Participants in the FRONTIER 1 trial were on average about 44 years old and weighed 88.9 kg (195 lb). Most had been living with psoriasis for about 18 years, with a total PASI score of 19.05. In addition, 43.1% had been treated with phototherapy in the past, 22% with biologics, and 78.4% with systemics.

PASI 90 and 100 were among some of the secondary outcomes measured. Similar to the primary outcome of PASI 75, all treatment groups demonstrated a statistically significant dose-response in PASI 90, compared with placebo. For those on the highest dose of JNJ-2113, 59.5% and 40.5% achieved PASI 90 and PASI 100, respectively, by week 16. The corresponding figures for those receiving placebo were 2.3% and 0%.

The safety profile for JNJ-2113 across all doses was similar to that of placebo, with no evidence of a dose-dependent increase in the occurrence of adverse events (AEs). The most frequently reported AEs were COVID-19 and nasopharyngitis. There were three serious AEs (COVID-19, infected cyst, suicide attempt) among those on the active drug, but the investigators assessed that they were not related to the study intervention. No deaths, major adverse cardiac events, or malignancies were reported during the study.

Approached for an independent comment, Marius-Anton Ionescu, MD, PhD, from the University Hospital Saint Louis, Paris, who specializes in psoriasis, told this news organization that the new development with JNJ-2113 “is really promising.”

Treatment for plaque psoriasis has improved to the point where some biologics, such as risankizumab (Skyrizi), only require patients to have “four shots a year,” he says. “This is the future of psoriasis treatment; it might go down to two shots a year” – a regimen that will be easier than taking an oral medication once or twice a day.

“But it’s good to have an oral option because you will always have some patients who say: ‘Shots are not for me, I’m afraid,’ ” he says.

However, Dr. Ionescu noted that if JNJ-2113 were to pass phase 3 trials, it might face stiff competition from the selective tyrosine kinase 2 (TYK2) inhibitor deucravacitinib (Sotyktu), which the U.S. Food and Drug Administration approved for use in adults with moderate to severe plaque psoriasis last September. “It has very good results and is the first oral therapy that is comparable with biologics for plaque psoriasis,” he says.

But Dr. Bissonnette remains hopeful for the future. “I think JNJ-2113 goes way beyond psoriasis because this type of strategy using oral peptide–blocking receptors could be used in other immune-mediated diseases, including atopic dermatitis and other diseases outside of dermatology.” In addition to running a phase 3 study for moderate to severe plaque psoriasis, Janssen is planning to initiate a phase 2b clinical trial of JNJ-2113 in adults with ulcerative colitis.

The study was funded by Janssen. Dr. Bissonnette reports consulting and investigating for Janssen, and being on advisory panels and receiving research funding from multiple other pharmaceutical companies. Dr. Ionescu is an investigator for Psoriasis National Register France Psobioteq (no honoraria), and an investigator and speaker for Uriage cosmetics (honoraria).

SINGAPORE – Three oral Janus kinase (JAK) inhibitors – abrocitinib, baricitinib, and upadacitinib – have demonstrated a good treatment response in Asian patients with atopic dermatitis (AD), a small retrospective study conducted in Singapore has found.

“Abrocitinib and upadacitinib surprisingly appeared to have better treatment efficacy compared to baricitinib,” said study lead Yik Weng Yew, MD, PhD, MPH, deputy head of research at Singapore’s National Skin Centre (NSC), who presented the results at the 25th World Congress of Dermatology. “But overall, as a group, I think they show a very good treatment response, as well as a good effect on itch response.”

Sandy Ong

JAK inhibitors are used to treat a variety of inflammatory diseases including alopecia areata, rheumatoid arthritis, and inflammatory bowel disease. Although treatment for severe eczema was previously limited to topical steroids and oral immunosuppressants, there are now two oral JAK inhibitors – abrocitinib and upadacitinib – approved in 2022 by the Food and Drug Administration for treating AD, which affects up to 2.4% of the global population. (A topical formulation of ruxolitinib, a JAK inhibitor, was approved for AD in 2021.)

The Singapore study is one of the few that have examined the safety and efficacy of JAK inhibitors for treatment of AD in a non-White population.
 

Chinese population

For the 12-week trial, conducted in 2022, Dr. Yew and associates recruited 35 patients from the NSC. More than half of participants (64%) were men and most (96%) were of Chinese ethnicity. Four of every five patients had previously received systemic agents: 17% had been treated with one systemic agent, 18.9% with two, 15.1% with three, 22.6% with four, and 3.8% with five. The most commonly used agents were cyclosporine (62.3%), methotrexate (47.2%), azathioprine (39.6%), and dupilumab (35.8%).  

“The switch in therapy could have been a result of inadequate efficacy or cost reasons because in Singapore patients pay out of pocket for AD treatments,” said Dr. Yew.

Additionally, he offered a caveat on the profile of participants: “Perhaps they were more difficult atopic eczema patients, and therefore, the efficacy [of JAK inhibitors] might be a bit different.”
 

Clearer skin, less itch

Patients received one of the three study drugs: baricitinib (66%), abrocitinib (21%), and upadacitinib (13%). The distribution was “affected by reimbursement patterns and availability of the drug,” explained Dr. Yew.

They were assessed at weeks 4 and 12. By study end, the proportion of patients who self-reported an improvement in their condition was 100% for upadacitinib, 90% for abrocitinib, and 69% for baricitinib. 

Scores on the Investigator Global Assessment (IGA) also improved with treatment. Patients in the baricitinib group saw their mean score fall from 4.0 to 3.0 by week 4, then to 2.0 by week 12. With upadacitinib and abrocitinib, “you can see that there is a nice decrease in IGA responses,” said Dr. Yew, referring to the larger improvement in scores experienced by patients on those two treatments. For patients on upadacitinib, IGA decreased from 3.5 to 2 at 4 weeks, then to 0.5 at 12 weeks, while those taking abrocitinib had their scores drop from 4.0 to 2.0 at 4 weeks, then to 1.0 at 12 weeks.

