Effekt, sikkerhet, tolerabilitet, farmakodynamikk og farmakokinetikk av BIA 28-6156 i GBA-PD (ACTIVATE)

5. november 2026 oppdatert av: Bial R&D Investments, S.A.

En fase 2, randomisert, dobbeltblind, placebokontrollert studie for å evaluere effektiviteten, sikkerheten, tolerabiliteten, farmakodynamikken og farmakokinetikken til BIA 28-6156 hos personer med Parkinsons sykdom med en patogen variant i glukocerebrosidase (GBA1)

The purpose of this randomized, double-blind, placebo-controlled study is to assess the efficacy of BIA 28-6156 over placebo in delaying clinical meaningful motor progression over 78 weeks in subjects with Parkinson's disease who have a pathogenic variant in the glucocerebrosidase 1 (GBA1) gene (GBA-PD).

Detaljert beskrivelse

This is a 2-part (Part A [Genetic Screening] and Part B [Double-Blind Treatment]), Phase 2, multicenter, randomized, double-blind, placebo-controlled study to evaluate the efficacy, safety, tolerability, pharmacodynamics, and pharmacokinetics of 2 fixed dose levels of BIA 28-6156 (10 and 60 mg/day) in approximately 237 subjects with genetically confirmed GBA-PD.

Part A (Genetic Screening) will identify individuals with a PD risk-associated variant in the GBA1 gene for potential enrolment into Part B (Double-Blind Treatment) of the study. Part B will consist of a screening period to ensure that all protocol inclusion/exclusion criteria for Part B of the study are met (up to 5 weeks). After screening period, eligible subjects will be randomized into 1 of 3 treatment arms (BIA 28-6156 10 mg/day, BIA 28-6156 60 mg/day, or placebo) in a 1:1:1 ratio, and enter a double-blind treatment period up to 78 weeks, followed by a 30-day (4 weeks) of safety follow-up period.

Subjects must be receiving a stable dose of PD medication for at least 30 days before screening (for Part B [Double-Blind Treatment]) and will continue to receive their usual PD medications throughout the study.

  • The subject has previously received BIA 28-6156 or has a known allergy or hypersensitivity to BIA 28-6156 or any components of the formulation.
  • The subject is an unsuitable candidate to receive BIA 28-6156 or is unable or unlikely to comply with the dosing schedule or study evaluations in the judgment of the investigator.

Tiltaksbeskrivelse
Tidsramme
Time from baseline to clinically meaningful progression on motor aspects of experiences of daily living (assessed by MDS-UPDRS Part II score and MDS-UPDRS Part III score)
Tidsramme: From Baseline up to Week 78

Time from baseline to clinically meaningful progression on motor aspects of experiences of daily living, as assessed by ≥2-point increase from baseline in Movement Disorder Society - Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part II score and no improvement in the Motor Examination, as assessed by ≥0-point increase from baseline in MDS-UPDRS Part III score. MDS-UPDRS is a multimodal scale assessing impairment and disability consisting of 4 parts. Part II assesses motor experiences of daily living (Range 0-52). It contains 13 questions which are to be rated by the patient and/or caregiver. Part III assesses the motor signs of PD and is rated by the investigator (Range 0-132). Part III contains 33 scores based on 18 items. For each question a numeric score is assigned between 0-4, where 0 = Normal, 1 = Slight, 2 = Mild, 3 = Moderate, 4 = Severe. A higher score indicates more severe symptoms of PD.

Tidsramme
Time from baseline to clinically meaningful progression on motor signs of the disease (assessed by MDS-UPDRS Part III score)
Tidsramme: From Baseline up to Week 78

Time from baseline to clinically meaningful progression on motor signs of the disease, as assessed by a ≥5-point increase from baseline in the MDS-UPDRS Part III score. MDS-UPDRS is a multimodal scale assessing impairment and disability consisting of 4 parts. Part III assesses the motor signs of PD and is rated by the investigator (Range 0-132). Part III contains 33 scores based on 18 items. A higher score indicates more severe symptoms of PD.
From Baseline up to Week 78
Time from baseline to any worsening on the Clinical Global Impression - Change (CGI-C) scale
Tidsramme: From Baseline up to Week 78

The Clinical Global Impression of Change (CGI-C) is a scale used to assess the overall clinical improvement or worsening of a patient's condition over time. The CGI-C scale ranges from 1 to 7, with lower scores indicating greater improvement (1 - Very much improved, 2 - Much improved, 3 - Minimally improved, 4 - No change, 5 - Minimally worse, 6 - Much worse, 7 - Very much worse).
From Baseline up to Week 78
Time from baseline to any worsening on the Patient Global Impression - Change (PGI-C) scale
Tidsramme: From Baseline up to Week 78

The Patient Global Impression of Change (PGI-C) is a self-report tool used to assess a patient's perception of their overall improvement or worsening in a particular health-related domain over time. The PGI-C scale asks patients to rate their overall improvement or worsening since the start of treatment on a seven-point scale, with lower scores indicating greater improvement (1 - Very much improved, 2 - Much improved, 3 - Minimally improved, 4 - No change, 5 - Minimally worse, 6 - Much worse, 7 - Very much worse)
From Baseline up to Week 78
Change from Baseline to Week 78 in the MDS-UPDRS Total (Part I-IV) score
Tidsramme: From Baseline up to Week 78

The MDS-UPDRS assesses nonmotor and motor experiences of daily living, motor examination, and motor complication categories. The MDS-UPDRS Part I-IV total score was calculated as the sum of the individual item scores from these categories. Each item is rated on a scale from 0 to 4 on which 0 = normal, 1 = slight, 2 = mild, 3 = moderate, and 4 = severe. A higher score indicates more severe symptoms of PD.
From Baseline up to Week 78
Change from Baseline to Week 78 in the Modified Hoehn and Yahr score
Tidsramme: From Baseline up to Week 78

The Modified Hoehn and Yahr scale measures the severity of Parkinson's disease by assessing the patient's motor symptoms and functional impairment. The scale has seven stages, ranging from 1 to 5, with higher scores indicating more severe disease. (1 - Unilateral involvement only; 1.5 - Unilateral and axial involvement; 2 - Bilateral involvement without impairment of balance; 2.5 - Mild bilateral disease with recovery on pull test; 3 - Mild to moderate bilateral disease; some postural instability; physically independent; 4 - Severe disability; still able to walk or stand unassisted; 5 - Wheelchair bound or bedridden unless added).
From Baseline up to Week 78
Change from Baseline to Week 78 in the 39-Item Parkinson's Disease Questionnaire (PDQ-39) score
Tidsramme: From Baseline up to Week 78

The PDQ-39 is the most thoroughly validated and extensively used self-report measure for the assessment of health-related quality of life in patients with PD. The questionnaire measures 39 items, which assess 8 domains of health: mobility (10 items), activities of daily living (6 items), emotional well being (6 items), stigma (4 items), social support (3 items), cognitions (4 items), communication (3 items), and bodily discomfort (3 items). Each item is scored on the following scale: 0 = never, 1 = occasionally, 2 = sometimes, 3 = often, and 4 = always. Items in each subscale and the total scale can be summarized into an index and transformed linearly to a scale from 0 (perfect health as assessed by the measure) to 100 (worst health as assessed by the measure).
