MILAN – Targeted synthetic and biologic therapies are recommended as disease-modifying agents for key fibrotic manifestations of systemic sclerosis for the first time in the 2023 update of European Alliance of Associations for Rheumatology recommendations for the treatment of systemic sclerosis.

Reflecting important advances over the past 8 years, mostly relating to the use of new treatments being made available to patients, the recommendations provide an update on the 2017 recommendations, which relied on evidence published through 2014. Of note, these include the use of immunosuppressive agents, for example, the monoclonal antibody rituximab (Rituxan) for skin and lung fibrosis.

“For the first time, synthetic and targeted treatments are recommended for the treatment of systemic sclerosis–interstitial lung disease, including mycophenolate mofetil [Cellcept], nintedanib [Ofev], rituximab, and tocilizumab [Actemra]. None of these were present in 2017. Mycophenolate mofetil is also recommended for the treatment of skin fibrosis, and this was not present in 2017,” Francesco Del Galdo, MD, rheumatology consultant at Leeds Teaching Hospital NHS Trust, Leeds, England, and member of the 2023 recommendations task force, said in an interview. He gave an overview of the preliminary recommendations at the annual European Congress of Rheumatology.

“Phosphodiesterase-5 [PDE-5] inhibitors and endothelin receptor antagonist [ERA] monotherapy are also recommended for up-front combination use for digital ulcers and pulmonary hypertension, and this is new for 2023 and was not present in the 2017 recommendations,” Dr. Del Galdo added.

The new recommendations also note that iloprost is categorized as having grade A evidence for use in Raynaud’s phenomenon and digital ulcers, while it has grade B evidence for pulmonary hypertension.

“We are not allowed to share the final table [of recommendations] today because the wording has only very recently been agreed” upon, Dr. Del Galdo said, but he provided a summary representation and reflected on some changes, noting that the task force is aiming to publish the 2023 recommendations by the end of the year.

Consideration and discussion of both established and new evidence highlighted a need for more evidence on the use of immunosuppressive agents in vascular manifestations of systemic sclerosis, as well as for gastrointestinal and musculoskeletal ones.

In this update to the 2017 recommendations, high-grade evidence was identified for use of immunosuppressants in skin and lung fibrosis. Grade A evidence has been accepted for the use of rituximab in skin fibrosis; for interstitial lung disease, rituximab, cyclophosphamide, and nintedanib also have grade A evidence, which is a change from the 2017 recommendations.

A total of 20 updated recommendations were agreed on, an increase from 16 in 2017. These were grouped into eight disease domains: Raynaud’s phenomenon, digital ulcers, pulmonary arterial hypertension, skin fibrosis, interstitial lung disease, musculoskeletal and gastrointestinal manifestations, and renal crisis. Interventions were then graded A-D based on the evidence reviewed.

“This approach allowed us to see clearly that there were patterns of similar recommendations in different organ manifestations, reflecting an understanding of common pathogenic pathways,” said Dr. Del Galdo.

He also noted that the development of the recommendations highlighted certain gaps in research that limit treatment options. “By grouping the recommendations in blocks – for example, skin fibrosis or vascular [manifestations] – we show that immunosuppressive treatments have only been studied in skin and lung, while vascular manifestations have very little evidence for immunosuppression. They might be effective but there’s no evidence yet [hence no recommendation in vascular manifestations].”

“Also, there’s no grade A evidence at all for musculoskeletal and gastrointestinal manifestations, and this should help to define the research agenda going forward,” Dr. Del Galdo said.

The 2023 recommendations task force comprised 28 members from 14 countries, including 18 rheumatologists, 1 EULAR methodologist, 1 health professional representative, 5 rheumatology fellows, 1 librarian, and 2 patient representatives. They used a consensual approach incorporating the views of 101 European Scleroderma Trials and Research group (EUSTAR) centers, sourced via a survey in which questions were advanced to an extensive systematic review if there was 70% or greater agreement.

Eventually, 31 questions on interventions were chosen, and the task force reviewed 12,500 abstracts (up to December 2022) related to interventions and outcomes that were either included in the 2017 recommendations or were totally new.

Dr. Del Galdo said that the three vascular manifestations of scleroderma – Raynaud’s, pulmonary arterial hypertension, and digital ulcers – were treated with the same drugs, all with a similar grade of evidence. “This suggests two things – firstly there’s a vascular disease continuum in the disease, and secondly, we’ve borrowed these drugs from vascular community, but we have not yet tested synthetic and biologic targeted treatments in these manifestations, and we should.

“Treating one manifestation may benefit the other, and this is important time wise because pulmonary hypertension usually comes around 10 years after the first phenomena so by treating digital ulcers and Raynaud’s phenomena, we may prevent pulmonary hypertension, but a study is needed,” added Dr. Del Galdo, who is also president of EUSTAR.

Finally, he pointed out that research remains particularly open for nonpharmacologic treatments for digital ulcers and severe gastrointestinal involvement. “Patients can now ask for studies into this because of the current lack of evidence.”

Moderator Ariane Herrick, PhD, professor of rheumatology at the University of Manchester (England), shared her thoughts on the guidelines. “These recommendations have been long awaited by the scleroderma community because there has been some exciting progress in recent years, and the new recommendations reflect these new developments.”

Commenting on the paucity of evidence in some areas, she added that “there do remain some huge areas of unmet need that are difficult to address, and these are musculoskeletal, gastrointestinal, and calcinosis, for which there have been no trials at all.”

Dr. Del Galdo declared disclosures relating to AstraZeneca, Janssen, Boehringer Ingelheim, Capella, Chemomab, GlaxoSmithKline, and Mitsubishi-Tanabe. Dr. Herrick disclosed serving as a consultant for Boehringer Ingelheim and Janssen.

MILAN – About 80% of patients with gout who took the investigational selective uric acid transporter 1 (URAT1) inhibitor AR882 over 3 months reduced their serum uric acid levels to below recommended thresholds (below 5 or 4 mg/dL) for better flare and tophi reduction in a phase 2b study.

The drug was well tolerated, and patients with comorbidities did not require any adjustments in disease management.

At 75 mg, the highest tested dose of AR882, 73% of patients had serum uric acid levels < 5 mg/dL and 55% had < 4 mg/dL by week 12 of therapy in the intent-to-treat population, whereas in the per-protocol analysis, 82% had serum uric acid levels < 5 mg/dL and 63% < 4 mg/dL.

“These efficacy results are not typically what you see with a once-daily oral medication, so it is really exciting,” Robert Keenan, MD, chief medical officer of Arthrosi Therapeutics, San Diego, said in presenting the results at the annual European Congress of Rheumatology.

“Regardless of whether you’re treating subclinical, hidden crystal deposition, versus clinically visible tophi, versus chronic, debilitating gout, we believe that AR882 has the potential to treat the entire gout spectrum with a once-daily monotherapy,” Dr. Keenan asserted.

“Currently, most gout patients around the world do not have a safe, effective, and easy to use alternative to allopurinol or febuxostat, which decrease the production of uric acid,” he said. “AR882 is a URAT1 inhibitor that goes to the root of the problem in over 90% of gout patients, helping the kidneys eliminate uric acid to levels similar to all those without hyperuricemia and gout.”

Abhishek Abhishek, MD, professor of rheumatology at the University of Nottingham (England), welcomed the study. “It’s a promising study and the reduction in uric acid was substantial. It was a small study and a larger phase 3 study is needed, but it does offer real hope for patients with gout as a third treatment option because we only have allopurinol and febuxostat, so if it is shown efficacious and safe and gets approved, then it’ll help more patients with gout.”

Anne-Kathrin Tausche, MD, a rheumatologist from University Clinic Dresden (Germany), said: “These results are really impressive. We’ve lost lesinurad now because Grünenthal no longer produces it, so this might be a good alternative for patients with severe gout.

“It is favorable with [few] side effects. With allopurinol, we have to titrate it in patients with poor renal function, but it doesn’t seem to be the case with this drug. I really hope they start phase 3 soon,” she added.
 

Phase 2 study, but promising results

Results of the global phase 2b, randomized, double-blind trial compared the safety, tolerability, and efficacy of AR882 against placebo in patients with gout.

A total of 140 patients with gout, aged 18-75 years with an estimated glomerular filtration rate (eGFR) > 30 mL/min, were recruited across the United States, Australia, and Taiwan. Patients received either once-daily AR882 50 mg (n = 46) for 12 weeks, AR882 50 mg for 2 weeks and then AR882 75 mg (n = 47) for 10 weeks, or matching placebo for 12 weeks (n = 47). Flare prophylaxis with daily colchicine started 10 days prior to the first dose and continued throughout the study.

“Patient characteristics were typical for gout trials except for having a very diverse population,” he said. The trial included 57.9% White, 27.9% Asian, and 15% Black patients. They had a mean age of 55 years, body mass index 31-32 kg/m². There was a range of comorbidities including hypertension, hyperlipidemia, diabetes, and cardiovascular disease, evenly distributed across placebo and AR882 treatment groups.

The efficacy endpoints were the proportion of patients who reached serum uric acid below 6, 5, 4, and 3 mg/dL, at 6 weeks of therapy, while safety was also monitored throughout the study. Reductions in serum uric acid at weeks 2, 4, 6, 12 were exploratory endpoints.

The primary endpoint of the percentage of patients below < 6 mg/dL at 6 weeks in the intent-to-treat population was met by 66% with AR882 at the lower dose (50 mg) and 84% at the higher dose (75 mg).

With the 50-mg dose, serum uric acid was reduced at week 6 to < 5mg/dL by 41%, < 4mg/dL by 12%, and < 3mg/dL by 2%, whereas these percentages were 68%, 52%, and 23%, respectively, with the 75-mg dose.

Exploratory endpoints showed that by week 12, serum uric acid levels dropped from baseline 8.6 mg/dL to about 5.0 mg/dL with AR882 50 mg and from baseline 8.6 mg/dL to about 3.5 mg/dL with AR882 75 mg. Also at week 12, 55% and 23% reached serum uric acid levels of < 4mg/dL and < 3mg/dL in the intent-to-treat population. No change was observed in the placebo group.

All adverse events were mild to moderate, with the most prevalent being gout flares. There was little difference between doses. There were no clinically significant changes in a total of 778 post-dose measurements of alanine transaminase (ALT) and aspartate transaminase (AST) and 723 post-dose triplicated electrocardiogram (ECG) measurements.

With the 50-mg dose, serum uric acid was reduced at week 6 to < 5mg/dL by 41%, < 4mg/dL by 12%, and < 3mg/dL by 2%, whereas these percentages were 68%, 52%, and 23%, respectively, with the 75-mg dose.

Exploratory endpoints showed that by week 12, serum uric acid levels dropped from baseline 8.6 mg/dL to about 5.0 mg/dL with AR882 50 mg and from baseline 8.6 mg/dL to about 3.5 mg/dL with AR882 75 mg. Also at week 12, 55% and 23% reached serum uric acid levels of < 4mg/dL and < 3mg/dL in the intent-to-treat population. No change was observed in the placebo group.

All adverse events were mild to moderate, with the most prevalent being gout flares. There was little difference between doses. There were no clinically significant changes in a total of 778 post-dose measurements of alanine transaminase (ALT) and aspartate transaminase (AST) and 723 post-dose triplicated electrocardiogram (ECG) measurements.

MILAN – Results of a phase 3 trial with the investigational drug telitacicept show that patients with systemic lupus erythematosus have a significantly greater rate of response to SLE response criteria, compared with placebo, while results from a phase 2 trial of the drug in patients with primary Sjögren’s syndrome (pSS) also show significant improvements versus placebo.

“With only a limited number of treatments available for patients with lupus, this additional option is certainly an advance and the trial shows a strong efficacy result,” said Ronald van Vollenhoven, MD, PhD, who was not an investigator for either trial but presented the results for both at the annual European Congress of Rheumatology. He is professor of clinical immunology and rheumatology at Amsterdam University Medical Center and VU University Medical Center, also in Amsterdam.

Telitacicept is a recombinant fusion protein that targets B-lymphocyte stimulator and a proliferating-inducing ligand. It is currently undergoing testing in another phase 3 trial (REMESLE-1) at sites in the United States, Europe, and Asia. The current SLE results relate to the phase 3 study conducted in China, Dr. van Vollenhoven clarified.
 

SLE trial

The double-blind, placebo-controlled trial included 335 patients with SLE who had an average age of 35 years, a body mass index of 22-23 kg/m², and a mean SELENA-SLEDAI (Safety of Estrogens in Systemic Lupus Erythematosus National Assessment–Systemic Lupus Erythematosus Disease Activity Index) score of at least 11.5, indicating high disease activity. Most patients were on glucocorticoids and immunosuppressants.

Patients were randomized 1:1 to weekly subcutaneous injections of telitacicept (160 mg; n = 167) or placebo (n = 168) in combination with standard therapy for 52 weeks. The primary endpoint was the SLE Responder Index-4 (SRI4) response rate at week 52, while key secondary endpoints included SELENA-SLEDAI, physician global assessment, and levels of immunologic biomarkers including C3, C4, IgM, IgG, IgA, and CD19+ B cells. Safety was also assessed.

At week 52, Dr. van Vollenhoven reported that significantly more patients taking telitacicept achieved a SRI4 response, compared with placebo, at 67.1% versus 32.7%, respectively (P < .001). “The difference was seen at 4-8 weeks and stabilized at around 20 weeks,” he said.

Time to first SLE flare was also reduced in patients on the trial drug at a median of 198 days (95% confidence interval, 169-254 days), compared with placebo at 115 days (95% CI, 92-140 days).

“The secondary outcomes also supported efficacy in these patients,” Dr. van Vollenhoven added, noting that there was a rapid and sustained increase of C3 and C4, the latter being significantly greater than placebo, and reduction of IgM, IgG, IgA, and CD19+ B cells observed following telitacicept treatment.

A significantly higher proportion of patients in the telitacicept group showed improvement in SELENA-SLEDAI at week 52, defined as a 4-point or greater reduction, compared with placebo (70.1% vs. 40.5%).

Telitacicept did not increase the risk of infections. Treatment-emergent adverse events occurred in 84.5% with telitacicept versus 91.6% with placebo, with infections (mostly upper respiratory) seen in 65.3% and 60.1%, respectively.
 

Sjögren’s trial

The second trial was a phase 2, randomized, placebo-controlled, 24-week study in 42 patients with pSS. Patients (18-65 years) received telitacicept at 160 mg or 240 mg subcutaneously once a week, or placebo, for a total of 24 doses. Patients had a EULAR Sjögren’s Syndrome Disease Activity Index (ESSDAI) score of 5 points or more, and were anti-SSA antibody positive.

“Compared with placebo, telitacicept treatment resulted in significant improvement in ESSDAI and MFI-20 [20-item Multidimensional Fatigue Inventory],” Dr. van Vollenhoven reported, adding that, “there was a trend for improvement in salivary gland function and lacrimal gland function relative to placebo, as well as a favorable safety profile.”

ESSDAI change from baseline was 0.5, –3.8, and –2.3 in placebo, 160-mg, and 240-mg telitacicept doses, respectively. MFI-20 change from baseline was 7.0, –4.0, and –5.1, respectively. Dr. Van Vollenhoven said the difference between the doses was not statistically significant.

“If these results are confirmed, it could be the first time a biologic is proven efficacious in this disease,” Dr. Van Vollenhoven said in an interview. “It’s encouraging to know that a new treatment is showing promise in this phase 2 trial. A phase 3 trial is warranted.”
 

Studies yield promising but confusing results

In an interview, Roy Fleischmann, MD, who was not involved with either study, wondered whether the results of the SLE study could be race specific given the magnitude of response to the drug and that the trial was conducted only in China, and whether the positive results of the small Sjögren’s study will pan out in a larger trial.

“The SLE study was very interesting, but the problem is that it’s a Chinese drug in Chinese patients with Chinese doctors, so they are very dramatic results,” he said, questioning whether “these results are race specific,” and that “we will find out when they do the multinational study, but we haven’t seen this type of separation before [in response]. It’s interesting.

