The following adverse reactions are discussed in more detail in other sections of the labeling.

Hypertension [see Warnings and Precautions ( 5.1 )] Urinary Retention [see Warnings and Precautions ( 5.2 )] Angioedema [see Warnings and Precautions ( 5.3 )] 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 clinical practice.

Mirabegron Extended-Release Tablets Monotherapy for Adult OAB In three, 12-week, double-blind, placebo-controlled, safety and efficacy studies in patients with OAB (Studies 1, 2, and 3), mirabegron extended-release tablets were evaluated for safety in 2736 patients [see Clinical Studies ( 14.1 )] .

Study 1 also included an active control.

For the combined Studies 1, 2, and 3, 432 patients received mirabegron extended-release tablets 25 mg, 1375 received mirabegron extended-release tablets 50 mg, and 929 received mirabegron extended-release tablets 100 mg once daily.

In these studies, the majority of the patients were Caucasian (94%) and female (72%) with a mean age of 59 years (range 18 to 95 years).

Mirabegron extended-release tablets were also evaluated for safety in 1632 patients who received mirabegron extended-release tablets 50 mg once daily (n=812 patients) or mirabegron extended-release tablets 100 mg (n=820 patients) in a 1-year, randomized, fixed-dose, double-blind, active-controlled, safety study in patients with OAB (Study 4).

Of these patients, 731 received mirabegron extended-release tablets in a previous 12-week study.

In Study 4, 1385 patients received mirabegron extended-release tablets continuously for at least 6 months, 1311 patients received mirabegron extended-release tablets for at least 9 months, and 564 patients received mirabegron extended-release tablets for at least 1 year.

The most frequent adverse events (0.2%) leading to discontinuation in Studies 1, 2, and 3 for the 25 mg or 50 mg dose were nausea, headache, hypertension, diarrhea, constipation, dizziness, and tachycardia.

Atrial fibrillation (0.2%) and prostate cancer (0.1%) were reported as serious adverse events by more than 1 patient and at a rate greater than placebo.

Table 8 lists the adverse reactions, derived from all adverse events, that were reported in Studies 1, 2, and 3 at an incidence greater than placebo and in 1% or more of patients treated with mirabegron extended-release tablets 25 mg or 50 mg once daily for up to 12 weeks.

The most commonly reported adverse reactions (greater than 2% of mirabegron extended-release tablets patients and greater than placebo) were hypertension, nasopharyngitis, urinary tract infection, and headache.

The most commonly reported adverse reactions (>3% of mirabegron extended-release tablets patients) were hypertension, urinary tract infection, headache, and nasopharyngitis.

Serious adverse events reported by at least 2 patients and exceeding active control included cerebrovascular accident (0.4%) and osteoarthritis (0.2%).

Serum ALT/AST increased from baseline by greater than 10-fold in 2 patients (0.3%) taking mirabegron extended-release tablets 50 mg; and these markers subsequently returned to baseline while both patients continued mirabegron extended-release tablets.

In Study 4, serious adverse events of neoplasm were reported by 0.1%, 1.3%, and 0.5% of patients treated with mirabegron extended-release tablets 50 mg, mirabegron extended-release tablets 100 mg, and active control once daily, respectively.

Neoplasms reported by 2 patients treated with mirabegron extended-release tablets 100 mg included breast cancer, lung neoplasm malignant, and prostate cancer.

A causal relationship between mirabegron and these reported neoplasms has not been established.

In a separate clinical study in Japan, a single case was reported as Stevens-Johnson syndrome with increased serum ALT, AST, and bilirubin in a patient taking mirabegron extended-release tablets 100 mg as well as an herbal medication (Kyufu Gold).

6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of mirabegron extended-release tablets.

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.

The following events have been reported in association with mirabegron use in worldwide postmarketing experience: Cardiac disorders: Atrial fibrillation Gastrointestinal disorders: Nausea, constipation, diarrhea Nervous system disorders: Dizziness, headache There have been postmarketing reports of confusion, hallucinations, insomnia, and anxiety in patients taking mirabegron.

The majority of these patients had pre-existing medical conditions or concomitant medications that may cause confusion, hallucinations, insomnia, and anxiety.

A causal relationship between mirabegron and these disorders has not been established.

Skin and subcutaneous tissue disorders: Angioedema of the face, lips, tongue, and larynx, with or without respiratory symptoms [see Warnings and Precautions ( 5.3 )] ; pruritus Renal and urinary disorders: Urinary retention [see Warnings and Precautions ( 5.2 )]
