New pain pill LTG-321 enters first human safety tests
NCT ID NCT07110610
First seen Jun 25, 2026 · Last updated Jun 30, 2026 · Updated 3 times
Summary
This early-stage study tests an experimental oral drug called LTG-321 in 236 healthy adults aged 18-55. The main goal is to check safety and how the body processes the drug. Researchers will also measure pain tolerance using a cold water test and see if a high-fat meal affects drug levels. This is a first step to see if LTG-321 is safe enough for future pain studies.

- What this could lead to
- If successful, this could pave the way for further studies of LTG-321 as a potential pain treatment.
- What could go wrong
- This is a very early Phase 1 trial in healthy people, not patients. It primarily tests safety, not effectiveness. The drug may not work or could have side effects.

Inclusion Criteria: * Male and female participants aged 18 to 55 years, inclusive, at the time of signing the informed consent. * Overtly healthy with no clinically relevant abnormalities based on the medical history, physical examinations, clinical laboratory evaluations, and 12-lead ECG that, in the opinion of the investigator, would affect participant safety. * Body mass index (BMI) within the range of 18-30 kg/m2 (inclusive). Exclusion Criteria: * Inability to take oral medications or gastrointestinal abnormalities potentially impacting absorption. * Clinically significant cardiovascular, hematological, renal, hepatic, pulmonary, endocrine, gastrointestinal, immunological, dermatological, neurological, or psychiatric disease which could interfere with, or the treatment for which might interfere with, the conduct of the study or which would, in the opinion of the investigator, unacceptably increase the participant's risk by participating in the study. * Past or current history or evidence of alcohol abuse and/or dependence on recreational drug use * Donation of over 500 mL blood ≤ 3 months prior to start of participation * Participant is under legal custodianship.
