About this study

Official title: A Multicenter Randomized Clinical Trial to Study the Effects of Single Doses of MK-8351 on the Early Asthmatic Response to a Lung Allergen Challenge

The primary hypothesis of the study is single doses of MK-8351 will reduce the baseline early asthmatic response (EAR) as assessed by area under the curve from 0-3 hours (AUC0-3hr) of forced expiratory volume (FEV1) when compared to placebo.

Read the detailed description

This is a randomized, placebo-controlled, 4-period study. Eligible patients will undergo a single-blind phase in Period 1, followed by 3 periods during which they will receive low-dose MK-8351, high-dose MK-8351, or matching placebo as a single dose in a random sequence crossover study design.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Low-Dose MK-8351 and High-Dose MK-8351 in people with Asthma, run by Merck Sharp & Dohme LLC.

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 9 inclusion and 18 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The record says: withdrawn, as of the sponsor's last update on 16 Jul 2015. Status can change between updates, so confirm with the study contact before making plans.

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 phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

AUC0-3hr of FEV1 Percent Change From Baseline (time frame: 3 Hours). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 16 Jul 2015.
