A new drug currently known as NG101 reduced nausea and vomiting in patients with obesity using GLP-1s by 40% and 67%, respectively, based on data from a phase 2 trial presented at the Obesity Society’s Obesity Week 2025 in Atlanta.

Previous research published in JAMA Network Open showed a nearly 65% discontinuation rate for three GLP-1s (liraglutide, semaglutide, or tirzepatide) among adults with overweight or obesity and without type 2 diabetes. Gastrointestinal (GI) side effects topped the list of reasons for dropping the medications.

Given the impact of nausea and vomiting on discontinuation, there is an unmet need for therapies to manage GI symptoms, said Kimberley Cummings, PhD, of Neurogastrx, Inc., in her presentation.

In the new study, Cummings and colleagues randomly assigned 90 adults aged 18-55 years with overweight or obesity (defined as a BMI ranging from 22.0 to 35.0) to receive a single subcutaneous dose of semaglutide (0.5 mg) plus 5 days of NG101 at 20 mg twice daily, or a placebo.

NG101 is a peripherally acting D2 antagonist designed to reduce nausea and vomiting associated with GLP-1 use, Cummings said. NG101 targets the nausea center of the brain but is peripherally restricted to prevent central nervous system side effects, she explained.

Compared with placebo, NG101 significantly reduced the incidence of nausea and vomiting by 40% and 67%, respectively. Use of NG101 also was associated with a significant reduction in the duration of nausea and vomiting; GI events lasting longer than 1 day were reported in 22% and 51% of the NG101 patients and placebo patients, respectively.

In addition, participants who received NG101 reported a 70% decrease in nausea severity from baseline.

Overall, patients in the NG101 group also reported significantly fewer adverse events than those in the placebo group (74 vs 135), suggesting an improved safety profile when semaglutide is administered in conjunction with NG101, the researchers noted. No serious adverse events related to the study drug were reported in either group.

The findings were limited by several factors including the relatively small sample size. Additional research is needed with other GLP-1 agonists in larger populations with longer follow-up periods, Cummings said. However, the results suggest that NG101 was safe and effectively improved side effects associated with GLP-1 agonists.

“We know there are receptors for GLP-1 in the area postrema (nausea center of the brain), and that NG101 works on this area to reduce nausea and vomiting, so the study findings were not unexpected,” said Jim O’Mara, president and CEO of Neurogastrx, in an interview.

The study was a single-dose study designed to show proof of concept, and future studies would involve treating patients going through the recommended titration schedule for their GLP-1s, O’Mara said. However, NG101 offers an opportunity to keep more patients on GLP-1 therapy and help them reach their long-term therapeutic goals, he said.
 

Decrease Side Effects for Weight-Loss Success

“GI side effects are often the rate-limiting step in implementing an effective medication that patients want to take but may not be able to tolerate,” Sean Wharton, MD, PharmD, medical director of the Wharton Medical Clinic for Weight and Diabetes Management, Burlington, Ontario, Canada, said in an interview. “If we can decrease side effects, these medications could improve patients’ lives,” said Wharton, who was not involved in the study.

The improvement after a single dose of NG101 in patients receiving a single dose of semaglutide was impressive and in keeping with the mechanism of the drug action, said Wharton. “I was not surprised by the result but pleased that this single dose was shown to reduce the overall incidence of nausea and vomiting, the duration of nausea, the severity of nausea as rated by the study participants compared to placebo,” he said.

Ultimately, the clinical implications for NG101 are improved patient tolerance for GLP-1s and the ability to titrate and stay on them long term, incurring greater cardiometabolic benefit, Wharton told GI & Hepatology News.

The current trial was limited to GLP1-1s on the market; newer medications may have fewer side effects, Wharton noted. “In clinical practice, patients often decrease the medication or titrate slower, and this could be the comparator,” he added.

The study was funded by Neurogastrx.

Wharton disclosed serving as a consultant for Neurogastrx but not as an investigator on the current study. He also reported having disclosed research on various GLP-1 medications.

Accurate neoplasia detection in patients with Barrett’s esophagus (BE) involves high-quality endoscopy, adequate biopsy sampling, careful examination, and appropriate recognition of neoplastic lesions, said Prateek Sharma, MD, in a presentation on the management of BE at the American College of Gastroenterology (ACG) 2025 Annual Scientific Meeting.

However, clinicians often make mistakes such as failing to remove debris such as saliva and bile from the esophagus prior to assessing a patient, said Sharma, professor of medicine and the Elaine Blaylock Endowed Professor at the University of Kansas School of Medicine and the Cancer Center, Kansas City, Kansas.

More than 90% of neoplasias in patients with BE are found on an index endoscopy or within 6 months, as shown by Sharma and his colleagues in a systematic review, which highlights the importance of a high-quality index endoscopy, he told meeting attendees.

To improve the index endoscopy, Sharma developed a new algorithm called “CLEAN.”

The algorithm is composed of five steps, he said, the first of which is Clear: clear the esophagus of debris, including saliva and bile. Adequate prep is essential to detecting clinically significant lesions in patients with BE, he explained. In a study published in 2024, Sharma and colleagues found adequate cleanliness of the upper gastrointestinal tract was associated with a significantly higher detection rate of clinically significant lesions.

The second step of the algorithm is Learn: pay attention to BE inspection time and learn slow withdrawal strategies.

It’s important not to shortchange inspection time, Sharma emphasized. He cited a previous study in which the percentage of patients with BE who had high-grade dysplasia or esophageal adenocarcinoma during a surveillance endoscopy was 15% with inspection times of 2 minutes or less but jumped to 69% with inspection times of 7 minutes or more.

The third step of CLEAN is Endoscope: conduct a high-definition white-light endoscopy, which should be coupled with the fourth step, Acquire: acquire education on BE-related neoplasia, to learn how to recognize neoplastic lesions, he stressed.

The final step of the algorithm is Neoplasia detection rate (NDR): follow a quality metric to measure NDR.

The algorithm emphasizes a comprehensive approach in conjunction with resection of visible lesions followed by ablation for complete eradication, Sharma told GI & Hepatology News.
 

After Identification: What’s Next?

If lesions are identified, the next step is resection and/or ablation, Sharma said.

“Resection is typically used for visible lesions, nodules, or masses, while ablation is used to treat the remaining underlying Barrett tissue,” he told GI & Hepatology News. “A combination of both is often necessary to fully treat advanced cases, such as when a nodule is resected and the surrounding area is subsequently ablated.”

“It’s important to understand why we need to resect,” he said.

“Resection removes the lesion” and “provides more accurate histopathology reading and staging of how deep the lesion is,” he explained. Options for resection of cancerous or precancerous lesions in patients with BE include endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD).

The treatment algorithm for BE continues to evolve, Sharma said in his presentation. Currently, evidence supports EMR for most cases, but ESD is based on factors including lesion size ≥ 25-30 mm and potential submucosal invasion, he said.

He cited a study of 1000 adults with early BE who were managed with EMR that showed a 96% curative response after 5 years. Similarly, a review of ESD for early BE neoplasia including 501 patients showed a 75% curative response rate overall and a 93% en bloc resection rate, he noted.
 

Ablation

In terms of ablation, radiofrequency ablation, hybrid argon plasma coagulation, and the multifocal cryoballoon procedure have shown significant effectiveness, Sharma said.

In a 2020 multicenter, prospective study of 120 adult patients with BE, 76% achieved complete eradication of dysplasia, and 72% achieved complete eradication of intestinal metaplasia. As for safety, data from nine European centers including 154 patients who underwent ablation after resection had an adverse event rate of 6%, said Sharma.
 

In the Clinic

“It is sometimes difficult to detect subtle nodularity and irregularity that would benefit more from resection therapy/EMR rather than ablation,” said Gyanprakash A. Ketwaroo, MD, associate professor of medicine (digestive diseases) at Yale University, New Haven, Connecticut.

“Lesions can be obscured by esophagitis, peristalsis, or the shape of the [gastroesophageal] GE junction,” he noted. Therefore, careful scope cleaning and inspection with high-definition white light and narrow band imaging are important, he said. “Using a cap on the scope to better distend or manipulate the gastroesophageal junction also helps identify obscured lesions,” he added.

“Any acronym or approach that reminds us to slow down, and examine carefully, is welcome,” Ketwaroo told GI & Hepatology News. The CLEAN algorithm provides a useful summary of some of the key steps all clinicians should incorporate into approaching BE and could be useful for teaching trainees, he added.

Accurate neoplasia detection in patients with Barrett’s esophagus (BE) involves high-quality endoscopy, adequate biopsy sampling, careful examination, and appropriate recognition of neoplastic lesions, said Prateek Sharma, MD, in a presentation on the management of BE at the American College of Gastroenterology (ACG) 2025 Annual Scientific Meeting.

However, clinicians often make mistakes such as failing to remove debris such as saliva and bile from the esophagus prior to assessing a patient, said Sharma, professor of medicine and the Elaine Blaylock Endowed Professor at the University of Kansas School of Medicine and the Cancer Center, Kansas City, Kansas.

More than 90% of neoplasias in patients with BE are found on an index endoscopy or within 6 months, as shown by Sharma and his colleagues in a systematic review, which highlights the importance of a high-quality index endoscopy, he told meeting attendees.

To improve the index endoscopy, Sharma developed a new algorithm called “CLEAN.”

The algorithm is composed of five steps, he said, the first of which is Clear: clear the esophagus of debris, including saliva and bile. Adequate prep is essential to detecting clinically significant lesions in patients with BE, he explained. In a study published in 2024, Sharma and colleagues found adequate cleanliness of the upper gastrointestinal tract was associated with a significantly higher detection rate of clinically significant lesions.

The second step of the algorithm is Learn: pay attention to BE inspection time and learn slow withdrawal strategies.

