A Trial Investigating the Pain-relieving Properties of Lu AG06474 in Healthy Adult Participants

Phase 1
Completed
Conditions
Healthy Participants
Interventions
Drug: Placebo to Lu AG06474
Drug: Placebo
Registration Number
NCT06077786
Lead Sponsor
H. Lundbeck A/S
Brief Summary

The main goal of this trial is to learn about the effect of Lu AG06474 on a battery of Evoked Pain Tests when a single dose is given to healthy adult participants. The effects of Lu AG06474 will be compared with 2 approved pain-relieving medications (ibuprofen and pregabalin) and with a placebo (a treatment that looks like the trial treatment but does not have any medicine in it). Each participant will receive 1 dose of each of these treatments during the trial (Lu AG06474, ibuprofen, pregabalin, and placebo), with 1 week between treatments. All treatments will be taken orally (by mouth), either as a liquid or a capsule.

Primary Outcome Measures
NameTimeMethod
Change From Baseline in Pain Detection Thresholds (PDTs) for the Capsaicin Heat Pain TestBaseline to 6 hours post-dose

The PDT is the degrees Celsius where the participant first detects pain.

Change From Baseline in Area of Secondary Mechanical Allodynia After the Capsaicin ChallengeBaseline to 6 hours post-dose

The area of secondary mechanical allodynia will be reported for the capsaicin challenge, measured in squared millimeters (mm\^2).

Change From Baseline in Pain Tolerance Thresholds (PTTs) for the Cold Pressor TestBaseline to 6 hours post-dose

The PTT is the timepoint (in seconds) where the participant can no longer tolerate the pain.

Change From Baseline in Pain Detection Thresholds (PDTs) for the UVB Heat Pain TestBaseline to 6 hours post-dose

The PDT is the degrees Celsius where the participant first detects pain.

Change From Baseline in Pain Detection Thresholds (PDTs) for the Cold Pressor TestBaseline to 6 hours post-dose

The PDT is the timepoint (in seconds) where the participant first detects the pain.
