Assessment of Arformoterol for Chronic Obstructive Pulmonary Disease (COPD) Using Hyperpolarized 3He MRI
October 3, 2012 updated by: Mitchell Albert, University of Massachusetts, Worcester
Assessment of Arformoterol for COPD Using Hyperpolarized 3He MRI
The purpose of this study is to determine efficacy of MR imaging with hyperpolarized helium-3 gas in COPD patients both before and after treatment.

Detailed Description
Hyperpolarized Helium Lung imaging has already been tested and proven to be scientifically possible in patients with a number of pulmonary disorders.
However there is limited data on the sensitivity of this imaging technique, which would be essential for clinical use.
This study is a double blinded study with two cohorts, each cohort being made up of patients with confirmed diagnosis of COPD.
One group will receive a placebo while the other will receive treatment.
A comparison of the data will resume once twenty patients have been consented and completed the study procedures.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Drug Subjects
Patients will be required to breath in individual 1 liter bags of gas while in an MRI to produce lung images.
These bags of gas are each made up of 333mL of Helium-3 gas and 667mL of Nitrogen.
The first three bags will be administered with a break between each of five to ten minutes.
Then the drug aformoterol will be administered and an hour will pass.
BROVANA (arformoterol tartrate) Inhalation Solution is supplied as 2 mL of arformoterol tartrate solution packaged in 2.1 mL unit-dose, low-density polyethylene (LDPE) unit-dose vials.
Each unit-dose vial contains 15 mcg of arformoterol (equivalent to 22 mcg of arformoterol tartrate) in a sterile, isotonic saline solution, pH-adjusted to 5.0 with citric acid and sodium citrate.
After administration of the drug, three additional bags of hyperpolarized helium-3 will be administered, again with five to ten minutes between each bag.

The first three bags will be administered with a break between each of five to ten minutes.
Then the placebo (nebulized saline solution) will be administered (2.1 mL).
After administration of the placebo, three additional bags of hyperpolarized helium-3 will be administered, again with five to ten minutes between each bag.

---|---|---|
Change in Total Ventilation Volume
Time Frame: 2 hours
|
Subjects had hyperpolarized helium-3 MR scans completed before administration of an intervention and 2 hours after administration. These images were compared as described: The change in the total ventilation volume (Litres) measured in the hyperpolarized helium-3 MR image from pre-nebulizer inhalation to post-nebulizer inhalation. |
