Tiotropium Drug Information

Maintenance Treatment of COPD STIOLTO RESPIMAT is a combination of tiotropium bromide and olodaterol indicated for long-term, once-daily maintenance treatment of patients with chronic obstructive pulmonary disease (COPD), including chronic bronchitis and/or emphysema. Important Limitations of Use STIOLTO RESPIMAT is not indicated to treat acute deteriorations of COPD. STIOLTO RESPIMAT is not indicated to treat asthma.

The safety and effectiveness of STIOLTO RESPIMAT in asthma have not been established.

Recommended Dosage

The recommended dosage of STIOLTO RESPIMAT is two inhalations once-daily at the same time of the day. Do not use STIOLTO RESPIMAT more than two inhalations every 24 hours.

Administration Information

For oral inhalation only. Prior to first use, the STIOLTO RESPIMAT cartridge is inserted into the STIOLTO RESPIMAT inhaler and the unit is primed. When using the unit for the first time, patients are to actuate the inhaler toward the ground until an aerosol cloud is visible and then repeat the process three more times.

The unit is then considered primed and ready for use. If not used for more than 3 days, patients are to actuate the inhaler once to prepare the inhaler for use. If not used for more than 21 days, patients are to actuate the inhaler until an aerosol cloud is visible and then repeat the process three more times to prepare the inhaler for use.

No dosage adjustment is required for geriatric, hepatically-impaired, or renally-impaired patients. However, patients with moderate to severe renal impairment given STIOLTO RESPIMAT should be monitored closely for anticholinergic effects.

Clinical Trials Experience in Chronic Obstructive Pulmonary Disease Because clinical trials are conducted under widely varying conditions, the incidence of adverse reactions observed in the clinical trials of a drug cannot be directly compared to the incidences in the clinical trials of another drug and may not reflect the incidences observed in practice. The clinical program for STIOLTO RESPIMAT included 7,151 subjects with COPD in two 52-week active-controlled trials, one 12-week placebo-controlled trial, three 6-week placebo-controlled cross-over trials, and four additional trials of shorter duration. A total of 1,988 subjects received at least 1 dose of STIOLTO RESPIMAT.

Adverse reactions observed in the ≤12-week trials were consistent with those observed in the 52-week trials, which formed the primary safety database. The primary safety database consisted of pooled data from the two 52-week double-blind, active-controlled, parallel group confirmatory clinical trials (Trials 1 and 2). Of these patients, 1,029 were treated with STIOLTO RESPIMAT once daily.

In these two trials, tiotropium 5 mcg and olodaterol 5 mcg were included as active control arms and no placebo was used. The adverse reaction most commonly leading to discontinuation was worsening COPD. The most common serious adverse reactions were COPD exacerbation and pneumonia.

Table 1 shows all adverse drug reactions that occurred with an incidence of >3% in the STIOLTO RESPIMAT treatment group and a higher incidence rate than the active comparator groups listed. Table 1 Number and frequency of adverse drug reactions greater than 3% (and higher than any of the comparators tiotropium and/or olodaterol) in COPD patients exposed to STIOLTO RESPIMAT: Pooled data from the two 52-week, double-blind, active-controlled clinical trials in COPD patients 40 years of age and older 37 19 35 Other adverse drug reactions in patients receiving STIOLTO RESPIMAT that occurred in ≤3% of patients in clinical studies are listed below: Metabolism and nutrition disorders: dehydration Nervous system disorders: dizziness, insomnia Eye disorders: glaucoma, intraocular pressure increased, vision blurred Cardiac/vascular disorders: atrial fibrillation, palpitations, supraventricular tachycardia, tachycardia, hypertension Respiratory, thoracic, and mediastinal disorders: epistaxis, pharyngitis, dysphonia, bronchospasm, laryngitis, sinusitis Gastrointestinal disorders: dry mouth, constipation, oropharyngeal candidiasis, dysphagia, gastroesophageal reflux disease, gingivitis, glossitis, stomatitis, intestinal obstruction including ileus paralytic Skin and subcutaneous disorders: rash, pruritus, angioneurotic edema, urticaria, skin infection, and skin ulcer, dry skin, hypersensitivity (including immediate reactions) Musculoskeletal and connective tissue disorders: arthralgia, joint swelling Renal and urinary disorders: urinary retention, dysuria, and urinary tract infection COPD Exacerbation Reduction Trial In a one year trial (Trial 5) of 7,880 patients to compare rates of COPD exacerbations, 3,939 patients were treated with STIOLTO RESPIMAT and 3,941 patients were treated with tiotropium 5 mcg inhalation spray. The safety profile of STIOLTO RESPIMAT was similar to that of tiotropium 5 mcg inhalation spray and consistent with that documented in the STIOLTO RESPIMAT primary safety database.

