A Comparison of the Pharmacokinetics and Safety of Long-acting Injectable Risperidone When Administered to Gluteal or Deltoid Intramuscular Injection Sites in Stable Schizophrenia Patients.

June 2, 2011 updated by: Johnson & Johnson Pharmaceutical Research & Development, L.L.C.

Comparative Single-Dose Pharmacokinetics and Safety of Gluteal and Deltoid Intramuscular Injection of Long-Acting Injectable Risperidone in Subjects With Chronic Stable Schizophrenia

The purpose of this study is to compare the pharmacokinetics and safety of long-acting injectable risperidone, an atypical antipsychotic medication used for the treatment of patients with schizophrenia, when it is administered as an intramuscular injection via the deltoid muscle, compared with intramuscular injection via the gluteal muscle.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a randomized, open label, single dose, multicenter, 2-way crossover study comprising a screening phase, 2 open-label treatment periods, and end-of-study evaluations. The study population will comprise patients with chronic stable schizophrenia. Patients will be allowed to continue on their existing oral antipsychotic treatment throughout the study, if not receiving disallowed mediations, per protocol. Patients will be randomly allocated to receive treatment in 1 of 2 panels. In each panel, patients will receive a single intramuscular injection of long-acting injectable risperidone in each treatment period, in a 2-way crossover design. In Panel I, patients will receive 25 mg long-acting injectable risperidone via the gluteal muscle and 37.5 mg long-acting injectable risperidone via the deltoid muscle during the study period. In Panel II, patients will receive 50 mg long-acting injectable risperidone via the gluteal muscle and 50 mg long-acting injectable risperidone via the deltoid muscle. There will be a washout period of 85 days between each administration of study drug. The primary outcome will be comparison of the pharmacokinetic parameters area under the curve (AUC) and peak plasma concentration (Cmax) for 37.5 mg deltoid versus 25 mg gluteal, and for 50 mg deltoid versus 50 mg gluteal. Safety will be assessed at screening, throughout the open-label treatment phase, and at the end of study or early withdrawal using a combination of adverse events (including occurrence of extrapyramidal symptoms as assessed by the Extrapyramidal Symptoms Rating Scale), clinical laboratory tests (hematology, serum chemistry, urinalysis, and pregnancy testing), vital signs, physical examinations, electrocardiograms, and injection site evaluation. The study hypothesis is that intramuscular injections of long-acting injectable risperidone via the gluteal and deltoid sites will be bioequivalent routes of administration, as measured by peak and total drug concentrations in the plasma, and that the safety and tolerability profiles of the 2 injection sites will be comparable. The patients will receive a single injection of long--acting injectable risperidone (25 mg, 37.5 mg or 50 mg) in their gluteal or deltoid muscle in 2 treatment periods.

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 55 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

  • Chronic schizophrenia of any subtype, according to Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) criteria
  • stable schizophrenia without any changes in medications or dosage during the 4 weeks before the screening visit
  • Clinical Global Impression scale score of <=3 (mild)
  • informed consent signed by the patient
  • patient is otherwise healthy on the basis of a prestudy physical examination and medical history.

Exclusion Criteria:

  • No DSM-IV Axis I diagnosis other than schizophrenia

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Comparison of the pharmacokinetic parameters AUC and Cmax for 37.5 mg deltoid versus 25 mg gluteal, and for 50 mg deltoid versus 50 mg gluteal based on blood sampling at predefined intervals up to 85 days.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Patient-rated local site injection pain (measured on a visual analogue scale) & investigator-rated local site injection reaction (measured by injection site evaluation scale) measured 30 min. before injection & at regular intervals up to Day 15

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
