Introduction to Striverdi Respimat
Striverdi Respimat, developed by Boehringer Ingelheim Pharmaceuticals, is an inhalation spray indicated for the maintenance treatment of chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema. The active component, olodaterol, is a long-acting beta2-adrenergic agonist (LABA) that provides 24-hour bronchodilatory activity with once-daily dosing[1][2][5].
Clinical Trials Overview
The FDA approval of Striverdi Respimat was based on the results of a comprehensive clinical trial program. Here are the key points from these trials:
Phase III Clinical Trials
- The clinical development program included seven dose-ranging trials and eight confirmatory trials. Four of the confirmatory trials were 6-week cross-over trials, and four were 48-week parallel group trials[3][4][5].
- The pivotal studies involved 3,104 COPD patients aged 40 years or older, with a smoking history of at least 10 years and significant pulmonary impairment. Patients were randomized to receive either Striverdi Respimat 5µg, 10µg, or a placebo once daily[1][5].
- The 48-week trials demonstrated significant improvements in lung function, including peak expiratory flow rate (PEFR), compared to the placebo. The drug showed a bronchodilatory effect within five minutes of the first dose[1][5].
Safety and Efficacy
- The primary safety database from the 48-week trials showed that 72% of patients exposed to Striverdi Respimat reported an adverse reaction, compared to 71% in the placebo group. Common adverse reactions included nasopharyngitis, hypertension, dizziness, rash, and arthralgia[3][4].
- Serious adverse reactions were COPD exacerbation, pneumonia, and atrial fibrillation. The proportion of patients who discontinued due to an adverse reaction was 7.2% for Striverdi Respimat-treated patients compared to 8.8% for placebo-treated patients[3][4].
Dosing and Efficacy
- The 5µg dose of Striverdi Respimat showed significant improvements in lung function and quality of life measures, such as the St. George's Respiratory Questionnaire (SGRQ) total score. There was no additional benefit observed with the 10µg dose over the 5µg dose[1][5].
Market Analysis
Market Presence
- Striverdi Respimat was approved by the FDA in August 2014 and is now available by prescription in pharmacies across the United States[2].
- Boehringer Ingelheim, with its strong respiratory heritage, has positioned Striverdi Respimat as a valuable addition to the treatment options for COPD, a condition affecting approximately 15 million Americans[2].
Competitive Landscape
- The COPD treatment market is competitive, with other notable treatments like Spiriva (tiotropium bromide), also developed by Boehringer Ingelheim. Spiriva has been a leading maintenance treatment for COPD worldwide since its introduction[1].
- Striverdi Respimat differentiates itself with its once-daily dosing regimen and the use of the Respimat inhaler, which is designed to deliver a consistent dose of medication[2].
Patient and Provider Acceptance
- The introduction of Striverdi Respimat has been welcomed by both healthcare providers and patients, offering an additional treatment option that can improve lung function and quality of life for those with COPD[2].
Market Projections
Growth Potential
- Given the prevalence of COPD and the ongoing need for effective maintenance treatments, Striverdi Respimat is expected to see significant growth in the market. The drug's efficacy and convenience of once-daily dosing are key factors driving its adoption[2].
Market Share
- As part of Boehringer Ingelheim's robust lung health portfolio, Striverdi Respimat is anticipated to capture a substantial share of the COPD treatment market. The company's established presence and reputation in respiratory care will likely contribute to the drug's market success[1][2].
Future Developments
- Continuous monitoring and post-authorization activities, as outlined in the Risk Management Plan (RMP) submitted to regulatory bodies, will ensure that any safety issues are promptly addressed. This proactive approach will help maintain and potentially increase market confidence in Striverdi Respimat[5].

FAQs
Q: What is Striverdi Respimat used for?
A: Striverdi Respimat is used for the maintenance treatment of chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema.
Q: How does Striverdi Respimat work?
A: Striverdi Respimat contains olodaterol, a long-acting beta2-adrenergic agonist (LABA), which binds to beta2-adrenoceptors, leading to bronchodilation by relaxing airway smooth muscle cells.
Q: What were the key findings from the clinical trials of Striverdi Respimat?
A: Clinical trials showed significant improvements in lung function, including peak expiratory flow rate (PEFR), and quality of life measures compared to placebo. The 5µg dose was found to be effective without additional benefit from the 10µg dose.
Q: What are the common adverse reactions associated with Striverdi Respimat?
A: Common adverse reactions include nasopharyngitis, hypertension, dizziness, rash, and arthralgia. Serious adverse reactions include COPD exacerbation, pneumonia, and atrial fibrillation.
Q: Is Striverdi Respimat indicated for treating asthma?
A: No, Striverdi Respimat is not indicated for treating asthma or acute deteriorations of COPD.