When it came to itch reduction, the abrocitinib group experienced the biggest reduction, with a median reduction of 5.5 points in itch score. Median reduction in itch score was 4 points for the other two groups. “Oral JAK inhibitors appear to have a good effect on itch response,” said Dr. Yew.

However, the researchers observed no significant reduction in percentage of body surface area affected, the last outcome assessed.

The most commonly reported adverse events were increased creatine kinase levels (11.3% of patients), increased LDL cholesterol levels (9.4%), and herpes zoster (9.4%). Those in the abrocitinib reported a higher number of these adverse events, compared with the other two treatment groups. (There were no herpes zoster cases among those taking baricitinib.)

For herpes zoster, Dr. Yew said “the common recommendation” is to give the inactivated shingles vaccine. “But the problem is that, number one, these patients would have probably failed multiple agents so they probably can’t wait for you to vaccinate before you initiate treatment.”

In addition, people in Singapore have to pay out-of-pocket for the two vaccine doses, “which is probably a month’s worth of medication,” he noted. “So we have a lot of resistance from patients.”

Additionally, Dr. Yew noted that contrary to what has previously been reported in the literature, there were few complaints of acne as a side effect in the Singaporean study population.
 

Toward greater representation

Dr. Yew pointed out that the study was limited by a few factors: neither the Eczema Area and Severity Index or Scoring of Atopic Dermatitis index data was used, and the study population was small and not representative of the real world.

Still, the new findings contribute to the overall safety and efficacy profile of JAK inhibitors in AD, which has so far been scarce in non-White populations.

“In Western studies, unfortunately, the representation of the population of skin of color or different ethnicities is underrepresented,” said Yousef Binamer, MD, chair of the dermatology department at King Faisal Specialist Hospital, Riyadh, Saudi Arabia, when approached for an independent comment on the results.

“This is now why researchers are looking into specific groups to study them,” which he pointed out, is crucial because “the immunophenotyping of AD is different for each background.”

The incidence and severity of AD tend to be higher in Asian and Middle Eastern populations, for instance, he noted. “It’s very common in Asia, and not so common in very white skin. I did my training in Canada so I see the difference,” said Dr. Binamer. “Asian people tend to be more itchy and have a tendency to scar on pigmentation.” Whereas White people “usually do not have this issue.” 

“So I think real-world evidence of JAK inhibitors in the other populations is important,” he said. Studies such as the one conducted in Singapore, as well as the recently reported QUARTZ3 study, which examined the use of the JAK inhibitor ivarmacitinib in 256 Chinese patients with AD, are helping to pave the way.

The study was independently supported. Dr. Yew and Dr. Binamer have reported no relevant financial relationships.

The most commonly used agents were cyclosporine (62.3%), methotrexate (47.2%), azathioprine (39.6%), and dupilumab (35.8%).  

“The switch in therapy could have been a result of inadequate efficacy or cost reasons because in Singapore patients pay out of pocket for AD treatments,” said Dr. Yew.

Additionally, he offered a caveat on the profile of participants: “Perhaps they were more difficult atopic eczema patients, and therefore, the efficacy [of JAK inhibitors] might be a bit different.”
 

Clearer skin, less itch

Patients received one of the three study drugs: baricitinib (66%), abrocitinib (21%), and upadacitinib (13%). The distribution was “affected by reimbursement patterns and availability of the drug,” explained Dr. Yew.

They were assessed at weeks 4 and 12. By study end, the proportion of patients who self-reported an improvement in their condition was 100% for upadacitinib, 90% for abrocitinib, and 69% for baricitinib. 

Scores on the Investigator Global Assessment (IGA) also improved with treatment. Patients in the baricitinib group saw their mean score fall from 4.0 to 3.0 by week 4, then to 2.0 by week 12. With upadacitinib and abrocitinib, “you can see that there is a nice decrease in IGA responses,” said Dr. Yew, referring to the larger improvement in scores experienced by patients on those two treatments. For patients on upadacitinib, IGA decreased from 3.5 to 2 at 4 weeks, then to 0.5 at 12 weeks, while those taking abrocitinib had their scores drop from 4.0 to 2.0 at 4 weeks, then to 1.0 at 12 weeks.

When it came to itch reduction, the abrocitinib group experienced the biggest reduction, with a median reduction of 5.5 points in itch score. Median reduction in itch score was 4 points for the other two groups. “Oral JAK inhibitors appear to have a good effect on itch response,” said Dr. Yew.

However, the researchers observed no significant reduction in percentage of body surface area affected, the last outcome assessed.

The most commonly reported adverse events were increased creatine kinase levels (11.3% of patients), increased LDL cholesterol levels (9.4%), and herpes zoster (9.4%). Those in the abrocitinib reported a higher number of these adverse events, compared with the other two treatment groups. (There were no herpes zoster cases among those taking baricitinib.)

For herpes zoster, Dr. Yew said “the common recommendation” is to give the inactivated shingles vaccine. “But the problem is that, number one, these patients would have probably failed multiple agents so they probably can’t wait for you to vaccinate before you initiate treatment.”

In addition, people in Singapore have to pay out-of-pocket for the two vaccine doses, “which is probably a month’s worth of medication,” he noted. “So we have a lot of resistance from patients.”

Additionally, Dr. Yew noted that contrary to what has previously been reported in the literature, there were few complaints of acne as a side effect in the Singaporean study population.
 

Toward greater representation

Dr. Yew pointed out that the study was limited by a few factors: neither the Eczema Area and Severity Index or Scoring of Atopic Dermatitis index data was used, and the study population was small and not representative of the real world.

Still, the new findings contribute to the overall safety and efficacy profile of JAK inhibitors in AD, which has so far been scarce in non-White populations.

“In Western studies, unfortunately, the representation of the population of skin of color or different ethnicities is underrepresented,” said Yousef Binamer, MD, chair of the dermatology department at King Faisal Specialist Hospital, Riyadh, Saudi Arabia, when approached for an independent comment on the results.

