Cancer loses … by a nose

Since the human nose is unpredictable at best, we’ve learned to rely on animals for our detailed nozzle needs. But researchers have found the next best thing to man’s best friend to accurately identify cancers.

A team at the University of Pennsylvania has developed an electronic olfaction, or “e-nose,” that has a 95% accuracy rate in distinguishing benign and malignant pancreatic and ovarian cancer cells from a single blood sample. How?

The e-nose system is equipped with nanosensors that are able to detect the volatile organic compounds (VOCs) emitted by cells in a blood sample. Not only does this create an opportunity for an easier, noninvasive screening practice, but it’s fast. The e-nose can distinguish VOCs from healthy to cancerous blood cells in 20 minutes or less and is just as effective in picking up on early- and late-stage cancers.

Do you think this is a (food) game?

Dieting and eating healthy is tough, even during the best of times, and it has not been the best of times. With all respect to Charles Dickens, it’s been the worst of times, full stop. Millions of people have spent the past year sitting around their homes doing nothing, and it’s only natural that many would let their discipline slide.

Naturally, the solution to unhealthy eating habits is to sit down and play with your phone. No, that’s not the joke, the Food Trainer app, available on all cellular devices near you, is designed to encourage healthy eating by turning it into a game of sorts. When users open the app, they’re presented with images of food, and they’re trained to tap on images of healthy food and pass on images of unhealthy ones. The process takes less than 5 minutes.

It sounds really simple, but in a study of more than 1,000 people, consumption of junk food fell by 1 point on an 8-point scale (ranging from four times per day to zero to one time per month), participants lost about half a kilogram (a little over one pound), and more healthy food was eaten. Those who used the app more regularly, along the lines of 10 times per month or more, saw greater benefits.

It’s time for a little mass kickin’

The universe, scientists tell us, is a big place. Really big. Chromosomes, scientists tell us, are small. Really small. But despite this very fundamental difference, the universe and chromosomes share a deep, dark secret: unexplained mass.

This being a medical publication, we’ll start with chromosomes. A group of researchers measured their mass with x-rays for the first time and found that “the 46 chromosomes in each of our cells weigh 242 picograms (trillionths of a gram). This is heavier than we would expect, and, if replicated, points to unexplained excess mass in chromosomes,” Ian K. Robinson, PhD, said in a written statement.

A photo finish for the Smart Toilet

We know that poop can tell us a lot about our health, but new research by scientists at Duke University is really on a roll. Their Smart Toilet has been created to help people keep an eye on their bowel health. The device takes pictures of poop after it is flushed and can tell whether the consistency is loose, bloody, or normal.

The Smart Toilet can really help people with issues such as irritable bowel syndrome and inflammatory bowel disease by helping them, and their doctors, keep tabs on their poop. “Typically, gastroenterologists have to rely on patient self-reported information about their stool to help determine the cause of their gastrointestinal health issues, which can be very unreliable,” study lead author Deborah Fisher said.

The U.S. Department of Justice (DOJ) on May 26 announced charges against 14 defendants across the country who allegedly engaged in health care fraud schemes that exploited the COVID-19 pandemic and resulted in over $143 million in false billings to Medicare.

Among the defendants, a DOJ news release said, were a telemedicine company executive, a physician, marketers, and medical business owners.

In addition, the Centers for Medicare and Medicaid Services separately announced that it had taken “adverse administrative actions” against more than 50 providers for their involvement in fraud schemes related to COVID-19 or the abuse of CMS programs that were designed to encourage access to medical care during the pandemic.

Several of the defendants allegedly offered COVID-19 tests to Medicare beneficiaries in senior living facilities, drive-through COVID-19 testing sites, and medical offices to induce the beneficiaries to provide their personal identifying information and a saliva or a blood sample.

The DOJ charges claim the defendants then misused the information and the samples to submit claims to Medicare for unrelated, medically unnecessary, and far more expensive lab tests, including cancer genetic testing, allergy testing, and respiratory pathogen panel tests.

In some cases, it’s alleged, the lab results were not provided to the individuals in a timely fashion or were not reliable.

Other defendants are charged with exploiting temporary changes in CMS telehealth regulations that were designed to increase access to health care during the pandemic. In these cases, which the DOJ said were the first charges related to the expansion of telehealth under the COVID-19 emergency declaration, the defendants allegedly submitted false and fraudulent claims to Medicare for sham telemedicine encounters that did not occur.

