Clinical Trial Summary

This is a randomized, double blinded, placebo-controlled Phase II study to investigate the efficacy and safety of ceftriaxone in patients with mild to moderate Parkinson's disease dementia (PDD).This study will enroll approximately 106 patients to have up to 84 evaluable subjects, and conduct in Chung Shan Medical University Hospital, National Taiwan University Hospital, Kaohsiung Chang Gung Memorial Hospital, China Medical University Hospital, Changhua Christian Hospital, and Taipei Veterans General Hospital.


Description:

Parkinson's disease (PD) is a common neurodegenerative disorder that can cause significant disability and decrease quality of life. It is a chronic and progressive disease which means the symptoms become worse over time. Parkinson's disease dementia (PDD) is a decline in thinking and reasoning that develops in many people living with PD at least a year after diagnosis. An estimated 50 to 80 percent of patients with PD eventually experience dementia as the disease progresses. Ceftriaxone is a kind of antibiotics, which has been marketed in many countries. This is the first time for ceftraxone treatment on PDD patient. The primary objective of this Phase II study is to evaluate the improvement of cognitive function in PDD patients with ceftriaxone administration. This study will enroll approximately 106 patients, and conduct in multiple hospitals in Taiwan. Recruitment number of each site will be adjusted according to its enrollment status under the competitive enrollment model. Subjects will receive either ceftriaxone or placebo in a 1:1 ratio. One of the subjects' main caregiver should be involved to get the information of function of daily life and help to complete scale evaluation. The study lasts about 33 weeks, during which eligible patients will be given 1 g/day/dose of ceftriaxone or placebo via injection 3 doses every cycle (2 weekly cycle), for a total of 16 cycles. And the subjects can choose to get injection either in the clinical site or in their house.

Eligibility Inclusion Criteria: 1. Patients are male or female, age 50-85 years, inclusive. 2. Diagnosis of idiopathic Parkinson's disease (PD) based on the UK Parkinson's Disease Society Brain Bank Criteria and with a modified Hoehn and Yahr Stage of I to IV. 3. Patients have been receiving stable dose of medications equivalent up to 1800 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. 4. Diagnosis of PDD based on Movement Disorder Society (MDS) Task Force criteria as the following items: 1. A diagnosis of PD based on UK Parkinson's Disease Society Brain Bank Criteria 2. PD development prior to the onset of dementia based on patient/caregiver history or records 3. Cognitive deficiency severe enough to impair daily life based on patient/caregiver interview or questionnaire 4. 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. Note that MMSE range 16-25 for illiterate. Illiterate is defined as no education history. 5. 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. 6. 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. 1. 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). 2. 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. 3. Male sterilization (at least 6 months prior to screening).

Patients with the following medications that could put patients at risk, interfere with study evaluations, or prevent meeting the requirements of the study at the judgement of PI should be excluded : 1. Centrally acting anticholinergic medication currently or within 4 weeks prior to the screening visit. 2. Cocaine, opioids, ethanol (binge drinking or heavy alcohol defined by SAMHSA and NIAAA) currently or within 4 weeks prior to the screening visit; amphetamines, cannabinoids abuse history or taking currently or within 3 months prior to the screening visit. 3. Acetylcholinesterase inhibitors or memantine currently or within 4 weeks prior to the screening visit, except that patients have been stable controlled and have been receiving stable dose of the acetylcholinesterase inhibitors or memantine for at least 4 weeks prior to screening or are considered being optimally treated at screening without further dose adjustments needed as judged by the Investigator. 4. Ceftriaxone or cephalosporin or penicillin or ß-lactam currently or within 4 weeks prior to the screening visit. 5. Neuroleptics or antipsychotics for treatment of psychotic symptoms (e.g., hallucinations) within 4 weeks prior to the screening visit, except that patients have been stable controlled and have been receiving stable dose of the neuroleptics or antipsychotics for at least 4 weeks prior to screening or are considered being optimally treated at screening without further dose adjustments needed as judged by the Investigator. 6.

Other Net change of biomarker Aß42 data Patients' plasma samples will be collected to analyze a-synuclen by immunomagnetic reduction (IMR) assay kit developed by Magqu Company. from baseline to week 17 and 33 visits
Primary Compare the treatment difference in mean net change in ADAS-Cog score with time course ADAS-Cog is a validated instrument to assess dementia covering memory, orientation, language, praxis and consisting of 11 items. The total possible scores range from 70 (severe impairment) to 0 (no impairment). from baseline to week 17 and 33 visits
Secondary Changes in Unified Parkinson's Disease Rating Scale (UPDRS) score The UPDRS system is a composite scale intended for rating patients with PD. Scores are rated as 0-4 (0-1 for some Part IV), representing 0=normal and 1 or 4=maximal deficit, symptoms, or impairment. from baseline to week 17 and 33 visits
Secondary Changes in Judgment of Line Orientation score The Judgment of Line Orientation (JLO) test is a widely used measure of visuospatial judgment. A score of 17 or less is considered a sign of severe deficit. from baseline to week 17 and 33 visits
Secondary Changes in Mini-Mental State Examination (MMSE) score The MMSE is a brief, quantitative measure of cognitive status in adults. The instrument examines orientation, registration, attention, calculation, recall, visuo-spatial abilities and language. The maximum score is 30, with higher scores indicating better cognitive function. from baseline at week 17 and 33 visits
Secondary Changes in Clinical Dementia Rating (CDR) Scale score The CDR Scale is a 5-point scale used to characterize 6 domains of cognitive and functional performance applicable to related dementias: memory, orientation, judgment & problem solving, community affairs, home & hobbies, and personal care. This score is useful for characterizing and tracking a patient's level of impairment/dementia with 0=normal, 0.5 =very mild dementia, 1=mild dementia, 2=moderate dementia, 3=severe dementia. from baseline to week 17 and 33 visits
Secondary Changes in Color Trail Test score Color Trail Test provides quantitative and qualitative information by two trials. The length of time to complete each trial is recorded, along with qualitative features of performance indicative of brain dysfunction, such as near-misses, prompts, number sequence errors, and color sequence errors. from baseline to week 17 and 33 visits
Secondary Changes in MRI image for atrophy rate of brain Multimodal MRI examinations will be performed on a 3T MRI scanner with a standard 8-channel head coil. Region of interest in the brain will be evaluated for functional changes including atrophy rate from baseline data. from baseline to week 17 and 33 visits
Secondary Changes in MRI image for dopaminergic projection from substantia nigra to striatum Multimodal MRI examinations will be performed on a 3T MRI scanner with a standard 8-channel head coil. Region of interest in the brain will be evaluated for functional changes including dopaminergic projection from baseline data. from baseline to week 17 and 33 visits
Secondary Changes in Tc-99m TRODAT SPECT image SPECT assessment will use Tc-99m, a radio tracer with high selectivity and specificity for the striatum dopamine transporter (DAT) density evaluation. DAT density change from baseline will be calculated from region of interest drawn in the striatum by independent readers. from baseline to week 17 and 33 visits
