About the Targacept and AstraZeneca CollaborationIn December 2009, AstraZeneca and Targacept signed a collaboration and license agreement for the global development and commercialization of TC-5214. The initial goal for the collaboration was to develop TC-5214 as an adjunct treatment for MDD in patients with an inadequate response to a selective serotonin reuptake inhibitor (SSRI) or serotonin/norepinephrine reuptake inhibitor (SNRI). About MDD MDD is characterized by one or more major depressive episodes without a history of manic, mixed or hypomanic episodes. The essential feature of a major depressive episode is a period of at least two weeks during which there is depressed mood or the loss of interest or pleasure in nearly all activities. In the large-scale STAR*D study sponsored by the US National Institute of Mental Health between 2001 and 2006, approximately 63 percent of patients with MDD did not achieve study-defined remission with first-line treatment with the SSRI citalopram hydrobromide. About the RENAISSANCE Program (TC-5214) The RENAISSANCE Program consisted of five randomized, double blind, placebo controlled Phase 3 studies. In RENAISSANCE study 4, a total of 2,407 patients with MDD were screened at 126 sites in the United States and India. Of the patients screened, 1,335 initially received one of seven SSRIs or SNRIs on an open label basis for eight weeks to determine the extent of therapeutic response. At the end of the eight weeks, 641 patients who did not respond adequately, based on predefined criteria, were randomized into the double blind phase of the study and received either a fixed dose of TC-5214 or placebo while continuing the SSRI or SNRI therapy for an additional eight weeks. The dosages of TC-5214 tested in the study were 0.5 mg, 2 mg and 4 mg BID (twice daily). In RENAISSANCE study 5, a total of 1,566 patients with MDD were screened at 155 sites in Argentina, Brazil, Bulgaria, Chile, Colombia, France, Germany, Poland, Romania, Russia, Serbia, Slovakia, South Africa, Spain, and Ukraine. Of the patients screened, 1,285 initially received one of seven SSRIs or SNRIs on an open label basis for eight weeks to determine the extent of therapeutic response. At the end of the eight weeks, 696 patients who did not respond adequately, based on predefined criteria, were randomized into the double blind phase of the study and received either a fixed dose of TC-5214 or placebo while continuing the SSRI or SNRI therapy for an additional eight weeks. The dosages of TC-5214 tested in the study were 0.1 mg, 1 mg and 4 mg BID.
In RENAISSANCE study 7, a total of 1,934 patients with MDD were screened at 121 sites in the United States. Of the patients screened, 808 patients in this flexible dose trial received TC-5214 (range of 1-4mg BID) or placebo, plus one of seven SSRIs or SNRIs, for up to one year.About the Montgomery-Asberg Depression Rating Scale The Montgomery-Asberg Depression Rating Scale (MADRS) is a commonly used 10-item questionnaire that psychiatrists employ to measure the severity of depressive episodes in patients with mood disorders.
