Major Depressive Disorder Clinical Trial
Official title:
A Multi-Center, Double Blind, Randomized, Placebo-Controlled, Parallel Group, Flexible Dose Titration, Add-On Study of Mecamylamine 5.0 to 10 mg, in the Treatment of Major Depressive Disorder With Subjects Who Are Partial or Non- Responders to Citalopram Therapy.
Depressed patients will receive 6 weeks of citaloprma (20-40mg) therapy. Subjects who have an inadequate response (partial or non-responder) will be randomized to receive either mecamylamine (5-10mg) or placebo added to their citalopram for a further 8 weeks.
This is a double blind, randomized, placebo controlled, parallel group, flexible dose
titration, add-on study. Male or female subjects aged 18-70 years suffering from Major
Depressive Disorder according to DSM-IV, with a HAMD-17 score greater than 21 and a
CGI-Severity of Illness score greater or equal to 4, will be started on open labeled
citalopram treatment. The dose of citalopram may be increased form 20mg to 40mg over a six
week period, depending on investigator assessment of tolerability and efficacy. At the end
of this treatment, subjects with a HAMD-17 score greater or equal to 14 and a CGI-Severity
of Illness score greater or equal to 4 will be considered as partial or non-responders and
will be entered into the double blind phase of the study. Subjects will be randomized to
either mecamylamine or placebo for a further 8 weeks. Citalopram medication will remain
constant while mecamylamine (or placebo) can be increased from 5.0 to 7.5 to 10.0mg based on
investigator assessment of tolerability and efficacy.
Plasma samples for citalopram assay will be collected at the start and end of the double
blind phase to exclude any mecamylamine effect being due to a drug:drug interaction.
Approximately 500 subjects will be entered into the open-label phase of the study and
approximately 160 into the double blind phase. The study will be conducted in India and the
USA.