It’s important not to shortchange inspection time, Sharma emphasized. He cited a previous study in which the percentage of patients with BE who had high-grade dysplasia or esophageal adenocarcinoma during a surveillance endoscopy was 15% with inspection times of 2 minutes or less but jumped to 69% with inspection times of 7 minutes or more.

The third step of CLEAN is Endoscope: conduct a high-definition white-light endoscopy, which should be coupled with the fourth step, Acquire: acquire education on BE-related neoplasia, to learn how to recognize neoplastic lesions, he stressed.

The final step of the algorithm is Neoplasia detection rate (NDR): follow a quality metric to measure NDR.

The algorithm emphasizes a comprehensive approach in conjunction with resection of visible lesions followed by ablation for complete eradication, Sharma told GI & Hepatology News.
 

After Identification: What’s Next?

If lesions are identified, the next step is resection and/or ablation, Sharma said.

“Resection is typically used for visible lesions, nodules, or masses, while ablation is used to treat the remaining underlying Barrett tissue,” he told GI & Hepatology News. “A combination of both is often necessary to fully treat advanced cases, such as when a nodule is resected and the surrounding area is subsequently ablated.”

“It’s important to understand why we need to resect,” he said.

“Resection removes the lesion” and “provides more accurate histopathology reading and staging of how deep the lesion is,” he explained. Options for resection of cancerous or precancerous lesions in patients with BE include endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD).

The treatment algorithm for BE continues to evolve, Sharma said in his presentation. Currently, evidence supports EMR for most cases, but ESD is based on factors including lesion size ≥ 25-30 mm and potential submucosal invasion, he said.

He cited a study of 1000 adults with early BE who were managed with EMR that showed a 96% curative response after 5 years. Similarly, a review of ESD for early BE neoplasia including 501 patients showed a 75% curative response rate overall and a 93% en bloc resection rate, he noted.
 

Ablation

In terms of ablation, radiofrequency ablation, hybrid argon plasma coagulation, and the multifocal cryoballoon procedure have shown significant effectiveness, Sharma said.

In a 2020 multicenter, prospective study of 120 adult patients with BE, 76% achieved complete eradication of dysplasia, and 72% achieved complete eradication of intestinal metaplasia. As for safety, data from nine European centers including 154 patients who underwent ablation after resection had an adverse event rate of 6%, said Sharma.
 

In the Clinic

“It is sometimes difficult to detect subtle nodularity and irregularity that would benefit more from resection therapy/EMR rather than ablation,” said Gyanprakash A. Ketwaroo, MD, associate professor of medicine (digestive diseases) at Yale University, New Haven, Connecticut.

“Lesions can be obscured by esophagitis, peristalsis, or the shape of the [gastroesophageal] GE junction,” he noted. Therefore, careful scope cleaning and inspection with high-definition white light and narrow band imaging are important, he said. “Using a cap on the scope to better distend or manipulate the gastroesophageal junction also helps identify obscured lesions,” he added.

“Any acronym or approach that reminds us to slow down, and examine carefully, is welcome,” Ketwaroo told GI & Hepatology News. The CLEAN algorithm provides a useful summary of some of the key steps all clinicians should incorporate into approaching BE and could be useful for teaching trainees, he added.

Dear Friends,

Since moving to Missouri a little over 2 years ago, I got involved with the Missouri GI Society. They held their inaugural in-person meeting in September, and it was exciting to see and meet gastroenterologists and associates from all over the state. The meeting sparked conversations about challenges in practices and ways to improve patient care. It was incredibly inspiring to see the beginnings and bright future of a society motivated to mobilize change in the community. On a national scale, AGA Advocacy Day 2025 this fall was another example of how to make an impact for the field. I am grateful that local and national GI communities can be a platform for our voices.

In this issue’s “In Focus,” Dr. Colleen R. Kelly discusses the approach for weight management for the gastroenterologist, including how to discuss lifestyle modifications, anti-obesity medications, endoscopic therapies, and bariatric surgeries. In the “Short Clinical Review,” Dr. Ekta Gupta, Dr. Carol Burke, and Dr. Carole Macaron review available non-invasive blood and stool tests for colorectal cancer screening, including guidelines recommendations and evidence supporting each modality.

In the “Early Career” section, Dr. Mayada Ismail shares her personal journey in making the difficult decision of leaving her first job as an early career gastroenterologist, outlining the challenges and lessons learned along the way.

Dr. Alicia Muratore, Dr. Emily V. Wechsler, and Dr. Eric D. Shah provide a practical guide to tech and device development in the “Finance/Legal” section of this issue, outlining everything from intellectual property ownership to building the right team, and selecting the right incubator.

If you are interested in contributing or have ideas for future TNG topics, please contact me ([email protected]) or Danielle Kiefer ([email protected]), Communications/Managing Editor of TNG.

 

Until next time, I leave you with a historical fun fact because we would not be where we are now without appreciating where we were: screening colonoscopy for colorectal cancer was only first introduced in the mid-1990s with Medicare coverage for high-risk individuals starting in 1998, followed by coverage for average-risk patients in 2001.

Yours truly,
