Summary

This study investigates whether UBT251, an experimental drug for overweight or obesity, changes how the body processes other medications like warfarin, caffeine, and midazolam. Researchers will give UBT251 to 44 adults with a BMI between 27 and 39.9, then measure levels of these other drugs in the blood. The goal is to ensure UBT251 can be safely combined with common medicines without causing harmful interactions.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
UBT251 and a cocktail of warfarin, caffeine, and midazolam
What this could lead to
If successful, this could show that UBT251 is safe to use alongside common medications, paving the way for broader obesity treatments.
What could go wrong
This is an early-phase study with only 44 participants, so results may not apply to everyone. Drug interactions could still occur in real-world use.

Inclusion Criteria: * Male or female (sex assigned at birth, inclusive of all gender identities). * Age 18-65 years (both inclusive) at the time of signing the informed consent. * BMI between 27.0-39.9 kg/m\^2 (both inclusive) at screening. Overweight should be due to excess adipose tissue, as judged by the investigator. * Body weight \>=60.0 kg. * Considered to be generally healthy, except for overweight or obesity, based on the medical history, physical examination, and the results of vital signs, electrocardiogram and clinical laboratory tests performed during the screening visit, as judged by the investigator. Exclusion Criteria: * Known or suspected hypersensitivity to study intervention(s) or related products. * Treatment with any marketed product containing compounds with glucagon-like peptide 1 (GLP-1), glucose-dependent insulinotropic polypeptide (GIP), or glucagon (GCG) receptor agonism within 90 days before screening. * Use of prescription medicinal products or non-prescription drugs, including any herbal medicine known to interfere with the metabolic CYP pathways, such as perikon (St. John's Wort), ginseng, garlic, milk thistle, and echinaceae, within 14 days (or within 5 half-lives of the medicinal product, whichever is longest) of screening, with the exception of use of routine vitamins (vitamins used within a normal dose reference interval), occasional use of acetaminophen, ibuprofen, or topical medication not reaching systemic circulation. * Any contraindications for the use of caffeine, midazolam, and warfarin used in the study according to Vivarin®, Midazolam®, and warfarin sodium product information. * Presence of clinically significant gastrointestinal disorders or symptoms of gastrointestinal disorders potentially affecting absorption of drugs or nutrients, or as judged by the investigator. * History of major surgical procedures involving the stomach potentially affecting absorption of trial products (e.g. subtotal and total gastrectomy, sleeve gastrectomy, gastric bypass surgery) or current presence of gastrointestinal implant.
