Division Faculty Member Co-Authors Landmark Study Showing New Hope for Patients with Acquired Hypothalamic Obesity

Dr. Larson Ode

We are proud to recognize Dr. Larson Ode as a co-author of a groundbreaking clinical trial published last week in the New England Journal of Medicine. The study demonstrates the effectiveness of a novel treatment of acquired hypothalamic obesity, a rare and devastating condition that until now has lacked effective medical therapies. In the phase 3 trial, researchers evaluated setmelanotide in children and adults with hypothalamic obesity resulting from tumors, injuries, or other damage to the hypothalamic region of the brain. After 52 weeks of treatment, participants receiving setmelanotide experienced a 16.5% reduction in body mass index (BMI) on average, while those receiving placebo showed an increase in BMI. The findings represent an important breakthrough for patients and families affected by hypothalamic obesity, a condition that is notoriously difficult to treat because it disrupts the brain pathways that regulate appetite and energy balance. By targeting the key brain pathways involved, setmelanotide addresses the mechanisms underlying the disease rather than simply treating its symptoms. Published in one of the world’s leading medical journals, this study provides compelling evidence that setmelanotide may offer a much-needed therapeutic option for individuals living with acquired hypothalamic obesity. We congratulate Dr. Larson Ode and her co-authors on this significant achievement and on their contributions to advance care for patients with complex obesity disorders. The study’s abstract can be found at this PubMed link.

Concordance of HbA1c and CGM in Adults with Cystic Fibrosis–Related Diabetes

Dr. Larson Ode

A newly published manuscript examines the relationship between HbA1c and continuous glucose monitoring (CGM)–derived metrics in adults with cystic fibrosis–related diabetes (CFRD). This work addresses an ongoing clinical question in CFRD care, particularly in the era of widespread CGM use and modern CFTR modulator therapy. Drawing on real-world data from adults with established CFRD, the study demonstrates agreement between HbA1c and CGM-derived measures of mean glycemia, reinforcing clinical relevance of HbA1c while underscoring the added value of CGM metrics. Dr. Larson Ode from our division contributed to the manuscript, highlighting her ongoing commitment to advancing evidence-based care for people with cystic fibrosis and diabetes, and we congratulate her and the full author team on this meaningful contribution to the field.

Clinical Trial Shows Efficacy of a Once‑Weekly Growth Hormone Analog in Children With Noonan Syndrome

Dr. Tansey

A new multinational, phase 3 clinical trial published online ahead of print in the European Journal of Endocrinology studied the growth promoting effects of once‑weekly growth hormone analog versus standard daily growth hormone (GH) therapy for children living with Noonan syndrome. The results show that the weekly analog approach is superior to the daily approach in terms of enhancing growth rate. The study, titled “Once‑weekly Somapacitan in Children with Noonan Syndrome: Randomised Controlled Phase 3 Trial”. The trial authors included contributions from Dr. Tansey from our Division. A total of 77 children with Noonan syndrome were enrolled in the trial and randomized 2:1 to the once‑weekly standard or daily GH preparations over a one-year period. The children receiving the weekly analog grew a little faster (13% on average, statistically significant) compared with the daily GH group. Importantly, the weekly analog was well tolerated, showing a safety profile comparable to daily GH. It will be important to ascertain the long term impact of the weekly analog on final adult height in this population. These findings highlight a promising, less burdensome therapeutic option for families. We thank Dr. Tansey for his role in advancing this impactful work. The abstract of the work can be found at this pubmed link.

Safety of One Year’s Treatment with Inhaled Insulin in Children with Type 1 Diabetes

Dr. Tansey

Our division has contribution to a clinical study recently published in Diabetes Technology & Therapeutics : “Inhaled Technosphere Insulin in Children with Diabetes: The INHALE-1 Extension Study.” One of our Division physicians, Dr. Tansey, served as a co-author on this important research. This paper describes an extension phase to the INHALE-1 trial to better examine long-term safety of an inhaled form of insulin. The results from the first 26-week phase of trial were published several months ago. Inhaled insulin demonstrated similar glucose levels to conventional therapy with injected insulin but greater treatment satisfaction. The extension phase of the trial allowed participants the option to continue inhaled insulin for another 26 weeks to further evaluate safety. Even after one year’s treatment, there were no serious pulmonary complications among the participants. There was a small increase in hemoglobin A1c from week 26 to week 52 (from 8.2 to 8.6%). The manuscript abstract is available on Pubmed. The results show the potential safety of inhaled insulin for children with type 1 diabetes. We especially wish to thank the research coordinators, research participants and their families who made this study possible.

