Efficacy and Safety of Mirogabalin in Uremic Pruritus
Efficacy and Safety of Mirogabalin for Uremic Pruritus in Hemodialysis Patients: A Randomized Controlled Trial
This study aims to assess the efficacy and safety of mirogabalin in alleviating moderate-to-severe uremic pruritus in patients undergoing maintenance hemodialysis, and to establish the optimal dosing frequency by comparing continuous daily administration against intermittent post-dialysis administration.

Detaljeret beskrivelse
Uremic pruritus is a prevalent and distressing condition affecting over 60% of patients undergoing hemodialysis, with 20% to 40% experiencing moderate-to-severe symptoms. This condition is strongly associated with poor sleep architecture, depression, diminished quality of life, and an increased risk of mortality. The exact pathogenesis is multifactorial, involving metabolic disturbances, dysregulated immune responses, imbalances in the endogenous opioid system, and peripheral neuropathy.
While current off-label therapies for uremic pruritus include gabapentinoids targeting neuropathic mechanisms, their clinical utility in end-stage renal disease (ESRD) is severely limited by dose-dependent central nervous system (CNS) toxicity, particularly somnolence and dizziness. Mirogabalin is a novel, preferentially selective α2δ - 1 ligand hypothesized to provide robust anti-pruritic efficacy with a significantly lower incidence of neurotoxicity. Because mirogabalin is primarily eliminated by the kidneys, this trial will evaluate the efficacy, safety, and optimal dosing frequency (daily versus post-dialysis intermittent dosing) to prevent drug accumulation in the hemodialysis population.

|
Change in Uremic Pruritus Intensity
Tidsramme: Baseline to Week 12
|
The mean change in uremic pruritus intensity will be measured by two tools: the Visual Analogue Scale (VAS) and the 5-D itch scale. The VAS ranges from 0 (no pruritus) to 10 (worst possible itching). The 5-D itch scale ranges from 5 to 25, with higher scores reflecting worse pruritus severity. |

Percentage of Participants Achieving a Clinically Significant Reduction in Pruritus Severity
Tidsramme: Baseline and Week 12
|
Pruritus severity will be assessed using the Visual Analogue Scale (VAS), which ranges from 0 (no pruritus) to 10 (worst possible itching). A clinically significant reduction is defined as a shift in severity grade, such as moving from severe/very severe ($\ge 7$) to mild/moderate (<7). |
Baseline and Week 12

Incidence and Severity of Treatment-Emergent Adverse Events (TEAEs)
Tidsramme: Up to Week 12
|
Safety and tolerability will be evaluated and compared between the intermittent and daily mirogabalin arms. This measure will track the number of participants experiencing central nervous system adverse events (e.g., dizziness, somnolence, confusion) and gastrointestinal events (e.g., diarrhea, vomiting), along with the clinical grading of their severity. |
Up to Week 12
