Safety Study of DS-5565 for Treatment of Fibromyalgia Pain in Subjects With Chronic Kidney Disease

A Randomized, Double-blind, Placebo-controlled Safety Study of DS-5565 for Treatment of Pain Due to Fibromyalgia in Subjects With Chronic Kidney Disease

DS-5565 (mirogabalin) is being studied as treatment for fibromyalgia (FM) pain. Because it is excreted through the kidneys, people who have reduced kidney function will not process the drug as well as with those with normal kidney function, so the dose must be reduced. This study will test two reduced dose levels for both moderately reduced and severely reduced kidney function. The study will test the hypothesis that the drug will be safe and well-tolerated in people who have both fibromyalgia and chronic kidney disease.

Study Overview

• Status: Completed
• Conditions: Fibromyalgia
• Intervention / Treatment: Drug: DS-5565; Drug: Placebo

Detailed Description

The main objective of the trial is to determine the safety and tolerability of subjects with FM and moderate to severe renal dysfunction during 13 weeks of renally-adjusted dosing of DS-5565 compared to placebo, followed by a short-term (4-week) safety follow-up.

This trial is conducted in accordance with the ethical principles of Good Clinical Practice, according to the International Council for Harmonisation (ICH) Harmonised Tripartite Guidelines. An independent Data Safety Monitoring Board (DSMB) is created to further protect the rights, safety, and well-being of subjects who participate in this study by monitoring their progress and results. The independent DSMB is composed of qualified scientists who are not investigators in the study and not otherwise directly associated with the sponsor.

Additional protection is provided by special monitoring of liver enzyme elevations and liver dysfunction performed by a Hepatic Adjudication Committee (HAC), comprised of three qualified hepatologists who are not investigators in the study and not otherwise directly associated with the sponsor. The HAC completes assessments on an ongoing basis. Adjudication of hepatic events is based on evaluation of electronic case report forms (eCRFs) and source documents, as available, including but not limited to hospital discharge summaries, diagnostic imaging, histopathology, consultation, and laboratory reports.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participants Experiencing a Treatment Emergent Adverse Event (TEAE)	A TEAE is any adverse event that emerges on or after the first dosing of double blind study medication and during study treatment up to 4 weeks after the last dose of double blind study medication (having been absent prior to treatment) or worsens relative to the pre-double blind treatment state. Relationship of TEAEs to study drug is assessed by the investigator. Clinically significant changes from baseline in clinical laboratory evaluations, neurological examinations, and electrocardiograms are reported as TEAEs.	Baseline up to 30 days after last dose, up to 25 months
Patients Answering Yes to Any Question on the Columbia-Suicide Severity Rating Scale (C-SSRS)	The C-SSRS is described as a scale developed at Columbia University that has 2-6 questions each in categories of Suicidal Ideation, Intensity of Ideation, Suicidal Behavior, and Actual Attempts. Four constructs were measured. Severity of Suicidal ideation is rated on a 5-point ordinal scale. Intensity of ideation is comprised of 5 items (frequency, duration, controllability, deterrents, and reason for ideation), each rated on a 5-point ordinal scale. Suicidal behavior is rated on a nominal scale that includes actual, aborted, and interrupted attempts; preparatory behavior; and non-suicidal self-injurious behavior. Lethality, assesses actual attempts; actual lethality is rated on a 6-point ordinal scale, and if actual lethality is 0, potential lethality of attempts is rated on a 3-point ordinal scale.The higher the C-SSRS score, the higher the suicide risk (ie. worse outcome).	Screening up to Week 13 postdose

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Mean Weekly Average of Individual Daily Pain Scores (ADPS)	Each day participants will rate their worst pain over the last 24 hours on a scale from 0-10, where 0=no pain and 10=worst pain imaginable. Each week individual pain scores will be averaged, and the mean weekly score for the treatment group will be calculated. Higher ADPS scores indicate worse outcome.	Baseline, Week 1, Week 2, Week 3, Week 4, Week 5, Week 6, Week 7, Week 8, Week 9, Week 10, Week 11, Week 12, and Week 13 postdose
Number of Participants With Different Scale Ranges of the Patient Global Impression of Change (PGIC) Scale at Week 13	The PGIC is a validated outcome measure for treatment of pain in the acute pain setting. At the end of treatment, participants will rate their overall status on a scale of 1-7, where 1=very much improved and 7=very much worse using the standard PGIC questionnaire. Higher scores indicate worse outcome.	Week 13 postdose
