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 mean

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

Active substance
LTG-321 (oral drug)
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).
