Ziprasidone in Pediatric Bipolar Disorder

Ziprasidone in Pediatric Bipolar Disorder: a 6-week, Open-label Comparison of Rapid vs. Slow Dose Titration

This is a 6 week, open-label, blinded-rater, randomized, controlled, pilot study designed to determine the dosing, safety and efficacy of ziprasidone in the treatment of pediatric bipolar disorder (PBD). In this pilot study we are comparing the efficacy of rapid versus slow dose titration of ziprasidone in PBD. The investigators hypothesize that subjects on ziprasidone monotherapy will have a reduction in manic symptoms. Also, the investigators hypothesize that slower titration of ziprasidone will result in lesser side effects which will assist in medication compliance as measured by patient report and pill count.

Study Overview

• Status: Completed
• Conditions: Bipolar Disorder
• Intervention / Treatment: Drug: Ziprasidone; Drug: Ziprasidone

Detailed Description

This study will enroll approximately 60 children and adolescents aged 10-17 years who have been diagnosed with bipolar disorder. Their participation will last about 8 weeks (2 weeks of screening and 6 weeks of medication management) and enrollment will last for two years. After the screening period, all subjects who meet inclusion/exclusion criteria will be randomized to either rapid or slow dose titration of ziprasidone. Subjects in the rapid titration group will reach their maximum dose of study drug over 2 weeks, subjects in the slow titration group over 4 weeks. The study doctor may deviate from the dosing schedule if clinically indicated. The primary data analysis of this pilot study will examine the effect of rapid- versus slow-dose titration of ziprasidone on manic symptoms.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: ziprasidone rapid dose; Rapid Dose Titration Group	Drug: Ziprasidone; Subjects will be treated openly with Ziprasidone for 6 weeks. Dose will be titrated from 20 mg to a maximum of 160 mg. Arm 1 will have the dose of Ziprasidone titrated at a rate of 20 mg every 2 days, reaching the maximum dose in 14 days. Final dose of Ziprasidone will be determined by symptoms reduction and the presence or absence of side effects.; Other Names: Geodon; Drug: Ziprasidone; Subjects will be treated openly with Ziprasidone for 6 weeks. Dose will be titrated from 20mg to a maximum of 160mg. Arm 2 will have the dose of Ziprasidone titrated at a rate of 20mg every 3-4 days, reaching the maximum dose in 25 days. Final dose of Ziprasidone will be determined by symptoms reduction and the presence or absence of side effects.; Other Names: Geodon
Active Comparator: ziprasidone slow dose; Slow Dose Titration Group	Drug: Ziprasidone; Subjects will be treated openly with Ziprasidone for 6 weeks. Dose will be titrated from 20 mg to a maximum of 160 mg. Arm 1 will have the dose of Ziprasidone titrated at a rate of 20 mg every 2 days, reaching the maximum dose in 14 days.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Young Mania Rating Scale (YMRS)	The Young Mania Rating Scale (YMRS) is a measure of the severity of manic symptoms. The scores on the scale range from 0-56. A score of more than or equal to 14 was the cut off for inclusion into this study. A higher score denotes increased severity of manic symptoms.	6 weeks of treatment

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Children's Depression Rating Scale	The CDRS-R is a 17 item clinician-rated instrument used to measure severity of depressive symptoms in youth (ages 6-18). Each item is rated on a 1 to 5 or 1 to 7 point scale, with a 1 describing absence of the given symptom. The CDRS-R yields a total score from 17 to 113 with a score of 40 or greater considered to symptomatic of depression. Scores of 35-40 indicate mild depression, 29-34 is borderline and <28 is no depression.	6 weeks of treatment
Clinical Global Impressions-Severity (CGI-S) Scale	The CGI-S assesses clinical severity. The CGI-S is a seven point scale where 1 is the minimum value and 7 is the maximum value. Lower scores mean a better outcome. The CGI-Severity scale scores are: 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 patients.	6 weeks of treatment
SAFTEE (Side Effects Rating Scale)	The Systematic Assessment for Treatment of Emergent Events (SAFTEE) is one of the first comprehensive Adverse effects-elicitation instruments developed specifically for use in psychiatric clinical trials. The SAFTEE is a standardized method, which increases consistency of Adverse Effects data, both within and across clinical trials.It allows ratings of five levels of severity and collects information about the onset, duration, pattern, judgement of attribution of cause, and action taken by the clinician. Suggested probe questions are also provided, which the clinician can use to elicit detailed information about the AE. Furthermore, the SAFTEE requires the clinician to determine a time interval of inquiry to be used in the trial. Adverse Effects are graded as None=0, Mild=1, Moderate=2, Severe=3.	6 weeks of treatment
AIMS (Abnormal Involuntary Movement Scale)	AIMS is a 12-item instrument assessing abnormal involuntary movements associated with antipsychotic drugs, such as tardive dystonia and chronic akathisia, as well as 'spontaneous' motor disturbance related to the illness itself. Scoring the AIMS consists of rating the severity of movement in three main anatomic areas (facial/oral, extremities, and trunk), based on a five-point scale (0=none, 4=severe).	6 weeks of treatment
Barnes Akathisia Rating Scale (BARS)	The BARS measures drug-induced akathisia occurring specifically with use of neuroleptic agents. It is a four-item fully anchored scale. Three items (objective akathisia, subjective awareness of restlessness, and subjective distress related to restlessness) are rated on a 4-point scale (0= normal and 9= most severe) and, the global clinical assessment of akathisia uses a 5-point scale (0= normal and 4= most severe). Total scores ranged from 0-13 with higher scores reflecting more akathisia.	6 weeks of treatment
