Outcome Measures

Primary Outcomes (1)

  • Change in Attentional Intensity Index composite factor score from baseline to week 12

    The Attentional Intensity Index composite factor score combines the speed scores from the three attention tasks (simple reaction time, choice reaction time and digit vigilance), and has been validated using factor analysis. The measure reflects the ability to focus attention and process information.

    From baseline to week 12 (end of treatment period).

Secondary Outcomes (21)

  • Change in Attentional Intensity Index composite factor score from baseline to week 6

    From baseline to week 6 (mid-point of treatment period)

  • Change in Sustained Attention Index composite factor score from baseline to week 6 and week 12

    From baseline to week 6 (mid-point of treatment period) and week 12 (end of treatment period)

  • Change in Working Memory Index composite factor score from baseline to week 6 and week 12

    From baseline to week 6 (mid-point of treatment period) and week 12 (end of treatment period)

  • Change in Episodic Memory Index composite factor score from baseline to week 6 and week 12

    From baseline to week 6 (mid-point of treatment period) and week 12 (end of treatment period)

  • Change in Memory Speed Retrieval Index composite factor score from baseline to week 6 and week 12

    Fom baseline to week 6 (mid-point of treatment period) and week 12 (end of treatment period)

  • +16 more secondary outcomes

Other Outcomes (5)

  • Screening/Baseline whole-brain and regionally specific brain volumes as predictors of treatment response

    At screening/baseline (pre-medication dosing)

  • Screening/Baseline whole-brain perfusion as well as perfusion in ROIs as predictors of treatment response

    At screening/baseline (pre-medication dosing)

  • Screening/Baseline functional resting-state connectivity of the large-scale cognitive brain networks as predictors of treatment response

    At screening/baseline (pre-medication dosing)

  • +2 more other outcomes

Study Arms (2)

Active drug: AZD0328

EXPERIMENTAL

Participants will receive AZD0328 capsules for oral administration.AZD0328 is a selective α7 nicotinic receptor agonist, The total daily dosage of AZD0328 is 1mg per day; administered as 0.5mg twice daily / BID. The study treatment period is 12-weeks.

Drug: AZD0328

Placebo

PLACEBO COMPARATOR

Participants will receive identical-appearing placebo capsules for oral administration.Participants will be instructed to take 2 capsules in the morning and 2 capsules in the evening for a 12-week period.

Drug: Placebo

Eligibility Criteria

Age50 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Aged between 50 to 80 years (inclusive) at time of consent
  • Duration of motor symptoms of at least 1 year
  • Hoehn and Yahr stage between 1 and 3 (inclusive) in ON state
  • Diagnosis of PD according to United Kingdom (UK) Brain Bank criteria
  • Score on Clinical Dementia Rating (CDR) scale = 0.5
  • Diagnosis of PD-MCI according to MDS PD-MCI, Level I criteria
  • Duration of cognitive impairment of at least 3 months (to distinguish from mild delirium)

You may not qualify if:

  • Insufficient fluency in English or local language to complete assessments
  • Severe visual or auditory impairment that may interfere with participant's ability to complete assessments
  • Unable to provide informed consent at screening visit
  • Participation in a clinical study involving an investigational drug within 4 months prior to screening
  • Smoking (cigarettes, pipes, cigars, e-cigarettes etc.) or use of smokeless tobacco products (chewing / dipping tobacco, snuff etc.) or anti-smoking nicotine containing products (patches/gum/sprays etc.), within the last 12 weeks
  • HADS depression subscale score ≥ 11
  • History of deep brain stimulation or other neurosurgical procedure
  • Diagnosis of dementia, including Parkinson's disease dementia (PDD) or Dementia with Lewy Bodies (DLB).
  • Diagnosis of schizophrenia, bipolar disorder or other psychotic disorder
  • Malignant neoplasms within 3 years of screening (except for basal or squamous cell carcinoma of the skin); or had curative surgery/treatment and has been free of malignancy for at least 12 months)
  • Any medical condition that in the opinion of the investigator may be contributing to cognitive impairment, above and beyond that caused by the participant's PD,
  • Current evidence of any other medical condition not stably or adequately controlled, and which in the opinion of the investigator may affect participant safety or study participation
  • Using any prohibited medications or permitted medications that do not meet stable dosing regimen requirements, as specified in section 5.7
  • Clinically significant vital sign or ECG measure at screening or baseline visit, that in the opinion of the investigator would prevent participant from safely participating in this study
  • Clinically significant clinical laboratory result from screening visit, that in the opinion of the investigator would prevent participant from safely participating in this study
  • +6 more criteria
