About this study

Official title: Proof of Concept Study of Alendronate for Asthma

Beta-2-agonists are effective in reducing airway narrowing in asthma and protecting against stimuli that produce bronchoconstriction. The combination of long-acting beta agonists (LABA) and inhaled corticosteroids (ICS) has become the most commonly used asthma controller medication class in the United States, but unfortunately, even when LABAs are added to ICS and used regularly, 58-81% of patients with asthma fail to achieve total control. Regular use of beta-agonists, both short and long-acting, reduces the ability of these agents to protect against the airway narrowing that occurs in asthma in response to bronchoconstrictor stimuli. We refer to this reduced effect as loss of bronchoprotection. In this proof of concept trial we aim to determine if alendronate, which diminishes beta-2 adrenergic receptor internalization, can reduce the loss of bronchoprotection that occurs with regular use of LABAs, even when used in combination with ICS.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Salmeterol Protected Methacholine Challenge PC20

    Following administration of Salmeterol, the concentration of Methacholine required to produce a 20% drop in FEV1 - measured in mg/ml and reported on log base 2 scale.

    Measured: 8 weeks after randomization

Secondary outcomes (2)
  1. Peripheral Blood Mononuclear Cell ADRB2 Cell Surface Density

    Measured: 8 weeks after randomization

  2. Beta-2 Adrenergic Receptor Agonist-induced cAMP Production

    Peripheral blood mononuclear cells cAMP concentrations measured using isoproterenol (ISO) as a beta-2 adrenergic receptor agonist, and using phosphate buffered saline (PBS) as a positive control. The outcome is expressed as the ratio of cAMP concentration using ISO relative to cAMP concentration using PBS.

    Measured: 8 weeks after randomization

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Alendronate in people with Asthma, run by Milton S. Hershey Medical Center at 10 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Jan 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 14 Dec 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Salmeterol Protected Methacholine Challenge PC20 (time frame: 8 weeks after randomization). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02230332, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Jan 2018; AzTrials last refreshed its copy on 7 Nov 2026.