“This is now why researchers are looking into specific groups to study them,” which he pointed out, is crucial because “the immunophenotyping of AD is different for each background.”

The incidence and severity of AD tend to be higher in Asian and Middle Eastern populations, for instance, he noted. “It’s very common in Asia, and not so common in very white skin. I did my training in Canada so I see the difference,” said Dr. Binamer. “Asian people tend to be more itchy and have a tendency to scar on pigmentation.” Whereas White people “usually do not have this issue.” 

“So I think real-world evidence of JAK inhibitors in the other populations is important,” he said. Studies such as the one conducted in Singapore, as well as the recently reported QUARTZ3 study, which examined the use of the JAK inhibitor ivarmacitinib in 256 Chinese patients with AD, are helping to pave the way.

The study was independently supported. Dr. Yew and Dr. Binamer have reported no relevant financial relationships.

TOPLINE:

Irradiating a small number of metastatic lesions does not appear to improve progression-free or overall survival in patients receiving immune checkpoint inhibitor monotherapy for advanced cancer.

METHODOLOGY:

• In the phase 2 CHEERS trial, 52 patients with advanced solid tumors were randomized to anti-PD-1/PD-L1 monotherapy and 47 patients to the same treatment plus stereotactic body radiotherapy (3 x 8 Gy) to a maximum of three lesions before the second or third cycle of an immune checkpoint inhibitor.
• Patients had locally advanced or metastatic melanoma, renal cell carcinoma, urothelial carcinoma, non-small cell lung carcinoma, or head and neck squamous cell carcinoma and were treated at five Belgian hospitals.
• Most patients had more than three lesions.
• Seven patients in the experimental group did not complete radiotherapy because of early progression or intercurrent illness.

TAKEAWAY:

• Over a median follow-up of 12.5 months, median progression-free survival was 4.4 months in the radiotherapy group versus 2.8 months in the control group (hazard ratio, 0.95; P = .82).
• Median overall survival was not significantly better with radiotherapy, compared with the control group (14.3 vs. 11 months; HR, 0.82; P = .47), nor was the objective response rate (27% vs. 22%; P = .56).
• However, a post hoc analysis demonstrated a significant association between the number of irradiated lesions and overall survival among patients receiving radiotherapy (HR, 0.31; P = .002).
• The incidence of grade 3 or worse treatment-related adverse events was 18% in both groups.

IN PRACTICE:

Although the study was negative overall, the post hoc analysis coupled with “recent evidence suggests that treating all active disease sites with higher radiation doses ... may be a more promising strategy to optimize systemic disease control,” the authors concluded.
 

SOURCE:

The study was led by Mathieu Spaas, MD, department of radiation oncology, Ghent (Bellgium) University, and published online in JAMA Oncology.

LIMITATIONS:

• There was insufficient power to detect if certain cancers benefited more from add-on radiation because of the small sample size.
• More than half of patients in the control group had already received some form of radiotherapy before study inclusion, which may mean the study underestimated the benefit of radiotherapy.

DISCLOSURES:

The work was funded by Kom Op Tegen Kanker and Varian Medical Systems.

Investigators disclosed numerous industry ties, including Merck, Novartis, and Bristol Myers Squibb.

For understanding the evolution in child neurology over the past 30 years, it would make sense to start with the science, particularly genetics, that have led to treatments and even cures for numerous inherited diseases over that time. When John Bodensteiner, MD, a pillar in the field of child neurology, was asked, he started with something different.

Parent advocacy accelerates advances in rare pediatric diseases

For the progress in many of the rare diseases seen by child neurologists in the last few decades, Dr. Bodensteiner first acknowledged parent support. “The concept was simple initially. For so many of these relatively rare diseases, like the Rett and Sturge-Weber syndromes, parents were learning of them for the first time. The support groups helped parents understand they were not alone. But it then evolved,” recalled Dr. Bodensteiner, who has been a professor of pediatrics and neurology at numerous institutions, most recently the Mayo Clinic in Rochester, Minn.

Many of these support groups first formed, or at least gained momentum, in the 1990s. “As the support groups grew, the members expanded their role to support research, in addition to supporting each other. They ended up volunteering their own data, providing more information about the epidemiology and disease course. They offered tissue samples for experimental studies. They enrolled their children in trials. And they raised funds,” Dr. Bodensteiner explained.

The impact of this advocacy has been enormous, according to Dr. Bodensteiner. As an expert in neuromuscular diseases, he worked directly with several of these groups.

Although the growth in parent advocacy took place in parallel with major advances in genetics that were driving new insights into disease pathophysiology, Dr. Bodensteiner characterized parent advocates as important partners in accelerating the transition of new information to clinical utility. He suggested that there is little doubt about the importance of their role in moving the science forward by drawing attention to rare disorders that had few, if any, treatment options at the time the advocacy groups were formed.

Since the 1990s, the list of childhood neurologic diseases for which there has been meaningful progress is long. Dr. Bodensteiner selected several examples. For Rett syndrome, key molecular mechanisms have now been isolated, providing meaningful targets that show potential for treatment. For spinal muscular atrophy (SMA), therapies have become available, one of which involves gene replacement that appears to provide cure if initiated early in life. For tuberous sclerosis complex (TSC), gene targets are showing strong promise for controlling seizures and other TSC manifestations.

It has also to be acknowledged that much of the ongoing expansion in knowledge taking place across diseases in pediatric neurology would have taken place with or without parent support. Dr. Bodensteiner singled out seizure disorders only as an illustration. “In the various forms of epilepsy, we now understand mechanisms in much greater detail than we did even a decade ago, let alone 30 years ago,” Dr. Bodensteiner said. In the context of the seizure medicines once widely employed on an empirical basis, “we now often have a clearer picture of why one drug works and not another.”
 

