The main purpose of this study is to assess the long-term safety and tolerability of paliperidone 6-month PP6M (Dose 1 or Dose 2 [milligram] mg eq.) and to provide access to PP6M in participants with schizophrenia completing the R092670PSY3015 study without relapse.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PP6M injection Dose 1Drug

    Also called R092670

    Participants will receive Dose 1 PP6M intramuscular (IM) injection at Visit 1 (Day) then once every 6 month up to 24 months.

  • PP6M injection Dose 2Drug

    Also called R092670

    Participants will receive Dose 2 PP6M IM injection at Visit 1 (Day) then once every 6 month up to 24 months.

Study groups in NCT04072575
Study groupRoleWhat they receive
Paliperidone Palmitate 6 month(PP6M)ExperimentalParticipants who enter the this open-label extension study immediately after completing Double-blind Phase Study R092670PSY3015 (previous study) will receive Paliperidone Palmitate 6 month (PP6M) intramuscular (IM) injections, dose will be selected based on the unblinded dose level ("moderate" or "higher") that the participant received during previous study. Participants in the "moderate" dose level will receive PP6M Dose 1 and "higher" dose level will receive PP6M Dose 2 during the open-label extension. The PP6M dose level may be adjusted (to Dose 1 or Dose 2) for every 6 month at Visits 3, 5, and 7, based on clinical judgment. Participants who enter this open-label extension study later (up to 3 months after they complete previous study) and were on a moderate or higher dose of PP3M (350 or 525 mg eq.) or PP1M (100 or 150 mg eq.) will receive initial dose of PP6M IM injection (Dose 1 or Dose 2) for every 6 months.
Receives: Drug: PP6M injection Dose 1; Drug: PP6M injection Dose 2

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Relapse

    Number of participants with relapse were reported. Relapse is defined as one or more of the following: a) Psychiatric hospitalization for schizophrenia (involuntary or voluntary admission to a psychiatric hospital for decompensation of the participant's schizophrenic symptoms); b) Emergency Department/Room/Ward visit due to a worsening of the participant's symptoms of schizophrenia, but a psychiatric hospitalization does not occur; c) The participant inflicts deliberate self-injury or exhibits violent behaviour resulting in suicide, clinically significant injury to him/herself or another person, or significant property damage; d) The participant has suicidal or homicidal ideation and aggressive behaviour that is clinically significant (in frequency and severity) in the investigator's judgment.

    Measured: Up to Day 730

  2. Number of Participants With Treatment-emergent Adverse Events (TEAEs)

    An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/ biological agent under study. TEAEs are those events if they started after administration of the first dose and until 183 days after the last dose of study medication.

    Measured: Up to Day 730

Secondary outcomes (3)
  1. Change From Baseline in Clinical Global Impression-Severity (CGI-S) Scale Score

    Change from baseline in CGI-S scale score was reported. CGI-S is defined as clinician-rated scale that assesses the severity of mental illness on a scale of 0 to 7. Considering total clinical experience, a participant was assessed on severity of mental illness at the time of rating according to:1: normal, not at all ill; 2: borderline mentally ill; 3: mildly ill; 4: moderately ill; 5: markedly ill; 6: severely ill; 7: among the most extremely ill participants. A higher score implies a more severe condition.

    Measured: Baseline up to Day 730

  2. Change From Baseline in Personal and Social Performance (PSP) Scale Score

    Change from baseline in PSP scale score was reported. The PSP scale assesses degree of a participant's dysfunction within 4 domains of behavior: 1) socially useful activities, 2) personal and social relationships, 3) self-care, and 4) disturbing and aggressive behavior. Each domain was assessed on a 6-point scale, from 1 (absent) to 6 (very severe) (1 = absent, 2 = mild, 3 = manifest, 4 = marked, 5 = severe, and 6 = very severe). PSP total score was calculated as sum of all the domain scores and ranges from 1 to 100. Participants with score of 71 to 100 had mild degree of difficulty; from 31 to 70, varying degrees of disability; less than or equal to 30, functioning so poorly as to require intensive supervision. Higher score indicates better performance.

    Measured: Baseline up to Day 730

  3. Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score

    Change from baseline in PANSS total score were reported. The neuropsychiatric symptoms of schizophrenia were assessed using the 30-item PANSS scale, which provides a total score (sum of the scores for all 30 items) and scores for 3 subscales: the 7-item positive-symptom (P) subscale, the 7-item negative-symptom (N) subscale, and the 16-item general-psychopathology symptom (G) subscale. Each item is rated on a scale of 1 (absent) to 7 (extreme). The PANSS total score ranges from 30 (absent disease)-210 (more severe neuropsychiatric symptoms of schizophrenia).

    Measured: Baseline up to Day 730

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 5 inclusion and 3 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 29 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 30 sites in Ukraine, Poland, Argentina, Russia, Italy and 1 more country. 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. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 31 May 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Participants With Relapse (time frame: Up to Day 730). The study lists 2 primary outcomes in all. 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 NCT04072575, which also lists 4 linked publications.

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 29 Apr 2025; AzTrials last refreshed its copy on 31 Oct 2026.