“The Sjögren’s was a positive study, but it was confusing because the low dose seemed to be better than the higher dose, and there were very few patients,” said Dr. Fleischmann, clinical professor of medicine at the University of Texas Southwestern Medical Center and codirector of the Metroplex Clinical Research Center, both in Dallas. The left and right eyes gave different results, which was strange, and the salivary gland test was the same [mixed results], so what can we conclude? All in all, it was a small study with a suggestion of efficacy, but we have to do the phase 3 and see what it shows.”

Both trials were sponsored by RemeGen. Dr. van Vollenhoven reported serving as a paid adviser to AbbVie, AstraZeneca, Biogen, Bristol-Myers Squibb, Galapagos, GlaxoSmithKline, Janssen, Pfizer, RemeGen, and UCB. He has received research funding from Bristol-Myers Squibb and UCB and educational support from AstraZeneca, Galapagos, Merck Sharp & Dohme, Novartis, Pfizer, Roche, Sanofi, and UCB. Dr. Fleischmann said he had has no relevant financial relationships.

MILAN – Patients with psoriatic arthritis (PsA) who are using biologic and targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs) have fivefold higher risk for interstitial lung disease (ILD) than does the general population, according to the first study to explore risk of ILD in this particular patient group.

The study also found 10-fold higher risk of ILD in patients with RA who were starting a b/tsDMARD, compared with the general population, while the addition of methotrexate did not appear to be associated with increased risk for ILD in either RA nor PsA.

Becky McCall/MDedge News

Sella Aarrestad Provan, MD, of the Center for Treatment of Rheumatic and Musculoskeletal Diseases at Diakonhjemmet Hospital, Oslo, presented the results at the annual European Congress of Rheumatology.

Explaining the motivation for the study, Dr. Aarrestad Provan said that, in RA, methotrexate’s role in ILD development remained unclear, while some small studies linked b/tsDMARDs with risk for ILD. “In PsA, very few studies have explored the risk of ILD, and no systematic studies have looked at ILD risk factors in this disease.”

The researchers analyzed patient data from hospital and death registries across five Nordic countries (Denmark, Norway, Finland, Iceland, and Sweden) and compared them with general population controls. They calculated risk ratios for people who developed ILD within 5 years of starting a b/tsDMARD (with or without methotrexate).

A total of 37,010 patients with RA, 12,341 with PsA, and 569,451 members of the general population were included in the analysis, with respective disease durations of 10 and 8.9 years. Methotrexate was used along with b/tsDMARDs in 49% of patients with RA and 41% with PsA, and most patients were already on methotrexate when b/tsDMARDs were started. The tumor necrosis factor inhibitor etanercept (Enbrel) was the most commonly used b/tsDMARD in both RA and PsA, followed by infliximab (Remicade and biosimilars) and adalimumab (Humira and biosimilars).

The incidence of ILD within 5 years of starting a b/tsDMARD was 0.8% in patients with RA, 0.2% with PsA, and 0.1% in the general population, and these findings generated hazard ratios of 10.1 (95% confidence interval, 8.6-11.9) for RA and 5.0 (95% CI, 3.4-7.4) for PsA, compared with the general population as reference.

When the risk for ILD was explored according to methotrexate use in RA patients, “there was no signal of increased risk across patients using methotrexate,” Dr. Aarrestad Provan reported. When risk of ILD was explored according to b/tsDMARD use in RA patients, a signal of increased risk was observed with rituximab, she noted, “but upon adjusting for age, sex, and comorbidities, this association was no longer significant, but was still numerically increased.”

Iain McInnes, MD, PhD, vice principal, professor of rheumatology, and head of the College of Medical, Veterinary and Life Sciences at the University of Glasgow, remarked that he “loves results that are unexpected” and thanked the researcher for such an “important study.”

“For years, we’ve been interested in the potential for DMARDs to impact interstitial lung disease, with potential that drugs could make it worse, or better,” he said. “This study is wonderful and novel because first of all, there hasn’t, until now, been a direct comparison between RA and PsA in quite this way, and secondly, we haven’t really assessed whether there is a drug-related risk in PsA. Note that drug related does not necessarily imply causality.”

Regarding mechanisms, Dr. McInnes added that “epidemiologic studies suggest that PsA often coexists with the presence of cardiometabolic syndrome and obesity, which has a higher prevalence in PsA than in RA. Obesity is also related to ILD. As such, it begs the question of whether cardiometabolic, diabetes, or obesity-related features may give us a clue as to what is going on in these PsA patients.”

The research was supported by NordForsk and FOREUM. Dr. Aarrestad Provan reported serving as a consultant to Boehringer Ingelheim and Novartis and receiving grant/research support from Boehringer Ingelheim. Dr. McInnes declared no disclosures relevant to this study.

Iain McInnes, MD, PhD, vice principal, professor of rheumatology, and head of the College of Medical, Veterinary and Life Sciences at the University of Glasgow, remarked that he “loves results that are unexpected” and thanked the researcher for such an “important study.”

“For years, we’ve been interested in the potential for DMARDs to impact interstitial lung disease, with potential that drugs could make it worse, or better,” he said. “This study is wonderful and novel because first of all, there hasn’t, until now, been a direct comparison between RA and PsA in quite this way, and secondly, we haven’t really assessed whether there is a drug-related risk in PsA. Note that drug related does not necessarily imply causality.”

Regarding mechanisms, Dr. McInnes added that “epidemiologic studies suggest that PsA often coexists with the presence of cardiometabolic syndrome and obesity, which has a higher prevalence in PsA than in RA. Obesity is also related to ILD. As such, it begs the question of whether cardiometabolic, diabetes, or obesity-related features may give us a clue as to what is going on in these PsA patients.”

The research was supported by NordForsk and FOREUM. Dr. Aarrestad Provan reported serving as a consultant to Boehringer Ingelheim and Novartis and receiving grant/research support from Boehringer Ingelheim. Dr. McInnes declared no disclosures relevant to this study.

DUBLIN – Changing the way food options and information is presented on food delivery apps, as well as default smaller portions, may encourage healthier selections, lowering the calorie intake by 4%-15%, show three new randomized trials from the United Kingdom.

The prominent positioning of low-calorie menu items, and restaurants with low-calorie main meals, on a food app emerged as the most promising approach to promote healthier eating, followed by preselecting smaller portions by default, and finally calorie labels, Anna Keleher, MPA, a behavioral scientist at Nesta, London, reported at the European Congress on Obesity (ECO) meeting.

“Many out-of-home meals have more calories than meals cooked in-home and using delivery apps is linked with a higher risk of becoming overweight or obese,” she remarked. “We’re interested in understanding more about delivery apps because they can be modified at scale easily and can reach millions of people with interventions to promote healthier and more nutritious options in these settings.”

Food delivery apps have surged in use in the United Kingdom with a 55% increase since 2015; examples include Uber Eats, Just Eat, and Deliveroo. “This trend is similar in the United States, with more and more consumers using delivery apps to buy food,” said Ms. Keleher, a senior adviser at the Behavioral Insights Team, New York. 

Emma Boyland, PhD, an obesity psychologist from Liverpool (England) University, said: “Apps are an increasingly popular way for people to buy food and the virtual food environment is becoming as prominent as the physical food environment in how we go about obtaining meals.”

She highlighted the need to understand more about how food apps change the way we purchase and eat, but noted that “the work presented today” showed that “moving the position of food choices and information, as well as the brand name and imagery, influences what people end up buying and consuming.

“I think there’s a place for interventions that challenge these things and improve dietary health,” said Dr. Boyland, who chaired the session during which Ms. Keleher presented her results. “However, as we’ve seen with calorie labeling, they don’t always have the biggest effect on their own, so as is often the case, we need to take multiple actions, incorporating all the elements of the environment to make a meaningful difference.”
 

Three trials changing displays on simulated food delivery apps

“Delivery apps could reach millions of people and help us select healthier food options, and yet there is very little research looking at what works to promote healthier and more nutritious options in these settings,” Filippo Bianchi, MD, a colleague working with Ms. Keleher, said in a press release issued by ECO.

So the research team carried out a proof-of-concept testing of health-promoting interventions by developing a simulated food delivery app and asking 23,783 adults who typically use such services to choose a meal for themselves as if it were a real-life food delivery order.

