Study to Evaluate Efficacy & Safety of Tralokinumab in Subjects With Asthma Inadequately Controlled on Corticosteroids

A Multicentre, Randomized, Double-blind, Parallel Group, Placebo Controlled, 12-Week, Ph 2 Study to Evaluate the Effect of Tralokinumab on Airway Inflammation in Adults With Asthma Inadequately Controlled on Inhaled Corticosteroid (MESOS)

A Multicentre, Randomized, Double-blind, Parallel Group, Placebo Controlled, 12-Week, Phase 2 Study to Evaluate the Effect of Tralokinumab on Airway Inflammation in Adults with Asthma Inadequately Controlled on Inhaled Corticosteroid.

This is a multicentre, randomized, double-blind, parallel group, placebo-controlled, phase 2 study to designed evaluate the effect of a 300 mg dose of tralokinumab administered subcutaneously every 2 weeks on airway inflammation in adults with asthma inadequately controlled on inhaled corticosteroids (ICS) with or without other controllers. Approximately 80 subjects will be randomized. Subjects will receive tralokinumab, or placebo, administered via subcutaneous injection at the study site, over a 12 week treatment period.

Inclusion Criteria:

1. Age 18 to 75 years
2. Documented physician-diagnosed asthma for at least 12 months prior to enrolment (v1)
3. Documented treatment with an asthma controller regimen requiring treatment with ICS (minimum dose of ≥ 250 ug fluticasone propionate via dry powder inhaler equivalents total daily dose) alone or in combination ≥ 6 months and that has been taken at a stable dose for at least 1 month prior to enrolment (v1)
4. Additional maintenance asthma controller medications must be given at a stable dose for at least 1 month prior to v1.
5. At enrolment (v1) the subject must have a predicted normal value (PNV) for the pre-bronchodilator (BD) FEV1>50% and more than 1L.
6. Post-BD reversibility in FEV1 of ≥12% and ≥200 mL at enrolment (v1).

Exclusion Criteria:

1. History of interstitial lung disease, chronic obstructive pulmonary disease (COPD), or other clinically significant lung disease other than asthma.
2. History of anaphylaxis following any biologic therapy.
3. Hepatitis B, C or HIV
4. Pregnant or breastfeeding
5. History of cancer
6. Current tobacco smoking or a history of tobacco smoking for >10 pack-years.
7. Previous receipt of tralokinumab
