Brief Summary:
To establish the safety and efficacy of HTL0018318 compared with placebo when administered once daily for 12 weeks to patients with dementia with Lewy bodies.

Condition or disease Intervention/treatment Phase
Dementia With Lewy Bodies Drug: HTL0018318 Drug: Placebo Phase 2

Detailed Description:
To assess the safety, tolerability and efficacy of HTL0018318 at 3 dose levels (once daily) compared with placebo over a 12-week treatment period in patients with dementia with Lewy bodies (DLB). Approximately 140 DLB patients who have not received donepezil (Aricept®) and/or other acetyl cholinesterase inhibitors (AchEi) and approximately 32 DLB patients who have had prior treatment experience with donepezil but have stopped usage will be enrolled.

    Comparison of HTL0018318 treatment with placebo


Secondary Outcome Measures :
  1. Change from baseline in measures of cognitive impairment [ Time Frame: Baseline to 12 weeks ]
    Comparison of HTL0018318 treatment with placebo

  2. Change from baseline in measures of psychosis (i.e. hallucinations and delusions) [ Time Frame: Baseline to 12 weeks ]
    Comparison of HTL0018318 treatment with placebo

Criteria

Inclusion Criteria:

  • Diagnosed with probable DLB according to the fourth revision of consensus diagnostic criteria for DLB.
  • Clinical imaging evidence from either SPECT or MIBG cardiac scintigraphy that is consistent with a clinical diagnosis of DLB.
  • Partner or caregiver able to support the patient for the duration of the clinical trial.

Exclusion Criteria:

  • Patients with poorly controlled hypertension despite lifestyle modifications and/or pharmacotherapy, who are currently on more than 2 different antihypertensive treatments
  • Patients with prominent, recurrent episodes of syncope are related to orthostatic hypotension
  • Patients with pulmonary disease or evidence of clinically significant moderate or severe pulmonary symptoms
  • Patients who are taking a range of prohibited and restricted medication
  • Patients who have been prescribed individualised cognitive rehabilitation, stimulation or training that was performed under medical supervision in the 6 months prior to the screening visit
