A Trial Investigating the Pain-relieving Properties of Lu AG06474 in Healthy Adult Participants
Study Details
Study Description
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.

Outcome Measures
Primary Outcome Measures
- Change From Baseline in Pain Detection Thresholds (PDTs) for the UVB Heat Pain Test [Baseline 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 Capsaicin Heat Pain Test [Baseline 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 Challenge [Baseline 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 Test [Baseline 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 Cold Pressor Test [Baseline to 6 hours post-dose]
The PDT is the timepoint (in seconds) where the participant first detects the pain.
Secondary Outcome Measures
- AUC0-8h: Area Under the Curve Concentration-time Curve from Zero to 8 hours Post-dose [0 (predose) to 8 hours postdose on Day 1 to Day 22]
- Cmax: Maximum Observed Plasma Concentration [0 (predose) to 8 hours postdose on Day 1 to Day 22]
- tmax: Nominal Time Corresponding to the Occurrence of Cmax [0 (predose) to 8 hours postdose on Day 1 to Day 22]
- Difference to Placebo in Blood Levels of Endocannabinoids [0 (predose) to 8 hours postdose on Day 1 to Day 22]
Eligibility Criteria
Criteria
Inclusion Criteria:
-
The participant has a body mass index (BMI) ≥18.5 and ≤32 kilograms per meter squared (kg/m^2) at the Screening Visit and at the Trial Baseline Visit.

-
The participant has Fitzpatrick skin type IV, V and VI, wide-spread acne, tattoos, or scarring interfering with the area of interest (that is, upper back).
-
The participant is currently enrolled in another clinical trial or used any investigational drug or device within 3 months (or <5 half-lives of that product, whichever is longer) prior to dose of investigational medicinal product (IMP), or has participated in more than 4 investigational drug studies within 1 year prior to Screening.
-
The participant takes any disallowed medication within 14 days from first dose of trial drug.
-
The participant has been vaccinated ≤14 days prior to the first dose of IMP.
-
The participant is pregnant, breastfeeding, intends to become pregnant, or is of child bearing potential and not willing to use adequate contraceptive methods.