Growing pains: Child neurology evolves from a subspecialty to a specialty

Until about 10 years ago, child neurology was a subspecialty, variably placed within the departments of pediatrics or neurology based on institution. The decision to elevate child neurology to its own specialty solved some issues but created others, according to Dr. Bodensteiner.

“The initial problem was there was no immediate funding mechanism of residency slots and training,” Dr. Bodensteiner explained. The issue was particularly acute at smaller centers that had been able to support a subspecialty within another department but struggled with a new autonomous unit.

So far, the training requirements for specializing in child neurology remain largely unchanged. Clinical training requires 2 years of straight pediatrics, 1 year of adult neurology, 1 year of basic neurological science,” and 1 year of child neurology, but Dr. Bodensteiner said it might be time to reconsider. He pointed out that neurologists in general and child neurologists specifically are becoming increasingly focused in one area of expertise, such as epilepsy, neuromuscular diseases, and neurodevelopmental delay.

“It can be argued that a few months spent in a dementia clinic during training might not be the best use of time for a child neurologist working in congenital neurological diseases,” he said.

One consequence of the increasing degree of specialization in neurology overall, not just child neurology, has been the changes in recertification, according to Dr. Bodensteiner. Following a model used in other specialties, recertification in child neurology was initially based on an every-10-year examination. Ultimately, this was recognized as inconsistent with the target of keeping clinicians up to date.

“In general, I think that a lot of people waited for 9.5 years before cramming for an examination that was not necessarily relevant to the area in which they were working,” Dr. Bodensteiner said.

The revised process, carried out on an every-3-year cycle, involves board-guided review of the medical literature in 10 topic areas. Child neurologists can elect an article in any of the topic areas, but to complete their recertification process they must read articles in eight of these areas. Dr. Bodensteiner said that this approach has been more popular and is presumably more useful for staying abreast of developments.
 

Increased specialization necessitates collaboration

The radical increase in specialization in child neurology, like neurology in general, has been a necessary consequence of an avalanche of new information as advances in the field accelerate, but Dr. Bodensteiner cautioned that it is important for those working in these specialized areas to collaborate with others outside of their field of expertise.

“We cannot recognize what we do not know,” Dr. Bodensteiner said. If subspecialization within neurology is critical to stay current with rapid advances in very different diseases, then it also means that clinicians at every level, including within the field of child neurology, need to know when to collaborate or refer to ensure early diagnosis in challenging cases.

“Epileptologists have been trying for years to make it widely known that patients resistant to standard medications deserve referral, but I think this is increasingly true across domains,” Dr. Bodensteiner said. Neurology and child neurology are not alone, but the window of opportunity for effective intervention in children with a progressive disease might be particularly limited.

“The point is that this is more of a risk than it was 20 years ago,” said Dr. Bodensteiner, referring to the growth in new therapies. He cited data suggesting that a causative gene mutation can be identified in about 60% of rare diseases, which is a relatively new phenomenon. Of advances to improve outcomes, faster triage is becoming one of the most important in this increasingly specialized world.

With the growth in knowledge, “there is really no way to be an expert across all diseases in child neurology,” Dr. Bodensteiner said. “As physicians become increasingly insulated in their areas of expertise, I think there needs to be a greater emphasis on communication and collaboration.”

To some degree, this type of specialization has always existed, but Dr. Bodensteiner said the intensification of this trend is among the ways the field has most evolved over the past few decades. In inherited diseases that affect early child development, working together for a prompt diagnosis has assumed a new level of urgency.

Diets containing higher amounts of certain food categories appear to be protective against cardiovascular (CV) disease and premature death, suggests a new study with a broad international scope. Most of the protective food categories are in line with standard dietary guidelines for good health, but one that may be heart-protective is not usually included in such recommendations.

The food categories that were found to be protective include fruit, vegetables, nuts, legumes, and fish but also dairy, “mainly whole-fat,” in an analysis based on the international Prospective Urban and Rural Epidemiological (PURE) study and data from five other international trials that encompassed more than 240,000 people.

A healthy diet scoring system was derived from dietary patterns and clinical events observed in the PURE study and was applied to the populations of the other trials. Higher scores, corresponding to greater consumption of the six food categories, tracked with significantly reduced risks for death, myocardial infarction (MI), and stroke.

Reductions in mortality and CV-disease risk that were linked to the higher scores were especially pronounced in lower-income countries in the study published onlinein the European Heart Journal with lead author Andrew Mente, PhD, Population Health Research Institute, McMaster University, Hamilton, Ont.

The study in part refutes the frequent preference for low-fat or no-fat dairy foods over whole-fat dairy in healthy-diet recommendations. But it is consistent with earlier findings from PURE of reduced mortality risk with increased consumption of dietary fat, including saturated fat.

Whereas healthy-diet recommendations tend to emphasize reduced intake of fat, especially saturated fat, the report notes that “there are almost no national or international strategies and policies to increase a number of protective foods,” such as nuts, fish, and dairy.

“Therefore, while the findings from PURE are largely consistent with the nutrition science and modern dietary recommendations to focus on protective foods, the public’s understanding of healthy eating and relevant global policies have not yet caught up to this science,” it states.

“Guidelines and policy actions need to be updated with this newer evidence,” Dr. Mente said in an interview. “For example, the World Health Organization remains mainly focused on reducing certain nutrients, such as fat, saturated fat, added sugar, and salt,” he said. “These recommendations are echoed by government policy actions and industry, as evident by the continued focus on the usual nutrients in food labels of many countries.”

The current findings, Dr. Mente said, “can be used to ensure that the public’s understanding of healthy eating and relevant global policies are able to catch up to the science.”
 

Healthy diet score

PURE investigators developed their healthy diet score using data from 147,642 people from the general population in 21 countries. The investigators compared self-reported dietary intakes with long-term clinical outcomes.

The scoring system assigned a value of 1 for each of the six health-food categories when individuals’ intake exceeded the entire cohort’s median intake. It assigned a 0 when intake was below the median. The total PURE healthy diet score consisted of the sum of the six values, with higher scores corresponding to a healthier diet. The mean score for cohort was 2.95.