Adrenergic Drugs

If additional adrenergic drugs are to be administered by any route, they should be used with caution because the sympathetic effects of olodaterol, one component of STIOLTO RESPIMAT, may be potentiated.

Sympathomimetics, Xanthine Derivatives, Steroids, or Diuretics Tiotropium has been used concomitantly with short-acting and long-acting sympathomimetic (beta-agonists) bronchodilators, methylxanthines, and oral and inhaled steroids, without increases in adverse reactions. Concomitant treatment with xanthine derivatives, steroids, or diuretics may potentiate any hypokalemic effect of olodaterol.

Non-Potassium Sparing Diuretics The ECG changes and/or hypokalemia that may result from the administration of non-potassium sparing diuretics (such as loop or thiazide diuretics) can be acutely worsened by beta-agonists, especially when the recommended dosage of the beta-agonist is exceeded. Although the clinical significance of these effects is not known, caution is advised in the co-administration of STIOLTO RESPIMAT with non-potassium sparing diuretics.

Monoamine Oxidase Inhibitors, Tricyclic Antidepressants, QTc Prolonging Drugs STIOLTO RESPIMAT, as with other drugs containing beta 2 -agonists, should be administered with extreme caution to patients being treated with monoamine oxidase inhibitors or tricyclic antidepressants or other drugs known to prolong the QTc interval because the action of adrenergic agonists on the cardiovascular system may be potentiated by these agents. Drugs that are known to prolong the QTc interval may be associated with an increased risk of ventricular arrhythmias.

Beta-Blockers

Beta-adrenergic receptor antagonists (beta-blockers) and the olodaterol component of STIOLTO RESPIMAT may interfere with the effect of each other when administered concurrently. Beta-blockers not only block the therapeutic effects of beta-agonists, but may produce severe bronchospasm in COPD patients. Therefore, patients with COPD should not normally be treated with beta-blockers.

However, under certain circumstances, e.g., as prophylaxis after myocardial infarction, there may be no acceptable alternatives to the use of beta-blockers in patients with COPD. In this setting, cardioselective beta-blockers could be considered, although they should be administered with caution.

Anticholinergics There is potential for an additive interaction with concomitantly used anticholinergic medications. Therefore, avoid co-administration of STIOLTO RESPIMAT with other anticholinergic-containing drugs as this may lead to an increase in anticholinergic adverse effects.

Inhibitors of Cytochrome P450 and P-gp Efflux Transporter In a drug interaction study using the strong dual CYP and P-gp inhibitor ketoconazole, a 1.7-fold increase of olodaterol maximum plasma concentrations and AUC was observed. Olodaterol was evaluated in clinical trials for up to one year at doses up to twice the recommended therapeutic dosage. No dosage adjustment of STIOLTO RESPIMAT is necessary.

Pregnancy Risk Summary There are no adequate and well-controlled clinical studies with STIOLTO RESPIMAT or its individual components, tiotropium bromide and olodaterol, in pregnant women to inform of drug-associated risk of adverse pregnancy-related outcomes. Animal reproduction studies were conducted with the individual components of STIOLTO RESPIMAT, tiotropium bromide and olodaterol. There are clinical considerations with the use of STIOLTO RESPIMAT in pregnant women (see Clinical Considerations ).

STIOLTO RESPIMAT should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Based on animal reproduction studies, no structural abnormalities were observed when tiotropium was administered by inhalation to pregnant rats and rabbits during the period of organogenesis at doses 790 and 8 times, respectively, the maximum recommended human daily inhalation dose (MRHDID). Increased post-implantation loss was observed in rats and rabbits administered tiotropium at maternally toxic doses 430 times and 40 times the MRHDID, respectively (see Data ).

Based on animal studies, olodaterol was not teratogenic when administered to pregnant rats or rabbits during organogenesis at inhalation doses of approximately 2,731 or 1,353 times the MRHDID (on an AUC basis), in rats or rabbits, respectively (see Data ). The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss or other adverse outcomes.

