Table 8.3.1.2, supplied by the sponsor, summarizes reasons for premature discontinuation among patients who were assigned to receive treatment under protocol 208. Because 67 patients assigned to receive treatment dropped out between point of randomization and first ingestion of medication, the total number of subjects in this table is larger by 67 than the number of subjects in the demographics table of section 5.1.2.

Adverse Events Associated with Dropout
As
noted in Table 8.3.1, 10.2% of the bupropion sustained-release-assigned patients
in the integrated Phase 2-3 safety database withdrew because of an adverse
experience, as compared with 5.7% of placebo-assigned patients.
The
following table lists all those categories of adverse experiences leading to
dropout that were associated with at least 0.3% of the 693 subjects who were
randomly assigned to receive bupropion sustained-release in protocols 203 and
205 who received some of the medication.
Placebo rates for the same adverse experiences are shown for
comparison. In those cases where the
individual investigators did not designate a specific adverse event resulting
in discontinuation, this reviewer assigned the specific adverse event or events
based on the case report listings or narrative case summaries.