“As a first step, we developed a simulated online food delivery platform to generate evidence on the effectiveness of our interventions,” Ms. Keleher explained, noting that the simulated platform included 21 restaurants and almost 600 food and drink items to choose from.

The research evaluated 14 interventions across three randomized controlled trials, displaying various food-ordering options that promoted lower-calorie options against a control. The trials investigated default choices (promoting the selection of small portion sizes through defaults, n = 6,000); positioning (promoting the selection of less calorie-dense options through positioning, n = 9,003); and labeling (promoting the selection of less calorific options through calorie labels, n = 8,780).

The primary outcome was the total number of calories in the basket at checkout. The results were adjusted for potentially confounding factors, such as body mass index, age, gender, and income.

For the trial that promoted smaller portions by default, “all of our interventions significantly reduced calorie purchases, with each additional intervention element increasing the effect sizes, which ranged from a 6% to 13% reduction in calories [–5.5% to –12.5% kcal/order; P < .05],” reported Ms. Keleher.

The second trial varied the position of both items on the menu and the order of restaurants – effectively, lower-calorie menu options were more prominent, and restaurant options with lower-calorie main meals were placed at the top of the restaurant selection page.

Ms. Keleher noted that there have been some concerns about whether this strategy would negatively affect restaurant business, so the research team counteracted this by also incorporating an option where low-calorie but high-price options were placed near the top of the display to promote healthier options but without loss of income for participating restaurants. This last intervention with low-calorie/high-price options placed near the top also led to reduced calorie intake.

“This showed that promoting low-calorie options does not necessarily mean damaging business revenue,” she said. “We hope that the industry can evolve to meet the widely recognized needs of society and consumers.”

Repositioning restaurants emerged as more effective than repositioning foods on the menu, while all interventions significantly reduced calorie purchases. “Effect sizes ranged from 6% to 15% reductions in calories purchased per order [P < .05],” reported Ms. Keleher.

The last trial tested seven calorie labels: four that changed the font size and location of the label, two that added a switch on/off filter for calorie label display, and one that was a calorie summary at checkout.

“All these standard calorie labels directionally reduced the number of excess calories with two [options] reaching statistical significance. Five out of seven labels significantly reduced calorie purchases with effect sizes ranging from 4.3% to –7.8% kcal/order (P < .05),” reported Ms. Keleher.

“This research is important for policymakers so they can understand the best way for companies to display calorie labels and what to include in regulations and guidelines,” she summarized.
 

Qualitative think-aloud study explored views around food delivery apps

Another piece of research, the think-aloud study, by the same authors, was presented at ECO, and explored how best to enhance the effectiveness and acceptability of calorie labels in food delivery apps in consultation with 20 adult delivery app users in the United Kingdom.

Researchers tried to document the range of views people have about calorie labels, including variation both between people and within an individual.

“For example, on a weekend, people might not want to engage with calories at all because they are more concerned to treat themselves, whereas at a mid-week lunch that same person might really want the ability to check the calorie content of their food,” Ms. Keleher reported.

She said that considerations varied significantly between people such that they described different ways in which calorie labeling impacted their food-ordering experience.

“Some people felt labels supported their existing intentions, whereas others felt labels built their knowledge. Still others felt calorie labels were insufficient to support their health and wanted more information, such as on macronutrients,” said Ms. Keleher, quoting one participant: “There’s no situation in which I would look at [calories]. I look at nutrients. I prefer the traffic light system [color-coding salt, fat, and sugar content],” she relayed.   

The key recommendations based on the think-aloud study included providing a filter that allows users to switch calorie labels on and off; communicating recommended energy intake per meal (that is, 600 kcal) and not just per day (that is, 2,000 kcal); and avoiding framing calorie label messaging or formatting as judgmental (for example, red fonts).

“These studies provide encouraging proof-of-concept evidence that small tweaks in delivery apps could help many people to identify and select healthier foods. Testing similar initiatives with real restaurants and delivery apps will be important to assess the long-term impact of these interventions in the real world. Further research should also explore the best way to balance desired health impacts while minimizing effects on businesses and on cost-of-living concerns for consumers,” concluded Dr. Bianchi.

DUBLIN – Substantial reductions in body weight across body mass index categories, as well as improved body composition, were achieved with tirzepatide (Mounjaro) in adults for chronic weight management, according to the latest results of the SURMOUNT-1 study.

The new analysis showed that up to 63% of participants achieved a reduction in body weight of at least 20%, and all three tirzepatide doses (5 mg, 10 mg, and 15 mg) led to substantial, clinically meaningful, and sustained body-weight reduction, compared with placebo at 72 weeks of follow-up.

Mean weight loss was –16.0%, –21.4%, and –22.5% with tirzepatide 5 mg, 10 mg, and 15 mg, compared with –2.4% for placebo (all P < .001 vs. placebo). And among participants taking the highest 15-mg dose of tirzepatide, 96%, 90%, and 78% of patients achieved weight reductions of at least 5%, 10%, and 15%.

Tirzepatide is approved in the United States and the European Union for the treatment of type 2 diabetes but is not yet approved for obesity in any country. The manufacturer of tirzepatide, Eli Lilly, intends to seek approval for the drug as an obesity treatment from the U.S. Food and Drug Administration, European Medicines Agency, and in other territories beginning in 2023.

Regardless of baseline BMI category, 9 out of 10 people achieved the greater than or equal to 5% body weight reduction threshold across all doses of tirzepatide, and at the higher doses, over one-third achieved weight loss of 25% or more.

“Similar to lifestyle and surgical treatments, participants on tirzepatide had around a threefold greater percent reduction in fat mass, compared with lean mass, resulting in an overall improvement in body composition,” reported SURMOUNT-1 co-investigator Louis Aronne, MD, Comprehensive Weight Control Center, Weill Cornell Medicine, New York.

Weight loss and body composition explored

Tirzepatide is a novel glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist that works to activate the GIP and GLP-1 receptors, respectively, found in areas of the brain important for appetite regulation, decreasing food intake, and modulating fat utilization. 

The phase 3, double-blind, randomized, controlled trial included data from 2,539 adults with a BMI greater than or equal to 30 kg/m² (class I, II, III obesity) or greater than or equal to 27 kg/m² (overweight) with one or more weight-related complications, excluding diabetes. At baseline, mean body weight was 104.8 kg, mean BMI was 38.0 kg/m², and 94.5% of participants had BMI greater than or equal to 30 kg/m².

Patients were randomized to once-weekly subcutaneous tirzepatide (5 mg, 10 mg, or 15 mg) or placebo for 72 weeks. The primary objective was to show that tirzepatide was superior to placebo in terms of percentage change in body weight and proportion of participants with body-weight reduction of greater than or equal to 5%. The percentage change from baseline body weight and proportion of participants with body weight reduction greater than or equal to 5% were also assessed across BMI categories of greater than or equal to 27 to less than 30 kg/m², greater than or equal to 30 to less than 35 kg/m² (class 1 obesity), greater than or equal to 35 to less than 40 kg/m² (class 2 obesity), and greater than or equal to 40 kg/m² (class 3 obesity).

In addition, in a retrospective subanalysis, body composition was evaluated in a subpopulation that underwent dual-energy x-ray absorptiometry, assessing change from baseline body composition within age subgroups less than 50 years (n = 99), 50-64.9 years (n = 41), and greater than or equal to 65 years (n = 20).

The average weight reduction over the 72 weeks of follow-up was –16.0%, –21.4%, and –22.5% with tirzepatide 5 mg, 10 mg, and 15 mg, compared with –2.4% for participants taking placebo (all P < .001 vs. placebo).

The percentages of participants reaching target weight reductions of greater than or equal to 5%, greater than or equal to 10%, greater than or equal to 15%, greater than or equal to 20%, and greater than or equal to 25% were recorded. Over 90% achieved greater than or equal to 5% weight loss, irrespective of BMI and tirzepatide dose, while 55.5% and 62.9% in the 10-mg and 15-mg groups achieved greater than or equal to 20% weight loss, and 35.0% and 39.7% in the 10-mg and 15-mg groups achieved greater than or equal to 25% weight loss, respectively.

