6.1 Clinical Trials 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.
Adult Ulcerative Colitis During clinical development, 259 adult patients with active ulcerative colitis were exposed to 6.75 g/day balsalazide disodium in 4 controlled trials.
In the 4 controlled clinical trials patients receiving a balsalazide disodium dose of 6.75 g/day most frequently reported the following adverse reactions: headache (8%), abdominal pain (6%), diarrhea (5%), nausea (5%), vomiting (4%), respiratory infection (4%), and arthralgia (4%).
Withdrawal from therapy due to adverse reactions was comparable among patients on balsalazide disodium and placebo.
Adverse reactions reported by 1% or more of patients who participated in the 4 well-controlled, Phase 3 trials are presented by treatment group (Table 1).
The number of placebo patients (35), however, is too small for valid comparisons.
Some adverse reactions, such as abdominal pain, fatigue, and nausea were reported more frequently in women than in men.
Abdominal pain, rectal bleeding, and anemia can be part of the clinical presentation of ulcerative colitis.
Table 1: Adverse Reactions Occurring in ≥1% of Adult balsalazide disodium Patients in Controlled Trials Adverse reactions occurring in at least 1% of balsalazide disodium patients which were less frequent than placebo for the same adverse reaction were not included in the table.

One patient who received balsalazide disodium 6.75 g/day and 3 patients who received balsalazide disodium 2.25 g/day discontinued treatment because of adverse reactions.
In addition, 2 patients in each dose group discontinued because of a lack of efficacy.
Adverse reactions reported by 3% or more of pediatric patients within either treatment group in the Phase 3 trial are presented in Table 2.

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
