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.

Conditions

Healthy Participants

Outcome Measures

Primary Outcomes (5)

• Change From Baseline in Pain Detection Thresholds (PDTs) for the UVB Heat Pain Test

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

  Baseline to 6 hours post-dose

• Change From Baseline in Pain Detection Thresholds (PDTs) for the Capsaicin Heat Pain Test

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

  Baseline to 6 hours post-dose

• Change From Baseline in Area of Secondary Mechanical Allodynia After the Capsaicin Challenge

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

  Baseline to 6 hours post-dose

• Change From Baseline in Pain Tolerance Thresholds (PTTs) for the Cold Pressor Test

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

  Baseline to 6 hours post-dose

• Change From Baseline in Pain Detection Thresholds (PDTs) for the Cold Pressor Test

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

  Baseline to 6 hours post-dose

Secondary Outcomes (4)

• 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

• Age: 18 Years - 55 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• 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.

You may not qualify if:

• The participant is a member of the site staff or of their immediate families or is a subordinate (or immediate family member of a subordinate) to any of the site staff.
• 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.