There were 15,707 deaths and 40,764 CV events during a median follow-up of 9.3 years. A score of at least 5 points, compared with 0 or 1 point, was associated with significantly reduced hazard ratios for mortality, MI, and stroke in multivariable analysis:

• Mortality: HR, 0.70 (95% CI, 0.63-0.77; P < .0001).
• Major CV disease: HR, 0.82 (95% CI, 0.75-0.91; P < .0001).
• MI: HR, 0.86 (95% CI, 0.75-0.99; P = .0014).
• Stroke: HR, 0.81 (95% CI, 0.71-0.93; P = .0034).

The healthy diet score’s relationship to clinical outcomes was explored in five other large independent studies, including three prospective trials of patients with CV disease that spanned 50 countries, a case-control study with MI patients in 52 countries, and a case-control study with stroke patients in 33 countries.

In the three prospective trials, higher scores were associated with reduced mortality, CV disease events, and MI:

• Mortality: HR, 0.73 (95% CI, 0.66-0.81).
• Major CV disease: HR, 0.79 (95% CI, 0.72-0.87).
• MI: HR, 0.85 (95% CI, 0.71-0.99).

In the two case-control studies, a higher diet score was associated with reduced odds ratios for first MI and for stroke:

• MI: OR, 0.72 (95% CI, 0.65-0.80).
• Stroke: OR, 0.57 (95% CI, 0.50-0.65).

In an analysis based on the PURE cohort, incorporation of unprocessed red meat or whole grains into the health diet score produced similar results, suggesting that a “modest amount” of meat or whole grains can be part of a healthy diet, the authors contend.

The results were similar in a combined analysis of all the prospective studies. In particular, improvement in diet score by one quintile was associated with significantly reduced risks for the following:

• Mortality: HR, 0.92 (95% CI, 0.90-0.93).
• Major CV disease: HR, 0.94 (95% CI, 0.93-0.95).
• MI: HR, 0.94 (95% CI, 0.92-0.96).
• Stroke: HR, 0.94 (95% CI, 0.89-0.99).
• Death or CV disease: HR, 0.93 (95% CI, 0.92-0.94).

“This strongly indicates that the take-home message for patients is the same as for general populations,” Dr. Mente said. “Eat plenty of fruits, vegetables, nuts, legumes, and a moderate amount of fish and whole-fat dairy to lower risk of CV disease and mortality.”

Dairy foods are not widely consumed in some cultures, he said, “but availability and cost are also factors in determining consumption.” Nonetheless, a high-quality diet can be achieved without including or excluding dairy foods. Context-specific policies and priorities are needed for different populations, “rather than a one-size-fits-all global policy.”

Food labels in many countries mainly focus on “reducing certain nutrients as the end-all, be-all,” Dr. Mente observed. “Our findings can be used as a basis for recommendations regarding what a healthy diet should be globally and then modified for each region based on the specific types of foods that are available and affordable in each region.”

Moreover, he said, “targeted food policies are needed to increase the availability and affordability of healthy foods, especially in lower-income countries where intakes are low.”
 

Common human biology

The current results from PURE “confirm prior observations from mostly Western nations that low intakes of fruits, vegetables, nuts, legumes, and fish are major risk factors for poor health,” observes Dariush Mozaffarian, MD, DrPH, MPH, Tufts University, Boston, in an accompanying editorial. “This suggests that common human biology, not merely confounding, explains these observed diet–disease relationships, strengthening causal inference on the power of nutrition.”

Moreover, “These findings provide further support that dairy foods, including whole-fat dairy, can be part of a healthy diet,” Dr. Mozaffarian writes. “The new results in PURE, in combination with prior reports, call for a re-evaluation of unrelenting guidelines to avoid whole-fat dairy products.”

Such studies “remind us of the continuing and devastating rise in diet-related chronic diseases globally, and of the power of protective foods to help address these burdens,” the editorial continues. “It is time for national nutrition guidelines, private sector innovations, government tax policy and agricultural incentives, food procurement policies, labeling and other regulatory priorities, and food-based health care interventions to catch up to the science.”
 

Not automatically superior

“I do not believe guidelines should be changed based on this single study,” contends Howard D. Sesso, ScD, MPH, associate director of the division of preventive medicine at Brigham and Women’s Hospital, Boston, who isn’t part of PURE. “But I welcome the scientific dialog that should come out of any study that challenges what we think we know,” he told this news organization.

“Many other dietary patterns have been identified over the years that also do a great job in predicting disease risk in observational studies,” observed Dr. Sesso. “Is PURE that much better? Maybe, maybe not. But not enough to dismiss other dietary patterns that are already the basis of dietary recommendations in the U.S., Europe, and worldwide.”

The PURE healthy diet score, he said, “appears to work well within the confines of their large pooling of studies around the world, but that doesn’t automatically make it superior to other dietary patterns.” The score “was only modestly, but not greatly, better than existing dietary patterns evaluated.”

Randomized controlled trials are needed, Dr. Sesso said, to “delve into more specific dietary components,” including unprocessed red meat, whole grains, and high-fat dairy foods. And, he said, more observational studies are needed to examine the score’s association with other cardiometabolic outcomes.

The PURE study is funded by the Population Health Research Institute, the Hamilton Health Sciences Research Institute, the Canadian Institutes of Health Research, the Heart and Stroke Foundation of Ontario; with support from Canadian Institutes of Health Research’s Strategy for Patient Oriented Research through the Ontario SPOR Support Unit, as well as the Ontario Ministry of Health and Long-Term Care; and through unrestricted grants from several pharmaceutical companies, with major contributions from AstraZeneca, Sanofi-Aventis, Boehringer Ingelheim, Servier, and GlaxoSmithKline. Additional contributions are from Novartis and King Pharma. Dr. Mente, Dr. Mozaffarian, and Dr. Sesso have disclosed no relevant financial relationships.

