  • Agrees to taper off all prohibited medications prior to baseline
  • On a stable dosage of all permitted medications (with the exception of medication to be used on an as-needed basis) for at least 2 weeks prior to the baseline visit and for the duration of the study

  • A female subject of childbearing potential who is sexually active and using a medically accepted contraceptive method. Acceptable methods include condoms (male or female) with or without spermicidal agent, diaphragm or cervical cap with spermicide, medically prescribed intrauterine device, and hormonal contraceptives. A female subject of childbearing potential who is not currently sexually active must agree that should she be so while participating in the trial, she will use a medically accepted method of contraception for the remainder of the study and for 1 month afterward. Female patients who have had a hysterectomy, bilateral tubal ligation, or bilateral salpingooophorectomy are considered surgically sterile and are thus are exempt from the requirement to use contraception. Female patients who are postmenopausal are considered not of childbearing potential and thus exempt from the contraception requirement; for the purpose of this study, postmenopausal is defined as the permanent cessation of menstruation for at least 12 months prior to screening in women ≥ 45 years of age.
  • Female subjects must have a negative pregnancy test at screening (serum test) and baseline (urine test)
  • Psychotherapy should not be started or changed during a patient's participation in the study. It is acceptable for a patient already receiving psychotherapy to participate in the study
  • Able to speak, read, and understand sufficiently to allow completion of all study assessments
  • Must provide written informed consent prior to the initiation of any protocol-specific procedures

Who cannot join

  • Subjects will not be considered eligible to participate in this study if any one of the following exclusion criteria is satisfied at screening (or at baseline when specified):
  • Presence of an uncontrolled, unstable, clinically significant medical condition (eg, renal, endocrine, hepatic, respiratory, cardiovascular, hematologic, immunologic or cerebrovascular disease, or malignancy) that in the opinion of the investigator could have interfered with the interpretation of safety and PK evaluations
  • Presence of a clinically significant vital sign or physical examination finding that in the opinion of the investigator could potentially interfere with the ability to evaluate safety and tolerability of the trial medication or could impair the subject's ability to complete the trial
  • Presence of a clinically significant abnormality on blood or urine safety tests, which do not improve on retesting. In particular, laboratory and/or clinical evidence of clinically significant hepatic conditions, such as:
  • alanine aminotransferase (ALT) or aspartate aminotransferase (AST) > 3 × upper limit of normal (ULN) and total bilirubin > 2 × ULN; or

About this study

Official title: An Open-Label, One-Sequence Study to Evaluate the Steady- State Comparative Bioavailability of Intramuscular Risperidone ISM® and EU Risperdal® (Sourced From Germany)

This is an Open-Label, One-Sequence Study to Evaluate the Steady- State Comparative Bioavailability of Intramuscular Risperidone ISM® and EU Risperdal® (Sourced From Germany).

Read the detailed description

This was an open-label, 1-sequence study in patients who are were stable oral risperidone treatment. The study consisted of a screening visit, 1 treatment period with inpatient and outpatient visits, and a Follow-up visit.

Patients who were receiving existing oral risperidone treatment (4 mg) continued the oral regimen for 1 week to achieve steady-state concentrations of risperidone (Treatment A). Following the oral risperidone treatment, a single IM dose of 100 mg Risperidone ISM® was administered deeply into the gluteal muscle. A total of 4 IM doses were given, each dose separated by 4 weeks (Treatment B).

Safety assessments and PK sampling were performed once each dosing day and each outpatient visit. A final Follow-up visit was conducted to assess each patient for safety and to obtain PK samples.

Approximately 80 (with no screening failure) patients were planned for enrolment, with the intent to complete 48 patients with the assumption of an approximate drop-out/not valuable PK rate of 40%.

The primary objective of this study was to evaluate the steady-state comparative bioavailability of 100 mg Risperidone ISM® injectable every 4 weeks compared to once-daily 4 mg oral risperidone in patients with schizophrenia stabilized on oral risperidone treatment.

The secondary objective of this study was to evaluate the safety and tolerability of 100 mg Risperidone ISM® injectable every 4 weeks compared to once-daily 4 mg oral risperidone in patients with schizophrenia stabilized on oral risperidone treatment.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Risperidone ISM® 100 mg and Risperdal 4mg Tablet in people with Schizophrenia, run by Rovi Pharmaceuticals Laboratories at 4 sites in United States.

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 14 inclusion and 33 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 5 Jan 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Area under the curve during the dosing interval (AUCtau) (time frame: 28-day period following administration of the fourth dose of risperidone ISM®). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 5 Jan 2022.
