New drug interaction study could shape future obesity treatments
NCT ID NCT07710729
First seen Jul 17, 2026 · Last updated Aug 26, 2026 · Updated 2 times
Summary
This study investigates whether an experimental drug called UBT251 changes how the body processes oral contraceptives and how quickly the stomach empties. It involves women who cannot become pregnant and have overweight or obesity. The goal is to understand if UBT251 can be safely taken with common medications like birth control pills.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- UBT251, an experimental drug, given alongside an oral contraceptive and acetaminophen
- What this could lead to
- If successful, this study could help determine whether UBT251 is safe to use with oral contraceptives, supporting its development as a potential treatment for overweight or obesity.
- What could go wrong
- This is an early-phase study with only 40 participants, so results may not apply to the broader population. The study focuses on drug interactions, not on weight loss or long-term safety.

Inclusion Criteria: * Female (sex assigned at birth) of NCBP. * Age 18-65 years (both inclusive) at the time of signing the informed consent. * Body mass index (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 compound containing glucagon-like peptide 1 (GLP-1), glucose-dependent insulinotropic polypeptide (GIP), or glucagon (GCG) receptor agonism within 90 days before screening. * Any contraindications for the use of the oral contraception used in the study according to the PORTIA Product Information. * Use of hormone replacement therapy within 28 days before screening or intention to initiate treatment with hormone replacement therapy during the study. * Use of prescription medicinal products or non-prescription drugs, including any herbal medicine known to interfere with the metabolic cytochrome P450 (CYP) pathways, such as perikon (St. John's Wort), 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 and acetylsalicylic acid, or topical medication not reaching systemic circulation. * 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.
