NCT ID: NCT01933919

Last Updated: 2017-12-04

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE3
• Total Enrollment: 38 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2013-08-14
• Study Completion Date: 2016-07-01

Brief Summary

The objective of the first phase of this study is to evaluate the efficacy of fluvoxamine compared to placebo on change in total score of Japanese version of the Children's Yale-Brown Obsessive Compulsive Scale (JCY-BOCS) 10-item from baseline to the last observation visit (10 weeks) in pediatric/adolescent participants with obsessive compulsive disorder (OCD).

The objective of the second phase of the study is to evaluate the long-term safety and efficacy of fluvoxamine in pediatric/adolescent patients with OCD.

Detailed Description

The first phase will be conducted in a randomized, placebo-controlled, double-blind manner to evaluate the efficacy of fluvoxamine on change from baseline to the last observation visit in the JCY-BOCS 10-item total score. Eligible patients will be allocated to the fluvoxamine group or placebo group in a 1:1 ratio using the experience of fluvoxamine treatment and age as stratification factors (dynamic allocation). The first phase consists of a screening period of 1-2 weeks, a forced titration dose period of 2 weeks, a dose adjustment period of 4 weeks, a maintained dose period of 4 weeks, and a tapering dose period of 0-4 weeks.

The 2nd phase will be conducted in an open-label manner in participants who completed the first phase to evaluate the long-term safety of fluvoxamine. The 2nd phase consists of 3 periods; a forced titration dose period of 2 weeks, a flexible dose period of 50 weeks, and a tapering dose period of 0-4 weeks. After the last dose of study drug (including tapering dose period) or the early termination visit, participants will be followed for up to 30 days.

Study Groups

placebo

In the double-blind placebo-controlled phase participants received one placebo tablet a day in week 1, then one placebo tablet twice a day (BID) in week 2 followed by a dose adjustment period from weeks 3 to 6 where the dose could be escalated by one tablet/day/week up to a maximum of three tablets twice a day. From weeks 7 to 10 participants received the same dose that was given during week 6. At the end of the 10-week treatment period there was a dose-tapering period of up to 4 weeks where the dose was decreased by up to two tablets/day each week.

In the open-label long-term phase participants received 25 mg fluvoxamine once a day for the first week, 25 mg BID in week 2 followed by a flexible dose period from weeks 3 to 52 where the dose could be escalated by one tablet/day/week up to a maximum of 150 mg/day (three tablets BID). At the end of the 52-week treatment period there was a dose-tapering period of up to 4 weeks where the dose was decreased by up to 50 mg/day each week.

Fluvoxamine

In the double-blind placebo-controlled phase participants received 25 mg fluvoxamine once a day in week 1, 25 mg twice a day (BID) in week 2 followed by a dose adjustment period from weeks 3 to 6 where the dose could be escalated by 25 mg/day/week up to a maximum of 150 mg (three tablets BID). From weeks 7 to 10 participants received the same dose that was given during week 6. At the end of the 10-week treatment period there was a dose-tapering period of up to 4 weeks where the dose of decreased by up to 50 mg/day each week.

In the open-label long-term phase participants received 25 mg fluvoxamine once a day for the first week, 25 mg BID in week 2 followed by a flexible dose period from weeks 3 to 52 where the dose could be escalated by 25 mg/day/week up to a maximum of 150 mg/day (three tablets BID). At the end of the 52-week treatment period there was a dose-tapering period of up to 4 weeks where the dose was decreased by up to 50 mg/day each week.