Diets containing higher amounts of certain food categories appear to be protective against cardiovascular (CV) disease and premature death, suggests a new study with a broad international scope. Most of the protective food categories are in line with standard dietary guidelines for good health, but one that may be heart-protective is not usually included in such recommendations.

The food categories that were found to be protective include fruit, vegetables, nuts, legumes, and fish but also dairy, “mainly whole-fat,” in an analysis based on the international Prospective Urban and Rural Epidemiological (PURE) study and data from five other international trials that encompassed more than 240,000 people.

A healthy diet scoring system was derived from dietary patterns and clinical events observed in the PURE study and was applied to the populations of the other trials.

The Food and Drug Administration has approved a labeling update for the injectable LDL cholesterol–lowering agent inclisiran (Leqvio) that expands its indications to include primary prevention for patients with elevated LDL cholesterol, Novartis has announced.

The first-in-class small interfering RNA (siRNA) agent was approved in 2021 as an adjunct to statins for patients with clinical cardiovascular disease or heterozygous familial hypercholesterolemia. The indications now include patients taking statins for primary dyslipidemia who have high-risk comorbidities such as diabetes but who do not have a history of cardiovascular events, the company said.

Inclisiran, with a mechanism of action unique among drugs for dyslipidemia, works by “silencing” RNA involved in the synthesis of proprotein convertase subtilisin/kexin type 9. The protein helps regulate the number of LDL cholesterol cell-surface receptors.

Novartis said it has “global rights to develop, manufacture and commercialize Leqvio under a license and collaboration agreement with Alnylam Pharmaceuticals.”

SINGAPORE – When injected subcutaneously, the interleukin-36 receptor antagonist spesolimab significantly reduced the risk for generalized pustular psoriasis (GPP) flares, according to results of a study presented in a late-breaker session at the World Congress of Dermatology,

In the phase 2b study, patients who received the high-dose regimen (a 600-mg subcutaneous loading dose, then 300-mg SC every 4 weeks) of spesolimab experienced 84% fewer GPP fares over 48 weeks, compared with those on placebo, reported Bruce Strober, MD, PhD, Central Connecticut Dermatology, Cromwell, and clinical professor of dermatology, Yale University, New Haven, Conn. “Additionally, no flares occurred after week 4, and this, in turn, translated into improved patient outcomes.”

GPP is a rare, chronic, systemic neutrophilic skin disease. The resulting flares, characterized by painful pustules all over the body, can lead to sepsis, shock, and other life-threatening complications. “People who have it are considerably burdened by it, so targeted therapy of this disease is incredibly important because it leads to lessened morbidity and, importantly, mortality for these patients,” Dr. Strober said.

“It’s important not only to treat the flares but also to prevent them,” he noted.

The intravenous formulation of spesolimab (Spevigo) was approved for the treatment of GPP flares in adults by the Food and Drug Administration in September 2022. It is now authorized in nearly 40 countries, including Japan, China, and the European Union.

The phase 2 Effisayil 2 study presented at the meeting evaluated the subcutaneous formulation of spesolimab. Data on subcutaneous spesolimab has been submitted to the FDA, and has received breakthrough therapy designation, according to the manufacturer, Boehringer Ingelheim.

Flare prevention

In the study, 123 patients with GPP were randomly assigned 1:1:1:1 to one of four groups: high-dose spesolimab, medium-dose (600-mg SC loading dose, then 300-mg SC every 12 weeks), low-dose (300-mg SC loading dose, then 150-mg SC every 12 weeks), or placebo. In the event of a flare during the randomized treatment period, a patient was administered a single, 900-mg intravenous dose of spesolimab.

Nearly two-thirds of the participants were female and nearly two-thirds were Asian, with a mean age of about 39-43 years.

The mean numbers of GPP flares experienced annually by those in the low-, medium-, and high-dose spesolimab groups were 2.7, 1.9, and 2.4, respectively (2.4% in the placebo group). Fewer than a third had concurrent plaque psoriasis at baseline. Most (48.4%-63.3%) did not have an IL-36RN mutation.

Additionally, the Generalized Pustular Psoriasis Physician Global Assessment total score was 1 in 74.2%-93.5% of participants, and 0 in the remainder.

The primary study endpoint was the time to GPP flare by week 48. The risk of developing a flare among those on high-dose spesolimab was 84% lower, compared with that of those on placebo (hazard ratio, 0.16; 95% confidence interval, 0.05-0.54; P = .0005). No patients on the high dose had a flare after the 4th week of the study.

Similarly, for the secondary endpoint (occurrence of at least one GPP flare by week 48). Dr. Strober and his colleagues reported that high-dose spesolimab was superior to placebo with a risk difference of -39% (95% CI, –0.62 to –0.16; P = .0013). By contrast, the risk differences for the medium- and low-dose spesolimab arms were –0.23 (95% CI, –0.46 to 0.01) and -0.31 (95% CI, –0.54 to –0.08), respectively.

The safety profile of subcutaneous spesolimab across all three doses was similar to that of placebo, and there was no dose-dependent trend. Reported adverse events (AEs) were mild. There were five (5.4%) AEs leading to discontinuation of the drug in the medium- and high-dose groups, but none in the low-dose group. Overall, there were nine (9.7%) serious AEs reported in the spesolimab groups, and three (10%) in the high-dose group; no deaths occurred on any dose.

Participants most often reported injection-site erythema, reported in 13 (14%) of the patients on spesolimab versus 1 (3.3%) of those on placebo.

“Overall, the study demonstrates that subcutaneous spesolimab is effective at controlling GPP flares, especially at a high dose relative to placebo, and supports subcutaneous spesolimab for the therapy for GPP flare prevention,” Dr. Strober said at the meeting.
 

Targeting the IL-36 pathway

In a comment, Todd Schlesinger, MD, Clinical Research Center of the Carolinas, Charleston, S.C., who moderated the session, said: “It’s very exciting to be able to have a subcutaneous version of the medication.”

