What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CVT-301Drug

    Levodopa inhalation powder, will be supplied in capsules containing levodopa (l-dopa), designed to deliver to the lung using the CVT-301 inhaler.

  • CarbidopaDrug

    Also called Lodosyn ®

    Administered orally according to the carbidopa dosing schedule.

Study groups in NCT02633839
Study groupRoleWhat they receive
Adults who smokeExperimentalDay -1, subjects begin pre-treatment of oral dose regimen of carbidopa every 8 hours. Day 1, subjects receive a final dose of carbidopa and 1 hour later, a single dose of CVT-301.
Receives: Drug: CVT-301; Drug: Carbidopa
Adults who don't smokeExperimentalDay -1, subjects begin pre-treatment of oral dose regimen of carbidopa every 8 hours. Day 1, subjects receive a final dose of carbidopa and 1 hour later, a single dose of CVT-301.
Receives: Drug: CVT-301; Drug: Carbidopa

What is being measured

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

  1. Maximum observed plasma drug concentration (Cmax)

    Measured: within 30 min prior to CVT-301 dose administration and specified time points up to 24 hours post-dose

  2. Time to maximum observed plasma drug concentration (tmax)

    Measured: within 30 min prior to CVT-301 dose administration and specified time points up to 24 hours post-dose

  3. Area under the plasma concentration versus time curve (AUC)

    Measured: within 30 min prior to CVT-301 dose administration and specified time points up to 24 hours post-dose

Secondary outcomes (2)
  1. Change in pulmonary function

    Pulmonary function will be measured by spirometry using the guideline specified by the Third National Health and Nutrition Examination Survey (NHANES III)

    Measured: within 90 min prior to CVT-301 dose and at specified time points up to 24 hours post-dose

  2. Number of subjects with Adverse Events (AEs) including Serious AEs

    Measured: up to 3 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CVT-301 and Carbidopa in people with Smoking, run by Acorda Therapeutics at 2 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 5 inclusion and 5 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 14 Jul 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Maximum observed plasma drug concentration (Cmax) (time frame: within 30 min prior to CVT-301 dose administration and specified time points up to 24 hours post-dose). 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 14 Jul 2016.
