Teva filled Biologics License Application for reslizumab

The US Food and Drug Administration (FDA) has accepted for review Teva Pharmaceutical’s Biologics License Application (BLA) for reslizumab, the company’s investigational humanized monoclonal antibody (mAb) which targets interleukin-5 (IL-5), for the treatment of inadequately controlled asthma in adult and adolescent patients with elevated blood eosinophils, despite an inhaled corticosteroid (ICS)-based regimen.

The BLA for reslizumab includes data from Teva’s phase III BREATH clinical trial programme. The programme consisted of four separate placebo-controlled Phase III trials involving more than 1,700 adult and adolescent asthma patients with elevated blood eosinophils, whose symptoms were inadequately controlled with inhaled corticosteroid-based therapies. Results from these studies demonstrated that reslizumab, in comparison to placebo, reduced asthma exacerbation rates by at least half and provided significant improvement in lung function and other secondary measures of asthma control when added to an existing ICS-based therapy. Common adverse events in the reslizumab treatment group were comparable to placebo and included worsening of asthma, nasopharyngitis, upper respiratory infections, sinusitis, influenza and headache. Two anaphylactic reactions were reported and resolved following medical treatment at the study site.

Results from the reslizumab BREATH programme were recently presented at the American Thoracic Society 2015 Annual Meeting and the American Academy of Allergy, Asthma and Immunology 2015 Annual Meeting, in addition to being published in The Lancet Respiratory Medicine. The BLA for reslizumab has been accepted for filing by the FDA for standard review, with FDA Regulatory Action expected in March 2016.

Reslizumab is an investigational humanized monoclonal antibody which targets interleukin-5 (IL-5). IL-5 is a key cytokine involved in the maturation, recruitment, and activation of eosinophils, which are inflammatory white blood cells implicated in a number of diseases, such as asthma. Elevated levels of blood eosinophils are a risk factor for future asthma exacerbations. Reslizumab binds circulating IL-5 thereby preventing IL-5 from binding to its receptor.