“As part of these cases, medical professionals are alleged to have [been] offered and paid bribes in exchange for the medical professionals’ referral of unnecessary testing,” the DOJ news release said. However, no physicians were identified by the department.

Commenting on this aspect of the law enforcement action, FBI Director Christopher Wray said in the release: “Medical providers have been the unsung heroes for the American public throughout the pandemic. It’s disheartening that some have abused their authorities and committed COVID-19–related fraud against trusting citizens. The FBI, along with our federal law enforcement and private sector partners, are committed to continuing to combat health care fraud and protect the American people.”

The law enforcement action includes the third set of criminal charges related to the misuse of Provider Relief Fund monies, according to the release.

More than 340 individuals were charged in September 2020 with submitting $6 billion in fraudulent claims to federal health care programs and private insurers for telehealth consultations and substance abuse treatment. About $4.5 billion of that was related to telehealth, as reported by this news organization.

The new criminal charges were brought in federal district courts in Arkansas, California, Louisiana, Florida, New Jersey, and New York.
 

Case summaries

The DOJ provided several case summaries. One defendant, lab owner Billy Joe Taylor of Lavaca, Ark., was charged with participating in a scheme to defraud the government of over $42 million by filing false claims that were billed in combination with COVID-19 testing claims. He also allegedly billed for tests that were not performed.

Petros Hannesyan of Burbank, Calif., the owner of a home health agency, was charged with obtaining over $229,000 from COVID-19 relief programs under false pretenses. His firm allegedly misappropriated funds from the CARES Act Provider Relief Fund and submitted false loan applications and a false loan agreement to the Economic Injury Disaster Loan Program.

Michael Stein and Leonel Palatnik of Palm Beach County, Fla., were charged in a connection with an alleged $73 million conspiracy to defraud the government and to pay and receive health care kickbacks during the pandemic.

Mr. Stein, who owned a “purported” consulting company, and Mr. Palatnik, who owned testing labs in Texas, allegedly exploited Medicare’s waiver of telehealth restrictions “by offering telehealth providers access to Medicare beneficiaries for whom they could bill consultations. In exchange, these providers agreed to refer beneficiaries to [Mr. Palatnik’s] laboratories for expensive and medically unnecessary cancer and cardiovascular genetic testing.”

Rurioctocog alfa pegol prophylaxis was linked to fewer bleeding episodes in people with hemophilia A when it targeted higher levels of factor VIII (FVIII) troughs, according to a report published in Blood (2021;137[13]:1818-27).

Earlier studies demonstrated that the treatment effectively prevented bleeds with an acceptable safety profile in people with hemophilia A. The current prospective, randomized, open label PROPEL trial compared safety and efficacy of two target FVIII troughs in this population. Targeting 1%-3% and 8%-12% FVIII troughs was efficacious, with fewer bleeds in the latter arm and acceptable safety across both, according to Robert Klamroth, MD, of Vivantes Klinikum Friedrichshain, Berlin, and colleagues.

The PROPEL trial (NCT02585960) population comprised 155 patients with hepatitis A, aged 12-65 years, with severe disease and an annualized bleeding rate of at least 2 during the 12 months before enrollment in the study. All had previous FVIII treatment. Patients were randomized to 12 months’ pharmacokinetic rurioctocog alfa pegol prophylaxis targeting FVIII troughs of 1%-3% (reference arm) or 8%-12%.

The primary endpoint was absence of bleeds during the second 6-month period. A total of 95 patients completed the protocol.
 

Promising results

In the 1%-3% and 8%-12% arms, the proportions of patients who completed the protocol and had no bleeds were 40% and 67% respectively (P = .015). Serious adverse events occurred in 7 of 115 (6%) patients, including one treatment-related event in the 8%-12% arm. There were no deaths, serious thrombotic events, or adverse event-related discontinuations.

“Targeting 8% to 12% FVIII troughs resulted in a higher proportion of [patients] with no bleeds than prophylaxis that targeted 1% to 3% FVIII troughs. These results support the hypothesis that an elevated FVIII trough can benefit [patients]without changing the safety profile,” the researchers reported. Personalized treatment in this patient population should be considered, they added.
 

