POC Study of Pipamperone Added to Stable Treatment With RIS or PAL in Chronic Schizophrenia
November 18, 2014 updated by: PharmaNeuroBoost N.V.
POC Study of Pipamperone 15mg Added to Stable Risperidone or Paliperidone Treatment in Chronic Schizophrenic and Schizoaffective Patients With Residual Symptoms: a Phase I/IIa, Randomized, Double-blind, Placebo-controlled Trial of 7 Weeks
This Phase I/IIa Proof-of-Concept (PoC) trial is designed to assess the effect of adding a single and repeated low dose (15mg/d) of pipamperone (PIP) for 6 weeks to stable treatment with an effective dose of risperidone (RIS) or paliperidone (PAL) on functional MRI tests and clinical outcome of chronic schizophrenic patients with residual, so-called 'positive' symptoms, as well as on cognition, motivation, subjective well-being of patients, negative symptoms, general psychopathological symptoms and safety/tolerability.

Detailed Description
This exploratory study of 7 weeks was intended to be performed in 40 to 60 patients in up to 10 centers in Belgium.
In a subset of patients, the 6-week treatment phase will be preceded by a single-dose cross-over phase with 1 week of wash-out.
While the objective of the study, due to its exploratory design, is to assess any effect of the study medication on MRI or clinical outcome, the study medication is expected to improve the residual (remaining) positive symptom(s) of patients.
In addition, genetic and pharmacokinetic testing may be performed to learn more about the disorder and its treatment.

- Patient has a CGI-S score of 3 (mildly ill) or more at baseline.
- Patient has a score of 4 or more on at least 1 item of the positive PANSS subscale (residual symptoms).
Exclusion Criteria:
