What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new inhaler that combines budesonide (a corticosteroid) and formoterol (a long-acting bronchodilator) to evaluate its effectiveness for people whose asthma isn't well-controlled by their current treatment. The goal is to determine the inhaler's effectiveness and safety over 24 weeks. Participants will join different groups to compare this new inhaler with other treatments. Suitable candidates have had asthma for at least six months and find their current inhaler insufficient for symptom control. As a Phase 3 trial, this treatment represents the final step before FDA approval, offering participants a chance to contribute to potentially groundbreaking asthma therapy.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you must be willing to adjust your asthma therapy as required by the study protocol. You should discuss your specific medications with the study team to understand any necessary changes.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that combining budesonide and formoterol is generally safe for people with asthma. Studies have found that this inhaler controls asthma symptoms better than using each medicine alone or a placebo. It also results in fewer asthma flare-ups compared to treatments like fluticasone-salmeterol.

For the budesonide inhaler alone, research suggests it is safe and effective. It improves asthma symptoms both during the day and at night. Users of budesonide have reported fewer emergency room visits and hospital stays.

These inhalers are being tested in the later stages of clinical trials, indicating existing evidence of their safety for humans. However, like any treatment, side effects may occur, so discussing any concerns with a healthcare provider before joining a trial is important. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments for asthma because they offer potential improvements in inhaler therapy. Unlike the standard of care, which often includes separate inhalers for budesonide and formoterol, the Budesonide/Formoterol Fumarate (BFF) inhaler combines both medications into a single metered-dose inhaler, simplifying treatment. This combination inhaler is available in different dosage strengths (160/9.6 μg and 320/9.6 μg), allowing for flexibility based on patient needs. Additionally, the use of a metered-dose inhaler could provide a more precise and consistent delivery of medication compared to some current inhalers, potentially enhancing efficacy and reducing asthma symptoms more effectively.

What evidence suggests that this trial's treatments could be effective for asthma?

Research has shown that using an inhaler with both budesonide and formoterol fumarate greatly improves asthma control compared to using each one alone or a placebo. In this trial, participants may receive the BFF MDI 320/9.6 μg dose, which studies have found particularly effective in controlling asthma symptoms. Another arm of the trial will test Budesonide MDI 320 μg alone, which has also proven to improve symptoms and reduce the need for extra medication. Strong clinical evidence supports both treatments, demonstrating their effectiveness in managing asthma. ^{2 4 5 6 7}

Published Research Related to This Trial

Symbicort, a combination inhaler for asthma and COPD, is more cost-effective than using separate inhalers for its components, budesonide and formoterol, as it leads to lower total treatment costs.

The adjustable dosing strategy of Symbicort not only maintains better asthma control with less medication but also reduces overall treatment costs compared to fixed dosing and other combination therapies.

In a long-term safety trial involving 896 patients with rheumatoid arthritis, tacrolimus at a dose of 3 mg/day was found to be safe and well-tolerated over a median treatment duration of 359 days, with no new adverse events appearing after the first 3 months.

The treatment resulted in significant clinical benefits, with ACR20, ACR50, and ACR70 response rates of 38.4%, 18.6%, and 9.0% respectively, indicating that over 26% of patients experienced at least a 70% improvement in joint symptoms.

In a study of 373 patients with moderate persistent asthma, Symbicort (budesonide/formoterol) significantly improved lung function compared to fluticasone propionate, with greater increases in morning peak expiratory flow (PEF) and fewer asthma exacerbations.

Symbicort also led to better overall asthma control, as indicated by a higher percentage of symptom-free days and reduced reliance on reliever medication, while both treatments were well tolerated.

The fixed combination of budesonide and formoterol fumarate dihydrate is an effective treatment option for asthma in adolescents and adults, providing both maintenance and reliever therapy in a single inhaler, which enhances convenience for patients.

This combination therapy has been shown to reduce the frequency of asthma exacerbations that require oral corticosteroids, although more research is needed to confirm its impact on serious outcomes like hospital admissions and emergency visits.

In a study of 57 elderly patients with rheumatoid arthritis who did not respond adequately to DMARDs, tacrolimus was found to be safe and well-tolerated, with 46.3% experiencing clinical adverse events and 18.5% developing infections.

Tacrolimus treatment resulted in a 50% response rate according to the ACR20 criteria, indicating that half of the patients showed significant improvement in their symptoms over 28 weeks.

In a Phase 3 study involving 279 patients with moderate to severe asthma, fluticasone/formoterol was found to be as effective as budesonide/formoterol in improving lung function, measured by the change in pre-dose FEV₁ over 12 weeks.

Both treatments demonstrated a similar safety profile, indicating that fluticasone/formoterol is a viable alternative to budesonide/formoterol for asthma management.
