SIDE EFFECTS

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, the 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.

The data described below reflect exposure to SANCTURA XR® capsules in 578 patients for 12 weeks in two Phase 3 double-blind, placebo controlled trials (n=l 165). These studies included overactive bladder patients of ages 21 to 90 years, of which 86% were female and 85% were Caucasian. Patients received 60 mg daily doses of SANCTURA XR®. Patients in these studies were eligible to continue treatment with SANCTURA XR® 60 mg for up to one year. From both these controlled trials combined, 769 and 238 patients received treatment with SANCTURA XR® for at least 24 and 52 weeks, respectively.

There were 157 (27.2%) SANCTURA XR® patients and 98 (16.7%) placebo patients who experienced one or more double-blind treatment-emergent adverse events (TEAEs) that were assessed by the investigator as at least possibly related to study medication. The most common TEAEs were dry mouth and constipation which, when reported, commonly occurred early in treatment (often within the first week). In the two Phase 3 studies, constipation, dry mouth, and urinary retention led to discontinuation in 1%, 0.7%, and 0.5% of patients treated with SANCTURA XR® 60 mg daily, respectively. In the placebo group, there were no discontinuations due to dry mouth or urinary retention and one due to constipation.

The incidence of serious adverse events was similar among patients receiving SANCTURA XR® and patients receiving placebo. No treatment-emergent serious adverse events in either treatment group were judged by the investigators as being possibly related to the study medication.

Table 1 lists those treatment emergent adverse events from the trials that were assessed by the investigator as possibly related to study medication, reported in at least 1% of SANCTURA XR® patients, and were more common for the SANCTURA XR® group than for placebo.

Dry eye 1 (0.2) 9(1.6)
Flatulence 3 (0.5) 9(1.6)
Nausea 2 (0.3) 8(1.4)

Dyspepsia 4(0.7) 7(1.2)
Urinary tract infection 5 (0.9) 7(1.2)
Constipation aggravated 3 (0.5) 7(1.2)
Abdominal distension 2 (0.3) 6(1.0)
Nasal dryness 0 (0.0) 6(1.0)

 

Additional adverse events reported in less than 1% of SANCTURA XR® treated patients and more common for SANCTURA XR® than placebo, judged by the investigator at least possibly related to treatment were: vision blurred, feces hard, back pain, somnolence, urinary retention, and dry skin.

Table 2 lists all treatment-emergent adverse events for the trials reported in at least 2% of all SANCTURA XR® patients and more common for the SANCTURA XR® group than for placebo without regard to the investigator’s judgment on drug relatedness.

Table 2: Incidence of treatment-emergent adverse events reported in at least 2% of patients regardless of reported relationship to treatment and more common for the SANCTURA XR® group than for placebo

MedDRA Preferred term Number of patients (%)
Placebo
N=587

N=578
Dry mouth 22 (3.7) 64(11.1)
Constipation 10(1.7) 52 (9.0)
Urinary tract infection 29 (4.9) 42 (7.3)
Nasopharyngitis 10(1.7) 17 (2.9)
Influenza 9(1.5) 13 (2.2)

 

Additional adverse events reported in less than 2% of SANCTURA XR® treated patients and twice as frequent for SANCTURA XR® compared to placebo, regardless of reported relationship to treatment were: tachycardia, dry eyes, abdominal pain, dyspepsia, abdominal distension, constipation aggravated, nasal dryness, and rash.

In the open-label treatment phase, the most common TEAEs reported in the 769 patients with at least 6 months exposure to SANCTURA XR® were: constipation, and dry mouth. Urinary tract infection and rash was also reported in several patients, including one of each judged by the investigator to be possibly related to treatment. Several adverse events were reported as severe in the open-label treatment phase, including one urinary tract infection, two urinary retention events, and one aggravated constipation.

Post-marketing Experience

The following adverse reactions have been identified during post-approval use of trospium chloride. 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.

Gastrointestinal – gastritis; Cardiovascular – palpitations, supraventricular tachycardia, chest pain, syncope, “hypertensive crisis”; Immunological – Stevens-Johnson syndrome, anaphylactic reaction, angioedema; Nervous System – dizziness, confusion, vision abnormal, hallucinations, somnolence, and delirium; Musculoskeletal – rhabdomyolysis; General – rash.