By increasing BMI category, in the 10-mg group, weight loss was –18.2 kg, –21.9 kg, –22.0, and –20.7 kg; and in the 15-mg group, weight loss was –18.1kg, –21.2 kg, –24.5 kg, and –22.8 kg. Weight loss in the 5-mg group ranged from –16.6 kg to –15.9 kg from lowest to highest BMI category. 

“In the lower-weight categories, there is less weight to lose, so we see a flattening of the curve [with a] maximum of around 18%, so it may be that as we learn more about a drug that is so potent, we recognize that we don’t need to use such a high dose in people with BMI 27-30 kg/m²,” he explained. “It’s the higher BMI categories where we need the higher dose.”

As with lifestyle and surgical treatments, participants taking tirzepatide had around a three times greater percentage reduction in fat mass than lean mass, resulting in an overall improvement in body composition, reported Dr. Aronne.

“We want loss of fat, not lean mass, and we know that we lose around one part lean to three parts fat mass when on a diet and exercise regimen,” he went on to explain. “We see exactly this [balance of lean-to-fat-mass loss] here with 33.9% total fat mass reduction in the treatment group, compared with 8.2% in the placebo group.”

Visceral fat mass reduction was 40% in the treatment group, compared with 7.3% with placebo. “It’s good to see there’s more loss of visceral fat,” said Dr. Aronne. Lean mass loss was 10.9%. “So around three times greater reduction in fat over lean mass loss, resulting in overall improvement of body composition,” he reported. 

Also, in older people (≥ 65 years) there was approximately no difference in fat versus lean mass loss, compared with younger people, despite older people being more likely to lose more lean mass.

With respect to patient-reported outcomes based on the 36-item Short-Form Health Survey (SF-36), Dr. Aronne said that physical functioning scores significantly improved at 72 weeks, compared with placebo, particularly in participants with physical function limitations at baseline.

“In an interesting subanalysis, those with physical limitations at baseline showed a significant improvement versus placebo of over 5% difference [considered significant],” he added.

Safety and tolerability were previously reported in the NEJM article. The most common adverse events with tirzepatide were gastrointestinal, and adverse events causing treatment discontinuation occurred in 4.3%, 7.1%, 6.2%, and 2.6% of participants receiving 5-mg, 10-mg, and 15-mg doses or placebo, respectively.

“A revolution is coming in the treatment of obesity and cardiometabolic disease, and most physicians cannot grasp this. We’re finally getting the efficacy we’ve been looking for that will produce benefits in every realm,” concluded Dr. Aronne. “These data show that we are now hitting all the secondary endpoints and making our patients better.”

“I think this bodes well. I always envisioned a time when the treatment of obesity would come first before the treatment of cardiometabolic complications of obesity, and I think we’re on the verge of that era with semaglutide, tirzepatide, and the very exciting treatments to come.”

The SURMOUNT-1 trial was sponsored by Lilly. Dr. Aronne is cofounder, chief scientific advisor, and a member of the board of directors for Intellihealth. He is also a paid scientific advisory board member for Eli Lilly.

The manufacturer of tirzepatide, Eli Lilly, intends to seek approval for the drug as an obesity treatment from the U.S. Food and Drug Administration, European Medicines Agency, and in other territories beginning in 2023.

Regardless of baseline BMI category, 9 out of 10 people achieved the greater than or equal to 5% body weight reduction threshold across all doses of tirzepatide, and at the higher doses, over one-third achieved weight loss of 25% or more.

“Similar to lifestyle and surgical treatments, participants on tirzepatide had around a threefold greater percent reduction in fat mass, compared with lean mass, resulting in an overall improvement in body composition,” reported SURMOUNT-1 co-investigator Louis Aronne, MD, Comprehensive Weight Control Center, Weill Cornell Medicine, New York.

Weight loss and body composition explored

Tirzepatide is a novel glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist that works to activate the GIP and GLP-1 receptors, respectively, found in areas of the brain important for appetite regulation, decreasing food intake, and modulating fat utilization. 

The phase 3, double-blind, randomized, controlled trial included data from 2,539 adults with a BMI greater than or equal to 30 kg/m² (class I, II, III obesity) or greater than or equal to 27 kg/m² (overweight) with one or more weight-related complications, excluding diabetes. At baseline, mean body weight was 104.8 kg, mean BMI was 38.0 kg/m², and 94.5% of participants had BMI greater than or equal to 30 kg/m².

Patients were randomized to once-weekly subcutaneous tirzepatide (5 mg, 10 mg, or 15 mg) or placebo for 72 weeks. The primary objective was to show that tirzepatide was superior to placebo in terms of percentage change in body weight and proportion of participants with body-weight reduction of greater than or equal to 5%. The percentage change from baseline body weight and proportion of participants with body weight reduction greater than or equal to 5% were also assessed across BMI categories of greater than or equal to 27 to less than 30 kg/m², greater than or equal to 30 to less than 35 kg/m² (class 1 obesity), greater than or equal to 35 to less than 40 kg/m² (class 2 obesity), and greater than or equal to 40 kg/m² (class 3 obesity).

In addition, in a retrospective subanalysis, body composition was evaluated in a subpopulation that underwent dual-energy x-ray absorptiometry, assessing change from baseline body composition within age subgroups less than 50 years (n = 99), 50-64.9 years (n = 41), and greater than or equal to 65 years (n = 20).

The average weight reduction over the 72 weeks of follow-up was –16.0%, –21.4%, and –22.5% with tirzepatide 5 mg, 10 mg, and 15 mg, compared with –2.4% for participants taking placebo (all P < .001 vs. placebo).

The percentages of participants reaching target weight reductions of greater than or equal to 5%, greater than or equal to 10%, greater than or equal to 15%, greater than or equal to 20%, and greater than or equal to 25% were recorded. Over 90% achieved greater than or equal to 5% weight loss, irrespective of BMI and tirzepatide dose, while 55.5% and 62.9% in the 10-mg and 15-mg groups achieved greater than or equal to 20% weight loss, and 35.0% and 39.7% in the 10-mg and 15-mg groups achieved greater than or equal to 25% weight loss, respectively.

By increasing BMI category, in the 10-mg group, weight loss was –18.2 kg, –21.9 kg, –22.0, and –20.7 kg; and in the 15-mg group, weight loss was –18.1kg, –21.2 kg, –24.5 kg, and –22.8 kg. Weight loss in the 5-mg group ranged from –16.6 kg to –15.9 kg from lowest to highest BMI category. 

“In the lower-weight categories, there is less weight to lose, so we see a flattening of the curve [with a] maximum of around 18%, so it may be that as we learn more about a drug that is so potent, we recognize that we don’t need to use such a high dose in people with BMI 27-30 kg/m²,” he explained. “It’s the higher BMI categories where we need the higher dose.”

As with lifestyle and surgical treatments, participants taking tirzepatide had around a three times greater percentage reduction in fat mass than lean mass, resulting in an overall improvement in body composition, reported Dr. Aronne.

“We want loss of fat, not lean mass, and we know that we lose around one part lean to three parts fat mass when on a diet and exercise regimen,” he went on to explain. “We see exactly this [balance of lean-to-fat-mass loss] here with 33.9% total fat mass reduction in the treatment group, compared with 8.2% in the placebo group.”

Visceral fat mass reduction was 40% in the treatment group, compared with 7.3% with placebo. “It’s good to see there’s more loss of visceral fat,” said Dr. Aronne. Lean mass loss was 10.9%. “So around three times greater reduction in fat over lean mass loss, resulting in overall improvement of body composition,” he reported. 

Also, in older people (≥ 65 years) there was approximately no difference in fat versus lean mass loss, compared with younger people, despite older people being more likely to lose more lean mass.

With respect to patient-reported outcomes based on the 36-item Short-Form Health Survey (SF-36), Dr. Aronne said that physical functioning scores significantly improved at 72 weeks, compared with placebo, particularly in participants with physical function limitations at baseline.

“In an interesting subanalysis, those with physical limitations at baseline showed a significant improvement versus placebo of over 5% difference [considered significant],” he added.