Problems remain

In an invited commentary, Christine L. Kempton, MD, of Emory University, Atlanta, pointed out that the study did not answer the question of what trough level is best, and that the target trough level may be up to a patient’s individual clinician to decide. “Many participants (42%) treated with the target trough level of 1% to 3% had no bleeding events during the study period, but some (38%) continued to have bleeding events despite higher target trough levels,” Dr. Kempton wrote. She added that, beyond this concern, the presence of subclinical bleeding is difficult to study and quantify, but its presence is supported in the literature by magnetic resonance imaging that demonstrated joint damage despite a lack of clinically evident bleeding.

“Thus, targeting zero clinical bleeding events does not mean that all joint disease, dysfunction, and pain will be eliminated. This reality underscores the need for better, not just more convenient, therapies,” she concluded.

The authors reported numerous relationships with a variety of pharmaceutical companies including grants, honoraria, and participation in speakers bureaus. Dr. Kempton reported honoraria from Takeda, Spark, Octapharma, and Pfizer, and research grants from Novo Nordisk.

A subcutaneous dose of the second-generation glycoprotein IIb/IIIa inhibitor RUC-4 achieved rapid dose-dependent platelet inhibition in patients with ST-segment elevation MI (STEMI) undergoing stenting in the CEL-02 study.

Platelet inhibition occurred within 15 minutes among the 27 patients, and wore off rapidly, with almost 50% of platelet function recovered within 122 minutes.

The drug was well tolerated, with no thrombocytopenia in the first 72 hours after administration, one injection-site reaction, and two major bleeds likely caused by catheter-based trauma to the proximal radial artery, reported Jurrien ten Berg, MD, PhD, St. Antonius Hospital, Nieuwegein, the Netherlands.

The results were reported during the annual meeting of the European Association of Percutaneous Cardiovascular Interventions (EuroPCR 2021) and published simultaneously in EuroIntervention.

Dr. ten Berg noted that there is a need for drugs like RUC-4 in the early treatment of STEMI because oral P2Y12 inhibitors have a “seriously delayed” onset by about 2-4 hours. Prehospital use of the glycoprotein inhibitor (GPI) tirofiban was shown to improve reperfusion and late outcomes in the ON-TIME 2 trial, but GPIs require continuous intravenous administration and are associated with thrombocytopenia.

“Since RUC-4 is unique among small-molecule GPI in not inducing the receptor to undergo a major conformational change that has been implicated in the development of thrombocytopenia, it is possible that RUC-4 may be associated with fewer episodes of thrombocytopenia than current GPI,” the authors wrote.

RUC-4, also called zalunfiban, can be delivered with a single subcutaneous dose and, in a phase 1 study, demonstrated platelet inhibition within 15 minutes and was well tolerated up to a dose of 0.075 mg/kg among healthy volunteers and patients with stable coronary artery disease on aspirin.

In the CEL-02 study, 27 STEMI patients received a weight-adjusted subcutaneous injection of RUC-4 before primary percutaneous coronary intervention (PCI) in escalating doses of 0.075 mg/kg, 0.090 mg/kg, and 0.110 mg/kg. Patients were given standard treatment in the ambulance, which included aspirin (93%), ticagrelor (93%), and unfractionated heparin (96%). The activated clotting time was less than 200 seconds in 92% of patients who received additional heparin during cardiac catheterization.

The patients’ mean age was 62 years, 26% were women, and 96% were White. Pharmacodynamic data were available for 24 patients.

The average platelet inhibition 15 minutes after the injection was 77.5%, 87.5%, and 91.7%, respectively, for the three escalating doses (P = .002 for trend).

The primary endpoint of at least 77% inhibition of the iso-TRAP channel – which corresponds to 80% inhibition of light transmission aggregometry stimulated by 20 mcM adenosine diphosphate within 15 minutes – was achieved in three of eight patients at the lowest dose and in seven of eight patients at the middle and highest doses.

“Single-dose subcutaneous RUC-4 induces a fast, potent dose-dependent response of platelet inhibition in patients with STEMI presenting for primary PCI,” Dr. ten Berg concluded. “It is therefore promising for prehospital platelet inhibition in STEMI patients, and the results support further research on clinical benefit.”

The double-blind, randomized phase 2b CELEBRATE trial is underway, evaluating 1,668 STEMI patients treated with a 0.110 mg/kg or 0.130 mg/kg dose of RUC-4 or placebo in the ambulance. The coprimary outcomes are restoration of coronary artery blood flow and resolution of ST-segment deviation post-PCI/angiography. Primary completion is set for March 2023.

