Conditions

Conditions

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.

Study Type

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.

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 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Diagnosis of schizophrenia or schizoaffective disorder.
  • Inpatients with acute exacerbation of psychotic symptoms.
  • Patients with a minimum score of 40 on the BPRS scale (1-7).

Exclusion Criteria:

  • Concurrent treatment with antipsychotic agents at study drug initiation (within 12 hours prior to study drug initiation); for depot agents a period of two weeks or one cycle, whichever is the longer, must occur between last administration and study drug initiation.
  • Treatment with antidepressants or mood stabilizers within 7 days of start of ziprasidone.
  • Patients currently receiving clozapine.
  • Patients at immediate risk of committing harm to self or others.

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: Arm A
Drug: Ziprasidone
IM ziprasidone at an initial dose of 10 or 20 mg for the first 3 days; additional doses could be administered according to clinical need, with the maximum total daily IM dose of 40 mg. On Day 4, IM treatment was switched to oral (PO) treatment at an initial dose of 40 mg twice daily for the first 2 days; doses could be subsequently adjusted within the range of 40 to 80 mg twice daily. Total treatment duration was 6 weeks.