Muscle “Recycling Centers” Helps Prevent Type 2 Diabetes

Dr. Norris

A group of researchers have identified a key protein complex in muscle cells that regulates the body’s response to nutrients and helps maintain healthy blood sugar levels. The researchers focused on the role of this complex, known as LRRC8, in muscle lysosomes. Lysosomes are tiny compartments inside cells that act like recycling centers. The researchers found that lysosomal LRRC8 plays a critical role in governing cellular growth and metabolism. When LRRC8 was disrupted in lab-grown muscle cells, lysosomal function was impaired, weakening how muscle cells responded to nutrients and to insulin. Furthermore, mice lacking lysosomal LRRC8 developed increased body fat, insulin resistance, and poor glucose tolerance — conditions closely linked to type 2 diabetes. This research uncovers a previously unknown connection between LRRC8 lysosomal function in muscle cells and whole-body metabolic health, opening new avenues for understanding and potentially treating metabolic diseases such as type 2 diabetes. Dr. Norris from our division was part of the research team and is a co-author on the manuscript. The peer-reviewed findings are published in Science Advances under the title: “Lysosomal LRRC8 complex impacts lysosomal pH, morphology, and systemic glucose metabolism.” The abstract is available on PubMed: https://pubmed.ncbi.nlm.nih.gov/41004571/.

Advancing Expert Diagnosis and Care for Pancreatogenic Diabetes

Dr. Larson Ode
Dr. Norris

Pancreatogenic diabetes is an underrecognized form of diabetes that develops as a consequence of diseases affecting the exocrine pancreas. Though often overshadowed by type 1 and type 2 diabetes, pancreatogenic diabetes is estimated to account for 1–9% of all diabetes cases, making it a significant contributor to global health burden. This condition can arise from a range of pancreatic disorders, including pancreatitis, pancreatic cancer, cystic fibrosis, surgical removal of the pancreas, and fibrocalculous pancreatic disease. Each of these conditions presents unique diagnostic and therapeutic challenges, underscoring the need for heightened clinical awareness. Two faculty members from our Division, Dr. Larson Ode and Dr. Norris, have authored a comprehensive clinical review on this topic, recently accepted for publication in the Journal of Clinical Endocrinology and Metabolism (JCEM), one of the leading journals in the field.

Their article, titled “Approach to the Patient with Pancreatogenic Diabetes”, synthesizes current evidence and offers practical guidance for clinicians managing these complex cases. The work was co-authored by adult endocrinologist Dr. Yumi Imai. The review emphasizes the importance of timely diagnosis and tailored treatment. For instance, diabetes can be an early warning sign of pancreatic cancer—a disease with poor prognosis and no reliable biomarkers—making clinical suspicion critical. In cystic fibrosis, even mild diabetes can worsen lung function and increase mortality risk, highlighting the need for proactive screening. The authors also discuss the frequent coexistence of exocrine pancreatic insufficiency in these patients, noting that in these cases pancreatic enzyme replacement therapy may improve glycemic control.

We are glad that these authors have been able to bring their recognized expertise in pancreatogenic diabetes to this work, providing clinicians with actionable insights into evolving screening and treatment strategies. The article’s abstract can be found on PubMed (https://pubmed.ncbi.nlm.nih.gov/41252284/), where there are links to the open access full manuscript.

What Mechanisms Drive Diabetes-Risk in Youth with Pancreatitis?

Dr. Larson Ode
Dr. Catherina Pinnaro

Why does diabetes happen in some children who have experienced pancreatitis? A new study from Dr. Larson Ode and Dr. Pinnaro, along with a former research fellow Dr. Parra Villasmil, delves into this very question, uncovering unexpected patterns. Their work has been just published in the Journal of Pediatric Gastroenterology and Nutrition. The manuscript, titled “Early mechanisms of diabetes development in pediatric pancreatitis – a pilot study”, explores the complex interplay between pancreatitis and diabetes risk in children. Diabetes is a serious complication for children with pancreatitis, affecting nearly 9% during childhood and up to half over a lifetime. Despite this high risk, little is known about the underlying mechanisms or biomarkers that predict which children are most vulnerable. This study takes an important step toward filling that gap. Their findings revealed that 35% of participants exhibited dysglycemia, often linked to insulin resistance. Could insulin resistance be the key mechanism that drives diabetes risk? Another surprise finding was that dysglycemia was associated with higher pancreatic polypeptide levels. These results will help inform future studies that could pave the way for earlier detection and/or targeted interventions to prevent diabetes in this high-risk population.
