Stallergenes Greer advances its house dust mite allergy pipeline with acceptance of regulatory submission and new market approval

LONDON--(BUSINESS WIRE)-- Regulatory News:

Stallergenes Greer (Paris:STAGR), a biopharmaceutical company specialising in treatments for respiratory allergies, today announced that Health Canada accepted for review the company’s New Drug Submission (NDS) for STG320, an investigational sublingual immunotherapy tablet for the treatment of house dust mite (HDM) induced allergic rhinitis. Once a New Drug Submission is accepted for review it takes usually between nine to twelve months for Health Canada to issue the results of the evaluation.

Stallergenes Greer’s HDM tablet is already available in Japan, Australia and South Korea under the brand name Actair and was approved for commercialization in New Zealand on September 8, 2017.

“We continue to make progress on delivering on our pipeline and expanding our portfolio. We believe STG320 has the potential to be a very important allergy immunotherapy treatment option for patients suffering from allergic rhinitis.”, said Fereydoun Firouz, Chairman and CEO of Stallergenes Greer.

In July 2017, Stallergenes Greer announced the completion of enrollment for the largest Phase III clinical trial to evaluate the safety and efficacy of STG320 in adult and adolescent patients with HDM-induced allergic rhinitis. The study recruited over 1,600 patients from 13 countries. Together with other clinical data, it will form the company’s clinical submission of a Biologics License Application (BLA) in the United States currently planned for 2019, as well as for additional marketing authorizations in European and international markets.
