NCT05819359

Brief Summary

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).

Outcome Measures

Primary Outcomes (1)

  • 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)

    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.

    From Baseline up to Week 78

Secondary Outcomes (6)

  • Time from baseline to clinically meaningful progression on motor signs of the disease (assessed by MDS-UPDRS Part III score)

    From Baseline up to Week 78

  • Time from baseline to any worsening on the Clinical Global Impression - Change (CGI-C) scale

    From Baseline up to Week 78

  • Time from baseline to any worsening on the Patient Global Impression - Change (PGI-C) scale

    From Baseline up to Week 78

  • Change from Baseline to Week 78 in the MDS-UPDRS Total (Part I-IV) score

    From Baseline up to Week 78

  • Change from Baseline to Week 78 in the Modified Hoehn and Yahr score

Eligibility Criteria

Age35 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subjects who satisfy all of the following criteria will be eligible for Part A (Genetic Screening) of the study:
  • The subject is ≥35 and ≤80 years of age at the time of informed consent.
  • The subject has a clinical diagnosis of PD for at least 1 year and for no longer than 7 years before initiation of screening (for Part A), as confirmed by a neurologist using the MDS Criteria for Parkinson's Disease.
  • The subject has a modified Hoehn and Yahr score ≤2.5.
  • The subject is receiving symptomatic treatment for PD.
  • The subject is capable of giving signed informed consent.
  • Subjects who satisfy all the following criteria will be eligible for Part B (Double-Blind Treatment) of the study:
  • Informed Consent - The subject is capable of giving signed informed consent.
  • The subject has a known GBA-PD risk-associated variant (as determined in Part A \[Genetic Screening\] of this study).
  • The subject has a score ≥22 on the Montreal Cognitive Assessment (MoCA) scale.
  • The subject does not have severe motor fluctuations or disabling dyskinesias in the clinical judgment of the investigator.
  • The subject has been on stable doses of PD medications for at least 30 days (at least 60 days for rasagiline) before initiation of screening in Part B (Double-Blind Treatment).
  • The subject is able to comply with the study restrictions.
  • The subject has a body mass index (BMI) of 18 to 40 kg/m2.
  • If a sexually active man or a women of childbearing potential, the subject agrees to use highly effective birth control or to remain abstinent during the trial and for 30 days after the last dose of IMP. Complete abstinence from sexual intercourse if this is the subject's usual and preferred lifestyle; or sexual partner with surgical sterilization (e.g., tubal ligation, hysterectomy and/or bilateral oophorectomy, vasectomy).

You may not qualify if:

  • Subjects who meet any of the following criteria for Part B (Double-Blind Treatment) are not eligible for the study.
  • The subject has Gaucher's disease (GD), as defined by clinical signs and symptoms (i.e., hepatosplenomegaly, cytopenia, skeletal disease), and/or a medical history of marked deficiency of GCase activity compatible with GD.
  • The subject is homozygous for a GBA1 pathogenic variant that is known to be associated with GD or compound heterozygous for 2 alleles that are known to be associated with GD.
  • The subject carries a known PD-associated LRRK2 pathogenic variant.
  • The subject has atypical or secondary parkinsonism by medical history or in the opinion of the investigator. Atypical parkinsonism includes, but is not limited to, diagnoses of progressive supranuclear palsy, cortico-basal syndrome, and multiple system atrophy. Secondary parkinsonism includes drug-induced, toxin-induced, postinfectious, posttraumatic, or vascular parkinsonism.
  • The subject has a history of (within 60 days before initiation of screening) or has planned upcoming major surgery that could interfere with, or for which the treatment might interfere with, the conduct of the study or that would pose an unacceptable risk to the subject in the opinion of the investigator.
  • The subject has any active or chronic disease or condition other than PD that could interfere with, or for which the treatment might interfere with, the conduct of the study or pose an unacceptable risk to the subject in the opinion of the investigator based on medical history, physical examination, vital signs, 12-lead ECG, or clinical laboratory tests. Minor deviations of laboratory values from the normal range may be acceptable if judged by the investigator to have no/minor clinical relevance.
  • The subject has a recent history (last 6 months) of abuse of addictive substances (alcohol, illegal substances), currently uses \>21 units of alcohol per week, or is a regular recreational user of sedatives, hypnotics, tranquillizers, or any other addictive agent in the opinion of the investigator.

  • The subject is using a breast cancer resistance protein (BCRP) substrate (e.g., pravastatin, rosuvastatin, glyburide) at the time of screening for Part B (Double-Blind Treatment).
  • The subject has used any of the following medications within 60 days before Baseline: typical or atypical antipsychotics (including, but not limited to, clozapine, pimavanserin, olanzapine, risperidone, and aripiprazole), metoclopramide, prochlorperazine, methyldopa, tetrabenazine, deutetrabenazine, valbenazine, or reserpine.
  • The subject has received a vaccination within 14 days before administration of the first dose of IMP.
  • The subject has a prior history of or there is a plan to conduct deep brain stimulation (DBS), lesional procedures, (i.e., thalamotomy), or focused ultrasound; to initiate gene therapy treatment for PD; or to initiate use of any formulation of intestinal infusion or continuous subcutaneous infusion of PD medications.
  • The subject is currently participating in or has participated in an investigational drug study within 3 months or 5 half-lives, whichever is longer; in a therapeutic device study within 3 months before the first dose of IMP; or has previously participated in a gene therapy trial. Concurrent participation in an observational study is acceptable.
