Clinical Trial Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The data described below are from clinical trials in which REMERON/REMERONSolTab was administered to 2796 patients in phase 2 and 3 clinical studies. The trials consisted of double-blind controlled and open-label studies, inpatient and outpatient studies, fixed dose, and titration studies.

Adverse Reactions Leading To Discontinuation Of Treatment

Approximately 16% of the 453 patients who received REMERON in U.S. 6-week placebo-controlled clinical trials discontinued treatment due to an adverse reaction, compared to 7% of the 361 placebo-treated patients in those studies. The most common reactions leading to discontinuation (≥1% and at a rate at least twice that of placebo) are included in Table 2.

Common Adverse Reactions

The most common adverse reactions (≥5% and twice placebo) associated with the use of REMERON are listed in Table 3.

Increased Appetite17%2%
Weight Gain12%2%

Table 4 enumerates adverse reactions that occurred in ≥1% of REMERON-treated patients, and were more frequent than the placebo-treated patients, who participated in 6-week, U.S. placebo-controlled trials in which patients were dosed in a range of 5 to 60 mg/day. This table shows the percentage of patients in each group who had at least 1 episode of an adverse reaction at some time during their treatment.

ECG Changes

The electrocardiograms for 338 patients who received REMERON and 261 patients who received placebo in 6-week, placebo-controlled trials were analyzed.
