Flexible Dose, Long-term Safety Study of Asenapine for the Treatment of Schizophrenia in Adolescents (P05897)

May 8, 2024 updated by: Organon and Co

A 26-week, Multi-center, Open-label, Flexible Dose, Long-term Safety Trial of Asenapine in Adolescent Subjects With Schizophrenia

This study is designed to evaluate whether asenapine, which is approved by the United States Food and Drug Administration (US FDA) for acute treatment of schizophrenia in adults, is generally safe and well tolerated in adolescents with schizophrenia. This is an extension of base study P05896 (NCT01190254), which means participants must have completed participation in the 8-week base study in order to qualify for this extension study P05897. Participants in this extension study will receive open-label asenapine for 26 weeks. Throughout the study, observations will be made on each participant at various times to assess the long-term safety, tolerability and efficacy of the study treatment.

Study Overview

Status

Status

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

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

8 years to 13 years (Child)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Each participant must be between 12 and 17 years of age at the time of entry on this study, however, participants in the 8-week base study (P05896 [NCT01190254]) who reach 18 years of age while on P05896 may be enrolled in this extension study provided all other inclusion/exclusion criteria are met.
  • Must have completed the 8-week efficacy and safety trial (P05896 [NCT01190254]) and, according to the investigator's judgment, would benefit from long-term treatment.
  • Must have demonstrated an acceptable degree of compliance with trial medication, visits, and other requirements in the 8-week trial (P05896 [NCT01190254]), in the opinion of the investigator.

Exclusion Criteria:

  • A female participant must not be pregnant and must not have the intention to become pregnant during the trial.
  • A participant must not be at imminent risk of self-harm or harm to others.
  • A participant must not currently be under involuntary inpatient commitment.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Asenapine
All enrolled participants receive open-label asenapine 2.5 mg twice daily (BID) on Day 1-3, which is increased to 5.0 mg BID on Day 4 (dose can be increased earlier at the investigator's discretion). Asenapine dosing is flexible for the remainder of the 26-week open-label drug administration period, and can be adjusted to either 2.5 mg or 5.0 mg BID at the investigator's discretion, based on tolerability and/or symptomatology.
Drug: asenapine
asenapine 2.5 mg or 5.0 mg sublingual tablets, administered BID

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
Measure Description
Time Frame
Number of Participants With a Treatment-Emergent Adverse Event (AE) During Extension Study
Time Frame: Up to 30 weeks
An AE was defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. An AE was defined as a "treatment-emergent" AE if it was not present at the extension study baseline, or if it was present at the extension study baseline but worsened in severity compared to baseline during the extension study treatment period.
Up to 30 weeks
Number of Participants Who Discontinued Study Drug During Extension Study Due to an AE
Time Frame: Up to 26 weeks
An AE was defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.
