Diabetes Dialogue: Insights on INHALE-1 and CATALYST Trials

, hosts Diana Isaacs, PharmD, an endocrine clinical pharmacist, director of Education and Training in Diabetes Technology, and codirector of Endocrine Disorders in Pregnancy at the Cleveland Clinic, and Natalie Bellini, DNP, program director of Diabetes Technology at University Hospitals Diabetes and Metabolic Care Center explore the increasing focus on the connection between 

, including the latest advancements in glucagon-like peptide-1 (GLP-1) receptor agonist therapies, the use of inhaled insulin, and the recent addition of hypercortisolism to the “Ominous Octet”, creating the “Noxious Nine.”

Although obesity rates in the US have been rising steadily globally, hosts pointed to a recent CDC report reporting a slight decrease in obesity rates. They suggest that this may be partially attributed to the impact of GLP-1 drugs, which have become increasingly popular in managing obesity and related metabolic disorders, including type 2 diabetes (T2D). With these drugs continuing to show promising results, the hosts express optimism about their potential to reduce obesity and improve long-term patient health outcomes.

Their conversation shifted to a detailed discussion of the INHALE-1 trial, which evaluated the effectiveness of inhaled insulin in children with type 1 diabetes (T1D) and T2D. The trial, designed to evaluate the non-inferiority of inhaled insulin compared to traditional subcutaneous injections, found that inhaled insulin provided similar efficacy without significant differences in lung function or hypoglycemia occurrence. Isaacs and Bellini highlighted the implications of these findings, emphasizing that inhaled insulin could offer an alternative treatment option for pediatric patients, particularly those who struggle with needle phobia or the burden of multiple daily injections (MDIs).

The episode concluded with a deep dive into the Catalyst study, which explored the use of mifepristone in patients with T2D complicated by hypercortisolism. The second phase of the Catalyst trial found a significant reduction in HbA1C levels, showing a 1.5% decrease in patients treated with mifepristone compared with the placebo group. Isaacs and Bellini discussed the potential clinical applications of these results, particularly for patients with difficult-to-control diabetes who may have an underlying hormonal issue contributing to their condition. Overall, hosts encouraged clinicians to consider hypercortisolism in their differential diagnosis for patients with challenging diabetes cases, noting the promise that mifepristone could offer as an adjunctive treatment.

Diabetes Dialogue: Exploring New Horizons in Incretin Therapy for Diabetes and Weight Loss

Diabetes Dialogue: Technology, Therapeutics, & Real-World Perspectives

, hosts Diana Isaacs, PharmD, an endocrine clinical pharmacist, director of Education and Training in Diabetes Technology, and codirector of Endocrine Disorders in Pregnancy at the Cleveland Clinic, and Natalie Bellini, DNP, program director of Diabetes Technology at University Hospitals Diabetes and Metabolic Care Center, explore recent advancements in incretin-based therapies, highlighting their transformative potential for 

The episode opens with a detailed discussion on Amgen’s maridebart cafraglutide (MariTide; AMG-133), an investigational antibody peptide conjugate offering remarkable efficacy for obesity and overweight in Phase 2 trial data. At 52 weeks, participants without type 2 diabetes (T2D) experienced an average weight loss of ~20% with MariTide treatment without a weight loss plateau, while those with T2D achieved up to a ~17% average reduction without a plateau. The hosts underscored the potential impact of this type of therapy, particularly in addressing adherence challenges posed by the more frequent dosing schedules of current options. Hosts cited the potential safety concerns, but noted that AMG-133 could represent a significant step forward in managing obesity and related metabolic disorders.

The conversation then shifted to a head-to-head comparison of two leading incretin therapies for obesity: tirzepatide (Zepbound) and semaglutide (Wegovy). Tirzepatide emerged as a frontrunner in the SURMOUNT-5 trial, contributing to a mean body weight reduction of 20.2% versus 13.7% achieved with semaglutide. Isaacs and Bellini discuss how these findings might influence clinical decision-making, emphasizing the importance of tailoring treatment plans to individual patient needs. They also touch on the practical implications of these therapies in both obesity and diabetes care, given the growing prevalence of these conditions.

In the final segment, Isaacs and Bellini addressed a critical safety issue: the proliferation of non-FDA-approved compounded glucgaon-like peptide-1 (GLP-1) receptor agonists. The American Diabetes Association (ADA) released a statement warning against these unregulated formulations due to concerns over safety, quality control, and potential adverse effects. Despite the growing popularity of compounded versions as a lower-cost alternative, the hosts stressed the importance of prioritizing patient safety. They advised clinicians to steer patients toward evidence-based, FDA-approved therapies that have undergone rigorous testing and demonstrated consistent efficacy and safety profiles.

Relevant disclosures for Isaacs include Eli Lilly and Company, Novo Nordisk, Sanofi, Abbott Diabetes Care, Dexcom, Medtronic, and others. Relevant disclosures for Bellini include Abbott Diabetes Care, MannKind, Provention Bio, and others.

In this episode, hosts discuss the efficacy of MariTide for obesity, a head-to-head comparison of semaglutide vs. tirzepatide, and concerns about GLP-1 agonist compounding.

Diabetes Dialogue: Celebrating 2024 - The Year of the Continuous Glucose Monitor

Diabetes Dialogue: Technology, Therapeutics, and Real-World Perspectives

, hosted by Diana Isaacs, PharmD, an endocrine clinical pharmacist, director of Education and Training in Diabetes Technology, and codirector of Endocrine Disorders in Pregnancy at the Cleveland Clinic, and Natalie Bellini, DNP, program director of Diabetes Technology at University Hospitals Diabetes and Metabolic Care Center.

, this episode recaps headlines and practice updates related to continuous glucose monitoring (CGM) from the past year, with a focus on regulatory news from Medtronic, Dexcom, Abbott, and Senseonics. In recognition of the 25th anniversary of the first US Food and Drug Administration (FDA) approval of a CGM device in 1999, hosts also provide historic context for each company spotlighted during the episode.

To begin the episode, hosts start where the journey began: the FDA approval of the MiniMed in June 1999. In the 25 years since, MiniMed was acquired by Medtronic but has continued to remain among the leaders in CGM technology. During their conversation, hosts spend time discussing early experiences with CGM as well as newer advances from Medtronic, including the 2024 approval of the Simplera CGM.

Conversation around Dexcom ranges from the company’s STS sensor in 2006 to the current G7 model as well as integration with pumps like the OmniPod 5, T:slim X2, and the Islet. When discussing news from 2024 from Dexcom, hosts call attention to the partnership with the Oura Ring and the launch of Stelo, the first FDA-approved over-the-counter CGM.

Next, hosts dive into advancements from Abbott—starting with the Navigator and advancing to the Libre, including the Libre 3 plus, which features real-time data and 15-day wear. The hosts also celebrate Abbott’s collaborations with Tidepool and major insulin pump manufacturers as well as the FDA clearance of the Lingo and Libre Rio.

The episode concludes with a discussion of Senseonics’ Eversense CGM, the only FDA-approved implantable CGM. As the hosts highlight, Eversense has progressed over the years from a 90-day sensor to the groundbreaking 365-day wear system, which received approval in 2024. The hosts also highlight the potential of future developments, such as eliminating the external transmitter for a fully implantable design.

In this episode, hosts reflect on the advancement in CGM that reshaped care for diabetes and overall health during 2024.