“I think the IL-36 is a great pathway,” he said, referring to the signaling pathway within the immune system that is central to the pathogenesis of GPP and several other autoinflammatory diseases.

However, Dr. Schlesinger said that he would have liked to have seen data on how many patients ended up treated with intravenous spesolimab.

He added that he would like future studies of subcutaneous spesolimab to examine the effect in different populations that vary by parameters such as weight, race, and disease severity. “Just seeing how somebody who’s flaring five times a year and you give them this medication and they’re now flaring once a year – that’s interesting data that we might like to know in the future.”

Other than for preventing GPP flares, spesolimab is being studied for treating other IL-36–mediated skin diseases, such as palmoplantar pustulosis.

The study was funded by Boehringer Ingelheim; both Dr. Strober and Dr. Schlesinger do research and consulting for BI, and receive funding from multiple other pharmaceutical companies.

SINGAPORE – When injected subcutaneously, the interleukin-36 receptor antagonist spesolimab significantly reduced the risk for generalized pustular psoriasis (GPP) flares, according to results of a study presented in a late-breaker session at the World Congress of Dermatology,

In the phase 2b study, patients who received the high-dose regimen (a 600-mg subcutaneous loading dose, then 300-mg SC every 4 weeks) of spesolimab experienced 84% fewer GPP fares over 48 weeks, compared with those on placebo, reported Bruce Strober, MD, PhD, Central Connecticut Dermatology, Cromwell, and clinical professor of dermatology, Yale University, New Haven, Conn. “Additionally, no flares occurred after week 4, and this, in turn, translated into improved patient outcomes.”

GPP is a rare, chronic, systemic neutrophilic skin disease. The resulting flares, characterized by painful pustules all over the body, can lead to sepsis, shock, and other life-threatening complications. “People who have it are considerably burdened by it, so targeted therapy of this disease is incredibly important because it leads to lessened morbidity and, importantly, mortality for these patients,” Dr. Strober said.

“It’s important not only to treat the flares but also to prevent them,” he noted.

The intravenous formulation of spesolimab (Spevigo) was approved for the treatment of GPP flares in adults by the Food and Drug Administration in September 2022. It is now authorized in nearly 40 countries, including Japan, China, and the European Union.

The phase 2 Effisayil 2 study presented at the meeting evaluated the subcutaneous formulation of spesolimab. Data on subcutaneous spesolimab has been submitted to the FDA, and has received breakthrough therapy designation, according to the manufacturer, Boehringer Ingelheim.

Flare prevention

In the study, 123 patients with GPP were randomly assigned 1:1:1:1 to one of four groups: high-dose spesolimab, medium-dose (600-mg SC loading dose, then 300-mg SC every 12 weeks), low-dose (300-mg SC loading dose, then 150-mg SC every 12 weeks), or placebo. In the event of a flare during the randomized treatment period, a patient was administered a single, 900-mg intravenous dose of spesolimab.

Nearly two-thirds of the participants were female and nearly two-thirds were Asian, with a mean age of about 39-43 years.

Hi. I’m Art Caplan, PhD. I’m director of the division of medical ethics at the New York University Grossman School of Medicine.

Every once in a while at my school, I get referrals about interesting or difficult clinical cases where doctors would like some input or advice that they can consider in managing a patient. Sometimes those requests come from other hospitals to me. I’ve been doing that kind of ethics consulting, both as a member of various ethics committees and sometimes individually, when, for various reasons, doctors don’t want to go to the Ethics Committee as a first stop.

There was a very interesting case recently involving a young woman I’m going to call Tinslee. She was 17 years old and she suffered, sadly, from recurrent metastatic osteogenic sarcoma. She had bone cancer. It had first been diagnosed at the age of 9. She had received chemotherapy and been under that treatment for a while.

If osteosarcoma is treated before it spreads outside the area where it began, the 5-year survival rate for people like her is about 75%. If the cancer spreads outside of the bones and gets into surrounding tissues, organs, or – worse – into the lymph nodes and starts traveling around, the 5-year survival rate drops to about 60%. The two approaches are chemotherapy and amputation. That’s what we have to offer patients like Tinslee.

Initially, her chemotherapy worked. She went to school and enjoyed sports. She was a real fan of softball and tried to manage the team and be involved. At the time I learned about her, she was planning to go to college. Her love of softball remained, but given the recurrence of the cancer, she had no chance to pursue her athletic interests, not only as a player, but also as a manager or even as a coach for younger players. That was all off the table.

She’d been very compliant up until this time with her chemotherapy. When the recommendation came in that she undergo nonstandard chemotherapy because of the reoccurrence, with experimental drugs using an experimental protocol, she said to her family and the doctors that she didn’t want to do it. She would rather die. She couldn’t take any more chemotherapy and she certainly didn’t want to do it if it was experimental, with the outcomes of this intervention being uncertain.

Her dad said, “She can’t decide. She’s a minor. She’s only 17. I want you to do it – administer this novel form of chemotherapy and try to save her.” Her mother said, “Her input matters. I want to listen to her.” Her mom wasn’t as adamant about doing it or not, but she really felt that Tinslee should be heard loudly because she felt she was mature enough or old enough, even though a minor, to really have a position about what it is to undergo chemotherapy.

Time matters in trying to control the spread, and the doctors were pushing for experimental intervention. I should add, by the way, that although it didn’t really drive the decision about whether to do it or not do it, experimental care like this is not covered by most insurance, and it wasn’t covered by their insurance, so they were facing a big bill if the experimental intervention was administered.

There was some money in a grant to cover some of it, but they were going to face some big financial costs. It never came up in my discussions with the doctors about what to do. I’m not sure whether it ever came up with the family’s discussion with the doctors about what to do, or even whether Tinslee was worrying and didn’t want her family to face a financial burden.

I suggested that we bring the family in. We did some counseling. We had a social worker and we brought in a pastor because these people were fairly religious. We talked about all scenarios, including accepting death, knowing that this disease was not likely to go into remission with the experimental effort; maybe it would, but the doctors were not optimistic.

