Adults with OCD

The effectiveness of sertraline hydrochloride in the treatment of OCD was demonstrated in three multicenter placebo-controlled studies of adult (age 18 to 65) non-depressed outpatients (Studies OCD-1, OCD-2, and OCD-3). Patients in all three studies had moderate to severe OCD (DSM-III or DSM-III-R) with mean baseline ratings on the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) total score ranging from 23 to 25.

  * Study OCD-1 was an 8-week randomized, placebo-controlled study with flexible dosing of sertraline hydrochloride in a range of 50 to 200 mg/day, titrated in 50 mg increments every 4 days to a maximally tolerated dose; the mean dose for completers was 186 mg/day. Patients receiving sertraline hydrochloride (N=43) experienced a mean reduction of approximately 4 points on the Y-BOCS total score which was statistically significantly greater than the mean reduction of 2 points in placebo-treated patients (N=44). The mean change in Y-BOCS from baseline to last visit (the primary efficacy endpoint) was -3.79 (sertraline hydrochloride) and -1.48 (placebo).
  * Study OCD-2 was a 12-week randomized, placebo-controlled fixed-dose study, including sertraline hydrochloride doses of 50, 100, and 200 mg/day. Sertraline hydrochloride (N=240) was titrated to the assigned dose over two weeks in 50 mg increments every 4 days. Patients receiving sertraline hydrochloride doses of 50 and 200 mg/day experienced mean reductions of approximately 6 points on the Y-BOCS total score, which were statistically significantly greater than the approximately 3 point reduction in placebo-treated patients (N=84). The mean change in Y-BOCS from baseline to last visit (the primary efficacy endpoint) was -5.7 (pooled results from sertraline hydrochloride 50 mg, 100 mg, and 150 mg) and -2.85 (placebo).
  * Study OCD-3 was a 12-week randomized, placebo controlled study with flexible dosing of sertraline hydrochloride tablets in a range of 50 to 200 mg/day; the mean dose for completers was 185 mg/day. Sertraline hydrochloride (N=241) was titrated to the assigned dose over two weeks in 50 mg increments every 4 days. Patients receiving sertraline hydrochloride experienced a mean reduction of approximately 7 points on the Y-BOCS total score which was statistically significantly greater than the mean reduction of approximately 4 points in placebo-treated patients (N=84). The mean change in Y-BOCS from baseline to last visit (the primary efficacy endpoint) was - 6.5 (sertraline hydrochloride) and -3.6 (placebo).



Analyses for age and gender effects on outcome did not suggest any differential responsiveness on the basis of age or sex.

The effectiveness of sertraline hydrochloride was studied in the risk reduction of OCD relapse. In Study OCD-4, patients ranging in age from 18 to 79 meeting DSM-III-R criteria for OCD who had responded during a 52-week single-blind trial on sertraline hydrochloride 50 to 200 mg/day (n=224) were randomized to continuation of sertraline hydrochloride or to substitution of placebo for up to 28 weeks of observation for analysis of discontinuation due to relapse or insufficient clinical response. Response during the single-blind phase was defined as a decrease in the Y-BOCS score of ≥ 25% compared to baseline and a CGI-I of 1 (very much improved), 2 (much improved) or 3 (minimally improved). Insufficient clinical response during the double-blind phase indicated a worsening of the patient's condition that resulted in study discontinuation, as assessed by the investigator. Relapse during the double-blind phase was defined as the following conditions being met (on three consecutive visits for 1 and 2, and condition 3 being met at visit 3):

  * Condition 1: Y-BOCS score increased by ≥ 5 points, to a minimum of 20, relative to baseline;
  * Condition 2: CGI-I increased by ≥ one point; and
  * Condition 3: Worsening of the patient's condition in the investigator's judgment, to justify alternative treatment.



Patients receiving continued sertraline hydrochloride treatment experienced a statistically significantly lower rate of discontinuation due to relapse or insufficient clinical response over the subsequent 28 weeks compared to those receiving placebo. This pattern was demonstrated in male and female subjects.

Pediatric Patients with OCD

The effectiveness of sertraline hydrochloride for the treatment of OCD was demonstrated in a 12-week, multicenter, placebo-controlled, parallel group study in a pediatric outpatient population (ages 6 to 17) (Study OCD-5). Sertraline hydrochloride (N=92) was initiated at doses of either 25 mg/day (pediatric patients ages 6 to 12) or 50 mg/day (adolescents, ages 13 to 17), and then titrated at 3 and 4 day intervals (25 mg incremental dose for pediatric patients ages 6 to 12) or 1 week intervals (50 mg incremental dose adolescents ages 13 to 17) over the next four weeks to a maximum dose of 200 mg/day, as tolerated. The mean dose for completers was 178 mg/day. Dosing was once a day in the morning or evening. Patients in this study had moderate to severe OCD (DSM-III-R) with mean baseline ratings on the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) total score of 22. Patients receiving sertraline hydrochloride experienced a mean reduction of approximately 7 units on the CY-BOCS total score which was statistically significantly greater than the 3 unit reduction for placebo patients (n=95). Analyses for age and gender effects on outcome did not suggest any differential responsiveness on the basis of age or sex.
