Evaluate the safety and tolerability of a single dose of S-1226 (8%) in subjects with mild atopic asthma.

Condition Intervention Phase
Asthma Drug: S1226(8%) Drug: Placebo Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Triple (Participant, Care Provider, Outcomes Assessor)
Primary Purpose: Treatment

Primary Outcome Measures:
  • The number of treatment emergent adverse events (AEs). [ Time Frame: 120 minutes ]

    Subjects will be closely monitored throughout the 2-minute drug and placebo administration periods and for 120 minutes following treatment. Treatment may be stopped at any time at the request of the subject and/or the qualified investigator or delegate.

    Safety and tolerability to S-1226 (8%) will be evaluated through the assessment of adverse events, vital signs, pulse oximetry, biochemistry and hematology testing, urinalysis, 12-lead ECG, physical examination, and pulmonary function (spirometry). These data will be recorded and descriptive statistics and change from baseline for safety parameters will be reported.

Secondary Outcome Measures:
  • Evaluate the efficacy of S-1226 (8%) in comparison to placebo. (evaluated using area under the curve (AUC) of the early asthmatic response (defined as a 20% fall from baseline FEV1 following allergen inhalation) [ Time Frame: 30minutes ]
    Efficacy will be evaluated using area under the curve (AUC) of the early asthmatic response (defined as a 20% fall from baseline FEV1 following allergen inhalation), responder status which is achieving ≥ 25% reversal over placebo of the decrease in FEV1 from allergen challenge within 30 minutes after study treatment, maximum percent reversal of allergen-induced decrease in FEV1 in the first 30 minutes following study treatment administration, and the duration of the ≥ 25% reversal produced by study drug, defined as the interval after S-1226 (8%) administration during which the FEV1 is maintained at ≥ 25% above placebo.

Estimated Enrollment: 16
Study Start Date: January 2015
Estimated Study Completion Date: December 2015
Estimated Primary Completion Date: November 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: S1226 (8%)
The drug S1226(8%), consists of Perflubron and 8% CO2 in a medical gas mixture. The dosage is 3ml delivered as an aerosol/vapour/gas mixture with a Circulaire nebulizer.
Drug: S1226(8%)
The drug S1226(8%), consists of Perflubron (PFOB) and 8% CO2 delivered as an aerosol/vapour/gas mixture with a Circulaire nebulizer. The drug is administered as a single dose during the early phase asthmatic response for 2 minutes.
Other Name: PFOB nebulized with 8% CO2 in medical gas mixture
Placebo Comparator: Placebo
The comparator is normal saline delivered as an aerosol with compressed medical air with a Circulaire nebulizer.
Drug: Placebo
Normal saline nebulized with compressed medical air for 2 minutes during the early phase asthmatic response
Other Name: normal saline nebulized with compressed medical air

  8. Subject has normal laboratory values (normal values as clinically judged by the Investigator) for clinical chemistry, hematology, and urinalysis.
  9. Subject is in general good health based on medical history and clinically acceptable results for the following assessments: physical examination, vital signs, and 12-lead ECG, as assessed by study physicians.
  10. Subject is able to communicate effectively with study personnel and is reliable, willing and cooperative in terms of compliance with protocol.

Exclusion Criteria:

Subjects to whom any of the following applies will be excluded from the study:

  1. Any clinically significant abnormality or abnormal laboratory test results found during medical screening or positive test for hepatitis B, hepatitis C, or HIV found during medical screening.
  2. Subjects who require inhaled β2-agonist medication more frequently than 4 times a week (other than prophylactically prior to exercise) during the 4 week period before screening.

  4. Subjects with frequent emergency room visits for asthma, with prior ICU admission or those with prior intubation.
  5. Presence or history of neurologic, endocrine, hepatic, gastrointestinal or kidney disease or therapy that would jeopardize the subject's well-being by participating in the study.