We tried to talk about how much we should listen to what this young woman wanted. We knew there was the possibility of going to court and having a judge decide this, but in my experience, I do not like going to judges and courts because I know what they’re going to say. They almost always say “administer the intervention.” They don’t want to be in a position of saying don’t do something. They’re a little less willing to do that if something is experimental, but generally speaking, if you’re headed to court, it’s because you’ve decided that you want this to happen.

I felt, in all honesty, that this young woman should have some real respect of her position because the treatment was experimental. She is approaching the age of competency and consent, and she’s been through many interventions. She knows what’s involved. I think you really have to listen hard to what she’s saying.

By the way, after this case, I looked and there have been some surveys of residents in pediatrics. A large number of them said that they hadn’t received any training about what to do when mature minors refuse experimental treatments. The study I saw said that 30% had not undergone any training about this, so we certainly want to introduce that into the appropriate areas of medicine and talk about this with residents and fellows.

Long story short, we had the family meeting, we had another meeting with dad and mom and Tinslee, and the dad began to come around and he began to listen hard. Tinslee said what she wanted was to go to her prom. She wanted to get to her sister’s junior high school softball championship game. If you will, setting some smaller goals that seemed to make her very, very happy began to satisfy mom and dad and they could accept her refusal.

Ultimately, an agreement was reached that she would not undergo the experimental intervention. We agreed on a course of palliative care, recommended that as what the doctors follow, and they decided to do so. Sadly, Tinslee died. She died at home. She did make it to her prom.

I think the outcome, while difficult, sad, tragic, and a close call, was correct. Mature minors who have been through a rough life of interventions and know the price to pay – and for those who have recurrent disease and now face only experimental options – if they say no, that’s something we really have to listen to very hard.

Long story short, we had the family meeting, we had another meeting with dad and mom and Tinslee, and the dad began to come around and he began to listen hard. Tinslee said what she wanted was to go to her prom. She wanted to get to her sister’s junior high school softball championship game. If you will, setting some smaller goals that seemed to make her very, very happy began to satisfy mom and dad and they could accept her refusal.

Ultimately, an agreement was reached that she would not undergo the experimental intervention. We agreed on a course of palliative care, recommended that as what the doctors follow, and they decided to do so. Sadly, Tinslee died. She died at home. She did make it to her prom.

I think the outcome, while difficult, sad, tragic, and a close call, was correct. Mature minors who have been through a rough life of interventions and know the price to pay – and for those who have recurrent disease and now face only experimental options – if they say no, that’s something we really have to listen to very hard.

Scientists have developed a biodegradable implant that helps chemotherapy drugs penetrate the blood-brain barrier in mice and deliver a direct hit on brain tumors.

It’s the latest advance in a rapidly growing field using ultrasound – high-frequency sound waves undetectable to humans – to fight cancer and other diseases.

The problem addressed by the researchers is the blood-brain barrier, a nearly impenetrable blood vessel lining that keeps harmful molecules from passing into the brain from the blood. But this lining can also block chemo drugs from reaching cancer cells.

So the scientists implanted 1-cm² devices into the skulls of mice, directly behind the tumor site. The implants generate ultrasound waves, loosening the barrier and allowing the drugs to reach the tumor. The sound waves leave healthy tissue undamaged.

“You inject the drug into the body and turn on the ultrasound at the same time. You’re going to hit precisely at the tumor area every single time you use it,” said lead study author Thanh Nguyen, PhD, an associate professor of mechanical engineering at the University of Connecticut, Storrs.

The drug used in the study was paclitaxel, which normally struggles to get through the blood-brain barrier. The tumors shrank, and the mice doubled their lifetime, compared with untreated mice. The mice showed no bad health effects 6 months later. 
 

Breaking through the blood-brain barrier 

The biodegradable implant is made of glycine, an amino acid that’s also strongly piezoelectric, meaning it vibrates when subjected to an electrical current. To make it, researchers cultivated glycine crystals, shattered them into pieces, and finally used a process called electrospinning, which applies a high electrical voltage to the nanocrystals. 

Voltage flows to the implant via an external device. The resulting ultrasound causes the tightly adhered cells of the blood-brain barrier to vibrate, stretching them out and creating space for pores to form. 

“That allows in very tiny particles, including chemo drugs,” said Dr. Nguyen. 

His earlier biodegradable implant broke apart from the force, but the new glycine implant is more flexible, stable, and highly piezoelectric. It could be implanted after a patient has surgery to remove a brain tumor, to continue treating residual cancer cells. The implant dissolves harmlessly in the body over time, and doctors can control its lifespan. 
 

A new wave of uses for ultrasound 

Dr. Nguyen’s study builds on similar efforts, including a recent clinical trial of a nonbiodegradable implant for treating brain tumors. Ultrasound can focus energy on precise targets in the body.

It’s like “using a magnifying glass to focus multiple beams of light on a point and burn a hole in a leaf,” said Neal Kassell, MD, founder and chairman of the Focused Ultrasound Foundation. This approach spares adjacent normal tissue.  

Doctors now understand more than 30 ways that ultrasound interacts with tissue – from destroying abnormal tissue to delivering drugs more effectively to stimulating an immune response. A decade ago, only five such interactions were known.

This opens the door for treating “a wide spectrum of medical disorders,” from neurodegenerative diseases like Alzheimer’s and Parkinson’s to difficult-to-treat cancers of the prostate and pancreas, and even addiction, said Dr. Kassell. 

Dr. Kassell envisions using focused ultrasound to treat brain tumors as an alternative (or complement) to surgery, chemotherapy, immunotherapy, or radiation therapy. In the meantime, implants have helped show “the effectiveness of opening the blood-brain barrier.”

Dr. Nguyen’s team plans on testing the safety and efficacy of their implant in pigs next. Eventually, Dr. Nguyen hopes to develop a patch with an array of implants to target different areas of the brain.
