A Study to Evaluate Lu AG06466 in Participants With Fibromyalgia

Phase 1

Terminated

• Conditions: Fibromyalgia
• Interventions: Drug: Placebo; Drug: Lu AG06466

• Registration Number: NCT04974359
• Lead Sponsor: H. Lundbeck A/S

Brief Summary

The purpose of this study is to find out the effect of Lu AG06466 on the body in participants with fibromyalgia by assessing pain levels, brain signal changes, and psychiatric (mental) assessments.

Detailed Description

This study will include 2 treatment periods and will utilize a crossover study design with a 7- to 14-day washout period between each 22-day treatment period.

Recruitment & Eligibility

• Status: TERMINATED
• Sex: Female
• Target Recruitment: 3

Inclusion Criteria

• The participant has a body mass index (BMI) of ≥18.5 and ≤38.0 kilograms (kg)/square meter (m^2).
• The participant has a fibromyalgia diagnosis, with self-reported pain visual analogue scale (VAS) score >4, based on a self-reported pain diary assessed for a minimum of 4 out of 7 days prior to the Baseline Visit.
• The participant is, in the opinion of the investigator, eligible based on medical history, a physical examination, a neurological examination, vital signs (including orthostatic vital signs), an electrocardiogram (ECG), and the results of the clinical chemistry, hematology, urinalysis, serology, and other laboratory tests.

Exclusion Criteria

• The participant has a disease, including clinically significant liver disease of any origin, or takes medication that could, in the investigator's opinion, interfere with the assessments of safety, tolerability, or efficacy, or interfere with the conduct or interpretation of the study.
• The participant has any other disorder for which the treatment takes priority over the treatment of fibromyalgia in this study or is likely to interfere with the study treatment or impair treatment compliance.

Other inclusion and exclusion criteria may apply.

Arm && Interventions

Group	Intervention	Description
Placebo	Placebo	Participants will receive an oral dose of placebo matching to Lu AG06466 once daily for 22 days in 1 of 2 treatment periods.
Lu AG06466	Lu AG06466	Participants will receive an oral titrated dose of Lu AG06466 once daily for 22 days in 1 of 2 treatment periods.

Primary Outcome Measures

Name	Time	Method
fMRI Data: BOLD Percent Signal Change Under Conditions of Visual Stimulation Versus Fixation	Day 22 of each 22-day treatment period	Each participant will undergo a block design scan, with alternating blocks of flashing checkerboard and a static fixation cross.
Blood Oxygene Level Dependent (BOLD) Response in the Evoked-Pain Test	Day 22 of each 22-day treatment period	BOLD response was evaluated using Functional Magnetic Resonance Imaging (fMRI). During the evoked-pain test, each participant will undergo a block design scan, during which 3 cuff pressures ('light touch' = 30 millimeter of mercury \[mmHg\]; 'equal pressure' = 120 mmHg; 'equal pain' = 40 to 60/100 Numeric Rating Scale \[NRS\] units) will be applied to the left calf using the pressure cuff device in pseudo random order.
Change in Resting State fMRI (rsfMRI) Functional Connectivity, Assessed by Voxelwise Connectivity Maps Based in Seed Voxels	Day 22 of each 22-day treatment period	Each participant will undergo a task-free resting state scan, where in they will be instructed to focus on a static fixation cross.
