The following clinically significant adverse reaction is described elsewhere in the labeling:

  • Urinary retention [see WARNINGS AND PRECAUTIONS]

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.

The safety of GEMTESA was evaluated in a 12-week, double-blind, placebo-and active-controlled study (Study 3003) in patients with OAB [see Clinical Studies]. A total of 545 patients received GEMTESA. The majority of the patients were Caucasian (78%) and female (85%) with a mean age of 60 years (range 18 to 93 years).

Adverse reactions that were reported in Study 3003 at an incidence greater than placebo and in ≥2% of patients treated with GEMTESA are listed in Table 1.

Other adverse reactions reported in <2% of patients treated with GEMTESA included:

Gastrointestinal disorders: dry mouth, constipation

Investigations: residual urine volume increased

Renal and urinary disorders: urinary retention

Vascular disorders: hot flush

GEMTESA was also evaluated for long-term safety in an extension study (Study 3004) in 505 patients who completed the 12-week study (Study 3003). Of the 273 patients who received GEMTESA 75 mg once daily in the extension study, 181 patients were treated for a total of one year.

Adverse reactions reported in ≥2% of patients treated with GEMTESA 75 mg for up to 52 weeks in the longterm extension study, and not already listed above, were urinary tract infection (6.6%) and bronchitis (2.9%).

Postmarketing Experience

The following adverse reactions have been identified during post-approval use of vibegron. 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 adverse events have been reported in association with vibegron use in worldwide postmarketing experience:

Urologic disorders: urinary retention

Skin and subcutaneous tissue disorders: pruritus, rash, drug eruption, eczema

Gastrointestinal disorders: constipation