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is respectively. Clinical Considerations Labor and Delivery There are no adequate and well-controlled human studies that have investigated the effects of STIOLTO RESPIMAT on preterm labor or labor at term. Because of the potential for beta-agonist interference with uterine contractility, use of STIOLTO RESPIMAT during labor should be restricted to those patients in whom the benefits clearly outweigh the risks.

Data Animal Data Animal reproduction studies with the combination of tiotropium and olodaterol are not available; however, studies are available with the individual components. No evidence of structural abnormalities was observed in rats or rabbits. However, in rats, tiotropium caused fetal resorption, litter loss, decreases in the number of live pups at birth and the mean pup weights, and a delay in pup sexual maturation at tiotropium doses of approximately 40 times the MRHDID (on a mcg/m 2 basis at a maternal inhalation dose of 78 mcg/kg/day).

In rabbits, tiotropium caused an increase in post-implantation loss at a tiotropium dose of approximately 430 times the MRHDID (on a mcg/m 2 basis at a maternal inhalation dose of 400 mcg/kg/day). Olodaterol Olodaterol was not teratogenic in rats at inhalation doses approximately 2,731 times the MRHDID (on an AUC basis at a maternal inhalation dose of 1,054 mcg/kg/day). No significant effects occurred in rabbits at inhalation doses approximately 1,353 times the MRHDID in adults (on an AUC basis at a maternal inhalation dose of 974 mcg/kg/day).

Placental transfer of olodaterol was observed in pregnant rats. Olodaterol has been shown to be teratogenic in New Zealand rabbits at inhalation doses approximately 7,130 times the MRHDID in adults (on an AUC basis at a maternal inhalation dose of 2,489 mcg/kg/day). Olodaterol exhibited the following fetal toxicities: enlarged or small heart atria or ventricles, eye abnormalities, and split or distorted sternum.

Pediatric Use COPD does not normally occur in children. The safety and effectiveness of STIOLTO RESPIMAT in the pediatric population has not been established.

Use of a LABA, including STIOLTO RESPIMAT, without an inhaled corticosteroid is contraindicated in patients with asthma. STIOLTO RESPIMAT is not indicated for the treatment of asthma. STIOLTO RESPIMAT is contraindicated in patients with a hypersensitivity to tiotropium, ipratropium, olodaterol, or any component of this product.

In clinical trials and postmarketing experience with tiotropium, immediate hypersensitivity reactions, including angioedema (including swelling of the lips, tongue, or throat), itching, or rash have been reported. Hypersensitivity reactions were also reported in clinical trials with STIOLTO RESPIMAT.

STIOLTO RESPIMAT contains both tiotropium bromide and olodaterol; therefore, the risks associated with overdosage for the individual components described below apply to STIOLTO RESPIMAT. Tiotropium High doses of tiotropium may lead to anticholinergic signs and symptoms. However, there were no systemic anticholinergic adverse effects following a single inhaled dose of up to 282 mcg tiotropium in 6 healthy volunteers.

In a study of 12 healthy volunteers, bilateral conjunctivitis and dry mouth were seen following repeated once-daily inhalation of 141 mcg of tiotropium. Dry mouth/throat and dry nasal mucosa occurred in a dose-dependent manner, were observed following 14-day dosing of up to 40 mcg tiotropium bromide inhalation solution in healthy subjects. Olodaterol The expected signs and symptoms with overdosage of olodaterol are those of excessive beta-adrenergic stimulation and occurrence or exaggeration of any of the signs and symptoms, e.g., myocardial ischemia, angina pectoris, hypertension or hypotension, tachycardia, arrhythmias, palpitations, dizziness, nervousness, insomnia, anxiety, headache, tremor, dry mouth, muscle spasms, nausea, fatigue, malaise, hypokalemia, hyperglycemia, and metabolic acidosis.

As with all inhaled sympathomimetic medications, cardiac arrest and even death may be associated with an overdose of olodaterol. Treatment of overdosage consists of discontinuation of STIOLTO RESPIMAT together with institution of appropriate symptomatic and supportive therapy. The judicious use of a cardioselective beta-receptor blocker may be considered, bearing in mind that such medication can produce bronchospasm.

There is insufficient evidence to determine if dialysis is beneficial for overdosage of STIOLTO RESPIMAT. Cardiac monitoring is recommended in cases of overdosage.
