Parkinson's Disease Dementia
About this trial
This is an interventional treatment trial for Parkinson's Disease Dementia focused on measuring Parkinson's Disease, Parkinson's Disease Dementia
Eligibility Criteria
Inclusion Criteria:
- Patients are male or female, age 50-80 years, inclusive.
- Diagnosis of idiopathic Parkinson's disease (PD) within less than 10 years duration based on the UK Parkinson's Disease Society Brain Bank Criteria and with a modified Hoehn and Yahr Stage of I to III.
- Patients have been receiving stable dose of medications equivalent up to 800 mg/day of levodopa for Parkinson's disease at least 2 weeks prior to screening and patients are considered as being optimally treated at screening and no known further adjustments of current medication needed to improve the subject's status of PD during the study period by the judgment of the Investigator based on the subject's history, previous treatments, and the clinical presentation.
Diagnosis of PDD based on Movement Disorder Society (MDS) Task Force criteria as the following items:
- A diagnosis of PD based on UK Parkinson's Disease Society Brain Bank Criteria
- PD development prior to the onset of dementia based on patient/caregiver history or records
- Cognitive deficiency severe enough to impair daily life based on patient/caregiver interview or pill questionnaire
- Impairment of at least 2 of the following domains: attention, executive function, visuo-constructive ability, memory Besides, patients' Mini-Mental State Examination (MMSE) should be in the range of 18-25 (inclusive) or CDR scale in the range of 0.5-2 and are currently not taking any treatment for dementia.
- Patients who are eligible and able to participate in the study must be judged by the investigator to evaluate the competency of providing informed consent for this dementia related study (the decision making is based on MacArthur Competence Assessment concept) and should be able to understand the language in which the tests require so and must be able to perform all the assessments.
All male and female patients with child-bearing potential (between puberty and 2 years after menopause) should use at least any one of the appropriate contraception methods shown below, for during and at least 4 weeks after ceftriaxone treatment.
- Total abstinence (when this is in line with the preferred and usual lifestyle of the subject. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception).
- Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy) or tubal ligation at least six weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment.
- Male sterilization (at least 6 months prior to screening). For female subjects on the study, the vasectomized male partner should be the sole partner for that subject
- Combination of any two of the following listed methods: (d.1+d.2 or d.1+d.3, or d.2+d.3):
d.1 Use of oral, injected or implanted hormonal methods of contraception or other forms of hormonal contraception that have comparable efficacy (failure rate <1%), for example hormone vaginal ring or transdermal hormone contraception.
d.2 Placement of an intrauterine device (IUD) or intrauterine system (IUS). d.3 Barrier methods of contraception: Condom or Occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/vaginal suppository.
Exclusion Criteria:
- Any indication of forms of Parkinsonism other than idiopathic PD.
- Diagnosis of possible PDD.
- Diagnosis of dementia with Lewy Bodies.
- Mental/physical/social condition which could preclude performing efficacy or safety assessments.
- Medical history of brain or other clinically significant neurological/psychiatric disorders or injuries other than PD or PDD.
- The patients have received neurosurgical intervention related to PD (e.g. deep brain stimulation (DBS), thalamotomy etc.) or are scheduled to do so during the trial period.
- The patients have history of allergic response to levodopa, ceftriaxone, cephalosporin class of drugs or ursodiol or lidocaine.
- Malignant neoplastic disease, either currently active or in remission for less than 1 year.
- Clinically significant and unstable gastrointestinal, renal, endocrine, pulmonary, or cardiovascular disease, including not well controlled hypertension, asthma, chronic obstructive pulmonary disease, and diabetes, hyperbilirubinemia, impaired vitamin K synthesis or low vitamin K stores that would hinder or interfere participation to the study in the opinion of the Investigator.
- Patients with a history of hepatobiliary and /or pancreatic disease or abdominal ultrasound examination imaging shows biliary system disease during screening.
- The patients are currently experiencing unpredictable or intractable or troublesome dyskinesia or fluctuations in their symptoms.
Patients with the following medications that could put patients at risk, interfere with study evaluations, or prevent meeting the requirements of the study should be excluded :
- Anticholinergic medication or amantadine currently or within 4 weeks prior to the screening visit.
- Cocaine, opioids, ethanol (binge drinking or heavy alcohol defined by SAMHSA and NIAAA) currently or within 4 weeks prior to the screening visit; nicotine dependence, amphetamines, cannabinoids abuse history or taking currently or within 3 months prior to the screening visit.
- Acetylcholinesterase inhibitors or memantine currently or within 4 weeks prior to the screening visit.
- Ceftriaxone or cephalosporin or penicillin or β-lactam currently or within 4 weeks prior to the screening visit.
- Neuroleptic for treatment of psychotic symptoms (e.g., hallucinations) related to their anti-Parkinson medication within 4 weeks prior to the screening visit.
- Antipsychotics currently or within 4 weeks prior to the screening visit.
- A drug that has severe hepatotoxic or renal toxic within 4 weeks prior to the screening visit.
- Warfarin, cyclosporin, vancomycin, amsacrine, aminoglycosides, fluconazole, chloramphenicol currently or within 4 weeks prior to the screening visit.
- Currently participating in another clinical trial or who participated in a previous clinical trial and received any investigational product treatment within 4 weeks prior to the screening visit.
- Signs and symptoms suggestive of transmissible spongiform encephalopathy, or family members who suffer from such.
- Patients who are not able to take MRI and TRODAT SPECT examination.
- Patients who are pregnant or breast feeding.
