BI launches COPD drug Striverdi, olodaterol in UK and Ireland

BI-1744-CL (hydrochloride) marketed as drug

Olodaterol (trade name Striverdi) is a long acting beta-adrenoceptor agonist used as an inhalation for treating patients with chronic obstructive pulmonary disease (COPD), manufactured by Boehringer-Ingelheim.[1]

see..........           ......... synfacts

Olodaterol is a potent agonist of the human β2-adrenoceptor with a high β12 selectivity. Its crystalline hydrochloride salt is suitable for inhalation and is currently undergoing clinical trials in man for the treatment of asthma. Oloda­terol has a duration of action that exceeds 24 hours in two preclinical animal models of bronchoprotection and it has a better safety margin compared with formoterol.

Boehringer Ingelheim has launched a new chronic obstructive pulmonary disease drug, Striverdi in the UK and Ireland.
Striverdi (olodaterol) is the second molecule to be licenced for delivery via the company’s Respimat Soft Mist inhaler, following the COPD blockbuster Spiriva (tiotropium). The drug was approved in Europe in November based on results from a Phase III programme that included more than 3,000 patients with moderate to very severe disease.

Olodaterol hydrochloride is a drug candidate originated by Boehringer Ingelheim. The product, delivered once-daily by the Respimat Soft Mist Inhaler, was first launched in Denmark and the Netherlands in March 2014 for the use as maintenance treatment of chronic obstructive pulmonary disease (COPD), including chronic bronchitis and/or emphysema. In 2013, approval was obtained in Russia and Canada for the same indication, and in the U.S, the product was recommended for approval. Phase III clinical trials for the treatment of COPD are ongoing in Japan.

Medical uses

Olodaterol is a once-daily maintenance bronchodilator treatment of airflow obstruction in patients with COPD including chronic bronchitis and/or emphysema, and is administered in an inhaler called Respimat Soft Mist Inhaler.[2][3][4][5][6][7]
As of December 2013, olodaterol is not approved for the treatment of asthma. Olodaterol monotherapy was previously evaluated in four Phase 2 studies in asthma patients. However, currently there are no Phase 3 studies planned for olodaterol monotherapy in patients with asthma.
In late January 2013, Olodaterol CAS# 868049-49-4 was the focus of an FDA committee reviewing data for the drug’s approval as a once-daily maintenance bronchodilator to treat chronic obstructive pulmonary disease (COPD), as well as chronic bronchitis and emphysema. The FDA Pulmonary-Allergy Drugs Advisory Committee recommended that the clinical data from the Boehringer Ingelheim Phase III studies be included in their NDA.
Also known as the trade name Striverdi Respimat, Olodaterol is efficacious as a long-acting beta-agonist, which patients self-administer via an easy to use metered dose inhaler. While early statistics from clinical trials of Olodaterol were encouraging, a new set of data was released earlier this week, which only further solidified the effectual and tolerable benefits of this COPD drug.
On September 10, 2013 results from two Phase 3 studies of Olodaterol revealed additional positive results from this formidable COPD treatment. The conclusion from these two 48 week studies, which included over 3,000 patients, showed sizable and significant improvements in the lung function of patients who were dosed with Olodaterol. Patients in the aforementioned studies were administered either a once a day dosage of Olodaterol via the appropriate metered-dose inhaler or “usual care”. The “usual care” included a variety of treatment options, such as inhaled corticosteroids (not Olodaterol), short and long acting anticholinergics, xanthines and beta agonists, which were short acting. The clinical trial participants who were dosed with Olodaterol displayed a rapid onset of action from this drug, oftentimes within the first five minutes after taking this medication. Additionally, patients dispensed the Olodaterol inhaler were successfully able to maintain optimum lung function for longer than a full 24 hour period. The participants who were given Olodaterol experienced such an obvious clinical improvement in their COPD symptoms, and it quickly became apparent that the “usual care” protocol was lacking in efficacy and reliability.
A staggering 24 million patients in the United States suffer from chronic obstructive pulmonary disease, and this patient population is in need of an effectual, safe and tolerable solution. Olodaterol is shaping up to be that much needed solution. Not only have the results from studies of Olodaterol been encouraging, the studies themselves have actually been forward thinking and wellness centered. Boehringer Ingelheim is the first company to included studies to evaluate exercise tolerance in  patients with COPD, and compare the data to those patients who were dosed with Olodaterol. By including exercise tolerance as an important benchmark in pertinent data for Olodaterol, Boehringer Ingelheim has created a standard for COPD treatment expectations. The impaired lung function for patients with COPD contributes greatly to their inability to exercise and stay healthy. Patients who find treatments and management techniques to combat the lung hyperinflation that develops during exercise have a distinct advantage to attaining overall good health.