Safety and tolerability were previously reported in the NEJM article. The most common adverse events with tirzepatide were gastrointestinal, and adverse events causing treatment discontinuation occurred in 4.3%, 7.1%, 6.2%, and 2.6% of participants receiving 5-mg, 10-mg, and 15-mg doses or placebo, respectively.

“A revolution is coming in the treatment of obesity and cardiometabolic disease, and most physicians cannot grasp this. We’re finally getting the efficacy we’ve been looking for that will produce benefits in every realm,” concluded Dr. Aronne. “These data show that we are now hitting all the secondary endpoints and making our patients better.”

“I think this bodes well. I always envisioned a time when the treatment of obesity would come first before the treatment of cardiometabolic complications of obesity, and I think we’re on the verge of that era with semaglutide, tirzepatide, and the very exciting treatments to come.”

The SURMOUNT-1 trial was sponsored by Lilly. Dr. Aronne is cofounder, chief scientific advisor, and a member of the board of directors for Intellihealth. He is also a paid scientific advisory board member for Eli Lilly.

DUBLIN – Substantial reductions in body weight across body mass index categories, as well as improved body composition, were achieved with tirzepatide (Mounjaro) in adults for chronic weight management, according to the latest results of the SURMOUNT-1 study.

The new analysis showed that up to 63% of participants achieved a reduction in body weight of at least 20%, and all three tirzepatide doses (5 mg, 10 mg, and 15 mg) led to substantial, clinically meaningful, and sustained body-weight reduction, compared with placebo at 72 weeks of follow-up.

Mean weight loss was –16.0%, –21.4%, and –22.5% with tirzepatide 5 mg, 10 mg, and 15 mg, compared with –2.4% for placebo (all P < .001 vs. placebo).

DUBLIN – Ear acupuncture with stimulation beads leads to weight loss and a reduction in both waist circumference and body fat percentage, when combined with restricted food intake, in men with high levels of visceral fat and overweight/obesity.

Edward Olive/Dreamstime.com

Three months of auricular acupuncture stimulation and dietary restriction led to a mean weight loss of nearly 9 kg plus a drop in waist circumference of more than 10 cm.

According to the researchers, acupuncture beads, used in Japan to augment weight loss for more than 30 years, are thought to stimulate nerves and organs that regulate appetite, satiety, hunger, and food cravings.

Findings of the observational study were presented by Takahiro Fujimoto, MD, PhD, Clinic F, Tokyo, at this year’s European Congress on Obesity.

Together with a prior study using the same intervention in women, Dr. Fujimoto and colleagues have now gathered data in more than 1,000 individuals, he said. “We wanted a method that was simple and noninvasive that would serve as a support to exercise and dietary therapy,” Dr. Fujimoto said in an interview.

“We believe there is an effect,” he asserted. “Acupuncture’s effect lies in stimulating the satiety center with benefits in helping individuals to control their food cravings and intake when reducing meals,” he said, pointing out that similar techniques have been used in patients undergoing withdrawal from drug addiction and in smoking cessation. He explained that acupuncture beads are believed to help individuals change their lifestyle habits, and added that “the relapse rate after 6 months is addressed in another paper, and it is very low.”

Professor Jason C.G. Halford, PhD, head of school at the University of Leeds, England, and president of the European Association for the Study of Obesity, commented on the findings. “There is no control group here receiving everything but the acupuncture,” he noted. “As such, it could be other elements of the intervention driving this [effect] including the act of keeping a food diary increasing awareness of one’s diet. A randomized controlled trial would be the next step.”

In women, the technique led to significantly more weight loss than in those who were untreated, and weight loss was maintained for 6 months after the end of treatment.

The researchers added that acupuncture stimulation with beads was a simpler method than traditional use of intradermal needles requiring expert acupuncturists. The stimulation is applied with 1.5-mm metal ear beads on 6 points of the outer ear (shen men, food pipe, upper stomach opening, stomach, lungs, and endocrine system) that correspond to meridian lines, and as such, restores the flow of qi by resolving any blockages or disruption. This may help with a variety of health conditions, according to the researchers. Placed on both ears, surgical tape was used to keep the beads in place to ensure participants continuously received uniform pressure on each of the six acupuncture points.

Dietary guidance was provided to participants to help reduce food intake by half, and nutritional supplements were given to compensate for any deficiencies. Participants attended twice-weekly clinic visits for bead sticking and diet progress monitoring. Body weight, body fat percentage, fat mass, lean mass, muscle mass, body mass index (BMI), and abdominal fat were assessed at the start and end of the study period.

“Since these tiny metal beads are attached to six points on the outer ear that stimulate nerves and organs which regulate appetite, satiety, and hunger, this type of acupuncture does not require complex knowledge or skill,” explained Dr. Fujimoto.

The results of the latest study, in men only, build on a prior study of more than 1,300 women who also received auricular acupuncture stimulation with beads as well as a halving of their food intake. In women, the weight loss program led to total body weight loss of 11.2% over 3 months.

At baseline, the 81 male participants, ages 21-78 years, had a mean BMI of 28.4 kg/m² and mean waist circumference of 98.4 cm. Body fat percentage was 28.2%.

After 3 months, participants lost a mean of 8.6 kg (P < .001), decreased waist circumference by a mean of 10.4 cm (P < .001), and lost a mean of 4.0% of total body fat (P < .001). Visceral fat levels also fell by 2.2 points (P < .001), from 15.2 points at baseline to 13.0 points after 3 months. (A healthy visceral fat rating is between 1 and 12 points.) BMI decreased by almost 3 kg/m² (from 28.4 at baseline to 25.5 at 3 months; P < .001).

Improvement in muscle-to-fat ratio was greater in men than women, whereas women had a greater decrease in percentage body fat than men.

“Whilst receiving ear acupuncture, the investigators asked participants to cut their food intake by half. It’s not unreasonable to expect that this major dietary change was the main reason participants lost weight,” remarked Graham Wheeler, PhD, statistical ambassador at the Royal Statistical Society, United Kingdom.

He also commented on the lack of a control group: “This study does not show us the impact of ear acupuncture on weight loss.”

Dr. Fujimoto and Dr. Halford have reported no relevant financial relationships. Dr. Wheeler is a statistical ambassador for the Royal Statistical Society, is employed by GSK, and holds an honorary senior lecturer post at Imperial College London.

DUBLIN – Nearly half (45%) of adolescents assigned to semaglutide (Wegovy), a once-weekly glucagon-like peptide-1 (GLP-1) agonist, managed to lose enough weight to drop below the clinical threshold for obesity, according to a secondary analysis of the STEP TEENS (Semaglutide Treatment Effect in People With Obesity) trial.
 

By comparison, only 12.1% of adolescents with obesity taking placebo in the trial dropped below the obesity threshold.

The study also found that 74% of participants shifted down by at least one body mass index (BMI) category after receiving the GLP-1 agonist, compared with 19% of those taking placebo.

Semaglutide shifts BMI category

In this new secondary analysis of STEP TEENS, the authors examined the effect of subcutaneous semaglutide 2.4 mg on moving adolescents from one BMI category to another, including dropping below the obesity threshold into the overweight or normal weight categories.

The study also looked at the effect of semaglutide on glucose metabolism and cardiovascular risk factors, as well as safety and tolerability. However, this particular analysis only examined adolescents with obesity (only one person had overweight, and so they were excluded), who were divided into three further subclasses: obesity class I (BMI ≥ 95th to < 20% above the 95th percentile); obesity class II (BMI ≥ 20% to < 40% above 95th percentile); and obesity class III (BMI ≥ 40% above the 95th percentile).

After a 12-week run-in period of lifestyle intervention only, a total of 200 adolescents (12-18 years) with obesity (in the top 5% of BMI) were randomized (2:1) to once-weekly subcutaneous semaglutide 2.4 mg or placebo for 68 weeks, after a 16-week titration period. All participants continued to receive counseling about healthy nutrition and were set a goal of 60 minutes per day of moderate- to high-intensity physical activity.

Dr. Kelly and colleagues determined levels of improvement in BMI category and attainment of normal weight, or overweight, BMI category by week 68.

