Baseline and 2- to 3-year follow-up characteristics of placebo-washout responders from the nortriptyline study of depressed 6- to 12-year-olds.

Data are presented on the baseline characteristics and 2- to 3-year follow-up assessments of placebo-washout responders (PWRs) from a previously reported pharmacokinetically designed double-blind placebo-controlled trial of nortriptyline for major depressive disorder in 6- to 12-year-olds. Eleven of the 12 PWRs consented to participate in the follow-up study. At baseline, the only significant difference between the PWRs and the non-PWR subjects was that more females were PWRs. Notably, there were no significant differences with respect to severity, chronicity, age of onset, or comorbid psychopathology. The follow-up assessments showed that the rate of relapse to major depressive disorder and the rate of development of bipolarity were not significantly different for PWRs compared with non-PWRs. The authors discuss these findings vis-à-vis the adult literature and provide recommendations for the use of placebo-washout phases in future double-blind, placebo-controlled psychopharmacology trials in children.