Marco Valgimigli, MD, who was not involved in the study, said in an interview that RUC-4 has “some theoretical advantages, compared with conventional IIb/IIIa inhibitors, namely the absence of thrombocytopenia which is, however, relatively rare, especially with tirofiban or eptifibatide.”

The subcutaneous approach may also offer an advantage. Yet, if the administration of RUC-4 is “to happen in the ambulance – a setting where an IV line is usually established – whether the subcutaneous versus IV administration of the treatment proves to be advantageous remains to be seen,” said Dr. Valgimigli, from Cardiocentro Ticino Institute, Ente Ospedaliero Cantonale, Lugano, Switzerland.

“We would need to see the results of large randomized trials embracing this treatment option before a clinical decision can be made, especially considering that IIb/IIa inhibitors in the ambulance have been tested in the past but ultimately abandoned,” he said.

Limitations of the study are its open-label design, the fact that iso-TRAP channel assay data were not reported by the VeryifyNow instrument and had to be calculated from the raw data, and the fact that the timing of the RUC-4 injection immediately before PCI does not fully resemble the expected use of RUC-4 in clinical practice, where RUC-4 would be administered at the same time as the aspirin, ticagrelor, and heparin, and about an hour before PCI, ten Berg and colleagues wrote.

Dr. ten Berg reported receiving lecture or consultancy fees from AstraZeneca, Eli Lilly, Daiichi Sankyo, The Medicines Company, AccuMetrics, Boehringer Ingelheim, Bristol-Myers Squibb, Pfizer, Bayer, Ferrer, and Idorsia, and institutional research grants from ZonMw and AstraZeneca.

A subcutaneous dose of the second-generation glycoprotein IIb/IIIa inhibitor RUC-4 achieved rapid dose-dependent platelet inhibition in patients with ST-segment elevation MI (STEMI) undergoing stenting in the CEL-02 study.

Platelet inhibition occurred within 15 minutes among the 27 patients, and wore off rapidly, with almost 50% of platelet function recovered within 122 minutes.

The drug was well tolerated, with no thrombocytopenia in the first 72 hours after administration, one injection-site reaction, and two major bleeds likely caused by catheter-based trauma to the proximal radial artery, reported Jurrien ten Berg, MD, PhD, St. Antonius Hospital, Nieuwegein, the Netherlands.

The results were reported during the annual meeting of the European Association of Percutaneous Cardiovascular Interventions (EuroPCR 2021) and published simultaneously in EuroIntervention.

Dr. ten Berg noted that there is a need for drugs like RUC-4 in the early treatment of STEMI because oral P2Y12 inhibitors have a “seriously delayed” onset by about 2-4 hours. Prehospital use of the glycoprotein inhibitor (GPI) tirofiban was shown to improve reperfusion and late outcomes in the ON-TIME 2 trial, but GPIs require continuous intravenous administration and are associated with thrombocytopenia.

The U.S. Food and Drug Administration has approved a once-daily oral medication, which is a combination of olanzapine and samidorphan (Lybalvi, Alkermes), for the treatment of schizophrenia and bipolar I disorder.

The drug is approved for the treatment of adults with schizophrenia and for adults with bipolar I disorder as a maintenance monotherapy or to treat acute manic or mixed episodes, as either monotherapy or an adjunct to lithium or valproate.

An atypical antipsychotic, the drug is a combination of olanzapine, an established antipsychotic medication, and samidorphan, a new chemical entity.

“Schizophrenia and bipolar I disorder are complex, chronic diseases, and there remains a persistent need for new medications with proven efficacy and safety. Olanzapine, a highly efficacious atypical antipsychotic, is associated with significant side effects, including weight gain that may impact patients’ treatment experiences and limit its use. With the efficacy of olanzapine and evidence of less weight gain in patients with schizophrenia, Lybalvi brings a welcome new addition to our medication arsenal,” René S. Kahn, MD, PhD, Esther and Joseph Klingenstein professor & chair, department of psychiatry and Behavioral Health System at the Icahn School of Medicine at Mount Sinai, New York, said in a company press release.

In a clinical development program, the drug demonstrated antipsychotic efficacy, safety, and tolerability, including significantly less weight gain than olanzapine in patients with schizophrenia in the ENLIGHTEN-2 study.

The FDA approved Lybalvi under the 505(b)(2) regulatory pathway based on data from 27 clinical studies, including 18 studies evaluating Lybalvi and nine studies evaluating samidorphan alone and the FDA’s findings of the safety and effectiveness of olanzapine in the treatment of bipolar I disorder and schizophrenia. Data suggest that olanzapine-associated weight gain is disease independent, the company reports.

“People living with schizophrenia or bipolar I disorder must evaluate both efficacy and tolerability when making treatment decisions,” Paul Gionfriddo, president and CEO of Mental Health America, said in the same company press release. “We are grateful that companies like Alkermes are driven to continue developing new treatment options in psychiatry that seek to address unmet needs of our community, and we applaud the FDA for considering the experiences of individuals living with these conditions.” 

Alkermes expects to make Lybalvi available for patients in the fourth quarter of 2021.

Combining minimally invasive endoscopic sleeve gastroplasty with a weekly injection of the glucagonlike peptide–1 agonist semaglutide (Ozempic, Novo Nordisk) leads to significantly greater weight loss than ESG alone in patients with diabetes and excess weight who are not candidates for bariatric surgery, new research shows.

During minimally invasive ESG, a flexible endoscope equipped with an endoscopic suturing device is inserted down the esophagus and into the stomach. The endoscopist then applies the sutures to the upper portion of the stomach, minimizing its size to restrict the amount of food a patient can ingest.

“Our stomachs can stretch back a bit, but we can use the suturing device again,” explained the lead investigator of the research Anna Carolina Hoff, MD, founder and clinical director of Angioskope Brazil in São José dos Campos.

“It’s important that patients with diabetes lose as much weight as possible because, if they lose about 10% of their total body weight, they have a great improvement in their glycemic levels, and some patients can even stop taking their [antidiabetic] medications,” Dr. Hoff said in an interview.

“And we found that by adding the GLP-1 agonist [semaglutide], we could increase weight loss from, on average, about 16%-18% of total body weight with ESG alone to up to 27%, so it’s a great metabolic combination,” she noted.

Dr. Hoff presented the findings at the annual Digestive Disease Week® (DDW).

Asked to comment, Scott Kahan, MD, MPH, director, National Center for Weight and Wellness, George Washington University, Washington, cautioned that it’s still early days for minimally invasive ESG.

“It is reasonable to assume that the long-term outcomes [with ESG] won’t be as good or durable over time as with bariatric surgery, but ... we will have to see.”

However, “we know that, typically, combinations of therapeutic options work better than a one-off option, so I think the real benefit of this study – outside the specific procedure and this specific medication – is that it is a very valuable proof-of-principle study showing that combinations do work better,” Dr. Kahan said in an interview.
 

Minimally invasive endoscopic sleeve gastroplasty

ESG is a surrogate for laparoscopic sleeve gastrectomy that can offer the benefits of such a procedure to those who don’t qualify for, or don’t wish to pursue, bariatric surgery. It can be performed at an earlier stage of disease, in those with a body mass index of 30 mg/kg², whereas generally people are not offered bariatric procedures unless they have a BMI of at least 35 with comorbidities or a BMI of at least 40 if they do not have comorbidities.

Subcutaneous semaglutide is already approved for the treatment of type 2 diabetes in adults at doses of up to 1 mg/week; higher doses are needed for weight loss. Novo Nordisk has been investigating higher doses for weight loss in the STEP trial program, which is now complete, and the company has submitted the data to the Food and Drug Administration and European Medicines Agency for an additional indication of adults with obesity (BMI ≥30) or who are overweight (BMI ≥27) and who have at least one weight-related comorbidity, as an adjunct to a reduced-calorie diet and increased physical activity, with a decision expected soon.

Novo Nordisk has also developed an oral form of semaglutide, which has been approved as a once-daily agent for type 2 diabetes (Rybelsus) in doses of 7 mg and 14 mg to improve glycemic control along with diet and exercise. It is the first GLP-1 agonist available in tablet form.
 

Patients lost fat mass as well as excess weight

The Brazilian study involved 58 patients with obesity or overweight who also had diabetes and were undergoing minimally invasive ESG; they were further randomized to receive semaglutide or placebo.

The GLP-1 agonist (or sham placebo) was initiated 1 month after participants had undergone the procedure and patients were monitored each month for weight loss and type of fat loss achieved with the combination versus ESG alone. The initial dose of semaglutide used was 0.25 mg subcutaneous a week but could be titrated up to a maximum dose of 1.5 mg.

