14 de septiembre de 2026 actualizado por: Ono Pharmaceutical Co., Ltd.

Estudio de fase 2, doble ciego, controlado con placebo, de grupos paralelos para evaluar la seguridad, la tolerabilidad, la farmacocinética, la farmacodinámica y la eficacia potencial de dosis múltiples de ONO-2808 en pacientes con atrofia multisistémica (MSA)

This is a Phase 2, double-blind, parallel-group, placebo-controlled study to assess the safety, tolerability, pharmacokinetics, pharmacodynamics, and efficacy of multiple doses of ONO-2808 in patients with MSA. This is the first study of ONO-2808 in patients with MSA.

Descripción detallada

This study will consist of a core part, an extension part, and an additional extension part. The purpose of the core part is to evaluate 3 doses of ONO-2808 compared to placebo in MSA patients, including: 1) safety and tolerability, 2) pharmacokinetics, and 3) changes in clinical outcome assessments (COA) and biomarkers considered to be related to the pharmacodynamics and potential efficacy of ONO-2808. The purpose of the extension part and the additional extension part is to evaluate 3 doses of ONO-2808 in MSA patients, including: 1) safety and tolerability and 2) changes in COAs and biomarkers considered to be related to the pharmacodynamics and potential efficacy of ONO-2808.

Descripción

Inclusion Criteria:

Exclusion Criteria:

  3. Neurological diseases/disorders other than MSA, such as Parkinson's disease, dementia with Lewy bodies, essential tremor, progressive supranuclear palsy, spinocerebellar ataxia, spastic paraparesis, corticobasal degeneration, or vascular, normal pressure hydrocephalus, pharmacological, or post-encephalitic parkinsonism.

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Incidence of Treatment-emergent Adverse Events (TEAEs) and Treatment-emergent Serious Adverse Events (TESAEs)
Periodo de tiempo: From screening up to follow-up for the core part (up to Week 28)

A TEAE was defined as any adverse event occurring or worsening on or after the first dose of study treatment. A TEAE was considered study treatment-related if there was a reasonable causal relationship between study intervention administration and the TEAE. A serious adverse event (SAE) was an event that resulted in death, was life-threatening, required hospitalization or prolongation of hospitalization, resulted in significant disability/incapacity, was a congenital anomaly/birth defect, or was considered an important medical event.
From screening up to follow-up for the core part (up to Week 28)
Incidence of TEAEs by Highest Severity
Periodo de tiempo: From screening up to follow-up for the core part (up to Week 28)

A TEAE was defined as any adverse event occurring or worsening on or after the first dose of study treatment.
From screening up to follow-up for the core part (up to Week 28)
Incidence of Study Treatment-related TEAEs by Highest Severity
Periodo de tiempo: From screening up to follow-up for the core part (up to Week 28)

A TEAE was defined as any adverse event occurring or worsening on or after the first dose of study treatment. A TEAE was considered study treatment-related if there was a reasonable causal relationship between study intervention administration and the TEAE.
