Tradipitant to be evaluated for reducing GLP-1R agonist-induced nausea and vomiting in overweight adults

A Study to Measure the Effects of Using Tradipitant on Nausea and Vomiting After GLP-1R Agonist Use

Background

Nausea and vomiting are common and often dose-limiting side effects associated with GLP-1 receptor agonist (GLP-1R) therapies, which are widely used for type 2 diabetes and obesity management. These gastrointestinal adverse events can significantly impact patient adherence and quality of life, leading many to discontinue treatment or avoid dose escalation. Current management strategies are often symptomatic and non-specific, highlighting a critical unmet need for targeted interventions that can improve tolerability and enable patients to achieve optimal therapeutic benefits from GLP-1R agonists. Tradipitant, an NK-1 receptor antagonist, offers a potential mechanism to address these symptoms.

Study Design

The Thetis Study is a Phase 3, randomized, double-blind, placebo-controlled clinical trial designed to evaluate Tradipitant's efficacy. Healthy overweight, class I, or class II obese volunteers will be enrolled. Participants will receive a GLP-1R agonist, followed by either Tradipitant or a placebo. The study features two distinct treatment arms, though specific dosing regimens for Tradipitant or the GLP-1R agonist, route of administration, frequency, or duration are not detailed in the abstract. The primary endpoint will focus on measuring the effects on nausea and vomiting.

Results

As this is an active, recruiting Phase 3 clinical trial (NCT07446439), no efficacy or safety results are currently available. The study's primary objective is to quantify the effect of Tradipitant on the incidence and severity of nausea and vomiting following GLP-1R agonist administration. This rigorous, placebo-controlled design aims to provide definitive data on whether Tradipitant can offer a significant clinical benefit in managing these common adverse effects. Secondary objectives will likely include assessments of tolerability, quality of life metrics, and potentially pharmacokinetic interactions, though these specific details are not provided in the abstract. The trial is designed to establish a clear profile for Tradipitant's utility in this context.

The study aims to determine if Tradipitant can significantly reduce GLP-1R agonist-induced nausea and vomiting in healthy overweight or obese individuals.

Key Findings

  • Primary objective: Measure the effects of Tradipitant on nausea and vomiting after GLP-1R agonist use.
  • Study is a Phase 3, randomized, double-blind, placebo-controlled trial.
  • Participants are healthy overweight, class I, or class II obese volunteers.
  • Features two treatment arms (Tradipitant vs. placebo) following GLP-1R agonist administration.

Why It Matters

If successful, this study could significantly improve the tolerability and adherence to GLP-1R agonist therapies, which are cornerstones in obesity and diabetes management. Tradipitant could become a crucial co-prescription, allowing more patients to reach and sustain higher, more effective doses of GLP-1R agonists without debilitating side effects. This would enable broader access to the full metabolic benefits of GLP-1R agonists, potentially leading to better weight loss and glycemic control outcomes. For peptide users and clinicians, a proven adjunct therapy would offer a practical solution to a widespread challenge, potentially changing current GLP-1R agonist titration protocols by mitigating early adverse events.