Data has demonstrated that Striverdi, a once-daily long-acting beta2 agonist, significantly improved lung function versus placebo and is comparable to improvements shown with the older LABA formoterol. The NHS price for the drug is £26.35 for a 30-day supply.
Boehringer cited Richard Russell at Wexham Park Hospital as saying that the licensing of Stirverdi will be welcomed by clinicians as it provides another option. He added that the trial results showing improvements in lung function “are particularly impressive considering the study design, which allowed participants to continue their usual treatment regimen. This reflects more closely the real-world patient population”.
Significantly, the company is also developing olodaterol in combination with Spiriva, a long-acting muscarinic antagonist. LAMA/LABA combinations provide the convenience of delivering the two major bronchodilator classes.

Adverse effects

Adverse effects generally were rare and mild in clinical studies. Most common, but still affecting no more than 1% of patients, were nasopharyngitis (running nose), dizziness and rash. To judge from the drug's mechanism of action and from experiences with related drugs, hypertension (high blood pressure), tachycardia (fast heartbeat), hypokalaemia (low blood levels of potassium), shaking, etc., might occur in some patients, but these effects have rarely, if at all, been observed in studies.[1]


Based on theoretical considerations, co-application of other beta-adrenoceptor agonists, potassium lowering drugs (e. g. corticoids, many diuretics, and theophylline), tricyclic antidepressants, and monoamine oxidase inhibitors could increase the likelihood of adverse effects to occur. Beta blockers, a group of drugs for the treatment of hypertension (high blood pressure) and various conditions of the heart, could reduce the efficacy of olodaterol.[1] Clinical data on the relevance of such interactions are very limited.


Mechanism of action

Like all beta-adrenoceptor agonists, olodaterol mimics the effect of epinephrine at beta-2 receptors (β₂-receptors) in the lung, which causes the bronchi to relax and reduces their resistance to airflow.[3]
Olodaterol is a nearly full β₂-agonist, having 88% intrinsic activity compared to the gold standard isoprenaline. Its half maximal effective concentration (EC50) is 0.1 nM. It has a higher in vitro selectivity for β₂-receptors than the related drugs formoterol and salmeterol: 241-fold versus β₁- and 2299-fold versus β₃-receptors.[2] The high β₂/β₁ selectivity may account for the apparent lack of tachycardia in clinical trials, which is mediated by β₁-receptors on the heart.


Once bound to a β₂-receptor, an olodaterol molecule stays there for hours – its dissociation half-life is 17.8 hours –, which allows for once-a-day application of the drug[3] like with indacaterol. Other related compounds generally have a shorter duration of action and have to be applied twice daily (e.g. formoterol, salmeterol). Still others (e. g. salbutamolfenoterol) have to be applied three or four times a day for continuous action, which can also be an advantage for patients who need to apply β₂-agonists only occasionally, for example in an asthma attack.[8]


On 29 January 2013 the U.S. Food and Drug Administration (FDA) Pulmonary-Allergy Drugs Advisory Committee (PADAC) recommended that the clinical data included in the new drug application (NDA) for olodaterol provide substantial evidence of safety and efficacy to support the approval of olodaterol as a once-daily maintenance bronchodilator treatment for airflow obstruction in patients with COPD.[9]
On 18 October 2013 approval of olodaterol in the first three European countries – the United Kingdom, Denmark and Iceland – was announced by the manufacturer.[10]