At the end of 11 months of active treatment versus placebo (12 months after ESG), patients who received additional semaglutide lost 86.3% of their excess body weight – the amount of weight patients needed to lose to reach normal BMI – compared with only 60.4% for ESG controls.

Specifically, the mean percentage total body weight loss at the end of 12 months was 25.2% for those in the combination group, compared with 18.6% for those treated with ESG alone (P < .001).

More importantly, patients in the combination group lost 12.6% of their body fat mass, compared with 9% for ESG controls, while mean A1c levels fell more in those treated with additional semaglutide compared with controls (P = .0394).

Indeed, five patients in the combination group reverted to a nondiabetic state and were able to discontinue antidiabetic medications altogether, Dr. Hoff noted.

“Our main goal is not just to lose weight but to lose body mass fat, which is very different from just losing weight,” she explained.

If patients lose weight but still maintain a high percentage of body fat mass, they have what she refers to as “sarcopenic obesity” because in this state patients have lost a lot of muscle mass but still have high levels of metabolically active visceral fat. Among many other inflammatory complexes, metabolically active visceral fat contains a large number of inflammasomes, and it is the latter that have been associated with obesity-related cancers. 

“Obesity is a progressive disease, so what we are trying to do here is buy time for patients so they do not progress to [bariatric] surgery, and this approach gives patients a chance to act earlier before obesity takes over and more metabolic consequences occur,” Dr. Hoff emphasized.

So, when combined with semaglutide, “we now have a minimally invasive procedure that can be just as successful [as surgery] and which can be made available to even more people looking to lose a significant amount of weight,” she concluded.

Dr. Hoff and Dr. Kahan have reported no relevant financial relationships.

Specifically, the mean percentage total body weight loss at the end of 12 months was 25.2% for those in the combination group, compared with 18.6% for those treated with ESG alone (P < .001).

More importantly, patients in the combination group lost 12.6% of their body fat mass, compared with 9% for ESG controls, while mean A1c levels fell more in those treated with additional semaglutide compared with controls (P = .0394).

Indeed, five patients in the combination group reverted to a nondiabetic state and were able to discontinue antidiabetic medications altogether, Dr. Hoff noted.

“Our main goal is not just to lose weight but to lose body mass fat, which is very different from just losing weight,” she explained.

If patients lose weight but still maintain a high percentage of body fat mass, they have what she refers to as “sarcopenic obesity” because in this state patients have lost a lot of muscle mass but still have high levels of metabolically active visceral fat. Among many other inflammatory complexes, metabolically active visceral fat contains a large number of inflammasomes, and it is the latter that have been associated with obesity-related cancers. 

“Obesity is a progressive disease, so what we are trying to do here is buy time for patients so they do not progress to [bariatric] surgery, and this approach gives patients a chance to act earlier before obesity takes over and more metabolic consequences occur,” Dr. Hoff emphasized.

So, when combined with semaglutide, “we now have a minimally invasive procedure that can be just as successful [as surgery] and which can be made available to even more people looking to lose a significant amount of weight,” she concluded.

Dr. Hoff and Dr. Kahan have reported no relevant financial relationships.

Combining minimally invasive endoscopic sleeve gastroplasty with a weekly injection of the glucagonlike peptide–1 agonist semaglutide (Ozempic, Novo Nordisk) leads to significantly greater weight loss than ESG alone in patients with diabetes and excess weight who are not candidates for bariatric surgery, new research shows.

During minimally invasive ESG, a flexible endoscope equipped with an endoscopic suturing device is inserted down the esophagus and into the stomach. The endoscopist then applies the sutures to the upper portion of the stomach, minimizing its size to restrict the amount of food a patient can ingest.

“Our stomachs can stretch back a bit, but we can use the suturing device again,” explained the lead investigator of the research Anna Carolina Hoff, MD, founder and clinical director of Angioskope Brazil in São José dos Campos.

“It’s important that patients with diabetes lose as much weight as possible because, if they lose about 10% of their total body weight, they have a great improvement in their glycemic levels, and some patients can even stop taking their [antidiabetic] medications,” Dr. Hoff said in an interview.

“And we found that by adding the GLP-1 agonist [semaglutide], we could increase weight loss from, on average, about 16%-18% of total body weight with ESG alone to up to 27%, so it’s a great metabolic combination,” she noted.

