Trial summary

Negative symptoms and cognitive deficits are two partially-related features of schizophrenia which have a major negative impact on social function and objective quality of life. Standard drug treatments have little impact on either and arguably no effect on primary negative symptoms. Read more about this study

About this study

Official title: Randomized Double Blind Placebo Controlled Study of Ondansetron and Simvastatis Added to Treatment As Usual in Patients with Schizophrenia

Negative symptoms and cognitive deficits are two partially-related features of schizophrenia which have a major negative impact on social function and objective quality of life. Standard drug treatments have little impact on either and arguably no effect on primary negative symptoms. Social dysfunction has major economic consequences in both the developed and developing world. There is evidence that anti-inflammatory treatment may have beneficial effects in patients with schizophrenia.

Read the detailed description

Negative symptoms and cognitive deficits are two partially-related features of schizophrenia which have a major negative impact on social function and objective quality of life. Evidence indicates that anti-inflammatory treatment may have beneficial effects in schizophrenia. From our preliminary randomised double-blind placebo-controlled clinical trial in Pakistan and Brazil, it is indicated that addition of minocycline (an antibiotic and anti-inflammatory drug) for one year to treatment as usual (TAU) reduced negative symptoms and improved some cognitive measures (Chaudhry et al 2009).

Statins are primarily HMG-CoA reductase inhibitors also anti-inflammatory agents and known to decrease C-reactive protein (CRP). Higher levels of CRP (>0.50 mg/dl) are associated with marked negative symptoms and higher total PANSS scores in patients with schizophrenia. (Fan et al 2007)

Ondansetron, a selective 5-hydroxytryptamine-3 antagonist, is quite commonly used as an antiemetic in cancer patients (Marty et al 1990). There are several small trials suggesting that ondansetron as an adjunct to antipsychotics is effective in improving negative symptoms and memory in patients suffering from schizophrenia (Ahkonzadeh et al 2009, Levkovitz et al 2005 and Zhang et al 2006).

The Primary objective of this study is addition of ondansetron and /or simvastatin to TAU for patients with schizophrenia will result in improvement in negative symptoms

The Secondary objectives include:

  • improvement in positive or other symptoms
  • social functioning
  • cognitive functions
  • additive effects of ondansetron and simvastatin

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Ondansetron, Simvastatin and Odansetron plus simvastatin in people with Schizophrenia and Schizoaffective Disorder, run by Pakistan Institute of Living and Learning at 3 sites in Pakistan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Pakistan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Negative symptom severity (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01602029, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Dec 2024.