At baseline, the percentage of participants in obesity class I, II, or III, in those taking placebo was 39.7%, 41.4%, and 19.0%, or taking semaglutide was 31.4%, 31.4%, and 37.3%, respectively.

“After 68 weeks, not a lot happened [in placebo participants]; however, 12.1% of placebo participants did drop below the obesity threshold into overweight or normal-weight categories,” reported Dr. Kelly.

Referring to participants taking semaglutide, he added that “a total of 45% of patients on semaglutide dropped below the clinical BMI cut point for obesity, such that 19.5% dropped into the overweight category and 25.4% reduced their BMI into the normal-weight category.”

Turning to obesity class, Dr. Kelly reported that of those initially with obesity class III taking placebo, 91% remained in that class and 9.1% dropped to obesity class II at week 68. For those adolescents with obesity class III taking semaglutide, 36.4% dropped to obesity class II, 18.2% dropped to obesity class I, 11% dropped below the obesity threshold, and 34.1% remained in obesity class III, he added.

For obesity class II specifically, 71% of placebo participants stayed in that category, while 12% moved up a category. “On semaglutide, over 50% (51.2%) reduced their BMI below the obesity cut point,” noted Dr. Kelly.

In obesity class I, 26% of patients taking placebo reduced their BMI below the obesity cut point. “On semaglutide, nearly 80% reduced their BMI below the obesity threshold, with 57% dropping their BMI into the normal category,” he said.

“When we looked at baseline factors that might predict the response to semaglutide or placebo, we did not find any factors that were ... significant due to small sample sizes,” he said. However, he pointed out that “females tended to respond better to semaglutide, likewise younger adolescents, and middle body weights tended to respond better to the drug, and there was a similar pattern with obesity classes.”

Commenting on the study, Jesse Bittman, MD, University of British Columbia, Vancouver, said: “Good to see more data on different populations that some semaglutide is used in and the variability in response to it. The focus on BMI was interesting because in obesity medicine we spend a lot of time telling our patients not to focus on BMIs and ‘normals’ because there are more important tools, and we see that when these become the focus of research outcomes they can become problematic.”

Asked whether rapid weight loss in adolescents might be problematic in some respects, Dr. Bittman pointed out that “one concern with these medications is whether people are going to have loss of muscle mass or malnutrition, or whether they develop eating disorders and other disturbed eating behaviors.”

Dr. Kelly has reported engaging in unpaid consulting and educational activities for Boehringer Ingelheim, Eli Lilly, Novo Nordisk, and Vivus, and receiving donated drug/placebo from Novo Nordisk and Vivus for National Institutes of Health–funded clinical trials. Dr. O’Malley has declared having received grants in the past 3 years from the Health Research Board, Department of Health, Ireland, European Association for the Study of Obesity (via a Novo Nordisk educational grant), Healthy Ireland fund, and the Royal College of Surgeons in Ireland Strategic Academic Recruitment (StAR) Programme. Dr. Bittman has reported receiving funding from Novo Nordisk, Bayer, and Bausch Health.

DUBLIN – Nearly half (45%) of adolescents assigned to semaglutide (Wegovy), a once-weekly glucagon-like peptide-1 (GLP-1) agonist, managed to lose enough weight to drop below the clinical threshold for obesity, according to a secondary analysis of the STEP TEENS (Semaglutide Treatment Effect in People With Obesity) trial.
 

By comparison, only 12.1% of adolescents with obesity taking placebo in the trial dropped below the obesity threshold.

The study also found that 74% of participants shifted down by at least one body mass index (BMI) category after receiving the GLP-1 agonist, compared with 19% of those taking placebo.

Semaglutide shifts BMI category

In this new secondary analysis of STEP TEENS, the authors examined the effect of subcutaneous semaglutide 2.4 mg on moving adolescents from one BMI category to another, including dropping below the obesity threshold into the overweight or normal weight categories.

The study also looked at the effect of semaglutide on glucose metabolism and cardiovascular risk factors, as well as safety and tolerability. However, this particular analysis only examined adolescents with obesity (only one person had overweight, and so they were excluded), who were divided into three further subclasses: obesity class I (BMI ≥ 95th to < 20% above the 95th percentile); obesity class II (BMI ≥ 20% to < 40% above 95th percentile); and obesity class III (BMI ≥ 40% above the 95th percentile).

DUBLIN – A swallowable gastric balloon (Allurion Balloon, formerly known as Elipse) combined with daily subcutaneous injections of the glucagonlike peptide 1 (GLP-1) agonist liraglutide (Saxenda, Novo Nordisk), leads to a significant average total body weight loss of 19% (18 kg or 40 lb) after around 4 months in people with obesity.

“The combination therapy [balloon and liraglutide] resulted in an additional weight loss compared to the two single treatments,” said Roberta Ienca, MD, from the Clinica Nuova Villa Claudia, Rome, who presented the findings at this year’s European Congress on Obesity.

“Despite both the balloon and liraglutide working on the early satiety feeling, the introduction of liraglutide around 1 month after [swallowing the balloon] or more frequently after 3-4 months, could sustain these feelings for a longer period of time,” she said in an interview.

Allurion Technologies

“The addition of the GLP-1 agonist therapy (liraglutide) to patients treated with the Allurion program [gastric balloon] is feasible, safe, and effective in those who need additional weight loss,” she emphasized.

The balloon stayed inside participants’ stomachs for an average of 16 weeks and liraglutide was continued for an average of 4 months, resulting in a mean reduction in body mass index (BMI) of 6.4 kg/m².

The Allurion is the world’s first and only swallowable gastric balloon placed without surgery, endoscopy, or anesthesia, and is excreted naturally after around 16 weeks.

The Allurion program delivered “excellent weight loss in individuals with overweight and obesity without going under the knife, and liraglutide has the potential to further safely enhance weight loss in cases of suboptimal adherence with the program,” Dr. Ienca said. “These two treatment approaches appear to have complementary mechanisms of action in a geographically and demographically diverse population.”

Adelardo Caballero, MD, director of the Institute of Obesity, Madrid, said that he had over 6 years of experience with the Allurion balloon in around 2,500 cases. “Over the last 3 years, we have been using Allurion balloons in combination with GLP-1 agonists. In Europe, use of the swallowable gastric balloon is common, the results are good, and it is a safe tool.”

“Using liraglutide daily in subcutaneous form is authorized in Europe and is useful in overweight and mild obesity, while use in the combination [with the balloon] is also very popular,” he explained. “In the future, the combined use of semaglutide once-weekly GLP-1 agonist or the use of dual GLP-1/gastric inhibitory polypeptide agonists [such as tirzepatide] with the swallowable intragastric balloon Allurion program or endoscopic sleeve gastroplasty will improve results,” he added.
 

Average 40-lb weight loss with balloon and liraglutide

For the current study, data from three international multidisciplinary obesity centers (in Italy, Spain, and Egypt) were retrospectively analyzed. All 181 patients received the combination of the Allurion balloon and liraglutide, with the latter added 4-16 weeks after swallowing the balloon.

During a 20-minute outpatient visit, participants swallowed the balloon, which was filled with liquid after reaching the stomach, and placement was confirmed by x-ray. The balloon remained inserted for around 15-17 weeks (mean 16 weeks) before natural excretion. All patients received liraglutide once daily for 1-6 months (mean 4 months). After excreting the balloon, patients started the Mediterranean diet for weight maintenance and were followed for at least 6 months.

Patients were monitored for weight loss, percentage total body weight loss, percentage excess weight loss, and BMI reduction. The timing of combining drug therapy with the Allurion program, metabolic results, and adverse event data were collected. However, Dr. Ienca explained that “the study was preliminary and aimed to evaluate feasibility and results of a combined treatment, so we didn’t collect long-term data.”

Liraglutide was mostly added in cases of unsatisfactory weight loss to boost weight reduction in patients with high BMIs, to sustain weight maintenance, and to aid diabetes control in patients with satisfactory weight loss. There were no criteria for time of onset of drug therapy in terms of a time point or percentage weight loss.

Before treatment, mean weight was 94.8 ± 21 kg and mean BMI was 33.7 ± 6.2 kg/m². After 4 months of balloon treatment, weight loss, percentage total body weight loss, percentage excess weight loss, and decrease in BMI were 13.1 ± 7 kg, 13.9% ± 7.7%, 74.3% ± 57.1%, and 4.5 ±1.4 kg/m² respectively.

After a mean duration of 4 months of liraglutide treatment (in addition to the gastric balloon), participants lost on average 18.1 ± 12.1 kg overall and 18.7% ± 12% of their initial total body weight. They shed 99.4% ± 84.9% of excess weight and reduced BMI by 6.4 ± 5.9 kg/m².

Dr. Ienca explained that the study did not explore the separate contributions of the balloon or drug therapy to weight loss. “However, existing literature shows that the Allurion program leads to a weight loss of approximately 14% of total body weight after 4 months, while liraglutide studies report 12% of total body weight loss at 1 year,” he noted.

When describing the mechanism of action, Dr. Ienca said the Allurion balloon induces satiety and delays gastric emptying but the feeling of satiety starts to decrease after the first month. “For a few patients, this feeling of satiety decreases more rapidly or they have more difficulty putting in place new alimentary habits. In these patients, the addition of liraglutide gives an additional boost to support this behavioral change.”

Liraglutide-related adverse events included nausea (16.5%), diarrhea (3.3%), constipation (2.2%), and headache (1.7%), as well as drug discontinuation due to tachycardia/chest pain (1.1%) and gastrointestinal symptoms (1.1%).

Balloon removal because of intolerance occurred in 1.1% of patients, gastric dilation in 0.5%, and early balloon deflation in 0.5%. Other expected balloon-related adverse events included nausea, vomiting, and abdominal cramps.

The researchers note that the Allurion program offers a more acceptable option to balloon placement by endoscopy.

“The ease of use, low rate of adverse events, and potentially lower cost of the Allurion Program could enable much wider application of this critical intervention, and ultimately, help the millions who struggle with obesity and its associated health complications.”

When describing the mechanism of action, Dr. Ienca said the Allurion balloon induces satiety and delays gastric emptying but the feeling of satiety starts to decrease after the first month. “For a few patients, this feeling of satiety decreases more rapidly or they have more difficulty putting in place new alimentary habits. In these patients, the addition of liraglutide gives an additional boost to support this behavioral change.”

Liraglutide-related adverse events included nausea (16.5%), diarrhea (3.3%), constipation (2.2%), and headache (1.7%), as well as drug discontinuation due to tachycardia/chest pain (1.1%) and gastrointestinal symptoms (1.1%).

Balloon removal because of intolerance occurred in 1.1% of patients, gastric dilation in 0.5%, and early balloon deflation in 0.5%. Other expected balloon-related adverse events included nausea, vomiting, and abdominal cramps.

The researchers note that the Allurion program offers a more acceptable option to balloon placement by endoscopy.

“The ease of use, low rate of adverse events, and potentially lower cost of the Allurion Program could enable much wider application of this critical intervention, and ultimately, help the millions who struggle with obesity and its associated health complications.”

In one of the first studies to examine this phenomenon, metabolically unhealthy obesity is associated with an increased risk, around 1.5-fold higher, of any obesity-related cancer, and an even higher risk, two- to threefold higher, for specific cancers, such as endometrial, liver, and renal cell cancers, compared with metabolically healthy normal weight.

Even in people with so-called “metabolically healthy” obesity, the risk for overall obesity-related cancer is increased, compared with normal-weight, metabolically healthy individuals; however, the associations here are weaker than in people with metabolically unhealthy obesity.

“The type of metabolic obesity phenotype is important when assessing obesity-related cancer risk,” lead researcher Ming Sun, PhD, from Lund University, Malmö, Sweden, said in an interview. “In general, metabolic aberrations further increased the obesity-induced cancer risk, suggesting that obesity and metabolic aberrations are useful targets for prevention.”

“This synergy means that when obesity and metabolic unhealth occur together, that’s particularly bad,” added Tanja Stocks, PhD, senior author, also of Lund University.

“But the data also highlight that even obesity and overweight alone comprise an increased risk of cancer,” Dr. Stocks noted.

Dr. Sun said the findings have important public health implications, suggesting that “a significant number of cancer cases could potentially be prevented by targeting the coexistence of metabolic problems and obesity, in particular for obesity-related cancers among men.”

The results will be presented as a poster by Dr. Sun at the European Congress on Obesity 2023, being held in Dublin, and have been published in the Journal of the National Cancer Institute.
 

Metabolically unhealthy obesity worst for cancer risks

Andrew G. Renehan, PhD, FRCS, professor of cancer studies and surgery, University of Manchester, England, welcomed the new work, saying it addresses the issue with very large study numbers. “[It] nicely demonstrates that there are clear examples where metabolically unhealthy overweight and obese phenotypes have increased cancer risk relative to [metabolically] healthy overweight and obese phenotypes,” he said.

“There is a clear need for clinically based research addressing these hypotheses ... but these studies will additionally need to factor in other dimensions such as the selection of treatment for metabolic aberrations, both medical and surgical, and the consequent metabolic control resulting from these interventions,” Dr. Renehan observed.

Vibhu Chittajallu, MD, a gastroenterologist based at University Hospitals Cleveland Medical Center, said it was beneficial to see another study further validating the association of obesity with the development of obesity-associated cancers.

“This is an interesting study [because it focuses] on the role of metabolic syndrome in obesity and how it affects the risk of development of obesity-associated cancers,” he said in an interview.

“I believe that the results of this study further strengthen the need for improved management of obesity and metabolic syndrome to reduce the risk of obesity-associated cancer formation that plays a role in preventable and premature deaths in adult patients with obesity.”
 

Synergy between metabolic aberrations and obesity, and cancer risk

Dr. Sun and colleagues note that obesity is an established risk factor for several cancers. It is often accompanied by metabolic aberrations, which have been a commonly proposed mechanism to link obesity with cancer. During the last decade, obesity with or without metabolic aberrations – commonly termed “metabolically unhealthy” or “healthy obesity” – has been extensively investigated in the cardiovascular field; however, studies regarding cancer are limited.

According to Dr. Sun, this new study is the first to look at the synergistic effect of unhealthy metabolism and body mass index – the latter was further categorized as normal weight (BMI < 25 kg/m2), overweight (BMI < 30) and obesity (BMI ≤ 30) – and the association with cancer risk, both overall and in relation to site-specific cancers.

Data were drawn from 797,193 European individuals (in Norway, Sweden, and Austria), of whom 23,630 developed an obesity-related cancer during the follow-up period. A metabolic score comprising mid-blood pressure, plasma glucose, and triglycerides was used to provide a measure of healthy or unhealthy metabolic status. Relative risks (hazard ratios) for overall and site-specific cancers were determined. Comparisons were made with metabolically healthy people of normal weight (effectively controls).

When different metabolic scores and BMIs were combined, participants fell into six categories: metabolically unhealthy obesity (6.8% of participants); metabolically healthy obesity (3.4%), metabolically unhealthy overweight (15.4%), metabolically healthy overweight (19.8%), metabolically unhealthy normal weight (12.5%), and metabolically healthy normal weight (42.0%).

Metabolically unhealthy women with obesity had a hazard ratio of 1.43 for overall obesity-related cancers, compared with metabolically healthy women of normal weight. Of particular note were risks of two cancer types in women with metabolically unhealthy obesity: renal cancer, with an HR of 2.43, and endometrial cancer, with an HR of 3.0, compared with controls.

Even in metabolically healthy women with obesity, compared with metabolically healthy women of normal weight, there was an increased risk of endometrial cancer, with an HR of 2.36.

“If you look at individual cancers, in particular endometrial cancer, this seems to be very much driven by obesity and not so much by the metabolic factor,” remarked Dr. Stocks.

In males, compared with metabolically healthy men of normal weight, metabolically unhealthy men with obesity had an overall obesity-related cancer risk HR of 1.91. Specifically, the risk of renal cell cancer was more than doubled, with an HR of 2.59. The HR for colon cancer was 1.85, and that for rectal cancer and pancreatic cancer was similar, both having HRs of 1.32.

Again, risk was lower in metabolically healthy men with obesity, although still higher than for metabolically healthy normal-weight men.