Dr. Hoff presented the findings at the annual Digestive Disease Week® (DDW).

Asked to comment, Scott Kahan, MD, MPH, director, National Center for Weight and Wellness, George Washington University, Washington, cautioned that it’s still early days for minimally invasive ESG.

“It is reasonable to assume that the long-term outcomes [with ESG] won’t be as good or durable over time as with bariatric surgery, but ... we will have to see.”

However, “we know that, typically, combinations of therapeutic options work better than a one-off option, so I think the real benefit of this study – outside the specific procedure and this specific medication – is that it is a very valuable proof-of-principle study showing that combinations do work better,” Dr. Kahan said in an interview.
 

Minimally invasive endoscopic sleeve gastroplasty

ESG is a surrogate for laparoscopic sleeve gastrectomy that can offer the benefits of such a procedure to those who don’t qualify for, or don’t wish to pursue, bariatric surgery. It can be performed at an earlier stage of disease, in those with a body mass index of 30 mg/kg², whereas generally people are not offered bariatric procedures unless they have a BMI of at least 35 with comorbidities or a BMI of at least 40 if they do not have comorbidities.

Subcutaneous semaglutide is already approved for the treatment of type 2 diabetes in adults at doses of up to 1 mg/week; higher doses are needed for weight loss. Novo Nordisk has been investigating higher doses for weight loss in the STEP trial program, which is now complete, and the company has submitted the data to the Food and Drug Administration and European Medicines Agency for an additional indication of adults with obesity (BMI ≥30) or who are overweight (BMI ≥27) and who have at least one weight-related comorbidity, as an adjunct to a reduced-calorie diet and increased physical activity, with a decision expected soon.

Novo Nordisk has also developed an oral form of semaglutide, which has been approved as a once-daily agent for type 2 diabetes (Rybelsus) in doses of 7 mg and 14 mg to improve glycemic control along with diet and exercise. It is the first GLP-1 agonist available in tablet form.
 

Patients lost fat mass as well as excess weight

The Brazilian study involved 58 patients with obesity or overweight who also had diabetes and were undergoing minimally invasive ESG; they were further randomized to receive semaglutide or placebo.

The GLP-1 agonist (or sham placebo) was initiated 1 month after participants had undergone the procedure and patients were monitored each month for weight loss and type of fat loss achieved with the combination versus ESG alone. The initial dose of semaglutide used was 0.25 mg subcutaneous a week but could be titrated up to a maximum dose of 1.5 mg.

At the end of 11 months of active treatment versus placebo (12 months after ESG), patients who received additional semaglutide lost 86.3% of their excess body weight – the amount of weight patients needed to lose to reach normal BMI – compared with only 60.4% for ESG controls.

Due to the heterogeneity of outcomes and study designs, consensus on definitive prostate cancer risk assessment has been somewhat elusive. Differences in outcomes based on ethnicity and race have been observed, but much data on risk has originally been obtained in populations with lower ethnic and racial diversity, complicating extrapolation to larger populations. Huynh-Le et al developed an updated polygenic hazard score (PHS₂) based on a single nucleotide polymorphism (SNP) panel (46 total SNPs) for prostate cancer patients with multiple ethnicities (African, Asian, and European ancestries). This updated PHS₂ score stratified men into higher and lower risks for any, aggressive, and fatal prostate cancers in a statistically significant way. Camargo et al took a different approach and evaluated whether 2 SNPs were prognostic in prostate cancer: rs1834306 corresponding to microRNA 100 (miR 100) and rs2910164 from miR 146a. There were no differences in miR 100 or miR 156a between patients with local prostate cancer or a control group of men without prostate cancer. In addition, there were no differences in the chance of particular genotypes between the 2 groups. There was an association between lower presence of rs1834306 (miR 100) and patients with PSA > 10 mg/mL and between a higher amount of the polymorphic allele for rs2910164 (miR 146A).

The 3 studies summarized here demonstrate the ongoing challenges in how to identify nuances that will affect clinical decision-making in PSA screening and to identify prognostic features that associate with particular outcomes. The study by Bergengren confirmed the current state of PSA screening in that balancing diagnosis and potential overtreatment with modest survival outcomes is challenging. While the studies by Huynh-Le  et al and Camargo et al have interesting findings, the use of SNPs and miR in prostate cancer prognosis is still not ready for routine clinical use in prostate cancer management.
