Brief Summary:
The purpose of the study is to assess the tolerability and safety of a range of repeated inhaled doses of MDT-637. This includes monitoring effects on pulmonary function and determination of blood levels of MDT-637 following inhalation.

Condition or disease Intervention/treatment Phase
Drug Safety Drug: MDT-637 Phase 1

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 36 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Randomized, Double-blind, Placebo-controlled Study to Assess the Safety, Tolerability and Pharmacokinetics of Inhaled MDT-637 Administered to Healthy Volunteers for 10 Days
Study Start Date : December 2011
Actual Primary Completion Date : February 2012
Actual Study Completion Date : February 2012

Arm Intervention/treatment
Experimental: MDT-637
Active formulation
Drug: MDT-637
Inhaled doses of MDT-637 over a 10 day period
Placebo Comparator: Placebo
Matched Placebo Comparator
Drug: MDT-637
Inhaled doses of MDT-637 over a 10 day period

Primary Outcome Measures :
  1. Safety and Tolerability of 3 escalating doses of MDT-637 dry powder inhalation in healthy volunteers [ Time Frame: Up to 48 days (including up to 28 days of screening period) ]
    Safety measurements include Clinical Laboratory Evaluations, Pulmonary Function Tests (Spirometry), ECG, Vital Signs, Physical Examination and Assessment of Adverse Events.

Secondary Outcome Measures :
  1. Plasma pharmacokinetics for MDT-637 dry powder inhalation [ Time Frame: Multiple plasma samples collected during the dosing period, upto 24 hr post last dose ]
    Plasma Samples will be measured to determine MDT-637 pharmacokinetics
