Brief Title  ICMJE Melperone (an Anti-Psychotic) in Patients With Psychosis Associated With Parkinson's Disease
Official Title  ICMJE Safety and Efficacy of Melperone in the Treatment of Patients With Psychosis Associated With Parkinson's Disease
Brief Summary The purpose of this study is to evaluate the safety and efficacy of three target doses of melperone compared to placebo in the treatment of psychosis associated with Parkinson's disease. Subjects will be enrolled at approximately 20 investigational sites in the United States (U.S.) and 15 Ex-US sites. The maximum study duration will be 10 weeks. Subjects will have the option of continuing in an open-label extension study.
Detailed Description Parkinson's Disease is a progressive neurodegenerative disorder characterized by bradykinesia, rigidity, tremor and abnormal posture and gait. Many patients can have mild to moderate symptoms, while others with advanced disease have symptoms which interfere with activities of daily living to a severe degree. Although effective in addressing motor dysfunction, long-term use of anti-Parkinsonian agents has been implicated as a component in the development of psychiatric side effects including psychosis. Treatment of psychosis with typical antipsychotics is not recommended in this patient population, since even low potency typical antipsychotics can cause marked exacerbations of parkinsonism in Parkinson's disease patients. The use of atypical antipsychotics (e.g., clozapine, risperidone and quetiapine) has shown some efficacy in the treatment of psychosis in PD patients. Melperone is classified atypical antipsychotic. European experience with melperone spans more than 30 years, and it encompasses an established antipsychotic efficacy profile in the treatment of confusion, anxiety, unrest (particularly in the elderly) and schizophrenia as well as a favorable safety and tolerability profile. Eligible subjects with Parkinson's disease psychosis will participate in a 1-2 week Screening/Washout Period, a 5 week Titration Phase (one of three doses of melperone or placebo), a 1 week Maintenance Phase and a Taper/Follow-up Period up to 2 weeks. Following the Day 43 assessment, subjects may be given the option of receiving melperone in an open-label extension study.

Eligibility Criteria  ICMJE

Inclusion Criteria:

  • The subject or subject's legally authorized representative (LAR) must sign and date the IRB/IEC approved Informed Consent Form and HIPAA Authorization (applicable to US sites only) prior to study participation.
  • Male or female subjects. If female:

    • Subject is either not of childbearing potential, defined as postmenopausal for at least 1 year or surgically sterile (bilateral tubal ligation, bilateral oophorectomy or hysterectomy), or if of childbearing potential, must comply with a method of birth control acceptable to the investigator during the study, for at least one month prior to randomization and for one month following completion of the study.
    • Subject is not breastfeeding
    • Subjects of childbearing potential must have a negative serum pregnancy test at the screening visit and on Day 1.
  • Subjects with a clinical diagnosis of idiopathic Parkinson's Disease, defined as the presence of at least three of the following cardinal features, in the absence of alternative explanations or atypical features:

    • Rest tremor
    • Rigidity
    • Bradykinesia and/or akinesia
    • Postural and gait abnormalities
  • Subjects with psychosis:

    • Presence of visual and/or auditory hallucinations, with or without delusions, occurring during the four weeks prior to the screening visit.
    • Symptoms severe enough to clinically warrant treatment with an antipsychotic agent.
    • A Hallucinations or Delusions total item score (frequency x severity) of > 4 on the Neuropsychiatric Inventory (NPI).

      • Subjects currently being treated with an antipsychotic agent who have not had visual and/or auditory hallucinations, with or without delusions, during the four weeks prior to screening, and/or have a Hallucinations or Delusions total item score <4 on the NPI at the screening visit may be washed out (for 7 days or 5 half-lives, whichever is longer) and return for a repeat screening visit. The NPI Hallucinations or Delusions total item score must be ≥4 at the repeat visit to be considered for study entry.
  • Subject is on a stable dose of anti-Parkinsonian medication(s) for at least 7 days or 5 half-lives, whichever is longer, prior to the screening visit and is expected to remain on a stable dose for the duration of the study.
  • Subject is willing and able to comply with all study procedures.

Exclusion Criteria:

  • Subject has any systemic factor contributing to the psychosis such as urinary infection, liver disease, renal failure, anemia, infection or cancer.
